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.

Related #6520 — [Multi-step Forms with resumable local
drafts](https://github.com/webstudio-is/webstudio/issues/6520)

The existing Webhook Form bug #6437 and prior legacy-form fix #6436 are
outside this new-Form feature and are not claimed as closed here. The
old email planning PR #6486 is superseded by this description.

- [x] **Use the canonical server token for Preview email:** The user
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
app/shared/nano-states/selection-reveal.test.ts
app/shared/nano-states/selection-reveal-render.browser.test.tsx
app/shared/nano-states/components.test.tsx
app/shared/nano-states/props.test.ts
app/shared/nano-states/instance-selection.test.ts
app/canvas/instance-selection-events.test.ts
app/canvas/selected-instance-effects.test.ts` — 7 files, 84 tests
passed; the final resolver rerun passed 14 tests after adding one
additional authored-expression regression (85 tests across the same
files).
- `pnpm --filter @webstudio-is/project-build exec vitest run
src/runtime/component-catalog.test.ts
src/runtime/component-templates.test.ts` — 16 tests passed.
- `pnpm --filter @webstudio-is/sdk-components-react-radix test` — 20
tests passed.
- `pnpm --filter @webstudio-is/builder exec tsc --noEmit` — passed.
- `pnpm --filter @webstudio-is/sdk --filter @webstudio-is/react-sdk
--filter @webstudio-is/sdk-components-react --filter
@webstudio-is/sdk-components-animation --filter
@webstudio-is/sdk-components-registry --filter
@webstudio-is/project-build typecheck` — all 6 packages passed.
- `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 e69a3d2f8e feat: Create structured MDX entries from collection folders (#6317)
## Paragraph editing follow-up — 42a16db02c (September 9)

Nested formatted paragraphs now retain their text, links, styling
identity, and existing labels during editing and saving. No database
migration.

- [x] Review all four changed text-editor files.
- [x] Preserve text before and after nested links inside emphasis,
strong text, and spans.
- [x] Preserve existing instance labels on save and keep inherited
formatting from overwriting a link's styling identifier.
- [x] Demonstrate regression failures without each fix, then pass all 41
focused text-editor and MDX synchronization tests.
- [x] Pass Builder typecheck, lint, formatting, and diff checks.
- [x] Verify the reported paragraph in Design and Content modes: edits
reach MDX and survive reload; original text restored. Verify matching
link color and underline inside and outside editing.
- [x] Review documentation and fixture impact: this restores existing
documented behavior; no fixture inputs, generated output, or
documentation changes are needed.
- [x] Commit and push the reviewed fixes.
- [ ] Confirm CI on this commit before merging.

Full E2E and agent evaluations were not rerun for this focused
follow-up. Earlier CI and suite results below apply to their recorded
commits, not this new head.

## Final verification — 50093ed2b7 (September 9)

Article edits now retain inline formatting and save newly inserted
custom components reliably. Saving a file no longer sends a second
project-sync write that could restore an older revision. No database
migration.

- [x] Fix iframe-blur saves, inherited template defaults, unused
resolved assets, and stale template tag metadata.
- [x] Remove duplicate server writes for already saved file revisions;
share the result with the canvas using the existing external-content
sync channel.
- [x] Demonstrate new regression tests fail without their fixes and pass
with them. Keep E2E file-write, content-order, and reload assertions;
remove the obsolete duplicate metadata-write wait.
- [x] Pass all 2,955 Builder tests, all 2,409 Project Build tests, and
all 8 focused MDX E2E checks.
- [x] Pass Builder and Project Build typechecks, lint, formatting, and
diff checks.
- [x] Run the complete fixture pipeline with no generated changes. The
later Builder-only save-acknowledgment changes affect no fixture inputs
or outputs.
- [x] Verify live article fields, hero replacement/save/reload/restore,
Accordion text edits, and YouTube URL edits. Verify UI edits reach MDX
and MDX edits persist after reload. Restore original article content.
- [x] Review documentation impact: these fixes restore the documented
Content Block editing behavior; no further documentation change is
needed.
- [x] Apply `visual-change-approved` after the user's explicit approval
of the 24 reviewed intended visual changes.
- [x] Commit and push the reviewed changes; worktree is clean.
- [x] Confirm CI and mergeability on this final commit: all 19 Main
workflow jobs passed, including all six E2E shards; PR lint and
submodule checks passed. Visual approval run 34383497017 passed. Its
predecessor reported the 24 intended differences; all 24 current images
were byte-identical to the reviewed report, with zero capture errors.
GitHub reports no merge conflict.

Agent evaluations were explicitly skipped for these final runtime fixes,
as requested. Earlier evaluation results below apply to their recorded
commits, not this final commit. This summary supersedes historical
pending-check notes below. The PR has not been merged.

---

## Final merge check — 9bc31ca679 (September 9)

- [x] Merge main without rewriting branch history. Preserve main's
image-picker fix and description-list validation.
- [x] Reset inherited HTML parent context at template boundaries. All
four new regressions fail without the fix and pass with it.
- [x] Fix shared navigation style composition and alignment; verify the
browser regression fails before and passes after. Review focused
screenshots.
- [x] Pass 2,408 Project Build tests, 251 design-system tests, and 3
image-picker tests; Builder, Project Build, and design-system
typechecks; lint, formatting, and diff checks.
- [x] Run the complete fixture pipeline with no generated changes.
- [x] Rerun all six agent evaluation scenarios on the merged code with
GPT-5.5. All functional checks pass; incompatible/missing token-baseline
comparison remains explicitly disabled.
- [x] Review documentation impact: this merge preserves documented
behavior; the image-editing guidance was already updated in f90e39cfcc.
- [x] Commit and push; worktree is clean and GitHub reports no merge
conflict.
- [x] Confirm Main CI on 9bc31ca679: all 19 jobs passed, including all
six E2E shards.
- [x] Review final visual artifact 10110845203 from run 34367911826: 24
added/changed stories, zero capture errors. Reviewed collection dialogs
and icons, light/dark login gradients, dashboard and project-settings
navigation, panel spacing, button variants, inset lists, and resettable
labels. Fourteen captures are byte-identical to the previously inspected
CI images. Updated navigation and collection-settings captures were
inspected; the formerly blank story renders normally. Pixel measurements
confirm the columns story retains its intended column positions (second
column x=261, third around x=388).
- [x] Apply visual approval after renewed explicit user approval.
Final-head CI is tracked above.

The live hero replacement and article/custom-component checks below are
now complete. The PR has not been merged.

## Merge-readiness follow-up — September 9

- [x] Remove contradictory image guidance and add an executable
writable-source/read-only-alt binding recipe. Regenerate CLI/MCP docs.
- [x] Verify the recipe regression fails with the old guidance and
passes with the new guidance. All 10 focused documentation tests, 2
content-reference tests, CLI/docs typechecks, lint, formatting, and
generated-documentation checks passed.
- [x] Rerun all six agent evaluation scenarios with GPT-5.5: all
functional checks passed. The incompatible/missing token-baseline gate
was explicitly disabled; existing baselines are unchanged.
- [x] Commit the documentation follow-up as f90e39cfcc.
- [x] Review existing CI screenshots and identify unintended shared-list
alignment changes. Implement a local shared-style composition/alignment
fix with a regression test demonstrated failing before and passing
after; all 251 design-system tests and its typecheck passed.
- [x] Visually verify and push the shared list fix in 9bc31ca679. The
focused run compared 28 stories; navigation is left aligned, column
layouts remain intact, and the previously blank collection-settings
story rendered normally. No product fix was inferred from that one blank
capture.
- [x] Review and approve the intended visual differences. See the
current final-head CI status above.
- [x] Verify these changes affect no fixture inputs or generated fixture
output. No database migration.

The previously pending live hero-swap and article/custom-component
checks are now complete. See the current verification summary above.

