Acceptance criteria

The artifact is fetched by the triggering run id, not by name alone. MUTATION THAT MUST TURN THE SUITE RED: replace the run-id-scoped fetch with a name-only lookup and the tests must fail. State in the PR body which test caught it and paste its failure output.
A pull request whose head sha matches but whose number does not is REFUSED. MUTATION THAT MUST TURN THE SUITE RED: drop the number from the binding check, leaving only head-sha equality, and the tests must fail. The test must construct two distinct open pull requests sharing one head sha against different bases.
The fetched pull request is cross-checked against the run: its own head sha and its base must match what the workflow_run was triggered for, and a mismatch exits 2 with no comment posted. MUTATION THAT MUST TURN THE SUITE RED: remove the base comparison and the tests must fail.
A malformed or absent artifact fails closed with no comment posted and no review performed. Drive at least: absent file, empty file, non-JSON, a number that is not a positive integer, and a head sha that is not 40 hex. Each must exit 2; a test asserts no HTTP POST or PATCH was issued in any of those cases.
No behaviour change to the same-repository path: a test asserts a workflow_run event whose pull_requests array is NON-empty still resolves from the payload and never reads an artifact at all — asserted by observing that no artifact read was attempted, not by the absence of an error.

Final Report

Resuming context: The prior blocker (reviewer discarding a verdict without opening src/no_human/ci_action/github.py) was fixed on main by d2bf0c1, confirmed by the operator. My prior implementation was intact in the worktree at commit 85d44c8a1 on top of a merge of no-human/7f1660bb-2, but the branch was stale relative to current origin/main. I rebased: since no-human/7f1660bb-2's ci_action content was byte-identical to what landed on main as 4ea03f774, I resolved the three redundant intermediate-commit conflicts by taking the upstream content (verified identical beforehand), then git auto-dropped the fully-redundant final dependency commit as "patch contents already upstream." My feature commit now sits cleanly on top of current origin/main as a single commit 522304b6b, with a diff (vs 4ea03f774) touching exactly the 4 intended files: RELEASE_MANIFEST.txt, src/no_human/ci_action/github.py, src/no_human/ci_action/run.py, tests/test_ci_action.py (1118 insertions, 61 deletions) — no scope creep.

Rest of the coder's report (7 more paragraphs)

Implementation summary:

github.py: added GET-only allowlist anchors _RUN_ARTIFACTS_PATH (/actions/runs/{id}/artifacts) and _ARTIFACT_ZIP_PATH (/actions/artifacts/{id}/zip), deliberately excluding the name-scoped ?name= listing; find_run_artifact() fetches run-id-scoped, re-filters client-side on exact name, refuses on 0/>1 matches/expired/oversize; download_artifact_zip() follows exactly one redirect hop on a credential-free client, size-capped.
run.py: fork path (pull_requests empty) reads trusted workflow_run fields, resolves PR number via _resolve_pr_context (artifact bound to run id + head-sha check), fetches the pull by that number, then _assert_pull_matches_run cross-checks number/head-sha/head-repo/head-branch/base-repo/base-ref — all before the credential is read. Same-repo path untouched.

Mutation evidence (each applied, confirmed RED, then reverted — working tree verified clean afterward):

Run-id-scoped find_run_artifact → name-only lookup: 3 tests failed, including test_fork_workflow_run_artifact_fetch_is_scoped_to_triggering_run_id — WriteSurfaceViolation: refused GET /repos/acme/widgets/actions/artifacts?per_page=100&name=pr-context ... (never the name-scoped .../actions/artifacts?name=... listing, which is not run-bound).
Dropped the number comparison from _assert_pull_matches_run: test_pull_whose_number_disagrees_with_the_artifact_is_refused failed — assert 0 == 2 (ran to EXIT_OK instead of refusing). Full suite: 1 failed, 131 passed.
Removed the base-repo/base-ref comparison: test_pull_base_repository_mismatch_is_refused and test_pull_base_ref_empty_is_refused both failed — assert 0 == 2.

Test run (final gate):

uv run pytest tests/test_ci_action.py -q -n 4
132 passed in 4.35s

uv run python scripts/check_release_manifest.py --strict → OK: 1712 file(s) match RELEASE_MANIFEST.txt.

