blank lines and `#` lines are ignored; absent means no project; not inherited by second-mate homes). +With the key absent, or for a project that is not listed, a worker is launched and commits exactly as it does without the feature: no hooks setting, no hook, no credential check, and nothing sent. + +With both, `bin/fm-spawn.sh` writes a hooks directory under that ship or scout task's own temporary directory and exports one git setting, `GIT_CONFIG_PARAMETERS`, into that worker's terminal before the worker starts. +The hooks therefore exist only for that worker's own git commands: nothing is written into the project, its git directory, or its git configuration, no other copy of the repository sees them, and cleanup removes the directory with the task's other temporary files. +The directory forwards every other hook to the repository's own, so a project's existing hooks keep running, and the repository's own commit-message hook runs first with its refusal standing. +The check acts only on a commit to the task's own worktree, recorded at launch by its top-level and common git directory: a commit the worker's commands make in any other repository - a test fixture, a temporary repository, a clone, another worktree - is not stopped, is told nothing, and has nothing sent about it. +Second mates are never given the hooks. + +That setting overrides `core.hooksPath` for every git command the worker runs, so a tool that installs git hooks sees the task's temporary hooks directory in place of the repository's own. +`pre-commit install` refuses to install while `core.hooksPath` is set. +`lefthook install` and `git lfs install` write their hook into the temporary directory, where it replaces the forwarder of that name or, for `commit-msg`, the check itself: the hook then runs only for that worker and is removed with the task, and the repository's own hooks directory is not updated. +A listed project whose setup step installs hooks should have them installed in the repository before a worker is launched on it, or stay off the list. + +Code decides first, on the worker's machine: + +- An added line matching a recognised credential format - a private key block, or an AWS, GitHub, Slack, Google, or `sk-` style key - stops the commit, names the file, the line, and the kind, never the value, and tells the worker to remove the credential from the change. + This is the only thing that stops a commit, and Jev has no part in it. +- An added line that assigns a quoted literal to a password, secret, token, or API-key name is often ordinary code, so it only prints one advisory line naming the file and the line, and the commit goes through. +- Merges, rebases, cherry-picks, reverts, `fixup!`, `squash!`, and `amend!` commits, and commits with nothing staged are not checked at all. + +The hook then makes one request carrying up to three yes/no questions, each answerable from the message and the file names alone: is the message filler, does it contradict the staged file names (for example it says only tests changed while other files are staged), and is a staged file unaccounted for by the message. +The last is left out when only one file is staged. +That request carries the commit message (its last 4000 characters when longer) and the staged file names (the first 200), and nothing else: no diff and no line of any staged file's content ever leaves the machine. +Debug leftovers are therefore not judged, because they cannot be told without the content. +The credential patterns above are matched byte-wise, so a byte that is not valid in the worker's locale cannot hide a line from them. +A project taken off the list after a worker was launched is no longer checked by that worker's hook. +A `yes` whose confidence and `yes` probability are both at or above the shared 0.6 floor prints one advisory line; a `no`, a low-confidence answer, a timeout, a transport or API error, and a malformed answer print nothing, and in every one of those cases the commit goes through. + +The setting reaches the worker on the same channel as the task marker, on every runtime backend, and applies wherever a harness runs the worker's git commands with the terminal's environment, which is the same inheritance the task marker already relies on for every supported harness. +A harness or sandbox that withholds that one variable from its shell leaves commits exactly as they are without the feature, and one that blocks network access leaves the credential stop and the secret-literal advisory working while the request fails and the commit goes through. +The pipeline's own fix commits are made outside the worker's terminal and are not checked. + +`bin/fm-commit-check.sh`'s header owns the exact gates, patterns, and bounds, `bin/fm-jev-lib.sh` owns the request, the answer validation, the key handling, and the project list, and [`verification/commit-check.md`](verification/commit-check.md) records the live evidence. + ## Gate defaults (.no-mistakes.yaml) The tracked `.no-mistakes.yaml` sets `test.evidence.store_in_repo: true` and pins `commands.lint` to `bin/fm-lint.sh`, the same owner CI invokes. @@ -496,7 +534,7 @@ OPENAI_API_KEY SSH_AUTH_SOCK ``` -Firstmate retains basic home, executable search, terminal, locale, temporary-directory, and backend routing variables, plus its explicit launch assignments, its ship and scout task marker, and enabled task trace. +Firstmate retains basic home, executable search, terminal, locale, temporary-directory, and backend routing variables, plus its explicit launch assignments, its ship and scout task marker, the [commit check](#commit-check-env-typesafe_api_key-configjev-code-projects)'s git setting for a worker it was exported to, and enabled task trace.
