- aggregate: frozen days are dropped after deduplication, not before. A
request straddling midnight whose best line sat on a day frozen since
was counted again on the open day. On equal output the earliest line now
wins (it was the first one read), so the choice no longer depends on
which files a beat reads.
- aggregate: unreadable directories, failed stats (ENOENT included) and
stream errors are counted in `readErrors`; a missing root is still an
empty scan. The beat then freezes no new day (nextState freeze: false),
still pushes, and logs `read_errors=N` with no path.
- limits: the response is read chunk by chunk and counted in bytes; past
256 KiB the stream is cancelled instead of being read in full and
measured in characters.
- state: a test now covers the chmodSync of a leftover temp file.
Each fix was checked by mutation (13 mutations, 13 red).
