Detailed Findings

1. 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

  • 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:

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

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

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

    • 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:

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: 24 dev days to reach green on critical items (flags+migrations+CI), 12 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. Project Setup & Initialization PASS
2. Infrastructure & Deployment PARTIAL CI, migrations
