From 21a3e5992ab9a837eba61871886effa26ed77e8f Mon Sep 17 00:00:00 2001 From: Timothy Date: Wed, 2 Sep 2026 19:41:30 +0200 Subject: [PATCH 1/8] fix(869,893): re-establish the 1.25.4-dated CI claims on 1.27.1, and settle the page_statuses asymmetry from source Finishes the claim sweep #747 deliberately left incomplete, and answers #893's open question by reading the v1.27.1 source rather than inferring from a header. Population derived with `git ls-files`, not from #869's item list: 17 files and 43 occurrences of `1.25.4`, materially wider than the four items the issue named. Re-established on 1.27.1 (all previously 1.25.4-dated): - creator attribution (the load-bearing one, since the H10 allow-list rests on it): four merged PR heads, exactly one `.creator.login` row per head and every other row `creator: null`, on BOTH the combined and list endpoints. The mechanism is in the serializer, so the two endpoints cannot disagree. - scope enum: no `status` scope at v1.27.1; nine categories, zero occurrences. - the `reqRepoWriter(unit.TypeCode)` gate on `POST /statuses/{sha}`: unchanged. - the `write:package` 403: re-probed live with a read control (200) and a write control (201), in a throwaway repo, both artifacts deleted and confirmed gone. - the cancel route: absence confirmed in the v1.27.1 router rather than resting on an observed 404, which cannot distinguish absence from a refusal. - `pull_request` vs `pull_request_target` definition resolution: read off `notifier_helper.go`, which is stronger than the four 1.25.4 scratch PRs. Corrected rather than re-dated: - the `--depth=1` no-merge-base claim was filed against the wrong axis. It is a GIT property; a Gitea upgrade cannot change it. Re-probed on git 2.55.0. - `enable_bypass_allowlist` postdating 1.25.4 was sourced from an issue body. Now checked in both trees. It holds; the neighbouring `block_admin_merge_override` does NOT share that history and is present at 1.25.4 too, stated so the paragraph cannot invite the inference. #893: `/statuses/{sha}` does NOT drop rows after pagination. `getCommitStatuses` appends unconditionally and its only filter is a SQL WHERE evaluated in the same query as the LIMIT/OFFSET, so an empty page really is the end. The asymmetry with `count_pr_mutations` is therefore correct and is recorded with its reason. The same two handlers also explain the per-endpoint terminator shapes (`[]` vs bare `null`) that were previously an empirical table. Claims that stay dated now carry a reason that was CHECKED this session rather than inherited: all six workflow triggers re-enumerated, and the direct-push half re-read live. fixes #869 fixes #893 Decisions-Edit: yes Co-Authored-By: Claude Opus 5 (1M context) Claude-Session: https://claude.ai/code/session_01Whe75djeAEuZpdNk6KU7No --- .gitea/workflows/review-verdict.yml | 33 +++++++- docs/ci-cd.md | 18 +++++ .../records/ci/actions-credential-scoping.md | 78 +++++++++++++------ .../ci/batch-pushes-no-cancel-route.md | 26 ++++++- .../records/ci/exemption-provenance.md | 11 ++- .../records/ci/gate-trigger-base-resolved.md | 20 +++++ .../ci/verdict-write-retarget-fence.md | 66 +++++++++++++--- .../release/main-direct-push-disabled.md | 17 +++- docs/decisions/workflow-process.md | 2 +- scripts/pr-changed-files.sh | 8 +- scripts/tests/test_pr_changed_files.py | 10 ++- 11 files changed, 240 insertions(+), 49 deletions(-) diff --git a/.gitea/workflows/review-verdict.yml b/.gitea/workflows/review-verdict.yml index cb70ce633..c089091c5 100644 --- a/.gitea/workflows/review-verdict.yml +++ b/.gitea/workflows/review-verdict.yml @@ -73,6 +73,20 @@ name: Review verdict # ignored: the BASE definition ran and posted `h10=pending`, on both `opened` and `synchronize`, # with `secrets` still available. # +# RE-ESTABLISHED FROM THE v1.27.1 SOURCE, 2026-09-02 (ersatztv#869), so this no longer rests on a +# 1.25.4 stamp — and it is better evidence than the scratch PRs, because it shows the MECHANISM +# rather than one instance of the behaviour.

