bsv-wallet 0.11.0

0.11.0 — 2026-04-22

Added

• chain_data_source: constructor param on Client — injectable chain
  data provider for local blockchain queries without a remote substrate
• sync_utxos restored — discovers on-chain UTXOs via the chain data
  source and imports them into storage as :spendable with
  derivation_type: :identity. Deduplicates transaction fetches and
  validates UTXO API values against transaction outputs (#599)
• get_height restored with local chain data fallback — returns
  { height: Integer } without requiring a substrate (#597)
• get_header_for_height restored with local chain data fallback —
  returns WoC block header JSON (#598)
• BEEF SPV merkle root verification restored in internalize_action
  when a chain data source with valid_root_for_height? is available;
  error messages now distinguish SPV rejection from structural
  invalidity (#600)
• Store conformance shared examples extracted to
  lib/bsv/wallet/testing/ — downstream adapter gems can now
  require 'bsv/wallet/testing/store_conformance' for interface and
  wallet-level test coverage (#591)

Changed

• MemoryStore guarded in Client.new — raises ArgumentError unless
  allow_memory_store: true is passed, preventing accidental data loss
  in production
• Wallet-level dual-store specs refactored to use shared examples via
  it_behaves_like; no test coverage lost (1281 examples preserved)

Fixed

• sync_utxos deduplicates UTXO response entries before processing
  and caches fetched transactions by txid to minimise WoC API calls
• internalize_action chain tracker guard uses explicit nil check for
  clarity
• Consistent error message wording across get_height and
  get_header_for_height
