feat(ratchet): a commit-provenance row, so a table cannot look current on a superseded commit - #761
Conversation
…t on a superseded commit #759's ratchet comment ended `checked-out HEAD `13fa724278bf`` while that PR's head was `4632f979f164`. `13fa7242` is GitHub's synthetic merge commit (parents `3126ac1b` = base tip, `4632f979` = PR head) — a sha that appears on no PR page anywhere. The table named a commit nobody could look up, so a reviewer could not tell it from one measured three pushes ago. That is how #753 was nearly reviewed on an all-green belonging to superseded `6ea5b395`. New leading row, `commit provenance`: * names the PR-head sha the checkout stands for, proved against the commit graph (`git rev-list --parents -n 1 HEAD`) rather than asserted — the merge ref's second parent; * compares it to the PR's head read LIVE from `repos/{owner}/{repo}/pulls/{n}` at collect time, not to the event payload, which is fixed when the run starts and so always agrees with itself; * renders RED on a mismatch, on a checkout that is not the triggering commit, and when the live head could not be read at all — a run asked to prove it is current and unable to has a finding, not a capability gap. The one `n/a` is a non-PR invocation. The footer now labels both shas instead of printing one unlabelled `HEAD`, and the `provenance` row's notes say its sha is the checkout's, because two rows now print two different shas. Workflow: `fetch-depth: 2` on the table job — at depth 1 the merge ref is the shallow boundary and git reports it as having no parents, so the row could not tell "right commit" from "git cannot say". The new hand-off step reads only the event payload and the REST API, never the PR's tree, so the gated change cannot edit its gate (Macroscope #753 HIGH). Premise checked, not executed: the trigger ALREADY re-rendered on every push — `synchronize` is in `types` and has been asserted since #752. `test_every_push_to_the_pr_re_renders_the_table` passes on d04cb31. What was missing was not the re-render but the PROOF, which is what this row adds; the test now also pins the absence of a `paths` filter, which would silently skip pushes. Proof the tests are real: the new file run against `d04cb310` fails 25 tests, headline `test_main_reds_the_whole_table_when_it_was_measured_on_a_superseded_commit`: `__main__.py: error: unrecognized arguments: --measured-sha d04cb31… --pr-head-sha dddd…`. 133 pass on this branch. `!cancelled()` holds (the new step is in the parametrized writer list); one comment per PR holds; both still asserted by pyyaml parsing, never occurrence counts.

Assert the two shas, not only the notes text.
The name and docstring of this test state that a reader can tell the merge ref from the PR head. The assertions read two substrings of PROVENANCE_NOTES only. A regression that printed the merge ref in the commit row value would keep this test green.

…pty commit hand-off Both from CodeRabbit's review of #761. **Major, accepted.** `actions/checkout@v4` writes the job token into `.git/config` by default, and this workflow's token carries `pull-requests: write` — enough to rewrite the ratchet comment it guards. The `table` job then runs `python -m build --wheel`, which executes the PR's own build backend, so on a same-repo PR that code could read the token. That is the same failure class as the verifier rule this workflow already follows: the gated change must not be handed the means to edit its gate. `persist-credentials: false` on all three checkouts, not just the one CodeRabbit flagged — a per-job exception is how this comes back. Verified safe first: every git call in all three jobs is local (`cat-file`, `diff`, `rev-parse`, `rev-list`, `status`) and `gh api` authenticates through $GH_TOKEN, never git's config. A test asserts both halves, so a later `git fetch` cannot silently start needing the credential that was given up. **Trivial, rejected — and hardened the other way.** CodeRabbit proposed `COMMIT_ARGS=("${COMMIT_ARGS[@]+"${COMMIT_ARGS[@]}"}")` to survive `set -u` on bash 3.2. The array is structurally never empty (the resolve step writes `--measured-sha` plus a value before any branch), CI runs bash 5, and adding the guard to one of two identical read loops would make them diverge. More to the point, the suggestion is backwards: if that file were ever empty, the collector would get no commit flags and render `n/a — not a pull-request run`, which on a PR run is a FALSE GREEN — precisely the substitution this table exists to forbid. Suppressing the error would make that outcome more likely, so the step now fails on an empty hand-off and lets the guarantee step publish "this run measured nothing". 138 passed. `ruff check` and `ruff format --check` clean; `shellcheck` clean on the changed step.