The container-registry secret `REGISTRY_PASSWORD` is a personal access token scoped `write:package` + `read:repository` — never an account PASSWORD. This matters because Gitea has NO `status` token scope: `POST /repos/{o}/{r}/statuses/{sha}` is gated by `reqRepoWriter(unit.TypeCode)`, so ANY credential that can write the repository can forge `review-verdict/h10`, the required context that is supposed to make merge-consent derived rather than assertable. Package-write IS a separate scope, so the registry credential can be made status-incapable at no cost: `scripts/ci-detect-already-validated.sh` only GETs. `permissions:` on a workflow/job DOES bind on this instance — MEASURED 2026-08-27 on 1.27.1 by matched scratch-base probe PRs differing only in one unit, the block carried at JOB level on `set-verdict-status` (`code: write` posted the probe status; `code: read` 403ed the POST, curl exit 22, no status written), so all six workflows here now declare it (#748). Two properties that make it usable: the declaration is EXHAUSTIVE, not additive — a unit omitted is not granted — and it binds while the owner-level default is `permissive`, which is what makes the five `code: read` declarations effective TODAY rather than only after a flip. NOT established: what a declared `code: write` does under a RESTRICTED default. GitHub semantics let `permissions:` only narrow, never widen past the default, and if Gitea copies that, Restricted would cap the gate job at read and `review-verdict/h10` would stop being writable — the exact catastrophic case. The probe ran under `permissive` and CANNOT rule that out. Flip the owner default only behind the scratch-base probe re-run under Restricted (server-management#714, still open for this reason). The earlier form of this rule said the opposite ("do NOT add a `permissions:` key on the assumption that it binds — below Gitea 1.26.0 it is silently a NO-OP"); that was correct at 1.25.4 and is retained here so a reader meeting the old advice recognises it as superseded. There is still no API surface for the owner-level default (`/api/v1/settings/actions` 404s at 1.27.1). The instance default HAS since been probed and is NOT unknown: it was set to Restricted, verified, and reverted to `permissive` on 2026-08-05 (#748), which is where it stands. Probe before relying on it; do not read the upgrade alone as the constraint now working. Scoping is necessary and not sufficient: it bounds what a job may DO, never whether attacker YAML runs at all, so a self-referencing trigger needs its own filter. That landed for `ci-image.yml` in #744 (`ci.toolchain-image-publish-is-a-dispatch`) — deliberately NOT bundled here, because until it also removed the file from `ci-image-pin`''s `expected`, editing it re-pointed that job at the editing commit and reddened a blocking check. A second, separate consequence of the same boundary: `actions/checkout` persists whatever the job token can do into `.git/config` unless `persist-credentials: false` is set — read-only everywhere since #748 declared `permissions:` on all six workflows — and all 16 of this repo''s checkouts now set it — 15 in #746 and `ci-image.yml`''s in #744, once `ci.toolchain-image-publish-is-a-dispatch` removed the two mechanical reasons it was excluded; the convention is held with no exemption list by `scripts/tests/test_workflow_persist_credentials.py` (#835). Ordering is part of the rule: unmask the dependent fetches FIRST, because until then a credential regression presents as an empty changed-file set and a silently skipped check rather than a red job. This record closes ONE route. It does not close the class, and the later sections say exactly what survives — read them before citing this record as a mitigation. The `workflow_dispatch` half of what survives is now settled rather than open: #853 probed Gitea 1.27.1 and ACCEPTED it (`ci.workflow-dispatch-ref-unrestricted`) — there is no ref restriction and no protected-environment concept to gate a secret behind, and restricting dispatch would close nothing anyway, because `docker-build.yml`''s head-resolved `pull_request:` runs attacker-authored YAML, which reaches EVERY secret in the store and not merely the ones the committed workflows name.

