Module container 

The read-oriented container Git backend (0037 DC1b): the same bounded git queries as the remote backend, executed inside a running container through the local engine’s docker exec (GitExec::Container) and parsed by the same wire parsers — discovery and context are the exec-generic cores shared with crate::remote, so no parsing or exit-code mapping is duplicated here. Like the remote path, no mutation verbs exist: container repositories are read-only.

The returned workdir is a path inside the container — never a local path, and no libgit2 handle may be opened against it. The container boundary carries argv as UTF-8 text and caps retained output; both surface as typed refusals from the exec layer, and a truncated stream can never pose as a complete record set.

Functions

context

The pure cached context of an in-container repository: HEAD sha, branch and remotes captured once on a worker, the same GitContext the local and remote paths produce — with RepoTarget::Container as the repo identity. Unborn HEAD and detached HEAD are honest None/name states, distinguished by exit code — never by stderr text.

discover

Discover the repository containing an in-container directory. Ok(None) is the honest “no repository here” — git’s own not-a-repository fatal — while engine failures, missing git and corrupt repositories are typed errors. The returned workdir is a path inside the container, never a local path.
