BTC/LTC Electrum/Fulcrum client, reworked clean from the chain-audit playbook (not ported). Every byte from a server is treated as hostile. Security: - TLS verified against the webpki root store WITH hostname checking; the accept-any-certificate verifier is gone (closes the MITM hole). The connector is built once and reused. - Addresses decoded via the `bech32` crate (full checksum + bech32m + witness version) and base58check (checksum); the hand-rolled bech32 underflow panic is removed. Coin/network enforced (reject ltc-on-btc, testnet-on-mainnet) — no byte-indexing of untrusted input. - Amounts pass a fallible checked f64->sat converter (rejects non-finite/negative/>2^53) with checked_add summation; no silent saturation to 0 / u64::MAX. estimatefee requires finite, clamps. - Bounded response read + per-exchange timeout (no OOM, no slowloris). - JSON-RPC response id correlated with the request. - Untrusted upstream text is control-stripped + length-capped before it reaches a (privately-logged) NodeError. Single `call` primitive centralizes failover + id + envelope mapping; public methods (balance/utxos/history/tip/verbose-tx/broadcast/fee) are thin wrappers. Tip-attribution helpers dropped; total_sent_from now declines (None) without resolved prevouts instead of mislabeling a receive-with-change as a send. 20 L2 tests: address->script KATs (P2WPKH/P2WSH/taproot/legacy), network rejection, panic-safety on short/garbage input, checked-sat bounds, envelope id correlation, bounded/oversized read, duplex round-trip.
