# is created here. On every publish after that, the workspace (including
# .git) IS the build context, so the accumulated history — one commit per
# successful agent run, one per publish — survives self-redeploys. Done at
# runtime (not build time) so it also works when the source is bind-mounted
# for local development.

# Isolated worktree for the coding agent. It edits and typechecks here; a

# half-applied edit. Kept outside /workspace so it stays out of the served tree
# and the publish build context. `prune` first drops the stale registration that
# rides along in .git across a self-redeploy (its directory won't exist in the
# fresh container).
