Summary

  • keep stable canary PRs open after canary validation and prepare the complete non-admin fleet before authorizing any campaign merge
  • bind the commit pass to exact PR numbers, branches, delivery generations, head SHAs, plan identity, source commit, and verified no-change heads
  • persist idempotent, plan-bound Maint 71 continuations and treat expected review/check waits as successful continuation states
  • declare transitive source-delta dependencies in the typed sync manifest instead of hard-coding them in the scope planner
  • run Health 83 once per completed immutable campaign plan in addition to its weekly report

Safety properties

  • reviewer settlement still requires one substantive response when available, never all configured reviewers; bounded capacity and non-response degradation remains unchanged
  • active non-outdated review threads, failed required checks, unsigned heads, stale authorizations, or missing no-change evidence still fail closed
  • the sync:delivery-staging hold remains on prepared PRs until the Maint 71 campaign commit pass succeeds
  • a missing PR is no longer interpreted as a no-change repository; Maint 71 rechecks the exact recorded default-branch head and required checks

Validation

  • node --test .github/scripts/tests/sync_pr_merge_contract.test.js .github/scripts/tests/sync_dependency_campaign.test.js .github/scripts/tests/sync-run-contract.test.js (97 passed)
  • python -m pytest -q tests/scripts/test_sync_manifest_compiler.py tests/scripts/test_scope_consumer_sync_plan.py tests/workflows/test_dependency_sync_efficiency_workflow.py tests/workflows/test_sync_delivery_liveness.py tests/workflows/test_sync_manifest_delivery.py (58 passed)
  • python -m pytest -q tests/workflows (866 passed, 3 policy-gated skips)
  • actionlint on Maint 68, Maint 71, Maint 82, and Health 83
  • git diff --check

Rollout

This is intentionally a draft until the exact-head CI and post-push review window are clean. After merge, run one no-filter Maint 68 canary cycle and verify that candidate PRs remain held through promotion, the campaign authorization covers every registered non-admin repo, and Health 83 is dispatched once for the completed plan.

Summary by CodeRabbit

  • New Features

    • Added campaign-based synchronization with repository-specific selection and exact-head authorization.
    • Added immutable continuation tracking to prevent duplicate or unsafe follow-up runs.
    • Added manifest dependency support, including transitive dependency resolution and cycle validation.
    • Added campaign plan IDs and trigger reasons to workflow dispatch and run names.
  • Bug Fixes

    • Improved handling of unchanged repositories and incomplete canary evidence without unnecessarily failing runs.
  • Documentation

    • Updated integration, workflow, maintenance, and CI guidance for campaign preparation, promotion, authorization, and dependency configuration.

Review Change Stack

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 29 minutes

Limit details: You’ve used all 1 included review currently available under your plan. You completed 107 included PR reviews in the past 7 days; at that activity level, included reviews refill at 1 review per hour.

Your organization has reached its usage spending cap. Adjust your spending cap in the billing tab.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

📝 Walkthrough

Walkthrough

This change adds typed transitive manifest dependencies and extends the Maint 68/71/82 sync lifecycle with campaign lanes, immutable no-change evidence, exact-head authorization, prepare-only execution, keyed continuations, and Health 83 campaign reporting.

Changes

Sync orchestration

Layer / File(s) Summary
Typed manifest dependencies
scripts/sync_manifest_compiler.py, scripts/scope_consumer_sync_plan.py, docs/contracts/schemas/consumer-sync-plan-v1.schema.json, tests/scripts/*
Manifest entries now support validated requires paths. Compilation rejects unknown targets and cycles. Scope selection expands dependencies transitively.
Campaign contracts and authorization
.github/scripts/sync_run_contract.js, .github/scripts/sync_pr_merge_contract.js, .github/scripts/__tests__/*
The sync contracts now create plan-bound no-change evidence, select repository-specific lanes, validate campaign authorization, and preserve keyed immutable handoffs.
Campaign preparation and merge execution
.github/scripts/maint71_merge_sync_prs.js, .github/workflows/maint-68-sync-consumer-repos.yml, .github/workflows/maint-71-merge-sync-prs.yml, tests/workflows/*
Maint 68 produces campaign evidence. Maint 71 prepares campaign PRs, validates exact-head authorization, recovers eligible merged results, and merges only authorized campaign rows.
Immutable continuations and operational documentation
.github/scripts/sync_dependency_campaign.js, .github/workflows/maint-82-sync-dependency-campaign.yml, .github/workflows/health-83-dependency-sync-efficiency.yml, docs/*
Continuation handoffs retain immutable plan metadata and deterministic keys. Maint 82 suppresses duplicate dispatches. Documentation describes the campaign lifecycle and Health 83 reporting.

