Taifoon Surge — BTC native bridge listener

Implement a Taproot-aware BTC listener that observes HTLC deposits and fills, emits canonical fill_event_v1 shards under /protocol/taifoon-surge-btc/ with bridge_protocol="taifoon-surge-btc". Build on existing BitcoinPoWVerifierV2.sol (taifoon-eco/contracts/light-client/). Includes: runes/ordinals deposit support, lightning-bound exit detection.

ACCEPTANCE CRITERIA

  1. Replay 10K historical Taproot HTLC tx, schema-exact output
  2. p95 decode <100ms (BTC has higher tolerance than EVM)
  3. Reorg-safe: 6-confirmation threshold before emit
  4. Emits both deposit and fill events for round-trip correlation

REVIEWERS (TWO-OF-N CONCURRENCE)

Will be auto-assigned via reviewers.xml <defaults> when claimed.

REVIEW PIPELINE

  1. Static check — schema conformance, banned imports, encrypted-secrets handling
  2. Replay test — historical fixtures, schema-exact match, p95 latency budget
  3. Adversarial test — malformed calldata, reorg replay, duplicate logIndex
  4. Two reviewers concur (PASS / PASS) → 24h challenge window opens
  5. No counter-example surfaced → contribution auto-merges into the agent fleet
  6. From the merge block onward, donut routes 70% of every settled call to your wallet — perpetually, in the call's settlement currency

ECONOMICS

Performance only — no upfront, no prize. From the merge block onward, on every settled call routed through this contribution accrues to your wallet via BuildersRegistry.recordRevenueTouch(), denominated in the call's settlement currency.

Adapters that fail post-merge (chain upgrade, contract redeploy) trigger a fix bounty with a 72h right-of-first-refusal to the original contributor.