---

## Article editing follow-up — d307c8ba3d (September 9)

The target blog's hero source was incorrectly marked read-only. It now
uses the existing writable image picker. Reading time and the author URL
also use direct writable values. Time properties now have native
date/date-time controls. No database migration.

- [x] Fix the target's hero source, reading-time structure, and author
URL bindings while preserving the current content and link destination.
- [x] Verify Content-mode category, title, excerpt, date, reading-time,
shared image Description, author name/URL, MDX heading, and list-item
edits reach their source files. Check reloads and restore test values.
- [x] Add date-only, local timestamp, UTC timestamp, empty-value, and
legacy-value regression coverage; demonstrate failure without the date
control and passing results with it.
- [x] Fix the macOS Bash runner's empty-argument failure. Demonstrate
default invocation and argument-forwarding regressions fail without
their behavior and pass afterward.
- [x] Update authoritative Content Block/Time docs and generated CLI/MCP
guidance: inventory every article field, use direct writable bindings
and appropriate controls, check saved source and reload, and never infer
full editability from one heading.
- [x] Pass 291 date/text/Time/design-system tests (one existing skip), 2
runner tests, and 9 documentation tests; relevant typechecks, lint,
package boundaries, formatting, and diff checks.
- [x] Run the complete fixture pipeline: no generated fixture changes.
The later runner/docs-only edits do not affect fixture inputs or
outputs.
- [x] Run the full Builder E2E suite: 82 passed. This used an explicit
reporter; the default invocation correction was then covered by the
runner tests.
- [x] Run all six agent evaluation scenarios on gpt-5.5 after the final
image guidance correction. All functional checks passed. The older-model
token-baseline gate was disabled explicitly; accepted baselines were not
changed.
- [x] Review, commit, and push code and generated documentation.
- [x] With explicit approval, replace the live hero image through
Content mode, verify the MDX reference and reload, then restore and
verify the original image.
- [x] Complete the article-field checks listed above. Insert Accordion
and YouTube from templates; verify UI edits reach MDX and MDX edits
persist after reload. Restore the original article content.
- [x] Inspect CI for 7834d90a61: formatting, lint, typechecks, generated
docs, package/Builder tests, build checks, and five E2E shards passed.
The long MDX lifecycle exhausted its total 120-second budget at its
final assertion; the trace showed completed edits and reloads, not a
stalled save.
- [x] Give only that lifecycle a 180-second total budget; leave
individual save waits and assertions unchanged. Both local repeats
passed (plus setup). Push d307c8ba3d; this test-timeout-only follow-up
affects no fixture inputs or generated output.
- [x] Verify Main CI for d307c8ba3d: all 19 jobs passed, including all
six E2E shards. Visual approval remains separate.
- [x] Finish visual review and approval after correcting navigation
alignment and verifying the collection-settings story renders. The user
approved the reviewed 24 intended differences.
- [x] Recheck target publication preparation: seven documents included,
zero omitted, zero missing-template omissions. No deployment.
- Deferred: manual Storybook/screenshots; not authorized for this pass.

These results supersede the earlier pending image-product decisions and
live-check notes. Evaluation status for the latest fixes is recorded
above.

## Blog authoring fixes — 6359f979a3 (September 9)

This review fixes failed UI-to-MDX saves, missing source Undo/Redo,
editor recovery and focus, and publication preparation for the migrated
blog. No database migration.

- [x] Stop treating template-record ordering as a style edit; still
reject actual style changes that cannot be saved in MDX.
- [x] Share save-preparation errors with property controls across the
canvas frame.
- [x] Keep malformed MDX as an unsaved draft, with repair and discard
paths; focus the source editor when opened from the Navigator.
- [x] Enable supported Content-mode Move actions using the existing
central permission rules.
- [x] Keep source Undo/Redo separate from transient rendering history.
Serialize rapid commands, wait for pending canvas edits, reject
stale-source conflicts, and retain the last 20 edits per project
session.
- [x] Fix publication candidate discovery for projected documents and
unrelated author references; keep rejecting unsupported references used
as the actual MDX source.
- [x] Demonstrate regression tests failing without their fixes and
passing afterward.
- [x] Run the complete Builder (2,938), Content Engine (559), and
Project Build (2,395) suites: 5,892 tests passed.
- [x] Pass relevant package typechecks, root lint, formatting, package
boundaries, and diff checks.
- [x] Run the full fixture pipeline; no generated fixture changes.
- [x] Review documentation impact and document draft recovery and source
Undo/Redo.
- [x] Verify live heading edits, author-file edits, malformed-draft
recovery, and immediate delete/Undo/Redo; restore test content and
confirm persisted source.
- [x] Verify target publication preparation: seven documents included,
zero omitted, no missing-template omissions. This did not deploy the
site.
- [x] Review, commit, and push.

### Remaining verification and decisions

- [x] Correct the target's read-only Image source binding. The existing
Content-mode picker replaces the article reference; shared Description
edits use Asset settings. No new image-editing API or data model is
needed. See the latest verification limits above.
- [x] Repeat the full E2E and agent evaluation suites after these
changes: 82 E2E tests and all six evaluation scenarios passed.
- [x] Repeat the live Accordion/YouTube insertion and editing flow after
the save fixes, including UI-to-MDX saves and MDX edits surviving
reload.
- Historical note: this round did not run CI or Storybook checks; later
results are recorded above.

Unknown JSX already has source-range lint diagnostics; it remains an
editable missing-template placeholder, not an unconditionally blocked
save. The target author's binding was also repaired through the UI so
Content mode can edit its referenced author file. Shared resolved URLs
remain read-only text; the image picker changes the article reference,
and Asset settings edits the shared Description.

This section supersedes earlier claims of complete verification for the

## Sync and import verification — a2a567551c (September 9)

Ordinary `link` → `sync` → `import` now exports the current saved
Builder project with its current assets. It no longer mixes an older
published build with current files. Import uploads assets before
assigning their source folders, then restores those assignments when
importing the bundle.

- [x] Fix foldered asset imports without a database migration.
- [x] Preserve file formats, folder assignments, build metadata, and
stable repeat-sync output.
- [x] Keep explicit `--buildId` export behavior unchanged; default sync
does not require publishing.
- [x] Review implementation and demonstrate regression tests failing
before the fixes and passing afterward.
- [x] Update protocol test servers for the current Builder data
endpoint.
- [x] Review documentation impact and update CLI documentation and
README.
- [x] Run all 1,121 CLI tests and 43 HTTP-client tests, both package
typechecks, root lint, package boundaries, formatting, and diff checks.
- [x] Run the full fixture pipeline and include expected current-build
fixture changes.
- [x] Verify the real source through the local CLI: repeated sync gives
identical output; import into the supplied target succeeds. Blog listing
and article rendering were also checked during the import investigation.
- [x] Commit and push the fix.
- Deferred at user request: agent evaluations for this round. Later CI
results are recorded above.

Sync still downloads the project and missing asset files and builds the
content index locally. This is not a transfer-free operation. Default
sync exports editable-build metadata rather than published deployment
metadata; use the explicit build option when selecting a particular
build.

## Final review and verification — ab3a6b7c55 (September 9)

Existing entries now use the same field controls as New entry. The
author-name permission fix, field-level validation, publishing warnings,
and final cache fixes are included. No database migration.

