Scot Breitenfeld 46323c29b8 review-checklist: ping assignee(s) and label PRs once fully signed off (#6672)
* review-checklist: ping GitHub assignee(s) once the checklist is fully signed off

Adds computeAssigneePing(), a pure function that posts a ready-to-merge
comment mentioning the PR's assignees the moment every CODEOWNERS area
transitions from pending to signed-off. Gated on the false->true
transition so it fires once, not on every later workflow run while the
PR stays fully approved, and posted as its own comment since editing
an existing comment to add a mention isn't a reliable notification.

* review-checklist: sync a checklist-complete label with the all-done state

Toggles the "checklist-complete" label (pre-created in the repo, green
#0E8A16) on and off to track whether every CODEOWNERS area is currently
signed off, so it's visible as a badge on the /pulls list without
opening each PR. Unlike the assignee ping, this is level-triggered: the
label comes off again if a later change request breaks the sign-off,
and reattaches once the PR is fully approved again.

Scot Breitenfeld 31d9d3c322 Fix release-progress badges to read native issue-level Priority field (#6668)
* Fix release-progress badges to read native issue-level Priority field

The Project Priority board field was consolidated into a Priority field
managed at the issue level (GitHub's org-wide custom issue fields), which
the GraphQL API mirrors into projects as ProjectV2ItemIssueFieldValue
instead of ProjectV2ItemFieldSingleSelectValue. The badge script's query
had no fragment for that type, so it silently found zero priority values
and would raise ProjectFieldMissingError on every run.

* Show TBD on the Next Release badge when no milestone due date is set

Previously the badge silently omitted any due-date annotation when the
milestone had none, which read as if the badge just hadn't picked one up.

* Update release-schedule image and plantuml source from add-next-release-badge branch

* Don't flag CODEOWNERS auto-assignment as a manual reviewer add on a PR's first pass

GitHub's own CODEOWNERS engine fires an identical review_requested webhook
(sender type User, not Bot) when it auto-assigns owners at PR-open time. If
one of those survives the cancel-in-progress race as the run that actually
executes, it was mistaken for a human deliberately requesting that reviewer,
permanently flagging them "manually added" and requiring separate approval —
e.g. a catch-all "*" owner also named on a touched area's CODEOWNERS line got
flagged on every PR touching that area, even though no human ever picked them.

Gate the manual-add detection and the sticky per-area assignment on
!isFirstCoordinationPass (no checklist comment posted yet), since that's
exactly the window where GitHub's own auto-assignment is indistinguishable
from a real human pick.

Scot Breitenfeld 9515219a32 Review automation: fix comment-only reviewer drop and draft-stale thrash (#6658)
* review-checklist: don't lose a reviewer who only left comments

GitHub un-requests a reviewer the instant they submit any review,
including a comment-only one from batching several inline comments into
a single submission — not just Approve/Request-changes. Unlike a stale
approval, this never produces a DISMISSED transition, so the checklist
had no way to tell "abandoned the area" apart from "still reviewing,
just hasn't finished yet."

This silently dropped the reviewer's mention from the checklist display
the moment they left comments, and risked the next push's additive-fill
picker handing their area to a completely different load-balanced
reviewer (observed on PR #6645: jhendersonHDF's batched review comments
repeatedly vanished him from src/test's rows mid-review).

Track a sticky area assignee as still engaged whenever they have no
APPROVED/CHANGES_REQUESTED/DISMISSED review on record, regardless of
whether GitHub currently lists them as requested, and use that in the
read-only display path, resolveAreaPicks, and the additive-fill picker.

* draft-pr-policy: a checked keepalive checkbox is real activity too

lastRealActivityAt() deliberately ignores bot comments so a metadata-only
bump can't dodge the staleness check forever. But checking the "Still
working on this" checkbox is an edit to the bot's own keepalive comment,
not a new comment of the human's own — its author stays
github-actions[bot], so the edit was invisible to the activity check too.

Confirming via the checkbox removed the label and posted "Thanks for
confirming" without ever moving the underlying 60-day clock, so the very
next scheduled run saw the same stale last-activity timestamp and
immediately re-flagged it — contradicting the checkbox's own promise
that checking it "resets this".

Observed on #6326: once its true last activity fell behind the 60-day
window, and only the checkbox (never a new commit or comment) was used
to confirm it, the label thrashed on and off on a roughly 1-2 day loop.

Now a checked keepalive checkbox counts via the comment's updated_at
(when it was toggled), same as any other real activity signal.

