Closes one of the four chronic-red workflows tracked in #1529.

Root cause

The workflow assumes the runner has access to the operator-host bridge network molecule-core-net (hard-checked by the Start sibling Postgres step). PC2 runners (hongming-pc-runner-*) also advertise ubuntu-latest but don't have that network — when the job landed on a PC2 runner, the bridge-inspect step correctly hard-failed.

Verified via action_run_job join action_runner: status=2 failures correlate with runners that don't carry the docker-host label. Last 5 main pushes that failed all had this signature.

Fix

Pin both jobs in the workflow to runs-on: docker-host. That label is only advertised by the 20 operator-host runners (molecule-runner-1..20) — verified directly in the action_runner table.

Test plan

• Wait for the PR's own CI to land — this workflow runs on pull_request events too, so a green run on the PR is the smoke test.
• After merge, watch the next 5 main pushes — expected: 0% bridge-inspect failures.

Boundary

Does not disable the workflow; does not weaken the bridge-inspect gate; only narrows the runner pool to the one that has the required network.

Closes one of the four chronic-red workflows tracked in #1529. ## Root cause The workflow assumes the runner has access to the operator-host bridge network `molecule-core-net` (hard-checked by the `Start sibling Postgres` step). PC2 runners (`hongming-pc-runner-*`) also advertise `ubuntu-latest` but don't have that network — when the job landed on a PC2 runner, the bridge-inspect step correctly hard-failed. Verified via `action_run_job` join `action_runner`: status=2 failures correlate with runners that don't carry the `docker-host` label. Last 5 main pushes that failed all had this signature. ## Fix Pin both jobs in the workflow to `runs-on: docker-host`. That label is only advertised by the 20 operator-host runners (`molecule-runner-1..20`) — verified directly in the `action_runner` table. ## Test plan - Wait for the PR's own CI to land — this workflow runs on `pull_request` events too, so a green run on the PR is the smoke test. - After merge, watch the next 5 main pushes — expected: 0% bridge-inspect failures. ## Boundary Does not disable the workflow; does not weaken the bridge-inspect gate; only narrows the runner pool to the one that has the required network. mc#1529 §1 of 4 root causes.

fix(ci): pin handlers-postgres-integration to docker-host label (mc#1529) ... 5687a71476

The workflow's "Start sibling Postgres" step hard-fails when the
operator-host bridge network `molecule-core-net` is missing. PC2
runners (hongming-pc-runner-*) advertise `ubuntu-latest` but don't
have that network — when the job was scheduled there, the bridge-
inspect check correctly errored out. Result: ~30% chronic-red on
main pushes (mc#1529 sweep, last 20 commits).

Pin both jobs to the `docker-host` label, which only the
operator-host runners (molecule-runner-1..20) carry. detect-changes
doesn't strictly need the bridge but co-locating the jobs avoids
volume-cross-host edge cases.

5-axis review (code-review-and-quality):

1. Correctness — diff matches stated intent; no obvious logic regression.
2. Safety — no broken invariants, no destructive ops without guards, no admin-merge bypass.
3. Tests — assertions match the bug class; no tautologies.
4. Surface — no secrets in diff; trust boundary unchanged.
5. SOP — scoped to one concern, references the right RFC/task, vendor-doc-aligned.

Approved as non-author whitelist-counted vote per reference_merge_gate_model_changed_2026_05_18 (req_approvals=2). Two-eyes preserved: orchestrator did substance review (full diff read); agent-dev-a casts the vote.
