-## Done

-| Area | State |
-|---|---|
-| Vendored manifest | `gates/vendored.txt`, 8 entries, mirrored into `~/src/utils` |
-| Build artifacts | 189 untracked, `.gitignore` closed, 0 tracked-but-ignored files |
-| no-binaries gate | Path-scoped `.binary-allowlist`; verified blocking AND passing |
-| Markdown | 4 namespaces, all under 250 lines, `CLAUDE.md` written |
-| pre-commit | 15 hooks, green on all files -- `ruff`, `ruff format` and `no-suppressions` landed 2026-08-29 |
-| pre-push | `pre-commit install --hook-type pre-push` via `install.sh` |
-| GitHub CI | `pre-commit` + `md-naming`, both green |
-| run.sh | Root harness + per-course runners over one shared library |
-| `pyproject.toml` | `select = ["ALL"]`, mypy strict, coverage config. **No hook wired up yet** |
-| LaTeX 250-line cap | 19 reports split, every rebuilt PDF verified identical. 1 left |
-| ZPOB | Fixed: builds with `--no-bibtex`, exits 0 |

-| Type | Count | Note |
-|---|---|---|
-| `.py` | 11 | Several GREW during the lint pass, because docstrings and annotations are lines: `NLP/gpt_chunks.py` 911 -> 973, `EARIN/lab2/main.py` 581 -> 647, `PORR/.../linear_algebra_utils.py` 422 -> 553. Split them AFTER the lint work, not during. TRAK is already clear: its three over-cap files were split in the same pass that linted them, each verified by a byte-identical render. `twm_4/TWM_KerasIntro.py` joined the list at 407 lines and should NOT be split: it is an nbconvert export, and a partial one |
-| `.cpp` | 9 | |
-| `.c` | 4 | |
-| `.java` | 2 | |
-| `.tex` | 1 | `ELAC/.../03-building-nfa-...tex`, 418 lines of consecutive tikz figures with no subsection to split on |

-`gates/coverage.tsv` is designed but not written, and there are 125 tests for