Scot BreitenfeldandH. Joe Lee 7b37aac674 review-checklist: make avalanche pruning prefer the already-settled reviewer (#6596)
Every CODEOWNERS "avalanche" (multiple owners of one area simultaneously
requested — on PR creation, on ready_for_review, or when a push first
touches an already-covered area) was resolved by re-running the
load-balancer from scratch, with no memory of who was already the
settled reviewer for that area. Since open-PR review load drifts over
time, this made the pick non-deterministic across repeated events and
caused three related symptoms:

- marking a draft ready for review could swap out reviewers who were
  already assigned (manually or from an earlier pass) for different
  people
- a routine follow-up push could re-avalanche an area and bump the
  already-engaged reviewer for whoever currently has a lighter queue
- a manually re-requested reviewer survived the triggering event (the
  existing forced-pick handling already covers that) but got silently
  removed again on a later event, since two now-requested owners look
  identical to an unpruned avalanche without that memory

Add a persisted per-area "sticky assignment" record (ASSIGNED_PREFIX,
alongside the existing exclusion and manually-added markers) and a
resolveAreaPicks() helper that prefers a valid sticky pick, then a lone
already-requested owner, before ever falling back to a fresh
load-balanced pick. Manual review_requested actions now write to this
record too, so a deliberate reviewer choice holds up across future
runs, not just the run it was made on.

Scot Breitenfeld 1fc781961d Add change-request and manually-added-CODEOWNER lines to review checklist (#6528)
* Add change-request and manually-added-CODEOWNER lines to review checklist

Reviewers who request changes now get their own line under each area
their inline comments touch, whether or not they're a CODEOWNER or a
requested reviewer. CODEOWNERS who are review-requested directly by a
human (rather than auto-picked) get a separate required-approval line,
and their approval is now required for that area's sign-off in addition
to the usual reviewer's.

* Prune reviewers whose area dropped out of scope

A CODEOWNER requested for an area the PR used to touch, before a later
push narrowed the diff, was never removed: touchedAreaOwners only
reflects areas touched right now, so none of the existing avalanche
pruning ever considered them. Reproduced live on PR #6528, where the
branch's diff shrank to just .github/ but gheber/fortnern/mattjala
(owners of unrelated areas) stayed as requested reviewers.

Manually-added CODEOWNERS are exempt, since a human's deliberate
request shouldn't be silently undone by a later push.

* review-checklist: fix avalanche exemption regressing genuine avalanches

#6524 exempted a review_requested login's whole area from avalanche
detection to stop a manual re-request from being undone. But a genuine
CODEOWNERS avalanche's own review_requested sub-events look identical
to that case, and one of them can survive the ready_for_review vs.
review_requested concurrency race (#6530: draft PR marked ready for
review left all 3 CODEOWNERS owners requested instead of pruning to
one, because the surviving run's action was one of the avalanche's own
review_requested events, exempting the whole area).

Replace the exemption with a forced pick: the directly-requested login
still always survives, but now by replacing the rest of that area's
avalanche instead of exempting the area from pruning — so a genuine
avalanche still collapses to one person. Also gate justRequestedLogin
on !isBotSender, matching updatedManuallyAdded's existing reasoning
just above it: the bot's own requestReviewers calls fire this same
event and aren't a human decision.

Scot Breitenfeld 50465b5f6a review-checklist: exempt a just-requested reviewer from avalanche pruning (#6524)
A direct review_requested (e.g. manually re-requesting a reviewer via
the GitHub UI) adds a second currently-requested owner to that
reviewer's area — indistinguishable from an unpruned CODEOWNERS
avalanche, so the avalanche-detection pass immediately removed them
again on the same run. Carve out the login this run's review_requested
action names before running avalanche detection.

Scot Breitenfeld 7858034164 ci(review-checklist): fix three CODEOWNERS reviewer-avalanche bugs (#6485)
Three distinct but related bugs caused the review-checklist bot to
@ mention more reviewers than intended.

**Bug 1 — bot-sender guard (sticky exclusion)**
The bot's own removeRequestedReviewers API calls fire
review_request_removed events that self-trigger the workflow. Without a
guard, that self-triggered run treated its own bookkeeping removal as a
deliberate human decision and added the login to the persisted
exclusion set permanently. Fix: check sender.type === 'Bot' and skip
the exclusion update for bot-originated removals.

**Bug 2 — cancel-in-progress race on opened/ready_for_review**
GitHub fires one review_requested event per CODEOWNERS auto-assigned
owner; each triggers a workflow run. With cancel-in-progress, the
surviving run may be a review_requested rather than the opened event,
bypassing the avalanche-prune branch entirely and leaving all CODEOWNERS
requested. Fix: track hasExistingComment as a proxy for "first
coordination pass" — if no checklist comment exists yet, prune regardless
of which action survives the race.

**Bug 3 — per-area avalanche on synchronize (PR #6484)**
GitHub's CODEOWNERS engine re-fires when a commit first touches a new
CODEOWNERS-covered area, not only on PR open but also on synchronize.
The surviving run fell through to additive fill, saw the area as
"already has owners, skip", and listed all auto-assigned CODEOWNERS.
Fix: before the synchronize-swap and additive-fill paths, detect any
area whose owner-list ∩ existingRequested > 1 (per-area avalanche) and
prune that area to the single load-balanced pick.

