Project Setup & Initialization Status: PASS (85%) - 1.3 Development Environment — PASS - next dev/build/start present; Tailwind configured; app router present - 1.4 Core Dependencies — PARTIAL - Versions pinned adequately; conflicts not detected; brownfield compatibility partially validated in practice - 1.2 Existing System Integration [BROWNFIELD] — PARTIAL - Local testing approach exists (vitest), but explicit regression guardrails/process not fully documented for brownfield deltas Actions: - Add a “Local Dev Setup” section to README with explicit tool versions and smoke checklist - Document brownfield regression plan at story or epic level (link to tests approach) ### 2. Infrastructure & Deployment Status: PARTIAL (70%) - 2.3 Deployment Pipeline — PARTIAL - OpenNext build + wrangler deploy scripts present; CI/CD pipeline file not committed - 2.1 Database & Data Store Setup — PARTIAL - D1 used with sql/schema.sql; no migrations directory or down scripts implemented - 2.4 Testing Infrastructure — PASS/PARTIAL - Vitest + RTL configured; component/E2E (Playwright) not present in repo Actions: - Commit CI pipeline (lint, typecheck, test, build, preview deploy); enforce budgets - Introduce sql/migrations/{timestamp}_up.sql and corresponding _down.sql; add npm scripts - Add Playwright for E2E critical flows (admin auth, booking form happy-path, public pages) ### 3. External Dependencies & Integrations Status: PARTIAL (75%) - Third-party services/API keys — PARTIAL - Env validation via lib/env.ts exists; secrets via wrangler; explicit storage/rotation guidance not fully documented - External APIs — N/A or PASS (current scope primarily internal) Actions: - Expand env/secret handling doc: wrangler secrets put process + required vars matrix for preview/prod ### 4. UI/UX Considerations [UI/UX ONLY] Status: PARTIAL (70%) - Design system setup — PASS/PARTIAL - Tailwind, shadcn/ui patterns present; accessibility policy not fully documented - Frontend infra — PASS - App Router, build pipeline OK - UX flow/error/loading patterns — PARTIAL - Core flows present; global a11y/error/loading standards doc not found Actions: - Add a11y acceptance checklist; standardize error/loading skeletons; document form validation patterns (Zod + RHF) app-wide ### 5. User/Agent Responsibility Status: PARTIAL (60%) - Responsibilities delineation — PARTIAL - BMAD personas exist; explicit “who does what” for external accounts/payment credentials not clearly captured in PRD Actions: - Add a PRD “Responsibilities” section (user vs agents), especially for accounts, payments, long-lived creds ### 6. Feature Sequencing & Dependencies Status: PASS (80%) - Functional/technical dependency sequencing — PASS - Epics articulate sequencing; stories exist for feature flags - Cross-epic dependencies — PARTIAL - Good linkage; ensure early infra tasks (flags/migrations/observability) precede feature toggling Actions: - Ensure flags and migration framework tasks are scheduled before dependent stories ### 7. Risk Management [BROWNFIELD ONLY] Status: STRONG PASS (90%) - Rollback strategy — PASS - docs/prd/rollback-strategy.md comprehensive; explicit flags, triggers, runbooks - DB/R2 rollback — PARTIAL - Plan documented; “down” migrations and backup scripts not yet implemented Actions: - Implement flags wiring; add db:backup script; create initial down migrations ### 8. MVP Scope Alignment Status: PASS (80%) - Core goals alignment — PASS - User journeys completeness — PARTIAL - Booking/admin/public happy-paths defined; edge/error states captured but require a11y/error docs - Technical requirements — PARTIAL - Performance/observability not yet wired Actions: - Add observability + performance budgets; define a11y minimums ### 9. Documentation & Handoff Status: PARTIAL (75%) - Dev docs (API/setup/decisions) — PARTIAL - Good architecture/PRD; API route docs limited; ADRs not formalized - User docs — PARTIAL - Public banners/communications outlined in rollback doc; UX specs can be expanded Actions: - Add lightweight ADRs for key decisions; document API route