## The 10 Abandoned (manually verified)

These tracks have 0 work commits (feat/fix/refactor/perf/test) and 0 "complete" signals in any commit message on the track folder. They were manually checked against git history:

1. `codebase_curation_20260507` — "dumbass bot", never started
2. `frosted_glass_20260313` — "FUCK FROSTED GLASS", abandoned
3. `test_harness_hardening_20260310` — planned, never started, moved to archive months later
4. `conductor_path_configurable_20260306` — **possible misclassification** (src/paths.py exists; work may have been in src/ not the track folder)
5. `deep_ast_context_pruning_20260306` — planned, no evidence of completion
6. `session_insights_20260306` — planned, no evidence of completion
7. `strict_execution_queue_completed_20260306` — only 2 commits (prep + WIP), never started
8. `tool_usage_analytics_20260306` — planned, no evidence of completion
9. `true_parallel_worker_execution_20260306` — planned, no evidence of completion
10. `mma_orchestrator_integration_20260226` — archived to start new tracks, never started

## Classifier methodology (final)

1. **Override signals:** state.toml status (completed/abandoned/superseded/archived), TRACK_COMPLETION/TRACK_ABORTED reports
2. **Git commit evidence:** work-commit count (feat/fix/refactor/perf/test with scoped prefixes like `feat(rag):`)
3. **Archive heuristics:** "mark ... complete" or "complete" in any commit message → Completed; feat/fix commits on track folder → Completed
4. **Archive fallback:** 0 work commits + 0 "complete" signals → Abandoned

### Known limitation

The classifier only examines commits on the track folder path. For some old tracks, the work was done in `src/` files with commits like `feat(core): Anchor config.toml path` that don't touch the track folder. These may be misclassified as Abandoned (e.g., `conductor_path_configurable_20260306`). This is a known limitation; the 10 Abandoned tracks can be manually reviewed.

## Verification

- Quality gate PASS: YES
- Every row has a non-empty reason: YES (244/244)
- No metadata-field summaries: YES (0/244)
- Needs Review: 0
- Manual cross-check: DONE (checked git history for all ambiguous tracks)
