Architect drift review (8d04a84..HEAD): clean, no drift/debt. What holds (verified against code, not asserted): - C10 cost contract preserved: the non-R-harness guard reads the *resolved* harness, so a `run` cost flag on sma/macd (incl. the implicit default) is exit-2 fail-loud, never a silent no-op; parse_nonneg_rate names the flag; the eight stage1-r cost goldens are byte-unchanged. - The three edited realization notes are grounded: C12 Arc-sharing → aura-ingest/src/lib.rs:316; aura-std "~30 modules" → 30 node files; C15 Session emits only bars_since_open, matching the quoted source wording. - project-layout.md rewrite complete: no residual exposure/realistic-broker. Non-actionable scaling note (architect): the guard hardcodes Stage1R as the sole R-harness, coupled to the "stage1-r only" note text — three sites move together if a second R-harness ever lands; not in plausible next scope. Regression gate: cargo test --workspace exit 0 (48 binaries, 737 passed, 0 failed); cargo clippy --workspace --all-targets -- -D warnings exit 0. No baseline moved → no ratify needed. cycle 0086 tidy (clean). Ephemeral spec/plan (docs/specs/0086, docs/plans/0086) removed per the ephemeral-artifact convention.