contracts (request/response, headers, caching) ### 10. Post-MVP Considerations Status: PARTIAL (70%) - Future enhancements separation — PASS - Monitoring & feedback — PARTIAL - Sentry/OTel not implemented; thresholds defined but not instrumented Actions: - Add Sentry + basic OTel; wire minimal metrics (route latencies, 5xx counts) --- ## Failed/Partial Items (Selected) with Context - Feature flags not yet wired in code (FAIL) - Evidence: Rollback doc Appendix A notes flags wiring “not yet implemented” - No down migrations or structured migrations dir (FAIL) - Evidence: Only sql/schema.sql found; no sql/migrations/ with up/down pairs - CI/CD pipeline not committed (FAIL) - Evidence: No workflows or CI config in repo; scripts exist but automation missing - Observability not implemented (PARTIAL/FAIL) - Evidence: No Sentry/OTel deps or init code present - a11y/error/loading standards not documented (PARTIAL) - Evidence: No explicit doc; components exist but standards undefined --- ## Brownfield-Specific Analysis - Integration risk level: Medium - Mitigations: Strong rollback plan, but lack of wired flags and down migrations increases operational risk - Existing system impact assessment: Good coverage via rollback doc; verify admin and booking critical paths with E2E - Rollback readiness: Conceptually strong; needs code + scripts to operationalize - User disruption potential: Medium; mitigated by feature flags once implemented --- ## Risk Assessment Top 5 Risks 1) Missing feature flag wiring delays safe rollout and reversibility (Impact: High, Prob: Med) 2) Lack of down migrations increases DB recovery time (High, Med) 3) No CI/CD pipeline risks regressions slipping to prod (High, Med) 4) Missing observability reduces detection speed for incidents (High, Med) 5) a11y/error/loading consistency gaps hurt UX and recovery UX (Med, Med) Mitigations - Implement flags + toggles first; build small demo wiring across admin/booking/public - Establish migration framework with initial up/down; add db:backup script - Commit CI with lint, typecheck, test, build, preview deploy; enforce budgets - Add Sentry + minimal OTel; instrument critical routes - Document a11y/error/loading patterns; add automated a11y checks Timeline impact: 2–4 dev days to reach green on critical items (flags+migrations+CI), 1–2 days for observability and UX standards --- ## MVP Completeness - Core features coverage: Solid foundation per Epics - Missing essentials: Flags wiring, down migrations, CI pipeline, observability - Scope creep: None apparent; strong alignment with business goals --- ## Implementation Readiness - Developer clarity score: 8/10 - Ambiguous requirements: Low; primarily operationalization gaps - Missing technical details: Migration down scripts, CI config, observability setup - Integration point clarity (brownfield): Good in rollback doc; needs E2E to lock confidence --- ## Recommendations Must-fix before development 1) Wire feature flags across admin, booking, public (server + client usage) 2) Introduce sql/migrations with up/down; add npm run db:backup and dry-run on preview 3) Commit CI pipeline (lint/type/test/build/preview deploy) with budgets Should-fix for quality 4) Add Sentry + minimum route metrics; alert thresholds matching rollback triggers 5) Add Playwright E2E for admin auth, booking submit, key public pages Consider for improvement 6) API route docs with request/response schemas; add ADRs 7) a11y/error/loading standards doc + automated a11y checks Post-MVP deferrals 8) Advanced analytics/feedback loops; KV-based instant flags --- ## Brownfield Integration Confidence - Preserve existing functionality: Medium → High after flags + E2E - Rollback procedure completeness: Conceptually High; implementation Medium (needs flags, downs, scripts) - Monitoring coverage for integration points: Low → Medium after Sentry/metrics - Support team readiness: Moderate; comms templates exist --- ## Category Statuses | Category | Status | Critical Issues | | --------------------------------------- | ---------- | --------------- | | 1.