### Completed

- [x] Review all 38 local files, including entry autosave, revision
conflicts, permissions, shared fields, collection discovery, and
publishing diagnostics.
- [x] Allow existing-folder setup without rewriting entries or rejecting
unconfigured frontmatter.
- [x] Add Entry settings with autosave, repairable invalid fields,
immutable filename slugs, and preserved MDX body/unknown properties.
- [x] Warn before publication when missing or ambiguous custom templates
omit content, including discovered dynamic sources.
- [x] Allow authorized frontmatter writes to referenced Markdown author
files and preserve error messages across the canvas-frame boundary.
- [x] Reject impossible integer limits, slugless generated-filename
patterns, and slug maximum length zero. Existing raw configurations
remain readable for repairs.
- [x] Share collection discovery across Assets, file editors, and
property controls. Builder first synchronizes project asset metadata
into the browser. The browser then groups that metadata once per update
and shares configuration/template reads, instead of repeating them for
each control. This does not remove initial synchronization or
entry-frontmatter reads. Preserve project/access isolation, refresh
retries, stale-response protection, and duplicate-filename invalidation.
- [x] Demonstrate new regressions fail before fixes and pass afterward.
- [x] Correct the folder-drag E2E's obsolete root-folder assumption and
verify remembered-folder persistence.
- [x] Review and update authoritative Content Engine and Content Block
documentation.
- [x] Merge current main and regenerate the conflicting CLI
documentation from its source.
- [x] Fix generated previews with shared development dependencies:
invoke React Router binaries through Node, isolate each preview's Vite
cache, and forward script options correctly through npm and pnpm.
- [x] Fix a false MDX conflict when a new edit arrives immediately after
the previous save is acknowledged. Advance the local revision before
asynchronous parsing and ignore stale refresh results.
- [x] Run the full fixture link/sync/build pipeline. Generated changes
contain only the expected React Router scripts and Vite cache location.
No database migration.
- [x] Review the final diff and scan added lines for credential
patterns.

### Verification results

- Builder: **2,934 tests passed**. CLI: **1,120 tests passed**.
- Content Engine: **559 passed**; Asset Uploader: **291 passed**;
Project Build: **2,394 passed**; Design system: **250 passed**.
- The clean full workspace run passed all 35 non-CLI packages. Its two
CLI failures exposed pnpm argument forwarding; the complete CLI rerun
passed after that fix. Earlier load-related test timeouts did not recur
in the clean run.
- All workspace typechecks passed. Builder and CLI typechecks and
repository lint were repeated after their final changes. Package
boundaries, generated API checks, and the complete
generated-documentation gate passed. Documentation was regenerated from
source; the post-commit clean-file check passed.
- Full Builder E2E: **82 passed** from a fresh build, including
generated previews, collection creation/reload, MDX editing, stale
revisions, and permission checks. The isolated disposable test database
was cleaned up afterward; development data was untouched.
- Full agent evaluations: **all six scenarios passed on gpt-5.5**,
including every functional check for Markdown blogs, reference
discovery, MDX article editing, authentication, fonts, and design input.
The account cannot use the old **gpt-5.4-mini** baseline model. Five
baseline comparisons are incompatible and the MDX scenario has no
accepted baseline; token-baseline gating was disabled explicitly.
Accepted baselines are unchanged.
- New preview and MDX regressions were demonstrated failing before their
fixes and passing afterward.
- Working-tree/diff checks passed. Main was merged without rewriting
branch history. CI was not checked, as requested.

### Final delivery checklist

- [x] Finish the full Builder E2E rerun.
- [x] Finish the full agent evaluation rerun with the authorized
accessible model.
- [x] Commit, verify the clean generated-documentation gate, and push.
GitHub reports the branch mergeable with current main.

No known code or functional-test blocker remains from this review. CI
was not checked at the user's request. Manual Storybook/screen-reader
checks remain deferred; the automated E2E and agent visual checks above
passed.

The historical review sections below retain their original run results.
This section supersedes earlier claims about strict entry validation,
entry editing, browsing reads, and evaluation authorization.

## Outcome

Content editors can create structured MDX entries from a collection
folder without writing frontmatter. Designers configure flat fields,
limits, optional slug behavior, and the Markdown template in the
Builder.

## High-level goals

- [x] Keep folders ordinary in the database and derive collection
behavior from a direct **collection.json**.
- [x] Add **Use as content collection** to folder creation.
- [x] Give designers a visual configurator for the JSON Schema and MDX
template.
- [x] Show a collection badge and a generic **New entry** action.
- [x] Generate independent MDX entries from the configured schema and
template.
- [x] Keep the current page unchanged after creating an entry; no
automatic preview navigation.
- [x] Select direct MDX entries with URLPattern filename rules; keep
ignored files as ordinary supporting assets.
- [x] Keep reserved collection files out of collection query results and
generated content indexes.
- [x] Preserve broken collections as visible, repairable collection
folders.
- [x] Restore normal folder behavior when **collection.json** is
removed.

## Implementation todos

- [x] Add the Content Engine collection contract, default
schema/template, slug normalization, validation, serialization, and
entry generation.
- [x] Discover collections from Assets files without a database folder
type or migration.
- [x] Create **template.mdx** and **collection.json** when the folder
checkbox is selected.
- [x] Add basic field controls for text, long text, slug, number,
integer, and Boolean values.
- [x] Support required fields, string length limits, numeric limits,
template defaults, and generated slugs.
- [x] Add designer collection settings and template editing.
- [x] Remove dynamic preview-page configuration and ignore its legacy
metadata.
- [x] Add the schema-generated **New entry** form and creation endpoint.
- [x] Preserve reserved-file portability in authenticated export/import
while excluding it from content query and generated-index results.
- [x] Document the feature in the authoritative Content Engine guide.

## Deep review checklist

A checked item means the area was inspected and evidence was recorded.
It does not mean the behavior passed. Unresolved defects and product
decisions remain listed in **Review findings**.

### 1. Product contract

- [x] Decide whether the collection checkbox creates defaults
immediately or opens the configurator first.
- [x] Decide whether existing folders can be converted through the UI.
- [x] Define collection activation when **collection.json** exists but
is invalid.
- [x] Define an entry: every valid direct MDX child or only files
created through **New entry**.
- [x] Confirm collection membership is direct-child only and nested
folders can define their own collections.
- [x] Define designer, content editor, viewer, service, CLI/MCP,
old-client, and direct-API authority.
- [x] Decide whether content mode is simplified UI or a server
authorization boundary.
- [x] Decide whether slugs are permanently immutable.

or whole-project publication.
- [x] Decide what happens to the preserved template after collection
removal.
- [x] Define the promised JSON Schema dialect and supported subset.
- [x] Decide whether temporary invalid collection states are admitted
for repair.

invalid content.
- [x] Review removing, removed, moved, renamed, restored, duplicated,

- [x] Preserve raw repair when the configurator cannot parse the schema.
- [x] Show collection health after repair.
- [x] Prevent custom-template leakage to content editors when config
cannot identify it.

### 24. Entry navigation

- [x] Remove dynamic preview configuration and automatic navigation
after entry creation.
- [x] Verify entry creation leaves the selected page unchanged, with or
without a slug field.

### 25. Accessibility and responsive behavior

internals.

### 28. Verification strategy

- [x] Unit-test schema, slug, merge, serialization, and validators.
- [x] Demonstrate each new regression test fails without its fix.
- [x] Run affected unit suites, typechecks, lint, docs checks, E2E,
fixture-impact review, and final diff review.
- [x] Review authoritative documentation impact.

## Persistence and recovery

No database migration is needed. Folders remain ordinary database rows;
their direct **collection.json** activates collection behavior. This PR
adds no table, column, index, RPC, folder type, or backfill.

- Setup writes the template first and **collection.json** last.
Interrupted setup leaves an ordinary folder and can be retried.
- Existing immutable File revisions, conditional Asset updates, and
upload reservations provide conflict detection and retry-safe entry
creation.
- Settings saves validate the intended template and schema together,
then write only the files that changed. Existing entry field errors stay
repairable and do not block unrelated saves, queries, or publication.
New entry creation remains strict.
- Invalid or interrupted collections remain visible and repairable.
Configuration/template structure errors remain distinct from entry-field
errors; entry-field errors do not invalidate the entire collection.
- Public/service publication excludes configuration and template files.
Authenticated CLI exports retain them for lossless import.

## Review findings

The implementation review is complete. Confirmed defects were fixed and
the following tradeoffs remain explicit.

