Inline comments:
In `@src/domain/helpers/isCanonicalCollectionKey.js`:
- Around line 21-35: Confirm the project’s engines or minimum Node target
supports String.prototype.isWellFormed() (Node 20+), then replace the manual
isWellFormed loop with the native String.prototype.isWellFormed() call while
preserving the existing boolean validation behavior.
In `@src/domain/services/ExpiringSet.js`:
- Around line 308-338: Collapse the duplicate witness construction in
`#markerWitness` and `#indexWitness` into a single shared helper, preserving the
existing RetentionWitness fields and root metadata. Update both call sites to
use the shared helper while retaining their current argument semantics, so the
marker and index paths cannot diverge.
In `@src/domain/services/ExpiringSetMetadataCodec.js`:
- Around line 55-81: Update normalizeState to validate that state.updatedAt is
not earlier than state.createdAt, alongside the existing timestamp and
nextExpiry checks. Reject inconsistent states using the established invalid
validation path, while preserving all existing count and expiry invariants.
In `@src/domain/value-objects/ExpiringMarker.js`:
- Around line 30-38: In the ExpiringMarker construction flow, guard evidence for
null or undefined before the RetentionWitness normalization branch. Throw
invalid(...) using the existing EXPIRING_SET_MARKER_INVALID path, and only
instantiate RetentionWitness for non-nullish evidence while preserving existing
RetentionWitness instances.
In `@test/unit/domain/services/ExpiringSetMetadataCodec.test.js`:
- Around line 35-64: Add a direct assertion in the “ExpiringSet metadata
rejection” test that codec.encodeMarker rejects a marker whose
verificationDigest equals marker.keyDigest, expecting
EXPIRING_SET_MARKER_INVALID. Keep the existing non-canonical marker and
state-count assertions unchanged.
In `@test/unit/domain/value-objects/CacheCollectionValues.test.js`:
- Around line 42-44: Add a lone-surrogate rejection assertion alongside the
existing ExpiringSetKey combining-character test, using the same
EXPIRING_SET_KEY_INVALID error expectation. Keep the current valid-key assertion
and Unicode normalization coverage unchanged.

Learning: In fuzz tests for cryptographic operations, use a seeded PRNG (e.g., xorshift32) for control-flow variables such as plaintext size selection and recipient index selection to ensure reproducibility. Continue to use randomBytes() for cryptographic keys and nonces to preserve realistic randomness and avoid security anti-patterns. This guideline applies to test files that perform fuzz testing of crypto logic; implement a consistent seed setup (e.g., fixed seed in test initialization) and document the rationale to enable deterministic replays across runs.

Learning: In this repo, CHANGELOG.md entries should be user-facing and descriptive (bullet points) rather than cycle-ID headings (e.g., use a phrase like “Planning-index consistency review” instead of a “TR-010 — …” heading). When searching the changelog, don’t rely on grepping for cycle IDs (e.g., “TR-010”) because it may cause false negatives; search for the descriptive keywords/phrases from the bullet entries instead.

Learning: In git-stunts/git-cas, the codebase is intended to run on multiple JavaScript runtimes (Node, Bun, and Deno), not just Node. During code review, don’t suggest replacing existing portable helper logic with newer Node-only built-ins (e.g., Node 20+ APIs like `String.prototype.isWellFormed()`) unless the change preserves Bun/Deno compatibility (via portable/polyfill implementations or safe runtime gating). If a file includes manual implementations (such as `src/domain/helpers/isCanonicalCollectionKey.js`), treat them as intentional to avoid requiring a higher host built-in baseline.

Summary
cas.expiringSets.open()with atomicaddIfAbsent, targetedcontains, expiry-onlysweep, boundedinspect, and non-mutatingdoctorrefs/cas/expiring/*Why
Security-sensitive replay markers must survive process restart and Git garbage collection for their entire acceptance window. Application code should not manage CAS objects, trees, refs, or an independent cache to get that behavior.
ExpiringSet deliberately has no live
remove,repair, capacity, or LRU path. Release means publishing a parentless generation that no longer reaches expired support; this API never deletes objects or runs Git GC.Linked Issues
Closes #53
