Preserve Git split-index checkouts.
When core.splitIndex is enabled, .git/index references .git/sharedindex.*. .dockerignore:15 admits only .git/index and .git/HEAD. The manifest stage copies those files into /gitdir and runs git ls-files with GIT_DIR=/gitdir. Git cannot resolve the missing shared index, so manifest generation can fail in the documented local-clone workflow.
A host-generated manifest is a workaround, so this is a narrow local-build failure. Add !.git/sharedindex.* to .dockerignore, then copy all available shared-index files without failing for non-split-index checkouts:
for sharedindex in /build-context/.git/sharedindex.*; do \
[ -e "$sharedindex" ] || continue; \
cp "$sharedindex" /gitdir/; \
done; \Place the loop after the existing copy at Dockerfile:41.

Correct the .git layer claim in every remote-hub guide.
When the Git-context branch runs, Dockerfile:39-44 copies .git/index and .git/HEAD into /gitdir with cp. That writes the files into the manifest stage’s layer. The runtime stage starts from the base image and receives only selected files from build, so /gitdir is absent from the final runtime image.
Replace the claim that .git is not copied into any image layer. State that the selected Git metadata is confined to the build-only manifest stage and excluded from the final runtime image.
Apply the correction to:

Mark translated remote Compose snippets as build-block overrides.
The canonical English guide states that this YAML replaces only the service’s build block. The translated pages show the same incomplete YAML without equivalent explicit override wording. If copied as a complete Compose file, the omitted ports mapping prevents host access, and the omitted ocx-state and codex-state volumes lose persistent state.
Apply explicit override wording to all seven translated pages: fr#L153-L163, ja#L154-L164, ko#L321-L331, ru#L156-L166, tr#L156-L166, zh-cn#L159, and zh-tw#L140. Alternatively, include the required service and volume settings in each complete example.

Summary
The official Docker build is now self-contained: it builds from a clean Git context, including a remote one, with no host Bun and no preparation command.
pull_policy: buildagainstcontext: https://github.com/lidge-jun/opencodex.git#mainworks as the issue described.A build-only
manifeststage produces the canonical compatibility manifest and accepts exactly two inputs, in order:git ls-files, so the stage produces the same artifact from the selected Git snapshot.A context with neither fails the build with a message naming both inputs. It never falls back to a placeholder — that would defeat the identity the runtime check exists to prove. Both verification passes are preserved: the read-only context is still verified before any
COPYcan dereference a source symlink, and the copied runtime files are still verified inside the image.On admitting Git metadata to the context.
git ls-filesreads the index and never opens an object or a ref, so.dockerignoreadmits only.git/indexand.git/HEAD. That matters: allowlisting.gitwholesale would put this repository's 1.3 GB object store into every localdocker compose buildcontext, where the two files together are about 1 MB. Verified against this repository:.git/index1,129,638 bytes,.git/HEAD20 bytes.objects/andrefs/directories,git ls-files -- src package.json bun.lock scripts/model-metadata.source.jsonreturns the full 1,273-entry inventory.Docker cannot carry empty directories in a context, so the manifest stage copies the two files into a scratch
GIT_DIRit owns and createsobjects/andrefs/there. That also keeps the read-only bind mount pristine and sidesteps the dubious-ownership refusal a context-owned.gitwould trigger for a root build process.Git itself is installed only in the
manifeststage and never reaches thebuildorruntimelayers; the pinned Bun image does not ship it. NoCOPYanywhere in the Dockerfile names.git, and the test now asserts that by scanning everyCOPYline.Supporting changes:
generateCompatibilityVersionManifestandverifyCompatibilitySnapshottake an optional root and output/manifest path so the stage can write outside the read-only mount — both keep their existing no-argument behaviour forprepare:packageand the in-image check.compose.yamlgainspull_policy: buildand theBUILDKIT_CONTEXT_KEEP_GIT_DIRbuild argument, which a remote Git context needs and a local clone ignores.scripts/ci/docker-smoke.tsnow removes any developer-left manifest before building, so the self-contained path is the one CI exercises, and it still restores the host artifact afterwards.tests/service/container-bootstrap.test.tsencoded the old contract — it asserted that no.dockerignoreline re-includes.git, and that the runtime stage copies the host manifest directly. Both are now false by design, so the test was rewritten to the new contract rather than relaxed: it pins the four-line.gitblock verbatim, rejects four broader variants that would reintroduce the object store, requires both manifest inputs and the failing third case, and keeps every existing runtime assertion. Its negative verifier cases (missing, stale, hash-mismatched, extra-source, symlink) are untouched.Verification
ocxbinary, because an earlier local run deleted a real~/.opencodexdirectory. No image was built here..git/index,.git/HEADand emptyobjects/andrefs/produced the completegit ls-filesinventory. That is the assumption the whole design rests on, so it was checked rather than assumed.docker-smokejob onubuntu-latestis the real verifier and it runs on this PR, since a Dockerfile change trips thecipath filter. It now builds from a clean context with no host manifest, so a green run is direct evidence for the issue's primary request.Risks only hosted CI can settle, stated plainly rather than worked around:
BUILDKIT_CONTEXT_KEEP_GIT_DIRthrough to the BuildKit frontend on the Compose version CI runs.docker-smokebuilds from a local checkout, which does not exercise that argument; a genuinely remote-URL context case would need its own CI step.apt-get install gitsucceeds on the pinned digest for both platforms of the image index..gitis a file there rather than a directory. The error message names both supported inputs, so the fix is to generate the manifest on the host as before.Checklist
structure/ops/docs-and-release.mdrecords the build-only manifest stage and the two verification passes..git/config, no refs and no objects, so no remote URL or embedded credential from a developer's Git configuration enters the build. Git is confined to a build-only stage, the runtime stage is unchanged, and no verification was removed or weakened.Closes #4179
