memory: snapshot — althing 3.2.1 deployed; guard 4 cannot cover two of five seats

3.2.0 wrote its pokes into pane input lines and pressed Enter, so anyone
mid-sentence had their half-written message submitted with the herald's
line stapled on. It hit the operator within an hour of this evening's
deploy. 3.2.1 adds a fourth guard that pins the pane's idle cursor column
and stays silent when the live column has moved.

Deployed all three steps at 22:40 and re-declared this seat, which pinned
idle_cursor=3 as expected for a claude TUI.

The finding worth keeping is the hole the fix leaves. forseti's own
measurements say kimi and pi report no cursor at all, which means
bil-smithy-dev and regin-smithy-dev can never acquire guard 4 no matter
what they run. Two of the five pane seats on this box stay permanently
exposed to the bug 3.2.1 fixes, so the sentence "3.2.1 fixes the
write-into-a-typing-pane bug" is only true where the cursor is legible.
All four seats were told, differentiated: a pre-filled re-declare and the
expected column for the two that can be guarded, and the honest version
plus the release-to-pull-only option for the two that cannot.

Also keeping forseti's post-mortem line, because it generalises: three
guards that all answer "is this the right pane" and none that asks
whether it is a good moment are one check wearing three hats.
