# Phase 14 Implementation Report

## 1. Executive summary

Phase 14 converts the Phase 13 homepage demo calls to action into one controlled, localized dialog workflow backed by strict client and server validation, a POST-only API boundary, typed adapters, bounded timeout and idempotency handling, explicit destination and feature-flag registries, privacy-safe event contracts, deterministic test adapters, and release gates.

No production CRM, scheduler, email, consent, analytics, legal, login, tour, pricing, or support destination was invented. The safe local adapter discards submissions and is unavailable in ordinary production configuration. Production remains blocked by P14-001 through P14-009. Static validation, format, lint, strict type checking, 39 unit tests, 4 integration tests, coverage thresholds, dependency audit, secret scan, production build, standalone HTTP serving, API fail-closed behavior, and package validation pass in the available Node 22.16.0/npm fallback environment. Browser, axe, visual, and manual acceptance remain blocked by the host browser policy and human-review requirements.

## 2. Authoritative inputs reviewed

Phase 13 repository artifacts, handoff, implementation report, decision log, issue register, package manifest, homepage action/destination/event inventories, content and evidence rules, responsive/RTL/theme/accessibility/performance reports, CI documentation, and the earlier Phase 9 through Phase 12 contracts were reviewed. The Phase 9 demo form contract remains immutable.

## 3. Phase 13 baseline validation

The baseline installed from the provided archive. Existing static validators, formatting, linting, type checking, unit coverage, and production build were preserved. Phase 13 browser constraints remained reproducible: Chromium launches but loopback page navigation is rejected with `net::ERR_BLOCKED_BY_ADMINISTRATOR`.

## 4. Integration architecture

The implemented path is `homepage trigger → shared localized dialog → client schema → POST /api/demo → server schema and request controls → idempotency coordinator → typed destination adapter → normalized result → localized status → consent-gated allowlisted event`. Details are in `docs/phase14/INTEGRATION_ARCHITECTURE_v1.0.md`.

## 5. Destination registry

`src/lib/integrations/destinations.ts` centralizes status, kind, locale, issue, and feature-flag metadata. Only the internal demo dialog can become locally active. Unknown external destinations remain blocked or placeholders and never degrade to guessed links.

## 6. Demo workflow

Header, mobile header, hero, final CTA, and footer triggers open one native dialog host. Locale, direction, theme inheritance, focus containment/return, Escape behavior, and source attribution are preserved. The dialog uses no third-party embed and supports delayed hydration by leaving unavailable actions non-navigable before activation.

## 7. Form contract

The exact Phase 9 fields are implemented: full name, work email, company, approved fleet-size enum, optional market, preferred language, optional message, idempotency key, and approved source. No phone, consent, marketing, lead-score, or speculative enrichment field was added. See `docs/phase14/DEMO_FORM_CONTRACT_v1.0.md`.

## 8. Client validation

Zod-based validation trims and bounds content, applies practical email validation, rejects invalid enums, preserves correctable input, renders field and summary errors, avoids placeholder-only labels, and uses localized complete messages. Controls use native labels and autocomplete semantics where appropriate.

## 9. Server validation

The API repeats authoritative strict validation, rejects unknown fields, normalizes whitespace and email case, bounds all values, validates source and locale fields, rejects malformed JSON and oversized requests, and never trusts client-required state.

## 10. Submission API

`POST /api/demo` requires JSON, the approved request marker, a same-origin request in production, and a body no larger than 16 KiB. Unsupported methods return 405. Responses are normalized and no-store, include privacy-safe correlation identifiers on failure, and expose neither stack traces nor vendor bodies.

## 11. CRM or lead-destination integration

No vendor is approved. A typed `LeadDestinationAdapter` boundary and blocked production adapter are present. The development adapter discards data and returns an explicit local-only result. P14-001 blocks production activation.

## 12. Scheduling integration

No scheduler is approved or implemented. The adapter inventory and release gate preserve P14-006. No availability, booking confirmation, URL, locale support, or accessibility claim is fabricated.

## 13. Email integration

No email provider, template, sender, recipient, or delivery behavior is approved. No email is sent or claimed. P14-007 remains blocked.