Estimated code review effort: 5 (Critical) | ~120 minutes

Merge Risk: 🟠 High · up to 63a7c

The change can still allow a candidate PR to proceed without the required candidate evidence, while mixed campaign evidence may abort continuations and concurrent phases may act on inconsistent plans. That creates a material risk of incorrect merges or an incompletely synchronized fleet, so the PR should not merge until these safeguards are fixed or explicitly accepted by the owner.

When a campaign commit pass merges one repository and a later merge fails,
resume now recognizes the authorized exact PR/head from closed PR history
instead of recording target_missing. buildCampaignCommitAuthorization also
accepts merged rows when rebuilding authorization for the remaining repos.

Closer recovery for the P1 campaign-resume gap:

  • Added selectLatestMergedSyncPr and campaign-commit recovery in maint71_merge_sync_prs.js: when a campaign commit pass resumes with fleet authorization but no open stable PR, the lane now recovers the authorized exact PR/head from closed merged history instead of recording target_missing.
  • buildCampaignCommitAuthorization now accepts merged rows when rebuilding authorization after a partial commit pass.
  • Tests added in sync_pr_merge_contract.test.js (59/59 pass locally).

Head a009f590d. Merge deferred until the 7-minute post-push review window elapses and CI re-checks the new head.

414-436: 🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

Reject incomplete continuation bindings before planning.

Lines 414-436 plan a transient continuation when continuation.key, plan_id, plan_scope, scope_base_sha, or source_commit is empty. normalizeDeliveryHandoff converts each missing field to an empty string, so a malformed or legacy handoff can dispatch Maint 71 without its immutable authorization binding.

Require a non-empty continuation key and all immutable handoff fields before adding the record to dueByLane. Require lane-specific evidence before planning a lane that depends on that evidence.

The PR objective requires plan-bound continuations that fail closed.

Inline comments:
In @.github/scripts/__tests__/sync_pr_merge_contract.test.js:
- Around line 207-212: Update the test call to buildCampaignCommitAuthorization
so the prepared report row includes a valid sourceCommit, ensuring authorized is
false solely because status is checks_pending and the campaign_prepared gate is
exercised.

In @.github/scripts/__tests__/sync-run-contract.test.js:
- Around line 14-31: Add negative-path tests for buildNoChangeEvidence covering
plan ID, plan scope, scope-base SHA, source commit, and consumer_head_sha
mismatches or invalid values, plus duplicate repository rows. Assert each case
returns ok false and includes the corresponding fail-closed error identifier,
while preserving the existing success-path test.

In @.github/scripts/maint71_merge_sync_prs.js:
- Around line 1991-1995: Update the authorization argument in
candidateEvidenceAllowsMutation so campaignCommitAuthorization is usable only
when requestedSyncHash is the campaign lane and the parsed authorization
satisfies the established campaign authorization schema validation; do not let
arbitrary parsed JSON, including empty or unrelated objects, authorize candidate
mutation.
- Around line 2245-2254: Update .github/scripts/maint71_merge_sync_prs.js lines
2245-2254 so isBlockingSyncSystemFailure treats campaign_prepared as
non-blocking and buildCampaignCommitAuthorization accepts campaign_prepared
rows. Update .github/workflows/maint-71-merge-sync-prs.yml lines 414-417 so
candidatePromotionDecision, candidateRefreshDecision, and
deliveryRefreshDecision accept campaign_prepared alongside the previous
statuses.
- Around line 1771-1781: The handoff construction around
delivery_handoff_records currently embeds full fleet-wide campaign evidence in
every record; update the campaign_no_change_evidence_json value to retain only
the current repository’s evidence row, or an artifact/digest reference, while
preserving the existing campaign-only condition and avoiding O(R×E) payload
growth.
- Around line 1413-1459: Update the campaign recovery block around
selectLatestMergedSyncPr so it also runs when prepareOnly is true, using
syncBranchForHash(selectedSyncHash), expectedPlanId, and expectedSourceCommit to
identify the merged PR. Record the recovered result as a terminal merged row
before the target_missing fallback, preserving the existing authorization and
no-change checks.

