Original Local Backlog Card

PLATFORM_git-touching-tests-docker-cutover

Why

Wesley now carries the invariant that any test touching real Git must run in a
hermetic Dockerized lane.

The current audit shows Holmes tests and other Git-touching suites still run on
the host, which is how hook-inherited Git environment was able to contaminate a
real branch.

Done when

• every test that shells out to git is classified into the Docker lane
• the Docker lane uses copy-in isolation and does not expose the host repo's
  .git, hooks, remotes, or inherited GIT_*
• the Docker lane obliterates remotes before tests run unless a suite
  intentionally creates a local fixture remote
• hook-driven sanity runs dispatch those suites into Docker instead of running
  them on the host
• tests that do not truly need real Git are downgraded to fake-port/native
  tests rather than being containerized by default

Evidence

• git-touching-tests-are-dockerized
• dockerized-git-tests-copy-in-and-strip-remotes
• 2026-04-17 git-port-plumbing-boundary audit

Triage decision: keep this in Wesley and move it out of the inbox into lane:v0.4.0 / Goalpost: Make It Boring.

Rationale: Docker isolation for git-touching tests is platform reliability work for Wesley's own test suite.

This is scheduled core Wesley work now, not an inbox item. The triage label is being removed as part of this state change.
