**Current focus:** Phase 1 - Core Infrastructure & Security

## Current Position

Phase: 1 of 9 (Core Infrastructure & Security)
Plan: 5 of 5 in current phase
Status: Phase complete
Last activity: 2026-01-25 - Completed 01-05-PLAN.md

Progress: [█████░░░░░] 11%

## Performance Metrics

**Velocity:**
- Total plans completed: 5
- Average duration: 4 min
- Total execution time: 20 min

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 01 | 5 | 20 min | 4 min |

**Recent Trend:**
- Last 5 plans: 01-01 (3 min), 01-02 (6 min), 01-03 (3 min), 01-04 (4 min), 01-05 (4 min)
- Trend: Stable

## Accumulated Context

### Decisions

Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:

- [Roadmap]: 9-phase structure following research recommendations - infrastructure first, then backend systems, then user features, then polish
- [01-01]: Used hatchling as build backend for pyproject.toml
- [01-01]: Created root /health endpoint outside versioned API for simple health checks
- [01-02]: Port 5433 for PostgreSQL (5432 in use by another container)
- [01-02]: Connection pool settings from research: pool_size=10, max_overflow=20, pool_recycle=1800
- [01-03]: Security headers applied via custom middleware (Starlette @app.middleware pattern)
- [01-03]: Health endpoints exempt from rate limiting via @limiter.exempt decorator
- [01-03]: CSRF validation available as optional dependency injection pattern
- [01-05]: SOURCE_DATE_EPOCH derived from config hash (not wall clock) for deterministic builds
- [01-05]: 20 minute hard timeout for sandbox builds (15 min warning)
- [01-05]: Resource limits: 8GB RAM, 4 cores for builds (speed over concurrency)

### Pending Todos

None yet.

### Blockers/Concerns

**Phase 1 complete:**
- systemd-nspawn sandbox implemented with network isolation
- Deterministic builds verified with SOURCE_DATE_EPOCH and fixed locales

**Phase 7 readiness:**
- 3D visualization requires 60fps target on Intel UHD Graphics - may need early performance prototyping

**Phase 8 readiness:**
- SAT solver integration complexity is high - research phase recommended before planning