Two independent cold reviews (a fresh Opus agent and a cross-family Codex pass) agreed on the first finding; I re-verified every one against the v1.27.1 source before changing anything. The real defect — the stated MECHANISM for `creator: null` was wrong, and it was labelled "re-derivable", which is the worst combination. It said null means `CreatorID == 0`. It does not: an Actions job authenticates as the synthetic Actions user `ActionsUserID = -2`, `NewCommitStatus` stores `CreatorID = Creator.ID`, so the `if status.CreatorID != 0` branch is TAKEN. The null comes from the next line — `GetUserByID(-2)` is a bare lookup with no system-user mapping (contrast `GetPossibleUserByID`, which handles `id < 0`), it misses, the error is discarded, and `ToUser(ctx, nil, nil)` returns nil. The MEASUREMENT was right; only the explanation was wrong, which is exactly the shape #881 is about. Carries the consequence the wrong version hid: null means "no user row resolved", not "a machine wrote this" — a deleted author is indistinguishable, which is safe here only because the test fires on a POSITIVE allow-list match. Overclaims, each narrowed to what the evidence supports: - "the last load-bearing 1.25.4-dated claim" — false; the fence's `pull_request_target` half is load-bearing and still dated. - the `notifier_helper.go` read discharges DEFINITION RESOLUTION only. It says nothing about event `types` or secrets availability, so those halves stay scratch-PR-attested on 1.25.4. - "no agent-side cancel route" now scoped to the REST surface; `api.go` cannot speak for the web UI or the runner protocol. - "#869 finished the sweep" — it swept and re-established most of it; three findings stay dated by decision. - "two different commits by construction" -> two SEPARATELY RESOLVED refs; nothing forbids them resolving equal. And the one I am least comfortable with, now stated honestly: the reason given for not re-probing MCP `cancel_run` was invented. I wrote "there is no disposable run to spend", which is false — four of six workflows carry `workflow_dispatch:` (renovate's defaults to `dryRun: full`), and the record itself says `dispatch_workflow` still works. It was also self-refuting, since the REST half was probed by observing a 404, which cancels nothing. The true reason is that the agent harness refused the call, and that is what the record now says. Removing that false reason also made two neighbours stale, and both are fixed in the same commit.

The container-registry secret `REGISTRY_PASSWORD` is a personal access token scoped `write:package` + `read:repository` — never an account PASSWORD. This matters because Gitea has NO `status` token scope: `POST /repos/{o}/{r}/statuses/{sha}` is gated by `reqRepoWriter(unit.TypeCode)`, so ANY credential that can write the repository can forge `review-verdict/h10`, the required context that is supposed to make merge-consent derived rather than assertable. Package-write IS a separate scope, so the registry credential can be made status-incapable at no cost: `scripts/ci-detect-already-validated.sh` only GETs. `permissions:` on a workflow/job DOES bind on this instance — MEASURED 2026-08-27 on 1.27.1 by matched scratch-base probe PRs differing only in one unit, the block carried at JOB level on `set-verdict-status` (`code: write` posted the probe status; `code: read` 403ed the POST, curl exit 22, no status written), so all six workflows here now declare it (#748). Two properties that make it usable: the declaration is EXHAUSTIVE, not additive — a unit omitted is not granted — and it binds while the owner-level default is `permissive`, which is what makes the five `code: read` declarations effective TODAY rather than only after a flip. NOT established: what a declared `code: write` does under a RESTRICTED default. GitHub semantics let `permissions:` only narrow, never widen past the default, and if Gitea copies that, Restricted would cap the gate job at read and `review-verdict/h10` would stop being writable — the exact catastrophic case. The probe ran under `permissive` and CANNOT rule that out. Flip the owner default only behind the scratch-base probe re-run under Restricted (server-management#714, still open for this reason). The earlier form of this rule said the opposite ("do NOT add a `permissions:` key on the assumption that it binds — below Gitea 1.26.0 it is silently a NO-OP"); that was correct at 1.25.4 and is retained here so a reader meeting the old advice recognises it as superseded. There is still no API surface for the owner-level default (`/api/v1/settings/actions` 404s at 1.27.1). The instance default HAS since been probed and is NOT unknown: it was set to Restricted, verified, and reverted to `permissive` on 2026-08-05 (#748), which is where it stands. Probe before relying on it; do not read the upgrade alone as the constraint now working. Scoping is necessary and not sufficient: it bounds what a job may DO, never whether attacker YAML runs at all, so a self-referencing trigger needs its own filter. That landed for `ci-image.yml` in #744 (`ci.toolchain-image-publish-is-a-dispatch`) — deliberately NOT bundled here, because until it also removed the file from `ci-image-pin`''s `expected`, editing it re-pointed that job at the editing commit and reddened a blocking check. A second, separate consequence of the same boundary: `actions/checkout` persists whatever the job token can do into `.git/config` unless `persist-credentials: false` is set — read-only everywhere since #748 declared `permissions:` on all six workflows — and all 16 of this repo''s checkouts now set it — 15 in #746 and `ci-image.yml`''s in #744, once `ci.toolchain-image-publish-is-a-dispatch` removed the two mechanical reasons it was excluded; the convention is held with no exemption list by `scripts/tests/test_workflow_persist_credentials.py` (#835). Ordering is part of the rule: unmask the dependent fetches FIRST, because until then a credential regression presents as an empty changed-file set and a silently skipped check rather than a red job. This record closes ONE route. It does not close the class, and the later sections say exactly what survives — read them before citing this record as a mitigation. The `workflow_dispatch` half of what survives is now settled rather than open: #853 probed Gitea 1.27.1 and ACCEPTED it (`ci.workflow-dispatch-ref-unrestricted`) — there is no ref restriction and no protected-environment concept to gate a secret behind, and restricting dispatch would close nothing anyway, because `docker-build.yml`''s head-resolved `pull_request:` runs attacker-authored YAML, which reaches EVERY secret in the store and not merely the ones the committed workflows name.

