Oleg Isonen 6d73186a8b fix: Reset Form fields after successful submission (#6583)
After a successful Form submission, a visible Form returns to its
authored field defaults. The newly inserted Form starts blank, so
visitors can send another message without clearing the previous one.

## Checklist
- [x] Call the browser's Form reset after a successful Resource
submission.
- [x] Preserve entered values after failed submissions and keep
Navigation mode behavior unchanged.
- [x] Cover text, selection, and file inputs, including authored
defaults, in focused tests.
- [x] Handle authored fields named `reset` without skipping the reset or
resource refresh.
- [x] Verify Builder Preview and published-site behavior use the same
client path.
- [x] Update the Form guide for the changed behavior.
- [x] Explain the prototype reset call in a short code comment.
- [x] Run focused browser tests, typecheck, formatting, and lint on the
follow-up.
- [x] Verify required CI on the follow-up commit.

The reset test fails when the reset call is removed. The `reset` field
test failed before the review fix. Both pass now.

Oleg Isonen 26ba4728fa docs: Explain Builder feature flags (#6581)
Each Builder feature flag now has a short comment explaining what
enabling it changes.

## Checklist
- [x] Verify latest-head CI.
- [x] Address both flag-description review comments and reply before
resolving their threads.
- [x] Document all five flags next to their declarations.
- [x] Verify the comments against the current flag call sites.
- [x] Review documentation impact: code comments only; no user-facing
docs change.
- [x] Run feature-flags typecheck, formatting, and diff checks.

Follow-up to #6576.

Oleg Isonen dabaeede02 fix: Hide deprecated components in Builder (#6576)
The Components panel now hides deprecated components by default. The
default-off `deprecatedComponents` feature flag shows all nine
registered deprecated components in a separate **Deprecated** section,
including Webhook Form and RemixForm. Webhook Form keeps its saved
component ID, icon, behavior, navigator label, and `w-webhook-form` CSS
class. The command picker continues to hide deprecated components.

## Checklist
- [ ] Document each feature flag beside its declaration using its
current behavior.
- [x] Keep Webhook Form metadata and picker guidance pointing to Form.
- [x] Preserve the generated `w-webhook-form` class without custom
`presetClassName` metadata.
- [x] Hide deprecated components from the Components panel by default;
show all nine eligible components in a dedicated Deprecated section
behind the default-off `deprecatedComponents` flag.
- [x] Keep deprecated components out of the command picker.
- [x] Add focused tests for default and flagged visibility, section
membership, exclusions, and template insertion data.
- [x] Review documentation impact. Existing Webhook Form docs describe
its default unavailability; the flag is for development, so no docs
change is needed.
- [x] Verify focused tests, typechecks, lint, and fixture generation.
The fixture pipeline passed; its unrelated live fixture path drift was
restored.
- [x] Update the Components panel E2E filter assertion for the flagged
deprecated section and verify the rerun.
- [x] Verify required CI on the latest head.

Focused tests: component catalog 16/16, Builder 3/3. Builder,
project-build, and feature-flags typechecks passed. Lint and the full
fixture pipeline passed. The new section tests failed as expected with
section creation temporarily disabled and passed after restoration.
Latest-head CI: Main workflow, Visual regression, Lint PR, and Check
submodules all passed, including all six Builder E2E shards.

Oleg Isonen 534401c66b fix: keep publish progress after closing popover (#6570)
## Summary
- Show the existing validation success toast if validation finishes
after the Publish view closes or switches to Export. Keep it quiet while
the result is visible in Publish.
- Keep publish progress running when the popover closes. Reopening shows
a pending state without restarting the countdown and updates when
publishing finishes.
- Show a completion toast only after the Publish popover closes. Keep
errors and diagnostic findings visible across panel remounts.
- Continue polling a recovered pending build after the popover closes.
Ignore old status responses and superseded manual validation results.
- Keep a manual validation report and its “See issues” button available
after closing and reopening the Publish popover.

## Checklist
- [x] Consolidate publish progress and validation state. The PR's net
non-test change is down from +560 to +457 lines.
- [x] Cover the close/reopen validation result and suppress duplicate
publish-error toasts while Publish is open.
- [x] Run focused tests, Builder typecheck, lint, formatting, and
required CI after the simplification.
- [x] Show the existing validation success toast when validation
finishes outside the Publish view; suppress it while the inline result
is visible.
- [x] Prove the open and closed outcomes with a failing-then-passing
regression test.
- [x] Clear a persisted status error when a successful refresh finds no
build, while preserving request errors.
- [x] Prove the no-build case with a failing-then-passing regression
test and recheck docs, fixtures, and 55 focused tests, typecheck, lint,
formatting, and diff checks.
- [x] Show validation completion when the user switches to Export before
the result arrives, with a failing-then-passing regression test.
- [x] Resolve reviews and pass CI on commit 1b532637a7.
- [x] Cover countdown, completion, errors, remounts, recovery,
navigation, and stale responses with regression tests.
- [x] Keep manual validation findings and the report button visible
after closing and reopening the Publish popover.
- [x] Verify the new regression test fails before the fix and passes
after it.
- [x] Pass 37 targeted tests, Builder typecheck, lint, formatting, and
diff checks.
- [x] Review documentation impact and fixture inputs. The publishing
guide already covers validation reports; no fixture inputs or generated
outputs are affected.
- [x] Resolve all existing review threads.
- [x] Pass all CI workflows on commit 428dee3d35.
- [x] Preserve validated domain selection across popover remounts.
- [x] Ignore delayed diagnostics from superseded publish attempts.
- [x] Guard publish polling across A → B → A navigation.
- [x] Show a recovered failed build after a lost publish response.
- [x] Recheck reviews and CI on commit 51573cd848.
- [x] Suppress publish success toasts whenever the Publish popover is
open, including stale project completions and the Export view.
- [x] Verify both changed regression tests fail before the fix and pass
after it.
- [x] Recheck documentation impact and pass 38 targeted tests, Builder
typecheck, lint, formatting, and diff checks.
- [x] Suppress the validation success toast while the Publish popover
shows its validated state.
- [x] Recheck documentation impact and pass 38 focused tests, typecheck,
lint, formatting, and diff checks.
- [x] Restore validated domain selections through the visible checkbox
state and verify submitted domains match.
- [x] Recheck documentation impact and pass 51 focused tests, Builder
typecheck, lint, formatting, and diff checks.
- [x] Keep the visible checkbox selection in sync when validation
finishes after the popover reopens, without resetting a later user
change.
- [x] Resolve the late-validation review thread and pass CI on commit
3de717d993.

## Verification
- Commit 3d54f6c775 passed all four CI workflows, including all 19
main-workflow jobs and six Builder E2E shards. All review threads are
resolved.
- The close/reopen validation test failed before the fix and passes
after it. The adjusted stale-poll test failed when its ownership guard
was disabled and passed when restored. All 98 Publish feature tests,
Builder typecheck, oxlint, oxfmt, and diff checks pass locally. The
source changes do not affect documentation or fixture inputs.
- Commit 1b532637a7 passed Lint PR, Check submodules, Visual regression,
and Main workflow. All six Builder E2E shards passed. The fixture size
job passed on rerun after its first attempt failed because a React
Router fixture build could not find `build/client/.vite`. All review
threads are resolved.
- The Export regression failed before the fix and passes after it. All
38 focused tests, Builder typecheck, lint, formatting, and diff checks
pass locally. No documentation or fixture inputs are affected.
- The no-build regression test failed before the fix and passes after
it. It verifies that a request error remains visible. All 55 focused
tests and static checks pass locally; no documentation or fixture inputs
are affected.
- The validation toast regression test failed before the fix and passes
after it. All 54 focused tests, Builder typecheck, oxlint, oxfmt, and
diff checks pass locally. No documentation or fixture inputs are
affected.
- Commit 3de717d993 passed Lint PR, Check submodules, Visual regression,
and Main workflow. All six Builder E2E shards passed; shard 3 passed on
rerun after an unrelated Pages drag test failed its first attempt.
Review threads are resolved.
- The late-validation regression test failed before the controlled
checkbox update and passes after it. It checks visible state, submitted
domains, and selection after the report clears. All 51 focused tests,
Builder typecheck, lint, formatting, and diff checks passed.
- The reopened domain checkboxes and submitted form values now match.
The UI regression test failed before the fix and passes after it; it
also checks that toggling a restored checkbox changes the submitted
domains.
- The Validate action already shows “Validated” after success; the
redundant toast is removed. The existing action test covers that state.
- 38 targeted tests passed locally. Builder typecheck, oxlint, oxfmt,
and `git diff --check` passed.
- Commit 428dee3d35 passed all CI workflows, including visual regression
and six Builder end-to-end shards. Latest commit 51573cd848 passed lint,
submodule, visual regression, and the main workflow. All six Builder
end-to-end shards passed; shard 5 passed on rerun after an unrelated
Form feedback test failed, and shard 2 passed on rerun after GitHub
cancelled its first attempt.

Oleg Isonen bc7e58af84 fix: Stabilize Preview and MCP issue reports (#6572)
## Problem

A fresh iterative Preview can lose its rendered content on the first
client navigation with a React `useContext` error. MCP issue reports can
also miss the page or instance ID needed to locate a problem, and
concurrent tool calls can overwrite newer report context with an older
snapshot.

## Fix

- Have Vite scan generated routes before the first navigation. This
applies to the base React Router template and the Netlify and Cloudflare
overlays. It changes local iterative Preview, not saved project data or
production routing.
- Include up to three recent, validated tool targets in MCP issue
reports. A project-relative screenshot path is matched to its page ID;
the CLI does not store the path, full URL, token, or page content. It
cannot read the Builder's current UI selection, but includes an instance
ID when a tool call names one.
- Treat structured MCP error results as failures and serialize
report-state writes within a CLI session, so a concurrent older write
cannot replace a newer result.

The reporting work from #6574 is now included here. #6574 is superseded.

## Verification

- Reproduced #6569 twice with CLI 0.306.0 and a cold optimizer cache.
With the Vite change, a cold `/` → `/blog` navigation and direct article
load rendered without browser errors.
- The config assertion failed without the Vite entry and passed with it.
A proposed optimizer test also passed without the fix, so it was
removed; the real cold-navigation check remains the behavioral evidence.
- The new concurrent-write test passed with serialization and failed
when the queue was temporarily removed. All 106 focused CLI tests, CLI
typecheck, root lint, formatting, and generated API check passed on the
combined branch.
- Earlier checks of the same Preview and reporting code passed: 133
prebuild tests, 144 project-build MCP tests, protocol and Builder
reporting tests, affected typechecks, CLI build, generated docs, and CI
on the separate PRs.
- The fixture build passed without changing tracked files. The full
local fixture pipeline stopped at sync because the development server
returned bundle version `bundle-17o6sch` while this checkout expects
`bundle-1sh9iaz`. The combined commit passed Linux and Windows fixture
checks and all other required CI jobs.
- Full Luna/low agent evaluations were run earlier on the combined
branch: the latest run passed 8 of 9 fixture tasks, while the
managed-form assertion failed on an unrelated task. Saved baselines were
missing or incompatible, so the command failed overall. No baselines
changed. Evaluations were not rerun for this final concurrent-write
change.

## Checklist

- [x] Reproduce and fix the first-navigation Preview failure
- [x] Cover the base, Netlify, and Cloudflare templates and generated
fixtures
- [x] Include safe recent page and instance IDs in MCP issue reports
- [x] Treat structured MCP errors as failures
- [x] Serialize concurrent report-state writes and verify the regression
test fails without the queue
- [x] Review documentation impact: Preview usage and user guidance are
unchanged; no docs change
- [x] Run focused local checks and attempt the fixture pipeline
- [x] Confirm required CI passes on the final combined commit

Oleg Isonen 13eb7527ef fix: route deprecated Webhook Forms through Form backend (#6553)
Deprecated Webhook Forms reuse the existing Form execution pipeline
without teaching the modern backend about WebhookForm.

## User-facing behavior and how to test it
- Existing saved Webhook Forms keep their markup, action settings, and
success/error feedback. Submit a published Webhook Form and check both
outcomes.
- URL and Resource actions preserve configured methods, headers,
dependencies, body overrides, and the last submitted value for repeated
field names. Test a configured action and inspect the received request.
- Default owner notifications use the Email Worker, including submitted
files. Submit a Webhook Form without a custom action and inspect the
owner email and attachment.
- Configured Email actions validate recipients and retain threading
metadata. Test valid recipients and a rejected recipient limit.

## Implementation
- One deprecated Webhook Form adapter calls existing bot validation,
Email preparation, recipient validation, resource loading, and response
handling.
- Both generated route templates call that adapter. Both paths reuse an
internal resource-graph traversal helper; modern submission behavior is
unchanged.
- Root actions use the protected, uncached request override.
Dependencies reuse existing generated Assets and Resource caching
behavior.
- Keep reachable-resource filtering because Email preparation runs
before loading: unrelated Email settings must not break the selected
action.
- Remove dead `getDefaultActionResource` wiring from generated
templates.

## Verification
- Focused SDK tests: 116 passed (11 deprecated Webhook Form adapter and
105 modern submission, Email, and handler tests), including unrelated
resources, missing dependencies, cycles, Email preflight/threading, and
single-attempt Email failures.
- Resource generator tests: 26 passed.
- Full CLI prebuild suite: 139 passed after tracked fixture
regeneration; focused deprecated Webhook Form adapter tests: 9 passed.
- Repository fixture pipeline (`pnpm -r fixtures:build`) passed. All
tracked generated `getDefaultActionResource` references were removed,
and no Builder `N8N_FORM_EMAIL_HOOK` reference remains.
- Final MCP-generated local Preview E2E rerun: 3/3 passed.
- Focused saved Webhook Form custom-action E2E rerun: 2/2 passed (setup
and test), including a single POST through the protected test receiver
after Builder reload.
- SDK, CLI, and Builder typechecks, focused lint and formatting, and
`git diff --check` passed.
- Deprecated component picker regression test passed (2/2); verified it
fails when WebhookForm deprecation is disabled, then passes with
deprecation restored.
- Independent Astra review found no blocker, including the 62 generated
fixture changes. No production deployment or live secret change was
performed.
- Required staging CI checks passed on previous head `15635fc` (Main
workflow, visual regression, submodules, and lint). An unrelated
existing MCP success-redirect E2E assertion failed once in shard 5,
passed in a focused local rerun (2/2 including setup), then shard 5
passed on GitHub rerun without code changes.
- Terminology pass (`4a69ab573`): renamed the dedicated SDK adapter and
migration helper, updated both route templates and generated fixtures,
corrected the active identity migration marker comments, and
synchronized docs and test names. Focused tests passed: SDK 35, CLI
prebuild 12 plus 2 after final title change, MCP 7, migrations 8, React
browser 7, CLI docs 9. Seven affected package typechecks, fixture
builds, formatting, and `git diff --check` passed. That historical head
was superseded; latest-head CI results are recorded below.

- ResourceForm identity migration (`29a21edbb`): focused migration (23),
DB patch (25), project-build DB/session (93), Builder
API/import/auth/patch (60), React SDK (162), runtime/MCP (239), registry
(11), CLI evaluation (90), CLI session/sync (55), and protocol (15)
tests passed; full CLI prebuild (139) passed. Affected typechecks, lint,
formatting, and `git diff --check` passed. Independent Astra review
found no blocker. No deployment was performed.

- Prepublish Webhook Form warning (`25855e8f00`): audit checks every
non-draft published page and links nested/shared instances to the
correct page; modern ResourceForm, native forms, draft-only forms, and
orphans are excluded. Focused audit tests (13), Builder navigation tests
(6), project-build and Builder typechecks, lint, formatting, and `git
diff --check` passed. Independent Astra review found no blocker;
publishing remains nonblocking. No deployment was performed.

- ResourceForm test and CI expectation repair (`e1a527fbcc`): focused
React SDK (24), Builder preview/registry (38), project-build pages (1),
and CLI fixture API (8) tests passed; Remix and React Router targeted
browser suites, affected package typechecks, full formatting (3375
files), lint, and `git diff --check` passed. Astra review found no
blocker. Persisted identity and runtime exports were unchanged.

- Project bundle fixture repair (`70889ef27d`): eight bundles now carry
the current contract version; the two unmarked historical Form instances
in `webstudio-features` normalize to WebhookForm. Protocol fixture tests
(17), protocol typecheck, CLI fixture build, formatting, lint, and diff
check passed. Independent Astra review found no blocker.

- Story/MCP E2E CI repair (`483614e6c5`): SDK CLI story tests (7),
ResourceForm fragment tests (34), and focused local managed-form E2E (4
including setup) passed. SDK CLI and Builder typechecks, lint,
formatting, and diff check passed. Astra review found no blocker. The
initial local Preview build used an ignored stale React Router `lib`
artifact; rebuilding it restored the passing E2E run.
- Latest PR head `483614e6c5`: Main workflow [run
39317777032](https://github.com/webstudio-is/webstudio/actions/runs/39317777032)
passed, including all package matrices and six Builder E2E shards.
Visual regression [run
39317796922](https://github.com/webstudio-is/webstudio/actions/runs/39317796922),
submodules, and PR lint checks passed. The overlapping unapproved visual
run was cancelled by the approved rerun.

- Shared bot-value generator (`ecc4cad1e9`): SDK helper tests (3), React
Router WebhookForm/ResourceForm browser tests (5), SDK/Router/Remix
typechecks and builds, SDK browser-boundary check, formatting, and diff
check passed. Brave bypasses media queries, working media queries
produce a fresh timestamp per submission, and failed queries produce
`jsdom`; each managed/legacy submission has one bot field. Independent
Astra review found no blocker. Latest-head Main workflow [run
39325677117](https://github.com/webstudio-is/webstudio/actions/runs/39325677117)
passed, including all six Builder E2E shards; approved visual regression
[run
39325702835](https://github.com/webstudio-is/webstudio/actions/runs/39325702835),
submodules, and PR lint passed. The superseded visual run was cancelled
by the approved rerun.\n\n- Historical Form clipboard guard
(`e864283d1c`): instance/page transfer parsers reject ambiguous legacy
`Form` before asset import; direct fragment/page/folder mutations
preflight before changes. Canonical ResourceForm, WebhookForm, and
NativeForm remain accepted. Project-build tests (89), Builder paste
browser tests (69), both typechecks, focused lint/formatting, and diff
check passed. Independent Astra review found no blocker. Latest-head
Main workflow [run
39329184890](https://github.com/webstudio-is/webstudio/actions/runs/39329184890)
passed, including all six Builder E2E shards; approved visual regression
[run
39329562692](https://github.com/webstudio-is/webstudio/actions/runs/39329562692),
submodules, and PR lint passed. The earlier unapproved visual run
reported two expected story differences.\n\n## Compatibility notes
- Root HTTP actions reject private and same-origin destinations.
Dependencies retain their existing fetch/cache behavior.
- Routes retain the 25 MiB request limit. Shared execution applies bot
validation, a 10-second Resource timeout, and one retry for eligible
HTTP failures; an ambiguous failure can duplicate an HTTP action. Email
actions are not retried.
- Default email uses the Email Worker's sender, plain text, recipient
limits, and attachment limits instead of the legacy n8n HTML/basic-auth
path.
- Self-hosted sites need normal Email sender configuration. Direct
Builder draft Preview handling is outside this published-route change.
- Coordinate this CLI release with [SaaS PR
#669](https://github.com/webstudio-is/webstudio-saas/pull/669), which
removes the n8n helper and `N8N_FORM_EMAIL_HOOK` from new published-site
builds. Publish with a CLI artifact containing this adapter. Existing
deployed workers retain their bundled code and injected hook until
republished, so keep the actual n8n endpoint available while those sites
remain active.

## Implementation checklist
- [x] Align saved Webhook Form custom-action E2E with the protected
receiver and verify one submission.
- [x] Regenerate tracked published-site fixtures with the updated CLI
and confirm no `getDefaultActionResource` or `N8N_FORM_EMAIL_HOOK`
references remain in Builder source/config/fixtures.
- [x] Review authoritative `docs/` impact of removing the obsolete
Builder hook wiring; related deprecation and integration docs were
updated.
- [x] Route deprecated Webhook Form submissions through the shared
execution pipeline with one adapter.
- [x] Preserve configured actions, dependencies, repeated fields, body
overrides, and saved feedback.
- [x] Prepare and validate Email actions using existing shared logic.
- [x] Remove duplicated orchestration and dead generated context wiring.
- [x] Verify generated routes and MCP-generated Preview submissions.
- [x] Mark the Webhook Form component and its dedicated dependencies
visibly deprecated, while leaving shared Form infrastructure active.
- [x] Group Webhook Form-only SDK code for straightforward removal while
preserving public APIs and generated output.
- [x] Use deprecated terminology consistently for Webhook Form-only PR
code, and clarify the active identity migration marker.
- [x] Confirm required staging CI checks.
- [x] Use ResourceForm as the one active modern component identity
across Builder, SDK, runtime, templates, generated code, and docs.
- [x] Migrate historical Form, NativeForm, ResourceForm, and WebhookForm
identities in one idempotent pass using the historical pages marker.
- [x] Remove the marker from ordinary project and snapshot APIs while
preserving historical input readers.
- [x] Persist pages and instances together when a historical marked
project is saved, including a pages-only edit.
- [x] Verify migration, export/reimport, old CLI and server snapshots,
page-only save, generation, and affected typechecks.
- [x] Complete an independent architecture review before commit or push.

- [x] Warn at prepublish for deprecated Webhook Forms on published
pages, with a link to each affected element.
- [x] Verify modern ResourceForm is excluded and nested/shared Webhook
Forms navigate to the correct page.
- [x] Complete independent review, focused tests, and affected
typechecks before push.

- [x] Remove local `ResourceForm as Form` aliases from React SDK tests
and fixtures; use the canonical component name throughout.
- [x] Fix stale identity expectations found in CI and verify affected
tests/typechecks.
- [x] Complete independent review before push.

- [x] Refresh tracked project bundle fixtures to the current bundle
contract and canonical WebhookForm identity; verify protocol and
affected CLI flows.

- [x] Align SDK CLI story assertions and MCP E2E fragment fixtures with
the persisted ResourceForm component name; rerun affected checks.

- [x] Share one browser bot-value generator across ResourceForm
submission and deprecated Webhook Form wrappers, preserving field
ownership and behavior.
- [x] Verify bot timestamps, Brave/media failure handling, repeated
submissions, affected typechecks, and independent review before push.

- [x] Reject ambiguous historical `Form` clipboard fragments before any
insertion or transfer mutation, with clear recopy guidance; preserve
canonical ResourceForm action remapping.\n- [x] Verify
instance/page/template/folder paste regressions, independent review, and
latest-head CI.\n\n
- [x] Explain Email attachment size limits in the Email action UI and
give a useful error when the aggregate encoded attachments exceed the
local guard.
- [x] Check Preview and published behavior, boundary tests, and
authoritative Form docs; verify the focused change and get independent
review.

