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.

WalkthroughThe change adds parsing and expiry classification for dependency bypass annotations. Conformance checks now reject missing, malformed, or expired annotations. Workspace entries include review or permanent markers, and contributor documentation describes the required bypass procedure. ChangesDependency bypass expiry enforcement
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟡 Moderate · up to This PR adds review dates and expiry enforcement for dependency bypasses, but the current gate can silently stop policing a bypass list if its block is renamed or moved, and malformed entries can produce misleading failures; the runbook also prescribes an override form that conflicts with established single-floor usage. These are actionable merge-readiness risks that should be fixed or explicitly accepted before merge. Sequence Diagram(s)sequenceDiagram

match()retains only the first occurrence of each marker type, so a block with twobestax:reviewmarkers is accepted. If someone adds a new future marker above an old due marker instead of replacing it, the gate silently ignores the contradictory expiry despite the one-annotation contract. Count all marker occurrences, reject totals other than one, and cover duplicate review/permanent markers in the tests.

const permanent = text.match(PERMANENT);

- This instruction should require a version-qualified exclusion. Excluding the bare package disables the cooldown for every release until the review date; combined with the range override above, a later lockfile refresh can admit a newer, unreviewed release published inside the 72-hour window. Add only the known patched release to
minimumReleaseAgeExclude.

Verified on the real file again: stacking a second Worth noting for whoever merges: every finding across all four review rounds has been a fail-open in code whose entire purpose is to fail closed. That is a fair signal this check earned the scrutiny, and the reason each fix ships with a regression test naming the exact silent behaviour it prevents. |

- Around line 75-82: Update step 1 in the override guidance to cover advisories
with one patched floor across multiple affected majors: use an unbounded-lower
selector such as the existing postcss or sharp patterns instead of narrowing the
override to the currently observed major, while retaining major-scoped selectors
when majors have distinct backports.
In `@pnpm-workspace.yaml`:
- Around line 57-64: Reword the review marker immediately above
serialize-javascript so it clearly applies only to that override, rather than
implying coverage of subsequent entries. Preserve the quarterly-sweep context
while explicitly identifying serialize-javascript as the reviewed entry, and do
not change the dependency constraint.

- Around line 1184-1192: Update the conformance check around BYPASS_BLOCKS

empty. Preserve the existing fail-open protections in the parser, and require
legitimately removed blocks to also be removed explicitly from BYPASS_BLOCKS.

- Around line 210-221: In the unparsed-entry branch of the entry-processing

- This lower bound makes the test fail after four valid bypasses are pruned, even though pruning them is the workflow this change is meant to enforce. Keep only a nonzero guard here (or assert the expected
blocksSeenkeys separately) so the test detects a parser matching nothing without baking existing dependency debt into the suite.

Two suppressed review comments, both real.
overrides is a YAML mapping, so its empty form is {} — the empty-block path
only accepted [], which is an empty sequence and the wrong collection type.
Pruning the last override to the correct {} was reported as a missing block,
and the diagnostic then told the maintainer to write the wrong YAML. Each
block now declares its own empty literal, the message quotes it, and a test
asserts every literal matches the pattern that accepts it.
SECURITY.md still described cooldown exceptions as carrying an inline
rationale and a removal date, which contradicts the contract this PR
introduces: the marker goes in the comment above the entry, covers all three
bypass lists, and the date is a review-by rather than a removal deadline.

Both suppressed comments from the last pass applied in c2b6d5d — thanks, the
SECURITY.md contradiction. Also right, and worth more than a doc tidy: it described cooldown exceptions as carrying "an inline rationale and a removal date", which conflicts with this PR on three counts — the marker goes in the comment above the entry rather than inline, it now covers all three bypass lists rather than just the cooldown exclusions, and the date is explicitly a review-by rather than a removal deadline. CONTRIBUTING links that guide directly above the new runbook, so a contributor would have hit both versions in one sitting.

YAML block sequences may be indentless: items sit at their key's own indentation rather than deeper. The dedent test read the first such item as a sibling key and ended the block, so BOTH list-valued bypass lists dropped out of the parse entirely — no entries, no problems recorded, and blocksSeen still holding both headers, which left the gate green with every cooldown exclusion and audit ignore unpoliced. Blocks now declare whether they are list- or mapping-valued. A sequence item at the header's own indentation continues a list block; anything else at that indentation still ends it, so a sibling list like publicHoistPattern is never absorbed and a mapping block like overrides is unaffected. Both directions are pinned, including the mapping case.

- The
>= 15assertion hardcodes today's bypass count. Once enough temporary entries are pruned—the intended remediation—this test fails even though all three blocks may legitimately be empty and the parser explicitly supports that state. Assert that everyBYPASS_BLOCKSkey was seen instead; this still catches a silent parser miss without requiring bypass debt to remain.
// A parser that silently matched nothing would pass every assertion below.
assert.ok(entries.length >= 15, `parsed only ${entries.length} entries`);
The guard asserted at least 15 parsed entries, which hardcoded today's bypass debt: pruning entries — the entire point of this gate — would have failed the suite, and the parser explicitly supports all three blocks standing empty. It now asserts every BYPASS_BLOCKS key was found, which still catches a parser that silently matched nothing without requiring the debt to stay.

Implements D + E from #391.
The problem
pnpm audit --audit-level=highis a blocking gate;minimumReleaseAge: 4320refuses anything published in the last 72 hours. When an advisory's only patch is younger than that, the two rules demand opposite things and every open PR goes red over a transitive dependency nobody touched. The escape hatch (force the version inoverrides, waive the cooldown for it) worked but was undocumented and permanent by default — nothing made the expiry observable, so entries outlived their own stated reason.D — the runbook
CONTRIBUTING.mdgains the actual procedure: force the patched version scoped to its major, add the cooldown exclusion if the patch is still inside 72h, annotate both with a review date, confirm the audit is clean, commit the lockfile. It also says plainly that a red gate from this cause is not your PR's fault, and thatpnpm alldoes not run the conformance checks (CI does).pnpm-workspace.yamlstates the contract at the top, where someone editing it will see it, andCLAUDE.mdcarries the rule so other sessions inherit it.E — the gate

The missing-annotation half is what gives it teeth — without it a new bypass just omits the marker and the check is decorative.

The repo declares no YAML parser anywhere, and adding one to police the cooldown would itself be subject to the cooldown.Existing entries are dated 2026-11-13 — all reviewed today, one quarterly sweep rather than invented staggered dates. Expired entries in a list report as one grouped violation, so a batch coming due is a single chore.
