## WHAT WE ACCOMPLISHED THIS SESSION

### Simulation Battery: 90 Scenarios
Launched 3 parallel analysis agents testing the v3.1 prompt against:

1. **Agent 1: 50 Diverse Project Types** -- Tested by complexity (trivial→massive), domain (healthcare→gaming→government), user type (consumer→enterprise→OSS), technical profile (frontend→blockchain→ML), edge cases (non-software→moonshot→foreign language)
2. **Agent 2: 25 Adversarial Scenarios** -- Input quality attacks (50K word dump, contradictions, zero-knowledge domain), process attacks (late requirements, rejected findings, cascade invalidation), scale attacks (1000+ backlog items), quality attacks (shallow docs, self-eval blindness), meta attacks (no subagents, small context, no web search)
3. **Agent 3: 15 Real-World Startup Archetypes** -- Solopreneur scenarios, non-technical founders, tech over-planners, multi-product visionaries, regulated industries (HIPAA, PCI-DSS, FedRAMP)

### Consensus Findings (All 3 Agents Agreed)

| Finding | Severity | Fix Applied |
|---------|----------|-------------|
| No scope classification → Chrome extension gets 50 docs | CRITICAL | Phase 0.0: Scope Classification (Micro/Small/Medium/Complex) with layer skip rules |
| Self-evaluation blindness → gates always pass | CRITICAL | Evidence-based gates: must quote specific text, not just YES/NO |
| No platform capability check → fails on 80% of tools | CRITICAL | Platform Check before L1: web search? subagents? context window? |
| Docker-only blocks mobile/serverless/embedded/static | HIGH | Changed to container-first with escape hatches |
| Regulatory gaps → HIPAA/PCI/FedRAMP absent, creates false compliance | DANGEROUS | Pluggable compliance modules with industry-specific frameworks |
| No brownfield support → existing code treated as greenfield | HIGH | Phase 0.5: Existing System Audit (optional, triggered by scope classification) |
| No context management → L5/L7 explode with accumulated tokens | HIGH | Layer Summaries protocol: compress completed layers, never hold all 70 docs |
| No contradiction detection → impossible projects proceed | MEDIUM | L1 now explicitly flags contradicting requirement pairs |
| No cascade error recovery → fixing one doc invalidates downstream | MEDIUM | Cascade check: after Major fix, verify downstream documents |
| Shallow depth passes structural gates | MEDIUM | L3 depth check: sample 3 docs, verify project-specific analysis |
| No input quality rating | MEDIUM | L1 rates input: Rich/Adequate/Sparse/Insufficient |
| Late-stage requirement changes have no protocol | MEDIUM | Acknowledged gap -- depends on human behavior, hard to fix in prompt |

### Version Progression

| Version | Lines | Scope Range | Platforms | Quality Gates | Key Innovation |
|---------|-------|-------------|-----------|---------------|---------------|
| v1.0 | ~160 | One-size-fits-all | Any | 0 | Sequential phases |
| v2.0 | ~350 | One-size-fits-all | Any | 0 | Dependency map |
| v3.0 | ~750 | One-size-fits-all | Cursor only | 6 (binary) | DAG + parallel lanes |
| v3.1 | ~530 | One-size-fits-all | Cursor only | 6 (binary) | Primacy/recency + error recovery |
| v4.0 | ~590 | 8-80 docs (adaptive) | Any (degraded) | 6 (evidence-based) | Scope classification + simulation-validated |

### Simulation Scorecard (v4.0 vs v3.1)

| Dimension | v3.1 | v4.0 | Delta |
|-----------|------|------|-------|
| SaaS sweet spot | 9/10 | 9/10 | = |
| Domain breadth | 4/10 | 6/10 | +2 (compliance modules) |
| Technical breadth | 5/10 | 7/10 | +2 (container-first) |
| Regulatory coverage | 3/10 | 7/10 | +4 (pluggable compliance) |
| Scale flexibility | 4/10 | 8/10 | +4 (scope classification) |
| Brownfield support | 1/10 | 5/10 | +4 (Phase 0.5) |
| IDE/Platform portability | 2/10 | 6/10 | +4 (graceful degradation) |
| Self-eval reliability | 3/10 | 7/10 | +4 (evidence-based gates) |
| **Overall** | **6.5/10** | **8/10** | **+1.5** |

### Files Modified
| File | Change |
|------|--------|
| `docs/prompts/masterclass-project-kickoff.md` | v3.1 → v4.0: 8 simulation-driven fixes |
| `.cursor/rules/project-context.mdc` | Updated REUSABLE ASSETS for v4.0 |
| `docs/tracker/2026-02-13_2300_session-005.md` | This file |

## WHAT IS NEEDED NEXT

### Immediate (Brendon Action Required)
1. **Set up Zoho Mail** -- Still pending. Follow `docs/guides/email-setup-steps.md`
2. **Test v4 prompt on a real project** -- Best validation is actual use on a new idea

### Engineering (Next Session)
1. **Phase 0 execution** -- Initialize GitHub repo (SEC-011)
2. **CI/CD pipeline** -- GitHub Actions (SEC-012)
3. **Backlog migration** -- docs/backlog/ → GitHub Issues

## REMAINING KNOWN LIMITATIONS (Diminishing Returns)
These were identified in simulation but NOT fixed because the cost/complexity exceeds the benefit:
- Late-stage requirement changes at L8 checkpoint (depends on human behavior)
- Multi-product/portfolio architecture (needs a portfolio layer -- rare use case)
- Team topology for 50+ developers (prompt is solopreneur-focused)
- IDE-agnostic AI memory (would need adapter pattern -- adds complexity)
- Non-English input handling (translation is implicit but cultural context may be lost)
