Route Architecture Specification — Learning Outcomes
Context
An architecture audit of the cho-co/web Next.js 15 App Router identified 9 issues across Critical/High/Medium severity: duplicate layouts, missing error boundaries, redirect conflicts, and fragile dark mode CSS. Rather than amending SRS-004 (product-level IA), a new SRS-010 was created for the technical route architecture concern — different domain, different verification methods.Learning Outcomes
1. Audit-to-SRS Pipeline
The audit findings mapped cleanly into formal requirements:| Audit Code | Severity | SRS Requirement | Priority |
|---|---|---|---|
| C1 | Critical | REQ-010-001 (Route Groups) + REQ-010-002 (Shared Layout) | CRITICAL |
| C2 | High | REQ-010-003 (Redirect Conflict) | HIGH |
| C3 | High | REQ-010-004 (Middleware Routes) | HIGH |
| H1 | Critical | REQ-010-005 (Error Boundaries) | CRITICAL |
| H2 | High | REQ-010-006 (Loading States) | HIGH |
| H3 | Medium | REQ-010-007 (Padding Consolidation) | MEDIUM |
| M1 | High | REQ-010-008 (Dark Mode) | HIGH |
| M2/M3 | Medium | REQ-010-009 (Static Rendering) | MEDIUM |
2. SRS Separation of Concerns
SRS-004 governs what the rooms are called and where they live (Information Architecture). SRS-010 governs how the rooms are built and wired (Route Architecture). The two share cross-references (REQ-010-001 → REQ-004-001) but have independent verification methods:- SRS-004: DEMO, REVIEW (user-facing)
- SRS-010: INSPECT, TEST (code-facing)
3. BUNDLE Implementation Blueprint Pattern
BUNDLE-E follows the BUNDLE-A pattern:- YAML header with prerequisite, gaps addressed, priority range, duration, risk
- Tasksets with sequential IDs (E1, E2)
- Each taskset has: file change tables, code patterns, verification checklists
- Full AC traceability table at the end
4. Cross-Repository Documentation Strategy
Specifications live in choco-hq (the governance repo), while implementation will happen in cho-co/web (the product repo). This separation means:- Specs can be reviewed and baselined independently of code
- Multiple implementation attempts don’t pollute the spec history
- Cross-references work bidirectionally via requirement IDs
5. Agentic Operations Patterns
This specification was produced through a 5-agent parallel exploration followed by sequential document authoring:- 5 repos explored concurrently (choco-hq, atlas, so1-content, veritas, ariel)
- Pattern extraction from existing SRS-009 and BUNDLE-A
- Sequential creation: SRS-010 → BUNDLE-E → Master Index update → cross-repo docs
- Cross-repo distribution to 4 repositories for baseline, learning, findings, and reference
6. Marketing Campaign Potential
The route architecture consolidation enables several marketing narratives:| Campaign Theme | Angle | Channel |
|---|---|---|
| ”The Factory Floor Plan” | Technical credibility — showing architectural discipline | Blog post |
| ”Zero to Boundaries” | Error handling maturity story | Twitter/X thread |
| ”One Layout to Rule Them” | DX improvement through consolidation | DevRel content |
| ”Dark Mode Done Right” | CSS custom properties best practice | Tutorial |
Files Produced
