# PO Master Checklist Validation Report
Project: United Tattoo
Checklist: .bmad-core/checklists/po-master-checklist.md
Mode: Comprehensive (YOLO)
Date: 2025-09-18 17:31 MT
Reviewed Artifacts (evidence):
- PRD Index: docs/prd/index.md
- Epics: docs/prd/epics.md
- Brownfield Rollback Strategy: docs/prd/rollback-strategy.md
- Package manifest/scripts: package.json
- Repository structure (Next.js App Router, app/, components/, sql/schema.sql, wrangler.toml present)

Project Type Determination:
- Type: Brownfield
- UI/UX: Yes (public-facing site + admin + booking)
- Sections skipped due to type: All [GREENFIELD ONLY] items
---
## Executive Summary

## 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
- 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]

- 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

### 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: 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