84 tests (was 82).

Scot Breitenfeld 884ce02101 ci: replace actions/stale with bot-aware mark-stale script (#6477)
* ci: replace actions/stale with bot-aware mark-stale script

actions/stale uses updatedAt to measure inactivity, so any bot event
(e.g. the /remove-reviewer acknowledgment comment) resets the stale
countdown even when there has been no meaningful human activity for
months.  PR #6332 was last touched by a human on 2026-04-02 but was
not flagged because a reviewer-removal on 2026-06-11 refreshed the
timestamp.

Replace the actions/stale step with a custom mark-stale.js script
(same pattern as alert-stale.js) that only counts non-bot comments,
non-bot review submissions, and commits as meaningful activity.  The
script also removes the stale label if such activity occurs after the
label was applied.

* ci: fix draft-stale keepalive for external contributors

Two bugs with the keepalive checkbox on draft-stale PRs:

1. External contributors (fork authors) lack write access to edit the
   bot's comment, so clicking the checkbox silently fails for them.
   Fix: also treat a new non-bot comment posted after the keepalive
   comment as a sufficient keepalive signal.

2. The stale label could take up to 24 hours to be removed (daily cron
   only). Fix: add an issue_comment.created trigger so draft-pr-policy
   fires immediately when someone comments on a stale draft PR.
   mark-stale and alert-stale are guarded to only run on
   schedule/workflow_dispatch, not on every comment.

Also fix lastRealActivityAt to exclude bot comments (matching
mark-stale.js), so the keepalive and "Thanks for confirming" bot
comments don't count as real activity when measuring staleness.

Scot BreitenfeldandH. Joe Lee 0f1dfcc08e fix(review-checklist): re-request dismissed reviewer on fixup push (#6479)
* fix(review-checklist): re-request dismissed reviewer on fixup push

When a new commit dismisses a prior reviewer's approval, GitHub's
CODEOWNERS engine auto-assigns a fresh (possibly different) owner for
the changed area. The synchronize handler now detects dismissed
area-owners and swaps them back in, removing the fresh CODEOWNERS pick.

Adds planSynchronizeSwaps() pure helper (exported) with 7 unit tests
covering the PR 6475 scenario and edge cases.

* fix(review-checklist): don't remove a fresh pick still needed by another area

planSynchronizeSwaps could remove a fresh CODEOWNERS pick to restore a
dismissed reviewer even when that pick also covered a different,
unrelated touched area — removeRequestedReviewers strips them from the
whole PR, silently uncovering the other area. Now skips removal when
the candidate owns any other touched area.

Also dedupes the consuming loop so a login needed by two areas isn't
requested/removed twice.

5 new tests covering the cross-area guard and its boundaries.

* fix(review-checklist): don't let bot's own reviewer removal create a sticky exclusion

The bot's own removeUnselected/removeRequestedReviewers calls (draft-opened
CODEOWNERS cleanup, stale-exclusion enforcement) fire review_request_removed,
which the workflow also listens on — self-triggering another run. That run
previously read its own bookkeeping removal as a deliberate human decision
and added the login to the persisted exclusion set, permanently blocking
that owner from ever being auto-assigned to the PR again. Guard on
sender.type !== 'Bot' so only human-driven removals become sticky.

* fix(review-checklist): prune CODEOWNERS avalanche regardless of which event wins the race

GitHub's CODEOWNERS engine fires one review_requested event per auto-assigned
owner on PR creation, and each re-triggers this workflow. With concurrency:
cancel-in-progress, whichever run starts last wins — and that's just as
likely to be one of those review_requested runs as the opened run itself.
A surviving review_requested run fell through to the additive-fill branch,
saw every area already "covered" by the avalanche, and pruned nothing.
This hit PR #6479 itself: all 4 CODEOWNERS for .github/ stayed requested.

Branch on whether a checklist comment exists yet instead of which action
survived — that signal is race-resistant: no comment means this is the PR's
first coordination pass no matter which event got here. Threads
hasExistingComment through from run() (defaulting to true, i.e. additive-fill,
on a comment-fetch failure so an API hiccup can't be mistaken for a fresh PR).

2 new tests: the #6479 race itself, and a contrast case confirming a routine
review_requested on an already-established PR still uses additive-fill.

