-- Form A (`262946078314059`) is implemented only in a non-indexing, seven-route `isolated-test` adapter: `/contact`, `/es/contact`, the four campaign landing routes and `/lp/early-intervention`. The five landing journeys use fixed `formContext=landing&language=en`, superseding only their earlier Form B mapping. Form B remains for the other service-consultation journeys; Form C remains professional referrals.
+- Form A (`262946078314059`) is implemented only in a non-indexing, seven-route `isolated-test` adapter: `/contact`, `/es/contact`, the four campaign landing routes and `/lp/early-intervention`. The five landing journeys use fixed `formContext=landing&language=en`. The owner has retired physical Form B: future family service journeys are planned for an unconfigured Form A `consultation` context, while Form C remains a separate future professional-referral form. The seven-route Form A allowlist is frozen until Builder configuration, synthetic acceptance and a separately authorized route change are complete. See [the two-form integration specification](phase-9-two-form-integration-specification-2026-10-28.md).
 - Owner-confirmed direct-Jotform evidence covers synthetic EN/ES submission, native thank-you, conditional email/language, generic no-answer/no-PDF staff notification, autoresponder delivery, corrected fixed Reply-To, no webhooks/integrations, privacy scope, recipient access and retention. The owner also reports successful Astro-iframe synthetic submission and confirmation on English contact, Spanish contact and one ABA landing placement; record the exact third route before release. Functional submission acceptance is complete only for those owner-reported samples. All-seven-route accessibility, runtime-network/telemetry, deployment and site-release acceptance remain open.
 - The adapter retains fixed URLs, responsive fixed heights, `no-referrer`, `allow-forms allow-scripts allow-same-origin`, no helper script, and a hosted fallback that is hidden without space until a 15-second missing-load timeout. A frame load only clears that timeout; it does not prove cross-origin application health or accepted submission. The official Jotform resizing handler is conditionally acceptable pending separately authorized source, origin, privilege, Firefox and error-state verification; it is not implemented. Fixed heights remain current.
-- A separate local production gate is prepared for Form A only. It requires `PUBLIC_AIA_FORMS_MODE=live`, `PUBLIC_AIA_FORMS_LIVE_APPROVED=true`, `PUBLIC_AIA_FORMS_ENVIRONMENT=production` and `PUBLIC_AIA_FORM_A_PRODUCTION_APPROVED=true`; the fixed seven-route allowlist remains enforced. `PUBLIC_ALLOW_INDEXING=true` permits an indexing-enabled release artifact but never authorizes a form. Normal/off/mock/isolated behavior remains fail-closed, and Forms B/C, service drawers, analytics and API forwarding remain inactive. Marketing-only notification routing is a pre-cutover operational check. Rolling back Form A means rebuilding with mode `off` or an absent approval value and switching only the static artifact; it does not alter Jotform.

 The indexing-enabled build has 127 HTML routes/canonicals and 109 sitemap URLs.
 Normal staging has 128 `noindex,nofollow` pages because it also contains `/lp`;
