## ship 内容 (Step 3 iii design fix)

before (post Step 1+2):
```js
} catch (err) {
  log(`HANDSHAKE processing failed for ...: ${err?.message}`);
  markSeen(txId);   // ← sticky-seen 让 root cause invisible
}
```

after (Step 3 iii):
```js
} catch (err) {
  log(`HANDSHAKE processing failed for ...: ${err?.message}`);
  // T1-bugfix-handshake Step 3 (iii) design fix per NWT r130: NOT markSeen on silent throw — catch-up retries next cycle.
  // Step 2 telemetry will isolate the failing step within 1-2 catch-up cycles.
  // Risk mitigation: if throw is deterministic, infinite retry — revert + add retry-counter cap if observed.
}
```

净 +3 comment / -1 markSeen line.

## architectural rationale

silent catch markSeen → handshake txid sticky-seen across restart → catch-up skip → root cause invisible. (iii) design fix:
- 删 markSeen on silent throw → catch-up retry next 30s cycle
- Step 2 telemetry (Step 1+2 已 ship) isolates failing step within 1-2 cycle
- 修 root cause cleanly vs (i) one-shot del txid OR (ii) del entire seen.json side-effect risk

(iii) + (i) hybrid (per NWT r130):
- (iii) J2 implementor ship 完毕 (本 commit) — 永久修 sticky pattern
- (i) NWT operator hat parallel 删 specific txid (10:55:45 stuck handshake) from kasia-relay/state/seen.json — unstuck pre-fix sticky txid (新 (iii) 不 cover already-stuck)

## risk mitigation (per design fix comment)

deterministic throw → infinite retry possibility:
- mitigation: post-fix 1-2 cycle 内 verify (Step 2 telemetry 帮 isolate)
- 若 deterministic infinite retry observed → revert (iii) + 加 retry-counter cap (e.g. _attempted Map: tx → count, count > 3 mark seen)

## acknowledged invariants

- Bug 1 在 rpc-listener.mjs 不动 matcher.mjs (per Anti-pattern #3) ✓
- 不 try/catch 绕过根因 (per Anti-pattern #1, (iii) 是修根因 not 绕过) ✓
- step telemetry 配套 ship (per Anti-pattern #5, Step 2 上 commit 已 ship) ✓
- 戒"真"字 (Owner 5-1 严训, diff additions grep filter = 0 hit) ✓
- 5 轴 layered protection (J2 implementor scope ship, NWT operator hat parallel restart + cleanup)

## breaks invariants: NONE

## Tests

- node --check ✓ syntax OK
- node scripts/lint-kanet.mjs ✓ 1 file clean
- pre-commit hook lint-kanet ✓ commit gate pass
- diff additions 戒规则 grep filter = 0 hit ✓

## NWT operator hat parallel 待动作

per NWT r130 verdict — operator hat 同期:
1. (i) cleanup specific stuck txid (10:55:45 handshake from nurg → Trader-M) from `kasia-relay/state/seen.json` — OR delete entire seen.json fallback
2. path (A) /relays/:id/assign reassign same adapter (My-Brain-Qwen3) — leverage existing endpoint trigger startRelay (line 116). 如 (A) 不 stop+start cycle → fallback (B) manual kill + reassign
3. wait catch-up 30s cycle
4. tail console.log 看 outer catch err message: `HANDSHAKE processing failed for nurgcqs3s588: <err.message>`
5. broadcast 触发器 NWT verdict (架 architect hat for Step 4 根因 fix)

## J2 standby

post (iii) ship → 等 NWT operator hat broadcast Step 3d tail err → J2 implementor 触发器 #4 propose Step 4 根因修 (per err.message → fix path: fetch failed / storage_mass / etc)

## Acceptance status (post Step 3 iii ship)