### Fixed

- Enforced collection structure and permissions across REST, runtime
patches, import, query, and publication, while keeping existing
entry-field errors non-blocking for queries and publication.
- Preserved Undo/Redo, including restoring shared File revisions in
cloned projects.
- Rejected forged shared-file metadata while preserving metadata edits
on legacy files with null uploader provenance.
- Added retry and recovery behavior for setup, settings saves, lost
responses, and transient reads.
- Moved collection setup into one retry-safe server operation and kept
the local Builder update as one Undoable transaction.
- Centralized collection inspection and limited schemas to the flat
fields the configurator can represent. Opening a collection still reads
its entries in the background to report field errors.
- Guarded stale dialogs and deferred saves against permission changes,
protected files, project switches, and replaced revisions.
- Kept Asset settings open while choosing nested folders; the existing
browser regression fails before the fix and passes afterward.
- Preserved required Boolean false values, field-level errors,
dirty-close prompts, and inline Markdown editing.
- Separated authenticated portable exports from public runtime assets.
- Updated the authoritative Content Engine guide.

### Known tradeoffs

- A failure after template content saves but before configuration saves
can temporarily leave an invalid collection. Retrying the settings save
completes it; otherwise the visible files allow repair. The
template/config rename endpoint remains retry-safe and rolls back a
rename when its config write fails.
- Cloned-project Undo can retain an unused prior File revision. Separate
read-then-delete cleanup could race with another restore, so this path
retains the revision.
- Build/asset persistence and import already use multiple calls. This PR
validates before writes and provides retry/conflict handling; it does
not provide a transaction spanning every resource or a global collection
lock.
- Opening a collection loads its configuration and template through
shared Builder discovery, then checks entry frontmatter in the
background for field errors. Unchanged configuration/template content is
reused across controls and entry edits. Frontmatter checks still require
entry reads; ordinary folder browsing does not discover every
collection’s file content.

## Latest unstaged-change review — 2026-09-07

- [x] Review collection settings, validation, autosave/error recovery,
entry creation, reserved-file actions, and conversion flows.
- [x] Review shared labels, list keyboard handling, dialog focus/Escape,
buttons, and panel spacing migrations.
- [x] Fix Enter/Space list activation lost when arrow navigation
replaced the existing press handler.
- [x] Recognize historical generated ASCII/Unicode slug patterns, use
the bundled Unicode slug schema, and save a locally resolved $ref
without changing existing filenames.
- [x] Prevent duplicate slugless entries after a lost response: New
entry sends a stable UUID per attempt, reused by the repository's
existing filename/content retry checks. No database migration. Callers
omitting the optional requestId retain the previous behavior.
- [x] Preserve Content Block template validation independently of page
HTML placement, without accepting invalid rendered nesting.
- [x] Demonstrate the new review regressions fail without their fixes
and pass afterward.
- [x] Review authoritative documentation and update legacy slug
behavior.
- [x] Run fixtures and inspect generated changes: none.
- Deferred manual verification: Storybook screenshots were not
authorized for this pass.
- Historical evaluation status: not run in this pass; superseded by the
final verification section above.

## Verification

Local checks for commit **2b8195692e**:

- Builder app: 1,739 tests; Builder core: 1,150 tests. After the final
fixes, entry/settings tests and shared asset REST checks also passed,
including the added stable-retry test.
- Content Engine: 535 tests.
- Asset Uploader: 279 tests.
- Design system: 249 tests.
- Project Build: 2,392 tests.
- All five affected package typechecks, changed-file lint/formatting,
package boundaries, and Content Engine documentation tests passed.
- Complete fixture link/sync/build pipeline passed with no tracked
fixture changes.
- Staged diff and credential-pattern checks passed. No database schema,
migration, or generated database type changes. The lockfile includes the
collection validator and filename matcher dependencies.
- CI for this commit is pending. Builder E2E, manual
screen-reader/mobile checks, Storybook screenshots, and agent
evaluations were not run in this pass.

## MDX editing review — commit c3702a7238

- [x] Review all 36 local changed files: MDX parsing/materialization,
template enforcement, mutation commits, persistence, Assets refresh,
Navigator, source binding, editor diagnostics, dialogs, and query menus.
- [x] Validate new custom components at the shared Builder mutation
commit before applying tree changes. Cover move, reparent, paste, nested
paste, duplicate, and batched operations; preserve unchanged authored
content.
- [x] Match template names and component structure, including renamed
templates, instead of accepting any component type found in Templates.
- [x] Remove the registered-component fallback from MDX materialization
and completion; report untemplated JSX in the editor.

body for fresh unconnected Content Blocks.
- [x] Resolve Navigator's MDX-file action from the active content root
for dynamic sources.
- [x] Fix the first dialog drag jump while honoring subsequent explicit
size changes; contain long query menus and prevent editor Backspace from
deleting instances.
- [x] Demonstrate new review regression failures before the fixes and
passing results afterward.

## Local-change review — 2026-09-08

- [x] Review all 47 changed files and trace collection setup, filename
filters, public metadata/upload APIs, sync patches, Content-mode write
targets, local folder persistence, and MCP downloads.
- [x] Fix ignored MDX files being renamed into entries through the
metadata API. Selected filenames require New entry.

browser tests (279), plus expression tests and documentation checks.
- [x] Pass seven affected package typechecks, repository lint,
formatting, package boundaries, and fixture link/sync/build. No
generated fixture changes or database migration.
- Historical evaluation status: deferred in this pass; the user
subsequently authorized the full suite. See the final verification
section above.

Oleg Isonen 4273b7001f refactor: Organize Builder development and test tooling (#6285)
## Outcome

Builder development, backend, E2E, and CI tooling now share one
ownership model: Builder defines named commands and backend modes, while
CI only schedules those commands.

## Technical choices

- Group shared Compose files, PostgreSQL initialization, and backend
helpers under `apps/builder/backend`.
- Resolve `compose.<mode>.yaml` by convention instead of maintaining
Compose filename lists in scripts and workflows.
- Keep persistent development and disposable test Compose projects
separate by default, while allowing the standard `COMPOSE_PROJECT_NAME`
override.
- Make schema snapshots invalidate from discovered migration sources and
backend files.
- Move E2E behavior recipes into named Builder commands; retain concise
root proxies for developer entry points.
- Let Vitest allocate available browser ports instead of maintaining a
cross-package port registry.
- Keep test-suite scheduling explicit in `main.yml`, but move executable
test commands to root package scripts.
- Move fixture-size enforcement from inline GitHub JavaScript into a
locally runnable repository script.

## Todo

- [x] Consolidate Builder backend and Compose ownership.
- [x] Add named development, E2E, schema-cache, Supabase, and CI-shard
commands.
- [x] Remove Compose topology and behavior flags from CI.
- [x] Remove the static Vitest browser-port registry.
- [x] Extract fixture-size checking from the workflow.
- [x] Verify migration bootstrap, snapshot-backed E2E, tests, builds,
types, formatting, lint, generated contracts, and workflow syntax.
- [x] Review documentation impact: updated the E2E developer guide; no
user-facing `docs/` content is affected.

## Verification

- Full package, CLI, Builder core, and Builder app test suites
- Full workspace typecheck
- Builder production build
- Schema-cache generation through the complete migration history
- Supabase migration compatibility
- Snapshot-backed Playwright animation workflow
- Backend regression tests, including demonstrated fail/pass coverage
- All four Compose mode configurations
- `oxfmt`, `oxlint`, package boundaries, generated API, and generated
docs checks
- `actionlint` and Bash syntax checks

The fixture-size checker preserves the existing Linux `du` thresholds.
Its three inputs build locally; macOS allocation sizes are not directly
comparable to the Linux CI thresholds, so CI remains the authoritative
size result.

