Record F33, the launch that confirmed itself in seven milliseconds

Run 5's first attempt never started: ConfirmInput's first poll beat the TUI's
render, saw an empty editor and called it editor_cleared. The prompt sat unsent
while the lease renewed against a pane doing nothing.

Recovery is left to lease expiry rather than a keystroke, so the relaunch stays
autonomous evidence.

+## Run 5, first attempt: the launch never went off, 2026-08-28
+
+Filed as `kami/test-e2e#5`, ingested as `06G4A4F0TFXKZHJE48N05XN1HG`, placed on
+`workpc-claude` by normal routing. Issue filed to confirmed launch: 44 seconds.
+
+Then nothing moved for seven minutes. The pane held the launch text unsent:
+
+```text
+❯ @.orchestra/launch.md is your complete Orchestra launch instruction. Read
+  .orchestra/launch.md now and follow it.
+
+0 tokens        ⏱️ 0m 0s        session ... - none

+
+### F33: an editor that never rendered confirmed the submit
+
+```text
+first_submit_at  21:13:19.570302125Z
+confirmed_at     21:13:19.577191672Z
+confirmation     editor_cleared   submit_attempts=1
+```
+
+Seven milliseconds. `ConfirmInput`'s first poll ran before the TUI rendered the
+pasted text, found an empty editor, fell through to the idle branch, and called
+that proof of submission.
+
+The two launches that worked earlier took `submit_attempts=2` over roughly
+500ms. The difference between a good launch and this one was scheduling luck,
+which is why it had never been seen before.
+
+The cost is worse than a failed launch. The coordinator believes the agent is
+working, so the lease renews against a pane that will never produce anything,
+and the failure only surfaces at expiry half an hour later.
+
+Fixed in `32220d9`. An empty editor counts as proof only after it has held the
+text, or after it has stayed empty past a settle window. Text seen and then
+gone still confirms immediately, and so do `busy`, `blocked` and `queued`. With
+the fix the failing case reaches the existing resubmit path instead: the text
+appears, is recognised as unsubmitted, and Enter is resent.
+
+### Recovery, deliberately not by hand
+
+Pressing Enter in the pane would fix this run and prove nothing. The lease is
+left to expire and relaunch on its own, which is the autonomous path run 3
+already proved. The worker carrying `32220d9` is deployed first, so the
+relaunch uses the fixed confirmation.
