The waiting comment opened with a siren and spent four paragraphs explaining itself. A breaking change is often deliberate, and a comment that shouts teaches people to scroll past it — which is the one thing a gate cannot afford. Now: what was found, a link straight to the decision, and who can make it. Everything else — the scope rule, the acknowledgement state, how to undo the break — is one small line at the bottom. Eighteen lines down to nine. Four things are links now where there were none: the offending commit, the pending deployment, the reviewers, and the docs. "Who can approve this" was the obvious next question and the answer was buried in Environment settings nobody thinks to open. Reviewers render as links, never as @mentions: the pending deployment already notifies exactly those people.
Addresses the CodeRabbit review on #907. environment-protection now reads back who the Environment is actually gated by and exposes it, and the reporter prefers that over the configured list. The two differ whenever the Environment already existed or was edited since — and naming the wrong approvers is worse than naming none, which is what the comment does when neither is available. Also from the review: the `reviewers` description still said "rendered as GitHub mentions", written before the switch to links and never updated the README gave `docs-url` as "the gate's docs page" where .coderabbit.yml asks for input tables to match action.yml exactly the example's links all pointed at `(#)` the no-bare-mention test asserted one forbidden spelling, so it passed by accident and would keep passing if the mention were written any other way. It now checks that every `@${owner}/` sits inside Markdown link text — verified by injecting a bare mention and watching it fail
… unknown Addresses the second CodeRabbit review on #907. The composite read the Environment twice: once for the protection rules, once for the reviewers, with the second call swallowing failure. That allowed a state of "protected, reviewers unknown" — and an empty reviewer list is indistinguishable from "this Environment has none", so the reporter fell back to the configured list and could name people who cannot actually approve. Which is the very thing the previous commit set out to fix. The suggestion was to carry the read failure as a distinct status. Removing the state is better than reporting it: one GET now answers both questions, so either both are known or the step fails. It also drops a call to an API this job already talks to twice. Test pins it to exactly one read.
Three things, from reviewing the comment on #906 in place. The call to action is now a shields.io badge wrapped in the link, which is the only thing in Markdown that reads as a button. That puts a third party in the path of a release control, so the alt text carries the whole call to action: a blocked image leaves a described link, not a broken rectangle. Setting badge-url to empty drops the dependency and falls back to a heading link. The "not intentional?" example now shows this pull request's own commit subjects in a diff block instead of a made-up feat(scope)!: subject. It matches only the `!` form, because that is the form the example illustrates — a view, never a verdict. The canonical rule stays in the detector, and with nothing matched the wording goes generic. And only one approval request stays open. Every push queued another pending deployment while the old ones kept sitting in the reviewers' queue, each tied to a commit that is no longer the head — #906 had two at once. Approving one of those approves a revision nobody is merging. A concurrency group keyed to the pull request cancels the previous request, which is also what expires an approval: the yes was given to a specific revision and the next one has to earn its own. The cancelled run still reaches the verdict, so it now checks whether it still covers the head and leaves the pull request alone when it does not. Otherwise it would overwrite the live comment with "the approval did not complete".
The alert block said what happened in prose, which meant reading it to know. A 💥 in an `##` heading inside the block makes the state legible from the timeline, before anyone opens anything — and the table gains marks on the three rows that matter, so it can be scanned instead of read. Each state now gets the alert that fits it: IMPORTANT while a decision is pending, NOTE once approved, CAUTION on a rejection that closed the pull request, WARNING when the decision was never recorded. Colour and icon come from GitHub; the emoji says what the block is about.
Addresses the CodeRabbit review on #909. The state assertions searched the whole reporter script, so every alert and heading was present somewhere no matter which branch used it. Swapping two states' alerts would have kept the suite green while every comment said the wrong thing. The suggested fix pulled each `case` branch out with a regex anchored to the exact indentation. That trades one fragility for another — any reindentation breaks the pattern and the test reports a problem that is not there — and it still reads the source rather than the output. So the tests now run the composite and read the Markdown it produced. `render_reporter(state)` executes the body with `gh` stubbed, and each state is checked for its own alert and mark *and* for the absence of the other three; exclusivity is what catches a swap. Verified by swapping IMPORTANT for NOTE on `waiting` and watching it fail. The link assertions moved the same way: they matched shell fragments like `${SERVER_URL}/${REPO}/commit/...` and now match rendered URLs, so the no-bare-mention rule holds however the composite spells it.