Oleg Isonen 8718feb465 test: simplify browser testing infrastructure (#6271)
## Summary

Unifies frontend testing around three intentional boundaries:

- Vitest Node projects for pure and server tests
- Vitest Browser Mode with Playwright/Chromium for DOM and component
tests
- Playwright Test for Builder end-to-end workflows

The Builder no longer uses jsdom. Ordinary E2E workflows use an
automatically managed isolated `page` fixture; explicit contexts remain
only for simultaneous identities and suite-scoped setup.

## Technical choices

- Split Builder tests into one Node project and independent browser
projects so each Chromium/Vite process has a bounded workload.
- Added shared Browser Mode configuration for the affected SDK React
packages.
- Preserve the Builder's production top-window bridge ownership; Browser
Mode uses explicit test-only installation seams.
- Centralized Playwright context options and kept action/navigation
timeouts bounded.
- Validate Playwright filters before Docker, migrations, browser
installation, or Builder builds start.
- Preserve the first failed E2E attempt's report, traces, screenshots,
and videos when CI retries a shard.
- Split static checks, typechecks, CLI tests, core package tests,
browser package tests, and Builder projects into parallel CI jobs with
five-minute hard ceilings.
- Distribute Builder E2E tests across ten isolated shards with two
workers; parallel suites create unique per-worker setup data.
- Reuse color contrast DOM/canvas samples so the exhaustive theme sweep
takes about four seconds instead of timing out at 30 seconds.
- The removed cost is jsdom behavior drift, oversized serial check jobs,
and unnecessary E2E startup for empty selections. Real browser startup
and E2E environment setup remain.

## Todo

- [x] Split Builder pure/server tests from browser/component tests.
- [x] Migrate Builder DOM tests from jsdom to Vitest Browser Mode.
- [x] Migrate affected SDK React DOM tests to the shared Browser Mode
setup.
- [x] Remove jsdom annotations, dependencies, and compatibility setup.
- [x] Replace ordinary manual E2E contexts with the isolated `page`
fixture.
- [x] Keep explicit contexts only for concurrent identities and
`beforeAll` setup.
- [x] Preserve setup authentication isolation from workflow pages.
- [x] Add bounded Playwright action and navigation timeouts.
- [x] Preserve first-attempt E2E failure evidence across CI retry.
- [x] Reject empty E2E selections before expensive environment setup.
- [x] Parallelize repository checks into bounded CI shards.
- [x] Isolate parallel E2E setup data across workers.
- [x] Remove the color contrast sweep bottleneck.
- [x] Update E2E contributor documentation.
- [x] Review product documentation impact; no user-facing product docs
are affected.
- [x] Run the full repository tests and typechecks.
- [x] Run formatting, lint, package-boundary, generated-file, and
fixture checks.
- [x] Complete final correctness and simplification review.

## Verification

- `pnpm --filter @webstudio-is/builder test`
- `pnpm -r typecheck`
- `pnpm lint`
- `pnpm check:package-boundaries`
- `pnpm check:generated-api`
- `pnpm check:generated-docs`
- `pnpm fixtures`
- Design-system: 222 tests pass locally.
- Builder: all seven Vitest projects pass locally.
- The formerly slow E2E shard passes locally in 1m55s.
- Full database-backed Builder E2E execution passes in CI.
- All CI jobs pass; the slowest completed in 4m58s.
- No fixture inputs/outputs or generated files changed.

Oleg Isonen f6c524572d feat: add Builder dark theme and rebuild colors
## Summary

Rebuilds Webstudio’s color system, migrates the entire Builder to it,
and introduces a complete dark theme.

A small set of theme colors and contrast controls now drives the
interface through relative CSS colors:

```text
Theme colors and contrast
    ↓
Light/dark derivation bounds
    ↓
Derived color families
    ↓
Reusable semantic colors
    ↓
Component composition
    ↓
Builder interface
```

CSS is the runtime source of truth. Light and dark modes share the same
theme inputs, so changing a theme color automatically updates its
surfaces, content, borders, states, and component presentation. The
refactor turns dark mode into a first-class Builder theme rather than a
separately maintained palette.

This is an atomic migration. Legacy color names and compatibility
aliases will not remain after all consumers have moved.

## Scope

- The color source, derivation model, semantic vocabulary, validation,
typing, and Storybook overview.
- Every design-system component.
- Builder, dashboard, authentication, shared UI, Query Builder, stories,
and tests that consume the legacy color scale.
- Removal of the legacy Stitches color scale after its final consumer is
migrated.
- A complete dark theme across application UI while keeping authored
canvas content independent.
- Complete light and dark visual verification.
- Unified browser-test infrastructure: Vitest Browser Mode for Design
System browser contracts and standard Playwright Test for all Builder
E2E workflows.

Literal colors remain only where color is the actual content or belongs
to a deliberately separate system, such as user-authored values,
external previews, brand artwork, data visualization, functional canvas
overlays, and source assets. Every remaining exception must have an
explicit owner.

## Architecture decisions

- Theme authors control six color families and three bounded contrast
controls.
- Relative CSS colors derive the rest of the system.
- Dark mode changes derivation bounds instead of maintaining a second
independent palette.
- Components consume a small reusable semantic vocabulary.
- Component states and exceptional presentation are composed inside
components.
- Builder-specific categorical meaning uses focused composite recipes,
not intent semantics or a larger global vocabulary.
- TypeScript validates public semantic CSS-variable names but does not
generate runtime colors.
- No token-manager dependency, compatibility aliases, or
component-specific public color tokens.
- A new semantic or theme variable is added only when existing semantics
and local composition cannot represent a reusable cross-feature
decision.

## Todo

### Color-system foundation

- [x] Establish direct CSS as the runtime source of truth.
- [x] Define bounded theme colors and contrast controls.
- [x] Derive light and dark modes from the same theme inputs.
- [x] Reduce the semantic inventory to reusable decisions and explicit
accessibility pairs.
- [x] Generate only TypeScript names for public semantic CSS variables.
- [x] Validate layers, references, cycles, consumption, naming,
generated types, and browser-computed contrast.
- [x] Add the Storybook color-system overview and theme controls.
- [x] Document the architecture and its relationship to the public Craft
specification.

### Design-system migration

- [x] Add complete positive, negative, warning, informative, and accent
accessibility pairings.
- [x] Validate light and dark scheme-bound references independently.
- [x] Verify the design-system package with typecheck, lint, formatting,
Storybook, and 222 tests.

### Inventory and contract

- [x] Inventory all 319 legacy references across 107 Builder, Query
Builder, story, test, and design-system files.
- [x] Classify every reference as a direct semantic replacement, local
composite recipe, documented literal exception, or removable code.
- [x] Record the intentional authored-content, external-preview,
functional-preview, data-visualization, brand, and source-asset
exceptions.
- [x] Treat the public semantic vocabulary as closed by default and
justify any proposed addition by cross-feature reuse and accessibility
need.
- [x] Keep Builder code limited to typed public variables accepted by
`cssVar()`.

### Theme infrastructure

- [x] Add `system` (default), `light`, and `dark` application
preferences.
- [x] Persist the preference in existing client settings and resolve
`system` through `matchMedia`.
- [x] Apply the resolved scheme before paint and respond to
operating-system changes.
- [x] Expose the persisted theme control under **View → Color scheme**.
- [x] Keep authored canvas documents independent from the application
theme.
- [x] Ensure portals, overlays, embedded surfaces, and third-party
controls receive the correct interface scheme.

### Generic interface migration

- [x] Migrate shared dialogs, project settings, notifications, controls,
and Query Builder.
- [x] Migrate dashboard, authentication, publishing, and shared
application UI.
- [x] Migrate the Builder loading state, topbar, sidebars, navigator,
workspace, footer, settings, pages, alerts, and menus.
- [x] Replace fixed interface literals alongside their owning surfaces.
- [x] Remove the old scrollbar variable and hardcoded loading color.

