How can I continue?After more reviews become available, a review can be triggered using the 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.

📝 WalkthroughWalkthroughThis 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. ChangesSync orchestration
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to 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.

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.