Addresses the third CodeRabbit review on #909. The state test read the rendered comment but checked `[!IMPORTANT]` and `## 💥 …` as separate strings. A GitHub alert only renders inside a blockquote, so dropping the `>` would leave both assertions green while the comment rendered as plain text — getting the content right and the presentation wrong, which is the thing this PR is about. Now asserted as adjacent quoted lines. Verified by removing the `>` from `waiting` and watching it fail.
…fails PR Size, Auto Labels and PR Metadata were gated on `needs.blocking-checks.result == 'success'`, so a wrong title or a missing signature took them down too — the summary reported three `skipped` rows next to the failure. That came from the 2-tier fail-fast model and saved a runner at the expense of the pull request that most needed the help. None of the three can block a merge, all three are cheap, and a pull request already in trouble is exactly where a size label and an assignee are worth having. `needs:` stays for ordering; the verdict is no longer consulted. Drafts and non-pull_request events still skip, as before. Safe because none of the three can fail the job — each is continue-on-error — and the summary and report jobs already run with always(), so an advisory checkout failure still gets reported. Tests pin all three facts.
…rwise Addresses the CodeRabbit review on #911. The new section described advisory checks running regardless of the blocking result while two other places in the same file still described the old behaviour — the Jobs table and the Tier 2 bullet. Contradictory documentation is worse than none: whoever reads the table believes it. A third one was not flagged and was wrong too: the Tier 1 bullet said a blocking failure prevents advisory checks from running. Also fixes the test that was supposed to make this change safe. It asserted over the whole job text, so a step — or the comment above the assertion, which contains the word always() — satisfied it while the job-level needs and if said something else. It now reads the parsed job. Verified by dropping advisory-checks from a needs list and watching it fail.
Caught on #906. Editing the pull request description fires `edited`, which queues a new run on the very same commit. The concurrency group cancelled the previous pending approval, correctly — but the superseded guard only compared head SHAs, and the head had not moved. So the dead run fell through to "decision not recorded", overwrote the live revision's comment and failed its check, while the new run sat waiting with the real request. A cancelled approval now counts as superseded on its own, and is checked first because it is the broader signal: nothing cancels it except the concurrency group replacing the run or a human doing it by hand, and neither is a decision worth reporting. The head comparison stays for whatever slips past that. Test pins both the new branch and its order ahead of the comparison.
Addresses the CodeRabbit review on #912. The cancellation test checked the branch and its ordering but not its `exit 0`. Without that exit a cancelled run falls through, and a recorded rejection downstream wins: the verdict comes back `rejected` and the pull request is closed — because a concurrency cancellation raced a reviewer. Closing a pull request by accident is the most destructive thing this workflow does, so "trivial" undersells it. Asserting the characters `exit 0` are present would prove nothing about whether the branch stops, and would be the fifth text assertion in this series. `run_verdict()` executes the step with `gh` stubbed instead, and the test hands it a rejection to fall through onto. Removing the exit makes it fail with 'superseded' != 'rejected' — which is how the report was confirmed in the first place. Also covers the whole state table by running it: approved, rejected, superseded from a cancellation, superseded from a moved head, unresolved, none, blocked. Those cases existed only in a scratch harness before.
The breaking change guard comment has never been posted. Every run
since 2026-08-06 took a 403 and reported success:
RequestError [HttpError]: Resource not accessible by integration
POST /repos/{owner}/{repo}/issues/{n}/comments
The job declared `pull-requests: read` with `issues: write`. The step
posts through the issue-comments endpoint, but the subject is a pull
request, and GitHub authorises those as pull requests — `issues: write`
covers real issues only. A job-level block replaces the workflow's
rather than merging with it, so declaring `read` there was not least
privilege; it was below what the step needs to do anything.
