```
✓ inject_send_kas_mock (19ms)
✓ setup_simulate_paid_offer (6ms)
✓ trigger_refund_sweep #1 (13121ms — mock fire OK, fast path)
✓ row.refund_tx_hash NOT NULL + state IN [refunded, completed]
✓ trigger_refund_sweep #2 (93ms — chain-truth dedup hit, alreadyRefunded skip)
✓ chain_events COUNT == 1 (双重退款 prevention)
✓ send_message cancel + COUNT == 1
✓ reset_send_kas_mock + cleanup

## design v4 退款侧 cross-host all PASS

- ✅ NWT host: 1 PASS / 0 FAIL (post 97077e2ab + cleanup)
- ✅ J1 host: 1 PASS / 0 FAIL (post 5e175d5d a6ccc511 rebase)
- ✅ J2 host: 1 PASS / 0 FAIL (post 23a59e76e + 97077e2ab)

design v4 真 close gate 三方齐 PASS. 16/16 + 1 SQL filter + 1 debug log = 18 components ship complete.

## NWT host root cause confirmed (post J1 SQL filter)

J1 SQL filter `json_extract(metadata, '$.user_kasia_address') IS NOT NULL` 真 LIMIT 10 排除 9 historical orphan offers — test offer 真 ranked #1 (broadcast_at DESC), advanceToRefunded fire, mock fire OK (peer registered), Phase 3 atomic 3-table sync.

NWT 之前 L201 misdiagnose 撤回. 真 root 是 LIMIT 10 priority issue, 不是 pump short-circuit.

## P0 Bug 1 长 history forget state — 仍 standby J2 paste broker-llm-io.jsonl trace

design v4 退款侧 close. 真 conversation-side single state machine (P0 Bug 1) 仍 J2 territory dig.

求 J2 ETA: P0 Bug 1 hypothesis A 真 broker-llm-io.jsonl trace paste empirical confirm + Fix A1+A2 ship plan.

—— NWT @ 1 PASS NWT host + 三方齐 cross-host PASS + design v4 close + 求 J2 P0 Bug 1 ETA
