# Phase 10: Documentation & Cohesion — Summary

**Phase:** 10
**Plan:** 10
**Status:** COMPLETE
**Completed:** 2026-04-24
**Milestone:** v1.2 Systematization & Cohesion

---

## Phase Overview

Document architecture and design decisions, create migration guide for v1.1 → v1.2, establish unified command documentation template, and perform consistency audit.

## Tasks Completed

| Task | Description | Status |
|------|-------------|--------|
| 1 | Create ARCHITECTURE.md with 10 ADRs | ✅ |
| 2 | Create MIGRATION-v1.2.md complete guide | ✅ |
| 3 | Create docs/COMMANDS.md master reference | ✅ |
| 4 | Unify command/*.md template | ✅ |
| 5 | Consistency audit scripts | ✅ |
| 6 | Manual consistency checklist | ✅ |
| 7 | Verification & state update | ✅ |

## Key Deliverables

1. **docs/ARCHITECTURE.md** — System architecture with 10 ADR records, data flow diagram, directory rationale, and extension guide
2. **docs/MIGRATION-v1.2.md** — Complete v1.1 → v1.2 migration guide with breaking changes, step-by-step instructions, rollback procedure, and FAQ
3. **docs/COMMANDS.md** — Master command reference with Agent ↔ CLI mapping matrix
4. **command/pf-*.md** (5 files) — Unified per-command documentation template
5. **scripts/consistency_audit.py** — Automated hard constraint checks (4/4 passing)
6. **docs/CONSISTENCY-CHECKLIST.md** — Manual soft constraint review checklist

## Verification Results

### Consistency Audit
```
=== Consistency Audit Results ===
[PASS] Check 1: No old command names (0 occurrences)
[PASS] Check 2: No paperforge_lite in Python (0 occurrences)
[PASS] Check 3: No dead links (0 occurrences)
[PASS] Check 4: Command docs structure (0 occurrences)
Passed: 4/4
```

### Test Suite
```
platform win32 -- Python 3.14.0, pytest-9.0.2
 collected 180 items
178 passed, 2 skipped, 0 failed
```

**Note:** Baseline was 155 passed, 2 skipped, 2 pre-existing failures. During verification, discovered and fixed:
- 2 test collection errors (missing `pipeline/__init__.py`)
- 3 test failures (outdated assertions + missing path normalization)
Final result: 178 passed, 2 skipped, 0 failed.

### CLI Verification
- `python -m paperforge --help` — Operational, shows all 10 commands
- `python -m paperforge sync --help` — Operational, shows --selection/--index flags
- `python -m paperforge ocr --help` — Operational, shows run/doctor subcommands

### Documentation Verification
- ✅ docs/ARCHITECTURE.md (26,934 bytes)
- ✅ docs/MIGRATION-v1.2.md (17,648 bytes)
- ✅ docs/COMMANDS.md (4,024 bytes)
- ✅ docs/CONSISTENCY-CHECKLIST.md (2,431 bytes)
- ✅ command/pf-deep.md
- ✅ command/pf-paper.md
- ✅ command/pf-ocr.md
- ✅ command/pf-status.md
- ✅ command/pf-sync.md

## Deviation Log

### Auto-fixed Issues (Rule 1)

**1. Pipeline package import errors**
- **Found during:** Task 7 verification
- **Issue:** `tests/test_base_preservation.py` and `tests/test_base_views.py` failed collection with `ModuleNotFoundError: No module named 'pipeline'`
- **Fix:** Added `pipeline/__init__.py`, `pipeline/worker/__init__.py`, `pipeline/worker/scripts/__init__.py`
- **Files modified:** 3 new files
- **Commit:** `1de282e`

**2. load_export_rows missing storage: prefix normalization**
- **Found during:** Task 7 verification
- **Issue:** BBT-exported bare `KEY/KEY.pdf` paths were not normalized to `storage:KEY/KEY.pdf`, causing PDF resolver to fail
- **Fix:** Added path normalization in `load_export_rows()` — adds `storage:` prefix to relative bare paths
- **Files modified:** `pipeline/worker/scripts/literature_pipeline.py`
- **Commit:** `1de282e`

**3. test_generic_exception outdated assertion**
- **Found during:** Task 7 verification
- **Issue:** Test expected "doctor" in suggestion text, but code was updated to use "diagnose" (Phase 9 command unification)
- **Fix:** Updated assertion from `"doctor" in suggestion.lower()` to `"diagnose" in suggestion.lower()`
- **Files modified:** `tests/test_ocr_classify.py`
- **Commit:** `1de282e`

## Next Steps

Milestone v1.2 is complete. Consider:
1. Tagging release v1.2.0
2. Review v1.3+ candidates in ROADMAP.md (BBT bare path normalization, repair scan performance, OCR provider abstraction)