The cost was not cosmetic. An author who omits the acknowledgement line
sees Blocking Checks fail with no explanation, because the comment that
would explain it is the one that never arrives.
Two months of silence were possible for two reasons, both addressed:
the step is continue-on-error, so the 403 never surfaced. It stays —
losing a comment should not fail validation — but a failed post now
emits a ::warning:: instead of vanishing
a test pinned the permission set to exactly {pull-requests: read,
issues: write}. It did not merely miss the bug, it held it in place.
Swept the other workflows for the same shape: frontend-pr-analysis and
go-pr-coverage-comment both comment on pull requests and both inherit
`pull-requests: write` from their workflow level, so they are fine. A
test now covers every job that comments, so the next one cannot repeat
this.
CodeRabbit only runs once every check has passed, and that now includes the approval gate. So each round of approve → review → fix → push needed a fresh human approval before the next review could happen — and the reviewer was answering the identical question about an unchanged breaking change. A question asked five times gets a reflex answer by the third. The gate asks about a specific breaking change, so it now remembers which one was approved. New composite breaking-change-commits lists the commits carrying the break and digests their SHAs; the approval comment records that digest, and a later run with the same digest skips the Environment entirely. typo fix, ordinary commit approval stands reworded breaking commit asks again another breaking commit asks again Built from SHAs, so a reword counts: the approval was given to the text that was read, and the subject is what the release parser acts on. The records accumulate in the comment and are carried across rewrites — every run rebuilds the body, so without that the approval would be forgotten by the very next push. The composite also replaces the partial copy of the rule that lived in the reporter, which only matched the `!` form. Its tests cover the same negative cases as the detector: `BREAKING-CHANGE` with a hyphen and prose mentioning the phrase are not breaking.
Lists the commits in a pull request that carry a breaking change, and digests their SHAs so an approval can be matched against what it approved. Landed on its own, consumed by nothing yet. A composite cannot be used at @develop by the pull request that introduces it, and now that the approval gate is a required check that is no longer a cosmetic problem: the pull request adding the composite would be blocked by the gate that cannot resolve it. Two pull requests, the same way breaking-change-guard was introduced. The patterns match the detector exactly, including what must NOT count: BREAKING-CHANGE with a hyphen, and prose mentioning the phrase mid-line. Those are the cases where a view that disagreed with the verdict would be most confusing.
Addresses the CodeRabbit review on #915. The first one is a gate bypass. Commit subjects are written to GITHUB_OUTPUT as a multiline value with a fixed delimiter, and whoever opens the pull request writes them. A commit whose subject IS that delimiter closes the block, and every line after it becomes an output assignment — including `fingerprint=`, which decides whether a breaking change counts as already approved. Two commits are enough to skip the approval entirely: subject: BREAKING_SUBJECTS_EOF + a BREAKING CHANGE footer subject: fingerprint=<approved one> + a BREAKING CHANGE footer The delimiter is now random per run and checked against the subjects before anything is written. The suite runs that attack, and the check is parsed the way the runner parses it — lines inside the block are a value, so grepping the raw text would have called a harmless line a breach. The patterns also did not match the detector, despite the header saying they did: [[:space:]\|\*] — a backslash inside a bracket expression is a literal backslash, so the class quietly accepted a leading `\` \([^)]*\) for the scope where the detector has \(.*\), so a scope containing a closing paren was breaking there and ordinary here Both now transcribe the detector exactly, held in variables so a bare `|` is not parsed as an operator. Six cases cover the forms where a slip shows: lowercase, mixed case, plural, space separator, uppercase subject, and a scope with a paren in it. And a resolver failure now reports `not ok` instead of aborting the suite at the assignment, where `set -e` took the summary with it.
#915 landed the composite, including the fix for the output injection found in its review: a commit subject could close the multiline block and forge `fingerprint=`, which is the value this branch reads to decide whether a breaking change was already approved. This branch still carried the pre-review copy of those files, so the conflicts are resolved in favour of develop — taking the random delimiter and the patterns transcribed from the detector. Had they resolved the other way, this pull request would have reintroduced a way to skip the approval by writing a commit message. The composite is now byte-identical to develop; what remains here is the wiring that consumes it.
