liam -> todlando, doyle (cc hertz). A3b IS UP. One write. Box is yours for the x3 fetch.
A3b-PRE  03:05:04.339Z  dump 566 ms, 687 rules, VALIDATION PASS: F 0, pair 2 (…-lan LocalSubnet, …-tcp 100.64.0.0/10), hand rule 1, installed exe 3 Allow 0 Block, subject exe 0/0, port-29470 rules 2.
  Listener check BEFORE: no LISTENING row on 29470. Your stop holds.
F RE-ADD 03:05:04.416Z: netsh add rule name="spt-w2-F" dir=in action=allow enable=yes profile=domain,private protocol=TCP localport=29470 remoteip=192.168.1.0/24 -> "Ok." exit=0. Byte-identical to the 02:51:36Z command.
A3b-POST 03:05:05.191Z  dump 622 ms, 688 rules, VALIDATION PASS: **F 1** (spt-w2-F | 29470 | remote 192.168.1.0/24 | prog '' | Allow | enabled Yes | Domain,Private), **pair 2** and unchanged, hand rule 1, controls unchanged, port-29470 rules 3.
  Listener check AFTER: still no LISTENING row on 29470. Daemon 39320 alive. Dialog scan: nothing. I started nothing.
THE STATE YOUR ARM NEEDS IS NOW EXACT: an ADMITTING rule present, listener DOWN, the product's non-admitting pair untouched beside it. So a SYN from kitsubito now reaches the stack and whatever the stack does is the product's refusal semantics rather than the LocalSubnet defect.
A4 PREMISE RE-ESTABLISHED AT THIS INSTANT, not carried from 02:56:35Z as I said I would not: the 03:05:04.339Z pre-dump above is the fresh baseline, and it differs from my stale one only by the listener now being down.
TABLE ROWS 11-12, both fast, +651 s and +652 s after hertz's transfer: 566 ms and 622 ms. Twelve rows; the decay reading still fits every one.
Doyle: your revised A4 prediction is noted and replaces the 03:03Z one in my read-out. I will report A4 against CLEAN-within-budget vs timed-out as discriminating ENUMERATION cost from FILTER-WALK cost, not elevation. My own 03:02:42Z filing stands unchanged in one respect only, and it is the one that does not depend on which way A4 goes: my census is what settles whether the rules actually left, the stderr is only the product's claim about that, and if the two disagree the dump wins and the disagreement is the finding.
Todlando: prediction 7 at ~2 s accepted as the face; I will not read a 2 s refusal as a deviation. Fetch when ready. I hold until your stamp for F-delete.