### Style panel and style-source recipes

- [x] Migrate ordinary style-panel inputs, labels, layouts, spacing,
alignment, menus, property states, and value editors.
- [x] Model style-source provenance, kind, interaction, and error as
separate axes.
- [x] Compose categorical style-source colors from neutral and
accent-relative colors.
- [x] Use negative semantics only for actual errors, not overwritten
provenance.
- [x] Reuse one feature-owned recipe across style-source controls,
badges, menus, and values without adding global tokens.

### Canvas and editors

- [x] Migrate canvas selection, reusable outlines, grid guides, resize
handles, labels, badges, and overlays.
- [x] Keep collaborator colors as data visualization while guaranteeing
readable labels.
- [x] Prevent Builder theme values from leaking into authored content.
- [x] Migrate editor surfaces, selections, autocomplete, lint states,
and tooltips.
- [x] Derive syntax visualization from neutral and accent-relative
colors; reserve intent colors for diagnostics.

### Explicit color domains

- [x] Isolate external search and social previews from the application
scheme.
- [x] Preserve user-authored CSS values, functional color previews, and
checkerboards.
- [x] Review brand surfaces independently in both schemes.
- [x] Document every retained literal in the exception ledger.

### Stories, tests, and legacy removal

- [x] Migrate all affected Builder stories and tests.

### Browser-test infrastructure

- [x] Run pure Design System tests in Node and browser-dependent tests
in Vitest Browser Mode with Playwright Chromium.
- [x] Migrate all 79 Builder E2E workflows from the custom harness to
standard Playwright Test.
- [x] Replace filename-based shard discovery with standard Playwright
sharding.
- [x] Preserve clean-backend shard retries and upload Playwright failure
artifacts in CI.
- [x] Remove the custom runner, registry, and timeout infrastructure.

### Verification and documentation

- [x] Compare light-mode visual regressions directly with `main`; review
every difference rather than accepting snapshots wholesale.
- [x] Add representative dark coverage for dashboard, Builder shell,
style panel, dialogs, editors, canvas tools, and status states.
- [x] Test default and extreme custom-theme presets.
- [x] Verify semantic and categorical-recipe contrast.
- [x] Test first paint, persistence, system changes, portals, and canvas
isolation.
- [x] Run affected tests, typechecks, lint, formatting, and Storybook
checks.
- [x] Review fixture impact; no fixture inputs or generated outputs are
affected.
- [x] Review authoritative `docs/` content and update it where needed.
- [x] Review the final diff and make this checklist reflect delivered
scope.

Oleg Isonen 2ec78c183d feat: Add single-result modes to Assets queries (#6040)
## Summary

- Add `many`, `one`, `first`, and `last` result modes to Assets queries
while keeping `many` as the backward-compatible default.
- Return direct items for single-result modes, validate deterministic
ordering, and report duplicate `one` matches as a structured
`MULTIPLE_RESULTS` error.
- Update Builder controls, preview/published runtime handling, SDK
resource encoding, MCP/CLI guidance, generated contracts, and fixtures.

## Implementation TODOs

- [x] Add result-mode schemas and core execution behavior.
- [x] Select single results before content hydration and preserve
deterministic ID tie-breaking.
- [x] Add structured duplicate-match transport errors.
- [x] Update Builder controls and hide/reset pagination for
single-result modes.
- [x] Keep existing settings first, then Output and Result, without a
duplicate Return label.
- [x] Preserve legacy saved resources with an implicit `many` default.
- [x] Update preview, published runtime, SDK, protocol, MCP, and CLI
behavior.
- [x] Regenerate runtime contracts, server metadata, CLI docs, and
fixtures.
- [x] Review documentation impact and update the authoritative MCP/CLI
guidance.
- [x] Add regression coverage and verify the new tests fail without the
implementation.
- [ ] Run the agent evaluation suite (not run; requires explicit user
approval).

## Compatibility and behavior

- Existing queries without `result` continue to behave as `many` and
retain the ID-keyed collection shape.
- `one` returns an item or `null`, but fails when more than one asset
matches.
- `first` and `last` require explicit sorting; the existing asset-ID
tie-breaker makes equal sort values deterministic.
- Single-result modes ignore and do not persist pagination controls.
Materialized collection queries remain collection-only; single-result
queries execute dynamically.

## Verification

- Content engine typecheck and full test suite (291 tests).
- Query builder, query-builder React, SDK, protocol, asset uploader,
project build, Builder, and CLI targeted typechecks/tests.
- Root lint.
- MCP documentation tests, typecheck, sync check, and generated-doc
checks.
- Generated API contract checks.
- Fixture generation pipeline.
- Final focused content-engine regression run (53 tests).
- Final DRY review: affected typechecks, focused tests, lint, package
boundaries, generated checks, and fixtures.

Oleg Isonen efbc3098c4 feat: add queryable Assets resources (#5946)
Closes #5919
Ref #5920

## Outcome

Extend the existing Assets system resource with optional queries for
Markdown, JSON, and standard file metadata. Unconfigured Assets
resources retain the existing fetch-all behavior and activate none of
the content-query infrastructure.

Files are the authoring model. A standalone content engine converts an
immutable snapshot of only the files required by configured queries into
one bounded, deterministic runtime database. Builder preview, SSR, and
SSG use the same query semantics without requiring a database service
for a published site.

## Final architecture

```text
Markdown / JSON files
        │
        ▼
ContentSource adapter
(FS or Webstudio Assets)
        │ immutable snapshot
        ▼
ContentCompilationPlan
(union of configured query requirements)
        │
        ▼
ContentCompiler
(parse, normalize, discover fields, enforce budget)
        │
        ▼
ContentArtifact
(bounded, deterministic, immutable JSON)
        │
        ▼
ContentDatabase
(filter, OR groups, sort, paginate, project, read content)
        │
        ├── Builder preview
        ├── SSR runtime
        └── SSG build only
```

The authoring/storage layer owns mutable files. The content engine
consumes immutable snapshots and produces immutable, disposable
artifacts.


Query authoring is a separate OpenAPI-driven path:

```text
Assets REST OpenAPI operation
+ standard request JSON Schema
+ dynamic field paths
        │
        ▼
Generic OpenAPI adapter
        │ resolved schemas, controls, paths, and transport mapping
        ▼
Generic query-builder core and React renderer
        │ arbitrary provider-defined value
        ▼
Assets REST request adapter
        │
        ▼
{ query: value }
```

The selected standard OpenAPI operation is the only source of query UI
semantics. Request parameters and JSON Schema describe the editable
data; the generic renderer derives controls and owns layout.

### Activation and compilation

- The compiler does not index every asset. It combines all reachable
configured Assets-resource queries into one `ContentCompilationPlan`.
- Static constraints such as folder, path, and file type select
candidate files. Dynamic values such as a route-bound slug cannot reduce
the build-time candidate set.
- The plan contains the union of fields used by filtering, sorting,
routing, projection, excerpts, and requested full content.
- Documents shared by multiple resources are stored once in one
deployment-wide runtime database.
- Markdown/frontmatter, JSON properties, excerpts, and full bodies are
prepared only when required.
- No configured content query means no parsing, artifact, or shipped
runtime dependency. Fresh generated apps need no content-runtime
cleanup; incremental generation removes stale integration if a
previously configured query is deleted.

### Runtime database limit

- `CONTENT_DATABASE_MAX_BYTES` limits the complete serialized runtime
database, not source files, images, or unrelated assets.
- The default is `500 * 1024` bytes and is presented as 500 KiB.
- Counted data includes indexed metadata, frontmatter/JSON properties,
excerpts, the field catalog, serialization overhead, and full Markdown
bodies only when requested.
- Prepublish validation builds and serializes the exact database that
will be attached to the immutable build, so it knows the unbounded size,
bounded size, included documents, omitted documents, and affected
resources.
- Overflow never stores partial documents. Candidates are ordered by
`createdAt` descending, canonical path ascending, and stable document ID
ascending. Missing dates follow dated documents. A document that does
not fit is skipped while smaller later documents are still considered.
- Exceeding the limit warns but does not block publishing.
- Builder preview can report exact bounded versus unbounded results when
dynamic expressions have concrete preview values. Prepublish warnings
remain conservative for future route values.