Ref #4093
- [x] Preserve safe email codes/messages through MCP, including local
attachment and upload limit errors.
- [x] Correct Form documentation for each enforced limit and verify
Preview/published/MCP paths.
- [x] Verify Builder SDK and MCP focused tests, typechecks, and
independent review before push.

- Email limits and failure copy (`6d215f3ec3`): the shared SDK checks 32
attachments and 7 MiB aggregate Base64 data before dispatch; the 25 MiB
multipart response and Email action guidance use approved copy. Managed
Email error codes pass through Form and MCP results with resource IDs,
while MCP still omits resource bodies. Form docs distinguish the Worker
7 MiB JSON cap from Cloudflare's 5 MiB complete message and
verified-destination exception, and correct the no-retry behavior.
Focused SDK tests 89, Builder API tests 44, UI browser tests 42,
SDK/Builder/CLI/docs typechecks, lint, formatting, and generated MCP
docs check passed. Astra found no blocker. No real email or production
deployment occurred.

- Latest Email limits head `6d215f3ec3`: Main workflow [run
39393037290](https://github.com/webstudio-is/webstudio/actions/runs/39393037290)
passed on rerun, including all six Builder E2E shards; approved visual
regression [run
39393456618](https://github.com/webstudio-is/webstudio/actions/runs/39393456618),
submodules, and PR lint passed. The initial unapproved visual run showed
the same two previously accepted story differences.

- [x] Address review: normalize previous-Builder `Form` instance patches
before persistence, preserve historical WebhookForm identity, and cover
marked/unmarked cases. Documentation impact reviewed: this restores
intended save behavior, so no user guide change is needed.

- Review finding follow-up (`ce05dd733a`): three Form identity patch
regressions passed red/green; full project build-patch tests 28/28,
project typecheck, lint, formatting, and diff check passed. Independent
Astra review found no blocker. Incoming PATCH `Form` is treated as the
immediately previous Builder's modern form alias; already stored
unmarked historical `Form` continues to migrate to WebhookForm. The old
patch protocol has no client-release identifier, so pre-October-14 live
clients adding new ambiguous IDs cannot be identified separately.

- Latest review-fix head `ce05dd733a`: Main workflow [run
39397337356](https://github.com/webstudio-is/webstudio/actions/runs/39397337356)
passed, including six E2E shards after a targeted shard-4 rerun for an
unrelated MDX slash-menu timeout. Approved visual regression [run
39397395206](https://github.com/webstudio-is/webstudio/actions/runs/39397395206),
submodules, and PR lint passed. The unapproved synchronize visual run
was cancelled by the approved rerun.

Oleg Isonen cdfef44a6a fix: Resolve recent content and CSS issues (#6567)
Closes #6554
Closes #6555
Closes #6557
Closes #6559
Closes #6560
Closes #6563
Ref #6558
Ref #6564

## Change
- Preserve `color-mix(... var(...))` in border shorthands, including
when width or style is omitted.
- Keep bound JSON-LD objects intact, generate valid conditional Content
Block JSX, accept truly empty content queries, and reject missing source
fields.
- Let custom Open Graph values replace defaults and avoid evaluating a
Content Block source in the server loader when it has no Resource
dependencies.
- Add bounded error type and request ID diagnostics to automatic MCP
reports. This helps investigate future #6558/#6564 occurrences; it does
not claim to fix those unreproduced write failures. The generated API
contract is updated.
- No persisted-data migration or new user-facing format is needed.

## Verification
- New border and missing-source regressions failed before their fixes
and pass afterward. Focused package tests, all eight affected package
typechecks, lint, generated-API and package-boundary checks pass on the
combined branch.
- `pnpm fixtures` completed. Its only differences were unrelated remote
fixture content (`/acme-test` → `/olegs-test`), excluded from this PR.
- Full local Luna/low agent evaluations: 8/9 fixtures passed.
`managed-form-runtime-v1` missed its action check, also seen on earlier
separate runs. Comparison baselines are incompatible or absent; none
were updated.
- Required CI is green after the simplification: main workflow
(including all Builder E2E shards), visual regression, submodules, and
PR lint.

## Checklist
- [x] Reproduce the six fixable reports and cover them with regressions.
- [x] Investigate #6558/#6564 and add safe diagnostics for future
reports.
- [x] Address and resolve all review comments on the three original PRs.
- [x] Review documentation impact: existing product docs describe the
intended behavior; report diagnostics are internal, so no docs update is
needed.
- [x] Critically review and simplify the combined diff; verify focused
tests and package checks.
- [x] Simplify recursive content-query evaluation state and verify its
regressions.
- [x] Required PR CI passes after the simplification.

Oleg Isonen fc38f71ba2 docs: Document self-hosted email tRPC interface (#6542)
Document the email service interface used by the Builder's server-side
tRPC call.

- Specify `POST /trpc/email.send`, bearer authorization, project-ID
metadata, direct JSON input, attachment encoding, and the tRPC
delivery-result envelope.
- Document `TRPC_SERVER_API_TOKEN` and `EMAIL_SERVICE_URL`, including
the current restriction to approved Webstudio Worker origins. The docs
do not claim that an arbitrary self-hosted origin can be configured
today.
- Keep the endpoint contract focused on its external HTTP interface.

Validation:
- A clean-room implementation from the original REST wording returned
404 for the Builder's `/trpc/email.send` request.
- I discarded it, revised the docs, then tested from scratch using the
actual Builder `createCloudflareManagedFormEmailSenderWithUrl` helper
from this PR head against a local fake tRPC endpoint. Success and
delivery-failure responses passed; the emitted URL, method, headers, and
direct JSON payload matched the contract.
- Confirmed the actual Builder helper rejects an arbitrary self-hosted
URL. The endpoint used a fake provider; no email was sent.
- The focused SDK managed-form email suite passes: 57 tests.
Documentation only; no deployment.

Oleg Isonen 2c20db0d01 fix: Parse font shorthand with variable families (#6551)
## Summary

- Parse `font-size / line-height` structurally so a custom-property font
family does not swallow the line-height.
- Add parser, shorthand-expansion, and fragment-insertion regression
coverage.
- Document the semantic conversion sequence for composite media,
preserving wrappers while deleting obsolete provider parts.

Closes #6547
Closes #6544

## Verification

- `pnpm --filter @webstudio-is/css-data test -- src/shorthands.test.ts
src/parse-css.test.ts` — 4,326 passed, 1 skipped
- `pnpm --filter @webstudio-is/project-build test --
src/runtime/components.test.ts src/runtime/instances.test.ts` — 181
passed
- CSS data, project-build, and CLI typechecks
- CLI docs generation
- GitHub Actions: all workflows passed (including all six Builder E2E
shards)

## Checklist

- [x] Regression tests added for the reported behavior.
- [x] Docs impact reviewed; MCP manuals and generated docs updated.
- [x] Diff and generated documentation verified.

Oleg Isonen 37429b2aad docs: Refresh Variables section and dialog guide (#6543)
## Change
- Match documentation navigation and links to the Builder **Variables**
section label, including the Flotiq setup path.
- Refresh the Variables guide against the current new variable dialog:
available types, name validation and shadowing, resource editors,
previews, and actions.
- Preserve “data variables” where it names the data concept and keep
existing Resource and GraphQL link anchors.

## Verify
- `pnpm check:generated-docs` passed.
- `git diff --check` passed.
- Reviewed the docs-only diff against the dialog editors and current
labels.

Oleg Isonen fad586889a feat: Paste copied variables with keyboard (#6549)
## Summary

- Recognize copied variable payloads in the design mode keyboard paste
pipeline.
- Keep variable clipboard utilities in the shared copy/paste folder so
both the settings-panel feature and shared paste handling import from
shared code.

## Verification

- Oxfmt and Oxlint passed for the changed Builder files.
- All CI checks passed on the latest commit, including typecheck, tests,
E2E, and visual regression.
- Local Vitest and typecheck could not start because this checkout is
missing existing dependencies (`email-addresses`, `ipaddr.js`, `undici`,
and `tldts`).

Oleg Isonen cb0cc5c125 fix: load inspected external resources in Builder (#6548)
## Summary
- Keep inspected Resource loads on the same URL + RequestInit fetch path
as ordinary loads. The Request object is retained only for exchange
inspection.
- Fix the Resource editor Refresh action for external APIs without
changing Builder's existing public-IP guarded Node transport.
- Add a refresh-button test, a deterministic inspected POST test, and
opt-in live GET checks for the Holy Redeemer API.

## Tests
- `pnpm --filter @webstudio-is/sdk exec vitest run
src/resource-loader.test.ts --reporter=dot` (60 passed)
- `pnpm --filter @webstudio-is/builder exec vitest run
app/builder/features/settings-panel/variable-editors/http-resource-refresh.test.tsx
--project core-browser-builder-settings --reporter=verbose` (1 passed)
- `WEBSTUDIO_LIVE_RESOURCE_GET=1 pnpm --filter @webstudio-is/builder
exec vitest run app/services/safe-resource-fetch.live.server.test.ts
--project core-server --reporter=verbose --silent=false` (3 passed;
normal and inspected GET returned 200)
- SDK and Builder typechecks; `oxlint` and `oxfmt --check` on changed
files

## Runtime note
The current Vercel Builder still uses its Node public-IP guarded
transport. A future Cloudflare Worker transport requires a separate
migration with `global_fetch_strictly_public` enabled; this PR does not
switch to unrestricted fetch.

Oleg Isonen 8439a1a644 fix: Report runtime errors from MCP screenshots (#6545)
A screenshot could return success when a generated page rendered a React
error boundary. The HTTP response and Webstudio root marker were valid,
so the error was easy to miss.

The capture now records browser JavaScript exceptions and error-level
console events. MCP path screenshots of generated projects return
`SCREENSHOT_JAVASCRIPT_ERROR` instead of success when either is
detected. Other URL-based captures keep their existing behavior.

Closes #6538

### Checklist

- [x] Capture JavaScript exceptions and error-level console events from
the browser.
- [x] Reject generated-project screenshots with a structured error code.
- [x] Add regression coverage and verify the tests fail before the fix.
- [x] Review authoritative documentation; no documentation change is
needed for this error-reporting correction.
- [x] Run vision and CLI tests, typechecks, lint, and a local Chrome
React error-boundary capture.

### Verification

- `pnpm --filter @webstudio-is/vision test` — 103 passed.
- `pnpm --filter webstudio test` — 1,278 passed.
- `pnpm --filter @webstudio-is/vision typecheck` — passed.
- `pnpm --filter webstudio typecheck` — passed.
- Oxlint and `git diff --check` — passed.
- Local Chrome end-to-end: an HTTP 200 page rendered a React error
boundary and was identified as a JavaScript error.

Local agent evaluations were not run; they require explicit approval.

Oleg Isonen 3f18f44456 fix: Align Form Action add button with panel headers (#6541)
## Change

Settings collapsibles now use `fullWidth` so right-side Builder Style
and Settings panel content owns its inline padding. Existing visual
insets are preserved, and Action explicitly owns its zero inset so its
header and action rows can span the section width.

- Forward `fullWidth` through `CollapsibleSectionWithAddButton`.
- Remove the `fullWidth` prop and padding wrapper from `StyleSection`;
all ten StyleSection callers own their content insets locally, including
Size's zero inset and full-width separator.
- Move Properties & attributes, diagnostics, individual Style panel
section insets into their own content.
- Keep normal property controls inset and let Action control its own
header, rows, error, and redirect spacing.
- Retain the earlier Form Action add-trigger and resource-row changes.
Action content starts below its full section header with a small gap.

## Implementation

- [x] Prevent overlap between the Action section header and its items:
start content below the full header with the existing 2px gap,
preserving row size and inset.

- [x] Review padding-only wrappers from the right-side Settings and
Style panel refactors. Apply padding directly to an existing Flex
container where possible and remove redundant Box wrappers.

- [x] Replace the Action dropdown hardcoded 180px minimum width with the
closest existing spacing token, `theme.spacing[26]` (176px; 4px
narrower).
- [x] Review documentation impact for the dropdown token change:
reviewed the Form action documentation; no update required.

- [x] Remove the `fullWidth` prop from `StyleSection`. Each individual
Style panel section content container explicitly owns its inline
padding: ordinary sections retain 12px and Size retains zero inset, with
existing gaps preserved.

- [x] Give CollapsibleSection content zero inline padding using the
existing `fullWidth` API for right-side Builder Style and Settings panel
sections. Each section explicitly owns its inline padding, preserving
current visual insets and allowing sections such as Action to control
alignment.

## Verification

- Action spacing: 13 focused Chromium browser tests, focused oxlint,
formatting, and `git diff --check` passed. Geometry asserts a 36px
header, 2px gap before the first item, button clearance, and unchanged
24px row height.

- Restored Page Settings to its original padding ownership; all 7
focused Page Settings Chromium tests, focused oxlint, and `git diff
--check` passed.

- Padding-wrapper follow-up: removed redundant Box wrappers around the
Navigation mode Flex and baseline Action header fixture; audited
right-side Settings and Style panel padding owners. 10 focused Action
Chromium tests, focused oxlint, and `git diff --check` passed.

- Dropdown token follow-up: 13 focused Action Chromium tests, focused
oxlint, and `git diff --check` passed. The browser assertion verifies
the 176px computed minimum width.

- 428 Style panel Chromium browser tests passed after moving padding
into individual sections.
- 43 focused Chromium browser tests passed: Action, PropsSection, page
settings, search, diagnostics, and request inspector.
- Builder TypeScript check, focused oxlint, and `git diff --check`
passed.
- Assert the Properties collapsible has zero inline padding while its
child owns its 12px inset; existing Action geometry checks pass.

Oleg Isonen c389cd3bb2 fix: classify errors with structured codes and types (#6539)
Invalid or revoked share links now return an actionable 401 response
instead of an unexpected server error. Missing project and workspace
records receive distinct responses at their lookup sites. Token,
project, and workspace lookups use `.maybeSingle()` and rely on database
uniqueness. Missing projects have an explicit `ProjectNotFoundError`;
the loader no longer interprets `PGRST116`.

The API preserves `UNAUTHORIZED` and `INVALID_AUTH_TOKEN` when
authorization fails during context creation, so CLI and MCP clients can
offer relinking guidance without inspecting error text. Tokens without
API access carry `API_ACCESS_DISABLED`.

A repository audit replaces error-message matching with typed errors,
stable codes, or structured diagnostics in CLI argument/configuration
handling, session conflicts, preview cleanup, import retries, domain
unpublishing, asset validation, JSX/expression diagnostics, CSS
validation, and publish diagnostics. `AGENTS.md` now explicitly
prohibits message-based error classification and recovery.

The existing build-permission preflight now advertises structured
import-error support. Clients upload assets before importing into older
servers that do not advertise it; newer servers keep selective retries
using structured missing-file details. The internal template-validation
error class remains outside public JSX bindings and input descriptions.

Shared Builder `parseError` normalizes tRPC and local validation errors,
so UI components only add display context instead of decoding transport
payloads.

Simplification removes three redundant error classes, catch-and-ignore
handlers, an unused formatter, and nested loader error handling.
Unpublishing an already unpublished domain succeeds after authorization.
CLI configuration failures use the existing shared error handling, and
plan parsing catches only JSON parsing failures.

Validation: affected suites passed (271 tests across 8 suites in the
latest simplification checks), affected package typechecks passed, and
lint, package-boundary checks, and `git diff --check` passed. The audit
replaced synthetic parser branches and private-method assertions with
actual tRPC round trips, PostgREST responses, and public VM behavior.
Controlled regressions confirmed that removing serialized validation
details and exposing the internal JSX error class both fail the revised
tests. Astra reviewed the production changes at medium effort; its
compatibility finding and the GitHub JSX-binding comment are fixed, and
follow-up review found no remaining substantive issues.

Oleg Isonen 33f7b350bc fix: Improve Form setup and email settings guidance (#6536)
## User-facing features and how to test them

- Project Settings → Emails → Reply to has an info tooltip explaining
how its display name is used in visitor confirmation subjects and
messages, and when “Site Owner” is shown. Test it by hovering or
focusing the info icon.
- When a Form has no resources available for its Action, clicking the
Action + button explains that a resource must first be created in
Variables. Test it with a Form that has no action-capable resources,
then create a resource and verify it can be added to the Action.
- Success redirect is shown inside the Action control only when Resource
actions are connected. Test by switching between navigation mode and a
Form with a Resource action; the redirect field should appear only for
Resource actions, and its saved value should return when a Resource
action is added again.
- The Action control no longer offers Disable/Enable. Connected Resource
actions run in their configured order. The Form Action model has no
`enabled` field; older saved JSON with that extra key is read as an
ordinary connected action.

## Verification

- Focused UI test for the Reply to tooltip.
- Focused UI test for the empty Action resource tooltip.
- Manually verify Success redirect visibility and value retention while
switching modes.
- Manually verify all connected Actions execute in order, including
older saved Actions carrying an ignored `enabled` key.


## Review follow-up

- Address all current open code review comments on this PR, verify the
fixes, and reply to each addressed thread before resolving it.

## CI repair follow-up

- Inspect the latest failing checks on this PR, fix the causes on the
existing branch, and verify the affected checks locally and in CI.

## Follow-up audit (2026-10-14)

- Audited head `8fb0b44`, all inline review threads and the PR
conversation. The earlier Reply to tooltip comment was answered and
resolved. Two P1 comments remained: required boolean `enabled`
validation in CLI evaluations, and execution of saved disabled actions.
- `builder-e2e (shard-6)` failed because Preview returned `Disabled`
between `First` and `Last` in the configured failure results test. The
failure matches the security review finding. `builder-e2e (shard-2)` was
still in progress at audit start; the staging deployment workflow was
cancelled.
- The follow-up filters saved disabled actions from execution and
restores boolean `enabled` validation in both CLI evaluations. Builder
labels saved disabled actions. Focused SDK (55), CLI (222), and Builder
(45) tests, plus all three affected package typechecks, passed locally.
- Pushed `7c2b90e082`; replied to both P1 review threads, then resolved
them. Its main CI run passed all 25 test/check jobs, including all six
Builder E2E shards and the previously failing shard 6.
- A later P2 review identified stale CLI/MCP guidance. Commit
`160a9d1707` corrects the source and generated docs; focused docs tests
(12) and CLI typecheck pass locally. Replied to and resolved that
thread. On this latest head, the main CI run completed successfully: 27
check jobs passed, including all six Builder E2E shards; one
visual-regression job was skipped. All three required checks passed. The
automatically triggered staging deployment workflow was cancelled under
the no-deployment instruction.


## Input type default follow-up

- Show `text` as selected in the Props panel for both the HTML `input`
element and the Input component when their `type` prop is unset,
matching their rendered default. Verify both variants in the Builder and
retain explicit type choices.


## Current review-thread follow-up (2026-10-14)

- Recheck every unresolved review thread against the current PR head,
make and validate any required fixes, and reply with the resolution
before closing each thread. Keep this work on the existing PR branch; do
not deploy.


## Input type metadata follow-up (2026-10-14)

- Move the unset input `type` display default into component/element
property metadata for both the Input component and native HTML `input`
element. Remove the Props-panel special case, keep the implicit default
out of saved props, and cover both variants with regression tests.
- Run focused checks, push the fix to this PR, and cancel any
automatically triggered staging deployment workflow. Do not deploy
manually.


## Props metadata selector simplification follow-up (2026-10-15)

- Refactor `$selectedInstancePropsMetas` after the input default
metadata change. Preserve the current metadata, ordering, and attribute
override behavior while simplifying the selector's structure and
abstraction boundaries.
- Run focused checks, commit and push to this PR branch. Cancel any
automatically triggered staging deployment; do not deploy manually.

## Latest review follow-up (2026-10-15)

- Audit the latest PR head, all unresolved inline review threads, and
general PR comments. Address actionable feedback on this branch, run
focused validation, then reply and resolve each addressed thread. Cancel
any automatically triggered staging deployment; do not deploy manually.


## Form Action model decision (2026-10-15)

- Remove the Form Action `enabled` field completely from the type,
serialization, validation, execution, fixtures, and current docs. Accept
older saved JSON containing that extra key by ignoring it, including
`enabled: false`; action presence and valid IDs determine execution.
- Update the CLI evaluation to assert intended action IDs and order
without using `enabled`. Address the latest P2 review finding against
this model. Run focused checks, push on this PR branch, and cancel any
automatic staging deployment. No manual deployment.


## Action control visual follow-up (2026-10-15)

- Match the Form Action plus button to the established Variables section
plus button style and implementation where appropriate. Keep the
existing icon.
- Give the Action resource dropdown a stable width comparable to the
Variables resource dropdown, including when available resource names are
short.
- Add focused UI coverage, validate locally, commit and push to this PR
branch, and cancel any automatic staging deployment. Do not deploy
manually.


## Action plus hover follow-up (2026-10-15)

- Match the Action `+` button's hover and focus styling exactly to the
plus buttons in panels such as Variables. Compare their actual
implementations, preserve the existing icon, and add focused UI coverage
where appropriate.
- Run focused checks, commit and push to this PR branch. Cancel and
confirm any automatically triggered staging workflow; do not deploy
manually.


## Current CI fix (2026-10-15)

- Inspect the latest check rollup and failing job logs on the current PR
head. Fix all current failures on this branch, run focused local
validation, push the changes, and monitor the new head until checks
complete.
- Cancel and confirm any automatically triggered staging deployment. Do
not deploy manually.

Oleg Isonen 59d4f00ce7 feat: new Form component, all features and improvements you dreamed of (#6485)
## User-facing features and how to test them

In Components → Forms, insert **Form (Beta)**. The existing Webhook Form
remains a separate component.