## 14. Consent implementation

Distinct privacy acknowledgment, marketing opt-in, analytics consent, and necessary processing are documented in the consent matrix. Because approved legal text and basis are absent, no speculative checkbox is added and optional analytics remains disabled. P14-002 and P14-003 block activation.

## 15. Analytics integration

The provider-neutral client accepts only registered non-personal events after an explicit runtime consent marker. Its production mode is disabled; its test mode writes bounded metadata only to an in-memory window sink. It uses no cookies, browser storage, network request, user ID, or form value.

## 16. Analytics event contract

Approved event names and allowed properties are defined in `src/lib/analytics/events.ts` and `docs/phase14/ANALYTICS_EVENT_REGISTRY_v1.0.csv`. Runtime validation rejects unknown names, properties, and values. Success is emitted only after adapter acceptance.

## 17. Campaign attribution

No campaign persistence or forwarding was approved. The workflow does not store arbitrary query parameters, forward them to adapters, or include them in analytics. Campaign support remains excluded until a bounded policy is supplied.

## 18. Duplicate and idempotency handling

The client disables repeat submission while pending. The server coalesces matching in-flight and recently completed requests by UUID idempotency key for a bounded TTL. Only the key and normalized result are retained. A distributed store and business duplicate policy remain blocked by P14-004.

## 19. Abuse controls

The API enforces request marker, origin policy, content type, request size, strict fields, and a honeypot. It avoids inaccessible CAPTCHA and fingerprinting. Rate limits and distributed abuse policy require approved infrastructure and privacy review before production.

## 20. Success experience

Confirmed local-adapter acceptance produces an accessible localized status and clearly states that no real lead was sent. The flow does not claim an email or meeting. It keeps personal data out of the URL and prevents an immediate duplicate request.

## 21. Failure and degraded states

Localized validation, configuration, duplicate, timeout, integration, abuse, and unexpected-failure mappings are implemented. Retryability is explicit, input remains available after correctable failure, retries are bounded, and technical/vendor details are suppressed.

## 22. Environment management

Environment variables are parsed centrally, documented in `.env.example`, and inventoried. Server-only values stay server-side. Production demo activation rejects local mode unless the explicit loopback-only test escape is set. Missing approval fails closed.

## 23. Feature flags

Typed safe-default flags cover demo, CRM, scheduler, analytics, marketing consent, tour, pricing, and login states. Disabled destinations render intentional unavailable behavior. Flags do not substitute for decisions.

## 24. Security review

Origin checks, request markers, strict schemas, size limits, content-type checks, timeout, idempotency, non-reflected errors, no raw logging, existing CSP, and secret separation are implemented. Distributed rate limiting, durable replay controls, vendor scopes, webhook verification, and production CORS depend on the selected architecture. See the security report.

## 25. Privacy review

The data-flow inventory documents every field, purpose, processing point, recipient, storage behavior, consent status, and open owner. No form body is logged; no field enters analytics, URLs, snapshots, or browser persistence; the local adapter discards input. Retention, deletion, legal basis, recipients, and transfer rules remain blocked.

## 26. Accessibility validation

The form uses native controls, programmatic labels, descriptions, error summary, live status, keyboard dialog behavior, focus return, visible focus, non-color errors, paste-friendly inputs, and no time-limited interaction. Authored axe tests exist for EN/FR/AR, but observed browser execution is blocked and manual AT review remains open.

## 27. Localization validation

Complete form, validation, status, retry, and local-only messages exist in English, French, and formal Modern Standard Arabic. Translation parity validators pass. Native linguistic approval remains inherited from earlier open issues.

## 28. RTL validation

Arabic remains document-level RTL. Logical CSS, separate mixed-direction email values, logical icon placement, dialog reading order, and no physical left/right integration styling are enforced statically. Browser and screen-reader observation remains blocked.

## 29. Theme validation

The dialog consumes semantic tokens and inherits light, dark, and system behavior. No integration-specific raw palette is introduced. Authored light/dark visual cases remain unexecuted because browser loopback is blocked.

## 30. Responsive validation

The form uses content-driven sizing, a bounded viewport dialog, logical spacing, compact action stacking, and overflow control. Mobile browser scenarios are authored; 200/400-percent zoom and touch review require unblocked manual QA.

