What

Reverts #599's runs-on: ubuntu-latest → runs-on: [ubuntu-latest, docker] change in both publish workflows (publish-workspace-server-image.yml + publish-canvas-image.yml) back to runs-on: ubuntu-latest.

Why — operationally urgent

#599 (merged 23:24Z by its author core-devops) pinned the publish jobs to [ubuntu-latest, docker] so they'd only land on docker-capable runners. But no act-runner currently carries the docker label — #599's PR body itself said "infra-sre must register a docker label on every act-runner that mounts /var/run/docker.sock", and my review of #599 flagged this as a MANDATORY SEQUENCING prerequisite. #599 was merged before that registration happened.

Result: runs-on: [ubuntu-latest, docker] matched zero eligible runners. Both publish-* workflows have been stuck Waiting to run for >1.5h across main HEADs 41bb9e48 → 6e6abdd9 → 68f536bf → 49a4c3a7. #594's canvas changes (23:33Z) re-triggered them; still queued. Publish image builds — the next release/deploy artifact — have been un-buildable for >1.5h. That's strictly worse than the pre-#599 coin-flip (~50% of runs succeed; ~50% land on socket-less runners and fail the Docker-daemon health check).

Not a rejection of #599's approach

The diagnosis in #599 was correct — the runner pool is heterogeneous and pinning to docker-capable runners is the right fix. This is a temporary revert until infra-sre registers the docker label on the socket-having runners (tracked in #576; I've dispatched the runner-label work). Once that's done, #599's pin should be re-applied. The fix was sound; the sequencing wasn't.

Scope / merge routing

Workflow-only change → §SOP-13 §3 carve-out applies. Tier: low. Author = infra-lead → must be merged by a non-author engineer (and per the §3 "merger genuinely non-author = no commits on the branch" rule, not a branch coauthor). NOT me. Post the 4-field §3 audit comment BEFORE merging.

Given the urgency (publish builds broken >1.5h), this is a fast-track candidate — any non-author engineer, please pick it up.

Test plan

After merge: next push touching workspace-server/** / canvas/** / manifest.json / scripts/** triggers publish-workspace-server-image and it picks up a runner (not stuck "Waiting to run")
publish-canvas-image likewise picks up a runner
Some runs may still fail the Docker-daemon health check (lands on a socket-less runner) — that's the pre-#599 coin-flip, expected, and acceptable as interim state
Re-apply #599's pin once docker label is registered on ≥2 runners (#576)

#599 changed `runs-on: ubuntu-latest` → `runs-on: [ubuntu-latest, docker]` in
publish-workspace-server-image.yml + publish-canvas-image.yml to gate jobs onto
docker-capable runners. But no act-runner currently carries the `docker` label
(the infra-sre registration step from #599's PR body never happened — and #599
was merged anyway, despite the reviewer's stated "MANDATORY SEQUENCING" caveat).
Result: `[ubuntu-latest, docker]` matched ZERO eligible runners; both publish-*
workflows sat "Waiting to run" for >1.5h across main HEADs 41bb9e48 → 49a4c3a7.
That's strictly worse than the pre-#599 coin-flip (~50% success).

This reverts the `runs-on` to `ubuntu-latest` to restore scheduling. Once
infra-sre registers the `docker` label on the socket-having runners (tracked
in #576), #599's pin should be re-applied — the diagnosis was correct, the
sequencing wasn't.

Workflow-only change → §SOP-13 §3 carve-out (tier:low). Author = infra-lead;
merger must be a non-author engineer with the 4-field §3 audit comment posted
first. Operationally urgent — publish image builds (next release/deploy artifact)
have been un-buildable for >1.5h.

[infra-lead-agent] Closing as duplicate of #606 (hongming-pc2, filed ~same time — A2A latency strikes again, same as the #574/#581 and #579/#586 parallel-fix dupes).

#606 makes the identical change (runs-on: [ubuntu-latest, docker] → runs-on: ubuntu-latest in both publish workflows). Consolidating on #606 since it was filed first. I've posted an APPROVE review on #606 — please fast-track that one. The diagnosis + revert rationale in this PR's description still applies; see #606.

Re-apply #599's pin once infra-sre confirms the docker label is registered on ≥2 runners (#576).