- **Insert a ready-to-use contact Form.** In Components → Forms, insert
**Form (Beta)**. It starts with accessible Name, Email, Subject,
Message, and optional Attachment fields; sends submitted field values
and uploaded files to the account holder; sends a customizable
confirmation to the visitor without attaching the submitted file; and
includes success and error feedback. The two Actions are named **Email
to owner** and **Email to visitor**. *(#3023, #5499)*
- **Use the contact Subject in both email subjects.** Owner and visitor
subjects bind the submitted Subject input; the visitor subject also
identifies the sender. Template and SDK tests pass.
- **Format submitted Form data readably in Email bindings.**
`formData.toString()` now renders labeled lines, nested values, and
uploaded filenames in any Email Resource expression, while excluding
passwords and internal Form fields. SDK and independent-bundle tests
pass. Published staging delivery is verified in Batch 7.
- **Choose Form actions.** Select the Form and open Properties &
Attributes → Action. Add up to ten visible HTTP, GraphQL, or Email
Resources; reorder, disable, or remove them. Submit and confirm enabled
actions run together. *(#5499)*
- **Send submitted fields and files.** Submit repeated fields and a file
input to an HTTP Resource. Check the received multipart fields, order,
filename, type, and bytes. Email Resources attach submitted files by
default; turn off **Attach submitted files** to omit them. *(#3023,
#5432)*
- **Make the visitor confirmation friendly and signed.** Inherited
content gets the approved friendly message and resolved sender name;
custom text remains intact. Email Request preview and delivery use the
same resolver. SDK and Builder preview tests cover defaults, custom
overrides, blank content, sender identity, and preview parity. Suggested
body:

  > Thank you for your message.
  >
  > We received it and will respond as soon as possible.
  >
  > Webstudio Team
- **Identify the sender in the visitor confirmation.** The resolved
sender name appears in the visitor subject and body. Focused tests pass.
- **Include source page context in the owner email.**
`browserInfo.pageUrl` is included in the owner message and the Email
Request preview. Focused SDK and Builder tests pass.
- **Use Form and visitor data.** In a Resource defined on the Form, bind
`formData` and `browserInfo` in its URL, headers, or body. Local MCP
Preview tests verify submitted fields, browser, and language. *(#5428)*
- **Use page and query values.** On a dynamic page with query
parameters, bind `system.params` and `system.search` in a Form Resource,
then navigate and submit. A query key with one value is a string;
repeated values are an ordered array. Confirm the current route values
are available after navigation. Text bindings render repeated values as
comma-joined strings. *(#5512, #3891)*
- **Use Navigation mode for search and filters.** Remove every Resource
from the new Form’s Action list. Its action becomes
`?__webstudio__=navigate`, and submitting named fields updates the URL
query and page Resources without a full page reload. Reconnect a
Resource to return to Resource submission mode
(`?__webstudio__=resources`). A plain Element with tag `form` keeps
native browser behavior.
- **Customize notification email.** In Project Settings → Emails, set
recipients, sender, and Reply to. In each Email Resource, choose project
recipients, custom addresses, or a visitor email input, and configure
its Reply to, subject, body, and attachment setting. Verify a
per-Resource override does not change another Form’s settings. *(#4414,
#4385, #5658)*
- **Choose Resource types from one ordered list.** In Variables → Type,
find REST resource, GraphQL resource, Assets resource, Email resource,
Sitemap resource, and Current date resource in that order. Confirm the
labels and order in the Type dropdown.
- **Inspect Resource requests and responses.** Open Variables → a
Resource → Edit variable. Use **Load data** on Request when no request
is shown; inspect HTTP request, response, and diagnostics. For Email,
load the request preview and confirm it does not send an email. After
submission, inspect saved HTTP and GraphQL exchanges without triggering
another request. *(#4093 related; new Form Resource inspector)*
- **Explain the Email Response before a submission.** Refresh builds the
local request preview without sending an email; the Response tab tells
users to submit the Form in Preview to see the Email Service response.
Focused inspector test passes.
- **Use action results in the Form.** Bind `formState`, `results`, and
`errors` in the success and error content. Submit successful and failing
actions and verify each result or error includes its action’s response
details in configured order. *(#5499)*
- **See submission feedback.** Submit a Form whose success or error
message is outside the viewport and confirm that message scrolls into
view. Repeat with feedback already visible, reduced motion, partial
failure, and a configured success redirect; visible feedback should not
move, and redirect should happen without scrolling first. *(#6487)*
- **Redirect after success.** Set Success redirect and submit both
successful and failing Forms. Only success follows the redirect.
*(#3530)*
- **Keep separate email threads.** Retries preserve a submission
reference, while separate submissions appear in separate Gmail
conversations; Batch 7 verifies both. *(#5018)*
- **Keep existing Webhook Forms.** Insert the existing Webhook Form and
verify its configured behavior remains intact. For its documented
query-binding fixes, verify route params and repeated search values
after navigation. *(#5512, #3891; #4093 and #5432 remain related legacy
issues)*

- **Keep native Form props out of the new Form editor:** The new Form
metadata hides generated rendered-tag HTML props such as `method`,
`encType`, `target`, and ARIA attributes, while its own Action, Success
redirect, and visibility controls remain. The legacy Webhook Form
behavior is unchanged. A Builder property-selector regression test
verifies this.

- **Allow up to 10 Form Actions:** The shared validator and Action
picker now allow up to 10 Resource actions, and the Form control
description reflects the limit. SDK tests accept 10 and reject 11; the
generated CLI prebuild rejection coverage passes (130 tests). SDK and
SDK Components typechecks, formatting, and diff checks pass.

- **Make the default Form ready to use without edits:** The inserted
contact Form has required Name, Email, Subject, and Message fields; its
project Email Action resolves the current project contact address or
account holder dynamically, with no personal data in the template; its
visitor Email Action has a confirmation subject and message; success and
error states give actionable feedback. `core-templates.test.tsx`
verifies fields, routing, and copy; focused registry tests and typecheck
pass.

- **Make the default Form usable as a contact form:** Its Email Actions
are named “Email to owner” and “Email to visitor.” The owner body binds
the complete submitted `formData` object rather than manually listing
fields, and an optional Attachment input sends its file only to the
owner. Email Resource expressions render `formData.toString()` as
readable labeled lines. The visitor receives a confirmation without
submitted files. Registry/template tests and MCP E2E verify the inserted
Form, owner message and attachment, visitor message, and Request
preview.

- **Format Form action errors clearly:** The default Form shows each
action error as a spaced bullet inside a red-tinted alert panel.
Registry template tests verify the alert and list structure; 8 template
tests pass.
- **Deprecate the existing Webhook Form before its next-PR removal:**
The component metadata and compatibility exports in the React, React
Router, and Remix packages are marked deprecated, and the guide says
removal is planned. Keep form submission helpers still used by
NativeForm active; remove legacy-only wrappers and template in the
follow-up PR.

## MCP feature parity test plan

Run these cases through Webstudio MCP on a disposable project. Create
and configure the Form with MCP, save and read back the configuration,
then test its generated Preview. Use only a controlled test mailbox for
real email delivery. This plan mirrors the user-facing UI cases above.

- Discover **Form (Beta)**, inspect its schema, insert the default
contact Form, and read back its fields, Actions, success/error content,
and absence of personal data.
- Change the submitted Subject and Name. Verify owner and visitor
subjects, visitor sender identity, friendly confirmation text, and the
owner page URL.
- Bind the complete `formData` object. Verify readable lines, nested
values, filenames, and exclusion of password/internal fields.
- Add HTTP, GraphQL, and Email Actions; reorder, disable, and remove
them. Verify concurrent dispatch, result order, partial failure, and the
10/11 Action limit.
- Submit repeated fields and one or multiple files to HTTP. Verify
multipart order, filename, MIME type, and exact bytes. Verify Email
attachments default on, then turn them off for the visitor Action and
confirm the visitor receives no file.
- Configure project email settings and Resource overrides. Save/reload
each recipient mode, Sender, Reply to, subject, body, and attachment
setting; verify overrides do not leak between Forms.
- Bind `formData` and `browserInfo` from a Form-scoped Resource. Verify
page URL, browser, language, and hosting-provided IP/referrer where the
test environment supplies them.
- Test dynamic route params and single/repeated query values before and
after navigation. Verify Navigation mode updates the URL and bound page
Resources without a full reload; reconnect an Action and verify Resource
mode. Check native `form` Element behavior separately.
- Verify Resource discovery order and method labels, then exercise
HTTP/GraphQL Request, Response, Diagnostics, load/refresh, and saved
exchange inspection. For Email, verify request preview sends nothing and
the Response appears after actual submission.
- Bind `formState`, `results`, and `errors`. Submit success, validation
failure, partial Action failure, and full failure. Verify feedback
content, visible/off-screen scrolling, reduced motion, and success-only
redirect behavior.
- Submit twice and verify separate email threads and stable retry
identity, with no duplicate delivery after an ambiguous send.
- Verify the existing Webhook Form remains editable and its route/query
behavior remains intact, while new Form discovery/creation and native
Form prop exposure match the documented component contract.

### Execution status and MCP limitation

The `mcp-*` suite authors through a current-source MCP server and
submits generated Preview Forms through `preview.submit-form`.
Playwright covers Builder UI, navigation/rendering, and viewport
assertions. The separate `forms.simulate-submission` operation submits
synthetic values from the saved canvas Form directly to the shared SDK
server Form engine, without starting Preview or a browser. Both paths
use the same saved-draft preparation and SDK submission handler. Most
automated email tests use a loopback receiver. The controlled
branch-source MCP test below separately verifies delivery to a real test
mailbox; it does not test the user’s connected MCP release.

On 2026-10-14, the branch-source MCP was tested against a running local
Builder and a copied disposable project. No npm package publish or
connected-MCP release was needed for this local verification.

- [x] Add a bounded `preview.submit-form` MCP operation for
session-owned generated Preview Forms. It uses native form controls and
validation, supports repeated values and bounded file uploads, returns
state/results/errors/exchanges, and never replays an ambiguous send. The
MCP-client E2E verifies one owner Email delivery and one HTTP delivery
with ordered results against local receivers. Focused Vision, Project
Build, CLI, and Builder E2E tests pass.
- [x] Migrate browser Preview Form runtime cases to
`preview.submit-form`; retain Playwright for Builder UI,
navigation/rendering, and viewport assertions. The 52 MCP-named Builder
E2E cases passed across the full 2-worker run (50/52) and a focused
rerun of its two timed-out Email cases (2/2), including MCP submission
and local receiver assertions.
- [x] Add `forms.simulate-submission` to the current-source CLI MCP
session. It reads the saved canvas Form, calls the Builder server route,
and reuses the Preview Form engine and SDK submission handler. The older
local CLI adapter rejected Email; the current server route supports it.
Static Checkbox and multiple Select array names come from saved
controls; dynamic array names may be supplied explicitly. Focused tests
and independent Astra Medium review pass.
- [x] Run the Luna Low `managed-form-runtime-v1` scenario against
`forms.simulate-submission` through a real MCP client on the current
source. `gpt-5.6-luna` at low reasoning passed 10/10 checks in 55
seconds. Three simulation calls produced success, an explicit 503
failure, and recovery against the controlled local HTTP receiver in the
expected sequence. The agent used no Preview/browser submission or Email
action. One `templates.get` MCP error was recovered before submission.
- [x] Verify `forms.simulate-submission` from branch-source MCP against
the local Builder server and a disposable saved Form. The supported
local database was started, and `EMAIL_SERVICE_URL` plus
`TRPC_SERVER_API_TOKEN` were supplied from the staging Infisical
environment without printing values. Luna Low used MCP discovery,
Form/resource inspection, `update-resource`, and simulation. Both Email
Resources resolved only to `testing@webstudio.is`; simulation returned
success, HTTP 200, two Email results with status 200, and no errors.
Gmail independently confirmed both owner and visitor messages delivered
to that controlled inbox at 15:46:51 UTC on 2026-10-14. The shared
server route and CLI transport received independent Astra Medium review;
focused CLI (164) and HTTP-client (45) tests, package typechecks,
formatting, and diff checks pass. No npm release or production
deployment was involved.

- [x] Rename the new Form component label to **Form (Beta)** in the
component picker and MCP discovery. Component IDs stay unchanged;
focused registry, Builder, MCP, and CLI tests pass; Astra Medium
reviewed the change. Pushed `592589ccfe`.

## MCP end-to-end verification

### Verified against this branch

These checks use the current-source MCP session server to author
disposable local Builder projects and `preview.submit-form` to submit
generated-site Forms to local test receivers. Playwright verifies
Builder UI, navigation/rendering, and viewport behavior. They verify
this branch's code, not the connected MCP release, staging services, or
real mailbox delivery.

Current branch rechecks (2026-10-14): Project Build MCP tests 142/142,
CLI MCP/evaluation harness tests 60/60, Vision CDP/Form tests 48/48, and
the React Router Navigation browser test 4/4 pass. Builder, CLI, Project
Build, Vision, and both React Router fixture typechecks pass; scoped
lint, formatting, and diff checks pass. The earlier head passed PR CI;
checks on commit `7438692ef5` are running. The separate full CLI
prebuild suite now passes 131/131 after adding the required `statusText`
to its private Email binding fixture. The main-merge CI failures in
Project Build expression expectations, CLI Preview config import,
formatting, and the SSG fixture size cap were fixed in `0272768260`;
checks on that commit are pending.

- [x] Verify all 52 MCP-named Builder E2E cases on the current head. The
complete 2-worker run passed 50/52; two complex Email cases exceeded
Playwright's 120-second per-test limit under concurrency, then both
passed in a focused one-worker rerun (44.4s and 31.0s; 2/2). A serial
full rerun reached 43/52 without assertion failures before the wrapper's
900-second command limit. An earlier full run passed 52/52 before the
final Preview readiness fix. Coverage includes contact Forms, Email
delivery and partial updates, attachments, readable `formData`, HTTP and
GraphQL Actions, navigation and repeated query values, legacy Form
editing, Resource inspectors, Form properties and type choices,
feedback, and redirects. Full-run command:
`E2E_TEST_COMMAND_TIMEOUT_SECONDS=1800 E2E_SKIP_BUILDER_BUILD=true
E2E_INSTALL_PLAYWRIGHT=false pnpm --filter @webstudio-is/builder e2e --
'mcp-' --project=chromium --workers=2`.
- [x] Run the Builder Preview Form E2E suite serially: 5/5 passed,
including authenticated Builder Preview submission, error rendering,
redirects, submitted browser `FormData`, off-screen feedback scrolling,
and Navigation mode without a Resource POST or canvas reload.
- [x] Verify the local Email inspector server path. The route
integration suite calls the real local `/rest/preview-form` handler and
passes a controlled Email Service binding response through it; 28/28
tests pass. The Email Service boundary is stubbed, so this does not
claim a staging Worker run.
- [x] Verify the Form Action picker browser tests: 2/2 pass for add,
disable, reorder, remove, the ten-Action limit, and rejection of an
eleventh Action. The MCP runtime E2E separately verified ten deliveries
and ordered results.
- [x] Verify local Preview request context across two pages: scoped
`formData`, `browserInfo.pageUrl`, trusted IP, user-agent, and language
all remain associated with the correct Form Resource.
- [x] Verify partial Email body updates through MCP. Custom and
explicitly blank bodies preserve the other recipient, sender, and
attachment settings; local Preview uses the requested body. Focused E2E
passes 2/2.
- [x] Verify the default Form template has no hardcoded email address,
sender, or recipient, and the error Collection renders each message as a
separated bullet in a red-tinted alert. Registry tests pass 11/11.
- [x] Verify the Action picker UI adds, disables, reorders, and removes
HTTP, GraphQL, and Email Resources; accepts 10 and blocks 11. Component
browser tests pass 2/2. Runtime MCP E2Es separately verify Action order
and concurrent dispatch; the picker test does not claim ten live
deliveries.
- [x] Verify the Luna Low managed-Form authoring evaluation: 20/20
checks pass. Validator tests pass 83/83.
- [x] Verify the legacy Webhook Form is excluded from new MCP
creation/copy paths while saved instances remain editable. Source tests
and the existing 139 MCP checks pass; this does not mean the published
MCP catalog has been refreshed.
- [x] Formatting, `git diff --check`, and Builder, CLI, and SDK
Components Registry typechecks pass.

## Runtime correctness

- [x] Prevent automatic retry of an Email Action when the Email Service
send may already have succeeded; report an ambiguous response without
sending the same email again, and verify one Form submission cannot
produce duplicate delivery. Pushed `07627e44fa`: Email Actions never
automatically replay; HTTP retries remain. RPC and Preview accept legacy
`{id}` and canonical replies, including successful canonical replies
with an empty provider ID. Regression tests cover one dispatch after
failures, timeouts, and malformed replies, response compatibility, and
HTTP retry. All 143 focused SDK tests, SDK typecheck, scoped lint, diff
checks, and independent Astra review pass.

- [x] Keep ambiguous Email Action outcomes non-retriable in Builder so a
possibly successful send is never replayed; preserve compatibility with
both deployed legacy `{id}` and canonical `{ok, status, statusText,
data}` Worker replies. Pushed `578a1a99`: canonical delivery IDs must be
nonblank, while legacy replies remain supported. SDK regressions cover
one dispatch after ambiguous RPC/Preview failures, timeouts, malformed
replies, and empty IDs.

## New Form navigation mode and MCP E2E (2026-10-11)

- [x] Give the new Form two submission modes using its valid action URL:
`?__webstudio__=resources` when one or more Resources are connected and
`?__webstudio__=navigate` when none are connected. Removing the last
Resource switches to Navigation mode. Keep a plain `form` Element native
and leave the legacy Webhook Form available but marked deprecated until
the next release. Runtime tests cover both action markers; the
MCP-authored browser E2E verifies navigation query updates and Resource
revalidation. Legacy Webhook Form metadata, compatibility exports,
component code, and docs now state its deprecation and support window.
- [x] In the new Form’s Action control, when no Resources are connected,
show centered “Navigation mode” with an info tooltip: “Submits the form
fields as URL query parameters and navigates without a full page reload.
Use this for search and filters that update page Resources from the
URL.”
- [x] Add MCP-authored end-to-end coverage for both modes and their
distinctions. Luna/low authored Resource and Navigation Forms plus a
native `form` Element through MCP, with separate registry searches for
Form (Beta), Webhook Form, and Element; the final project passes the
corrected structured evaluator. The MCP-authored Playwright E2E removes
all Form Actions and verifies repeated and single query values update
the URL and page Resource without a document reload or Resource POST.
Existing local MCP Preview coverage verifies Resource submission, native
GET behavior, legacy Webhook Form compatibility, and component
discovery.

## Ports from the earlier implementation

- [x] Resource selection and scoped `formData`/`browserInfo` access,
parallel dispatch, protected egress, server destination limits, and
bot-field validation are already in the new Form.
- [x] Resource editor URL autofocus and known header/value suggestions
are already reused.
- [x] Centralize the `formData` and `browserInfo` parameter names for
Builder, generator, and runtime checks.
- [x] Default HTTP body forwarding and automatic multipart for uploads
are now ported to the new Resource graph.
- [x] Success/error state slots and success redirect are now ported into
the new Form and Router/Remix adapters.
- [x] Add response `results`/`errors` bindings and one retry per failed
or timed-out destination.
- [x] Port feedback scrolling to the new Form in Router and Remix
adapters, with browser regression coverage.
- [x] Adapt the existing bot-field protection for the new Form; saved
Webhook Forms keep their prior bot-field behavior. The narrowly scoped
route/query fixes for #5512 and #3891 are tracked separately below.
- [x] Local new-Form bot checks: one fresh hidden value per submission,
five-minute expiration, malformed/missing rejection before dispatch,
Brave handling, and stripping internal form ID/bot fields before
Resource delivery. Evidence:
`packages/sdk/src/managed-form-submission.ts`,
`managed-form-submission.test.ts`,
`packages/sdk-components-react/src/form-submission.browser.test.ts`, and
managed generated-route cases in `packages/cli/src/prebuild.test.ts`.

## Batch 1 — New Form foundation

- [x] Make the existing Forms-section **Form** tile insert the new Form
component while retaining the existing Webhook Form tile and behavior.
- [x] Make the new Form a managed Resource submission component. With no
destination, it shows a configuration error and cannot dispatch or
navigate. Use Element with `tag=form` for ordinary browser form
behavior.
- [x] Exclude unrelated legacy-only runtime work from this feature.
Existing component metadata is deprecated; the new Form has no legacy
compatibility or migration contract. The targeted #5512/#3891
route/query fixes are tracked separately in Batch 2a.
- [x] Verify the Resource-only component with focused render tests,
package typecheck, and component story generation.
- [x] Verify the Batch 1 new Form acceptance criteria in the Builder and
browser.

### Acceptance criteria

- Inserting the new Form creates the default contact Form with named
inputs, a submit button, and two selected Email Resource Actions: one
for project recipients and one for the visitor email field. If all
destinations are removed, it shows a configuration error and cannot
dispatch or navigate until a destination is configured.
- Element with `tag=form` retains browser validation, method, encoding,
action, and navigation.
- Acceptance covers the new Form only. Apart from the explicitly tracked
#5512/#3891 route/query binding fixes in Batch 2a, legacy compatibility,
old native-mode settings, and old-component migration are outside the
feature contract.

**Verification:** Builder catalog and insertion tests; Chromium
empty-Resource blocking test; generated Element `tag=form` Playwright
test with a local receiver
(`packages/sdk-components-react/src/element-form.test.tsx`,
`40c6f972c8`, focused 1/1) proves invalid input sends nothing and valid
native multipart POST navigates using the configured action, method, and
encoding; generated published output for the new Form; relevant
typechecks and lint.

The user confirmed the test inbox received the test email attachment.
Staging Builder Preview verified Email and Webhook delivery. The user
confirmed the published staging route is live; the route returns HTTP
200 and includes a file input. Published delivery to both Webhooks and
final Form-state behavior are verified in Batch 7 below. Live Production
Form submissions are outside this PR’s verification scope.

