Architect drift review (c192dfd..a295905): drift_found, medium/low only — no
ledger or hot-path contract crossed. C23-additive, C1-deterministic, C14/C18
back-compat all verified green (full workspace suite + clippy). No regression
scripts configured (test+clippy are the gate).
Resolution:
- [medium] three spec-promised optimize_deflated tests were missing (the
centring control, the all-noise high-p companion, the C2 IS-only read) — the
centring was unprotected ("removing it would pass every test"). Plus an
unguarded dispersion-floor sign assumption. FIXED in 0076.tidy (ecc9541).
- [low, RATIFY] the ledger's "Open architectural threads" inferential entry was
stale on one fact (it described optimize as having no trials penalty). Synced:
it now records that #144's trials-deflation landed this cycle (additive
optimize_deflated, winner unchanged — C23; optimize/rank_by stay bare argmax),
that #139's per-candidate OOS bootstrap landed in 0075, and that #145/#146
remain open. This ratifies the cycle-0076 intent; the gap description is
preserved for the still-open default-ranker path.
Deferred (spec 0076 Out of scope, not drift): n_eff effective-trials advisory,
reload-time recompute of the R-arm statistic, deflated-score re-ranking, CLI
flags for the resampling config.
Ephemeral spec + plan (docs/specs/0076-*, docs/plans/0076-*) removed per the
cycle-close convention. refs #144
