- adapters/fs: FsProxy + fsworker run each file op in a killable subprocess;
progress-stall watchdog (FS_HANG_TIMEOUT_MS) for copy/hash, total timeout for
quick ops; SIGTERM -> SIGKILL -> FsError('TIMEOUT'); stat/checkRoot timeouts
never read as missing
- copyWithVerify: onExisting conflict/skip/replace (hardlink backup + atomic
rename, old file to .umt-trash or deleted), sweep stale partials before write,
document why permissions/owner are not copied
- filesMatch/filesMatchSha256 throw FsError on read failure instead of
match=false; crossDeviceMove skips redundant re-hash after sha256 copy
- FsErrorCode TIMEOUT + fsErrorClass; organize executeRecord routes fs ops
through fsproxy, retries TIMEOUT/IO up to FS_TRANSFER_MAX_ATTEMPTS then opens
a decision without deleting the record; reconcile errors no longer reported
as EEXIST
- domain: subtitle .default marker (ORGANIZE_DEFAULT_SUBTITLE_LANG) and
findOtherVersions (same season/episode/part, video only) as upgrade
disposal candidates
- scripts/bench/fs-bench.ts and benchmark record in porting doc