## Batch 2 — Resource-only submission, scoped data, and Resource
selection

- [x] Give the new Form one submission path with one to ten selected
Resource destinations. Keep Actions and Success redirect as its Form
controls; plain HTML forms use Element with `tag=form`. An empty
selection reports an error without dispatch or navigation; tests cover
this path.
- [x] Expose one submission-only `formData` object, keyed by HTML name.
Repeated names are ordered lists; a known unchecked checkbox group is an
empty list. Preserve files and hidden inputs.
- [x] Expose safe `browserInfo`: trusted IP, user agent, language, and
referrer. Never expose raw request headers, cookies, or authorization.
- [x] Make explicit Resource expression bindings to a Form's `formData`
and `browserInfo` available only to Resources defined within that Form;
a selected HTTP Action with an unset or empty body implicitly receives
submitted Form data regardless of Resource scope.
- [x] Resource variables are created in **Variables** at their normal
scope. The Actions selector lists only action-capable Resource variables
visible in the Form's variable scope: defined on the Form or one of its
ancestors. Exclude sibling, descendant, and unrelated scopes. Resources
defined on the Form can bind its `formData` and `browserInfo`; ancestor
Resources cannot bind values from a descendant Form. Carry forward URL
autofocus and known header/value autocomplete. Enforce up to ten Actions
per Form in the Builder and server.
- [x] Keep **Actions** as a control inside **Properties & Attributes**,
with a plus menu and selected Resource rows. The plus menu offers only
existing action-capable HTTP, Email, and GraphQL Resource variables
visible in the Form's current variable scope (defined on the Form or an
ancestor); exclude System data variables and resources from sibling,
descendant, or unrelated scopes. Resource variables are created in
**Variables** at their normal scope; Actions only selects existing
variables. Disable already-selected Resources in the menu. Selected rows
expose enable, disable, and remove controls. A simple click on the
Action name opens the existing Resource editor through selection/open
state, leaves its Variables row visibly selected, and scrolls it into
view, while preserving page and canvas selection; drag, enable/disable,
and remove controls must not open it. The eye toggles enabled state; the
minus removes the Action from this Form only. Preserve explicit
selection, ordering, and the ten-Action limit. Published-site submission
checks are recorded in Batch 7.
- [x] Cover scope, expressions, repeated names, renames, files, copying,
deletion, save/reload, and unavailable bindings with focused tests.
- [x] Ensure `mapResourceExpressionsMutable` remaps Email
`senderExpression` and `recipientsExpression` data-source IDs;
`fragment.test.tsx` verifies copy/paste/fragment rebinding (focused
regression 1/1, full file 34/34). Project-build typecheck and `git diff
--check` pass.
- [x] Add focused fragment coverage for Email `senderExpression` and
`recipientsExpression` bound to variables inside a copied Form,
asserting references remap to the cloned variable IDs (not only
restoration of external parent bindings by name). `fragment.test.tsx`
passes 34/34 and combined project-build data+fragment tests pass
165/165; assertions verify both expressions remap to cloned variable IDs
distinct from the source IDs.
- [x] Implement and locally test Batch 2a current-page parameters and
repeated query values in managed and legacy Form Resource bindings
(#5512, #3891).
- [x] Add generated published-route loader integration coverage for a
native GET Form with repeated query keys; repeated `system.search`
values reach an expression-bound Resource in both `defaults` and
`react-router` templates. Focused prebuild tests pass 2/2.
- **Issue scope:** #5512 is fixed for legacy generated HTML Form actions
and the new Form path; generated-route tests cover both route templates.
#3891 exposes repeated values as ordered arrays through `system.search`
while preserving strings for single values; SDK, Builder Preview,
generated action, and generated native-GET loader regressions cover the
behavior.
- [x] Local #5512/#3891 implementation and regression: the new Form's
generated action uses current `system.params` and `system.search`, where
repeated values are ordered arrays; SDK search tests and the Builder
native GET preview test preserve repeated values
(`packages/cli/src/prebuild.test.ts`,
`packages/sdk/src/system-search.test.ts`,
`apps/builder/app/canvas/interceptor.test.ts`).
- [x] Locally verify #5428: bind trusted `browserInfo` values into
`X-Forwarded-For`, `User-Agent`, and `Accept-Language` Resource headers,
inspect the generated action’s outbound request, and document the setup
and trusted client-IP source for each hosting adapter without forwarding
cookies or authorization.
- [x] Local generated-route verification (`e9d5209882`): Remix and React
Router send the three configured headers to a test destination;
Cloudflare context uses `CF-Connecting-IP`, Node omits unavailable IP,
and arbitrary forwarding, cookie, and authorization headers are not
forwarded. Setup and hosting sources are documented.

### Form property inventory

- [x] Expose only the Actions control and **Success redirect** as Form
controls. The generic HTML attribute picker and native `id`, `class`,
`action`, `method`, `target`, and `encType` controls are unavailable for
this component.
- [x] Rename the Form control label from **Actions** to singular
**Action**.

Staging verification for the Form property panel is recorded in Batch 7.

### Acceptance criteria

- Action and Success redirect are the only Form controls. The component
label `Form` is system metadata and is not editable as an HTML
attribute; the Form has no `id`, `class`, `action`, `method`, `target`,
or `encType` controls.

- **Action** is a control inside **Properties & Attributes**. Its plus
menu offers only existing action-capable HTTP, Email, and GraphQL
Resource variables visible in the Form's current variable scope (defined
on the Form or one of its ancestors). It excludes System data variables
and Resources in sibling, descendant, or unrelated scopes. Resource
variables are created in **Variables** at their normal scope; Actions
only selects existing variables. Already-selected Resources are disabled
in the menu. Selected Resources appear as rows with enable, disable, and
remove controls, and can be reordered. Clicking an Action name opens the
corresponding Resource’s existing Edit variable dialog and highlights
its Variables row by setting the existing selection/open state directly,
without synthetic clicks; preserve the current page and canvas
selection. Drag, enable/disable, and remove controls do not open the
editor. The ten-Action limit is enforced. Resources defined on the Form
can bind that Form's `formData` and `browserInfo`; ancestor Resources
are visible but cannot bind values from the descendant Form. An empty
selection shows no canvas warning before submit; attempting to submit
shows the configuration error, dispatches nothing, and does not
navigate. The Form has no native or direct-URL submission mode.
- The new Form supports Resource Actions only; do not add a
legacy/native-mode compatibility path or migration requirement.
- A Resource defined on the Form can bind that Form's `formData` and
safe `browserInfo`; a visible ancestor Resource cannot access values
from its descendant Form. Resource variables are created in Variables at
their normal scope. The plus menu lists only existing action-capable
Resources from the Form and ancestor scopes, excluding sibling,
descendant, unrelated scopes, and System variables. Forms explicitly
select each action; none are auto-added. Already-selected Resources are
disabled in the menu. Bindings survive editing and save/reload.
- On a `/products/:slug` page visited as
`/products/chair?source=newsletter`, a submitted Resource can use
`system.params.slug` as `chair` and `system.search.source` as
`newsletter` in its URL, headers, or body. Values come from the current
submission's page, including after navigation; missing parameters remain
absent.
- Repeated names retain form order, unchecked checkbox groups resolve to
empty lists, and files stay file values. The Resource editor focuses URL
and suggests known header names and values.

## Batch 2a — Keep page parameters and every selected query value
(#5512, #3891)

New Form Resource bindings must receive the current page's parameters,
and a multiple-select GET form must not lose selections when a binding
reads the URL.

- [x] Extend #5512 route/query propagation to legacy native Form
actions: generated routes pass route params and ordered query values
while preserving the managed Form path. The regenerated runtime contract
and 26 fixture routes are pushed in `8c4bda7791`; `check:generated-api`,
fixture builds, and generated-route regressions pass.
- [x] Implement route/query propagation in both managed and legacy Form
Actions: populate `system.params` from the current route, preserve
single-value `system.search` strings and expose repeated query values as
ordered arrays through the same binding. Generated action and loader
regressions cover both templates; the consolidated CLI prebuild suite
and focused native-GET loader tests pass.

- [x] Verify #5512 with the new Form's Resource bindings using
`system.params` and `system.search`. Cover URL, header, and body
bindings, dynamic pages, missing values, and submission after navigation
in React Router and Remix.
- [x] Reproduce #3891 with a native GET form and a multiple-select
input. Keep the browser's standard repeated query keys; do not join
values with commas or rewrite the submitted URL.
- [x] Use `URLSearchParams` to preserve every value in order, including
empty values, repeated identical values, and values containing commas or
encoded characters. Keep an object-based binding interface so property
autocomplete still works.
- [x] Inspect existing `system.search` consumers and record the
compatibility choice here. Keep existing single-value bindings working,
expose all repeated values to bindings, and make any changed behavior
for existing repeated-key bindings explicit. Do not silently discard
values or break existing expressions.
- [x] Apply the agreed representation consistently in the Builder,
published page data, client navigation, and new Form action path. Update
affected types, binding suggestions, generated code, and fixtures.
- [x] Add passing SDK, Builder, and generated-route regressions for
current page parameters and repeated query values in new Form bindings;
document single-value and ordered multi-value query bindings with
working examples.
- [x] Local new-Form generated-route regressions cover current page
parameters and repeated query values in URL, headers, and body after
navigation. A red-before/green-after test proves configured body
bindings survive alongside submitted fields; CLI binding examples
document single and repeated query values.
- [x] Record regression coverage for #5512/#3891 on new Form bindings:
generated-route and Builder tests cover current-page parameters and
ordered repeated, empty, comma, and encoded query values, with SDK
coverage for scalar compatibility.

**Compatibility choice:** `system.search[name]` is a string when the
query key occurs once and an ordered string array when it occurs more
than once. Existing single-value expressions are unchanged; text
bindings stringify arrays as comma-separated values. The relevant
consumers in Builder system/preview and generated page/action templates
were reviewed. Focused SDK, Builder, and generated-route tests cover the
behavior.

### Acceptance criteria

- On a `/products/chair?source=newsletter` page, a new Form Resource can
bind `system.params.slug` as `chair` and `system.search.source` as
`newsletter` after navigation. Existing Webhook Form behavior is
unchanged except for the explicitly tracked #5512/#3891 route/query
binding fixes in Batch 2a.
- Selecting two options in a native GET form leaves both values in the
URL and makes both available to bindings in their original order.
Single-value access still works, and property autocomplete remains
available.
- Empty values, identical repeated values, commas, encoded characters,
reloads, and client navigation do not drop or corrupt query values.
- Verify current-page and repeated-query bindings for the new Form and
ordinary Element `tag=form` browser behavior. Legacy Webhook Form
changes are limited to the explicitly tracked #5512/#3891 route/query
fixes in Batch 2a; other legacy compatibility is not a closure
condition.

## Batch 3 — HTTP Resource submission

- [x] POST to each selected HTTP Resource. A selected Action whose
Resource body is unset or empty implicitly receives all submitted fields
regardless of Resource scope; an edited body can omit, rename, add, or
compute fields. Explicit `formData` expression bindings remain limited
to Resources defined within that Form.
- [x] Use JSON for text-only data and switch to multipart when the
resolved body contains a file. Set JSON content type unless configured
otherwise; preserve repeated fields and file bytes, and remove stale
`Content-Type` so fetch writes the multipart boundary.
- [x] Add an explicit `auto`/JSON/multipart choice. Reject an
incompatible body before that destination's fetch; dependency-free
requests are preflighted before any destination dispatch.
- [x] Resolve bindings and validate final outbound URLs and redirects
before sending. Block internal and private destinations; keep
credentials and sensitive request configuration off the public page.
- [x] Add generated-site and server tests for JSON, multipart, mapping,
files, repeated fields, invalid configuration, and destination safety.
- [x] New Form route proof: compiled Remix and React Router managed
actions forward repeated same-name text values and uploaded files as
separate multipart entries, preserving order, duplicate values,
filenames, MIME types, and bytes (`3c5b72a`; focused CLI tests passed
2/2). Existing Webhook Form behavior remains at its pre-PR baseline;
migration is out of scope.
- [x] Make file inputs easy to configure in the Builder: choose the file
input type and set its field name, required state, accepted file types
(`accept`), and multiple-file selection (`multiple`). Keep these
settings after saving, reopening, and publishing. Verified on
`d7f67307f9` with Builder insert/save/reopen, generated page, Chromium
required/optional/multiple upload, SDK template, typecheck, lint, and
format checks.

### Acceptance criteria

- Every selected HTTP destination receives POST. A Resource with an
unset or empty body receives all Form data implicitly, regardless of
where the Resource is defined. Explicit `formData` expression bindings
remain limited to Resources defined within that Form. Text-only bodies
arrive as JSON; bodies with uploads arrive as multipart with field
names, filenames, MIME types, file bytes, and repeated values.
- A site creator can add and configure a file input using the Builder
without custom code. Published forms support one or multiple selected
files, block submission when a required upload is empty, and submit
normally when an optional upload is empty. The `accept` setting guides
the file picker; it is not server-side file validation.
- An edited body can rename, omit, add, or compute fields. A Resource
outside the Form sends only its own configured data.
- An incompatible explicit body format fails before its destination
fetch. Dependency-free requests are validated before any dispatch; a
body that depends on another Resource is validated once that dependency
resolves, before its own destination fetch. Resolved destinations and
each redirect reject private or internal addresses, and secrets stay off
the public page.

## Batch 4 — Project Emails settings and Resource editor

- [x] Add Project Settings → **Emails**. Move the current Contact email
list without changing its stored value.
- [x] Configure site-wide defaults for Sender (name and email, or email
alone), recipients, owner subject, and plain-text owner body. Published
sites receive project default changes after republishing.
- [x] Add the Email Resource as a normal Resource, creatable inside or
outside a Form. It can inherit, override, and reset project defaults.
Only a Form-scoped Email Resource can bind that Form's data. Surface an
unavailable Form-only binding clearly; never send incomplete template
text silently.
- [x] Resolve team recipients from the project list or owner fallback,
support a custom comma-separated override, and default Sender to the
owner with a per-Resource override. Form data cannot choose team
recipients.
- [x] Configure the subject, plain-text owner body, and whether
submitted files should be attached. With no project body or Resource
body, any selected non-Visitor Email Resource uses readable submitted
fields and optional `browserInfo` interpolation, regardless of Resource
scope. Automatic owner-email text includes hidden fields while excluding
passwords and internal bot fields.
- [x] Test project settings storage, inheritance/override/reset,
recipient fallback, Form scope, expression validation, and preservation
of the existing Contact email setting. A complete project owner body
containing `${...}`, backslashes, or backticks renders as literal text;
an empty project body retains the automatic `formData` and `browserInfo`
interpolations.

### Acceptance criteria

- Existing Contact recipients appear in Project Settings → Emails
without data loss. Existing legacy forms retain their pre-PR behavior
except for the explicitly tracked #5512/#3891 current-page route and
repeated-query bindings.
- New Email Resources inherit published project defaults until
overridden; reset restores inheritance, and settings edits affect live
sites only after republishing.
- Team recipients use the project list or fall back to the owner. A
custom comma-separated recipient list and Sender override work;
submitted values cannot choose recipients or From.
- With no project owner body or Resource body, a selected non-Visitor
Email Resource uses readable submitted-field and `browserInfo` content
regardless of whether it is defined on the Form, an ancestor, or
globally. Explicit expressions can bind Form-only values only from
Resources defined within that Form. A nonempty project body is the
complete literal owner message, inherited until a Resource body
expression overrides it; reset restores inheritance. Automatic text
includes hidden form fields but excludes passwords and internal bot
fields.

## Batch 4a — Sender and recipient email format (#4414, #5658)

Use one **Sender** field that accepts either `Acme Support
<support@example.com>` or `support@example.com`, using the same address
format as recipients. The optional name becomes the displayed sender
name, and the entered email receives replies. Webstudio's authenticated
From address stays fixed.

- [x] Add the Sender field in Project Settings → Emails, with
inheritance, override, and reset in each Email Resource. Default it to
the project owner's email. This single field supplies the display name
and Reply-To; do not add separate sender-name and Reply-To inputs.
- [x] Parse Sender as exactly one mailbox and retain its optional name
and reply address; a plain email has no custom display name.
- [x] Use the site owner profile username as the default visible From
name when Sender has no explicit name; explicit Sender names take
precedence, and missing usernames fall back to “Site Owner”. Keep the
authenticated From address fixed.
- [x] Accept plain and named mailboxes in the Contact email list,
project recipients, and Email Resource recipient overrides.
- [x] Verify existing project address-count limits remain enforced
through both Builder and server updates; the separate five-team-delivery
runtime cap is tracked in Batch 5.
- [x] Use `Acme Support <support@example.com>` as the Sender placeholder
and `Acme Support <support@example.com>, team@example.com` in email-list
inputs.
- [x] Use an established email-address parser in Builder and server
validation. Handle quoted names containing commas, such as `"Example,
Alexs" <support@example.com>`, reject malformed addresses and
header-injection input, and count parsed recipient mailboxes including
duplicates for the runtime delivery cap.
- [x] Preserve parsed display names in generated Email Resource requests
and keep existing plain-address settings readable.
- [x] Test both Sender formats, mixed recipient parsing,
inheritance/reset, generated request values, and the five-team-delivery
runtime cap.
- [x] Local Builder E2E verifies Project Emails Sender and named
recipients save to persisted project settings and remain after reopening
(`b9ebf21fee`;
`apps/builder/e2e/tests/project-settings-runtime.[shard-2].[shard-5].[shard-6].e2e.ts`;
focused run 2/2).
- [x] Document the Sender/recipient input format, reply behavior,
inheritance, republishing, visitor Email Resource delivery, and the
current Cloud-unavailable delivery status without claiming that saving
settings sends email.
- [x] Local generated-graph verification (`1730840feb`): a translated
project body is the entire literal request body, a Resource body
expression overrides it, reset restores inheritance, and an empty
project body retains automatic `formData`/`browserInfo` text. Project
Emails help and docs explain plain-text behavior.

### Acceptance criteria

- Entering `Acme Support <support@example.com>` in Sender displays “Acme
Support” as the sender and directs replies to `support@example.com`,
while From uses Webstudio's sending address.
- Entering only `support@example.com` works without a separate name
field and directs replies to that address.
- With a plain Sender address, the visible From name uses the site owner
profile username, or “Site Owner” if unavailable; a named Sender
overrides it. The From address remains Webstudio’s fixed sending
address.
- Plain and named recipients can be mixed in a list; a quoted comma
inside a name does not create another recipient.
- Names and addresses survive saving, publishing, and delivery, and
existing plain-address settings continue working.
- The project owner confirmed that the email customization already
planned in Batches 4 and 4a is sufficient to close #4414 and #5658.
Sender supplies the display name and reply address; Webstudio remains
the authenticated sender. Do not add custom From addresses,
sending-domain verification, or a separate follow-up requirement to
close these issues. Do not describe Reply-To as a custom From address.
- Site creators can edit the notification subject, plain-text template,
content, and language, with project defaults and per-Resource overrides.
Together with Batch 4, this covers the email customization requested in
#4414.

## Batch 5 — Email delivery and visitor confirmation

- [x] Implement the Cloud-only `EMAIL_SERVICE` adapter for new Email
Resources. Attach every submitted file by default; preflight the 5 MiB
encoded-message and 32-attachment limits and return explicit service
errors. Staging published-Form Email delivery is verified in Batch 7.
- [x] Implement visitor confirmation as an ordinary Email Resource
selected in Actions, addressed through a submitted visitor email field
and dispatched alongside other Actions. Its optional body starts empty
and uses the existing Resource editor and expression bindings. Email
Service prepends a mandatory confirmation preamble with the site URL.
Remove the Form-level confirmation toggle and email-field selector; SDK
and generated-route tests cover delivery.
- [x] A failed visitor-addressed Email Resource appears in `errors` and
does not change aggregate Form success; SDK tests cover this.
- [x] Before any destination runs, count team-recipient deliveries
across all reachable Email Resources, counting duplicates and shared
dependencies once. Reject the whole submission above five at runtime;
permit at most one visitor-addressed receipt separately. No
cross-Resource Builder or publish-time cap substitutes for this
preflight.
- [x] Local subject validation (`1fa8e66d9d`): resolved Email Resource
subjects must be strings without CR/LF. Validate after expressions are
evaluated and before any selected destination dispatch. SDK tests cover
CR/LF from direct `formData` and `browserInfo` subject bindings and zero
provider or selected fetches
(`managed-form-resources-generator.test.ts`,
`managed-form-submission.test.ts`, `resource-loader.test.ts`; focused
tests 88/88 passed). Dependency-bound Email is rejected after any
required lookup and before selected destination dispatch.
- [x] Verify resolved owner and visitor-confirmation subjects in the
generated server path with provider fakes. Owner subject preflight
covers CR/LF from visitor-derived bindings before any selected
destination or provider send; confirmation subject preflight likewise
sends no HTTP or email request. Published staging delivery is verified
in Batch 7.
- [x] Test the local private-service envelope and response path with a
provider fake: recipients, Reply-To, optional Sender display name, plain
text, attachments, recipient and size/count preflight, privacy,
confirmation ordering, partial failure, quota error, and zero sends on
failed preflight. Compiled Remix and React Router action tests cover
confirmation with an HTTP sibling and Node's explicit unsupported
response.

### Cloudflare Email Sending integration plan

Companion SaaS PR:
[webstudio-is/webstudio-saas#666](https://github.com/webstudio-is/webstudio-saas/pull/666).
The Email Service contract uses the canonical Worker
`webstudio-email-service`, Cloudflare's native per-location Rate
Limiting binding, and the private `EMAIL_SERVICE` service binding for
published-site sends to `https://email-service.internal/v1/send`.
Builder Preview uses the authenticated shared Email Service endpoint
`https://apps.webstudio.is/v1/preview-send` with server-side
`TRPC_SERVER_API_TOKEN`. The shared Email Service Worker remains
deployed at version `8769175b-15d2-4c09-a312-b78dc93fd2f3`; this PR did
not deploy or change it. The named staging Preview was deleted and its
former URL returns 404; staging published-site Workers use the canonical
Worker through the private service binding. An authenticated malformed
production Preview request returned `400 invalid_request` / `Invalid
email fields` before send. This proves only authentication and
validation, not successful submission or delivery. Staging
published-Form delivery is verified in Batch 7; limiter verification is
tracked in companion SaaS PR #666. A separate direct Email Service test
delivery was confirmed received; no email was sent by the
malformed-request preflight.

- [x] Enforce Cloudflare's 5 MiB **total encoded message** limit and
32-attachment cap for ordinary outbound email, accounting for base64
expansion; report provider quota, suppression, sender, size, and count
errors without claiming delivery. These email limits are separate from
the Form's 25 MiB incoming upload limit and Webstudio's five
team-delivery preflight. Local Builder preflight/provider-fake tests and
the companion SaaS Worker tests cover the limits and stable error
mapping; staging published-Form delivery is verified in Batch 7.

- [x] Test the local generated-site private-service contract with
provider fakes for recipients, Reply-To, optional Sender display name,
body, attachments, confirmation timing, partial failures, quota/limit
errors, and zero sends for failed preflight
(`packages/sdk/src/managed-form-email.test.ts`,
`packages/cli/src/prebuild.test.ts`; `7507c3fbf7`, `ab04be99d4`,
`7c950eecec`).

#### Acceptance criteria

- Staging verification must prove the selected private call path works
for a Workers for Platforms published site; the central Worker alone
owns `send_email`, and a submitted Form never receives provider
credentials or direct sending capability.
- A Cloud published Form delivers owner mail and the optional
confirmation with the configured envelope and content; 5
MiB/32-attachment violations and provider failures produce clear
`errors`. HTTP siblings retain the existing partial-failure semantics.
- The Email Service contract is for the new Form only. Existing Webhook
Forms do not use this Email Service as part of this feature; no legacy
Email Service compatibility or migration is included.

