Mirrors the pi-devbox v0.75.5b fix (2026-05-23) onto the four-variant
pipeline here. The with-pi, omos, and omos-with-pi variants install
upstream npm packages whose *_VERSION build-args defaulted to 'latest'.
When the build-arg string is byte-identical across builds, the layer
hash is identical and the registry buildcache silently reuses the layer
from whatever upstream version was current when the cache was first
populated — same mechanism that shipped pi-devbox v0.74.0..v0.75.5 with
identical image bytes.
Currently masked here because OPENCODE_VERSION is a hard-coded ARG that
bumps every release; parent-chain cache invalidation flushes the
downstream pi/omos layers. Masking would fail on any vN.N.Nb opencode-
version-unchanged release that only bumps pi or omos. Filed last night
as parked followup; fixing preventatively now that #5 (AWS SSO inside
tor-ms22 container) cleared.
CHANGES
.gitea/workflows/docker-publish-split.yml — new resolve-versions job
running 'npm view @earendil-works/pi-coding-agent version' and
'npm view oh-my-opencode-slim version', exposing concrete strings as
job outputs. All six affected jobs (smoke-omos, smoke-with-pi,
smoke-omos-with-pi, build-variant-omos, build-variant-with-pi,
build-variant-omos-with-pi) now consume them as PI_VERSION /
OMOS_VERSION build-args. smoke-base / build-variant-base unaffected.
scripts/smoke-test.sh — new run_expect helper asserting an expected
substring in command output. The pi check uses EXPECTED_PI_VERSION;
the omos check uses EXPECTED_OMOS_VERSION against npm ls -g. Both env
vars are wired from resolve-versions outputs in the smoke jobs. Catches
this regression class on the next release, not four releases later.
Dockerfile.variant — comment blocks above OPENCODE_VERSION (source-
pinned, not subject to the bug), PI_VERSION (CI-resolved), and
OMOS_VERSION (CI-resolved) explaining the cache-hit footgun.
AGENTS.md — new convention bullet under 'Critical conventions' naming
the resolve-versions job + EXPECTED_*_VERSION wiring as the contract
to keep in lockstep when modifying variant build-args.
.gitea/README.md — Step 1 expanded to cover the parallel resolve-
versions job alongside base-decide; pipeline diagram updated.
CHANGELOG.md — Unreleased entry describing the fix, masking mechanism,
and audit footprint.
No image-content change expected on the next release vs what 'latest'
would have resolved to anyway. Purely makes the cache invalidate
correctly going forward.
