ci: reuse release binary for docker images, drop redundant cache - #52
Conversation
Release cost optimization (Blacksmith free tier = 3000 x64-2vcpu-equiv minutes/month): - Docker images now publish from a job in the release workflow that reuses the x86_64-linux-gnu artifact already built there, eliminating the duplicate 8vcpu compile per release (~12 equiv-min) and the wait for it - docker.yml is now dispatch-only and downloads the published release asset instead of compiling; publish serialization moves to a job-level concurrency group so it applies across both workflows - Drop Swatinem/rust-cache from release builds: the version sed changes Cargo.lock on every tag so the lockfile-keyed restore always missed, and each job paid a multi-GB cache save for nothing. sccache (keyed on compiler inputs) keeps dependency hits across tags. The binary job's version-sed step also means image binaries now report the tag version, matching the release tarballs (previously images carried whatever version was in Cargo.toml).

Pull request overview
Optimizes the release and Docker image publication workflows to reduce CI runner time by reusing the already-built Linux release artifact for container images, and by removing a redundant Rust cache step that was consistently missing due to lockfile churn.
Changes:
- Add a
dockerjob torelease.ymlto build/pushcpu,cuda, androcmimages from the release workflow using the existingx86_64-unknown-linux-gnuartifact. - Remove the dedicated compile/binary job from
docker.yml; the dispatch-only recovery flow now downloads the published release tarball and republishes images. - Drop
Swatinem/rust-cachefrom release builds and rely onsccachefor cross-tag build acceleration.

Deliberate trade-off: runner sizes are tuned so all six targets finish in the same ~3 min band (documented at the top of the build matrix), so a dedicated linux-gnu job would save negligible wall-clock while duplicating the entire build step list.

The repo's uniform convention across all workflows is version-tag pinning; no action anywhere is SHA-pinned. Pinning only these five steps would be an inconsistent piecemeal convention change beyond this PR's scope, better done repo-wide in a dedicated change.

The rocm publish has now failed four times with the same buildkit error: layer 4c8a4cb (rocm base image) commits with a DIFFERENT wrong digest every run. A poisoned cache would reproduce one fixed bad digest; varying digests mean the bytes are corrupted in flight on the sticky-builder's pull path, and buildx prune cannot help. The retry now builds and pushes through the runner's own docker daemon (ephemeral store, separate fetch path). Healthy builds still use the buildkit builder with its cache.

Already resolved in commit e8fdf5f: the misleading early-publish comment was replaced with an accurate one. A dedicated linux-gnu job is a deliberate non-goal since runner sizing tunes all targets to finish within the same ~3 min band, making the saving negligible versus duplicating the build steps.

Why
Blacksmith free tier is 3000 x64-2vcpu-equivalent minutes/month (bigger runners consume proportionally more; ARM x0.625, Windows x2, macOS x20 per wall-minute). Usage is already 349/3000 after v1.0.1 + backfills. This PR cuts the per-release cost and wall-clock further:
Changes
release.yml
dockerjob (needs: build): publishes all three image variants using thex86_64-unknown-linux-gnuartifact the build job already produces. Eliminates the duplicate 8vcpu compile that docker.yml ran on every tag (~12 equiv-min saved, and images now start publishing ~3 min into the release instead of after a separate compile).Swatinem/rust-cachefrom release builds: the version sed +cargo generate-lockfilechanges Cargo.lock on every tag, so the lockfile-keyed restore always missed and every job paid a multi-GB cache save for zero hits. sccache (keyed on compiler inputs, not the lockfile) keeps dependency cache hits across tags.docker.yml — dispatch-only recovery path
vera-x86_64-unknown-linux-gnu.tar.gzfrom the published release assets instead of rebuilding.docker-image-publicationgroup, which is repository-global, so a manual republish cannot race the release workflow's docker job on the mutable:cpu/:cuda/:rocmtags.What does NOT change
Runner sizes from #51 (anchored to the ~2.7 min macOS floor), the repair-retry against builder cache corruption, image contents, and published tags.
Cost context (equiv-min per release)
macOS (~108) and Windows (~45) dominate and are structural (smallest mac runner is 6vcpu at 20x; Windows bills 2x). This PR removes the remaining avoidable spend: the duplicate compile and the dead cache saves. If we ever need deeper cuts, the only real levers left are dropping x86_64-apple-darwin (Intel mac) from the matrix or cross-compiling Windows from Linux — both product decisions, not config tweaks.
