# Dependency graph
requires:
  - phase: none
    provides: first plan, no prior dependencies
provides:
  - CLAUDE.md behavioral instructions for Claude across all workflows
  - STRUCTURE.md folder hierarchy map for the entire project
affects: [01-02, 01-03, 02-01, 04-01, all future plans reference CLAUDE.md]

# Tech tracking
tech-stack:
  added: [none - pure markdown]
  patterns: [reference-authority, progressive-disclosure, french-first]

key-files:
  created:
    - CLAUDE.md
    - STRUCTURE.md
  modified: []

key-decisions:
  - "CLAUDE.md at 92 lines - well under 200 line limit, leaving room for future additions"
  - "All prohibitions include rationale explaining why the rule exists"
  - "Progressive disclosure: CLAUDE.md points to reference/ files, never duplicates their content"

patterns-established:
  - "Reference authority: reference/ files override Claude's training data"
  - "French-first: all project files and interactions default to French"
  - "Kebab-case naming: artists/[nom-en-kebab-case]/ convention"

# Phase 1 Plan 1: CLAUDE.md and STRUCTURE.md Summary

**CLAUDE.md (92 lines, 9 sections, French) defining all behavioral rules with progressive disclosure to reference/ files, plus STRUCTURE.md mapping the full project hierarchy**

## Performance

- **Duration:** 2 min
- **Started:** 2026-04-10T10:26:03Z
- **Completed:** 2026-04-10T10:27:51Z
- **Tasks:** 2
- **Files modified:** 2

## Accomplishments
- CLAUDE.md created with all 9 required sections covering language, principles, workflows, production format, naming conventions, verification, prohibitions, and update policy
- Every prohibition includes its rationale (e.g., "Suno derive entre les accents aux frontieres de section")
- STRUCTURE.md accurately maps all directories and files: reference/, artists/, base/, suno/, linguistic/, templates/
- Both files entirely in French with no English prose

## Task Commits

Each task was committed atomically:

1. **Task 1: Create CLAUDE.md with all behavioral rules** - `dae140d` (feat)
2. **Task 2: Create STRUCTURE.md mapping the full project hierarchy** - `915031e` (feat)

## Files Created/Modified
- `CLAUDE.md` - Behavioral instructions for Claude: 9 sections, 92 lines, all locked decisions implemented
- `STRUCTURE.md` - Complete folder hierarchy map with French descriptions for every entry

## Decisions Made
- Kept CLAUDE.md at 92 lines (well under 200 limit) to leave room for future additions without approaching the limit
- All 10 prohibitions include rationale explaining the "why" behind each rule
- Used progressive disclosure consistently: 4 references to `reference/suno/format.md` and 2 to `reference/linguistic/` without duplicating any content

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered
None

## User Setup Required
None - no external service configuration required.

## Next Phase Readiness
- CLAUDE.md and STRUCTURE.md are in place for all subsequent plans
- Plan 01-02 (reference file structure and Suno specs) can proceed immediately
- Plan 01-03 (linguistic rule stubs) can proceed after 01-02

## Self-Check: PASSED

- FOUND: CLAUDE.md
- FOUND: STRUCTURE.md
- FOUND: 01-01-SUMMARY.md
- FOUND: commit dae140d (Task 1)
- FOUND: commit 915031e (Task 2)