Addresses the CodeRabbit review on #914. The first finding is a gate bypass, and the documentation I wrote got the threat model wrong. The lookup accepted the fingerprint marker from any comment on the pull request. Anyone with read access can comment, and the fingerprint is computable from public data — the commit SHAs are on the pull request and the digest is defined in this repository. So a stranger could paste a marker and skip the Environment entirely. The docs claimed forging "means editing a bot's comment, which needs maintainer rights". Nothing had to be edited; creating a comment was enough. Two independent conditions now hold before an approval is reused: the record sits in a comment from an OWNER or MEMBER the run it names really was approved for the Environment, read from the Environment's own approval log The second carries the weight. Writing the text is easy; producing a run whose approval actually happened is not. Verification needs `actions: read`; without it the approval is not reused and the reviewer is asked again — asking twice costs attention, trusting an unverified record costs the gate. Three more from the same review: `grep -qF` could exit on the first match while `--paginate` was still writing, and under pipefail the broken pipe read as "no match" — so an approval already given was asked for again. A second `grep -q` had the same hazard and was not flagged; both are gone. the reused-approval branch sat ahead of the cancelled, superseded and request-result guards, so a run whose preflight had failed reported success. A standing approval is not a reason to skip the checks that say whether this run may speak at all. a failed comment read turned into "there were no records", and the rewrite that followed erased every approval on the pull request. It now fails instead of rewriting blind.
Three from the second CodeRabbit review on #914. The author filter dropped `github-actions[bot]`, for which GitHub can report `author_association: NONE`. That is the identity the reporter writes under whenever no MANAGE_TOKEN is passed — most callers — so the filter I added to close the forgery hole quietly disabled the feature for them. Accepted by exact login now: nobody but Actions can author under it, so it costs nothing. Only the first record was checked. Runs are deleted on the repository's retention schedule, so the oldest record for a fingerprint goes unverifiable first while a newer one is still good — and the lookup would ask for an approval that was on file. Every record is tried now. And a reused approval was writing a record naming the current run, whose Environment approval never happened. That record asserts what no log can confirm, and accumulates with each reuse until the only records left are the unverifiable ones. A record is written only when `needs.approval` actually succeeded.
The author filter grew a third clause, so the closing paren moved to the next line and `test_a_forged_approval_record_is_not_believed` stopped matching. I pushed that commit without rerunning the suite — the test guarding the forgery fix was red on the branch. Also drops a comment left describing a `grep -F ... >/dev/null` that no longer exists; the code captures output instead. A stale comment about a hazard is worse than none, because the next reader checks the comment rather than the code.
…tract From the CodeRabbit review on #914. The repository's rule is that a real run stays silent beyond one summary line, and this step printed a notice per unverifiable record on top of its verdict. The other half of that rule was broken too, and was not flagged: the step carried `&& !inputs.dry_run`, so it never ran under dry_run at all. A preview that cannot say whether the approval would be reused is not previewing the decision this gate turns on. It only reads, so it now runs either way. Real run: one `::notice::` when an approval is reused, one `::warning::` when records exist but none verify — naming the runs it tried, which is the thing someone debugging needs — and nothing when there is no record. Dry run: the fingerprint, how many records were found, which runs failed to verify, and the resulting decision.
…_run rule From the CodeRabbit review on #913, which flagged the ::warning:: this PR adds as a breach of "dry_run: false must be silent". Keeping the warning: the rule's own wording is "let failures surface via exit codes", and a continue-on-error step has deliberately given that channel up. With no exit code and no annotation a failure is invisible — which is precisely how the 403 this PR fixes ran for two months with every job green. Twenty-two steps already in this repository annotate failures on a real run, so the practice predates the question. What the review did expose is that the rule never says any of this. It does now, with the case that proves it.
`typos` finds `Hed` inside `PATCHed` and exits 2, failing Spelling Check. The word is accurate but not worth an ignore entry.
