Cycle-close audit (architect: drift_found, design core clean). What holds,
architect-confirmed: C18 bit-identity for RunMetrics (prose derived
byte-identically, rng order preserved, registry suite unchanged); the C10
wall (monomorphic R-gates, r_based in the R vocabulary, cross-vocabulary
refusal tested both ways — no leak); C28 direction (trait in aura-analysis,
vocabulary supplied from the outer rungs, zero Cargo edge changes); C1
determinism pinned through the generic path.
Drift items, all resolved as fixes in this commit:
- design ledger: the C28 #147 disposition now records item 2 SHIPPED (the
A1 cut) with A2 still deliberately deferred; the #136 one-implementor
clause carries a supersession note (the IC is the second implementor).
- seven stale doc comments describing the pre-#147 or mid-cycle state
(analysis trait + estimator docs, registry check_r_metric C9 claim,
engine re-export note, campaign PER_MEMBER_METRICS roster note,
member-seam guard comment, research vocabulary note) updated to the
shipped state.
- R_BASED_METRICS is now oracle-pinned against RunMetricKey::r_based()
in the vocabulary test (it feeds the NonRMetric refusal prose; a
divergence would have misreported the R-gate silently).
Noted, not amended (history stays): commit 6744f67's body says 'three
syntax-only edits' where the test module actually took five.
No regression scripts are configured (the bench is report-only); the
architect review is the gate. Verification: extended vocabulary test,
campaign suites, analysis/research suites green; clippy --workspace
-D warnings clean.