In @.github/scripts/sync_pr_merge_contract.js:
- Around line 1121-1123: Update candidatePromotionDecision in
.github/scripts/sync_pr_merge_contract.js at lines 1121-1123 to accept
SYNC_CAMPAIGN_SELECTOR alongside the existing selector, matching the sibling
decisions while retaining campaign_prepared. Update
.github/scripts/__tests__/sync_pr_merge_contract.test.js at lines 111-133 so
inputs.sync_hash is 'campaign', exercising the campaign selector with
campaign_prepared.

In @.github/scripts/sync_run_contract.js:
- Around line 7-62: Extract the duplicated validation logic from
buildNoChangeEvidence and buildNoChangeCanaryEvidence into one shared builder
parameterized by errorPrefix, schema, and evidenceSource. Keep both exported
functions as thin wrappers, with buildNoChangeCanaryEvidence mapping
expectedCanaries to expectedRepositories and using the canary-specific prefix,
source, and schema; preserve existing caller-facing names and behavior.

Apply the same fix in @.github/scripts/maint71_merge_sync_prs.js around lines
780 - 825: The same duplicated validation pattern appears in the Maint 71
candidate and campaign paths.

In @.github/workflows/maint-68-sync-consumer-repos.yml:
- Around line 1743-1755: Update the campaignEvidence merge around
rawCanaryEvidence, canaryRows, and deliveryBaseline.evidence.results to
deduplicate rows by repository identifier, with each canary row taking
precedence over any delivery row for the same repository. Preserve all unique
canary and delivery evidence before writing campaign_evidence_json.

In @.github/workflows/maint-71-merge-sync-prs.yml:
- Around line 269-272: Validate the computed selector before any GITHUB_OUTPUT
writes in the selector-handling step, accepting only the known lane values
candidate and campaign; reject all other values, including newline-containing
inputs, and preserve the existing derived boolean outputs for valid selectors.
- Around line 599-607: The campaign path can dispatch both Maint 68 canary and
promote phases because the refresh steps are not mutually exclusive. Update the
condition for Refresh stale delivery bases so it skips when
steps.refresh_candidate has run or dispatched, while preserving its existing
behavior for non-campaign runs.
- Around line 379-386: The promotion gate must remain fail-closed when candidate
evidence validation is incomplete. Update the condition for Promote complete
exact-plan canary evidence to require both a successful
candidate_evidence_validation outcome and its authorized output being true,
while preserving the existing candidatePromotionDecision requirement.
- Around line 542-575: Update the measurement gate’s allowed status Set to
include stale_closed so superseded PR rows are treated as terminal. Make the
Health 83 duplicate check durable beyond the first 100 workflow_dispatch runs by
paginating listWorkflowRuns or using an equivalent plan-ID idempotency check,
while preserving the existing title-based match for the current plan.

In @.github/workflows/maint-82-sync-dependency-campaign.yml:
- Around line 229-245: Update the continuation dispatch checks around
recentTitles, activeTitles, and the title comparison so completed workflow runs
do not suppress due retries; use activeTitles as the dispatch exclusion source,
and remove or bound any completed-run guard to no longer than the continuation
retry interval. Preserve the existing same-execution duplicate prevention at the
guard around line 276.

In `@docs/ops/CONSUMER_REPO_MAINTENANCE.md`:
- Around line 476-478: Expand the operator guidance in the campaign hold-state
section to define recovery actions for campaign_authorization_required,
campaign_prepared, campaign_no_change_verified, and target_missing with reason
campaign_pr_and_no_change_evidence_missing. Explicitly describe resuming after a
partial commit pass by rebuilding authorization from closed merged history, and
document that stranske/Collab-Admin is excluded from the authorized repository
set with its reason.

In `@scripts/scope_consumer_sync_plan.py`:
- Around line 60-74: Update the dependency traversal around entries_by_target
and pending so a plan entry with requires set to null is treated as having no
dependencies, preventing the for loop from raising TypeError. Preserve the
existing dependency-cycle termination and deterministic output behavior.

In `@tests/scripts/test_scope_consumer_sync_plan.py`:
- Around line 122-143: Add a test alongside
test_source_delta_expands_transitive_manifest_dependencies that constructs
mutually dependent entries for scripts/x and scripts/y, invokes select_plan in
source-delta mode with scripts/x changed, and asserts the traversal terminates
with each target included once in dependency order and
evidence["dependency_targets"] containing only scripts/y.

