Review rounds 3-5 remediations (Req 5, 7).
- ousast improve resolves candidates from the target's calibration dir,
then the working directory's (where `mechanisms export` writes), and
admits into <target>/.openultrasast/calibration/mechanisms.jsonl,
where a scan of that target reads; --mechanism-candidates,
--mechanism-store, --no-mechanisms; --dry-run redirects the store to
scratch; accepted rounds print admit/retract <id>.
- run_improvement threads the store paths; RoundOutcome carries the
mechanism edits; reverted mechanism keys are blocked outright; a
no-gain admission is rejected as mechanism_no_gain; a retraction may
name an admitted record that left the candidate set.
- leave-one-out forwards variant-search degradations and pins the
containment and label rules; mechanisms export defaults to the
candidates file so it never re-admits a tombstone.
- design §Lever rewritten to the implemented gate; README and docs show
export -> improve -> scan.

Task 4.2 (Req 5.3, 5.4, 5.5).
- propose_mechanism_edits: retract admitted records that leak on a
holdout fixed side; admit a candidate only when a trial store holding
it alone recovers a currently missed holdout pair without leaking.
- run_round(mechanism_candidates=, mechanism_store=): validates, applies
after the rule gate passed, re-scores the holdout pairs per profile with
variant search (evaluate_mechanism_profiles), and rejects with a
byte-for-byte revert on mechanism_leak, profile_regression or
mechanism_no_gain; the journal records each mechanism edit with its
pair provenance and the metrics before and after.
- The rule gate and its per-profile clause are unchanged.
