Architect drift review over 3de00e2..HEAD (the 0049 spec/plan/feat plus the
two intervening refactors that had not been audited: aura-ingest M1 transpose
6390093, aura-std SMA perf 67c1f51). Verdict: feature clean — C1 determinism
preserved (RandomSpace points seed-determined before any run; grid path
behaviour-preserving via trait-forwards-to-inherent), the #52/#71 source-seam
firewall honoured in code (sweep stays &S: Space + Fn(&[Cell]) -> RunReport, no
Source type enters the sweep layer; SplitMix64 a code-path-disjoint instance),
and both intervening refactors behaviour-preserving (pinned by
incremental_matches_full_resum_within_tolerance and
chunked_accumulation_equals_single_transpose).
Two low-grade doc-debt items found and fixed inline (doc-only, behaviour-
preserving):
- sweep.rs module doc named only the grid axis; refreshed to name RandomSpace
+ the Space trait the module now also owns.
- C12 ledger had no realization note for axis-1 (param-sweep); added one
recording the grid (0028) + random (0049) landing and the Space-trait
unification.
Regression gate: the project configures no regression scripts, so the test
suite + lint are the gate. Independently verified: cargo test --workspace green
(incl. the 17 new engine tests + 6 public-API E2E), cargo clippy --workspace
--all-targets -- -D warnings clean.
Drift-clean, not a milestone close (no milestone fieldtest run this cycle).
