Summary

  • introduce versioned Forms as optional one-to-one presentations for Router endpoints while preserving headless endpoint URLs and bearer-token behavior
  • add draft authoring, starters, autosave conflicts, explicit publishing, hosted pages, approved-origin embeds, form-filtered leads, and shared transaction-backed lead acceptance
  • add signed render sessions, 64 KiB limits, unknown-field rejection, honeypot protection, hashed-IP/form rate limits, UTC monthly usage, attribution, and 80%/100% usage notices
  • add the WordPress 6.6+ block/shortcode integration and a downloadable plugin ZIP
  • replace scattered plan checks with Free, Pro, Business, and Enterprise entitlements; recognize legacy Stripe prices while providing a dry-run-first period-end migration command
  • add forward-only migrations, CI, release documentation, and browser verification evidence

Verification

  • pnpm typecheck
  • pnpm lint
  • pnpm test:unit — 113 passed; 10 database tests skipped in this command by design
  • fresh PostgreSQL 16: pnpm db:migrate then pnpm test:db — 10 passed through production services
  • credential-free pnpm build
  • pnpm check:server-actions
  • pnpm wordpress:check
  • pnpm wordpress:package plus ZIP integrity check
  • Playwright — 19 hosted/embed runtime scenarios, plus WordPress 6.6/current × block/classic theme coverage in CI (wp-env now runs PHP 8.2; the PHP 7.4 Debian bullseye image no longer builds)

Browser findings and evidence are in dogfood-output/report.md. Both findings discovered during the smoke were fixed in this PR.

Release gates

  • Forms navigation and endpoint CTAs default hidden with FORMS_NAV_ENABLED=false
  • public Forms have a rollback switch through FORMS_PUBLIC_ENABLED=false
  • apply migrations 0006 through 0018 before application activation
  • configure the form submission and cron secrets, usage-email settings, four new Stripe price IDs, and Stripe webhook secret
  • authenticated preview/UAT, forms.router.so attachment, real WordPress 6.6/current theme testing, plugin publication, and navigation exposure remain post-merge release gates
  • the legacy Stripe migration script is dry-run-only unless --apply is supplied; no subscriptions were mutated and no customer emails were sent as part of this PR

Rollback

Set FORMS_NAV_ENABLED=false and FORMS_PUBLIC_ENABLED=false. Do not roll back applied migrations. Existing endpoint APIs, leads, and webhooks remain unchanged.

See docs/forms/release-runbook.md for the ordered release and rollback procedure.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 426e9

This PR adds public form submission and new lifecycle, billing, integration, and CI behavior, but the current implementation can still duplicate leads and webhook deliveries, persist submissions across publication changes, fail unexpectedly during endpoint deletion, enable resource or rate-limit abuse, and expose CI credentials to pull-request code. These correctness, security, and availability risks should be fixed or explicitly accepted before merge.

346-355: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick win

Limit the MutationObserver work on busy host pages.

The observer watches document.documentElement with subtree: true. For every added element node it calls scan(node), and scan runs querySelectorAll over that whole subtree. On a host page with heavy DOM churn, such as a single-page application, an ad slot, or infinite scroll, this traverses large subtrees repeatedly for the lifetime of the page. The observer is also never disconnected.

Coalesce the mutations into one deferred scan of the document.

♻️ Proposed refactor
-  new MutationObserver(function (records) {
-    records.forEach(function (record) {
-      record.addedNodes.forEach(function (node) {
-        if (node.nodeType === 1) {
-          if (node.matches && node.matches("[data-router-form]")) mount(node);
-          scan(node);
-        }
-      });
-    });
-  }).observe(document.documentElement, { childList: true, subtree: true });
+  var scanQueued = false;
+  new MutationObserver(function (records) {
+    if (scanQueued) return;
+    var hasElement = records.some(function (record) {
+      return Array.prototype.some.call(record.addedNodes, function (node) {
+        return node.nodeType === 1;
+      });
+    });
+    if (!hasElement) return;
+    scanQueued = true;
+    requestAnimationFrame(function () {
+      scanQueued = false;
+      scan();
+    });
+  }).observe(document.documentElement, { childList: true, subtree: true });

mount already guards against duplicate initialization through the initialized WeakSet, so a single document-wide scan stays correct.

