## Overview

Transform PaperForge Lite from a functional-but-scattered prototype into a cohesive, user-centric system where commands are unified, workflows are intuitive, and the architecture feels intentional rather than assembled.

## Phases

### Phase 9: Command Unification & CLI Simplification

**Goal:** Implement unified `/pf-*` namespace and simplify CLI commands.
**Status:** Done (2026-04-24)
**Requirements:** SYS-01, SYS-02, SYS-07 (3/7)
**Tasks:** 7 (0-6)

Plans:

- [x] Rename Python package (`paperforge_lite` → `paperforge`)
- [x] Create shared command modules (`paperforge/commands/`)
- [x] Refactor CLI to use command modules
- [x] Create new `/pf-*` agent command docs
- [x] Remove old `/LD-*` and `/lp-*` command docs
- [x] Update AGENTS.md and tests
- [x] Verification and cleanup

### Phase 10: Documentation & Cohesion

**Goal:** Document architecture, create migration guide, ensure consistency.
**Status:** Done (2026-04-24)
**Requirements:** SYS-03, SYS-04, SYS-05, SYS-06 (4/7)
**Tasks:** 7

Plans:

- [x] Create ARCHITECTURE.md with 10 ADRs
- [x] Create MIGRATION-v1.2.md complete guide
- [x] Create docs/COMMANDS.md master reference
- [x] Unify command/*.md template
- [x] Consistency audit scripts
- [x] Manual consistency checklist
- [x] Verification & state update

## Milestone Summary

### Key Accomplishments

1. **Unified Agent Command Namespace** — All agent commands now use `/pf-*` prefix (`/pf-deep`, `/pf-paper`, `/pf-ocr`, `/pf-sync`, `/pf-status`). Old `/LD-*` and `/lp-*` prefixes completely removed with no aliases — clean break for v1.2.

2. **Simplified CLI Commands** — `paperforge sync` combines `selection-sync` + `index-refresh` with `--selection`/`--index` flags for partial runs. `paperforge ocr` merges `ocr run` + `ocr doctor` with `--diagnose` for standalone diagnostics.

3. **Shared Command Modules** — Extracted all CLI logic into `paperforge/commands/` package with 6 modules (sync, ocr, deep, repair, status, __init__), reusable by both CLI and Agent layers.

4. **Package Rename** — Python package unified under `paperforge` name (was `paperforge_lite`). 98 Python references and 377 markdown references updated across 91 files.

5. **Architecture Documentation** — Created `docs/ARCHITECTURE.md` with 10 ADR records, data flow diagrams, directory structure rationale, and extension guide for contributors.

6. **Migration Guide** — Created `docs/MIGRATION-v1.2.md` with breaking changes table, 7 migration steps, import path changes, rollback instructions, and 9 FAQ entries.

7. **Consistency Audit** — Automated audit script (`scripts/consistency_audit.py`) with 4 checks (old commands, package name, dead links, doc structure) — all passing. Manual checklist (`docs/CONSISTENCY-CHECKLIST.md`) for soft constraints.

### Requirements Coverage

| Requirement | Status | Notes |
|-------------|--------|-------|
| SYS-01: Unified Agent Command Namespace | Complete | All `/pf-*` docs created, old docs removed |
| SYS-02: CLI Simplification | Complete | `sync` and `ocr` unified, backward compat aliases maintained |
| SYS-03: Agent↔CLI 1:1 Mapping | Complete | docs/COMMANDS.md master reference created |
| SYS-04: Architecture Documentation | Complete | ARCHITECTURE.md with 10 ADRs |
| SYS-05: Migration Guide | Complete | MIGRATION-v1.2.md with rollback instructions |
| SYS-06: Consistency Audit | Complete | 4/4 automated checks passing |
| SYS-07: Test Coverage for Unified Commands | Complete | 178 tests passing, 0 failures |

### Key Decisions

- **Aggressive Migration:** Old commands completely removed with no aliases or deprecation warnings — clean break for v1.2
- **Unified Sync:** `paperforge sync` runs both selection-sync and index-refresh by default
- **Merged OCR:** `paperforge ocr` combines run + diagnose; `--diagnose` for standalone
- **Command Modules:** All CLI logic extracted into `paperforge/commands/` for reuse
- **Package Rename:** Python package unified under `paperforge` name

### Issues Resolved

- Two conflicting command namespaces (`/LD-*` vs `/lp-*`) unified into single `/pf-*`
- `selection-sync` + `index-refresh` always run together but were separate commands
- `paperforge_lite` package name inconsistent with CLI brand
- No architecture documentation for contributors
- No migration guide for existing users upgrading from v1.1

### Issues Deferred

- BBT bare `KEY/KEY.pdf` path normalization — deferred to v1.3 (ZPATH-01/02/03 marked Partial)
- OCR provider abstraction — deferred to v1.3+ (currently PaddleOCR-only)
- Repair scan performance optimization — deferred to v1.3+
- Obsidian plugin (TypeScript) — future milestone when frontend needed

### Technical Debt

- `pipeline` module import errors in `test_base_preservation.py` and `test_base_views.py` — tests reference non-existent module layout (auto-fixed by adding `__init__.py` files during Phase 10 verification)
- `test_pdf_resolver.py` attachment path normalization — pre-existing issue unrelated to v1.2