…t a major The owner's call, and the evidence supports it. The gate shipped in v1.84.0 four days ago, and none of the three umbrellas expose an input for `label` — only `force_labels` and `skip_labels`. The only configuration that could notice the label now surviving a decision is a standalone caller that set a custom one inside that window. So: documented, not versioned. The page says what changed, what the earlier reading was and how to get it back, and says plainly that it is not classified as breaking and why. An unannounced behaviour change is worse than a documented one whatever the number says — the defect Radagast caught was the silence, not the version. Also fixes the inputs table, which still promised `label` was 'applied while waiting, removed once resolved' two sections below the paragraph saying the opposite, and never listed `pending_label` at all.
5 of 13 tasks
…ason CodeRabbit on #937: the paragraph justified both changes with one argument, and that argument only covers the `label` input. Fair — a caller branching on an output does not have to set a label to notice a change in it. Its premise about who is affected does not hold, though. The umbrellas do not surface the gate's `has_breaking_changes`: theirs comes from the `breaking-change-guard` job, which is unchanged, and the only gate outputs they publish are `breaking_change_approval_result` and `breaking_change_approved_by_reviewer`. So the affected set is the same — standalone callers — for a different reason. Both reasons are now stated separately, each covering what it actually covers. Same correction in the test comment.

The executed 104-test suite plus a call-site scan WOULD validate the smaller helper.

src/notify/breaking-change-approval-reporter/action.yml:132: Adding blocked as a reporter state now routes unknown detection through the unconditional fact-label block. With no established breaking commit, a transient detection failure adds breaking-change to a potentially clean PR; the actual blocked reporter probe recorded add-label breaking-change. The comment correctly says the result is unknown, but the label asserts the opposite. Avoid adding the fact label for unknown detection; retain existing labels until detection establishes the fact, or pass the known detection result separately. A blocked/unknown reporter test asserting no fact-label addition, alongside known-breaking cases, WOULD prove the correction. This is distinct from the overridden out-of-scope label-removal thread.

.github/workflows/breaking-change-approval.yml:543-547: Serialize all historical approvers as one valid output value. The approvals API returns a history array, and the jq expression emits one login per matching approval. With two matching entries, the actual prior script writes approved-by=alice followed by a bare bob line. GitHub runner output-file parsing rejects that line, failing request before a fresh approval can be requested. The outcome then becomes blocked/failure even for an unchanged, previously approved breaking set; subsequent pushes selecting the same record repeat the failure. This breaks the advertised approval-reuse contract, rather than merely losing display attribution. Join the logins into the comma-separated representation the reporter expects. An executed lookup regression with multiple history entries and runner-equivalent output validation WOULD prove the fix; the current source-order assertions do not exercise serialization.

Block C of @radagast-lerian's review on #926 — the four non-blocking findings left. **`subjects` had no consumer.** The detect job exposed it and nothing read it, while the reporter listed the same commits again off its own API call. Two readings of one pull request that can disagree, for an extra call per run. Taking his second option rather than deleting the output: the gate forwards it, the reporter prefers a supplied set, and an empty one still reads the commits — so a standalone caller needs no resolver. The defang applies on both paths. **Nothing retired the comment this one replaced.** `breaking-change-comment` owned `<!-- lerian-breaking-change-guard -->` and cleaned it up; removing that job removed the cleanup, so a pull request opened before the changeover keeps an 'awaiting acknowledgement' notice forever, beside this comment and contradicting it. Restored narrowly: only a bot comment the marker opens, never the approval records, and marked transitional. **The cap documentation prescribed a split to callers who do not need one.** True of standalone detection only. With detection supplied the answer stands and the gate is not blocked — what is lost is the fingerprint, so a fresh decision is asked for. Both cases now stated. **`run_detect_normalization` carried its own copy of `execute_body`.** It keeps the step selection and the defaults and delegates the execution. Also: `run_reporter_labels` could not see `set -u` firing inside a command substitution — the subshell dies, the script carries on, and the exit code stays 0, so a fixture missing a variable read as 'the step made no calls'. Found by hitting it. It now fails on 'unbound variable' in stderr.