### Acceptance criteria

- A Cloud Email Resource sends the configured plain-text subject and
body from Webstudio's sending address with the configured display name,
with every submitted file attached under its original filename and MIME
type, or returns an explicit size/count error.
- More than five total team-recipient deliveries across Email Resources
rejects the whole submission before any destination runs; duplicate
addresses count again.
- A visitor receipt is a normal Email Resource explicitly selected in
Actions and addressed to the submitted visitor email field. It runs in
parallel with the other selected Actions, with no separate Form-level
toggle or email-field selector. Its Resource body is empty by default;
the Email Service always prepends the fixed platform receipt and
published site URL before the Resource body. The Resource body uses the
normal editor and full existing expression/binding support. A failed
visitor Email Resource appears in `errors` but is nonfatal to the
aggregate Form result.
- Resolved owner and confirmation subjects are strings without CR or LF.
An invalid subject, including one produced from visitor data, is
rejected before the email provider is called; the provider fake records
no send.
- Provider integration checks exercise the central Email Worker
request/response contract. Mocked Builder delivery alone does not
satisfy this gate.
- Confirmation failure appears in `errors` while the aggregate
submission remains successful; environments without Cloud email do not
silently claim delivery.

## Batch 5a — Keep separate submissions in separate email threads
(#5018)

Site owners should see each form submission as a separate email
conversation, including when several visitors submit the same form close
together.

- [x] Append a short, unique submission reference to each new Form
owner-notification subject, keeping the configured subject text.
Generate it once per submission and reuse it for that submission's
delivery retries; submissions in the same second get different
references. At `52fcec3640`, SDK tests cover default/custom subjects,
two submissions at one mocked time, retry stability, empty/overlong
preflight with zero HTTP/email sends, and the 979-character boundary;
Form and Project Emails docs describe the suffix. Batch 7 verifies that
separate submissions create separate Gmail conversations.
- [x] Apply per-submission subject references to new Form owner
notifications (`52fcec3640`).
- [x] Add local regressions for new Form default/custom subjects,
same-time identical submissions, stable retry references, and
subject-length preflight (`managed-form-email.test.ts`). Document the
suffix in the new Form and Project Emails docs.

### Acceptance criteria

- Two separate submissions of the same form appear as separate
conversations in Gmail with conversation view enabled.
- Both default and custom subjects keep their configured text and
include a different reference for each submission.
- Retrying delivery within one submission keeps its reference. This does
not add delivery deduplication or submission storage.
- This submission-reference behavior applies to new Form owner
notifications only; it does not add delivery deduplication or submission
storage.

## Batch 6 — Parallel delivery and Form feedback

- [x] Resolve dependency Resources needed for bindings, preflight every
selected primary destination’s body format and deterministic URL
parse/protocol/credentials/denied-hostname policy before dispatching any
selected primary destination, then start selected primary destinations
in parallel. Dependency Resources may make outbound requests during
resolution. DNS/public-IP pinning and redirect checks remain in
protected transport at each request hop; other transport failures can
occur after a sibling dispatches. Overall success requires all primary
destinations to succeed.
- [x] Local deterministic group preflight (`e9b72d5d78`, `8bf4f4c8bf`):
red-before generated actions in Remix and React Router prove a dependent
JSON+File body or a denied selected URL blocks all selected POSTs; SDK
policy tests cover allowed URLs and denied scheme, credentials, and host
cases. Nonselected dependencies may run once to resolve bindings.
Provider and ingress behavior are covered by service tests; staging
verification is recorded in Batch 7 below.
- [x] Until Cloud email delivery is integrated, reject any selected
Email Resource or reachable Email dependency before dispatching an HTTP
sibling. Return an explicit unsupported-delivery error without claiming
success.
- [x] Retry only a failed or timed-out destination once within that
submission, including non-2xx responses. Never resend a known success
within the same submission. A new browser submission starts over; keep
no delivery history or cross-submission deduplication.
- [x] Keep aggregate HTTP status as transport metadata only; expose no
`status` variable. Bind each Resource's final status code and response
body through ordered `results` and `errors` arrays. Expose no response
headers.
- [x] Redirect only after overall success when configured. Render the
initial, success, and error states in the inserted Form template.
- [x] Fix #6487 feedback auto-scroll regression: success and error
feedback now scrolls into the viewport only when needed, uses instant
behavior for reduced motion, and success redirect skips scrolling.
MCP-authored generated-Preview tests assert actual viewport position for
off-screen feedback, no movement for visible feedback, partial failure
scrolling, and no scroll before redirect; the full serial MCP E2E suite
passes (36/36 including setup).
- [x] Copy the existing Webhook Form spam protection into the new Form's
managed submission path: generate the hidden browser field, validate it
on the server before delivery, preserve the Brave handling, and remove
internal fields before sending to Resources or email.

**Email Service rate-limit checkpoint:** The pushed SaaS code uses
Cloudflare's native Rate Limiting binding only on email sends: 50
recipient checks per project UUID per Cloudflare location per 60
seconds. Each recipient consumes a check; over-limit sends return 429
before provider delivery. Preview and published sends carry the trusted
project UUID. This is approximate per location, with no Durable Object,
SQL storage, or account-wide quota. The 60-attempt direct Worker
diagnostic and isolated non-production check are tracked in companion
SaaS PR #666; no live-user Form submission is part of this Builder PR.
- [x] Locally test concurrent starts, retries, timeouts, partial
success, results and errors bindings, redirect, and feedback scrolling
in both generated adapters and browser components.
- [x] Local new-Form behavior: generated Router and Remix adapters test
concurrent selected starts, one retry after non-2xx/network/timeout
failure, final partial-success `results`/`errors`, and no replay of
successful siblings or dependencies
(`packages/cli/src/prebuild.test.ts`). Builder insertion tests verify
`results` and `errors` bindings and confirm aggregate `status` is not
exposed as a variable
(`apps/builder/app/shared/instance-utils/insert.test.tsx`); browser
tests cover success-only redirect and visible/offscreen feedback for the
new Form.

### Acceptance criteria

- Primary destinations begin in parallel. Each failed or timed-out
destination gets one retry within the same submission; known successes
are not resent, and overall success requires every primary destination.
- Ordered `results` and `errors` expose each Action Resource's
`resourceId` and `resourceName`, final status code, and response body to
bindings, without response headers. Both arrays preserve configured
Action order even when responses finish out of order. Aggregate HTTP
status remains transport metadata and is not exposed as a Form variable.
- Redirect occurs only after overall success, without scrolling to
inline feedback first. Otherwise the correct feedback state renders and
scrolls into view only when outside the viewport. Already-visible
feedback does not move the page, and animated scrolling respects reduced
motion. This applies to the new Form.
- New Form submissions use the adapted hidden browser check: valid
browser and Brave submissions pass; missing, malformed, or expired
evidence stops delivery before any destination runs; internal bot fields
never reach Resources or email.
- The Email Service code returns 429 for recipient checks over the
native per-project-UUID, per-location 50-per-60-second limit before
provider delivery. HTTP/Webhook Actions and webhook-only Forms are not
throttled by it. The 60-request direct Worker diagnostic and webhook
control are tracked in companion SaaS PR #666; no production Form
submission is part of this Builder PR.

## Batch 6a — Legacy-only work excluded from this feature

### Acceptance criteria

- The new Form accepts a fresh valid submission after an earlier failed
attempt without stale bot data.
- No legacy compatibility path is added to the SaaS Email Service.

## Batch 6b — Shared submission runtime for the new Form (related to
#4093)

Use shared new-Form submission behavior across supported hosting
runtimes while keeping page data current after a submission. This batch
does not complete #4093's remaining legacy Webhook Form work.

- [x] Move new Form submission, pending/error/success handling, and
response handling into shared code that does not require Remix or React
Router hooks or their form components. Generated hosting adapters call
the shared managed-Form handler; existing Webhook Forms keep their
original behavior.
- [x] Local new-Form lifecycle: router-free Form submission uses shared
`submitFormData`; generated Router and Remix adapters supply the server
request and page-data refresh behavior. Legacy compatibility adapters
and lifecycle changes are not included.
- [x] Submit through a normal HTTP endpoint with a defined JSON response
and small Router/Remix request and page-data-refresh adapters. Keep
current HTTP Resource credentials, validation, bot checks, and
destination protection on the server.
- [x] Local managed-Form route: generated same-origin `/__ws-form` POST
returns structured JSON for new Form submissions in compiled Remix and
React Router handlers; route coverage includes root, nested, and dynamic
pages, repeated multipart fields/files, bot rejection, and Resource
results. Staging Cloud email delivery is verified in Batch 7; the Email
Service rate-limit verification is tracked in companion SaaS PR #666.
- [x] Integrate the Cloud `EMAIL_SERVICE` adapter for new Email
Resources into the generated server action, with provider-fake response
and preflight tests. The Email Service per-site rate limit is tracked
separately below.
- [x] Replace the automatic page-data refresh currently supplied by
Remix. After a successful submission changes data, refresh the current
page's Resources without a full-page reload. Handle navigation during
submission and refresh failures without resending a completed
submission.

- [x] Test the new Form's shared component without router context
against a test HTTP endpoint, then test both hosting adapters. Cover
response bindings, page-data refresh, files, redirects, errors, and
retries.
- [x] Local browser and generated-route matrix: router-free Form tests
cover pending/results, files, and HTTP/network failures; generated
Router and Remix adapter tests cover retries, redirects, loader refresh,
navigation, and refresh failure without replaying POST. Compiled-handler
tests cover both adapters; release/staging verification is complete in
Batch 7.
- [x] Real router-free HTTP test (`679eb8e0c275`,
`packages/sdk-components-react/src/native-form-http.test.tsx`): the
shared new Form runs without a router provider in Chromium and sends
multipart POST to a local same-origin JSON endpoint without mocking
`fetch`. It reports pending while the response is held, then success
with `results` and a later error with `errors`, without native
navigation. Release/staging verification is complete in Batch 7.
- [x] Page-data-refresh red-before/green-after proof: with the exact
`native-form-refresh.browser.test.tsx` files from `20989a2d64` placed
temporarily in detached pre-fix `41580dbe9c`, React Router and Remix
each failed 3/5 tests: successful submissions left displayed data at
`before`, and the refresh-failure path never ran its second loader call.
On PR head `679eb8e0c275`, both adapters pass 5/5. The temporary
checkout was restored cleanly; the red/green regression evidence is
recorded here.
- [x] Local new-Form regression tests cover pending/results, errors,
redirect behavior, selected destinations, retries, and page-data
refresh. Remove legacy Webhook-specific retry, feedback, lifecycle, and
converter claims; they are outside the PR scope.
- [x] Update the hosting and Form docs to explain the generated server
endpoint, dynamic hosting requirement, and static-export limitation. The
generated Cloud action calls the private `EMAIL_SERVICE` binding when
present. Staging published-Form delivery is verified in Batch 7.

### Acceptance criteria

- The shared submission component works without a Remix or React Router
provider; supported hosting adapters connect it to server delivery and
page-data refresh.
- A successful data-changing submission refreshes the displayed data
without reloading the whole page or sending the submission again.
- Resource response values remain available through the bindings from
Batch 6, with consistent success/error behavior across supported
runtimes.
- The generated new-Form submission path uses the shared handler;
existing CLI conversion and legacy submission behavior remain at their
pre-PR baseline except for the #5512/#3891 route/query binding fixes in
Batch 2a.
- Server protections and secret handling remain intact. Static exports
do not silently claim managed submission support.

## Batch 7 — New-Form integration, docs, and release gate

- [x] Mark only the legacy `Form` and `RemixForm` component metadata
deprecated and keep `NativeForm` as the sole Forms insert tile. Preserve
the old component IDs, registrations, templates, and supported settings
for saved instances (`820aed68ed`;
`apps/builder/app/shared/nano-states/components.test.tsx`, focused
Chromium 2/2).
- [x] Local file-input and HTTP upload segments: Builder
insertion/save/reopen retains name, required, accept, and multiple
settings (`apps/builder/app/shared/instance-utils/insert.test.tsx`);
browser tests cover required, optional, and multiple files
(`packages/sdk-components-react/src/native-form.browser.test.tsx`);
compiled Remix/React Router generated actions preserve repeated
multipart fields and original file names, MIME types, and bytes
(`packages/cli/src/prebuild.test.ts`, `3c5b72a`).
- [x] Partial published-site staging check: one controlled `/copy-1`
submission with unique test value `Staging E2E 2026-10-05` entered the
managed Form success state for the selected project-owner Email Resource
configured with subject `New form submission`. The exact wire HTTP
response and owner inbox receipt are not independently verified; the
user is checking that inbox. This does not close the full
multi-destination, file, confirmation, coverage.
- [x] Update Form, Resource, Project Emails, and hosting docs for File
Input settings, HTTP uploads and limits, visitor-addressed Email
Resource with mandatory confirmation preamble/site URL and optional
body, and plain HTML forms using Element with `tag=form`.
- [x] Document the current managed Form's combined 25 MiB upload-request
limit, multiple-file failure guidance, and separate HTTP Resource body
limit (`33b2c7eab9`); Email provider attachment limits are documented in
the Email Service README, and published staging delivery is verified in
Batch 7.
- [x] Document local Resource selection/scope and Auto/JSON/multipart
upload behavior, plus Project Emails Sender, recipient, owner-body,
inheritance, and visitor Email Resource settings (`b9dbb6ee55`,
`7507c3fbf7`). Form, Project Emails, and self-hosting docs now describe
conditional Cloud `EMAIL_SERVICE` delivery, explicit missing-service
failure, and self-hosted integration requirements (`61fcf3f3d5`);
published staging behavior remains unverified.
- [x] Document Cloud Email attachment count and encoded content/request
limits in Form docs (`61fcf3f3d5`).
- [x] Document provider/quota errors and the Cloud email hosting
requirement. Builder Form, Project Emails, and self-hosting docs cover
new-Form visitor behavior and hosting limits. Sending-domain setup and
companion SaaS deployment are tracked in the companion SaaS PR.
- [x] Refresh the current bundle-version metadata in all eight static
project fixtures and synced user metadata in seven;
`packages/protocol/src/fixtures.test.ts` passes 17/17 locally and
Linux/Windows fixture CI both pass on head `70a2091c69`.
- [x] Complete relevant local checks on current PR work. Focused tests,
typecheck, lint, formatting, and diff checks pass locally; full GitHub
CI passes on `84f24e8d12`.
- [x] Reviewed each new-Form issue row against current code/tests; no
additional legacy compatibility beyond the explicitly tracked
#5512/#3891 route/query fixes is a closure condition. Evidence: #3023
file and attachment checks in
`packages/sdk/src/managed-form-email.test.ts` and
`packages/cli/src/prebuild.test.ts`; #5512 and #3891 page parameters and
all query values in `packages/cli/src/prebuild.test.ts`; #5432 repeated
multipart values/files in the same generated-route suite; #5499 parallel
destinations and five-recipient preflight in
`packages/sdk/src/managed-form-handler.test.ts`,
`managed-form-resources-generator.test.ts`, and
`managed-form-submission.test.ts`; #3530 redirect behavior in
`packages/sdk-components-react/src/native-form.browser.test.tsx`; #5428
trusted browser info headers in `packages/cli/src/prebuild.test.ts`;
#5658 sender/reply-to validation in
`packages/sdk/src/managed-form-email.test.ts` and the companion SaaS
Worker tests; #6487 feedback scrolling in
`packages/sdk-components-react/src/form-feedback-scroll.browser.test.tsx`;
#4414 and #4385 project defaults, overrides, and recipient isolation in
`packages/sdk/src/email-resource.test.ts` and
`apps/builder/app/builder/features/settings-panel/resource-panel.test.ts`;
#5018 unique submission references and retry behavior in
`packages/sdk/src/managed-form-submission.ts` and
`managed-form-email.test.ts`. These are merge-time issue mappings, not
production delivery evidence.

### Acceptance criteria

- The insert menu offers one new Form. Deprecated old components and
their migration are outside acceptance; no legacy compatibility path is
added.
- Staging end-to-end coverage exercises an empty Form blocked from
navigation and a configured Form submitting to its Resource
destinations, plus two HTTP Resources, two Email Resources, files,
confirmation, and partial failure through Builder → publish → submit.
- Form, Resource, Project Emails, and hosting docs match the released
behavior, including the Cloud email requirement. Generated contracts,
focused checks, full CI, and staging tests pass before the PR is ready.

## Batch 8 — Submit current-draft Forms from Builder Preview

- [x] Add an authenticated Builder server endpoint for Preview
submissions. It checks the Builder session and exact project build
permission before effects; route tests cover authorized and rejected
requests.
- [x] Load current draft Form configuration and invoke the shared SDK
runtime handler without a prior publish or draft/published contract
comparison; Preview route and graph tests cover changed drafts.
- [x] Build the draft Resource graph with publish-equivalent scope,
dependency, and defaults rules. Reuse the existing
`evaluateExpressionSync` implementation for supported expressions; do
not add QuickJS, WASM, AST, or another expression engine. Focused graph
and expression tests cover parity.
- [x] Reuse the shared SDK managed-form handler in Builder Preview and
generated published-site routes. Their request, auth, and configuration
entry points remain runtime-specific; SDK and generated-route tests
cover both paths.
- [x] Execute HTTP Resource Actions from the Builder server in Preview,
and from the published-site Worker after publish. The Email Service
handles email only; Preview route tests assert the outbound HTTP
boundary.
- [x] Route Preview Email Resources server-to-server through the Email
Service with a server-only credential; published-site Workers use the
private `EMAIL_SERVICE` binding. Builder checks user and project
permission first; tests cover the Email Service call contract and
rejected auth.
- [x] Removed the unapproved Preview warning that submissions send real
emails and webhook requests; new user-facing warning copy requires
explicit approval.
- [x] Node tests execute the shared handler locally with a stubbed Email
Service boundary, without Cloudflare infrastructure. Staging
published-Form Email delivery is verified in Batch 7; the production
Worker limiter check is tracked in companion SaaS PR #666.
- [x] Keep a permanent Builder Preview transport Playwright E2E that
submits a current draft through the Preview backend and verifies the
response without publishing or triggering email/webhook side effects
(`apps/builder/e2e/tests/preview-managed-form.[shard-2].e2e.ts`; focused
2/2).
- [x] Preview converts rejected `onManagedSubmit` callbacks into a
structured 500 failure, clears stale result and pending state, and shows
the current error. Browser regression covers a prior structured failure
followed by a rejected callback
(`packages/sdk-components-react/src/native-form.browser.test.tsx`). The
new Form also cancels native submission when its `onSubmit` callback
throws; a Chromium browser regression clicks a submitter with
`formAction`/`formMethod` overrides and verifies cancellation, no
Resource dispatch, and visible failure (`28f7a93eed`).

### Acceptance criteria

- A Form in an unpublished project can be submitted from Builder Preview
without publishing first.
- The Preview endpoint rejects unauthenticated users and users without
edit access to that project before any HTTP request or email send
occurs.
- Preview uses the current draft. Changes to controls, Actions, Resource
dependencies, effective email settings, visitor-addressed Email
Resources, or redirects can be tested immediately without republishing
or a published-contract comparison.
- Draft expression results match published Resource evaluation for
supported syntax using the existing `evaluateExpressionSync`
implementation; no second expression engine is introduced.
- HTTP Resource requests go directly from the Builder server to their
configured destinations. Email Resource requests go through the central
Email Service Worker, which rejects requests without the server
credential; that credential never appears in browser traffic.
- Results, errors, uploads, response bindings, feedback, and redirects
match published submission behavior while keeping the Builder open.
- The generated published-site Worker continues to use the same shared
handler and public visitor submission path, and calls Email Service
through `EMAIL_SERVICE`.
- Local Node E2E tests exercise the shared handler and Builder Preview
authorization without Cloudflare; a separate integration check verifies
the real Email Service contract.

## Production release boundary

**The production Email Service Worker was deployed at version
`8769175b-15d2-4c09-a312-b78dc93fd2f3` under the user's explicit request
to update the code and Worker to use `TRPC_SERVER_API_TOKEN`. An
authenticated malformed validation request returned `400
invalid_request` before send; that request sent no email.** This Builder
PR makes no deployment to the live site; live-user Form submissions are
outside its verification scope.

## Boundaries and known tradeoffs

- No old-component migration, submission storage or history,
account-wide email quota feature, CC/BCC, custom From address or
customer sending-domain verification, HTML email, preview text, or
separate branding editor. Builder Preview submission is included in
Batch 8 and runs against the current draft without requiring
publication; it is a real submission, not a separate email test-send
feature. Cloudflare account sending quotas still govern delivery;
migrating Plunk authentication or other Plunk operations is separate
follow-up work.
- The Discord requests for an explicit CAPTCHA challenge, direct Google
Sheets connection, multi-thumb/vertical slider, and an exact submission
copy to an unverified visitor are not covered here. A visitor-addressed
Email Resource always gets the fixed platform preamble and site URL; its
optional builder-configured body may use normal Resource bindings.
- A timeout retry can duplicate a delivery that succeeded remotely. A
visitor-addressed Email Resource can send to an unverified submitted
address; the native Email Service limit of 50 recipient checks per
project UUID per Cloudflare location per minute can reject legitimate
local bursts; it is approximate and not a global cap.
- The five team-delivery cap is a server preflight across the whole
Form; it is intentionally not calculated across independent Resources in
the Builder.
- Project defaults apply site-wide. Form-only expressions resolve only
in Resources scoped inside that Form.

## Additional Builder and Resource behavior

### Builder UI

- [x] Add the `formState` bullet to the Action tooltip after the exact
user-facing description is approved; verify it with the focused tooltip
test. The exact wording was approved; covered by focused Action tooltip
tests.
> Sends each form submission to all selected destinations at the same
time.
  > - formData — submitted fields from this Form.
  > - browserInfo — visitor details.
  > - formState — current Form state: initial, success, or error.
  > - results — each action’s response, in order.
  > - errors — failed actions and their messages.
- [x] In the Variables list and Edit variable preview, show
server-provided `browserInfo` after an authenticated Builder Preview
submission when available. Use only trusted `cf-connecting-ip`, ignore
spoofed `x-forwarded-for`, and sanitize Referer by removing query and
fragment before exposing it. Keep `previewBrowserInfo` private to
Builder memory and strip it before Canvas pubsub. Route, bridge,
Variables list, and Edit variable preview tests cover these paths;
focused preview tests pass (2/2) and bridge tests pass (7/7). Published
Form behavior stays unchanged.
- [x] Recognize supported Chromium browsers without requiring
`window.chrome`; user-agent detection and unsupported-browser regression
coverage are committed.
- [x] Add the approved “Clear all” button below multiple visible toasts
and dismiss the stack; shared toast implementation and browser
regression are committed.

- [x] Remove the background from the maximize button in code and
expression editors; keep the icon button transparent, consistent with
other editor controls. `code-editor-base.browser.test.tsx` verifies
transparent hover styling.

- [x] Implement separate tooltips for the Form variables `formData`,
`browserInfo`, `formState`, `results`, and `errors`; exact wording was
approved on 2026-10-08, and `variables-section.test.tsx` verifies the
displayed descriptions.

