Architect drift review over 9c6b9c7..cb32658 returned drift_found (3 items); all resolved here. What holds (architect): C23 default-argmax byte-identical, C9 separation (selector in aura-registry, walk_forward selection-agnostic), C1/C2 (plateau pure/deterministic/in-sample), one higher_is_better direction source. Resolutions: - [medium] Backfilled the pre-0077 FamilySelection legacy-load fixture (report.rs family_selection_loads_a_pre_0077_legacy_line). The feat commit and the struct doc-comment claimed "a legacy line still loads (C14/C18)" as landed, but no test pinned the field-level mapping: bare deflation scalars -> Some(...), absent plateau keys -> None. families.jsonl/runs.jsonl are append-only, so a winner stamped pre-0077 must read back; now pinned. - [low] Synced the ledger's inferential-validation open thread (docs/design/INDEX.md): #145 plateau-over-peak landed (cycle 0077), selection is now a pluggable objective (bare argmax -> trials-deflated -> plateau) on the manifest carrier; only #146 (cross-instrument generalization) remains of the milestone's three pieces. - [medium-high] Removed the cycle ephemera (git rm docs/specs/0077-*, docs/plans/0077-*) per the cycle-close convention. Regression: full workspace suite green and clippy --all-targets -D warnings clean (verified at feat-review time). No baseline scripts configured; the test + clippy gates are the regression gate. Cycle 0077 tidy (clean) — drift-clean, not a milestone close (the milestone fieldtest is a separate deliberate gate).