In `@tests/workflows/test_sync_delivery_liveness.py`:
- Around line 13-16: Strengthen the workflow safety-gate tests: in
tests/workflows/test_sync_delivery_liveness.py lines 13-16, assert the
authorization condition steps.campaign_authorization.outputs.authorized ==
'true', PREPARE_ONLY_INPUT, and CAMPAIGN_COMMIT_AUTHORIZATION_JSON; in
tests/workflows/test_sync_manifest_delivery.py lines 334-337, use the existing
yaml.safe_load step-name indexing to verify Check and merge sync PRs precedes
Authorize exact-head fleet commit, which precedes Commit prepared sync campaign.

Stall-escalator recovery on exact head cc631d43a5a1799131f07be9416aa7bd81eb0947:

  • Independent fallback review identified a fresh P1: a new Maint 82 continuation re-enters the campaign prepare pass without the prior commit authorization, so an already-merged fleet row could still become target_missing.
  • The prepare pass now recovers the newest trusted merged delivery bound to the immutable plan, source commit, stable branch, and delivery record; missing generation still fails closed.
  • Added an end-to-end Maint 71 regression for a partial campaign resumed through a fresh prepare pass.
  • Validation: JavaScript syntax, git diff --check, and the focused campaign/merge/run contract suite (100/100) pass.

Merge remains deferred. At or after 2026-08-16T07:11:08Z, re-read the unchanged head, review threads and reviewer state, authoritative/full checks, hidden suites, merge state, and run exact synthetic-candidate Gate evidence for the new merge candidate before any normal merge.

Dedupe overlapping canary/delivery no-change evidence before Maint 71 dispatch,
require a validated campaign authorization schema instead of truthy JSON,
accept campaign-selector reports in candidate promotion checks, prevent campaign
runs from double-dispatching Maint 68 refresh phases, and stop completed Maint 71
runs from blocking keyed continuation retries.

Closer review-thread batch (2a255a9e2)

Addressed CodeRabbit safety threads from the campaign two-phase PR:

  1. Critical — duplicate repos in campaign evidence (maint-68): mergeCampaignNoChangeEvidence() now dedupes canary + delivery no-change rows by repo (canary wins) before Maint 71 dispatch.
  2. Major — authorization truthiness (maint71): hasCampaignCommitAuthorization() requires schema workflows.sync-campaign-commit-authorization/v1, authorized: true, and non-empty rows — empty {} no longer authorizes candidate mutation.
  3. Major — campaign promotion selector (sync_pr_merge_contract): candidatePromotionDecision accepts both candidate and campaign selector reports when checking campaign_prepared rows.
  4. Major — double Maint 68 refresh (maint-71): candidate-base refresh no longer runs on campaign selector runs (delivery refresh only).
  5. Major — continuation retry blocked by completed runs (maint-82): keyed continuation dispatch now checks only active Maint 71 titles, not completed run titles.

Tests: node --test sync-run-contract.test.js sync_pr_merge_contract.test.js — 69/69 pass.

Merge remains deferred until CI on head 2a255a9e2 completes, the 7-minute post-push window elapses, and remaining review threads are dispositioned.

Stall-escalator review-thread recovery on exact head 63a7c06:\n\n- Closed all 10 remaining current CodeRabbit threads: fail-closed selector and promotion gates, durable Health 83 idempotency, shared no-change evidence validation, null-safe dependency traversal, focused negative/cycle/order tests, and operator recovery guidance.\n- Validation passed: 71 JavaScript contract tests, 26 Python workflow/scoping tests, template sync/completeness, actionlint, Node syntax checks, and git diff --check.\n\nNo merge attempted. The next scheduled pass must re-read this unchanged head after the seven-minute post-push window, enumerate all exact-head suites, confirm required checks and zero active non-outdated threads, and prove the fresh synthetic merge candidate before any normal merge.

677-678: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

The selector == 'delivery' branch is now unreachable.

Lines 270-272 restrict the selector to candidate, campaign, or an empty string. steps.candidate_mode.outputs.selector can therefore never equal delivery. The condition still works because the campaign clause carries it, but the stale clause implies a lane that the allowlist rejects. Remove it, or add delivery to the allowlist if that lane must remain dispatchable.

2016-2022: 🔒 Security & Privacy | 🟠 Major | ⚡ Quick win

Bind campaign authorization to the campaign lane.

