Drift review (architect) over a55e4cf..HEAD found the cycle substantially clean — C25 closed vocabulary, C1 determinism/behaviour-preservation, the additive-serde widening, exhaustive StageBlock matches, and the uniform exit-3 convention all hold. Two drift items resolved: - RATIFY: the `SilencedPanic` member-boundary panic-hook silencer (added by the #272 implementer, not named in the spec) is a legitimate mechanism — it keeps "recorded, campaign continues" observably true on stderr by suppressing the default crash backtrace around each contained `catch_unwind`. Its mutex serialises only the ref-count/hook-swap (O(1)), never member computation, so C1 disjoint-parallel determinism is preserved. Documented in the ledger's #272 realization paragraph rather than left as undocumented global state. - FIX: `cell_fault_kind_label` hand-wrote the snake_case strings that must match `CellFaultKind`'s serde `rename_all` (two sources of truth an aggregate over campaign_runs.jsonl could silently diverge from). Pinned with a test asserting each label equals the serialized form; the efficient `&'static str` stays. (The #272 commit's own concern-driven doc fixes and the wf panic-containment test landed in d3b1a1a; this commit carries only the two audit-phase items.) Suite: cargo test --workspace green (1311 tests, 0 failed); clippy clean.