### Snapshot consistency

The source contract guarantees a consistent compilation, while adapters
provide the mechanism:

- Webstudio Assets captures asset metadata and immutable content
references.
- Filesystem sources capture file identity and verify files did not
change before accepting the artifact.
- A changed source retries once, then fails clearly instead of producing
a mixed-revision database.
- This requires no universal snapshot service, source-tree copy, or new
versioned-asset infrastructure.

### Package ownership

- `@webstudio-is/content-engine`: runtime artifact schema, query
execution, field catalog, compact runtime statistics.
- `@webstudio-is/content-engine/compiler`: source snapshots, compilation
plans, Markdown/JSON parsing, deterministic compilation, byte
accounting, and compiler diagnostics. This entry exists to keep
Remark/YAML/future MDX dependencies out of runtime bundles.
- `@webstudio-is/query-builder`: resolves standard OpenAPI operation
schemas into an internal provider-neutral editor model, validation,
mutations, and source serialization. It owns no Assets,
provider-authored UI contract, or fixed REST-query semantics.
- `@webstudio-is/query-builder/react`: container-neutral schema renderer
whose layout is renderer policy. It remains separate from the content
engine.
- SDK: Webstudio Assets/Resource domain models and mapping Webstudio
expressions into generic content requirements.
- Protocol: external Assets REST/OpenAPI transport contracts.
- Asset uploader/repository: asset and folder mutations, generic
metadata, immutable byte references, and storage access. Its hosted
adapter supplies Webstudio Assets snapshots and parsed-metadata cache
persistence to the content engine; parsing, artifact creation, and query
semantics remain engine-owned.
- Builder and generated-app integrations decide when to compile, cache,
embed, load, or discard a database.

### Runtime lifecycle

- Builder caches immutable `ContentDatabase` instances by source
revision plus compilation-plan hash and coalesces concurrent
compilation. Matching operations reuse the same instance; field
discovery uses a dedicated minimal all-properties plan that excludes
excerpts and bodies.
- SSR attaches the validated bounded database to the build and includes
the small runtime only when required.
- SSG uses the database only while generating pages and omits it and the
runtime from final output unless a future runtime-query feature requires
them.
- Local development compiles from the filesystem and uses identical
query semantics.
- Published pages query their local artifact; they do not call Builder
REST endpoints.
- Published artifacts need no external index store, invalidation,
garbage collection, SaaS content proxy, new bucket, or new environment
variable.

## Implemented foundation

These existing parts remain useful and should be moved behind the final
ownership boundaries rather than reimplemented.

- [x] Upgrade the existing Assets system resource in place and preserve
unconfigured fetch-all behavior.
- [x] Implement typed filtering, nested boolean groups, deterministic
sorting, pagination, projections, dynamic values, and content hydration.
- [x] Add Markdown frontmatter, excerpt, JSON-property, and
field-catalog extraction.
- [x] Add reusable query-control implementations and a separately
imported React UI as a foundation for the final OpenAPI-driven contract.
- [x] Add Assets query authoring and dynamic field discovery as existing
behavior to migrate into the Assets OpenAPI operation.
- [x] Add synchronized visual and editable expression authoring.
- [x] Unify Assets REST operations under `/rest/assets/*`.
- [x] Define authenticated collection, item, content, upload, folder,
query, field-catalog, and OpenAPI operations.
- [x] Support Builder cookie authentication and public API token
authentication.
- [x] Add Builder preview, MCP/CLI operations, SSR execution, SSG path
generation, and conditional activation.
- [x] Add revision-keyed parsed metadata persistence for the hosted
Builder.
- [x] Add focused query, API, authorization, Builder, CLI, SSR, SSG,
migration, and fixture coverage.

## Remaining implementation plan

### 1. Establish the content engine

- [x] Rename the generic `@webstudio-is/asset-resource` implementation
to `@webstudio-is/content-engine`.
- [x] Move existing behavior instead of creating a parallel
implementation.
- [x] Keep the primary entry runtime-only and add only the compiler
entry needed for bundle separation.
- [x] Remove the old package after all consumers migrate.
- [x] Ensure the engine has no Builder, SDK, asset-uploader, PostgreSQL,
R2, or deployment-target dependency.

### 2. Define source snapshots and compilation plans

- [x] Introduce `ContentSource.openSnapshot()` and a revision-bearing
`ContentSourceSnapshot`.
- [x] Include canonical path, stable document ID, content type,
immutable content reference, size, and optional `createdAt`.
- [x] Implement Webstudio Assets and filesystem snapshot guarantees
using their adapter-specific mechanisms.
- [x] Introduce `ContentCompilationPlan` for the union of reachable
configured resource requirements.
- [x] Separate statically selectable candidates from dynamic runtime
predicates.
- [x] Add mutation-during-compilation tests for replacement, deletion,
folder movement, and filesystem changes.

### 3. Separate storage from content processing

- [x] Keep upload, replacement, folders, byte storage, revisions, and
generic metadata in the Assets repository/uploader.
- [x] Move parsing, excerpts, field discovery, query execution, and
artifact creation into the content engine.
- [x] Remove content-index coordination from asset mutation business
logic.
- [x] Preserve original source `createdAt` across content replacement
and expose it as optional queryable metadata.
- [x] Keep hosted parsed-document persistence behind the content
compiler's optional cache interface.

### 4. Build deterministic compilation

- [x] Move the existing Markdown, frontmatter, JSON, canonicalization,
hashing, document-building, and tests into the compiler.
- [x] Keep frontmatter behind a dedicated module and continue using the
existing Remark/Micromark pipeline.
- [x] Parse only candidate files and only the tiers required by the
compilation plan.
- [x] Deduplicate documents and fields required by multiple resources.
- [x] Define a versioned, deterministic `ContentArtifact` with integrity
information.
- [x] Keep verbose parse and omission diagnostics outside the runtime
artifact.
- [x] Reject incompatible artifact versions cleanly.

### 5. Enforce the deployment-wide database budget

- [x] Replace the old asset-index limit with
`CONTENT_DATABASE_MAX_BYTES`, defaulting to 500 KiB.
- [x] Have applications read configuration and pass the byte limit into
the compiler.
- [x] Measure the exact serialized database, including selected bodies
and overhead.
- [x] Implement deterministic skip-and-continue packing of complete
documents.
- [x] Return compiler diagnostics with unbounded/bounded bytes,
included/omitted counts, omitted identities, largest contributors, and
affected resources.
- [x] Expose only compact artifact statistics at runtime through
`ContentDatabase.getStats()`.
- [x] Add exact boundary, deterministic ordering, deduplication, and
oversized-document tests.

### 6. Finalize the runtime database

- [x] Define `ContentDatabase` over an immutable artifact.
- [x] Preserve filtering, nested AND/OR groups, sorting, offset/limit,
projection, field references, and content retrieval.
- [x] Expose `getFieldCatalog()` and compact `getStats()`.
- [x] Keep Markdown/YAML/compiler dependencies out of the runtime entry.
- [x] Add execution guards and maximum-size runtime benchmarks.

### 7. Make query authoring OpenAPI-driven

The selected standard OpenAPI operation is the complete query-authoring
contract. The query builder resolves parameters and request-body JSON
Schema, derives its internal editor model, and applies renderer-owned
layout policy. It must not embed or fetch a second capabilities/UI
language through `x-webstudio-query` or another side channel.

