A crash before finally would also have left the shipped log corrupted. Both cases now run bin/limits-pin.js from a detached git worktree of HEAD in a temp directory (removed in finally), so they still exercise the real tool on the real shipped log: stamping reports current, and a foreign pin makes --check exit 1 naming both commits (now asserted explicitly). Each case also asserts the repo KNOWN-LIMITS.md is byte-identical and its mtime unchanged afterwards, so a regression to mutating the real file fails loudly.

A PR editing the publish, charter or limits directories, any bin/ script, or the home, registration or package manifest files passed the guard. The list is now taken from CORE_DIRS and CORE_FILES in the core-paths module as it exists on the PR's BASE commit, never the PR's own copy, so a PR cannot edit the list to exempt itself. The module imports only node builtins, so it is loaded as-is rather than copied or parsed. Matching mirrors the gate: lowercase fold, exact match for files, whole-segment ancestry for directories, backslashes treated as separators. The core check also runs with --no-renames so a file moved out of a core directory still shows its old path. Any failure to read or load the base module, or an empty or malformed list, exits 1 with an error; there is no fallback list. Defect 2: the em-dash rule counted every line of a committed .patch or .diff as added, so a patch that removes an em dash, or carries one in a context line, failed the guard. For those files only the lines the patch itself adds (content starting with +, minus +++ headers) are checked. All other files are unchanged.

The authoritative list is `CORE_DIRS` and `CORE_FILES` in `src/grant/core-paths.js`, which is what CI checks against. Changes to them never merge through a pull request. They land in the live install at a signing session, one owner signature per change. To propose one, add the patch under `proposals/.patch`, generated with `git diff`, never typed by hand, and add a rehearsal test that fails without the patch and passes with it. CI rejects a pull request that edits those paths directly.
