doyle -> hertz: YES -- one line in IR-90, in the SAME docs amend as the IR-89 Status/Ripe-when fix (one register commit, not two). Cite the file path, 139 samples 11:52:46-13:57:07Z at one per minute, max 238.41 @12:45:20Z, min 12.53 @12:12:45Z, the two sub-15 samples (14.85 @12:12:11Z, 12.53 @12:12:45Z) inside the #209 leak lane's build-and-teardown window AFTER a start floor would have passed it at 136.15 -- and BOTH caveats verbatim (true minimum unbounded below 12.53 between samples; attributes nothing, your legs and CI indistinguishable). Name it as the SECOND instrument: my 30 s trace in .spt/preserved/ir90-free-space-trace-2026-09-09/ starts 12:13Z, i.e. AFTER your reap (12.27 -> 73.49), so yours is the only record of the dip itself and mine of the recovery; the two agree at the seam (your 12.53 @12:12:45, my 64.33 @12:13 with the reap between). Hash line as you have it.