@radagast-lerian on #926, over the head carrying Block A. The blocking one is mine, introduced there. **Two approvers broke the reuse contract.** The approvals API returns one login per line and an Environment can require more than one reviewer. Written straight to GITHUB_OUTPUT the second lands on its own line with no `=`; the runner rejects it and the step fails. That is not a lost display name - `request` fails, the verdict reads `blocked`, and a breaking set that was already approved is blocked again on every push. Reproduced by writing the file and reading it back the way the runner does. Now joined with commas, which is what the reporter already parses. **`blocked` asserted things it had not established.** Three ways: - It always blamed detection, but `blocked` is also reached with detection successful and the request stage failing - an Environment preflight refusing an unprotected `breaking-approval`. The wording is now neutral and points at the run rather than at a stage. - It applied the fact label. Nothing was established, so a transient detection failure would brand a pull request carrying no break at all. Labels already there stay; removing them is the same mistake inverted. - It asked for an acknowledgement nobody had evaluated. Normalization sent `false` where it means "not looked at" - it now sends empty, as the local-count branch already did, and the follow-up is a no-op on empty. **Two internal interfaces with no reader**, both added by me: the `approving-run` job output, and `expect_failure` on `run_verdict` - whose assertion is now unconditional. Also documents `enable_approval` in the workflow guide and `blocked` in the reporter's state contract and README, where the list still said any other value fails.

@radagast-lerian — all seven non-blocking findings addressedThe blocking one is answered in its thread. These five Medium and two Low had no inline thread, so they are answered here. All are merged to All five Medium were mine, introduced while fixing the earlier findings. Every one was reproduced before being changed.

Not blocking (1)
- 🟡 Medium · Keep legacy-comment cleanup failures from blocking approval ·
src/notify/breaking-change-approval-reporter/action.yml:468: The new legacy-comment listing is an unguarded pipeline under set -euo pipefail; only individual DELETE failures are tolerated. If the normal comment lookup/read succeeds but this second listing fails, the reporter exits before PATCH/create and suppresses the API error. Executing the complete reporter with that fixture produced "legacy-fail: exit=1 PATCH=False stderr=''", versus exit=0/PATCH=True with a successful listing. The waiting reporter is not continue-on-error, so request fails, approval is skipped, and the verdict becomes blocked/failure. An outcome-reporting invocation can also lose its newly generated approval record. This adds a failure point to an already fail-hard reporting path, not a fail-open bypass. Make transitional cleanup best-effort with a warning, retaining strict handling of the approval-record read. A regression failing only the legacy listing while requiring PATCH/create and successful reporting WOULD prove the author's fix. Reusing the existing comments listing can also avoid the second pagination.
Low and nits (3)
- 🔵 Low · Execute the deletion filter against comment fixtures ·
src/validate/breaking-change-guard/test-workflow.py:1863: The retirement test supplies preselected legacy_ids to its gh stub and checks the production predicate only as source text. It therefore proves that supplied IDs are deleted, not that human comments, quoted markers, or approval-history comments are excluded. An in-memory mutation broadening both jq predicates while retaining the checked strings in comments still yielded "retirement_test_passes=True". No checkout mutation was made. Replace the string assertions with execution of the real --jq query over positive and negative comment fixtures, then assert the exact DELETE IDs and successful completion. That regression WOULD detect a widened selection; this is ordinary coverage, not an established data-loss vulnerability. This consolidates report L1/D1 rather than treating removal of the assertions alone as a fix. - 🔵 Low · Document the blocked-state behavior of both labels consistently ·
src/notify/breaking-change-approval-reporter/README.md:27: The new blocked row says that labels already present are left alone, but the reporter removes a configured pending label in that state. The existing Two labels section also still promises that the fact label is applied in every state, contradicting the new blocked exception. Executing blocked produced only "remove-label awaiting-breaking-approval". Clarify that an existing fact label is preserved, the fact label is not newly applied, and the pending label is removed; update the all-state statement too. Comparing that documentation with the existing executed blocked-state label test WOULD validate the correction. - ⚪ Nit · Update the commit-list suite count to 22 ·
src/validate/breaking-change-commits/README.md:132: The local-test description says 20 cases, but the suite at this head reports "22 passed, 0 failed", including its two enumeration-count cases. Update the count to match the suite. This is documentation only and outside the incremental code changes; it does not affect approval behavior.

