// R-672 (v0.133.0): a thin pool crossing 90 % requests an out-of-band host report ONCE, through the
// watchdog's own read path (Known — every few seconds), so the hub's storage-fill alarm sees the pool in
// seconds, not at the next 15-minute report. Re-armed below 85 %.
//
// COMPANION RED-PROOF (REPORT): remove the noteThinFill call from the data path → "no report was
// requested when the pool crossed 90 %".
