- [Recently Shipped: Test Infrastructure Hardening (2026-06-09/10)](./archive/test_infrastructure_hardening_20260609/) — 4-day test-hell saga closed. 8 phases, 60+ tasks, 314/314 tests green across all 11 tier batches. Fixes 3 root causes: FR1 subprocess health autouse, FR2 live_gui_workspace fixture (per-run timestamped under `tests/artifacts/`), FR3 `_sync_rag_engine` token+dirty coalescing. Plus FR4 set_value hook + FR5 clean_baseline marker. Lineage tracks also archived: `mma_tier_usage_reset_fix_20260610` (4 controller bug fixes), `rag_phase4_sync_fix_20260610` (4-part RAG dim-mismatch + rag_config reset), `workspace_path_finalize_20260609` (precursor). Unblocks `qwen_llama_grok`, `data_oriented_error_handling`, `data_structure_strengthening`, `mcp_architecture_refactor`. Closing report: [../docs/reports/test_infrastructure_hardening_batch_green_20260610.md](../docs/reports/test_infrastructure_hardening_batch_green_20260610.md).
- [Recently Shipped: Live-GUI Test Hardening v2](./tracks/live_gui_test_hardening_v2_20260605/) — All 4 originally-failing live_gui tests now pass. Root cause was bad indentation in `src/gui_2.py:607` (`_capture_workspace_profile` was being parsed as nested inside `_apply_snapshot`); user fixed the indent. The `test_prior_session_no_pop_imbalance` test was refactored to call narrow `render_prior_session_view` (50+ mocks -> 20, runtime 5.79s -> 0.08s).
- [Recently Shipped: Live-GUI Fragility Fixes v1](./tracks/regression_fixes_20260605/) — str/bytes sentinel fix (`ini=b""` -> `ini=""`) in `_capture_workspace_profile`; +1 new regression unit test (`tests/test_workspace_profile_serialization.py`). Did not unblock the live_gui tests due to deeper sync bug.
- [Recently Shipped: Multi-Theme TOML System](./tracks/multi_themes_20260604/) — 8 new theme files, public API (`load_themes_from_disk`, `get_syntax_palette_for_theme`, `apply_syntax_palette`), color-callable convention. See [../docs/guide_themes.md](../docs/guide_themes.md) for the authoring guide.
- [Recently Shipped: Test Regression Fixes (post multi-themes ship)](./tracks/regression_fixes_20260605/) — 11 of 21 failing tests fixed, root cause of remaining live_gui C-level crash identified (`_ini_capture_ready` defer-not-catch pattern).

Last comprehensive doc refresh: 2026-06-10 (27 guide_*.md files, all now indexed in [docs/Readme.md](../docs/Readme.md)). 8 new guides added in the 2026-06-02 docs layer refresh: testing + 7 per-source-file references. Latest addition: `guide_themes.md` (2026-06-04, multi_themes_20260604 ship). The docs_sync_test_era_20260610 track (closed 2026-06-10) verified all 27 guides against the current `src/` source; see [docs/reports/docs_sync_test_era_20260610.md](../docs/reports/docs_sync_test_era_20260610.md) for the closing report. See [docs/Readme.md](../docs/Readme.md) for the full index.
