The previous default read timeout of 15 milliseconds was too low for typical network operations and could cause premature timeouts. Increased to 100ms to allow sufficient time for network reads to complete. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
…test_sync Added a documentation comment block for the dash_spv_ffi_client_test_sync function to describe its purpose, parameter, and return value. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

Extract the complex logic for loading pre-calculated masternode data from terminal blocks into a dedicated private method `load_precalculated_masternode_data`. This improves code readability and maintainability by reducing the complexity of the `start_masternode_sync` method. The refactoring moves approximately 140 lines of code from the inline implementation (lines 279-420) into a new async method that handles: - Terminal block hash validation - Masternode entry parsing and conversion - BLS public key and address validation - Masternode list construction and engine updates No functional changes were made during this refactoring. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

- Keep only the latest 2 terminal blocks for each network - Reduces embedded data from ~37.4MB to ~3.3MB (91% reduction) - Mainnet: Keep blocks 1,950,000 and 2,000,000 - Testnet: Keep blocks 850,000 and 900,000 - Update code and documentation to reflect changes The older terminal blocks provided minimal practical value since: - SPV clients always sync to the latest blockchain tip - Masternode diffs work from any starting height - The main optimization is having a recent starting point 🤖 Generated with Claude Code (https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
- Further reduce embedded data from ~3.3MB to ~1.6MB (additional 52% reduction) - Mainnet: Keep only block 2,000,000 - Testnet: Keep only block 900,000 - Total reduction from original: ~37.4MB to ~1.6MB (96% reduction) Since SPV clients always sync to the current tip and the code always selects the highest available terminal block, keeping multiple blocks provides no practical benefit. The single latest block per network is sufficient for optimization while minimizing binary size. 🤖 Generated with Claude Code (https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
Remove unnecessary String allocation by returning &'static str directly from request_phase() method. The string constants are already static, so converting them to owned Strings was wasteful. Only convert to String when actually needed (e.g., when inserting into HashMap<String, _>).
