audit: cycle 0040 — drift-clean (wiring-totality check)
Close-audit for cycle 0040 (commit range b6174cf..227d004). Architect drift review against the design ledger + CLAUDE.md domain invariants: no contract drift, no debt. - C23 intact: check_ports_connected is index-based and pre-build, reads only signature().inputs.len() + the existing raw-index Edge/Target, and emits nothing into FlatGraph. Lowering pushes leaf-recipe signatures (not derive_signature's output); composites inline away; the run loop is untouched. - derive_signature/interior_slot_kind bounds-totality weakens no validation: the placeholder kind for a structurally-invalid composite is consumed only by the parent's speculative kind-check, while the recursion independently re-rejects the same out-of-range index via the guarded BadInteriorIndex/OutputPortOutOfRange loops. The change converts a panic into a deferred-but-still-reported error. - The C8 cycle-0040 realization note accurately records the new invariant, scopes it to interior slots, names open roles as providers, and does not re-claim the dropped swap-closure goal or overstate name load-bearingness. - No legal graph is newly rejected (open source:None roles excluded as providers; root-open stays governed by UnboundRootRole). Regression gate: no regression script declared in project facts -> architect is the sole gate (drift-clean). cargo test --workspace 231 passed / 0 failed; cargo clippy --workspace --all-targets -- -D warnings clean (independently re-run by the orchestrator). refs #65
