TASK: Extract knowledge-base facts for chunk <id> (<dirs>) of <repo-root>.
Steps, in order:
1. Inventory each directory in scope: file count, LOC, languages, entry files.
2. Public exports/symbols other code imports - lsp_symbols and ast-grep
   import/call shapes, never file-name guesses.
3. Conventions that DEVIATE from stack defaults (configs, naming, layout).
4. Anti-patterns: DO NOT / NEVER / ALWAYS / DEPRECATED comments, forbidden patterns.
5. Hotspots: files >500 lines, high-reference symbols, complexity concentrations.
6. Build/test/dev commands touching these dirs.
DELIVERABLE: EXACTLY ONE file `.omo/init-deep/reports/<id>.md`, <=5k tokens, sections
`# CHUNK <id>` / `## INVENTORY` / `## EXPORTS` / `## CONVENTIONS` / `## ANTI-PATTERNS`
/ `## HOTSPOTS` / `## COMMANDS`; an empty section says `none`.
SCOPE: read only <dirs>; write only your report file. If an AGENTS.md exists in scope,
quote its still-true claims into the matching sections.
VERIFY: the report file exists and every section header is present.
STOP WHEN: the report is written and verified.

TASK: Own subtree <path>: produce its AGENTS.md files for the repo knowledge base.
Steps, in order:
1. Read your chunk reports: .omo/init-deep/reports/<ids>.md. Reports are claims,
   not truth - spot-check real code wherever they conflict or look thin.
2. Score each directory with the init-deep Scoring Matrix; pick locations with the
   Decision Rules (both are in the init-deep skill content loaded with this task).
3. Write each AGENTS.md per the templates and the File Writing Rule. 30-80 lines,
   never repeating parent content.
4. Write .omo/init-deep/digests/<subtree-slug>.md, <=2k tokens: every location
   written (score, one-line role) plus cross-subtree facts the root file must know.
SCOPE: write only inside <path> plus your digest file. Root AGENTS.md is OUT of scope.
VERIFY: every location chosen in step 2 exists on disk within line limits; digest exists.
STOP WHEN: files and digest are written and verified.

AGENTS_LOCATIONS = [

# PROJECT KNOWLEDGE BASE

**Generated:** {TIMESTAMP}
**Commit:** {SHORT_SHA}
**Branch:** {BRANCH}

## OVERVIEW
{1-2 sentences: what + core stack}

## STRUCTURE

## WHERE TO LOOK
| Task | Location | Notes |
|------|----------|-------|

## CODE MAP
{From LSP/ast-grep - skip only if neither exists or project <10 files}

| Symbol | Type | Location | Refs | Role |
|--------|------|----------|------|------|

## CONVENTIONS
{ONLY deviations from standard}

## ANTI-PATTERNS (THIS PROJECT)
{Explicitly forbidden here}

## UNIQUE STYLES
{Project-specific}

## COMMANDS
```bash
{dev/test/build}

**Quality gates**: 50-150 lines, no generic advice, no obvious info.

### Subdirectory AGENTS.md

30-80 lines max. Sections: OVERVIEW (1 line), STRUCTURE (only if >5 subdirs), WHERE TO LOOK, CONVENTIONS (only if different from parent), ANTI-PATTERNS. NEVER repeat parent content; note why the directory earned its file (score, distinct domain).

## Phase 5: Snapshot & Mode

Ask the user: **Local or committed?**

Capture the answer as `USER_MODE_CHOICE`. The explicit answer is authoritative:
- `local` keeps the generated guidance personal to this checkout.
- `committed` lands the generated guidance through a reviewed PR, via the committed-mode PR handoff at the end of this phase.
- If no explicit answer is available, tracked `AGENTS.md` status is the fallback.

Run these commands after the review is complete:

```bash
# Snapshot — create complete JSON with all fields, milliseconds timestamp
mkdir -p .omo
SHA=$(git rev-parse HEAD)
# Count tracked files (NUL byte counting, chunk-boundary safe)
FILES=$(git ls-files -z | node -e 'let c=0;process.stdin.on("data",d=>{for(let i=0;i<d.length;i++)if(d[i]===0)c++});process.stdin.on("end",()=>process.stdout.write(String(c)))')
LOC=$(git ls-files -z -- '*.ts' '*.tsx' '*.js' '*.jsx' '*.py' '*.go' '*.rs' '*.java' '*.kt' '*.swift' '*.rb' '*.php' '*.c' '*.cpp' '*.cs' '*.scala' '*.lua' '*.ex' '*.exs' '*.zig' '*.dart' | xargs -0 wc -l 2>/dev/null | tail -1 | awk '{print $1}')
NOW=$(node -e 'console.log(Date.now())')
USER_MODE_CHOICE="${USER_MODE_CHOICE:-}" && if [ "$USER_MODE_CHOICE" = "committed" ]; then MODE=committed; elif [ "$USER_MODE_CHOICE" = "local" ]; then MODE=local; elif git ls-files --error-unmatch AGENTS.md >/dev/null 2>&1; then MODE=committed; else MODE=local; fi