That review verified the corrected creator-null mechanism step by step against the v1.27.1 source and found it sound, then found seven new defects in the fixes themselves — which is the pattern this repo keeps hitting: each fix round introduces an adjacent one. The instructive one: round 2 replaced an overclaim ("#869 finished the sweep") with a precise list of what remains dated. The list was wrong within the same commit — it named three residuals and omitted three the commit itself created. A second copy of a set is exactly what goes stale, so there is now no list: the reason lives with each finding and `git grep 1.25.4-dated` is the population. Over-retreat, corrected. Round 2 re-dated BOTH halves the notifier_helper read does not cover. Only the secrets half deserved it. That this workflow's `types:` produce pull_request_target runs on 1.27.1 is exercised continuously in production — every PR merged since the upgrade carries this job's context, and runs 2537/2538/2539 are three on the single head sha 3332662c, which one synchronize cannot produce alone. Retreating past what the corpus already measures is its own defect. Also: - the forward reference promising a "checked" reason for both remaining cancel-route findings; the MCP one is session-local and the web-UI one has no reason at all, and it now says so. - a self-refuting argument removed rather than patched: the REST 404 cost nothing BECAUSE the route was absent, which is the proposition under test. The finished-run-id argument that follows it is the one that works. - a wrong internal citation ("two paragraphs up", scoped to re-triggering main). - the round-2 pronoun fix turned "NOT measured with this token" into a false claim: the `container:` pull IS exercised by the shipped credential on every PR. Now says not COVERED BY EITHER PROBE, and that this means unprobed rather than unexercised. - one blanket reason covering three measurements fit only the third; the first two were probe-PR-measured and simply not re-run.

The container-registry secret `REGISTRY_PASSWORD` is a personal access token scoped `write:package` + `read:repository` — never an account PASSWORD. This matters because Gitea has NO `status` token scope: `POST /repos/{o}/{r}/statuses/{sha}` is gated by `reqRepoWriter(unit.TypeCode)`, so ANY credential that can write the repository can forge `review-verdict/h10`, the required context that is supposed to make merge-consent derived rather than assertable. Package-write IS a separate scope, so the registry credential can be made status-incapable at no cost: `scripts/ci-detect-already-validated.sh` only GETs. `permissions:` on a workflow/job DOES bind on this instance — MEASURED 2026-08-27 on 1.27.1 by matched scratch-base probe PRs differing only in one unit, the block carried at JOB level on `set-verdict-status` (`code: write` posted the probe status; `code: read` 403ed the POST, curl exit 22, no status written), so all six workflows here now declare it (#748). Two properties that make it usable: the declaration is EXHAUSTIVE, not additive — a unit omitted is not granted — and it binds while the owner-level default is `permissive`, which is what makes the five `code: read` declarations effective TODAY rather than only after a flip. NOT established: what a declared `code: write` does under a RESTRICTED default. GitHub semantics let `permissions:` only narrow, never widen past the default, and if Gitea copies that, Restricted would cap the gate job at read and `review-verdict/h10` would stop being writable — the exact catastrophic case. The probe ran under `permissive` and CANNOT rule that out. Flip the owner default only behind the scratch-base probe re-run under Restricted (server-management#714, still open for this reason). The earlier form of this rule said the opposite ("do NOT add a `permissions:` key on the assumption that it binds — below Gitea 1.26.0 it is silently a NO-OP"); that was correct at 1.25.4 and is retained here so a reader meeting the old advice recognises it as superseded. There is still no API surface for the owner-level default (`/api/v1/settings/actions` 404s at 1.27.1). The instance default HAS since been probed and is NOT unknown: it was set to Restricted, verified, and reverted to `permissive` on 2026-08-05 (#748), which is where it stands. Probe before relying on it; do not read the upgrade alone as the constraint now working. Scoping is necessary and not sufficient: it bounds what a job may DO, never whether attacker YAML runs at all, so a self-referencing trigger needs its own filter. That landed for `ci-image.yml` in #744 (`ci.toolchain-image-publish-is-a-dispatch`) — deliberately NOT bundled here, because until it also removed the file from `ci-image-pin`''s `expected`, editing it re-pointed that job at the editing commit and reddened a blocking check. A second, separate consequence of the same boundary: `actions/checkout` persists whatever the job token can do into `.git/config` unless `persist-credentials: false` is set — read-only everywhere since #748 declared `permissions:` on all six workflows — and all 16 of this repo''s checkouts now set it — 15 in #746 and `ci-image.yml`''s in #744, once `ci.toolchain-image-publish-is-a-dispatch` removed the two mechanical reasons it was excluded; the convention is held with no exemption list by `scripts/tests/test_workflow_persist_credentials.py` (#835). Ordering is part of the rule: unmask the dependent fetches FIRST, because until then a credential regression presents as an empty changed-file set and a silently skipped check rather than a red job. This record closes ONE route. It does not close the class, and the later sections say exactly what survives — read them before citing this record as a mitigation. The `workflow_dispatch` half of what survives is now settled rather than open: #853 probed Gitea 1.27.1 and ACCEPTED it (`ci.workflow-dispatch-ref-unrestricted`) — there is no ref restriction and no protected-environment concept to gate a secret behind, and restricting dispatch would close nothing anyway, because `docker-build.yml`''s head-resolved `pull_request:` runs attacker-authored YAML, which reaches EVERY secret in the store and not merely the ones the committed workflows name.