Scot Breitenfeld e251b341d8 CI: base draft PR staleness on real activity, not pr.updated_at (#6472)
pr.updated_at is bumped by metadata-only changes (reviewer
requested/removed, labels, milestone, assignee), letting an

Scot Breitenfeld 2265cf5bdc CI: prune CODEOWNERS avalanche on non-draft PR open (#6474)
* CI: prune CODEOWNERS avalanche on non-draft PR open

GitHub auto-assigns every touched-area CODEOWNER when a non-draft PR
opens. The previous additive-only logic saw all areas already covered
and returned the full auto-assigned set as confirmedRequested, so the
checklist @-mentioned every owner before the final reviewer set was
known.

On opened/reopened (non-draft), now behave like the draft case: prune
to a single load-balanced pick per area via removeUnselected before
posting the checklist, requesting any pick not already on the PR.

* CI: guard reviewer-exclusion update against bot-triggered removals

The bot's own CODEOWNERS cleanup and draft-handling calls fire
review_request_removed events that self-trigger another workflow run.
Without this guard, that run would interpret the bot's own removal as a
deliberate human decision and permanently add the login to the exclusion
set, blocking that owner from ever being auto-assigned to the PR again.

Scot BreitenfeldandH. Joe Lee daa1daf640 CI: fix reviewer-coordination edge cases — draft transitions, unrelated CODEOWNERS, explicit removals (#6465)
review-checklist.js previously tried to enforce a single load-balanced
reviewer per area by actively stripping anyone else who showed up, using a
checklist-comment-existence heuristic (isOpeningRace) to decide when it was
safe to do so. Walking through real PR timelines surfaced several cases
where that heuristic and that stripping behavior did the wrong thing:

- An old PR's first encounter with the bot (or one whose checklist comment
  was deleted) was misdiagnosed as a brand-new PR, forcibly reselecting a
  human-curated reviewer list.
- A CODEOWNER for areas this PR doesn't touch (e.g. a project lead added by
  hand for their judgment) was swept by the same logic as junk
  auto-assignment, with no protection for an existing approval.
- A reviewer who isn't an owner of any touched area was invisible in the
  checklist and untouched by any cleanup path either way.
- A PR that picked up reviewers while non-draft, then was converted to
  draft, had those reviewers wiped out by the next push — converted_to_draft
  isn't in this workflow's trigger list, so there's no event at the actual
  transition to distinguish "noise from this PR's creation" from "a real
  assignment from before it became a draft."
- A reviewer removed via the PR UI could be silently re-added by GitHub's
  own CODEOWNERS engine on a later push, since there was no memory of the
  removal across runs.

Redesign around one principle: the bot should never automatically strip a
reviewer who's already on the PR, manually added or auto-assigned, except
where the policy explicitly calls for it. Concretely:

- coordinateReviewers is now purely additive for non-draft PRs: chooseReviewers
  runs against the *real* existingRequested, so it naturally skips any area
  that already has someone and only fills gaps. This is idempotent and safe
  on every event, eliminating the need for the old race-detection heuristic
  entirely (isOpeningRace, the new-PR/synchronize distinction, and the
  post-request 15s delayed re-clear are all removed as dead weight).
- Pruning — used only where the bot still clears reviewers — is scoped to
  touchedAreaOwners (owners of areas this PR touches, plus catch-all "*"
  owners) instead of the repo-wide allCodeOwners, so a CODEOWNER for
  unrelated areas is never touched.
- Draft handling clears auto-assigned reviewers only at the literal
  opened/reopened-as-draft moment — the one point where "CODEOWNERS noise
  from this PR's creation" and "this PR's actual reviewer state" are
  mechanically the same thing. Every other event while draft leaves existing
  reviewers alone.
- An explicit review_request_removed persists that login to an exclusion
  list embedded as a second hidden marker in the checklist comment (the only
  durable storage available), and every run strips anyone in that list who
  reappears — covering GitHub re-assigning them on a later push. A direct
  review_requested for that exact login overrides the exclusion, since it's
  the strongest available signal that someone individually decided that
  person should be back right now.
- buildBody adds a catch-all "Additional reviewers" line for anyone
  requested who isn't an owner of any touched area, so they're visible and
  their approval is shown (informationally — it doesn't gate any area's
  sign-off), and accepts any owner's approval for an area's sign-off rather
  than only the specifically-assigned one's.

12 new tests cover the buildBody changes and the parseExcluded/serializeExcluded
round-trip; all existing pure-function tests are unchanged.

Scot BreitenfeldandH. Joe Lee a7eeb4fa9b Add stale PR policy with assignee alerts. (#6463)
* Add stale PR/issue policy with assignee alerts instead of auto-close

Ready PRs/issues use actions/stale to label inactivity (30/60 days).
Draft PRs get a longer 90-day window and only reset on an explicit
"still working on this" comment, since pushes/CI activity alone
shouldn't make an abandoned draft look fresh. Nothing is auto-closed:
once a staleness label has persisted past its alert threshold, a
custom script pings the assignee (falling back to requested
reviewers, then the author) to decide whether to keep it open or
close it.

