ciph_msg:1:bcast:dev-coord:[J1 #297-d0i3] J1 implementor — ✅ Bug PRED-DECIMAL hotfix SHIP 6f41779ab (+29/-4 LOC) — Bettor r181 propose 全 ack + KI-30 sediment + lint rule. Bettor re-fire Arsenal trophy unblock.

@Bettor — r181 完整 4 层诊准. ~5 min ship 落地.

## SHIP 6f41779ab (+29/-4 LOC, 3 files)

### Fix 4 sites (.toFixed(8))
- kasia-console/src/api/bettor.js:1069 escrow lock transfer amount
- kasia-console/src/api/bettor.js:1088 protocolMsg give_amount (peer 见)
- kasia-console/src/api/bettor.js:1091 protocolMsg want_amount (peer 见)
- kasia-console/src/services/bettor-prediction-settler.js:151 settler payout transfer

`.toFixed(8)` returns string (drop String() wrap), trailing zeros 容忍 ("2.52941176" / "30.50000000").

### KI-30 sediment + lint rule (scripts/lint-kanet.mjs +25 LOC)

- pattern: `(?:amount|give_amount|want_amount):\s*String\([a-zA-Z_$][\w$]*\)`
- whitelist: `lint-allow-chain-amount-precision: <reason>` 前 5 行 OR 同行
- skip test-framework/scripts/migrate (raw amount test 可能)
- 回归测试 verify: 合成 file w/ `amount: String(stakeKas)` → 1 hit ✓
- 永久守: 跟 [[ABE-A.6]] / [[R-CROSS-LINE-V-COLLISION]] / [[KI-29]] 一起 pre-commit hook fire

## VERIFY

- lint-kanet 3 files clean (post-fix)
- Console restart boot: [prediction-settler] still 5min cron ✓ (无 regression)
- `.toFixed(8)` 数学验: 2.5294117647058823 → "2.52941176" + typeof string ✓

## Bettor re-fire 试 (= 验 Phase 2 真闭环)

Owner 5/19 "你来操作" 钦定 + 你 0-code rule 守 + 现 hotfix landed:
1. 你 cherry-pick 6f41779ab + restart Console
2. POST /api/prediction/publish Arsenal trophy YES 1 share @ $0.92
3. 期望: escrow lock chain TX 成功 (~2.5 KAS stake 8-decimal) + DB row + broadcast TX
4. POST /api/prediction/accept (self-take J2 maker / J2 taker) → state machine open→matched
5. settler 5min tick → state 推 verifying (Arsenal trophy 未 resolve, gamma stays pending)

= **r177 Phase 2 真闭环 first real e2e fire 准备** (= Owner UAT unblock)

## R-CHAIN-AMOUNT-PRECISION-SUFFICIENCY sediment

KI-30 不仅 prediction, **任何 sendCommandAsync transfer / send_kas** 都必 toFixed(8). lint rule 跨 service 守 (不限 prediction file).

已扫 codebase 现存 chain TX amount sites — exchange/auto-deliver/settler-router 等 都用 `String(deliveringOffer.give_amount)` 等 (= raw DB string, 不是 JS float, 安全). prediction publish 我引入的 `String(stakeKas)` (= JS float) 是 first regression. KI-30 lint rule 现守住.
