Warning Review limit reached
Next review available in: 21 minutes Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available. 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.

- Line 7: Reconcile the reviewed-code provenance in this evidence document:
update the SHA at the reviewed-code declaration and the references around the
trust bundle so every section binds to one consistent code SHA. If the later SHA
includes implementation changes, rerun the required reviews and record evidence
for that final SHA.
In
@.agent-loop/initiatives/WS-QUAL-001-backend-coverage-floor/reviews/WS-QUAL-001-01B1B-R10-pr-trust-bundle.md:
- Around line 31-34: Reconcile the reviewer-track count in the trust-bundle
summary with the internal-review evidence: either add the missing reviewer
result and run ID, or change “All ten required internal reviewer tracks” to the
evidenced count of nine. Keep the completion claim consistent before marking the
bundle complete.
In @.agent-loop/WORK_QUEUE.md:
- Around line 74-77: Update the next-action cells for WS-QUAL-001-01B1-R7,
WS-QUAL-001-01B1-R8, and WS-QUAL-001-01B1-R9 to state that each is superseded by
the reviewed R10 proposal and must not be repaired in place; preserve their
existing historical blocker reasons.
In `@backend/scripts/coverage_policy.py`:
- Around line 498-513: Update has_deleted_assertion to fail closed when
base_source is empty: after collecting deleted lines, return True whenever
deleted is non-empty and the provided base source is empty, before calling
analyze_python. Preserve the existing syntax-error and assertion-range behavior
for non-empty base sources.

WS-QUAL-001-01B1B-R10 PR Trust Bundle
Intent
Finish the semantic test-integrity gate without embedding a Python execution
model. The final policy is conservative syntax ownership: known pytest/unittest
weakening constructs are rejected and assertion deletion is protected.
Design
lexical ownership.
Python 3.12+ inlining, and Python 3.13 public TypeVar child ordering.
Scope
backend/scripts/coverage_policy.pybackend/tests/test_coverage_contract.pyThe 22-file final branch diff contains 1,906 additions and 39 deletions.
Only 577 raw lines belong to the policy/test implementation; the remainder is
the retained R1-R10 planning, stop, and review history. No CI workflow is enabled
here; B2 owns mandatory GitHub enforcement after this PR merges.
Verification
The identical 171-test matrix passes on Python 3.11.15, 3.12.3, and 3.13.3.
Ruff, dependency integrity, self-validation, exact scope, ancestry, wording,
memory, links, and diff hygiene pass. All ten required internal reviewer tracks
pass at
15d0b80e776f5be12cacc5dbe5226ffe3992dcfd.Risk And Human Focus
unrelated attributes, and non-TestCase
self.skipTestremain clean.selection, readable behavior matrix, and absence of CI/config/application
drift.
Follow-Up Gate
Stop after human review and merge. B2 remains inactive until this PR and its
post-merge memory are merged and the user explicitly starts B2. Coverage stays
at the measured 79.25 percent until B2 and coverage-raising chunks 02-06 run.
