P0.6: durable write outcome for safe lost-response recovery.

Fields

committed: bool

committed_statements: u64

last_commit_hlc: Vec<u8>

16-byte big-endian HLC, or empty when no commit timestamp is available.

first_commit_statement_index: Option<u64>

last_commit_statement_index: Option<u64>

completed_statements: u64

current_statement_index: u64

terminal_state: String

serialization_state: String

last_commit_epoch: Option<u64>

Optional legacy epoch; absence means “no epoch” (never use 0 as missing).

Implementations
