Collapse per-arch matrix back into single multi-arch push jobs

v1.14.31c's matrix jobs failed on Upload digest with GHESNotSupportedError
— Gitea Actions doesn't support actions/upload-artifact@v4+.
Separately, build-omos arm64 hung silently for 12 min in Set-up job,
likely catthehacker pull contention between concurrent matrix children.

Rather than downgrade artifacts to @v3, collapse the matrix entirely.
docker/build-push-action@v7 with platforms: linux/amd64,linux/arm64
publishes a proper multi-arch manifest in one job, so the
artifact-passing and imagetools create merge dance only existed to
support a matrix split we no longer need.

The matrix was designed around load: true disk exhaustion (v1.14.30b),
but push-by-digest streams straight to the registry with fundamentally
different disk profile. Reclaim step gives enough headroom for the
combined amd64+arm64 push case.

Workflow: 7 jobs → 5. docker-publish.yml: 263 → ~110 lines of YAML.

Also:
- timeout-minutes: 90 on build jobs so hung builds fail explicitly
- BUILDKIT_PROGRESS=plain at workflow level for line-by-line arm64 logs
- AGENTS.md §CI quirks documents the Gitea-specific traps
  (upload-artifact@v3-only, dash-not-bash, build-push-action@v7
  multi-arch convention, reclaim requirement)

+#     toolchains and prunes stale docker state before buildx starts.

+#   An earlier revision split each arch into its own matrix job and used
+#   `actions/upload-artifact` to pass digests to a merge job. On Gitea
+#   Actions, `actions/{upload,download}-artifact@v4+` fails with
+#   `GHESNotSupportedError` — v4 relies on a GitHub-specific Artifact
+#   API that Gitea doesn't implement. Rather than downgrade to @v3 (the

+#   multi-arch push. The matrix only helps when the build literally
+#   cannot fit on one runner, which push-by-digest + reclaim no longer
+#   hits for this image.
+#
+# Gitea Actions gotchas baked into this file:
+#   * `actions/{upload,download}-artifact` must stay at @v3 on Gitea.
+#   * Step scripts run under /bin/sh (dash) — no bash-isms like
+#     ${VAR//a/b}. Use `tr` or explicit `shell: bash`.

+- **Gitea Actions runner has ~40 GB disk, often 70%+ used at job start.** All four `load: true` jobs (`validate-base`, `validate-omos`, `smoke-base`, `smoke-omos`) include a `Reclaim runner disk` step that strips catthehacker-resident toolchains and prunes stale docker state before `setup-buildx-action`.

+- **`docker/build-push-action@v7` with `platforms: linux/amd64,linux/arm64` handles multi-arch push natively in a single job** — produces a proper manifest list, no matrix or merge step needed. An earlier revision split into per-arch matrix jobs with digest artifacts, but that pattern requires `actions/{upload,download}-artifact@v4+` which Gitea Actions doesn't support (see below).
+- **`actions/upload-artifact` and `actions/download-artifact` must stay at @v3 on Gitea.** v4+ uses a GitHub-Enterprise-specific Artifact API; runs fail with `GHESNotSupportedError`. If you need artifacts for a new reason (build logs, SBOMs, etc.), pin @v3 explicitly.

+- **`BUILDKIT_PROGRESS=plain`** is set at workflow level on `docker-publish.yml` so arm64-under-QEMU builds log each layer line-by-line. The default collapsed progress UI hides which step is stalled, which made diagnosing earlier hangs expensive.

Separately, `build-omos linux/arm64` hung silently for 12 minutes in "Set-up job" and then failed with no log output — likely catthehacker image-pull contention between concurrent matrix children on the same runner host.
+  - Rather than downgrade to `actions/{upload,download}-artifact@v3`, collapsed the per-arch matrix entirely. `docker/build-push-action@v7` with `platforms: linux/amd64,linux/arm64` publishes a proper multi-arch manifest in a single job, so the whole artifact-passing and `imagetools create` merge dance existed only to support a matrix split we no longer need.
+  - The original matrix split was designed around `load: true` disk exhaustion (v1.14.30b). With `push-by-digest`/`push: true` streaming straight to the registry — no local unpack — the peak disk story is fundamentally different. Validated in v1.14.31b that the reclaim step gives sufficient headroom for a single-job amd64 build; oracle-reviewed call that this should extend to the combined amd64+arm64 push case.
+  - Workflow goes from 7 jobs to 5 (smoke-base, smoke-omos, build-base, build-omos, update-description). 263 → ~110 lines of YAML in `docker-publish.yml`.
+- **Add:** `timeout-minutes: 90` on both build jobs so a hung arm64 build produces an explicit failure with logs rather than runner-default silent truncation.
+- **Add:** `BUILDKIT_PROGRESS=plain` at workflow level so arm64-under-QEMU build output is line-by-line (the default collapsed progress UI was obscuring earlier stalls).
+- **Add:** `AGENTS.md §CI quirks` documents the Gitea-specific traps encountered this week: `upload-artifact@v3`-only on Gitea, `/bin/sh` is dash, `build-push-action@v7` does multi-arch natively with comma-separated platforms, reclaim step is mandatory on `load: true` jobs.

