Issue 24503 — final evidence capture
Captured UTC: 2026-10-24T20:35:36.365058+00:00
Scope: sandbox repro thread only; SQLite opened mode=ro with query_only=ON.
Original runtime-before.txt, runtime-after.txt, red-test.txt left unchanged.
Pre-restart historical state comes from lead runtime-after.txt; current DB cannot independently reconstruct an earlier projection.
Fixture matrix rows: 0/0 (server-only diff; no render changes).
No server/browser started; no source edits, commits, pushes, or merges.

ASSERTIONS
PASS: pre-restart ordinal2 completed and owned command running
PASS: after restart original command cancelled
PASS: source cancellation note preserves exact command ownership and wake
PASS: exactly one continuation references ordinal2, and is ordinal3
PASS: synthetic restart note delivered as ordinal3 user message
PASS: provider acknowledges restart and waiting
PASS: continuation actually launches sleep 180
Current ordinal3 status: running
Delivery is proven by persisted provider acknowledgement; no wait for sleep completion required.

PRE-RESTART CAPTURE (verbatim from original runtime-after.txt)
After fix ae08fca637; real app Codex gpt-6-astra, same sleep 180 short-yield prompt.
Pre-restart persisted state:
