# Project State

## Project Summary

**Building:** Brownfield support for GSD - `/gsd:map-codebase` workflow that analyzes existing codebases using parallel Explore agents, producing structured `.planning/codebase/` documents.

**Core requirements:**
- `/gsd:map-codebase` produces useful codebase documents from any codebase
- Documents are focused (<100 lines each) and easy to update incrementally
- `/gsd:new-project` detects existing code and offers mapping
- `/gsd:plan-phase` loads relevant codebase context automatically
- Codebase map updates after plan execution

**Constraints:**
- Explore agents required for initial mapping
- Each codebase map file must stay under ~100 lines
- Only load relevant codebase sections into phase planning
- Follow existing GSD command/workflow/template patterns

## Current Position

Phase: 9 of 9 (Integrate Verify-Work)
Plan: 1 of ? in current phase
Status: In progress
Last activity: 2026-01-08 - Completed 09-01-PLAN.md

Progress: ████████████░ 93% (15 of 16+ plans)

## Performance Metrics

**Velocity:**
- Total plans completed: 15
- Average duration: 2.7 min
- Total execution time: 40 min

**By Phase:**

| Phase | Plans | Total | Avg/Plan |
|-------|-------|-------|----------|
| 1 | 3 | 9 min | 3 min |
| 2 | 2 | 5 min | 2.5 min |
| 3 | 1 | 2 min | 2 min |
| 4 | 2 | 7 min | 3.5 min |
| 5 | 2 | 5 min | 2.5 min |
| 6 | 2 | 4 min | 2 min |
| 7 | 1 | 4 min | 4 min |
| 8 | 1 | 1 min | 1 min |
| 9 | 1 | 3 min | 3 min |

**Recent Trend:**
- Last 5 plans: 06-01 (2m), 06-02 (2m), 07-01 (4m), 08-01 (1m), 09-01 (3m)
- Trend: Stable (2-4 min avg)

## Accumulated Context

### Decisions Made

| Phase | Decision | Rationale |
|-------|----------|-----------|
| 0 | Folder with focused files | Easier to update incrementally than monolithic file |
| 0 | Update after plan execution | Fits existing STATE.md update pattern |
| 0 | Parallel Explore agents | Thoroughness for initial mapping |
| 0 | Selective context loading | Avoid loading irrelevant sections |
| 6 | Frontmatter with dependency graph | Enable automatic context assembly via transitive closure |
| 6 | Intelligent summary selection | Scan frontmatter, build graph, auto-select relevant phases |
| 8 | Active milestone details in ROADMAP.md | Single source of truth during development, archive only on completion |
| 9 | Phase-scoped UAT issues | Keep UAT findings tied to specific plan, not global ISSUES.md |

### Deferred Issues

None yet.

### Blockers/Concerns Carried Forward

None yet.

### Roadmap Evolution

- Phase 4 added: Plan-phase optimizations (~37% context reduction target)
- Phase 5 added: TDD instructions for appropriate test-driven development
- Phase 6 added: Frontmatter and related system upgrade
- Phase 7 added: Backfill existing summaries with frontmatter
- Phase 8 added: Improve roadmap system
- Phase 9 added: Integrate verify-work (community contribution from OracleGreyBeard)