- [x] Remove `x-webstudio-query` and all vendor query-definition
metadata from the Assets OpenAPI operation.
- [x] Resolve local OpenAPI references and derive the editable request
value, defaults, validation, labels, choices, arrays, objects, and
unions solely from standard operation parameters and request-body JSON
Schema.
- [x] Represent dynamic Assets field paths with standard JSON Schema
vocabulary in the `queryAssets` request schema.
- [x] Keep the normalized editor representation internal to
query-builder; do not expose another provider-authored capabilities
contract.
- [x] Remove provider-controlled layout metadata such as `group`; make
compact scalar packing and all other layout renderer policy.
- [x] Keep Webstudio expression binding as a consumer/editor concern
layered over schema values, not part of the OpenAPI contract.
- [x] Preserve the existing Assets filter, sort, output selection,
full-content/range selection, limit/offset, editable source, and
configured-field behavior.
- [x] Keep the Assets resource adapter responsible for serializing the
edited query into its request body.
- [x] Remove the obsolete Assets query-capabilities endpoint, URL, and
UI-side capability parsing.
- [x] Add a non-Assets OpenAPI proof with differently named parameters
and no vendor metadata.
- [x] Verify the generic packages contain no Assets imports, fixed
Assets property contract, or provider-authored layout model.
- [x] Update focused core, React, SDK, protocol/OpenAPI, Builder, and
source round-trip tests.

### 8. Manage ContentDatabase lifecycle in Builder

- [x] Cache databases by source revision plus normalized
compilation-plan hash.
- [x] Coalesce concurrent compilation requests.
- [x] Reuse cached database instances across field discovery,
autocomplete, query preview, and response preview when their normalized
compilation plans match.
- [x] Replace it when source revision or query requirements change.
- [x] Preserve the optional revision-keyed hosted parsed-document cache
without making it a source of truth.
- [x] Show exact preview warnings when concrete values reveal missing
bounded results.

### 9. Materialize and verify immutable builds

- [x] Compile and serialize the exact deployment-wide database during
prepublish validation.
- [x] Attach that validated bounded database to the immutable build
without rebuilding it from later asset state.
- [x] Show non-blocking prepublish warnings with database bytes,
omissions, and potentially affected resources.
- [x] Avoid claiming exact future route matches when dynamic values are
unknown.
- [x] Include the database/runtime only when a reachable configured
query requires them.
- [x] Ensure detail resources requesting Markdown content include all
statically eligible bodies needed by dynamic routes.

### 10. Integrate all targets

- [x] SSR: load the build's bounded database and conditionally include
the small runtime.
- [x] SSG: query the same database during generation, then omit
database/runtime output when no runtime query is needed.
- [x] Local/CLI: compile from the filesystem source with the same
semantics.
- [x] Preserve overview pagination, alternative route fields,
draft-as-user-data behavior, and full article rendering.
- [x] Verify ordinary Assets and fresh query-free sites perform no
parser, artifact, content-runtime dependency install, or cleanup work.

### 11. Correct API and package ownership

- [x] Move external Assets REST/OpenAPI contracts to
`@webstudio-is/protocol`.
- [x] Keep Webstudio domain models and Assets system-resource
configuration in the SDK.
- [x] Keep both cookie and token authentication behavior on the unified
Assets REST surface.
- [x] Remove pass-through route wrappers/reexports that add no transport
behavior.
- [x] Keep published runtime queries local to the artifact rather than
routing them through Builder REST.

### 12. Remove superseded deployment infrastructure

- [x] Remove external deployment-index upload, fetch, invalidation,
cleanup, and garbage-collection code.
- [x] Remove the SaaS asset-origin adapter requirement; close
webstudio-is/webstudio-saas#652 as superseded because it has no
independent purpose.
- [x] Remove index-bucket compatibility configuration and avoid adding
Infisical variables.
- [x] Remove obsolete external-index paths, package dependencies,
routes, scripts, and tests.
- [x] Consolidate unreleased intermediate migrations where safe and
retain only schema required by the final hosted cache/API design.

### 13. Verification and release readiness

- [x] Move and preserve existing tests while changing ownership; add new
tests only for changed contracts and behavior.
- [x] Run content-engine compiler/runtime tests, query-builder tests,
SDK/protocol/API tests, Builder tests, CLI tests, and affected
typechecks.
- [x] Run formatting, generated-file idempotence, fixtures, clean
Supabase-compatible migrations, E2E shards, and complete agent
evaluations.
- [x] Verify SSR and SSG conditional inclusion and query-free generated
package manifests.
- [x] Run the five-article MCP blog workflow: authoring, field
discovery, overview, dynamic detail routes, full Markdown rendering,
publishing, and published-site verification.
- [x] Run a maximum-budget database test and a
mutation-during-compilation test.
- [x] Perform a final architecture, security, API compatibility,
migration, bundle, correctness, and DRY review.
- [x] Reconcile every checkbox and replace the verification section with
results from the final architecture before release.

## Future MDX work

MDX is intentionally separate from this release.

- The compiler contract should allow a future build-only MDX parser.
- MDX compilation must not enter the published runtime.
- Embedded JSX must use an explicit compiled representation rather than
runtime source evaluation.
- Webstudio components, tokens, styles, and component allowlists remain
Webstudio integration concerns.
- The future MDX work should reuse `ContentArtifact` and
`ContentDatabase` where practical.

## Superseded design

The following earlier design choices are no longer the target
architecture:

- GROQ or GraphQL as the Assets query language.
- One external or long-lived index object per resource/query.
- A deployment index fetched by the Worker from SaaS/CDN infrastructure.
- Lazy production reads of source Markdown bodies.
- A separate index bucket, asset origin, invalidation service, or
garbage collector.
- A 4 MiB published index limit.
- Rebuilding an old build's database from the current mutable asset set.
- Bundling query infrastructure into projects without a configured
content query.

## Verification baseline

The embedded runtime-database architecture previously passed the checks
below. The OpenAPI-driven query-authoring change additionally passed:

- Query-builder core: 4 files / 19 tests.
- Query-builder React: 1 file / 7 tests.
- SDK Assets source/config: 1 file / 7 tests.
- Protocol Assets OpenAPI: 1 file / 9 tests, including independent
OpenAPI validation.
- Builder Assets OpenAPI description: 1 file / 5 tests.
- Query-builder, React, SDK, protocol, and Builder typechecks.
- Package-boundary validation and formatting of every affected file.

Local verification baseline:

- Content engine: 15 files / 104 tests.
- Asset uploader: 24 files / 175 tests.
- Builder: 204 files / 2,423 tests.
- CLI: 54 files / 866 tests.
- Complete workspace typecheck, formatting, lint, package boundaries,
generated fixtures, and fixture builds.
- The complete migration history applied successfully to a fresh
Supabase-compatible database, including every migration after the
consolidated Assets migration.
- Builder production build and full local E2E suite passed.
- Complete agent evaluations passed: authenticated page (170,859 ms),
design input (207,101 ms), and font assets (67,050 ms).
- Final review additionally verified correct REST edit/view/build
permits, cookie and public-token read paths, immutable snapshot retries,
exact database budgeting, query-free dependency omission, and SSR/SSG
conditional runtime inclusion.

Final staging verification passed against the embedded runtime-database
architecture: MCP uploaded and updated five Markdown articles,
discovered dynamic frontmatter fields, previewed a five-item sorted
overview and one full-body slug query, updated both Assets resources,
found zero binding issues, rendered `/blog` and `/blog/dynamic-routes`
at HTTP 200, published build version 266, and verified both published
routes at HTTP 200 with the expected article metadata and Markdown body.
The workflow also found and fixed offset-form asset timestamps failing
canonical datetime validation and made MCP `preview.start({ port: 0 })`
correctly select an available local port.

## Release constraints

- No new SaaS content service, bucket, or environment variable.
- No published-site database dependency.
- No parser/compiler dependency in query-free sites or runtime-only
bundles.
- The validated content database is immutable build output.
- Publishing warnings do not block deployment.
- The selected standard OpenAPI operation and its request JSON Schema
are the only source of query UI semantics.
