- Forward: after a line longer than the budget, the next line is read from
its start instead of being skipped with it when it crosses the chunk end.
- Backward: the line before a skipped long line is read whole; a floor that
turned out to be a line start no longer stalls.
- A chunk the shared forward budget cut short is not applied (it read as one
over-long line) but read in a later pass, so a first open of a long main
transcript reaches the subagents in the same sync.
- Load older reads a full budget block of up to three transcripts per click,
taking turns, instead of splitting one budget (a normal Write longer than
the share was skipped for good).
- A subagent transcript that vanished loses its cursor, so Load older does not
stay on forever.
- POST /api/cleanup-state forgets the history of every record it drops; a
startup sweep deletes edit-history files no session or record owns and
stale tmp files of other processes.
- load() rebuilds entries from known fields (string diff lines, per-edit cap
re-applied, ids counted against the byte cap), bounds pending Bash fields
and agent ids, and does not parse a file over 32 MiB.
- No re-read after Codeman's own keep-alive turn.
- Tests: regression tests for each of the above (they fail on the previous
commit); the remove-during-write test now meets the write under way; the
sync and route tests remove their stores before the temp dir, so no late
save recreates it in /tmp.
