…gs across the stack
## What
Serial application of the triaged APPLY verdicts from the 18 Copilot reviews across the stack — 25 threads in total: 16 applied here, 2 rejected as replicated quirks citing the ledger (`CLOJURE_QUIRKS.md`), 3 declined, 1 deferred.
## Highlights
- Improved-mode early returns no longer leak stale `group_clusterings`/`group_k_smoother` across engine-mode switches (flipping a conversation between clojure-legacy and improved mode) — TDD with the failure observed RED first.
- The certify cache manifest now hashes comments CSVs (with the required one-time Clojure re-record of the 3 moderation battery entries, done).
- `lru_cache` on tree hashes.
- Battery-entry dataset-mismatch guard.
- Slug-glob sanitization.
- The quirk-Q11 clamp now propagates NaN (Q11: the Clojure k-means distance formula's cancellation floor — the clamp must floor only negative cancellation residue to 0.0, never mask NaN).
- Quirk-Q16 comment projection is always 2-wide (Q16: rank-1 principal components collapse all projections to [0,0]).
- Shard-bench file-descriptor/kill cleanup.
- Docstring + test hardening.
## Re-certified
Certification battery 20/20 MATCH x2 on this tree (`battery_s6_pass{1,2}.log`); the 647-test combined gate green.