Line 2021 accepts a valid campaign authorization during a candidate run. The campaign-specific gate at Lines 2034-2051 does not run in that lane. A candidate PR can then merge without candidate evidence.

Only use campaign authorization when requestedSyncHash === 'campaign'.

- Around line 261-268: Update the tests for hasCampaignCommitAuthorization and
campaignAuthorizationAllowsMerge to isolate the schema gate: add a valid-schema
authorization payload with empty rows that is rejected, and a wrong-schema
payload with non-empty rows that is also rejected.

In @.github/scripts/__tests__/sync-run-contract.test.js:
- Around line 170-175: Extend the test for mergeCampaignNoChangeEvidence to
assert that the merged document preserves the delivery schema and version
values, alongside the existing row deduplication assertions. Use the expected
schema and version from delivery so changes to the merge spread cannot silently
remove them.

In @.github/scripts/maint71_merge_sync_prs.js:
- Around line 789-824: Update the evidence handling in
.github/scripts/maint71_merge_sync_prs.js lines 789-824 so only the document
matching requestedSyncHash is parsed and the opposite-lane evidence uses an
empty map; update .github/workflows/maint-82-sync-dependency-campaign.yml lines
256-263 so only the evidence document matching selector is forwarded. Add a
regression test covering a campaign continuation containing both evidence
fields.

openai

  • Model: gpt-5.6-terra
  • Verdict: PASS
  • Confidence: 87%
  • Scores:
    • Correctness: 9.0/10
    • Completeness: 9.0/10
    • Quality: 8.0/10
    • Testing: 9.0/10
    • Risks: 8.0/10
  • Summary: The changes implement an immutable, plan-bound campaign commit pass: delivery and canary no-change evidence are validated against plan identity, scope, source commit, and recorded heads; duplicate or malformed evidence fails closed. Maint 71 now records and resumes plan-bound continuations, treats expected review/check waiting states as continuable rather than terminal failures, and retains the delivery-staging hold until the campaign pass succeeds. The merge contract changes bind PR number, branch, generation, SHA, authorization, review state, and required checks, including revalidation of recorded default-branch heads when a PR is missing rather than treating that condition as no change. Manifest/compiler and scope-planner changes move source-delta dependency declarations into the typed manifest. Health 83 is wired to run for completed immutable campaign plans in addition to its weekly schedule. Added JavaScript and Python tests cover immutable evidence validation, duplicate/mismatch rejection, campaign evidence merging, merge-contract behavior, manifest compilation, scope planning, and workflow delivery contracts. The implementation is substantial but structured around explicit schemas/contracts and fail-closed validation, with no material acceptance-criteria gap evident from the diff.

anthropic

  • Model: claude-sonnet-5

    • Risks: 7.0/10
  • Summary: The PR introduces a substantial, well-structured set of changes aimed at hardening the fleet delivery sync/merge process: new buildNoChangeEvidence/mergeCampaignNoChangeEvidence functions that bind no-change delivery results to exact plan identity, scope, source commit, and head SHA (failing closed on mismatches or duplicates), rewrites to maint71_merge_sync_prs.js and sync_pr_merge_contract.js that appear to address reviewer settlement, fail-closed checks, and missing-PR handling, manifest/schema updates to declare source-delta dependencies, and corresponding workflow YAML updates for Health 83 and Maint 71/68/82. Test coverage is extensive and directly targets the acceptance criteria (new JS tests for no-change evidence binding and merging, expanded sync_pr_merge_contract tests, Python tests for manifest compiler and scope planner). All CI suites reported (pr-11-ci-smoke, selftest-ci) succeeded, and pr-00-gate showed no failures. Based on the available diff and test evidence, the implementation appears to functionally satisfy the stated acceptance criteria, though the truncated diff limited full line-by-line verification of every edge case.
  • Concerns:
    • Full diff was truncated in review, so some implementation details (e.g., reviewer settlement logic in sync_pr_merge_contract.js, maint71 continuation state machine) could not be fully traced line-by-line.
    • The scale of changes to maint71_merge_sync_prs.js (+335/-69) and sync_pr_merge_contract.js (+229/-34) indicates significant behavioral rewrites; without full visibility, subtle edge cases (e.g., race conditions in plan-bound continuation state) can't be fully ruled out.
    • pr-00-gate.yml workflow was still in_progress at time of review (1 job pending) though this is explicitly out of scope for this post-merge verification per instructions.
