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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Webstudio Components for React Router

React Router adapters for Webstudio's React components.

Package boundary

Owns the React Router adapter layer. It connects production components to React Router lifecycle behavior. Keep generic component behavior in the component package and avoid duplicating shared behavior here.
