Task #390 B-lite — PC2 utilization plan (CTO dispatch)

PC2 native runners (hongming-pc-runner-1..7) cannot execute docker due to a npipe→Linux-container bridging gap. The ubuntu-latest label is advertised by BOTH the Linux operator-host runners (molecule-runner-*) AND the Windows/WSL PC2 runners — placement is non-deterministic, and docker-bound jobs landing on PC2 fail with "Failed to initialize: protocol not available".

This PR makes the docker-need explicit at job level so Gitea Actions only schedules the affected jobs onto runners that advertise BOTH labels.

Audit results (this repo)

Workflow Job Match Action
ci.yml validate-runtime docker info + docker build (graceful-degrade in Docker build smoke test) ubuntu-latest → [ubuntu-latest, docker-host]
ci.yml t4-conformance docker run + docker build (hard-gate via t4 contract probes) ubuntu-latest → [ubuntu-latest, docker-host]

Already-tight (left unchanged)

  • publish-image.yml::publish — already runs-on: [publish, release]

Jobs left bare on ubuntu-latest (no docker exec — safe on PC2)

  • ci.yml::validate-static, validate, tests — Python/static only
  • secret-scan.yml::secret-scan — gitleaks only
  • publish-image.yml::resolve-version — reads .runtime-version

Why per-job

The existing convention in sibling templates is to tighten only docker-using jobs, leaving harmless resolve/static jobs bare so they continue to consume PC2 free capacity. Matching that convention here.

Verification

# pc2-safe: false annotations added inline on every touched job.

Local YAML validation:

ci.yml  validate-runtime  runs-on=['ubuntu-latest', 'docker-host']
ci.yml  t4-conformance    runs-on=['ubuntu-latest', 'docker-host']

## Task #390 B-lite — PC2 utilization plan (CTO dispatch) PC2 native runners (`hongming-pc-runner-1..7`) cannot execute docker due to a npipe→Linux-container bridging gap. The `ubuntu-latest` label is advertised by BOTH the Linux operator-host runners (`molecule-runner-*`) AND the Windows/WSL PC2 runners — placement is non-deterministic, and docker-bound jobs landing on PC2 fail with "Failed to initialize: protocol not available". This PR makes the docker-need explicit at job level so Gitea Actions only schedules the affected jobs onto runners that advertise BOTH labels. ### Audit results (this repo) | Workflow | Job | Match | Action | |---|---|---|---| | `ci.yml` | `validate-runtime` | `docker info` + `docker build` (graceful-degrade in `Docker build smoke test`) | `ubuntu-latest` → `[ubuntu-latest, docker-host]` | | `ci.yml` | `t4-conformance` | `docker run` + `docker build` (hard-gate via t4 contract probes) | `ubuntu-latest` → `[ubuntu-latest, docker-host]` | ### Already-tight (left unchanged) - `publish-image.yml::publish` — already `runs-on: [publish, release]` ### Jobs left bare on `ubuntu-latest` (no docker exec — safe on PC2) - `ci.yml::validate-static`, `validate`, `tests` — Python/static only - `secret-scan.yml::secret-scan` — gitleaks only - `publish-image.yml::resolve-version` — reads `.runtime-version` ### Why per-job The existing convention in sibling templates is to tighten only docker-using jobs, leaving harmless resolve/static jobs bare so they continue to consume PC2 free capacity.

Two jobs were on bare `runs-on: ubuntu-latest` while running docker
commands. The `ubuntu-latest` label is advertised by BOTH the Linux
operator-host runners (molecule-runner-*) AND the Windows/WSL PC2
runners (hongming-pc-runner-*) which cannot execute docker due to a
npipe→Linux-container bridging gap. When such a job lands on PC2 it
fails with "Failed to initialize: protocol not available" —
placement-dependent, not transient.

Fix per task #390 (B-lite from PC2 utilization plan): make the
docker-need explicit at job level so Gitea Actions only schedules these
jobs onto runners that advertise BOTH labels.

ci.yml::validate-runtime (line 153)
  - matched `docker info` + `docker build` in `Docker build smoke test`
  - tightened to `runs-on: [ubuntu-latest, docker-host]`

ci.yml::t4-conformance (line 235)
  - matched `docker run` + `docker build` (hard-gate, no graceful skip)
  - tightened to `runs-on: [ubuntu-latest, docker-host]`

Jobs left bare on `ubuntu-latest` (no docker exec, safe on PC2):
  - ci.yml::validate-static, validate, tests
  - secret-scan.yml
  - publish-image.yml::resolve-version (publish itself already uses
    [publish, release])

`# pc2-safe: false` annotations added on the touched jobs.

core-security APPROVED.

Lens: only YAML/MD changes (no Dockerfile / secrets / prod code). docker-host AND-match narrows runner pool (Linux operator-host only) — tightens placement, does not widen. Lint workflow (op-config#120 only) has permissions: contents: read (least-priv), pinned actions/checkout SHA, fail-closed exit 1, no secrets read. No CWE flags.

Task #390 B-lite security recheck.

APPROVED (core-be empirical review, task #390 B-lite).

Verified scope-clean diff (only .gitea/workflows/ci.yml):

  • validate-runtime: ubuntu-latest -> [ubuntu-latest, docker-host] — docker info/docker build template-test (lines 195/199 of head e138dab9)
  • t4-conformance: ubuntu-latest -> [ubuntu-latest, docker-host] — docker build + docker run -d + docker exec under unprivileged uid 1000 (lines 278-328); hard-gate fail-closed already present

Per-axis: no finding because trivial label tighten with verified docker invocation.

agent-reviewer Five-Axis (CI tweak). runs-on changed to [ubuntu-latest, docker-host] (AND-match) for validate-runtime + t4-conformance so docker-using jobs route only to Linux operator-host runners and exclude PC2 native runners that advertise ubuntu-latest but cannot run Linux containers. No provisioning/runtime behavior change. APPROVED.
