# sub-impl-runsreadme — rewrite runs/README.md FLAT (general-purpose · wf_ac43b5ff-7d1)

File: `.claude/workflows/runs/README.md` (FLAT rewrite, 11 sections).

- **Flat naming (khớp `../hmw.js`):** `runs/<id>/` phẳng: `run.md` + `sub-<role>-<i>.md` (raw, prefix `sub-`) + `<stage>-synthesis.md` (verified, suffix). Phân biệt bằng TÊN, KHÔNG subfolder.
- **Cover:** C1 flat tree+table · C2 scaffold@open · C3 git-tracked 2-level (check-ignore exit + ls-files) · C5 3-layer · C6 ledger 2-beat · C7 caveat (no fully-autonomous) · C8 migration (5 old keep subfolder, dual-accept).
- **Detector TAILORED-OUT** documented (Workflow-tool, no CLI bypass-surface; containment git-diff+tracked+orphan-scan; 3 principles considered N/A).
- **Ground-truth flags (honest):** (1) **6 run-folders now** (5 old-subfolder + 1 new flat audit run). (2) SE `.gitignore` KHÔNG có bare `runs` rule → cả 2 path `check-ignore` exit=1; cái "bare `runs/` → 0" là `git ls-files` (no tracked file ở bare path) — documented với full-path guidance + `-v` exit-code trap. (3) parent `workflows/README.md` còn old → flagged (em-main đã fix).