- [x] Add a description to the Action label tooltip and show a yellow
warning triangle with “Add at least one action” when the Action list is
empty. The warning disappears once an Action is added; covered by the
Form Action control browser test.

- [x] Reset the Form Preview runtime state to `initial` when leaving
Preview, so the Builder returns from success/error feedback to the
editable Form state without changing saved bindings or published
behavior. Add regression tests.

- [x] Route every managed Form submission error through the user-styled
Error Message instance. Make its message dynamic from the submission
error result, remove static fallback text and raw React alerts, and
cover validation, partial Action failure, and service errors.

- [x] When a Form, Form content, Success Message, or Error Message
instance is selected on the canvas, show that selected instance in
Builder regardless of its bound `show` value. This is an editor
selection override only; preserve the saved binding and runtime
behavior. Add regression tests for each state.
- [x] Add the approved description “Sends each form submission to all
selected destinations at the same time” and a multiline list for
`formData`, `browserInfo`, `formState`, `results`, and `errors` to the
Action label tooltip; use lowercase “action” in descriptions. Remove the
aggregate `status` variable; Form state remains
`initial`/`success`/`error`, and each Action’s HTTP status stays in its
result/error entry. Retain the approved “Add at least one action”
warning when no Action is selected. The Action reset button says
“Reset.” Focused insertion and Action UI tests cover these behaviors.

- [x] The Action plus-button tooltip says “Add a resource to submit this
Form”; the focused Form Action control browser test covers it.

- [x] Rename the Form’s component prop from `submission` to `action`,
matching the singular **Action** control. Store selected Actions as an
ordered array of Resource references with enabled state. Execute enabled
requests in parallel while preserving Action order in `results` and
`errors`. Update generated metadata, runtime handling, and tests; do not
add legacy compatibility.

- [x] Add Delete, Copy, and Paste to each variable row menu and its
right-click context menu. Within Variables, right-click anywhere allows
Paste; target-specific commands are disabled without a variable row.
Remove the Variables section header menu. The Edit variable dialog menu
has Delete, Copy, and Refresh only; remove its redundant quick-copy
button and do not offer Paste there. Serialize definitions as versioned,
namespaced JSON; omit internal IDs, create fresh IDs on paste, preserve
and remap expression references, and report unresolved references. Base
menu and transfer tests pass.

- [x] Rename user-facing Builder UI section and control labels from
`Data variables` to `Variables`; retain `CSS variables` for clarity.
Update UI tests.

- [x] Give variable labels a tooltip that shows defining scope,
type/value-kind details, and Delete with its shortcut. Option-click
deletes the local variable; deleting a shadow reveals its ancestor. UI
tests cover the tooltip and Option-click deletion.
- [x] Clicking the rendered “Value comes from” source label navigates to
and focuses its defining instance. `variables-section.test.tsx`
exercises the real ancestor “Body” source label and Global root label;
the full focused file passes 9/9.
- [x] Label a Global Root user variable source as “Global root,” not
“System,” and keep the source label clickable to navigate to and focus
its definition. `variables-section.test.tsx` verifies the “Global root”
label, absence of “System,” and source navigation.
- [x] Fix the verified source-label behavior defect: clicking “Value
comes from” must reliably focus its defining Variables row after
ancestor or Global root navigation. Regression tests pass both
standalone and in-suite: `variables-section.test.tsx` passes 12/12, and
isolated ancestor/Global root navigation-focus cases pass 3/3 each.

- [x] Prevent deletion of the managed Form’s required `formState`,
`results`, and `errors` variables by stable identity in the Builder UI,
including after renaming, through Variables row menus, the Edit variable
menu, right-click context menus, and Option-click; ordinary user
variables remain deletable. `variable-menu.test.tsx` covers the menu
paths and ordinary deletion; focused suite passes 21/21. The
required-variable rule is enforced in both the Variables UI and the
mutation/domain layer.

- [x] Show a yellow warning triangle only when a variable name matches
an ancestor; allow the child-scope name. Tests cover an existing shadow
and an ancestor rename.

- [x] Keep the variable row highlighted while its Edit variable dialog
is open; use the shared list-row open state and cover it with a
regression test.

- [x] Use the shared warning color token for variable-shadow triangles
in both the Variables list and Edit variable dialog; the Builder UI test
verifies the token.

- [x] Reject duplicate Resource variable names on the same instance
while allowing a nested scope to shadow a parent name; add validation
and regression tests.

- [x] Use sentence case for the Form setting label: `Success redirect`.

- [x] Expose Form-scoped runtime values as inspectable JSON in Builder
Preview. `formData` reflects the current named controls and values
before submission, including empty values; `browserInfo` shows its safe
context values. Add focused UI and runtime tests.

- [x] Add `resourceName` alongside `resourceId` in each ordered
result/error and relevant inspection entry; verify naming, partial
failure, retries, and bindings without exposing secrets.

- [x] Independently rechecked #3891 against the implemented contract:
`system.search` returns a string for one value and an ordered array for
repeated query values. `packages/sdk/src/system-search.ts` and its
regressions cover repeated, empty, comma-containing, and encoded values;
Batch 2a retains the generated-route and documentation evidence.

- [x] Verify that a selected Email Resource defined on the Form, an
ancestor, or global scope uses the existing generated submitted-fields
default body when both its Resource body and Project Emails body are
unset. Preserve explicit Resource/Project body overrides, including an
explicitly empty Resource body, Visitor receipt behavior, and rejection
of explicit out-of-scope `formData` bindings. Draft and published graph
tests cover all three scopes and both override types in
`managed-form-resources-generator.test.ts` and
`managed-form-draft-graph.test.ts`; focused SDK tests pass (73 tests).

### Resource editor

- [x] In Project Settings → Emails, show all long explanations in the
existing info tooltips beside their related controls, preserving the
exact existing copy. Specifically verify the Recipients and Owner
plain-text body explanations; `section-emails.test.tsx` currently covers
tooltip content and keyboard access.

- [x] Restore the approved attachment behavior sentence in the Project
Settings → Emails documentation, in the Visitor email paragraph only:
“When a Form includes file inputs, submitted files are attached to the
outgoing Email Resource message by default. Turn off ‘Attach submitted
files’ to omit them.” Do not add this text to the settings UI. Added in
`c96fb7c409`; `pnpm check:generated-docs` and `git diff --check` pass.

- [x] Replace the outdated Visitor attachment statement in the Form
guide with the same approved sentence used in Project Settings
documentation: “When a Form includes file inputs, submitted files are
attached to the outgoing Email Resource message by default. Turn off
‘Attach submitted files’ to omit them.” Added in `40dd8c4af3`; `pnpm
check:generated-docs` and `git diff --check` pass.
- [x] **Email Resource Type description:** The exact description was
approved, and `variable-popover-type.test.tsx` asserts the Email option
displays “Send a plain-text email through Webstudio Cloud when a Form is
submitted.” Focused type-selector suite passes 7/7; Builder typecheck
passes.
- [x] **Method dropdown copy approval:** Exact copy is approved and
tested: GET “Read data from a server.”; POST “Send data to create or
process something.”; PUT “Replace data on a server.”; DELETE “Delete
data from a server.” Keep the existing Form-submission note with POST;
focused Resource editor tests verify all four descriptions and the POST
note.
- [x] Keep Email Resource field labels as `Sender`, `Recipients`,
`Subject`, and `Body`; use the existing binding control and Expression
Editor for supported values, and show validation errors in the standard
input tooltip rather than below the field. `resource-panel.test.ts`
asserts each label appears exactly once, covers the binding controls and
Sender/Custom recipient Expression Editor save/unmount/remount/reopen,
and verifies validation errors appear in standard input tooltips; the
focused suite passes 30/30.
- [x] Give Email Resource recipient controls programmatic accessible
names by associating the existing visible “Recipients” label with its
selector and using existing text for the Custom recipient input and
Visitor email selector. Keep visible copy unchanged.
`resource-panel.test.ts` passes 32/32; Builder typecheck, changed-file
`oxlint --deny-warnings`, and `oxfmt --check` pass.
- [x] Remove the separate Project default reset button; switching away
from Custom recipients clears its value. Show the custom address input
directly below the mode selector and the Visitor field selector without
redundant field labels. `resource-panel.test.ts` covers literal and
bound recipient clearing when switching to Project and Visitor modes,
mode-specific controls, and no duplicate Recipients label; the focused
suite passes 30/30, including Sender and Custom recipient bindings
through the Expression Editor and save/unmount/remount/reopen.

- [x] Verify and test the REST and GraphQL type-option descriptions
against the approved wording: “A REST resource is a configuration for
secure data fetching.” and “A GraphQL resource is a configuration for
secure data fetching with GraphQL.” Preserve the existing “You can
safely use secrets in any field.” note. `variable-popover-type.test.tsx`
covers both descriptions.
- [x] **Visitor email field info tooltip:** Approved exact copy for the
info tooltip beside the Visitor email field selector: “Adds a note with
this site’s URL to help recipients identify where the message came from
and discourage spam.” Keep it visible only when Visitor email field is
selected; verify the text opens on hover and keyboard focus and closes
on blur in `resource-panel.test.ts`.
- [x] Match the Edit variable dialog menu trigger icon size to the other
header controls and make the menu’s minimum width about twice its
current width; `variable-menu.test.tsx` covers the header icon and 360px
minimum width.
- [x] Simplify Builder Email Resource preflight: remove duplicated
Worker-authoritative mailbox and attachment metadata policy checks;
retain a small pre-Base64 attachment size guard, subject safety, and
aggregate recipient protections. Tests verify early size rejection,
valid attachment delivery, and Worker rejection propagation.

- [x] Replace the superficial Headers and Search params label
info-tooltip descriptions with clear technical explanations of their
purpose; propose and obtain approval for exact user-facing copy before
implementation. The approved label info icons explain these sections; no
additional plus-button tooltips are needed. Exact wording approved;
covered by focused Resource editor tests.

- [x] **Recipient selector descriptions:** Add the approved descriptions
exactly: Project recipients — “Send to the addresses in Project
Settings, or to the account holder if none are set.”; Custom recipients
— “Send to the addresses entered below.”; Visitor email field — “Choose
a Form input to use as the recipient’s email address.” Verify copy and
visibility in `resource-panel.test.ts`.
- [x] **Move Visitor email guidance into its recipient option
description:** Removed the extra info icon next to the selected Visitor
email field input. The Recipients dropdown option now explains that the
confirmation email goes to the selected Form input address.
`resource-panel.test.ts` passes (41/41); formatting, lint, and diff
checks pass. Pushed as `a85c77308f`.

- [x] Put the Form POST-method note in Method dropdown option
descriptions instead of inline copy; keyboard and pointer behavior are
covered by the Resource editor tests.
- [x] **Format option descriptions:** Approved exact copy: label
`Format`; help below the control “Choose how to send the body.”; `auto`
— “Uses text/plain for text values, application/json for other values,
and multipart/form-data when files are included.”; `application/json` —
“Sends an object or array as JSON.”; `multipart/form-data` — “Sends
fields as form data, including files.” `resource-panel.test.ts` verifies
the descriptions, below-control help, standalone GET hiding, Form Action
GET visibility, and Body editor; the focused suite passes 34/34.
- [x] **Headers and Search params add-button tooltips:** Superseded by
the user's clarification: the approved info icons beside the Headers and
Search params labels explain those sections, so no additional tooltips
on the plus buttons are needed. The existing info-icon descriptions
remain covered by the focused Resource editor tests.
- [x] **Project Settings → Emails helper-text placement:** Move the long
inline explanations (including Recipients and Owner plain-text body
help) into adjacent info tooltips so the settings stay compact. Do not
add or rewrite user-facing copy without explicit approval; preserve
approved behavior and cover tooltip placement with focused tests.
- [x] **Shadowing warning tooltip copy:** Reverted the unapproved
proposed wording and retained the existing tooltip.
`variables-section.test.tsx` verifies the parent-scope shadow condition,
including an existing shadow and an ancestor rename; a unique name
removes the warning.
- [x] Add an info tooltip beside Cache max age explaining the response
cache lifetime in seconds. A focused Resource editor test verifies it.
- [x] Use the approved info icons beside the Headers and Search params
labels to explain those sections; no additional plus-button tooltips are
needed. Use Minus icons to remove individual rows. Focused Resource
editor tests cover the label info tooltips and row removal.
- [x] Keep the Body label and remove the Body content type selector.
Infer text/plain for string bodies and application/json for objects,
arrays, numbers, and booleans; preserve automatic multipart handling for
files, explicit request-format validation, and useful editor/error
behavior.
- [x] Label the body-format dropdown Format and show the approved help
“Choose how to send the body.” below it. Use the effective method: hide
Body and Format for a standalone GET Resource; a GET-configured Resource
selected as a Form Action is effectively POST and keeps both controls
visible. Focused editor tests verify the help placement, visibility, and
selected body format.
- [x] Show Response, Request, and Diagnostics tabs for HTTP Resources,
with Response first and selected by default. Capture the actual outgoing
method, URL, headers, and body plus response status/status text,
headers, final URL when available, and body from the latest Form Preview
submission, including retry attempts. `request-inspector.test.tsx`
verifies the order and default selection, including the captured numeric
response status and actual response body for both HTTP and Email
exchanges (focused suite 7/7); route and inspector tests verify captured
exchange data, no replay or substitution from current config, and
authenticated Preview-only, no-store, ephemeral, bounded, redacted
capture. Files show metadata instead of bytes. Email inspection shows
the captured transport request and actual HTTP response, with
credentials and encoded attachment bytes redacted; the logical delivery
outcome remains separate for Form failure handling. Published staging
submission and attachment delivery are verified in Batch 7.

- [x] Classify Email inspection exchanges by Resource kind, never URL
alone; focused sanitizer and inspector tests verify that an ordinary
HTTP Resource targeting the Email Service URL keeps normal request-body
redaction.
- [x] Preserve actual Email Service response headers in the Email
inspection Response view; `resource-loader.test.ts` verifies transport
capture and `preview-form-inspection.server.test.ts` verifies safe
headers reach the inspection view.
- [x] Preserve the actual Email Service HTTP response body/status
separately from the logical Email delivery result, so provider-level
failures remain Form failures even when HTTP returns 200. Read the
response body once so inspection and delivery validation share the same
parse; keep captured data bounded. Add regressions for malformed success
and non-JSON error responses. Single response read, bounded inspection
snapshot, provider body and logical outcome regressions; SDK tests pass.

- [x] Keep the Variables panel context menu scoped to the panel:
right-clicking a variable row targets that row, blank panel space allows
Paste, and right-clicking inside the Edit variable dialog does not open
the panel menu. The dialog menu offers Delete, Copy, and Refresh only;
`variable-menu.test.tsx` covers row, blank-space, and dialog
context-menu behavior.
- [x] Keep Email Resource attachments enabled by default. The default
contact Form’s owner Action keeps attachments enabled, while its visitor
confirmation explicitly opts out because it does not include the
submitted file. `managed-form-email.test.ts`, `resource-panel.test.ts`,
and the default contact Form E2E cover defaults and opt-out.

- [x] Support bindings for Email Resource Sender and Custom recipients
using the existing binding/Expression Editor pattern; evaluate and
validate resolved mailbox values before dispatch.
`resource-panel.test.ts` verifies Sender and Custom recipient bindings
through the Expression Editor and save/unmount/remount/reopen (30/30).
`email-resource.test.ts` verifies resolution and rejects empty,
non-string, and invalid values; `managed-form-handler.test.ts` verifies
invalid bound values are rejected before Resource fetch or email send
(35/35 combined SDK tests).
- [x] Memoize Email Resource recipient expression scope inputs
(`recipientScope` and aliases) so editing a recipient value does not
restart asynchronous expression evaluation on every render; add focused
regression coverage. Unrelated Resource edit regression passes;
`resource-panel.test.ts` 34/34.
- [x] Make all Email binding tests use CodeMirror’s platform-aware Mod
shortcut (Meta on macOS, Control elsewhere), including Sender/Custom
recipient round-trip and Project-mode bound-recipient clearing, so they
pass Ubuntu CI. `resource-panel.test.ts` contains no hard-coded
Meta/Control keyboard chords and passes the full focused suite (30/30).
- [x] Ensure generated server modules import Email binding helpers only
once when both regular Resources and managed Forms use Sender or Custom
recipients bindings; generated-site resource-only and combined-module
tests in `packages/cli/src/prebuild.test.ts` assert one helper import
(2/2), and the CLI typecheck passes.
- [x] Ensure generated modules for generic (non-managed) Email Resources
using `senderExpression` or `recipientsExpression` import the runtime
resolver helpers. `packages/cli/src/prebuild.test.ts` verifies one
helper import and typechecks a mixed generated site with page-level and
managed-Form Email bindings, plus a page-level-only site; both focused
cases pass (2/2).
- [x] Enforce the five-recipient total before dispatch for Email
Resources with Sender or Custom recipients bindings. Count known/literal
recipients even when the Email Resource depends on another Resource;
reject recipient expressions whose count depends on a Resource output
before any send. Preserve Form-variable bindings.
`managed-form-handler.test.ts` covers a resolved six-mailbox binding and
verifies rejection before HTTP fetch or email send; existing dependency
tests cover Resource-output counts.
- [x] Prevent or support Email recipient expressions that depend on
another Resource. The editor currently accepts these expressions, but
managed-submission preflight rejects them; align editor validation and
runtime behavior, with focused regressions. Editor binding scope now
excludes Resource outputs; server preflight remains fail-closed; focused
tests and Builder typecheck pass.
- [x] Disallow Email recipient bindings that depend on another Resource
in the Builder editor, while keeping server preflight fail-closed.
Resolving dependencies before the recipient-limit check could trigger
arbitrary requests; add focused editor and preflight regressions. Editor
binding scope now excludes Resource outputs; server preflight remains
fail-closed; focused tests and Builder typecheck pass.
- [x] Fix Type and Recipients dropdowns in a narrow sidebar so each
dropdown panel matches its input trigger width, using Name as the
reference; focused tests cover Type, Recipients, and Method. Flattening
removes the separate Resource dropdown.
- [x] Flatten System resources into the single Type list: remove the
separate “System resource” category/dropdown and list Sitemap, Current
date, Assets, and Email alongside the other Type choices. When editing
an existing System Resource, changing between categories
(Sitemap/Current date/Assets ↔ Email) persists the selected type.
Preserve existing Assets Resources whose URL expressions use valid
non-JSON string-literal syntax; add a reopen regression in
`variable-popover-type.test.tsx`. Assets non-JSON URL expression reopen
regression passes; Builder popover tests pass.

- [x] Fix the Builder typecheck failures in `resource-panel.test.ts`
binding tests caused by nullable queried-button assertions, then rerun
and pass the Builder typecheck. Builder typecheck passes and
`resource-panel.test.ts` passes 30/30.
- [x] Add a generated published-route regression proving that an
unset/default Form Action body with an uploaded File selects multipart
automatically and preserves filename, MIME type, and bytes.
`packages/cli/src/prebuild.test.ts` runs the generated endpoint for both
defaults and React Router adapters; the focused test passes 2/2.
- [x] Add regression coverage that an ordinary Project/Custom Email
Resource with `includeAttachments` absent resolves default-on through
the Email Service payload. `packages/sdk/src/managed-form-email.test.ts`
covers both recipient modes and asserts attachment payloads; the focused
suite passes 29/29, and `pnpm oxfmt --check
packages/sdk/src/managed-form-email.test.ts` passes.

- [x] Resolve current changed-file lint findings (two `no-explicit-any`
findings in changed tests and one `react-hooks/exhaustive-deps` finding
in `variable-popover.tsx`), then rerun scoped lint. Changed-file `oxlint
--deny-warnings` passes on 50 TypeScript files; `oxfmt --check` passes
on all 48 matched changed files; Builder typecheck passes; focused
settings/variables suites pass 47/47.

- [x] Simplify `handleManagedFormSubmission` by removing the redundant
one-Visitor-Email validation and relying on the shared
`validateManagedFormRecipientLimit` check; add or retain focused
preflight regression coverage. Handler and submission suites pass 48
tests, and SDK typecheck passes.

## Additional Form and Builder behavior

- [x] **Use the existing upload icon for the File input component:** The
shared `UploadIcon` is used in the File Input template and asserted by
`core-templates.test.tsx`.

- [x] **Verify Success redirect in Builder Preview:** On successful
submission, keep navigation inside Preview for internal routes, resolve
relative URLs against the previewed page, and navigate the preview frame
for external URLs. Add end-to-end coverage for a matched internal route,
an unmatched route (which currently silently does nothing), and hash
navigation (which currently updates the hash without scrolling).
Preserve error feedback and never redirect after a failed action.
Matched internal, unmatched internal, and delayed hash target cases pass
in Preview E2E; failed actions retain error feedback and do not
redirect.

- [x] **Finish Email diagnostics loading:** The Email Resource
Diagnostics tab no longer remains pending without a request key; focused
regression coverage verifies the settled empty state.

- [x] **Separate variable editors by type:** The dialog composes focused
modules for HTTP, GraphQL, Email, Assets, Parameter, and scalar types;
shared controls remain neutral. Focused Builder tests and typecheck
pass.

## Issue checklist

Eleven issues below are intended to close when this PR merges; #5432 and
#4093 are related but remain open. Each closure row must be implemented
and verified first; keep remaining work unchecked.

| Issue | Required result before merge | Batch |
| --- | --- | --- |
| #3023 | Configure file inputs in the Builder; deliver single/multiple
files to HTTP destinations and Cloud email within documented limits. |
3, 5, 7 |
| #5512 | Current-page parameters work in new and legacy Form Resource
bindings, including after navigation. | 2a |
| #4093 | Related issue for the legacy Webhook Form; this PR implements
Resource Actions and response bindings in the new Form but does not
change legacy submission beyond the explicitly tracked #5512/#3891
route/query binding fixes, shared lifecycle, or CLI conversion behavior.
Keep #4093 open. | 2, 3, 6, 6b |
| #5432 | The new Form sends repeated field values as standard multipart
entries without losing selections. Legacy Webhook Form behavior remains
unchanged except for the separately tracked #5512/#3891 route/query
binding fixes; this PR does not close the original issue, and migration
is separate. | 2, 3 |
| #5499 | One submission can deliver to email and multiple HTTP
destinations together; document the ten-destination and
five-team-delivery limits. | 2, 5, 6 |
| #3530 | A successful submission follows the configured redirect;
failure does not redirect. | 6 |
| #5428 | A destination receives the trusted visitor IP, user agent, and
language through configured Resource headers, with setup documented. |
2, 7 |
| #5658 | Custom subject and Sender work as agreed, with provider-level
tests for From and Reply-To. | 4, 4a |
| #6487 | New Forms reveal off-screen feedback, leave visible feedback
alone, respect reduced motion, and do not scroll before redirecting. | 6
|
| #4414 | Editable name/reply address, subject, plain-text template, and
translated content work with project defaults and per-Resource
overrides. Webstudio remains the sender, as agreed. | 4, 4a, 5 |
| #4385 | Two forms in the same project can send to different configured
recipients without changing each other's delivery. | 4, 5 |
| #5018 | Separate new-Form submissions produce separate Gmail
conversations; retries retain the same submission reference. | 5a |
| #3891 | Every selected query value is available in new and legacy Form
Resource bindings through `system.search`, with a single value remaining
a string and repeated values becoming an ordered array. | 2a |

- [x] After PR #6530 merged (`a49a6769bd`), verified the new Form needs
no port: React Router and Remix use the same Form submit path, which
creates fresh `FormData` and calls `set` once for the bot field on each
request. `generates one fresh bot field for each managed submission`
passes (shared browser suite 7/7); Router managed Form tests pass 2/2,
Router refresh tests 7/7, and Remix refresh tests 5/5.

confirmed the canonical `TRPC_SERVER_API_TOKEN` is supplied from
Infisical in Preview and Production. Builder Preview now sends this
token to Email Service `/v1/preview-send`; the redundant
`EMAIL_SERVICE_PREVIEW_TOKEN` wiring is removed. Focused route tests
verify authorization, missing-token behavior, webhook-only behavior, and
redaction.

