# Phase 13 Implementation Report

## 1. Executive summary

Phase 13 replaces the Phase 11 foundation placeholder at `/{locale}` with the complete RentalDriveGo marketing homepage assembled from the Phase 12 component system. The route now renders the approved narrative in English, French, and Arabic: hero, operational coverage, fragmented-versus-connected comparison, reservation-to-return workflow, operating roles, product modules, measurement framework, integrations, security evaluation, pricing preview, FAQ, and final CTA.

The implementation preserves document-level Arabic RTL, light/dark/system themes, semantic tokens, logical CSS, route helpers, evidence controls, and unavailable-destination behavior. It does not invent customer proof, quantified outcomes, certifications, public prices, partner names, product captures, CRM behavior, analytics, legal consent, login, tour, sales, or demo destinations.

Static validation, formatting, lint, strict type checking, 27 unit tests, coverage thresholds, production build, standalone preparation, and direct HTTP locale checks pass in the available environment. Formal acceptance remains blocked by browser policy, manual accessibility review, native linguistic approval, exact Node 24.17.0 execution, frozen pnpm completion, audit completion, and inherited product approvals.

## 2. Authoritative inputs

- `docs/PHASE_13_HANDOFF_v1.0.md`.
- `docs/PHASE_12_IMPLEMENTATION_REPORT_v1.0.md`.
- Phase 12 component inventory, catalog, accessibility, RTL, responsive, traceability, and issue records.
- Existing EN, FR, and AR homepage catalogs.
- Immutable Phase 9 contracts and Phase 11 token, theme, localization, route, metadata, security, and shell foundations.

## 3. Homepage composition

The route sequence is documented in `docs/phase13/HOMEPAGE_SECTION_MATRIX_v1.0.csv`. Header and footer hashes now resolve to real sections for `product`, `workflow`, `modules`, `pricing`, and `faq`.

The implementation uses existing `ActionLink`, `Accordion`, `CTA`, `Comparison`, `FeatureCard`, `FeatureGrid`, `ProductPreview`, `SectionHeader`, `Workflow`, `Callout`, `Card`, typography, icon, container, section, and stack primitives. No duplicate public component family was introduced.

## 4. Typed content model

`src/content/homepage-model.ts` creates one typed `HomepageContent` object per locale. It converts localized pair and triple arrays into stable IDs and semantic records, fails closed on malformed content, supplies approved icon semantics, isolates product-preview identifiers, and requires unavailable reasons for unresolved actions.

The route owns order and composition. Components remain locale-independent and content-independent. Details are in `docs/phase13/HOMEPAGE_CONTENT_MODEL_v1.0.md`.

## 5. Hero and product preview

The hero uses the approved conversion hierarchy while both actions remain disabled because destinations are unresolved. The product view is a deterministic illustrative `ProductPreview` built from fictional localized fixture content. The caption explicitly states that final screens require approved product data and captures.

`ProductPreview` received one backward-compatible `headingLevel` prop. The default remains level 3; the hero uses level 2 to avoid a semantic jump from the page heading to a level-3 preview heading. The change is recorded in `docs/phase13/COMPONENT_VARIANT_UPDATE_v1.0.md`.

## 6. Evidence, claims, pricing, and destinations

- Operational coverage and capability descriptions are presented without customer proof.
- The results section publishes KPI definitions and measurement methodology, not invented values.
- Named integration partners are suppressed.
- Security certifications and service-level claims are suppressed.
- Public prices, discounts, packages, and limits are suppressed.
- Demo, tour, pricing, and sales actions are non-navigable and include localized unavailable reasons.
- No `href="#"`, guessed URL, root fallback navigation, CRM request, fake success state, or analytics adapter was added.

## 7. Localization and RTL

All visible route copy is read from the existing locale catalogs. English and French render LTR; Arabic renders with true document-level RTL. Page CSS uses logical declarations. Directional workflow icons use the existing mirroring contract, while product media and branding remain fixed. Vehicle identifiers remain separate left-to-right `BidiText` values.

Native French and Arabic review remains required under P9-005 and P11-004.

## 8. Responsive, theme, and accessibility implementation

The route uses content-driven grids and switches two-column hero, integration, and pricing layouts to a single column below 768 CSS pixels. Actions become full width on compact mobile. Decorative hero transforms are removed in forced-colors and reduced-motion contexts. The implementation contains one page-level `h1`, coherent subsequent heading levels, native FAQ disclosures, visible focus inherited from the foundation, disabled-action reasons, and no page-local raw palette values.

Authored tests cover 1440, 1024, 768, 390, and 320 widths through the existing responsive suite plus Phase 13 homepage scenarios. Browser execution remains blocked locally, so these scenarios are not presented as observed passes.

## 9. Test additions

- `tests/unit/homepage-content.test.ts`: five content-model and destination-policy tests.
- `tests/browser/homepage.spec.ts`: nine locale, section, disabled-action, bidi, anchor, and FAQ scenarios.
- `tests/a11y/homepage.a11y.spec.ts`: three locale axe scenarios plus heading-outline validation.
- `tests/visual/homepage.visual.spec.ts`: seven EN/FR/AR light/dark desktop/tablet/mobile/320 baselines.

## 10. Validation results

Passed:

- Static repository validation through Phase 13.
- Prettier formatting check.
- ESLint with zero warnings.
- Strict TypeScript validation.
- 27 unit tests across 9 files.
- Coverage thresholds: 92.4 percent statements, 86.04 percent branches, 95.45 percent functions, and 92.64 percent lines.
- Next.js production build and standalone preparation.
- Direct HTTP 200 checks for EN, FR, and AR with correct `lang`, `dir`, and localized hero payloads.
- Phase 13 package manifest generation and verification.

Blocked or open:

- Frozen pnpm installation after registry `EAI_AGAIN` failures.
- Dependency audit because registry connectivity did not permit completion.
- Exact Node 24.17.0 verification because the available host is Node 22.16.0.
- Browser, axe, and visual execution because system Chromium rejects loopback navigation with `net::ERR_BLOCKED_BY_ADMINISTRATOR`.
- Manual keyboard, touch, screen-reader, zoom/reflow, reduced-motion, forced-colors, theme, RTL, and visual review.

Detailed evidence is in `docs/quality/PHASE_13_VALIDATION_RESULTS_v1.0.{md,json}`, the HTTP result JSON, command log, manual matrix, and file-change list.

## 11. Files changed

The source delta adds the homepage content model, Phase 13 tests, validators, manifest scripts, decision and issue records, composition documentation, and quality evidence. It modifies the homepage route and stylesheet, package scripts and metadata, validation runner, and `ProductPreview` heading semantics. No file was deleted. The exact list is recorded in `docs/quality/PHASE_13_FILE_CHANGES_v1.0.txt`.

## 12. Open gates

Inherited P9, P10, P11, and P12 gates remain authoritative. Phase 13 adds:

- P13-001: browser, axe, and visual execution in unblocked CI.
- P13-002: manual responsive and assistive-technology QA.
- P13-003: exact target runtime, frozen installation, audit, and package verification in the pinned environment.

See `docs/IMPLEMENTATION_ISSUE_REGISTER_v1.3.csv`.

## 13. Phase 14 readiness

Phase 14 may proceed with approved integration or production-readiness work using this homepage as the assembled route baseline. It must not reinterpret disabled destinations, illustrative media, open evidence, unapproved pricing, or unresolved legal and analytics controls as completed merely because the page now looks like a product rather than a scaffolding accident.