Enforce the body limit before buffering the whole payload.

The pre-check reads content-length. If the header is absent, the value is 0. If the header is not numeric, the value is NaN. Both cases skip the pre-check, so request.text() buffers the complete body before the second check rejects it. A chunked request with no content-length therefore allocates memory without bound until the read completes.

Read the body as a stream and abort when the accumulated size passes MAX_BODY_BYTES.

♻️ Proposed streaming limit
 async function readJsonBody(request: Request): Promise<unknown> {
-  const declaredLength = Number(request.headers.get("content-length") ?? 0);
-  if (declaredLength > MAX_BODY_BYTES) {
+  const declaredLength = Number(request.headers.get("content-length"));
+  if (Number.isFinite(declaredLength) && declaredLength > MAX_BODY_BYTES) {

Inline comments:
In @.github/workflows/ci.yml:
- Line 12: Add persist-credentials: false to each of the three
actions/checkout@v4 steps in the workflow, ensuring no checkout writes the
GITHUB_TOKEN to local Git configuration.

In `@app/api/public/forms/`[publicId]/leads/route.ts:
- Around line 62-65: Update the invalid-submit-token response in the leads route
to authorize the request origin before returning the 401, and attach CORS
headers only when that origin is approved; preserve the existing error payload
and status for rejected origins.
- Line 34: Replace the full-body request.text() handling in the leads route with
a shared streamed reader that enforces a 64 KiB limit before decoding; apply the
same reader to the render-session route’s full-body parsing. Update both
app/api/public/forms/[publicId]/leads/route.ts:34-34 and
app/api/public/forms/[publicId]/render-session/route.ts:26-26, preserving their
existing downstream parsing behavior.
- Line 25: Update clientIp in the request handling flow so enforceFormRateLimit
uses an ingress-authenticated client-IP source instead of directly trusting
X-Forwarded-For or X-Real-IP; alternatively, ensure every ingress strips and
replaces those headers before they reach the application. Preserve the per-IP
rate-limit behavior while preventing clients from rotating the key.

In `@app/api/webhooks/stripe/route.ts`:
- Line 74: Update the Stripe webhook handling around checkout.session.completed
and customer.subscription.deleted so delayed checkout events cannot restore a
canceled entitlement. Persist and compare subscription event state, or reject
checkout updates when the subscription is already in a terminal state, while
preserving valid checkout plan updates.

In `@components/groups/forms/create-form.tsx`:
- Line 97: Update the starter button rendering near the selected-state class
condition to include aria-pressed based on the same starterId === starter.id
comparison, exposing the active starter state to screen readers while preserving
the existing CSS styling.

In `@components/groups/forms/form-editor.tsx`:
- Around line 326-328: Update the origin deduplication in the state update
around addedOrigin so filtering matches both origin and kind, preserving an
existing WordPress record when replacing a generic embed origin with the same
value.

In `@lib/data/stripe.ts`:
- Around line 34-35: Update the Stripe URL construction around success_url,
cancel_url, and return_url to use the validated server-side ROUTER_APP_URL
instead of the request-derived protocol and host values, while preserving the
existing endpoint paths and query parameters.

In `@lib/forms/definition.ts`:
- Around line 363-368: Update the required branch in the number/slider schema
handling to reject an empty string before z.coerce.number() converts it to zero.
Preserve the existing optional-field preprocessing and min/max validation, while
ensuring blank required values fail validation.

