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 — 52 passed; database tests skipped in this command by design
  • fresh PostgreSQL 16: pnpm db:migrate then pnpm test:db — 3 passed
  • credential-free pnpm build
  • pnpm wordpress:check
  • pnpm wordpress:package plus ZIP integrity check
  • public runtime browser smoke: desktop/mobile, multiple forms, keyboard flow, accessible fieldsets/headings, reduced motion, and no horizontal overflow

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 0010 before application activation
  • configure the form submission secret, 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 93c47

This PR adds anonymous public submissions, embeds, maintenance jobs, and billing-related workflows, but the current head still has security and correctness risks that can enable unauthorized maintenance or resource abuse, create duplicate or rejected leads, and produce inconsistent usage or notification behavior. Merge should wait for the high-impact issues to be fixed or explicitly accepted by the appropriate security and product owners.

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) {
     throw new Response("Payload too large", { status: 413 });
   }

-  if (Buffer.byteLength(body, "utf8") > MAX_BODY_BYTES) {

+      await reader.cancel();
+      throw new Response("Payload too large", { status: 413 });
+    }
+    chunks.push(value);
   }

+  return JSON.parse(Buffer.concat(chunks).toString("utf8"));

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.

🌐 Web query:

actions/checkout v4 persist-credentials false README credentials persisted local git config

💡 Result:

In the actions/checkout action (including v4), the persist-credentials input determines whether the authentication token (or SSH key) used to fetch the repository is configured in the local Git configuration [1][2][3]. By default, persist-credentials is set to true [1][2]. When enabled, the action adds the credentials to the repository's local.git/config file (often via an http.extraheader) [1][4][5]. This allows subsequent steps in the same job to perform authenticated Git operations without needing to re-provide the token [1][3]. The action removes these credentials during the post-job cleanup [1][2][3]. Setting persist-credentials: false prevents the action from writing these credentials to the local Git configuration [1][6]. This is a recommended security best practice for workflows that do not require the ability to push commits or perform other authenticated Git operations, as it prevents other steps or third-party actions within the same job from potentially accessing or misusing the token [4][6][5][7]. Summary of behavior: - Default (true): Credentials are written to.git/config during checkout and removed during post-job cleanup [1][2]. - persist-credentials: false: Credentials are never written to the local Git configuration [1][6].

Return CORS headers for token rejection responses.

A token expires after one hour. For an approved embedded origin, this response has no CORS headers. The browser then exposes a network failure instead of the 401 response, so the embed cannot reliably refresh its render session.

Authorize the request origin before returning this error, then attach CORS headers only when that origin is approved.

A blank required number is coerced to 0.

z.coerce.number() applies Number(value). Number("") returns 0. A required number or slider field that receives "" therefore passes validation and stores 0.

Remove the honeypot name to avoid a collision with a real field key.

The honeypot input uses name = "website" inside the same form. A lead form field keyed website is common. When both exist, form.elements["website"] at line 186 returns a RadioNodeList instead of the single input. Reading .value on that list returns the value of a checked radio, which is "" for text inputs, so valuesFrom drops the user's real value. The server then rejects the submission for a missing or invalid website field, and the user cannot submit.

Line 283 already reads the honeypot through the honeypotInput reference, so the name attribute is not needed for the request payload.

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.

Reject allowed values that need normalization.

Line 129 accepts " premium " because it only checks the trimmed value. formDefinitionV1Schema trims option values during form creation. Publishing then replaces the endpoint schema with "premium".

An existing endpoint can therefore accept a value before form attachment and reject the same value after publication. Require each allowed value to equal its trimmed form before marking the endpoint compatible.

🌐 Web query:

Resend API idempotency key reused with different payload 409 invalid_idempotent_request retention 24 hours

💡 Result:

The Resend API uses idempotency keys to ensure that specific email requests are processed only once, even if multiple identical requests are received [1][2]. When an Idempotency-Key is provided, Resend stores it along with the request payload and the response for 24 hours [1][2][3]. If you receive a 409 invalid_idempotent_request error, it indicates that you have reused an idempotency key within the 24-hour retention window, but the payload of the current request does not match the payload of the initial request [1][4][3]. Key points regarding this error: - Meaning: Resend has detected a mismatch between the current request body and the one previously associated with that specific key [1][2]. - Action: Retrying this request with the same key and the same (or different) payload will continue to result in this error [1][3]. You must either use a new, unique idempotency key for this different payload or wait for the 24-hour retention window to expire [1][4][5]. - Best Practices: Ensure that your idempotency keys are unique to each distinct email or batch you intend to send [2][6]. Do not use generic, reusable strings (e.g., 'welcome-email') as keys, as this will cause subsequent requests to fail with a 409 error once the first request is processed [2]. Do not implement automated retries for 409 invalid_idempotent_request errors, as they are not transient and require code-level changes to the key or payload to resolve [5].

Use a stable count in the email payload.

claimed.used reads the mutable usagePeriods.leadCount, while usageNotificationIdempotencyKey(input) stays stable for the threshold. If another lead is accepted before a retry, Resend can return 409 invalid_idempotent_request for the reused key within 24 hours. The catch path clears the claim, so pending retries can continue to fail.

Persist the threshold count when stamping notificationLimit80 or notificationLimit100, and use that snapshot for used.

Prevent duplicate submission keys during editing.

Line 584 normalizes the new key but does not check sibling fields. A user can assign the same key to two fields. The definition then fails duplicate-key validation and cannot publish. Reject the collision or allocate a unique suffix before updating the field.

Set the site token before rendering the frontend markup.

$combined is rendered before line 28 writes router_forms_site_token. The assertion at line 29 therefore checks markup generated with no token configured. A frontend token-leak regression can pass this smoke test. Move update_option before do_shortcode and render_block.

Reject the lead that reaches the paused threshold.

getCapacityState marks used >= graceLimit as paused. This strict comparison accepts the lead that increments usage to graceLimit. For a 100-lead limit, the request from 109 to 110 succeeds but returns paused capacity. Use >= so the transaction rolls back that submission.

Proposed fix
-    if (graceLimit !== null && usage.leadCount > graceLimit) {
+    if (graceLimit !== null && usage.leadCount >= graceLimit) {