* Scope stale policy to PRs only, not issues

Issue staleness is disabled (days-before-issue-stale: -1) and the
alert script now skips any non-PR item defensively, since this
workflow is meant to address PRs sitting unmerged/unreviewed, not
issue triage.

* Draft stale window 60 days (was 90); drop dead pull_request branch

alert-stale.js's pickAlertTargets is now only ever called with PR
items (filtered upstream in runAlertStale), so the pull_request
check around the requested-reviewers lookup was dead code.

* Set persist-credentials: false on checkout steps

Fixes two zizmor notes: these checkouts only need to read local
script files for github-script's require(), so there's no reason
to persist the GITHUB_TOKEN in git config afterward.

* Use a keep-alive checkbox instead of a magic comment phrase for drafts

Checking a box in the bot's own stale-notice comment is more
discoverable than requiring an exact phrase, and the live checkbox
state can be read straight off that comment's current body on each
run instead of scanning new comments for a regex match.

Scot Breitenfeld 4d3559c5b1 CI: fix buildBody sign-off and add non-CODEOWNER reviewer tests (#6461)
* CI: fix buildBody to accept any owner approval, not only the assigned reviewer

PR #6446 narrowed the approver lookup to effectiveReviewers (the confirmed-
requested subset), inadvertently breaking the case where a non-assigned owner
approves. Restore the original intent: any CODEOWNER's approval signs off an
area; fall back to effectiveReviewers only when no CODEOWNER is assigned.

* text updates

* CI: add tests for non-CODEOWNER reviewer sign-off path (#6446)

Three tests cover the nonOwnerReviewers fallback introduced in #6446:
- pending mention when a non-owner is manually assigned
- non-owner approval signs off an area with no CODEOWNER assigned
- non-owner approval does NOT sign off when a CODEOWNER was assigned

* CI: restore review_requested/review_request_removed triggers

These were dropped in #6453 when ready_for_review was added, breaking
automatic checklist updates on manual reviewer changes.

Both events fall through to the preserve-existing path in
coordinateReviewers when a checklist already exists, so the checklist
body is simply rebuilt with the current requested_reviewers set.

Also extend the opening-race detection (previously called isFirstSyncRace)
to cover review_requested: for any PR, CODEOWNERS auto-assignment fires
review_requested shortly after opened, and with cancel-in-progress: true
that run can cancel the opened run. If no checklist exists yet, treat the
review_requested event as a new-PR event and run full selection.

* CI: show only one reviewer per checklist area

Each area's pending mention now shows the primary (first) effective reviewer
rather than all confirmed-requested owners joined with commas.

* CI: revert to showing all confirmed reviewers per checklist area

A manually added person who is also a CODEOWNER for that area should be
shown alongside the load-balanced pick, not hidden. "One reviewer per area"
only describes chooseReviewers' default selection, not a display constraint.

Scot Breitenfeld ec33e7573c CI: fix reviewer workflows for already-reviewed and draft PRs (#6453)
* CI: skip reviewer removal when they have already submitted a review

GitHub's API rejects removeRequestedReviewers for users who have already
reviewed; detect that case upfront via listReviews and report it clearly
instead of surfacing a cryptic API error.

* CI: defer reviewer assignment for draft PRs until ready for review

Add ready_for_review to the pull_request_target trigger so the workflow
fires when a draft is promoted.  In the script, skip requestReviewers
(and the CODEOWNERS auto-assignment cleanup second pass) while the PR is
a draft; still assign the PR author and strip any reviewers GitHub
auto-assigned.  When the PR is marked ready, treat it like a fresh open
and run the full load-balanced reviewer selection.

* CI: fix synchronize race — treat first synchronize as new PR when opened was cancelled

When a fork PR is created, GitHub fires both opened and synchronize.
With cancel-in-progress: true the synchronize run often wins, and the
opened run (which clears CODEOWNERS auto-assignments) is cancelled before
it completes.  Detect this: if synchronize fires but no checklist comment
exists yet, run the full new-PR path (enforceSelection + load-balanced
reviewer assignment) instead of silently carrying forward all auto-assigned
reviewers.

* CI: enforce reviewer selection before posting @mentions

On synchronize, run enforceSelection against the ideal load-balanced
pick before building the checklist body so the @mentions are never
sent until the reviewer list is actually correct.  Re-fetch the PR
after cleanup so confirmedRequested reflects reality, not the pre-
cleanup snapshot.

For workflow_run (review submitted), reviewer assignment is intentionally
left unchanged but @mentions are filtered to the ideal selection so
CODEOWNERS extras don't generate spurious notifications on comment edits.

* CI: preserve manually added reviewers on synchronize

Reverting the enforceSelection call on the non-first-run synchronize
path.  There is no API way to distinguish CODEOWNERS auto-assignments
from manually added reviewers, so enforcing the load-balanced selection
on every synchronize would silently remove intentional additions.

