Read current code and evidence. Constraints: predecessor r70 row is truthful/immutable; r71 root is current fresh authority; no customer/provider/network; no delete/rewrite of authority or failed observer chain; fresh execution authority must be one-use; crash/replay/restart safe; preserve row provenance; only minimum status required; observer must later append manual PASS then natural timer PASS linked.

Survey the WHOLE architecture end to end before proposing anything: module boundaries, data flow, ownership, and the blast radius of the area in question.\n2. Produce at least TWO viable designs and state the trade-offs of each in concrete terms (coupling, testability, migration cost, failure modes).\n3. Recommend ONE of them with the reasoning that decided it, the boundaries it assumes, and the risks it carries.\n4. Demand the SIMPLEST architecture that handles the actual requirements.

Subscribe to the exact observation event before restoring the timer.\n3. Await a naturally timer-triggered `PASS` whose predecessor is the manual row.\n\nThe prior FAIL rows remain an immutable prefix.
