The product model has no cross-process writer exclusion (the coordinator serializes per-session operations in-process; the README documents one live writer per session), so the wx-created .lock sibling only guarded byte-level races while adding two failure modes: a crash leaves a stale lock that permanently wedges that log's appends/repairs/replacements, and a post-commit lock cleanup failure makes a committed append look failed, so the retained write-behind batch retries into duplicate seqs. Remove withLogLock and keep replaceStored's revision compare-and-swap at the commit boundary (recheck immediately before the atomic rename).
