//! The on-disk ledger tail rule (TS `event-log.ts`, this ledger only):
//! append-only JSONL, one `O_APPEND` write per event, no fsync (TS
//! `appendSync` without `durable`).
//!
//! Tail rule: an unterminated final line is an uncommitted append —
//! skipped on replay even when it parses, truncated at its byte offset
//! before the next append, never newline-completed (completion would
//! turn a line a strict parser rejects into permanent interior poison).
//! Interior malformed lines fail closed. Repair runs only on append,
//! never on read: a viewer may replay a live writer's log.
