ops(queue): enroll mhtml-etl-gateway in queue-health evidence

[seonghobae]

Parent owner: #1150. Downstream scientific consumer: ContextualWisdomLab/TEPP#536. Canary: ContextualWisdomLab/mhtml-etl-gateway#95.

Finding

ContextualWisdomLab/mhtml-etl-gateway#95 independently reproduces the organization Actions admission/runner queue class while canonical queue-health owner #1150 cannot observe that repository because its explicit bounded allowlist omits it.

Fresh exact canary is mhtml-etl-gateway#95@488ce69863148edd9bafdc54c40a2b2df1c4a8ef. Repository Quality run 34957509223 materializes Python 3.11–3.14 jobs, but all four remain queued with runner_id=0, empty runner name, and steps=[]. Exact-head Security Scan 34957509235, SAST Semgrep 34957509185, and CodeQL PR 34957509212 are also queued. TEPP #527 separately reproduces pre-checkout queueing on exact 8b5462dd547773688eed282a3ff373247778f4a1.

This is owner-side admission evidence, not permission for leaf reruns, no-op commits, runner-selector churn, cancellation, predecessor-status transfer or gate weakening.

RED → minimal repair

Parent exact authority is #1150@42bb922f03bf75aed1bc1931d9fbaf04a5433e20.

RED ce1c60bb1db1edaec71b55986ba771baae5c303a enrolls ContextualWisdomLab/mhtml-etl-gateway in config/actions_queue_health_repositories.json while intentionally leaving the exact-equality owner contract unchanged. On an executing runner, existing test_queue_health_allowlist_is_explicit_and_bounded must reject that mismatch.

Causal fix 22d6a9679f015cd2571ae859d1925d92c3e0d676 updates only tests/test_actions_queue_health_contract.py to admit the reviewed repository in the same explicit bounded list.

Effective delta against the parent is exactly two owner paths:

• config/actions_queue_health_repositories.json
• tests/test_actions_queue_health_contract.py

Collector logic, workflow triggers, runner selectors, cancellation/rerun behavior, required gates and observed leaf repositories are unchanged. The two commits were created as ordinary parent→RED→fix history and only the final fix head was published as the branch, avoiding a redundant intermediate hosted run.

Promotion boundary

Keep Draft. Enrollment is not incident resolution and no predecessor result transfers. GREEN requires canonical #1150 to normally integrate this two-path delta and the existing read-only collector to observe mhtml-etl-gateway using current repository/PR/head/workflow/job identities. Exact-head checks and review on this child remain authoritative for this child only.

No self-approval, administrator bypass, force update, destructive rebase, workflow-source copy, cancellation, blind rerun, no-op freshness commit, runner-selector churn, synthetic status or gate weakening is authorized.

Supersession note: unique mhtml enrollment delta carried to successor #2243 on current main (head 30a5e73e6418e2e9e655b0ff4c30b11996333612). This draft remains open pending verified carryover after #2243 merges; do not close on redundancy alone.

Superseded — closing (tree-verified)

This draft's unique valid delta was enroll ContextualWisdomLab/mhtml-etl-gateway into config/actions_queue_health_repositories.json and the matching allowlist assertion in tests/test_actions_queue_health_contract.py.

Carryover proof on origin/main (not ancestry):

git grep -lF "ContextualWisdomLab/mhtml-etl-gateway" origin/main -- config/actions_queue_health_repositories.json
# → origin/main:config/actions_queue_health_repositories.json

git grep -lF "ContextualWisdomLab/mhtml-etl-gateway" origin/main -- tests/test_actions_queue_health_contract.py
# → origin/main:tests/test_actions_queue_health_contract.py

Successor merge: #2243

Three-dot note: git diff --stat origin/main...22d6a9679f015cd2571ae859d1925d92c3e0d676 is still non-empty because this branch forked from a pre-enrollment allowlist tip; the three-dot patch only re-adds strings already present on main (plus trailing-newline noise). Redundancy alone is not the close reason — content proof above is.

Closing per AGENTS.md "Verifying a superseded — closing claim."

[seonghobae]

Closed as superseded: enrollment string ContextualWisdomLab/mhtml-etl-gateway is on origin/main via #2243.
