Why

The runs-on: publish single-label routing in this template's publish-image.yml
is non-deterministic. Both pools advertise the publish label:

  • op-host molecule-runner-publish-{1,2}: working
    (runner-base:full-latest-cloudflared-goproxy-pipe)
  • hongming-pc hongming-pc-runner-publish-* (Windows/WSL): broken
    (runner-base:full-latest-cloudflared-docker-config-fix) —
    docker login --password-stdin fails with:
    Error saving credentials: mkdir /home/hongming: permission denied
    — same EACCES bug class as internal#597 / internal#603 (act_runner HOME
    injection).

When the PC pool picks, publish-image fails non-deterministically. When op-host
picks, it succeeds. Latent risk: random publish-image failures + stale ECR.

Fix

Match the template-codex sibling fix tc#22 (merge commit 0fb25352,
discovered live by a3692d6b on tc#21 publish-image run 79 job 1).

runs-on: [publish, release] (AND-of-labels) routes deterministically to
op-host runners, since they are the ONLY ones advertising BOTH labels
(see op-host /opt/molecule/runners/config.publish.yaml lines 28-29).

Scope

  • 1-line runs-on: change + rationale comment block
  • No new secrets, no perm changes, no behavioral change beyond runner selection
  • Only the publish job affected; the resolve-version job remains ubuntu-latest

Priority

Low-priority hygiene — only manifests when PC-publish picks vs op-host. The
existing setup works correctly when op-host picks first; this just makes it
deterministic so future builds don't randomly land on broken runners.

Cross-refs

  • template-codex tc#22 (merge 0fb25352) — sibling fix
  • a3692d6b (orchestrator) — discovery
  • internal#597, internal#603 — root EACCES bug class
  • op-host config.publish.yaml — label declarations

Reviewers

  • core-devops (workflow infra)
  • core-qa (CI discipline)

Reviewers please verify:

  1. publish + release labels both exist on op-host runners (NOT on PC pool)
  2. [publish, release] AND-of-labels routes to op-host (NOT PC-publish-1/2)
  3. No regression on existing runs
## Why The `runs-on: publish` single-label routing in this template's `publish-image.yml` is non-deterministic. Both pools advertise the `publish` label: - **op-host** `molecule-runner-publish-{1,2}`: working (`runner-base:full-latest-cloudflared-goproxy-pipe`) - **hongming-pc** `hongming-pc-runner-publish-*` (Windows/WSL): broken (`runner-base:full-latest-cloudflared-docker-config-fix`) — `docker login --password-stdin` fails with: `Error saving credentials: mkdir /home/hongming: permission denied` — same EACCES bug class as internal#597 / internal#603 (act_runner HOME injection). When the PC pool picks, publish-image fails non-deterministically. When op-host picks, it succeeds. Latent risk: random publish-image failures + stale ECR. ## Fix Match the template-codex sibling fix tc#22 (merge commit `0fb25352`, discovered live by a3692d6b on tc#21 publish-image run 79 job 1). `runs-on: [publish, release]` (AND-of-labels) routes deterministically to op-host runners, since they are the ONLY ones advertising BOTH labels (see op-host `/opt/molecule/runners/config.publish.yaml` lines 28-29). ## Scope - 1-line `runs-on:` change + rationale comment block - No new secrets, no perm changes, no behavioral change beyond runner selection - Only the `publish` job affected; the `resolve-version` job remains `ubuntu-latest` ## Priority Low-priority hygiene — only manifests when PC-publish picks vs op-host.

The `runs-on: publish` single-label is non-deterministic: hongming-pc-runner-publish-*
runners ALSO advertise `publish` but their runner-base image
(`runner-base:full-latest-cloudflared-docker-config-fix`) fails
`docker login --password-stdin` with:
  Error saving credentials: mkdir /home/hongming: permission denied
— same EACCES bug class as internal#597/#603 act_runner HOME injection.

op-host molecule-runner-publish-{1,2} use the WORKING runner-base image
(`full-latest-cloudflared-goproxy-pipe`) AND advertise BOTH `publish` +
`release` labels (op-host /opt/molecule/runners/config.publish.yaml).
Requiring `runs-on: [publish, release]` (AND-of-labels) routes
deterministically to op-host.

Matches template-codex tc#22 (merge 0fb25352…). Discovered live by
a3692d6b on tc#21 merge-commit publish-image run.

Low-priority hygiene — only fires when PC-publish picks vs op-host; the
existing single-label setup works correctly when op-host picks first.

Five-axis (workflow-infra lens) — APPROVE

1. Substance. Matches tc#22 byte-for-byte in shape: same single-line runs-on: change from publish → [publish, release], same rationale comment block, same cross-refs. Confirmed via tc#22 head 6fb680d7 contents API read: identical AND-of-labels comment block + identical YAML form.

2. Routing correctness. Verified op-host /opt/molecule/runners/config.publish.yaml declares BOTH publish and release labels (lines 28-29), while hongming-pc-runner-publish-* containers only advertise publish (their config.yaml does not include release in the labels array). AND-of-labels deterministically routes to op-host.

3. EACCES bug class. PC-publish runner-base image runner-base:full-latest-cloudflared-docker-config-fix has the broken HOME injection (mkdir /home/hongming: permission denied) — same class as internal#597/#603. Op-host image runner-base:full-latest-cloudflared-goproxy-pipe works.

4. Blast radius. 1-line YAML change to a single job's runs-on. No secret/perm/behavior change. resolve-version job remains ubuntu-latest. If routing is somehow wrong, the worst case is "publish-image fails to start" — same failure mode as today, just deterministic.

5. Risk. Low. Hygiene fix; manifests only when PC-publish wins the schedule race. Sibling tc#22 has been live and clean since merge.

LGTM. APPROVE.

Five-axis (CI discipline lens) — APPROVE

1. Test-mirror & regression safety. This is a placement-determinism fix; no test surface is touched. The change does NOT relax any required check. BP status_check_contexts on main is unchanged (5 contexts: validate / Template validation static+runtime / Adapter unit tests / Secret scan). Post-merge publish-image only fires on push to main → no functional regression risk in PR-gate cycle.

2. Idempotence. Subsequent publish-image runs on op-host (where they already mostly land) will now land on op-host every time. ECR digest under same image-name doesn't change semantics — only WHO produces it.

3. Failure modes. Previously: ~stochastic split between op-host (works) and PC-publish (fails with HOME EACCES). Post-merge: 100% op-host. If op-host runners are down for maintenance the job will wait/queue (vs. failing fast on PC) — that's the correct safety property.

4. Two-eyes preserved. Author infra-runtime-be ≠ reviewer core-devops ≠ reviewer core-qa. Different lenses, different identities. BP required_approvals=2, dismiss_stale_approvals=true honored.

5. Cross-link integrity. tc#22 (0fb25352) is real and merged (verified); referenced sibling discovery a3692d6b and EACCES bug class internal#597/#603 are accurate per session memory.

LGTM. APPROVE.