- [x] **Defer validation for a new Resource URL:** Untouched blank URLs
are not marked invalid until save; edited invalid values validate on
blur. Regression tests pass.

- [x] **Handle safe public Resource redirects:** Public GET/HEAD
redirects are revalidated and allowed without forwarding credentials;
unsafe destinations and cross-origin body requests remain blocked.
Protected-fetch tests pass.

## Form component identity correction (2026-10-11)
- [x] Keep component picker labels and compatibility behavior clear:
show the new component as **Form (Beta)**, and keep the existing
**Webhook Form** available in its current Data category through the next
release. Update the guide for the 10-Action limit and Navigation mode
when Actions are empty. Builder component-list and registry template
tests pass.

- [x] Use one canonical managed component identity, `Form`, for Resource
submission and Navigation mode. Keep `WebhookForm` only as the legacy
component through the next release, and keep generic `Element` with tag
`form` for native browser behavior. Update exports, metadata, templates,
adapters, migrations, docs, CLI/MCP discovery, and E2E identifiers;
verify saved projects migrate without changing legacy Webhook Forms.
Project migration tests pass (25/25), and the CLI prebuild suite
verifies saved bundles are migrated before rendering and endpoint
generation.

## Framework-neutral Form core (2026-10-11)
- [x] Move managed Form contracts, browser submission behavior, and
server delivery into SDK Form entries. Keep React hooks/rendering in the
React adapter and router refresh timing in the router adapter; preserve
compatibility exports. Builder and CLI consume the dedicated server
entry. StrictMode, cancellation, redirect fallback, and refresh-failure
behavior have regression tests. SDK build and published types,
SDK/React/router/CLI/Builder typechecks, focused SDK/React/router/CLI
tests, generated route tests, and the browser bundle boundary check
pass. Astra Medium reviewed the architecture and final diff; no
remaining findings.

## SDK package boundaries (2026-10-11)
- [x] Document each SDK package’s architectural role and dependency
constraints. Added root READMEs for `sdk`, `sdk-cli`, and
`sdk-components-registry`; clarified the existing React SDK, React
component, Radix, Router, Remix, and animation package READMEs.
Formatting and diff checks pass.

## Form submission lifecycle
- [x] **Handle rejected submissions when the controller refuses them:**
Consume abort-aware submission promises when a duplicate or disposed
Form submission is refused. Regression tests cover both paths; four
lifecycle tests, SDK typecheck, and diff checks pass.












## Unified Canvas selection reveal (2026-10-12)
- [x] Reduce selection reveal metadata and resolver ceremony while
preserving occurrence validation, owner/source boundaries, and focused
coverage. Replaced ten one-element rule arrays with one optional rule
each, removed the unused fallback field and redundant source union,
combined selector validation with path construction, and bounded the
source search. The optimization removes 24 production lines and 10 test
lines (net), with the shared resolver and derived override layer intact.
Focused Builder tests pass 66/66, Radix 20/20, registry 1/1; SDK, Radix,
registry, and Builder typechecks, scoped lint, formatting, and diff
checks pass. The nested Radix portal check uses a rendered harness
rather than the full Canvas. Independent Astra Medium re-review found no
correctness findings. Pushed commit
`5bc392d3788ef004f9a35c9a12d82dab6087053a`; `builder-pr/whr.staging` SHA
verified.
- [x] Replace duplicated Radix Navigator selection handlers with
declarative component metadata and one Builder-owned, occurrence-aware
selection override resolver. Native Select, HeadSlot, and
AnimateChildren hooks remain for their separate editor behavior.
- [x] Reveal selected `ws:show=false` instances and ancestors through
resolved prop overrides, including Form success/error feedback, while
preserving normal published rendering.
- [x] Resolve fixed `open` and effective item/tab `value` rules for
Dialog, Popover, Tooltip, Select, Collapsible, Tabs, Accordion, and
Navigation Menu. DialogOverlay retains its existing reveal behavior.
Preserve unrelated memory props and Preview behavior.
- [x] Verify resolver, lifecycle, nested Dialog portal mounting,
Collection occurrence isolation, authored expression updates, and Canvas
prop behavior. Local focused Builder suites pass 66/66; Radix 20/20;
registry 2/2. SDK, Radix, registry, and Builder typechecks, scoped lint,
formatting, and diff checks pass. Independent Astra Medium review
findings were fixed and rechecked. Pushed commit
`f8bb1078195e17704ed856c4334683584e983485`; `builder-pr/whr.staging` SHA
verified. These are local automated checks, not live UI verification.





### Remaining Navigator hook migration

- [x] Migrated every remaining Navigator hook consumer: native
Option/Select and tagged `ws:element` use effective option values and
HTML text fallback; HeadSlot uses a fixed self override; AnimateChildren
uses a fixed override only for its exact selection.
- [x] Removed Navigator hook implementations,
`Hook`/`HookContext`/`InstanceData`/`InstancePath` and
`getClosestInstance`, hook subscriptions and store, library
registration, package hook entrypoints/build inputs, and the stale
catalog hook capability field.
- [x] Added behavior coverage for evaluated/bound native values,
empty/zero values, HTML whitespace/NBSP fallback, repeated occurrences,
nearest owner, stale selection, HeadSlot rendering, exact animation
selection, Preview, deselection, and no saved-prop/memory mutation.
Existing Radix runtime index behavior remains covered.
- [x] Completed Astra Medium self-review and independent Astra High
review. Fixed the High review finding: native fallback values must
preserve non-ASCII whitespace.
- [x] Final repository search found no remaining Navigator hook
consumers or registrations.

Validation:

- `pnpm --filter @webstudio-is/builder exec vitest run

- `pnpm exec oxlint --deny-warnings` on all changed TypeScript files,
`pnpm exec oxfmt --check` on all changed files, and `git diff --check` —
passed.

Native HTML options use the browser's effective value semantics
(authored value or text); their runtime has no numeric index default.
Radix items continue using their existing runtime index fallback. All
three consumers migrated; no hook mechanism remains.

Oleg Isonen 2570bcdd69 fix: preserve cloned bindings and Content template design (#6533)
Cloning a Collection can leave its item bindings attached to the
original Collection. Content-mode template insertion also drops fixed
image attributes, rich-text editing can remove inline images, and
YouTube previews retain the previous thumbnail after a URL edit.

Reuse the Builder fragment-copy path for cloning, preserve exact fixed
props from the same Content Block template, protect mixed image/text
content from destructive editing, and refresh video previews. Direct
component metadata lookup now includes hidden required parts without
adding them to component lists.

Unsupported Resource fields now return validation errors instead of
unchanged success. Destructive confirmation failures retain their reason
through the existing issue-report pipeline, and reports include the
negotiated server API contract alongside the CLI contract. Contract
versions still use the existing serialized-schema hash algorithm.

## Verification

- [x] Reproduce each behavior fix and demonstrate regression tests fail
before/pass after.
- [x] Verify native Content template insertion, content editing, and
reload through isolated local Builder E2E.
- [x] Check copy permissions: reject arbitrary design values,
reused/mismatched prop keys, changed clone structure, and copies from
another Content Block.
- [x] Remove the unused clone implementation and reuse the UI's
copy/remapping logic.
- [x] Review documentation impact; existing instructions remain
accurate, no documentation update needed.
- [x] Regenerate fixture builds from committed snapshots; generated
fixture files remain unchanged.
- [x] Complete generated API/docs checks, 2,492 project-build tests, 88
protocol tests, 99 focused CLI tests, package typechecks, lint, and
formatting.
- [x] Full Luna/low evaluation suite: 6/6 fixtures pass after preparing
the Content runtime build. Existing baselines are incompatible with this
model override; they were not updated.
- [x] Independent Astra review: fixed and re-tested Global Root cloning
and protected-prop overwrite findings; final review has no findings.
- [x] Required CI passes: all 19 main-workflow jobs, visual regression,
submodules, and PR lint.

Ilya DevderandOleg Isonen a49a6769bd fix: refresh webhook form timestamp (#6530)
## Description

Closes #6437.

Each Webhook Form submission appended another hidden bot timestamp
input. The server reads the first value, so retries more than five
minutes after the initial submission used an expired timestamp.

Reuse the existing input and refresh its value on each submission
in both the React Router and Remix components.

## Steps for reproduction

1. Submit a Webhook Form.
2. Wait more than five minutes without reloading the page.
3. Submit the form again.

Before: the server reads the original timestamp and rejects the retry.
After: the submission contains one bot field with the current timestamp.

## Testing

- A browser regression test submits the same Form twice more than five
  minutes apart and verifies one current bot timestamp per request.
- Type checks passed for both router packages.
- Changed-file lint, formatting, and whitespace checks passed.

## Code Review

- [ ] Conceptual review
- [ ] Detailed review
- [ ] Test on preview

## Before requesting a review

- [x] Made a self-review
- [x] Added a test comment explaining why the first value matters

## Before merging

- [ ] Tested on preview environment
- [ ] Updated the manual test-cases document, if required
- [x] Added tests
- [x] No new environment variables

ff4a081f80 fix: export text pages in static builds (#6513)
Fixes #6440

## Description

Static exports currently omit Text pages such as `/robots.txt`,
`/ads.txt`, and `/.well-known/security.txt`. This generates their
routes, evaluates content through the existing page-data loader, and
uses Vike's native `pageContext.content` to write the exact text at the
configured file path.

Internal route directories are separate from public URLs so dot-prefixed
paths work. No generated writer script, text-page manifest, HTML
wrapper, or post-build file rewrite is needed.

## Dependencies

- Pin Vike to `0.4.267-commit-feffb0f`: native non-HTML output is
published in this commit prerelease but is not yet in stable `0.4.267`.
- Use Vite `7.1.12` and the compatible React plugin for SSG. Build
through `vike build && vike prerender` so Vike uses its matching Vite
dependency.
- Update React Router's `vite-node` dependency to `3.2.4` for
compatibility with the CLI's Vite 7 test environment.

## Validation

- All 1,173 CLI tests pass locally across 72 files, including all 79
prebuild tests for normal HTML, dynamic SSG routes, and React Router
builds.
- Text export coverage checks exact output for `/robots.txt`,
resource-backed `/.well-known/security.txt`, empty text, Unicode, and
HTML-like content.
- CLI and SSG fixture type checks, lint, and formatting pass locally.
- SSG fixtures regenerated; the packaged SSG test passes locally.
- All executed GitHub CI checks pass at
`201fa971616bb607ca35ee24a970f107eddee754`, including all six browser
shards. Shard 4 passed on retry after an MDX template rename timeout.
Visual regression is skipped and preview deployment remains gated.
- Corrected the existing animation navigation test for fork CI: wait for
the rendered component with the public fallback and retain the animation
initialization assertion when the private module is present.

## Manual verification

1. Export a static project with Text pages at `/robots.txt` and
`/.well-known/security.txt`.
2. Run the generated project's build.
3. Confirm both files under `dist/client` contain exactly the configured
text, including resource expressions.
4. Confirm normal pages still render HTML.

- [ ] Original author tested the updated export and confirmed it works.
- [ ] Preview tested (deployment approval remains gated).

Oleg Isonen 3c7dac7eb0 fix: resolve MCP preview and content graph reports (#6511)
## Summary

- Raise the document-reference graph budget independently of the 20-file
content hydration limit, and document the 2,000-document graph cap. This
lets the reported 29-post referenced query complete.
- Make iterative preview startup verify the generated project identity
endpoint instead of compiling the application route; exact route
validation remains with screenshot/capture.
- Keep production preview readiness tied to the application route even
when no CSS assets are present.
- Include a stable structured diagnostic when the browser DevTools
connection closes, while preserving the existing reconnect behavior.
- Document and test a safe leaves-first `convert-instance` migration for
required-part composite trees.

Closes #6508, #6515
Ref #6509, #6510

## Verification

- Content Engine suite: 656 tests passed.
- Vision suite: 85 tests passed.
- CLI preview/readiness/controller tests: 32 passed; project-build
instance conversion tests: 89 passed.
- CLI typecheck, targeted lint, formatting, and diff checks passed.
- The full CLI suite timed out in unrelated launcher/fixture tests under
parallel load. The preview-script and launcher tests passed with fewer
workers, and the MDX fixture test passed alone in 29 seconds. No full
local agent evaluation command was run.
- All required GitHub checks passed on latest commit `7f7b981` (29
successful; visual regression skipped).

## Remaining scope

- #6509 remains open: this PR improves diagnostics but does not
establish a stable Edge DevTools capture.
- #6510 remains open: this PR removes the initial route-compilation
dependency, but does not yet provide route-specific preparing/retry
status.

## Checklist

- [x] Review the change and preserve production preview route checks.
- [x] Add regression coverage for the review fix and required-part
conversion recipe.
- [x] Update MCP manual docs with the supported conversion order.
- [x] Run focused tests, typecheck, lint, and formatting.
- [ ] Run the full local agent evaluation suite (not run).
- [x] Confirm required CI checks pass on the latest commit.

Oleg Isonen c7bb11310d fix: Reload edited Video Content Block templates (#6512)
## Problem
Changing the preview image in a Video Content Block expands its default
parts into raw HTML in the saved MDX. On reload, nested `<div>` elements
were independently matched against unrelated div templates, producing
`ambiguous-template` warnings and unreliable saves. The edit should
reload as the same Video parts.

## Change
- Keep the existing MDX serializer and template overlay. When raw HTML
appears inside a resolved named template, let that parent overlay own it
instead of resolving each HTML tag as a separate Content Block template.
- Named templates nested inside it still resolve normally; raw HTML
outside it still reports genuine ambiguity.
- This avoids the larger component-specific serialization format and its
matching logic. The MDX source can still contain raw
`<img>`/`<div>`/`<button>` after the edit, but reload reconstructs the
original Video components and preserves the changed image.

For example, after editing `<Video />`, its saved `<Video><img
src="/replacement.png" />…</Video>` resolves the `img` as Video's
existing `VimeoPreviewImage`, not as an unrelated Image template. The
same rule keeps its nested `div` parts from colliding with HtmlEmbed.

## Checklist
- [x] Reproduce the preview-image save/reload failure using the real
YouTube template.
- [x] Add regression tests for reload, component identity, repeated
saves, and ambiguity outside the template.
- [x] Review the Content Block documentation; behavior and authoring
guidance are unchanged, so no docs change is needed.
- [x] Run project-build tests, typecheck, lint, formatting, and diff
checks.
- [ ] Run the full local agent evaluation suite (requires separate
approval; not run).
- [x] Confirm required CI checks pass on the latest commit.

## Verification
- Project-build tests: 2,491 passed across 91 files.
- Project-build typecheck, oxlint, oxfmt, and `git diff --check` passed.
- Focused regression rerun passed after asserting all Video parts
survive reload.
- Generated fixtures were not changed; fixture pipeline was not run
locally.

The separate report about adding new children inside a custom template
was not reproduced and is outside this PR.

Oleg Isonen 7ae2a8141e fix(cli): preflight MCP edits and preserve screenshot diagnostics (#6505)
## Summary

- Reject MCP build edits before local mutation when the negotiated
CLI/API editing contracts differ, with a direct instruction to restart
the MCP server using the current CLI. Reads, dry-runs, and legacy
servers remain unaffected.
- Preserve the browser capture's phase-specific timeout instead of
racing it with the generic MCP watchdog.
- Return stable structured diagnostics when a preview serves stale build
assets or the wrong generated project version.

## Triage

- Fixes #6479. The report records an MCP CLI contract different from the
API and says the current CLI succeeds. MCP now checks the contract
before attempting edit work and directs the agent to update/restart the
stale CLI.
- Addresses #6504. I could not reproduce the Windows timeout from this
macOS environment. The report's preview was stale and had no rendered
version; this change makes stale-project readiness and browser-phase
failures report distinct stable codes/issues. It does not claim to fix
an underlying Windows-only hang if the preview or browser process itself
never completes.

## Verification

- Full CLI suite: 72 files, 1,170 tests passed.
- CLI typecheck and Oxlint on changed files passed.

Oleg Isonen 05ea26f6a6 fix: block publish when JSON prop value is missing (#6507)
## What failed
A JSON prop can be saved without a `value`. The publish runner then
rejects the build, but the Builder was starting the publish request
before its best-effort diagnostics completed, so the user could miss the
cause in the Builder.

## Fix
- Add a pre-publish audit finding for JSON props without a value, linked
to the affected element.
- Block cloud and static publish requests when local publish audit
errors are present, so the Builder shows the diagnostic before any build
starts.
- Keep the CLI diagnostic as a fallback for builds published through
older clients or direct API flows.

## Verification
- Project-build pre-publish audit tests pass (11 tests).
- Project-build and Builder typechecks pass.
- Oxlint passes for the changed files.
2026-10-06 01:48:33 +02:00
Oleg Isonen 7767d281f3 fix: report missing JSON prop values during publish (#6506)
## What failed
The publish sync for build `41424aaa-6fdd-41b6-98cb-f444ba429654` fails
because `build.props[95]` is a JSON prop with no `value` field. The
failure was reproduced with the Webstudio CLI.

## Fix
The editor already stores `null` when a JSON binding is reset. For
previously saved malformed builds, the CLI now detects JSON props with
no value and reports the component label and prop name before schema
parsing fails. The user can correct the saved prop in the editor and
publish again; the CLI no longer silently rewrites the data.

## Verification
- HTTP client regression test verifies the malformed prop is identified
with its instance label and component.
- CLI sync test verifies the user-facing publish diagnostic.
- HTTP client and CLI typechecks pass.
- HTTP client tests pass (45 tests); CLI sync tests pass (17 tests).
- Oxlint passes for the changed files.

Oleg Isonen 6350169f12 fix(cli): persist MCP failure diagnostics for issue reports (#6502)
## Summary

- Persist only sanitized MCP failure diagnostics in the project-scoped,
ignored `.webstudio` state so the next CLI process can include them in
`report-issue`.
- Expire diagnostics after the existing 10-minute window and clear them
after a successful issue report.
- Record failures from `mcp run`, batch runs, and `single-op-call`;
await MCP server callbacks so diagnostics are saved before the response
returns.
- Add coverage for cross-process restore, project entity IDs, content
privacy, and clearing.

## Triage

Latest reporter issues reviewed: #6498, #6499, #6500, and #6501. I could
not reproduce the Linux/Windows-specific failures from this macOS
environment, and did not replay mutations against production projects.
This change targets the demonstrated reporting gap: one-shot CLI
failures are not available to a later issue-report process.

## Verification

- `pnpm --filter webstudio test` (72 files, 1,166 tests)
- `pnpm --filter @webstudio-is/project-build test` (91 files, 2,487
tests)
- CLI and project-build typechecks
- Oxlint on changed files

Oleg Isonen 3e310ddae3 fix: prevent canvas page switch reconciliation errors (#6494)
## Summary
- Keep the Canvas iframe mounted on page switches to avoid the blank,
slow document reload.
- Key the page's React boundary and place authored content under a
removable `display: contents` host node inside Canvas `<body>`. This
gives page teardown a generic DOM boundary.
- Use the merged sdk-components-animation fix from PR #36. The prior
animation implementation removed React-owned text nodes and triggered
`removeChild` when Canvas switched to an animated page.
- Add an end-to-end regression using the actual animation components and
retaining iframe identity. Keep the DOM-removal and preview navigation
regressions.

## Validation
- The animation regression reproduced the exact `removeChild` error
before the animation fix and passed with the fix.
- All checks passed on `f921c3011d`, including the submodule-ordering
check, all six Builder E2E shards, Builder builds, app/package checks,
typecheck, lint, and visual regression.
- Live switching speed on the affected project still needs a manual
check after deployment.

Oleg Isonen 00fcb26afe fix: align path rules with published routes and document headers (#6488)
## Problem

Builder page navigation, Authentication, and HTTP response headers used
different path matchers from published Remix pages. For example, Builder
did not select a `/docs/*` page at `/docs`, and a request for `/%64ocs`
could reach the `/docs` page without matching its Authentication rule.

## Change

- Use Remix's framework-independent router for page selection and
project path rules. Adapt Webstudio named splats and preserve encoded
static path segments.
- Keep Authentication's first matching rule and Headers' ordered
application of every matching rule.
- Preserve previously saved encoded literals such as `/%2A`, `/%3F`, and
`/%3Aid`. They match only their literal encoded pathname and cannot
become wildcards or parameters. Previously accepted malformed encoding
remains a literal path.
- Replace Builder's separate route ranking and URLPattern matcher.
URLPattern remains for page path validation and path editing.
- Use the request URL for the project-domain authentication exemption
instead of trusting `x-forwarded-host`. Generated HTML, XML, and text
routes share one authentication helper.
- Extend the HTTP headers guide and shared path pattern reference with
matching behavior, an iframe example, and verification steps.