+## v1.14.31c — 2026-05-01
+
+**CI: fix bash-specific parameter expansion and bump omos size threshold.**
+
+- **Fix:** `Derive platform slug` step in the per-arch matrix build jobs (`build-base`, `build-omos`) used `${PLATFORM_PAIR//\//-}` which is a bash parameter-expansion. The runner container executes step scripts via `/bin/sh` (dash), which errored with `Bad substitution`. Rewrote using `tr / -` which is POSIX and behaves identically. Both `build-base` and `build-omos` matrix jobs were blocked on this on `v1.14.31b`.
+- **Fix:** smoke-test image-size threshold for the `omos` variant bumped from 3000 MB to 3200 MB. The mempalace-toolkit bake-in added ~100 MB to omos; measured 3107 MB on `v1.14.31b`. All functional smoke checks (opencode, node, mempalace CLIs, toolkit wrappers, oh-my-opencode-slim) pass — this is a guardrail recalibration, not a performance concession. The underlying image genuinely grew.
+- The runner-disk reclaim step from v1.14.31b did its job: `smoke-base` and `validate-base` now pass cleanly. Only `smoke-omos` was blocked this iteration, and only on the threshold.
+- No image changes beyond what shipped in v1.14.31. Rebuild of v1.14.31 content only.
+
+## v1.14.31b — 2026-05-01
+
+**CI: reclaim runner disk before `load: true` smoke builds.**
+
+- **Fix:** v1.14.31's publish workflow and the `validate` workflow both hit `No space left on device` on the single-arch amd64 smoke/validate builds (`/opt/uv-tools/mempalace/lib/python3.13/site-packages/hf_xet/hf_xet.abi3.so`, `/usr/local/bin/git-lfs`). Root cause is not the build itself but the `load: true` step: peak disk during export equals tarball + unpacked image + buildx cache, and the image has crossed the ~3 GB threshold where this no longer fits in the ~12 GB of free space the runner container starts with. The v1.14.30c refactor split multi-arch into per-arch push-by-digest jobs (which don't `load`), but the smoke gates still do and still hit the wall.
+  - Added a `Reclaim runner disk` step to all four `load: true` jobs (`validate-base`, `validate-omos`, `smoke-base`, `smoke-omos`). The step strips `catthehacker/ubuntu:act-latest`-resident toolchains we never use (hosted-tool-cache, dotnet, android, powershell, swift, ghc, jvm, microsoft, chromium, boost) and runs `docker system prune -af --volumes` + `docker builder prune -af` against the runner's dockerd before `setup-buildx-action`. Expected reclaim is 6–12 GB depending on what's resident.
+  - Added workflow-level `concurrency: { group: ..., cancel-in-progress: false }` on `docker-publish.yml` so concurrent tag pushes can't race `docker system prune` in one job against an in-flight buildx cache in another.
+  - Pruning is deliberately kept out of the per-arch matrix push-by-digest jobs (`build-base`/`build-omos`) — those don't need it (no `load: true`), and pruning in parallel jobs risks one job nuking another's cache.
+- **Follow-up** (not in this release): image-size reduction via a dedicated `uv tool install mempalace` build stage (strips uv's cache from the final image), pinning `mempalace-toolkit` to a commit SHA with `--depth=1 --filter=blob:none`, and auditing whether `hf_xet` is actually required by mempalace at runtime. These will ship in the next release that rebases on a new opencode version.
+- No image changes. Rebuild of v1.14.31 content only.
+
+## v1.14.31 — 2026-05-01
+
+Bump opencode to 1.14.31.
+
+**CI infrastructure: split multi-arch publish across separate runners.**
+
+- **Fix:** The `publish` workflow exhausted runner disk space on `v1.14.30b` and would have hit the same wall on any subsequent release. Both variants built both architectures on a single `catthehacker/ubuntu:act-latest` container with ~40 GB of shared overlay space, and the peak disk footprint during the nodejs dpkg unpack / git-lfs layer export pushed it over the edge (`No space left on device`). The mempalace-toolkit bake-in from v1.14.30b added the final straw; the underlying issue is that QEMU-emulated arm64 layers were stored alongside the amd64 build on the same runner.
+  - `docker-publish.yml` refactored to the canonical `push-by-digest` + manifest-merge pattern: smoke test (amd64) runs on its own runner, each `(variant × arch)` push target runs on its own fresh runner with `outputs: type=image,...,push-by-digest=true,push=true` (no local image store), then a tiny merge job assembles the multi-arch manifest with `docker buildx imagetools create` from digest artifacts.
+  - Per-runner disk peak is now roughly one-quarter of the old single-job peak. The four Docker Hub tags produced per release (`vX.Y.Z[n]`, `latest`, `vX.Y.Z[n]-omos`, `latest-omos`) are unchanged.
+  - Also parallelizes the amd64 and arm64 builds, so wall-clock time for a release should drop noticeably despite the added merge hop.
+
