fix git notes fetch refspec MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Implements proper remote tracking refs pattern for git notes to prevent non-fast-forward errors when notes have diverged across machines. ## Changes - Add remote tracking refs pattern (+refs/notes/mem/*:refs/notes/origin/mem/*) - Add fetch_notes_from_remote() method for fetching to tracking refs - Add merge_notes_from_tracking() with cat_sort_uniq strategy - Add push_notes_to_remote() for pushing all namespaces - Add sync_notes_with_remote() orchestration method - Add migrate_fetch_config() for idempotent migration from old pattern - Add hook-based auto-sync (opt-in via env vars) - Update /memory:sync command with remote mode and dry-run - Update /memory:validate with refspec configuration check - Add 26 new tests (migration, remote sync, integration, hooks) - Move completed spec to docs/spec/completed/ ## Testing -

5 phases | No change | +| Documents | ~2,000 lines | 2,124 lines | +6% | +| Tests Added | 26 tests | 26 tests | As planned | + +## What Went Well + +1. **Clean Architecture** - The separation between GitOps, SyncService, and commands made implementation straightforward +2. **Comprehensive Testing** - Integration tests caught real-world issues (git version differences, regex vs literal matching) +3. **Idempotent Migration** - The migration runs safely on every session start without breaking existing setups +4. **Complete Documentation** - REQUIREMENTS.md, ARCHITECTURE.md, IMPLEMENTATION_PLAN.md, and 7 ADRs provide full context + +## What Could Be Improved + +1. **Git Version Assumptions** - Initial tests assumed `master` branch, but modern git uses `main`. Fixed by dynamic branch detection. +2. **Config Pattern Matching** - Didn't initially account for `--unset` interpreting `*` as regex. Required `--fixed-value` flag for literal matching (git 2.37+). +3. **Status Check Keys** - The `is_sync_configured()` method returned extra diagnostic keys (`fetch_old`, `fetch_new`) that broke the `all(status.values())` check in `ensure_sync_configured()`. Fixed by checking only core keys. + +## Scope Changes + +### Added +- None + +### Removed +- None + +### Modified +- None (implementation matched specification exactly) + +## Key Learnings + +### Technical Learnings + +1. **Git Refspec Patterns** - Remote tracking refs pattern (`+refs/notes/mem/*:refs/notes/origin/mem/*`) mirrors how git handles branch tracking (`refs/remotes/origin/*`). The `+` prefix allows non-fast-forward updates. + +2. **Git Config Regex Gotcha** - When using `git config --unset` with patterns containing `*`, git interprets them as regex by default. The `--fixed-value` flag (git 2.37+) treats the pattern as a literal string. + +3. **Notes Merge Strategy** - The `cat_sort_uniq` strategy is perfect for append-only data structures like memory capture. It concatenates diverged notes, sorts them, and removes duplicates. + +4. **Progressive Testing** - Integration tests revealed issues that unit tests with mocks didn't catch: + - Default branch name differences across git versions + - Config pattern matching behavior + - Real-world sync workflows with diverged refs + +5. **Service Boundary Design** - The `GitOps` class handles low-level git operations, while `SyncService` orchestrates higher-level workflows (sync = fetch + merge + push + reindex). This separation kept each layer focused and testable. + +### Process Learnings + +1. **ADR Documentation** - Recording 7 Architecture Decision Records during planning saved time during implementation. Each decision had clear rationale and alternatives considered. + +2. **PROGRESS.md Checkpoint System** - The checkpoint file made it trivial to resume work across context boundaries. Task status, timestamps, and session notes provided full continuity. + +3. **Test-Driven Implementation** - Writing tests immediately after implementation caught bugs early: + - Task 5.3 integration tests caught the `GIT_NOTES_REF` constant issue + - Task 5.4 hook tests verified config loading worked correctly + - Task 5.5 revealed the `all(status.values())` logic bug + +4. **Single-Session Velocity** - Having comprehensive upfront planning (REQUIREMENTS.md, ARCHITECTURE.md, IMPLEMENTATION_PLAN.md) enabled completing all 5 phases in one session without context loss or rework. + +### Planning Accuracy + +**Excellent** - The original 5-phase plan with 20 tasks matched implementation 1:1: + +- Phase 1 (Core Fix): 4 tasks → 4 tasks completed +- Phase 2 (Remote Sync): 5 tasks → 5 tasks completed +- Phase 3 (Commands): 2 tasks → 2 tasks completed +- Phase 4 (Hook Auto-Sync): 4 tasks → 4 tasks completed +- Phase 5 (Tests & Polish): 5 tasks → 5 tasks completed + +No tasks were added, removed, or significantly modified. + +## Recommendations for Future Projects + +1. **Dynamic Environment Detection** - When writing tests or scripts that interact with git, always detect the default branch name dynamically (`git rev-parse --abbrev-ref HEAD`) rather than hardcoding `master` or `main`. + +2. **Status Dictionaries** - When a function returns a status dictionary with diagnostic keys, document which keys are "core" vs "informational" to prevent breaking callers that use `all(status.values())`. + +3. **Git Version Guards** - For features requiring newer git versions (like `--fixed-value` in git 2.37+), either: + - Add version detection and fallback logic + - Document minimum git version in REQUIREMENTS.md + - Use feature detection instead of version detection + +4. **Integration Test First** - For anything involving external systems (git, databases, APIs), write integration tests before or alongside unit tests. Mocks can hide real-world behavior. + +5. **Migration Safety** - Always make migrations: + - Idempotent (safe to run multiple times) + - Non-destructive (preserve old config until migration succeeds) + - Automatic (run on session start to catch users who skip `/validate`) + +## Architecture Decisions + +This project made 7 architecture decisions (see [DECISIONS.md](./DECISIONS.md)): + +| ADR | Decision | Outcome | +|-----|----------|---------| +| ADR-001 | Use Remote Tracking Refs | ✅ Eliminated non-fast-forward errors | +| ADR-002 | Use Force Prefix (+) | ✅ Allows fetching diverged notes | +| ADR-003 | Naming Convention (refs/notes/origin/mem/*) | ✅ Consistent with git branch tracking | +| ADR-004 | Auto-Migration on Session Start | ✅ Seamless upgrade path | +| ADR-005 | cat_sort_uniq Merge Strategy | ✅ Perfect for append-only data | +| ADR-006 | SyncService Orchestration Layer | ✅ Clean separation of concerns | +| ADR-007 | Hook-Based Auto-Sync (Opt-In) | ✅ Power user feature without breaking existing workflows | + +All decisions proved correct during implementation.
