I read this as implementation - I’ll inspect the current evidence layout and candidate tooling, then build the private TDD harness and complete the requested read-only verification without touching live lifecycle state.


The current v4 runbook confirms G13 is genuinely absent and defines three distinct authority files. I’m now binding the replacement to their actual candidate schemas and write patterns so it validates transitions rather than merely reporting filesystem activity.


Schema and write behavior are now pinned: outbox and activation audit use atomic replacement; the scheduled ledger is append-only, while the lifecycle’s exactly-once customer delivery authority is the atomic `draft-deliveries.json` map. I’m implementing against those exact boundaries, with descriptor-safe reads and readiness-FD handshakes in tests rather than timing delays.


Implementation is complete enough for the single disciplined test execution. I’m entering verification now: one pytest run, then Ruff/LSP/compile and a live read-only arm-only invocation only if the suite is clean.


I read this as implementation - the private lifecycle observer harness is built, sealed, and independently validated.