Three cold review rounds each found real defects, and nearly every one sat in the same narrow place: prose tracking how complete the sweep is and which residuals remain. The technical core — the source reads, the live probes, #893's answer — came back clean from every reviewer. So this removes the mechanism rather than fixing its latest output, which is what this repo's own precedent says to do once a construct has been patched three times. Two HIGH findings, both self-inflicted by round 3, both verified before acting: - The `git grep 1.25.4-dated` pointer UNDER-reported, which is the unsafe direction, and the commit that added it claimed it "cannot hide a residual". Round 3 had introduced a second spelling, `1.25.4-attested`, in the same commit; the grep matched none of its four instances. Measured: 16 hits for the first term, 0 of the 4 for the second. - "every PR merged since the upgrade carries this job's context" is false, and refuted by a counterexample the same record already documents: PR #863 merged carrying no review-verdict context at all, because a PR into a scratch base does not match `branches: [main]`. So: no list, no derived pointer, no second vocabulary. Both attempts at tracking the residual set failed inside the commit that wrote them, which is the argument against keeping a copy of a set at all. Each residual states its reason where it lives — the copy that cannot drift from its subject. The per-type evidence is replaced with what was actually measured and nothing wider: pull_request_target fires continuously on 1.27.1 (258 runs across 233 distinct head shas), which establishes neither WHICH types fire nor whether the stored secret store is reachable. Both of those stay dated. That also removes a false binding — runs 2537/2538/2539 were cited as merged PRs and belong to PR #761, which is open — and a colon that read as introducing the opposite arm.

The technical core came back verified clean — every source quote, every live measurement, and the whole #893 asymmetry argument. Three residual findings, all in the evidence I added in round 4. The substantive one: the sentence is headed "What IS established on 1.27.1" and cited 258 runs / 233 head shas, which is the ALL-TIME count. Measured independently before changing anything: 258 splits 44 before the upgrade date + 4 on it + 210 after. So 17% of the evidence came from the exact version the paragraph exists to distinguish itself from. Now 210 runs / 189 distinct head shas, strictly after 2026-08-05, with the split spelled out so the arithmetic checks — an earlier draft of this fix said "44 excluded" while excluding 48. The 4 upgrade-day runs are excluded rather than assigned. The upgrade landed mid-session and their 17:41-22:36 start times cannot be placed either side of it without the exact upgrade time, so they go to the side that weakens the claim. Scoping also resolves a "fires here" ambiguity for free: all 8 non-review-verdict runs in the all-time set are pre-upgrade probe workflows, so every one of the 210 is this file, under either reading of "here". And a "two paragraphs down" pointer that was three paragraphs down — the same class as a round-2 finding, so it is now cited by CONTENT instead. A positional reference breaks whenever anything is inserted above it, which is precisely what kept happening.

The record said the difference between the repo-wide all-time figure and this workflow's own was "three since-deleted probe workflows". 258 - 250 = 8, and 8 appeared nowhere in that file — so a reader checking the arithmetic finds a mismatch and goes off to "correct" a number that is already right. The residual is 8 runs from 3 workflows; both copies now say so, and they agree. And "+02:00 / the host is UTC+2" is DST-scoped. The same API payload renders `+01:00` for winter-dated fields, so a reader checking in January sees a doc that contradicts what is on screen.
