Architect audit clean (no drift, no debt): raw sqn verified bit-identical, C18 serde back-compat + C4 SoA seam + C1 determinism + Part-B symmetry all hold. - Ledger C10: add a "Realization (cycle 0067, #130 + #135)" note — SQN100 as the turnover-robust opt-in rank key (raw sqn / default ranker byte-unchanged, serde(default) for back-compat), and per-member --trace now symmetric across all three sweep strategies via the shared persist_traces_r. - Glossary: R-metrics list gains sqn_normalized; the SQN entry documents the SQN100 variant (was "deferred #130"). - Remove the ephemeral spec + plan (cycle closed; rationale lives in the ledger and git history). refs #130, refs #135