The initial cleanup (opened or first-synchronize via openedWasSkipped)
already produces a correct reviewer list; subsequent synchronize and
workflow_run events carry it forward unchanged.

* CI: pin actions/github-script to commit hash in remove-reviewer.yml

zizmor requires actions to be pinned to a commit hash rather than a tag.
Use the same pinned hash (ed597411d8f924073f98dfc5c65a23a2325f34cd, v8.0.0)
already used in review-checklist.yml.

* CI: refactor review-checklist.js for readability

Extract the reviewer coordination logic out of the monolithic run()
function into named module-level helpers:

  checklistExists()          — single responsibility: does a checklist
                               comment already exist on the PR?
  removeUnselected()         — remove CODEOWNERS auto-assignments not in
                               the load-balanced selection set
  requestReviewers()         — request each reviewer individually so one
                               bad login cannot block the rest
  removeUnselectedAfterDelay() — 15-second wait + re-fetch + re-enforce
                               for GitHub's async auto-assignment race
  coordinateReviewers()      — top-level dispatcher; the four event paths
                               (read-only, synchronize-normal, new-PR/draft,
                               new-PR/non-draft) are now explicit branches
                               with labelled comments instead of nested ifs

run() is now a straight pipeline of 8 numbered steps with no nested
async functions. Behaviour is unchanged.

* CI: extract convertGlobToRegex and use github.paginate consistently

Extract glob-to-regex conversion into a standalone helper and replace
manual pagination loops for listFiles and listReviews with github.paginate,
matching the existing style used for listComments and pulls.list.

* CI: restrict remove-reviewer workflow to main repo only

Adds a github.repository guard so the job does not run in forks,
preventing unintended resource consumption and command execution
against fork PRs.

* CI: restrict test-maven-packages workflow to main repo only

Adds github.repository guards to all three jobs so the workflow
does not evaluate in forks, preventing spurious "workflow file issue"
failures on push events in forked repositories.

* Revert "CI: restrict test-maven-packages workflow to main repo only"

added in their place, that person previously got no checklist mention and
their approval did not check the box.

For any area with no CODEOWNER in the requested set, fall back to
non-CODEOWNER reviewers (anyone assigned who is not an owner of any
touched area). They are shown in the mention and their approval counts
as sign-off for that area.

* review-checklist: update checklist on reviewer add/remove

Adding or removing a reviewer did not trigger a workflow run, leaving
the checklist comment stale until the next push.

Add review_requested and review_request_removed to the pull_request_target
activity types so the checklist updates immediately when a reviewer is
manually added or removed.

Scot Breitenfeld 65fc219bc9 review-checklist: enforce one load-balanced reviewer and fix checklist display (#6439)
* review-checklist: show all requested owners per area in checklist

buildBody was using area.owners.find() — picking the first CODEOWNERS-listed
owner in the requested set. This broke reviewer swaps (removing @A and adding
@B would show @C, the next CODEOWNERS entry, not @B) and also failed to
reflect GitHub's CODEOWNERS auto-assignment, which requests all owners.

Switch to area.owners.filter() so every requested owner for an area is
mentioned in that row. Approval logic is unchanged: any owner approval
still checks the box.

* review-checklist: enforce one load-balanced reviewer per area

GitHub's CODEOWNERS auto-assignment requests all owners of touched files
when a PR opens, before the workflow runs. The script was then seeing them
already assigned and skipping its own selection entirely.

On opened/reopened: select one load-balanced reviewer per area (ignoring
GitHub's pre-assigned set), remove any auto-assigned CODEOWNERS not in the
selection, then add the chosen reviewer. Only code owners are removed —
manually-added non-owner reviewers are left untouched.

On synchronize: keep existing assignments (reviewer may have already started).

confirmedRequested now starts empty and is populated only with the script's
selection, so the checklist only mentions owners that were explicitly chosen.

* review-checklist: retry reviewer cleanup to handle GitHub auto-assign race

GitHub's CODEOWNERS auto-assignment can fire after the workflow starts,
re-adding extra reviewers after we remove them. Add a 15-second wait
followed by a second cleanup pass on opened/reopened events.

Extract the removal loop into enforceSelection() so both passes share
the same logic.

* zizmor: suppress template-injection for PR #6356 workflow files

Add zizmor_config.yml to ignore template-injection findings in the
setup-jextract action and maven/ctest workflow files introduced in
PR #6356, where inputs are caller-controlled but not user-controlled.

* review-checklist: don't re-assign reviewers on synchronize

On synchronize, chooseReviewers saw no owner assigned (because the
reviewer was manually removed) and re-added one via requestReviewers,
overriding the manual removal.

Reviewer assignment now only happens on opened/reopened. Synchronize
only updates the checklist display based on whoever is currently
assigned — manual removals are respected.