…t edit its gate" to what holds Reviewer 79c16541 returned CHANGES_REQUESTED on 9e6cbff with two required items. Both are the same shape, and it is the shape this PR exists to close: a claim wider than the thing backing it. **F1 — the footer labelled the SUPERSEDED sha "PR head".** `probe.measured_sha` is the commit the run was TRIGGERED for, not the PR head. On the one path the row exists for, the footer asserted the stale sha was the PR head four lines under a row saying it was not; on `--pr-head-unresolved` it printed a PR head the run had just said it could not read. That is #759's defect re-committed one line lower. Every sha in the footer is now labelled for what it is — `measured <x> · PR head <y> · checkout <z>`, `PR head unread` when the live read failed, and neither sha at all on a non-PR run. Rendered all three; four footer tests, where one previously exercised only the GREEN probe. **F2 — "the PR cannot edit the check that gates it" is false, and I repeated it in three places.** On a `pull_request` event GitHub runs the workflow AND these scripts from the PR's merge ref, so the comparator is the PR's own code and an author could make `row_commit_provenance` return GREEN unconditionally. The reviewer proved it for this repo rather than arguing it: `ratchet.yml` first landed on main in `0bf01672`, yet ten `pull_request` runs exist on `wt/w14-ci-ratchet-table` before the file was on main. What holds is narrower and is still the substantive half: no INPUT to the row comes from the PR's tree — event payload, live REST read, commit graph — so the row cannot confirm itself from material the PR controls. Diff-reviewable, not tamper-proof; the wording now says exactly that in the workflow, the collector and the test. `test_nothing_in_the_commit_hand_off_comes _from_the_pr_tree` is renamed to `test_no_input_to_the_commit_row_is_read_from_the_pr_tree` — it never asserted the claim in its own docstring — and a new test fails if either overclaim comes back. Also from the same review, all optional and all taken: * **F4** `measured in lineage` accepted `lineage[1]`, the BASE tip, which proves nothing about the PR head. Replaced with `checkout_stands_for()`, which checks by POSITION: the checkout is either `measured` itself or GitHub's merge ref, where the PR head is always the second parent (verified on #759 and in a local shallow-fetch experiment). A one-parent checkout whose parent is `measured` is a descendant, not a merge ref, and is now rejected. * **F5** three attempts with backoff on the live head read. The verdict stays fail-closed RED — proving currency is the row's whole value — but one transient blip should not paint a fine PR red, and a job that is sometimes red for no reason teaches reviewers to ignore it. Dry-run with a stubbed 502: two retry notices, then `returned no head sha in 3 attempts (HTTP 502: Bad Gateway)`. * **F6** `SHA_PATTERN` no longer duplicated inline in `git_head()`. 144 passed. `ruff check` and `ruff format --check` clean; `shellcheck` clean on the changed step.

The receipt this PR is built on
PR #759's ratchet comment ends:
#759's head is
4632f979f1642fb95270c3006abc1eae48ec5ae3.13fa7242is GitHub's synthetic mergecommit —
gh api repos/EtanHey/brainlayer/commits/13fa724278bfgives parents3126ac1b(base tip) and4632f979(PR head). The table named a commit that appears on no PRpage anywhere. A reviewer could not tell that table from one measured three pushes earlier. That
is exactly how #753 was nearly reviewed on an all-green belonging to superseded
6ea5b395.What changed
New leading row,
commit provenance(scripts/ci_ratchet_table.py):measured \4632f97` == PR head · checkout `13fa724278bf``Two shas, from two sources on purpose:
--measured-sha=github.event.pull_request.head.sha, fixed for the life of the run;--pr-head-sha= read live fromrepos/{owner}/{repo}/pulls/{n}when the table is collected.A run that compared the event payload against itself would agree with itself forever. The live read
is the only way a run finds out it has been overtaken.
The measured sha is proved, not asserted.
git rev-list --parents -n 1 HEADgives(HEAD, *parents); the row accepts the measured sha only if it is the checkout, or is the mergeref's second parent — the position GitHub always puts the PR head in.
so the PR's tree cannot forge the answer to the check that gates it— CORRECTED. An earlierrevision of this body claimed that. It is false, and reviewer
79c16541disproved it for thisrepo:
ratchet.ymlfirst landed on main in0bf01672, yet tenpull_requestruns exist onwt/w14-ci-ratchet-tablebefore the file was on main. On apull_requestevent GitHub runs theworkflow and
scripts/ci_ratchet_table.pyfrom the PR's merge ref, so the comparator is thePR's own code and could be rewritten to answer GREEN. Macroscope's #753 HIGH settled the verifier
script; it did not settle the comparator.
What actually holds, and is the substantive half: no INPUT to this row comes from the PR's tree —
the event payload, the live REST read and the commit graph are all outside it — so the row cannot
confirm itself from material the PR controls. Diff-reviewable, not tamper-proof, and the wording
in the workflow, the collector and the test now says exactly that.
Workflow (
.github/workflows/ratchet.yml):fetch-depth: 2on the table job. At depth 1 themerge ref is the shallow boundary and git reports it as having no parents at all, so the row
could not distinguish "this is the right commit" from "git cannot say".
Footer and notes. The footer now labels both shas (
PR head … · checkout …) instead of printingone unlabelled
HEAD, andprovenance's notes say its sha is the checkout's — because two rows nowprint two different shas and a reader who cannot tell them apart is back in #759 with more numbers.
Premise checked, not executed
The brief said "the trigger does not guarantee a re-render per push." That premise is false as
stated.
synchronizehas been intypessince #752 andtest_a_label_added_after_the_pr_opened_actually_re_runs_the_workflowalready asserted it;test_every_push_to_the_pr_re_renders_the_tablepasses ond04cb310. Every push already fireda run that re-rendered the comment.
What was missing was not the re-render — it was the proof, which is this row. The new test still
earns its place by pinning the two things nothing asserted: that no
paths/paths-ignorefilterexists (one would silently skip pushes that touch nothing on the list, leaving the previous commit's
table standing on a moved branch) and that
cancel-in-progressis on.One real gap this does not close, stated rather than papered over: on a PR that trips the macOS
parity gate,
tablewaits onsignatures(timeout-minutes: 90), so the comment is refreshedlate. The table still re-renders per push; during that window the standing comment belongs to the
previous commit.
This row makes that window visible instead of silent— CORRECTED (reviewer79c16541, F3).It does not. While
tablewaits, the standing comment is the previous run's: GREEN, naming theprevious PR head. Nothing turns RED and nothing announces the wait. What the change buys is that a
reader can compare a real PR-head sha against the PR's actual head by hand — impossible on
#759, where the only sha printed was the merge ref. Partial mitigation, not visibility. Decoupling
the two jobs is (b)/(c) territory, not this PR.
Residual window, also stated: a push landing between the live read and the PATCH is not caught here.
The run for that push refreshes the table.
