ruff was never wired into this repository: no target, no CI step, no pin. It reported 45 findings across sources and tests, so nothing enforced what the codebase already mostly followed. Adds `make ruff` (check + format --check), `make ruff-fix`, and `make lint` as its alias, and makes `make test` run lint as a fourth parallel spur. The CI workflow calls `make test`, so it is covered there too. The linter is pinned in a `lint` extra: a ruff minor bump changes which rules fire, and with the suite gating on a clean run an unpinned linter would fail it on an unrelated day. The 45 findings are fixed rather than configured away. Three needed a decision instead of the mechanical fix: - The generation timestamp keeps its local wall clock (DTZ005 waived). Generations sort by that name, and UTC would order new ones before the existing ones wherever the offset is positive - "newest generation" is what every restore path selects on. - The per-volume `copy` closure now binds volume_name and vol_dir as default arguments (B023). It only worked because it is called inside the same iteration. - The two CLI top-level handlers keep their blind except (BLE001 waived): turning any failure into exit 1 is what a CLI boundary is for. The two in run.py did not need it and were narrowed to what they actually catch. Also drops the comments that restate the code: the section banners in restore/__main__.py, the filename repeated as line 1 of nine test files, step narration above the statement it narrates, and a block in app.py documenting parameters that had moved to another module. What names a trip-wire stays - the snapshot destination rule, the mysql-binary absence in MariaDB 11 images, the session-scoped FOREIGN_KEY_CHECKS, the spooled temp file for multi-GB dumps, and the negative control that loses its discriminating power if it ever passes.