## 31. Unit-test results

Thirteen files and 39 tests pass. Coverage is 92.4% statements, 86.04% branches, 95.45% functions, and 92.64% lines for the configured source set.

## 32. Integration-test results

One integration file and four service tests pass, covering success, normalized adapter failure, timeout, and idempotent coalescing.

## 33. End-to-end test results

Five new Chromium workflow scenarios plus the inherited browser suite are authored. Execution reaches the browser but all local navigation is blocked by the host with `net::ERR_BLOCKED_BY_ADMINISTRATOR`; these are environment-blocked, not application failures or passes.

## 34. Security-test results

Static security validation passes for origin, content type, size, timeout, idempotency, and no-raw-log controls. High-confidence secret-pattern scanning passes. The production API smoke test rejects a structurally valid lead with HTTP 503 and `lead_destination_not_approved`.

## 35. Privacy-test results

Static privacy validation and unit tests pass for no browser persistence, URL leakage, unconsented analytics, event allowlists, and sensitive-key redaction. Browser privacy observation remains blocked by the host policy.

## 36. Visual-regression results

Five Phase 14 EN/FR/AR light/dark visual scenarios are authored. No baseline is approved because Chromium cannot navigate to the loopback server in this environment. Failure screenshots show the administrative block page and are not product baselines.

## 37. Manual QA results

The manual matrix is present but remains `Not run` for keyboard, pointer, touch, screen reader, zoom, reduced motion, forced colors, locales, themes, viewports, network transitions, and failure simulations. Human observations are not fabricated.

## 38. Observability

Failures use generated correlation IDs containing no personal data. Result categories are bounded. No provider, remote log sink, alert, or retention schedule is activated. P14-005 requires operational approval.

## 39. Performance and bundle impact

No runtime dependency or vendor SDK was added. The standalone tree is approximately 36.4 MB and static assets approximately 1.52 MB in the available build. Optional integrations contribute zero bytes. Lighthouse and interaction timing remain blocked by browser policy. See the performance report and bundle inventory log.

## 40. Dependency changes

No dependency was added. `npm audit --offline --audit-level=low` reports zero vulnerabilities against the available lock/cache. Authoritative frozen pnpm installation on Node 24.17.0 remains required.

## 41. Deviations from approved specifications

A dedicated route was not invented; the existing approved dialog pattern was used. CRM, scheduling, email, consent text, analytics provider, attribution persistence, and distributed rate limiting are represented by blocked boundaries rather than fake integrations. The local adapter is a safe development implementation, not production completion.

## 42. Open issues and release blockers

P14-001 through P14-009 cover vendor selection, legal processing, analytics consent, distributed idempotency, observability, scheduler, email, browser/manual validation, and pinned environment verification. Inherited P9 through P13 issues remain authoritative.

## 43. Files added, changed, and removed

Source, test, documentation, validation, and configuration additions are listed in `docs/quality/PHASE_14_FILE_CHANGES_v1.0.txt`. No authoritative contract file was removed or rewritten.

## 44. Commands required to install, validate, test, build, and run

Use Node 24.17.0 and pnpm 11.9.0 in release CI. Commands are documented in README, the Phase 15 handoff, and `docs/quality/PHASE_14_COMMAND_LOG_v1.0.txt`. The available host used an explicitly recorded npm offline fallback.

## 45. Production configuration requirements

Production requires approved `SITE_ORIGIN`, enabled public demo flag, non-local submission mode, typed vendor credentials and mappings, legal/consent approval, retention/deletion policy, distributed idempotency/rate limits, monitoring, and resolved legal/alternative destinations. Test-scenario and local-test flags must be false.

## 46. Rollback considerations

Disable `NEXT_PUBLIC_DEMO_ENABLED` to revert all demo triggers to unavailable behavior without removing the homepage. Do not roll back schema, redaction, or destination controls while leaving submission active. Vendor adapters must support independent disablement and fail closed.

## 47. Phase 15 readiness assessment

Phase 15 can execute final automated QA and resilience validation without restructuring the integration boundary. It cannot declare production readiness until P14 blockers and inherited acceptance gates are resolved. The repository is structurally ready for vendor adapters once authoritative decisions arrive.