* zizmor: skip upload-sarif failure on fork PRs

* zizmor: move config out of workflows dir to fix GitHub Actions parse error

GitHub Actions parses all .yml files in .github/workflows/ as workflow
files; zizmor_config.yml there caused "unexpected value 'rules'" because
rules: is not valid workflow syntax. Moved to .github/zizmor.yml and
updated the --config path in zizmor.yml accordingly.

* review-checklist: retry on transient 401 from GitHub API

GitHub's API intermittently returns 401 on write operations
(issues.addAssignees, issues.createComment) even when the token has
Issues: write and PullRequests: write — read-only calls succeed in the
same run. The github-script action excludes 401 from retries by default.
Removing 401 from retry-exempt-status-codes and setting retries: 3
handles these transient failures with exponential backoff.

* review-checklist: fix checklist mention when non-requested owner approves

The mention in each checklist row was derived from the approver (if any),
so when a different area owner happened to approve first, the mention
changed from the assigned reviewer to the approver. Fix by decoupling
sign-off detection from display: signedOff now uses .some() so any
owner's approval checks the box, while the mention always shows the
confirmed-requested reviewer(s) via .filter(). Also shows multiple
reviewers when one is manually added alongside the load-balanced
selection.

* review-checklist: show approver name when signed off, requested reviewer(s) when pending

When an area is signed off, replace the mention with the approver so the
checklist shows who actually reviewed it (which may differ from whoever
was load-balanced as the requested reviewer). When pending, show all
confirmed-requested reviewers — the one load-balanced pick normally, but
two if a reviewer was manually added alongside it.

* zizmor: remove config file and --config flag

The ignored files (ctest.yml, maven-deploy.yml, maven-staging.yml,
setup-jextract/action.yml) had template-injection findings on
inputs.* references, which are not attacker-controllable. Rather than
suppressing them via a config file, let all findings surface in the
Security tab and address them individually if needed.

Scot BreitenfeldandH. Joe Lee 64036c6d03 CI: use pull_request_target so review-checklist runs on fork PRs (#6435)
* CI: use pull_request_target so review-checklist runs on fork PRs

pull_request events from forks receive a read-only GITHUB_TOKEN and
are skipped by the job condition, so no checklist comment is posted
and no reviewers are assigned.  Switching to pull_request_target fixes
this: GitHub always executes the workflow from the base repo
(HDFGroup/hdf5) with a full write token, regardless of whether the PR
comes from a fork.  The fork's code is never checked out or executed.

The cross-repo guard (head.repo.full_name == github.repository) is
removed since it is no longer needed — pull_request_target only fires
for PRs targeting this repo's branches.

* CI: replace pull_request_target with safe two-workflow pattern for fork PRs

pull_request_target carries a GitHub security warning because it grants
write access to the privileged workflow at trigger time, which is risky
if the checkout is ever changed to use the fork's head ref.

Replace it with the recommended two-workflow pattern:
- review-checklist-gather.yml fires on pull_request (read-only, safe
  for forks) and uploads the PR number as a short-lived artifact.
- review-checklist.yml fires on workflow_run when the gather job
  completes, downloads the artifact for the PR number, then posts the
  checklist comment and assigns reviewers with a full write token.
  It never executes any code from the fork.

The script gains a prNumber parameter so the main workflow can supply
the PR number it read from the artifact; falls back to the event
payload for pull_request_review triggers.

* review-checklist: fix prAuthor crash and stale comment for workflow_run context

In the workflow_run path context.payload.pull_request is undefined, so
reading .user.login from it throws a TypeError. Use prData.user.login
instead — prData is already fetched from the API at step 5.

Also remove the stale comment saying fork PRs require pull_request_target;
they are now handled via the two-workflow pattern.

* CI: revert to pull_request_target, drop two-workflow pattern

The workflow_run approach adds a second hop before the checklist posts
and introduced a context.payload.pull_request crash in the gather path.
pull_request_target is simpler and equally safe here: GitHub always
executes the workflow from HDFGroup/hdf5:develop with a full write
token — the fork's code is never checked out or executed.

* CI: add zizmor workflow for GitHub Actions security analysis

zizmor is a static analyser that catches security issues specific to
GitHub Actions: pull_request_target misuse, expression injection,
unpinned action SHAs, and overly broad permissions.

Runs on push to develop and on PRs that touch .github/, uploads SARIF
to the Security tab (free for public repos via Advanced Security), and
annotates PR diffs inline with any findings.

* CI: run zizmor via pip instead of third-party action

Replace zizmorcore/zizmor-action (third-party) with a direct pip install
of zizmor==1.25.2. SARIF output is still uploaded to the Security tab via
github/codeql-action/upload-sarif (first-party). The only actions used
are from actions/ and github/, both trusted.

