The cooldown key was customerID:eventType plus the tier and run suffixes, and none of them names an app, so every app going down inside the same hour collapsed onto one key and only the first was mailed. Measured on demo-hp: bookstack sent 09:27:51, privatebin suppressed 09:31:51 under key=demo-hp:app_start_failed. cooldownStackSuffix is the third sibling of cooldownTierSuffix and cooldownRunSuffix, and separate for the reason the second one's docstring already gives: the existing two keep byte-identical semantics for every type that uses them. It is ALLOW-LISTED to app_start_failed and takes the event type as well as the details, unlike its siblings, and that asymmetry is the safety property. The backup family's cooldown is coarse ON PURPOSE (R-97a, R-182) so one full disk sends one digest rather than one mail per app - and crossdrive_failed is severity error, reaches the operator leg, and carries stack_name through a DIFFERENT struct, so a payload-shape rule would have split it silently. The hour itself does not change. Gate 11 refuses a push whose REPORT.md carries an observation with neither `FILED: R-NNN` nor `NOT-A-FINDING: <reason>`. It deliberately does NOT accept a passing mention of some other R-number: the lost item cited R-182 as an analogy, so "cites a register row" would have passed the very item the gate exists to catch. That discrepancy with the spec is recorded in the gate's docstring. Registered here and in the controller and agent runners. NOT in the catalog runner - it has no shared-gate mechanism and appends --all to every gate; filed as R-391 rather than left as a sentence, which is this session's lesson. PROMPT-TEMPLATE.md §15.9 corrected: "documented, NOT acted on" was the wording that invited the gap, and it now names the markers and points at the gate. R-390 filed for the golden-bake runbook's missing `pveam update`. Hub tests 709 -> 716.