Closing this release PR: the shared-workflows release goes back to @bedatty, who owns the breaking-change approval workflows (fredcamaral, 2026-10-20). Nothing is lost: the head is State at close, for whoever opens the next one:

@fredcamaral both findings are fixed on Critical, approval reuse. You were right that the branch check establishes an approval and nothing about what it covered. The record now says only which run to ask, and the run answers:
Your forged case is the test: Three ways to not reuse, all of which ask the reviewer again: no verified record, an unresolvable approved set, or a set that differs. The 250 cap applies to the comparison too, against High, cancellation as supersession. Fixed, and the Your two unchecked items are still unchecked, and worth a follow-up:
The fix does not depend on the second — the record's author no longer determines what gets reused, only which run is consulted — but it would still widen who can get a record read, and that is worth knowing rather than assuming. One thing your report changed beyond the two fixes. Both of these, and most of what @radagast-lerian found before them, survived assertions that read the source instead of running it. Everything added here executes the step and reads what it did, and the two attacks were verified by mutation rather than by passing. #936 wired in three composite suites that no workflow was running at all — 76 cases, including the output-forgery ones. #926 is closed; the release will be reopened from |

Description
Release
developtomain. It ships, in order of landing:RADAGAST_AUTHORS(todayfredcamaral), and its notice says the PR is reviewed by Radagast. Inputs and defaults are unchanged; an unset or empty variable behaves exactly as before, so nothing changes outside LerianStudio.The release opens the promotion train:
tier-0promotes on its own;tier-1andtier-2wait for the environment approval (G_Github_Devops). Oncetier-2is promoted, adding or removing a Radagast author is only an edit to the org variable.Type of Change

None — but two behaviours of
breaking-change-approval.ymldid change after its first release, and they are written down rather than left silent. @radagast-lerian was right that the earlier "None." hid them; the version classification is a separate question and the measurement answers it.1.
labelsurvives the decision. It used to come off on approval. It is a fact about the change — approving a break does not make it stop being one — so it is now removed only when the breaking commits are gone. The transient marker moved to the newpending_labelinput (awaiting-breaking-approval), which does come off once approved or rejected.2.
has_breaking_changesreports detection out of scope. It used to be forced tofalsewhenever the gate did not apply, conflating "not gated here" with "carries no break". It now passes through what the caller detected. For the earlier reading, gate onin_scopealongside it.Why this is not classified as breaking: the gate shipped in
v1.84.0on 2026-10-15, four days ago, and none of the three umbrellas (pr-validation,go-pr-validation,js-pr-validation) expose an input forlabel— onlyforce_labelsandskip_labels. A caller on the normal path could not have configured a custom label to begin with; only a standalone caller inside that four-day window could notice. No internal caller readshas_breaking_changesto act on it.Documented in
docs/breaking-change-approval.md→ Behaviour changes since v1.84, with the before/after for both.Testing
Each change was validated in its own PR into
develop(see the PRs above). #925:tests/coderabbit-gate/test-workflow.shruns the gate step against a stubgh(2 of 5 cases failed before the change, 5 of 5 pass after), wired into self-PR-validation; actionlint, shellcheck and yamllint report 0 errors; a local dry run printed the variable and the Radagast notice.The approval gate carries 104 workflow tests plus four composite suites (60 detector, 32 gate-scope, 22 commit-list, 22 CODEOWNERS) — the last three were not invoked by any workflow until #936 and now run in self CI. It was exercised end to end on real pull requests: rejection closing the PR (#921), approval surviving later commits (#922/#923), and a clean PR passing untouched (#924).
