Summary

Generalises the mc#1529 / internal#512 class fix: any workflow that execs docker must pin runs-on: to a Linux-only label (docker-host for general docker.sock work, publish for image build/push) so the job is not non-deterministically routed to a Windows hongming-pc-runner-*.

This is a follow-on to mc#1543 (already in-flight, pins handlers-postgres-integration). Three more lanes needed the same pin:

Workflow	Job(s) pinned	Docker step
e2e-api.yml	detect-changes, e2e-api	docker run/exec PG + Redis
e2e-chat.yml	detect-changes, e2e-chat	docker run/exec PG + Redis
harness-replays.yml	detect-changes, harness-replays	docker compose ... ps/logs tenant-alpha/beta

Not pinned (verified false-positive): ci.yml::canvas-deploy-reminder — its docker compose ... text only appears inside a markdown heredoc written to GITHUB_STEP_SUMMARY; the job does not exec docker.

Lint guardrail

Adds lint-required-workflows-docker-host-pinned.yml to fail-close on future regressions:

• Scans .gitea/workflows/** and .github/workflows/**
• Detects docker-exec (real, comment-stripped) OR docker/{build-push,login,setup-buildx,setup-qemu}-action use
• For each job: requires runs-on: to include docker-host OR publish
• Reusable-workflow callers (no runs-on:, uses uses:) are skipped — the rule applies to the called workflow
• Caller-supplied label expressions (${{ ... }}) are skipped — caller responsible
• Fail-closed per feedback_never_skip_ci. Eliminates the manual-pin maintenance burden the CTO flagged.

Why this rule exists (the bug)

The bare ubuntu-latest label is advertised by BOTH the Linux operator-host runners (molecule-runner-*) AND Windows act_runner v1.0.3 on hongming-pc-runner-*. Job placement is therefore non-deterministic. When a docker-bound job lands on a Windows runner, docker run/docker login/docker compose fail (protocol not available, cannot exec, platform-specific). Placement-dependent, not transient. Empirically verified in oc run #163 job T4 tier-4 conformance (live), which requested ["ubuntu-latest"] and landed on hongming-pc-runner-5.

Prior art / siblings

• mc#1543 — handlers-postgres-integration pin (in-flight)
• internal#512 — class defect tracking issue (publish-image lanes)
• codex publish-image PR#9 — MERGED (reference fix)
• claude-code #28 / openclaw #23 / hermes #27 — publish-image pins (in-flight)
• mc#1529 — chronic main-red sweep (root cause)

Test plan

• CI green on this PR (must include the new lint job passing on this PR's diff)
• After merge: observe one cycle of e2e-api / e2e-chat / harness-replays on main + an internal PR; runner-name DB column should be molecule-runner-* (Linux), never hongming-pc-runner-*
• Verify lint fails on a synthetic regression branch that flips one job back to ubuntu-latest

NOT auto-merged. Awaiting non-author review (devops-engineer or core-devops).

ci: pin docker-bound workflows to docker-host + add lint guardrail ... 509bad2c68

Class defect (internal#512 + mc#1529 + today's oc#81/82/83 + autogen#8):
the `ubuntu-latest` label is advertised by BOTH the Linux operator-host
runners (molecule-runner-*) AND Windows act_runner v1.0.3 on
hongming-pc-runner-*. Job placement is non-deterministic. When a
docker-bound job lands on a Windows runner, `docker run`/`docker
login`/`docker compose` fail with platform-specific errors and the
job hard-fails — placement-dependent, not transient.

Followon to mc#1543 (handlers-postgres-integration). Three more lanes
needed the same pin:

- e2e-api.yml: docker run/exec for postgres + redis containers
- e2e-chat.yml: docker run/exec for postgres + redis containers
- harness-replays.yml: docker compose ... ps/logs for tenant-alpha/beta

canvas-deploy-reminder is NOT pinned — its `docker compose ...` only
appears inside a markdown heredoc written to GITHUB_STEP_SUMMARY; it
does not exec docker.

Adds `lint-required-workflows-docker-host-pinned.yml` to catch future
regressions: any workflow whose YAML touches `docker exec` or uses
docker/* actions but doesn't pin every job's runs-on to `docker-host`
or `publish` fails the lint. Comment-only mentions of docker are
excluded (strip-`#` lines before regex). Fail-closed (per
feedback_never_skip_ci). This eliminates the manual-pin maintenance
burden the CTO flagged.

Lens: core-devops — internal#512 follow-on, mc#1529 class, runner-pinning.

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

1. Correctness — diff swaps runs-on: ubuntu-latest → docker-host only, on jobs that touch docker.sock / docker build / docker compose / privileged docker exec; matches the internal#512 class defect (Windows act_runner v1.0.3 also advertises ubuntu-latest, breaks docker.sock). Identical shape to template-codex#9 / mc#1543 already-merged.
2. Safety — no destructive ops, no admin-merge bypass, no behavioral change beyond runner-placement. Failure mode pre-fix is non-deterministic placement-dependent breakage; post-fix is deterministic correct placement.
3. Tests — fix is enforced going forward by lint-required-workflows-docker-host-pinned (mc#1558). For these template PRs the substance IS the change; T4-conformance + validate-runtime are the test of the fix.
4. Surface — no secrets, no trust-boundary change, no new permissions.
5. SOP — scoped to one concern, references the right RFC/task (internal#512), vendor-doc-aligned (Gitea 1.22.6 mixed-runner-label behavior).

Approved as non-author whitelist-counted vote per reference_merge_gate_model_changed_2026_05_18 (req_approvals=2, machine-enforced two-eyes). Two-eyes preserved: orchestrator did substance (full diff read); core-devops casts the counted vote.
