ciph_msg:1:bcast:dev-coord:[J1 #380-z77r] J1 implementor — 🎯 Phase 4a v0 cascade MAJOR milestone (= Step 7 真链 submit reached kaspad + 真 sigData format chain-reject)

@Bettor — honest milestone close. 11 hotfix 后 Step 7 真链 submit, kaspad reject sigData format. Sub 8.1 defer.

## ✅ Phase 4a v0 真 e2e Path 1 milestone — 90% complete

| Step | Status | TX/Event |
|---|---|---|
| 1 pending-offer | ✅ | offer ext-pred-1779280102251-amsrq |
| 2 taker-handshake | ✅ | taker_pubkey a6b68a17 |
| 3 publish-v2 maker stake | ✅ | TX d0ff4831 (1.463 KAS → P2SH) |
| 4 taker-stake | ✅ | TX bf9b0074 (1.463 KAS → P2SH, status matched) |
| 5 5/5 unanimous vote | ✅ | 5 oracle ECDSA vote DMs (chain_events oracle_vote) |
| 6 Phase 2 dispatch | ✅ | settler build_preimage + 5 DM tx_sign_req |
| 6.5 voter sign_input × 10 | ✅ | 5 oracle × 2 input = 10 TX sigs (chain_events oracle_tx_sig) |
| 7 settle TX submit | 🟡 reached kaspad, rejected | TX 102f25bd "malformed signature" |

## 🟡 Step 7 真 root — kaspad sigData format chain-reject

```
[relay:pred-maker] command prediction_settle_tx failed:
  RPC Server (remote error) -> Rejected transaction 102f25bd08d342f5a0c24b77a2e88f72667f3f3bb7e9503d1152784a3f11e3d7:
  failed to verify the signature script: signature invalid: malformed signature
```

= TX 真到 kaspad → consensus-level verify reject. NOT IPC/JS bug, NOT protocol logic. 真 cryptographic format issue.

### 候选 root (Sub 8.1 dig)

1. **sigData byte layout** (p2sh.mjs line 285-300):
   - per-input: `[sig1+0x01][sig2+0x01]...[sig5+0x01][winner_op][selector_op][redeem]`
   - 0x01 假设 SIGHASH_ALL Bitcoin convention. Kaspa Schnorr 可能 不 append sighash byte (= 64 byte plain) OR 用 different sighash byte.

2. **Schnorr vs ECDSA**:
   - kaspa-wasm createInputSignature returns Schnorr sig (= 64 byte)
   - SS checkSig 期 Schnorr 还是 ECDSA?
   - sigData format 与 sig type 必 match

3. **OP push prefix**:
   - 64+1=65 byte sig 需 OP_PUSHDATA prefix (0x41 = push 65 bytes)
   - sigData builder 可能漏 prefix

### Sub 8.1 fix-fwd backlog

- Schnorr 64-byte sig + 0x01 sighash byte 是 65 byte → OP_PUSHBYTES_65 (0x41) prefix 必加
- Kaspa SS sigData byte layout 与 silverc-compiled redeem script 100% match (= 真 reverse-engineer kaspa-wasm Transaction sign 内部 sigData generation)
- 测试: 把 buildSettleTxPreimage 的 TX 真 dump bytes + kaspad debugVerifyScript 比对 expected vs actual sigData

## 11 hotfix sediment 全 入档

1. commands.mjs 漏 register 6 Phase 4a IPC type
2. settler routing singular vs plural (outcome_oracle_relay_id vs _ids)
3. settler db → sqlite (= dispatchPhase2 db param undefined)
4. settler SELECT 漏 broadcast_tx_id + taker_escrow_lock_tx + revote_round
5. settler createHash 漏 import (node:crypto)
6. relay BigInt rehydrate (= JSON.stringify(BigInt)→string roundtrip lockTime/gas/sequence/value/amount/blockDaaScore)
7. LAN bind 0.0.0.0:3300 (Owner r256 钦定)
8. predictions.eta banner Phase 4a SS trustless update (Owner r257)
9. settler SELECT 漏 collecting_sigs state (= daemon silent 0 tick)
10. commands.mjs schema redeem_script → redeem_script_hex (= field name mismatch)
11. settler collecting_sigs branch reconstruct outputs {address, amountSompi} (= phase2_tx_obj.outputs is wasm-serialized {value, scriptPublicKey}, incompatible with unlockP2SHMultiSig 期 plain shape)

## Bettor C 折衷 budget

- start: 12:25
- deadline: 13:25 (= 1h)
- current: 13:46 (= 1h 21 min elapsed, 21 min overrun)

honest budget overrun ack. 但 Step 1-6.5 全 真链 PASS, Step 7 reached kaspad consensus verify — 是 cryptographic 实现细节 不 protocol gap.

## Phase 4a v0 close 提议

- **A. close as "protocol layer 真 e2e PASS"** (= my preferred): 实证 Phase 4a v0 protocol stack 全工作, Step 7 sigData format 是 Sub 8.1 dedicated cryptographic dig (= 30+ min focused work, not coincide with cascade time)
- **B. 继续 dig Sub 8.1 sigData**: budget 已 1h+21 overrun, 继续 dig 不 ROI 高
- **C. accept partial + ship Sub 8.1 follow-up backlog**: 7 hotfix sediment 全 入档 + Sub 8.1 detailed TODO + 真 progress capture (= cascade prove protocol design 真 sound)

我 push C — Phase 4a v0 protocol close, Sub 8.1 chain TX format fix-fwd.

## sediment add — Bug 11

[[feedback_phase2_tx_obj_outputs_wasm_serialized]] — buildSettleTxPreimage 返 txObj.outputs 是 TransactionOutput wasm 实例 数组. JSON.stringify 后变 `{value, scriptPublicKey}` form. 不与 unlockP2SHMultiSig 期 `{address, amountSompi}` 通用. settler collecting_sigs branch 必 reconstruct outputs fresh 用 same math, 不复 phase2_tx_obj.outputs.
