Summary

  • add dedicated mcp_execution_output blockstore column family keyed by slot
  • add Blockstore helpers to put/get ordered MCP execution output bytes, including explicit empty-output writes
  • wire the new CF into metrics and purge paths
  • extend purge and CF sanity tests to cover MCP execution output storage

Testing

  • cargo test -p solana-ledger --lib test_mcp_execution_output_put_get_empty -- --nocapture
  • cargo test -p solana-ledger --lib test_purge_slots -- --nocapture
  • cargo test -p solana-ledger --lib test_cf_names_and_descriptors_equal_length -- --nocapture

Closes #17