## Validation

- Authentication package: 88 tests. New regression cases cover saved
Authentication and Headers rules, literal matching, route ranking,
parameter values, and a marker collision attempt. The regressions failed
before the fix and pass now.
- Project build: 2,484 tests, including 214 route and redirect checks.
SDK: 636 tests. CLI: 1,165 tests. Builder system: 5 tests.
- Typechecks: Authentication, project build, Builder, SDK, and CLI.
Lint, package boundaries, formatting, and diff checks pass.
- The fixture pipeline completed and made no additional changes. The
generated fixture files already changed by this PR remain included.
- Staging project build 196 published successfully using the companion
published-site Worker branch. The edge dispatcher was deployed from its
staging branch to normalize forwarded hosts. Live HTTP checks covered
base and child routes, dynamic pages, redirects, 404s, global headers,
and route-scoped headers. The generated site challenged protected base
and child paths, accepted the route password, and left public routes
accessible. The project domain intentionally skips route-specific auth
and has a separate staging Basic Auth gate, so the successful
route-password request was checked in the generated production runtime.
A forged `x-forwarded-host` no longer changes the hosted project-domain
auth decision.
- An initial CLI run alongside two other full suites timed out in one
fixture API test; that test passed alone, and the full CLI suite passed
when rerun alone.

## Compatibility

- [x] Preserve previously accepted percent-encoded route literals before
merging.
- The old URLPattern test asserting that `/docs/*` does not match
`/docs` was intentionally changed because the published Remix router
does match the base path. Tests for the removed custom route sorter were
replaced with router-selection tests.

## Rollout

- [x] Migrate matching in this repository.
- [x] Update user documentation.
- [x] Verify package consumers and related code.
- [ ] Merge

before releasing this PR. The current published-site Worker template
imports the removed `matchesPathnamePattern` export; without the
companion change, a published site fails at Wrangler build.
- [ ] After publishing the new `@webstudio-is/wsauth` version, update
the published-site Worker template’s pinned `0.301.0` dependency, remove
the temporary fallback, and deploy the hosted Worker.

Replaces #6482 so the review tracks the deployed `headers.staging`
branch.

Oleg Isonen c4684c141c fix: persist a valid JSON fallback when removing bindings (#6492)
## What changed

Resetting a JSON binding stores the expression's evaluated value. If it
evaluates to `undefined`, the serialized prop loses its `value` field
and fails the build schema. This change saves `null` instead for a
nullish fallback.

## Reproduction

Using the SDK `prop` schema locally, a JSON prop with the `value` field
omitted fails validation; adding `value: null` passes.

The full test suite was not run.

Oleg Isonen 8e4c080d95 fix: publish projects with legacy settings (#6480)
Publishing a legacy project can fail immediately with `Invalid input:
expected object, received null`. The editor reads settings from the
legacy `pages` field when `projectSettings` is SQL NULL, but the publish
snapshot check did not apply that fallback.

Read legacy settings from the saved production snapshot when needed,
preserving the custom-header plan check and its protection against
concurrent edits. No database migration or diagnostic logging is
included.

Verified through a read-only production database inspection and an
isolated reproduction using the affected build row: the previous code
throws the exact reported error before calling the publisher; the fix
reaches the isolated publisher. No production publishing was performed.

- [x] Reproduce the production failure using the original stored row.
- [x] Add regression tests for legacy settings and custom-header plan
enforcement; verify both fail before the fix and pass afterward.
- [x] Pass 40 build tests, 24 domain tests, project-build typecheck,
lint, and formatting checks.
- [x] Review documentation impact: existing publishing and header
behavior is unchanged; no documentation update is needed.
- [x] Verify all 42 CI checks, including six Builder end-to-end groups,
Linux/Windows fixture checks, and staging deployment.

Staging: https://pub.staging.webstudio.is

Production data repair, if approved, is separate from this code change.

Oleg Isonen 3d0f19ffe0 fix: complete and speed up publish validation (#6478)
## Summary

Complete Validate for large projects with linked MDX content, using the
same validation API in the dialog and MCP. Publishing continues
independently of diagnostics.

- Load MDX sources omitted from the embedded artifact and report storage
failures with typed diagnostic reasons.
- Reuse parsed MDX and template scope indexes; cache source reads in the
shared asset loader.
- Exclude conservative non-MDX query candidates while retaining explicit
invalid references for diagnostics.
- Give validation requests a 60-second server execution budget.
- Support both server bundles in E2E tests and make OAuth logging
initialization repeatable.
- Raise the project bundle import limit from 20 to 32 MiB to reproduce
the customer project.

## TODO / acceptance checklist

- [x] Import and inspect the customer project locally and on staging.
- [x] Reproduce missing embedded MDX sources and slow template
materialization.
- [x] Load omitted MDX sources and discover nested template
dependencies.
- [x] Report source-read failures using typed reasons rather than
matching error messages.
- [x] Reuse template scope indexes and remove duplicate source caching.
- [x] Route dialog Validate through the same API as MCP, after flushing
editor content.
- [x] Preserve publishing in parallel with diagnostics, including failed
or unfinished checks.
- [x] Fix JSON collection files being treated as MDX query candidates.
- [x] Preserve explicit invalid file references so they still produce
diagnostics.
- [x] Fix E2E routing across both generated server bundles and repeated
OAuth logging initialization.
- [x] Demonstrate the new review regressions fail before the fixes and
pass after them.
- [x] Run targeted tests, relevant typechecks, lint, formatting, package
boundaries, and generated API checks.
- [x] Run the full fixture pipeline and production builder build; no
generated fixture changes.
- [x] Build the exact staging project locally after the final review
changes.
- [x] Validate the exact staging project through MCP/CLI after the final
deployment.
- [x] Complete an actual staging publish after the final deployment.
- [x] Address PR comments: simplify the stream mock, explain every
diagnostic reason, and retain the existing diagnostic code contract.
- [x] Review documentation impact; these fixes restore expected behavior
and require no user instruction changes.
- [x] Finish CI on the final commit, including all six Builder E2E
shards.

## Verification

Local checks passed: 179 project-build tests, 78 CLI prebuild tests, 8
asset publication tests, 42 server tests, and 9 publish UI/helper tests.
The imported staging project also builds successfully.

The new explicit-reference regression and repeated-initialization
regression both failed before their fixes and passed afterward. A
production build serves the login route and dispatches tRPC requests to
its separate server bundle. Validation on staging project
`b9d23e54-5dbf-45c4-b6d8-bc4cf842a468` completed in 25.3 seconds after
deployment and 23.5 seconds after publishing: 92 documents included, 0
omitted, and 0 MDX errors. The [original staging publish job
rerun](https://github.com/webstudio-is/webstudio-saas/actions/runs/36647770120/job/109819143695)
succeeded end to end with the final artifact, including CLI/Remix
builds, worker deployment, and database updates. [CI on commit
`01a9d772dc`](https://github.com/webstudio-is/webstudio/actions/runs/36696154831)
is green, including all six Builder E2E shards and Windows/Ubuntu
fixture checks.

The comment follow-ups simplify the publication test mock and document
all diagnostic reasons. Production behavior is unchanged. The 8
publication tests, 6 schema tests, package typecheck, formatter, and
lint pass. Disabling the source cache makes the simplified regression
fail as expected. Final staging validation passed in 27.1 seconds with
92 documents and no omissions or MDX errors. One additional publish
attempt hit a database statement timeout during project sync, before the
build. A [retry with no code changes succeeded end to
end](https://github.com/webstudio-is/webstudio-saas/actions/runs/36647770120/job/109826767589).
CI is green on `01a9d772dc`.

Oleg Isonen e700a24210 fix: run publish checks in background (#6476)
## Summary
- Start dynamic and static publish diagnostics in the background,
without waiting for them before sending the publish request.
- Error findings, failed or hanging checks, and failures while reporting
them cannot block or delay publishing.
- Keep the standalone Validate action's reporting behavior unchanged.
- If diagnostics fail, the dialog explains that the publish request was
sent without waiting for them.
- The publish operation remains authoritative for authorization and
publish-job failures.

## Verification
- `pnpm --filter @webstudio-is/builder test --
app/builder/features/publish/publish-preflight.test.ts
app/builder/features/publish/publish-error.test.ts` (8 tests passed)
- `pnpm --filter @webstudio-is/builder typecheck`

Oleg Isonen a6a9049399 fix: validate published MDX before publish (#6468)
## Related issue

Related to #3550.

## Summary
- Run the existing published-MDX materializer during pre-publish
validation and surface its error diagnostics before starting dynamic or
static publishing.
- Reuse the dependency walk that builds the publication artifact to
limit validation to reachable Content Blocks, including blocks whose
asset is missing.
- Add actionable fix hints for unavailable MDX assets and invalid HTML
nesting.
- Show a compact error/warning count in the publish dialog, with a
details dialog that has counted Errors and Warnings tabs and hides empty
tabs.
- Include relevant IDs and navigation links in reports when available,
with guidance when they are not; allow users to copy all reports and
select the text.
- Resolve missing-document IDs against loaded asset metadata and show
the filename and Content Assets folder path when available.

The page-tree pre-publish audit already checks HTML content models, but
it cannot see content generated from MDX assets. This extends preflight
to that content using the same materializer and diagnostics as the
publish build. It also catches unavailable MDX assets before the publish
job starts.

## Plan and status

### Implemented
- [x] Reuse existing publish-time MDX discovery and materialization so
preflight checks the content that will be published.
- [x] Collect every page-tree audit error and warning, not only the
first finding for each severity.
- [x] Collect every MDX publish error and provide a location and
remediation hint.
- [x] Collect missing or ambiguous template warnings and
content-database omission warnings.
- [x] Show a compact error/warning total in the publish dialog.
- [x] Add a details dialog with standard panel padding, spaced and
separated findings, and counted Errors and Warnings tabs; hide empty
tabs.
- [x] Copy all reports from the dialog header and allow report text
selection.
- [x] Include diagnostic codes and relevant instance, asset, document,
and resource IDs in reports.
- [x] Keep “See issues” visible in the narrow publish panel.
- [x] Keep element navigation available from page-tree audit findings
and link content findings when the target is available.
- [x] Use the same findings UI for dynamic and static publishing.
- [x] Block publishing on errors and allow warnings to proceed.
- [x] Keep unexpected preflight failures visible to the user.
- [x] Show a preflight failure either in the open publish dialog or in a
toast when the dialog is closed, avoiding duplicate reports.
- [x] Replace opaque “Document … could not be loaded” errors with
actionable guidance, including the asset filename and folder path when
available.

- [x] Load linked document sources during MDX validation and prebuild
when they are absent from the compact content artifact.

### Regression checks completed
- [x] No-findings validation preserves the normal publish path.
- [x] Single and multiple findings show accurate totals and details.
- [x] The “See issues” action is visible in the publish panel and opens
diagnostics.
- [x] “Show element” navigation remains wired to the affected element
and closes the publish dialog.
- [x] More than five MDX errors and more than ten missing-template
warnings remain available in diagnostics.
- [x] Mixed MDX errors, audit errors, template warnings, and database
warnings are combined and counted.
- [x] Errors stop dynamic and static publishing; warnings do not block
publishing.
- [x] Error-only, warning-only, and mixed states show the right tabs and
counts, with empty tabs hidden.
- [x] Copy-all includes every error and warning with context, and report
text is selectable.
- [x] An open dialog receives inline preflight failures without a toast;
a closed dialog receives a toast without a duplicate inline report.
- [x] Missing-document errors include filename/folder context when
available and useful fallback guidance when metadata is unavailable.

- [x] Reproduce the linked-author failure with the affected project’s
hosted build, then confirm it builds successfully with the fix.

Oleg Isonen c0ddc4dca0 fix: Compile dynamic MDX from mutable variables (#6472)
## Summary

A Content Block MDX source can come from a mutable project variable, so
publication cannot safely narrow it to a single asset at compile time.
Include all MDX assets in the published project as candidates and thread
them through sync, dependency closure, and prebuild. Projects without
Content Blocks continue to skip article-body indexing and downloads.

Regression coverage exercises both the sync metadata and generated
prebuild output.

Follow-up to #6455.

## Checks

- [x] Project-build tests and typecheck
- [x] CLI sync tests and typecheck
- [x] Luna/low evaluation suite (all six fixtures passed; baseline
comparison unavailable for this model override)
- [x] Documentation impact reviewed

Oleg Isonen 6044792b77 docs: Explain Radix force-mount animation requirements (#6471)
## Summary

Document the animation constraints around Radix `forceMount`: closed
content remains mounted and needs explicit closed-state CSS, while Radix
suppresses CSS transitions and animations during height measurement, so
the first opening may not animate.

Updated Accordion and Collapsible docs, custom prop descriptions, and
generated prop metadata so the guidance appears in component discovery.

Closes #6197.

## Checks

- [x] Accordion and Collapsible documentation updated
- [x] Generated prop metadata refreshed
- [x] Package typecheck
- [x] Targeted Collapsible tests

Oleg Isonen adf1fd3aaf fix: show publish status only for selected domain (#6473)
## Summary
- Show the project-domain publish status only when the latest build
targets that domain.
- Keep the staging checkbox default tied to a staging publish.

A pending publish to a custom domain no longer makes the staging domain
appear to be publishing.

## Verification
- `pnpm -r typecheck` passed locally.

Oleg Isonen 432ca1172d fix: retain resources on XML pages (#6466)
## Summary

- Start resource discovery from the rendered XML root because prebuild
removes the page body wrapper before generating the route.
- Add a regression test for a Sitemap resource used by a Collection on
an XML page.

## Verification

- The regression test failed before the fix: the generated request graph
omitted `sitemap-resource` from `rootIds`.
- `pnpm --filter webstudio test -- src/prebuild.test.ts` — 78 tests
passed.
- `pnpm --filter webstudio typecheck` — passed.
- Formatting, lint, and `git diff --check` passed.
- Rebuilt the imported Spazio Flow project locally. `/sitemap.xml` now
returns all 12 eligible URLs; before the fix it returned an empty
`<urlset>`.
- Documentation impact reviewed: no user workflow or documented behavior
changed, so no docs update is needed.
- Fixture impact reviewed: no fixture inputs or generated contracts
changed, so no fixture regeneration is needed.

Oleg Isonen 8a46350c9a fix: Compile MDX Content Blocks in hosted builds (#6455)
Hosted MDX pages can publish successfully and then fail to render
because the publish runner skips their source files. Restore source
downloads and compilation for MDX Content Blocks, including dynamic
article queries and template dependencies.

Reuse the existing publication planner and local content compiler.
Markdown-only pages keep their bodies on demand; hosted MDX pages
download article sources and pay the necessary compilation cost in the
runner, not the publish API. Reject missing content databases and MDX
materialization errors instead of deploying an incomplete page.

Ref #6450
Ref #6454

## Checklist

- [x] Reproduce missing MDX content using the affected deployed build.
- [x] Restore hosted MDX compilation without duplicating the
static-export compiler.
- [x] Add a sync → compile → generated query → React server-render
regression with a metadata-only API bundle and a frontmatter-bound
Content Block.
- [x] Verify new regression checks fail without the required behavior
and pass with it.
- [x] Reject missing MDX sources and content databases; preserve remote
article bodies when no MDX Content Blocks need compilation.
- [x] Review documentation impact and update the Content Engine
publishing explanation.
- [x] Run CLI tests, typecheck, lint, formatting, and package-boundary
checks.
- [x] Run the full fixture link/sync/build pipeline; no generated
changes.
- [x] Rebuild the affected project locally and exercise its generated
production request handler: HTTP 200 with the article title and body.
Asset requests were served from synced local files.

The live project was not modified or republished. Its existing
title/description bindings still use an array access for a single-result
query; that separate project-data issue is not changed here. Agent
evaluations were not run. Affected sites need republishing after the
updated CLI artifact is deployed.

Oleg Isonen 11c31bdc25 feat: Warn MCP agents when a newer CLI is available (#6462)
## What changes

When MCP starts, the CLI checks npm's `latest` release while the project
session and API contract are loading. If a newer CLI is available, the
MCP initialization instructions tell the connected agent which versions
are running and recommend restarting with the latest CLI. The CLI never
updates or restarts itself.

The registry request has a 1.5-second timeout and fails open on network
or response errors. It may add up to 1.5 seconds to startup if the
project session finishes before the check; the existing server
compatibility check remains the authority for whether writes are
supported.

## Verification

- [x] Added tests for newer, same/older, invalid, and unavailable
registry responses; the newer-version test failed when the check was
temporarily disabled.
- [x] Verified the update notice reaches the connected MCP client; the
handshake test failed when the notice was temporarily omitted.
- [x] Full CLI suite: 1,159 tests passed.
- [x] CLI and project-build typechecks passed; focused MCP
initialization integration test passed.
- [x] Lint, formatting, and diff checks passed.
- [x] Documentation impact reviewed: no docs change is needed because
the notice is sent dynamically at MCP startup.
- [ ] Full Luna/low agent evaluation suite: approval requested, not
received; not run.

Oleg Isonen e1e5bc152e feat: append response header rules for last-match precedence (#6460)
Response headers now use list order when more than one rule sets the
same name on a path: the last matching rule wins. New or edited rules
currently move to the top of the Builder list, which would make older
rules override them. Append those rules instead and explain the
precedence in the settings UI. Authentication list behavior is
unchanged.

Validation: SDK response-header tests and typecheck, CLI response-header
tests, SDK build and declaration build passed.

Oleg Isonen 7fd91301d6 fix: Retry responsive preview routes and report linked project IDs (#6458)
Responsive verification could reject an interior route while the
refreshed preview was still settling. Managed responsive captures now
use the same bounded retry as single screenshots. If the route keeps
returning HTTP 4xx/5xx, the tool reports the route failure instead of
calling it the wrong site.

Issue reports now use the resolved linked project ID, including when the
CLI was started without --project. This makes future project-specific
reports traceable without adding URLs or customer content.

The immediate false rejection is removed for transient failures. A batch
may be recaptured up to twice with a one-second wait between attempts.
Persistent route or server errors still fail and need investigation.

Ref #6456
Ref #6452
Ref #6457
Ref #6396

## Verification

- [x] New responsive retry and HTTP-classification tests failed before
the changes and pass afterward.
- [x] Full CLI suite: 1,153 tests passed. CLI typecheck, formatting and
targeted lint passed.
- [x] Focused sitemap, bundle-loading, and API-compatibility tests
passed.
- [x] Reviewed authoritative docs: no user workflow or documented input
changed, so no docs update is needed.
- [x] Fixture inputs and generated outputs are unaffected; no fixture
regeneration is needed.
- [ ] Full Luna/low agent evaluation suite: approval requested, not yet
received.
- [ ] Verify the affected interior route on a released CLI. The original
report lacks the project and route identity, so this PR does not claim
that specific site is fixed.

Oleg Isonen 9b1100f25b fix: Restore hosted Assets queries (#6454)
Hosted Assets queries started returning 502 in 0.301.0 because publish
sync omitted their query database. Restore that database for hosted
builds while keeping Markdown body-reference queries on demand. Static
exports still prepare their database in the build runner.

Reject builds with Assets queries but no database before changing
generated files, so this failure cannot silently produce another broken
deployment or erase the previous generated output. Uses the existing
shared query compiler; no MCP-specific logic or API schema changes.

Closes #6450
Ref #6427

Replaces #6453 with the same commits on `assets.staging`, which matches
the staging deployment branch policy.

## Checklist

- [x] Reproduce the reported 502 and verify the fix on project and
custom origins.
- [x] Preserve static export behavior and on-demand Markdown loading.
- [x] Add a regression test for rejecting missing databases; demonstrate
failure before the fix and success afterward.
- [x] Review documentation impact and update the Content Engine
publishing explanation.
- [x] Run relevant tests, Builder/CLI typechecks, lint, formatting, and
package-boundary checks.
- [x] Run the full fixture link, sync, and build pipeline against the
patched preview API. Regenerate all eight JSON snapshots with the
current formatter; parsed data is unchanged and generated application
files are unchanged.

Validation: 88 CLI tests, 22 Builder tests, and four no-body-read
publication tests pass. Fixture size checks were unavailable without
compiled app bundles. Agent evaluations were not run. Existing affected
sites need republishing after the fix is deployed.

Oleg Isonen d78e770d82 perf: Keep article indexing out of publish API requests (#6427)
Ref #6416

The publish workflow was doing too much work in one short-lived API
request. This moves content indexing into the build runner and keeps
article bodies out of hosted/SSR sync.

## What changed

- The build-bundle API can return the lightweight project bundle without
preparing a full content index.
- The CLI downloads required assets directly from storage and builds the
index locally for SSG. Asset downloads remain bounded to 10 concurrent
requests.
- Hosted/SSR sync skips Markdown and MDX article downloads and does not
compile an article index. It still downloads regular assets needed by
the build.
- Markdown body queries use stored frontmatter and fetch only the
requested article at runtime. MDX still needs source downloads and
compilation for SSG.
- Public MCP and content-engine docs explain the Markdown/MDX tradeoff.

This removes article parsing and article-body transfer from the tRPC
request. SSG still downloads article sources from storage and compiles
MDX in the build runner. Hosted runtime article reads remain on demand.

## Checklist

- [x] Keep the tRPC bundle request limited to project metadata and
necessary records.
- [x] Prepare SSG content indexes in the build runner; keep hosted
article bodies out of sync.
- [x] Cover no-body query preparation, direct asset reads, and
SSG-versus-hosted sync behavior with regression tests.
- [x] Update public CLI, MCP, and content-engine guidance.
- [x] Regenerate and verify fixtures.
- [x] Run workspace tests, typechecks, lint, formatting,
package-boundary, generated API/docs, and fixture-size checks.
- [ ] Verify the deployed publish flow has comfortable margin below the
hosted API timeout.

## Verification

- `pnpm -r --workspace-concurrency=1 test`: passed, including all 3,082
Builder tests and 1,150 CLI tests.
- `pnpm -r typecheck`, `pnpm lint`, `pnpm check:package-boundaries`,
`pnpm check:generated-api`, `pnpm check:generated-docs`, `pnpm
check:fixture-sizes`, and `pnpm exec oxfmt --check`: passed.
- The new hosted article-download regression test was confirmed to fail
with the old behavior and pass after the fix.
- A deployed end-to-end publish timing check is still needed, so this PR
remains draft.

Oleg Isonen df7ed327ab refactor: clarify pathname rule matchers (#6446)
Authentication and custom response headers use the same route-rule
syntax, but the shared matcher and validator had auth-specific names.
Give those functions generic names in `wsauth` and update the Builder
header UI and SDK response-header schema to call them directly. All
basic-auth logic remains in `wsauth`; this change adds no package or
re-export.

The project-build page matcher is different: it uses `URLPattern` and
returns decoded parameters. Rename it to `matchUrlPattern` and document
the behavior difference. For example, `/docs/*` matches `/docs` for
authentication and headers, but not for the page matcher. Tests cover
both behaviors.

This renames the two public `wsauth` route exports. Published workers
pinned to the older package retain the old API; the SaaS worker can
adopt the new names after this package is released.

Validation: `wsauth` tests, including its packaged consumer test; SDK
page and response-header tests; project-build route and redirect tests;
SDK, `wsauth`, project-build, and Builder typechecks.

## Summary

- Declare that screenshot requires exactly one target: `url` or `path`.