In `@lib/forms/lead-acceptance.ts`:
- Around line 85-90: Update the fetch flow in the lead-acceptance submission
function to prevent SSRF: validate the parsed initial webhook URL and each
redirect target, rejecting private, loopback, link-local, and other disallowed
destinations before connecting. Disable automatic redirect following and
explicitly handle redirects so every Location target is validated before issuing
the next request, while preserving the existing POST payload, headers, timeout,
and error behavior.

In `@lib/forms/starters.ts`:
- Around line 110-136: Update seedDefinitionFromEndpoint to bound each derived
field key, id, and label before createForm validates the definition: truncate
the sanitized unique key to the supported key limit, ensure the generated
imported id remains within its id limit, and cap the display label at its label
limit while preserving uniqueness and existing defaults.

In `@public/embed/v1.js`:
- Line 248: Remove the name assignment from the honeypot input setup near
honeypotInput, leaving the input otherwise unchanged; its existing honeypotInput
reference is used for validation, so it must not contribute a field name that
can collide with real form fields.
- Line 130: Update the field input-generation logic around the required
assignment so the native input.required flag is set only for radio-group fields,
not checkbox-group fields. Add separate checkbox-group validation before
submission that considers the group satisfied when any checkbox is selected,
while preserving existing required behavior for radio groups.

Bound and order the retry batch.

The query selects up to 1,000 rows with no ORDER BY. Each row can produce two thresholds, so one invocation can perform up to 2,000 sequential email sends. Two effects follow:

  • The cron invocation can exceed the function time limit before it finishes the batch.
  • Rows that keep failing are re-selected on every run in an unspecified order, so they can crowd out newer pending rows.

Add a deterministic order, and use a batch size that fits the cron budget.

- Around line 26-36: Update the test around sendUsageThresholdNotification to
restore process.env.RESEND_API_KEY in a finally block, preserving the exact
original state by deleting it when originally unset and restoring the original
value otherwise, even if the assertion fails.

In `@app/api/cron/forms-maintenance/route.ts`:
- Line 7: Update the authorization check in the forms-maintenance route to
reject requests immediately when CRON_SECRET is unset or empty, before comparing
authHeader; retain the existing Bearer-token comparison for configured secrets.

In `@lib/forms/starters.ts`:
- Around line 124-130: Update hasUsableAllowedValues so each allowed value must
already equal its trimmed form, while retaining the existing non-empty, length,
and uniqueness checks. This prevents values such as surrounding-whitespace
options from being considered compatible before formDefinitionV1Schema
normalization.

In `@lib/forms/usage-notifications.ts`:
- Around line 104-111: Persist the usage count snapshot when stamping
notificationLimit80 or notificationLimit100, then use that persisted threshold
count as the used value in sendUsageThresholdNotification instead of mutable
claimed.used, keeping usageNotificationIdempotencyKey(input) stable across
retries.

- Use PHP 8.2 wp-env images; the PHP 7.4 (Debian bullseye) image can no
  longer build because the bullseye-security release file is gone
- Correct the release runbook migration range (0006 through 0018) and the
  schema checks operators must confirm
- Keep the legacy endpoint lookup inside the route try/catch so database
  failures return the JSON error contract instead of an unhandled 500
- Return CORS headers on early public-submission rejections for approved
  embed origins so widgets can read 400/401/413 responses
- Make endpoint deletion atomic with a row lock so a concurrent form
  attachment raises AttachedFormExistsError instead of a raw FK error
- Stop retrying draft saves on every keystroke after a revision conflict
- Warn inline when two fields share a submission key; add aria-pressed to
  starter buttons
- Set the WordPress site token before rendering in the smoke test so the
  token-leak assertion is meaningful; restore RESEND_API_KEY in finally
- Harden CI with persist-credentials: false and read-only token permissions
- Document the forwarded-IP trust assumption for rate limiting

Code review

Found 5 issues, all fixed in 7de62dd:

  1. The release runbook told operators to apply migrations 0006 through 0014, but the PR ships 0006 through 0018. Migrations 0015-0018 add user.stripeBillingInterval, the wordpress_connection_active_owner_site_unique index, and the formCacheInvalidation outbox table that every publish/unpublish/delete writes to, so following the runbook literally would deploy app code against an incomplete schema. (doc/code mismatch)

- Back up the target PostgreSQL database.
- Apply migrations `0006` through `0014` in order with `pnpm db:migrate`.
- Confirm `forms`, `formOrigins`, `wordpressConnections`, `usagePeriods`, `formRateBuckets`, and `formPlacementMilestones` exist.
- Confirm usage notification lease/limit columns, the Enterprise contract allowance columns, the Stripe subscription creation timestamp, and the form-lead lookup index exist; existing Enterprise accounts should have the compatibility allowance from `0013`.

  1. The legacy endpoint route now runs getPostingEndpointById outside the try/catch, so a database error surfaces as an unhandled 500 instead of the internal_error JSON contract. On main the whole handler was wrapped. (regression against main)

const endpoint = await getPostingEndpointById(id);
if (!endpoint) {
return NextResponse.json({ message: "Endpoint not found." }, { status: 404 });
}
if (endpoint.token !== authorization.slice("Bearer ".length)) {
return NextResponse.json(
{ message: "Unauthorized. Invalid token provided." },
{ status: 401 }
);
}
try {

  1. The public submission route returns 400/401/413 before computing CORS headers, so an approved embedded origin cannot read those responses. Submission tokens expire after 60 minutes, so a slow filler hits this and sees an opaque network error instead of invalid_submit_token. (bug)

token = verifySubmissionToken(parsed.submitToken);
} catch (error) {
return NextResponse.json(
{ error: "invalid_submit_token", message: error instanceof Error ? error.message : undefined },
{ status: 401 }
);
}
if (!submissionTokenMatchesRequest(token, { publicId, origin })) {
return NextResponse.json({ error: "invalid_submit_token" }, { status: 401 });
}

  1. deleteEndpointForUser checks for an attached form and then deletes in separate statements with no transaction or lock. A form attached in between makes the delete throw a raw foreign-key error instead of AttachedFormExistsError, which the caller does not translate. (race)

const [attachedForm] = await database
.select({ id: forms.id })
.from(forms)
.innerJoin(endpoints, eq(forms.endpointId, endpoints.id))
.where(
and(eq(forms.endpointId, input.id), eq(endpoints.userId, input.userId))
)
.limit(1);
if (attachedForm) throw new AttachedFormExistsError();
await database
.delete(endpoints)
.where(and(eq(endpoints.id, input.id), eq(endpoints.userId, input.userId)));
}

  1. The WordPress smoke test sets router_forms_site_token after rendering the markup it asserts against, so the token-leak assertion could never fail. (test integrity)

}
update_option("router_forms_site_token", "secret-test-token");
if (strpos($combined, "secret-test-token") !== false) {
fwrite(STDERR, "The site token leaked into frontend markup.\n");
exit(1);
}

The same commit also switches wp-env to PHP 8.2 (the PHP 7.4 Debian bullseye image no longer builds, which is why the wordpress-runtime jobs failed), and addresses the remaining CodeRabbit threads except the grace-limit comparison, which is intentional: __tests__/forms-db.integration.test.ts expects exactly graceLimit leads to be accepted before the period pauses. The webhook SSRF and Stripe Host-header findings describe behavior that already exists on main and are left for follow-up.

@vercel/postgres only speaks Neon's WebSocket protocol, so the README's
Docker workflow could not reach a plain PostgreSQL container. A dev-only
config points the driver at a local wsproxy when POSTGRES_WS_PROXY is set;
production deployments are unaffected.

next-auth skips its automatic sign-in redirect when auth() wraps a custom middleware function, which #45 introduced for the forms host rewrite. Return the redirect from the authorized callback instead, with a unit test.
