Architect drift review (d50a482..feat): drift_found — documentation only, NO contract violation. C1/C9/C10/C23 verified preserved against the diff: `generalization` is a pure deterministic fold (registry-side, C9; R-only, C10); the sole `instrument = Some` production site is `run_generalize`, every other manifest constructor threads `None` + `skip_serializing_if`, so sweep/mc/walkforward/standalone manifest bytes are byte-identical (C23); the compat read-mirror was threaded in lockstep. Drift fixed in this commit (ledger sync, docs/design/INDEX.md): - The inferential-honesty thread read "now two of three pieces built" / "#146 remains the last open piece" — false now that #146 landed. Updated to record the inferential half as structurally complete (all three built, cycle 0078) + the #146 realization, including the aggregator/validator-vs-selector distinction (#146 is a recomputable aggregate, not a FamilySelection annotation). - C18 realization block: added the cycle-0078 note — the comparison axis (C12) realized as FamilyKind::CrossInstrument + the first-class RunManifest.instrument lineage field. Regression: no regression scripts configured (project facts name only Build/Test/Lint/Doc); architect is the gate. cargo test --workspace green (0 failed) and cargo clippy --workspace --all-targets -D warnings clean, orchestrator-verified. Ephemera removed per the project lifecycle convention: docs/specs/0078-* and docs/plans/0078-* (git rm). Durable rationale lifted to the ledger above. refs #146