* CI: fix codeql-action pin to commit SHA (was tag object SHA)

* CI: add persist-credentials: false to review-checklist checkout

* CI: hash-pin zizmor pip install; suppress expected pull-request-target finding

- zizmor.yml: pin zizmor wheel to its SHA256 hash via --require-hashes so
  the install is fully reproducible and passes zizmor's unpinned-tools audit
- review-checklist.yml: add zizmor: ignore[pull-request-target] comment so
  zizmor does not flag its own host workflow; document why the usage is safe

* CI: update actions to Node.js 24 ahead of June 16 deprecation

- actions/checkout:          v4.2.2 → v5.0.1  (node20 → node24)
- actions/github-script:     v7.0.1 → v8.0.0  (node20 → node24)
- github/codeql-action:      v3.36.2 → v4.36.2 (node20 → node24; v3 deprecated Dec 2026)

* CI: fix pip hash-pinning syntax — hash must be in requirements file

* CI: zizmor step continue-on-error so SARIF upload always runs

* review-checklist: skip pull_request_review on fork PRs (read-only token)

GitHub only grants a read-only GITHUB_TOKEN for pull_request_review events
when the PR originates from a fork, so the comment post fails with 403.
Restrict the review trigger to same-repo PRs; pull_request_target already
handles fork PRs for the open/sync/reopen case with a full write token.

* review-checklist: route reviews through workflow_run for fork PR support

pull_request_review grants only a read-only token for fork PRs, causing
a 403 when posting the checklist comment. Fix with a two-path design:

- pull_request_target handles open/sync/reopen for all PRs (full token,
  immediate)
- A new gather workflow (review-checklist-gather.yml) fires on
  pull_request_review, saves the PR number as an artifact, and exits.
  The main workflow then fires via workflow_run with a full write token.

The script gains prNumber and isReview parameters. isReview suppresses
reviewer assignment (which only applies on open/sync/reopen). prAuthor
is sourced from prData.user.login since context.payload.pull_request is
not populated in the workflow_run context.

* review-checklist: simplify to pull_request_target only, drop gather workflow

pull_request_review triggers a fork workflow approval gate for first-time
contributors, which blocks every PR. There is no pull_request_review_target
equivalent in GitHub Actions.

Instead, rely on pull_request_target (opened/synchronize/reopened) only.
Approval boxes are still evaluated correctly: computeApprovals() re-reads
all existing reviews on every push, so boxes auto-check the next time the
author pushes after a reviewer approves.

Also restores the simpler script signature (no prNumber/isReview params)
and sources prAuthor from prData.user.login which works in all contexts.

* review-checklist: auto-check approval boxes on review via workflow_run

Add a minimal gather workflow (review-checklist-gather.yml) triggered by
pull_request_review that completes immediately with a read-only token. The
main workflow now also triggers via workflow_run on gather completion, giving
it the full write token it needs to update the checklist comment.

In workflow_run context, the script looks up the PR by head SHA (since
workflow_run.pull_requests is empty for fork PRs) and skips reviewer
assignment — only approval box state is updated.

Requires the repo "Fork pull request workflows from outside collaborators"
setting to be "Require approval for first-time contributors", which is
already the current setting.

Scot Breitenfeld f3e380ce17 Add per-area review checklist action and restructure CODEOWNERS (#6418)
* Add per-area review checklist action and restructure CODEOWNERS

CODEOWNERS:
- Replace 11-person global catch-all with specific path rules per area,
  assigning reviewers based on their actual strengths
- Global fallback is now @fortnern only for uncovered root files
- Remove @derobins, @epourmal, @qkoziol, @mkitti per team discussion

review-checklist GitHub Action (.github/workflows/review-checklist.yml):
- Posts a per-area sign-off checklist on every PR to develop (non-forks only)
- Reviewer lists and path patterns derived directly from CODEOWNERS
- Assigns ONE reviewer per area using fewest-open-PRs load balancing
- Complex changes (≥ 300 lines or any public/developer header modified)
  always go to the first (senior) owner listed; routine changes are
  load-balanced across all owners (500-line threshold for test/)
- Cohesion: reuses an already-assigned reviewer for related areas where
  owner lists overlap, avoiding e.g. src/ and test/ going to different people
- Skips auto-assign if an area owner is already manually requested
- Checklist auto-checks when an owner approves; tracks latest review state
  so a subsequent "request changes" unchecks the box

The previous regex only matched *public.h and *develop.h, missing hdf5.h
itself (the umbrella header), all VFD driver headers included by hdf5.h
(H5FDcore.h, H5FDmpio.h, H5FDsubfiling.h, etc.), and VOL connector headers
(H5VLconnector.h, H5VLnative.h, etc.).  Changes to any of these now
correctly trigger senior-owner assignment.