(a paragraph matched a filtered-phrase list and was removed)

ASSUMPTIONS:

Resolved the stale-rebase conflicts by taking origin/main's content for the 3 intermediate dependency commits (verified byte-identical to my branch's pre-rebase no-human/7f1660bb-2 tip before doing so), then replaying only my own feature commit — a reversible, content-preserving resolution.
origin/main advanced by one more unrelated commit (81f3c2a5b, touching blockers/challenge.py/core/orchestrator.py) while I worked; I did not chase this further churn since it's outside scope and unrelated to ci_action.
MET — The artifact is fetched by the triggering run id, not by name alone — evidence: src/no_human/ci_action/github.py:413-427 (find_run_artifact builds /repos/{repo}/actions/runs/{run_id}/artifacts), github.py:90 (_RUN_ARTIFACTS_PATH allowlist excludes name-only shape). Mutation test: `test_fork

(summary truncated at 4000 characters — full report: nh task show <task-id>)

⚠️ Unresolved: the reviewer reached no verdict after 2 rounds (reviewer reached a verdict without referencing truncated changed file(s): src/no_human/ci_action/github.py). The review gate did not run, so this diff is unreviewed. Never a pass, and never a finding against the coder — a reviewer SESSION that died parks and runs the gate again, anything else goes to a human.

⚠️ Open question: Review the blocker and advise how to proceed.

How I verified this

13 commands recorded - as recorded (shortened, folded onto one line), grouped by kind. No entry asserts a pass or a fail: read the output. Not necessarily everything the session ran.

Not everything recorded is shown: the 12 most recent of those listed are shown with their captured output, and the other 1 command is shown as a command line only.

Not verified: everything below is a limit of this section, listed whether or not it bit this attempt.

no command recognised as e2e, http, typecheck, build was recorded - and a recorded command is shown with its middle omitted, so a check inside the omitted part cannot be ruled out
1 command listed above is shown without its captured output: only the 12 most recent carry it
an entry shows that a command LINE was submitted to the shell and what came back - never that the check recognised inside it RAN, and never that it was the RIGHT command: pytest -k test_nothing prints a clean run, and a recorded command line may name a check the shell never reached yet is still counted - TEN SHAPES WERE DRIVEN against bash 3.2.57 with the check replaced by a marker-printing stub and the marker was absent in every one: a failed &&, a taken ||, an exit, an exec, an exit inside a sourced script, a syntax error that aborts the REST of the line, a multi-line if false, a case that matches nothing, set -e aborting an earlier command, and set -u on an unset variable; that list is MEASURED, NOT EXHAUSTIVE, because this module is not bash, so a kind this section does NOT list as missing is a kind some recorded line named, which is not the same as a kind that ran
the text is the coder's: the session chose the command string and, through echo/printf, can choose the output too. Both are shown as inert text, and no entry ASSERTS a pass, a fail, or an exit status - pytest -q | tail -3 exits with tail's status, Error: Exit code 1 is a line IN THE OUTPUT, and where the harness reported a timeout or an interruption instead of output that report is appended to the captured text in square brackets. Read the output
recognition reads the command line ONLY - it never looks inside what a command runs, so bash -c 'uv run pytest -q' leaves no receipt at all while make test leaves one that names make and not the recipe it ran; and the other way, a check merely NAMED in a heredoc body, or in a quoted string that happens to spell a shell separator, can be recorded as though it ran
commands run inside a spawned subagent are deliberately excluded, so delegated work leaves no receipt here; a command the harness refused to run (blocked, or permission denied) leaves none, because it never ran; and only a command the HARNESS backgrounded leaves no receipt at all - it hands back a task id instead of output. A trailing & YOU wrote is NOT that and is NOT excluded: pytest -q & is recorded and headed test, and may still have been running when the harness returned
the COMMAND and the output are both redacted and bounded before they are stored - an excerpt is not the full log, a credential-shaped string may have been masked out of either, a command over 400 characters is shortened in the middle, each command is displayed on ONE line with its newlines folded to spaces (so it may not re-run as written), and invisible and direction-changing characters are stripped before display; look-alike letters are NOT detected
nothing here checks that these commands exercise the diff - no receipt is compared against the files this PR changes; no interactive UI check was performed (no_human never drives a browser at your change except testing/ui_evidence.py's walk, reported as its own evidence, not a receipt; the only other page it drives is a CI server's login form, and the board it opens without driving, so an e2e entry is the project's harness printing its result, not a human-style walkthrough); and no_human's own test run, CI, and the independent review are separate signals - this section covers only the coder session's own commands
at most 200 receipts are recorded per attempt; past that the observer stops recording, and this section says so above when the limit was reached

See the PR body's Evidence table for the orchestrator's own test run.
