- still_battery.py run --cold: posix_fadvise(DONTNEED) on a set's input files just before its run, so
every timed row is a cold read without root (the page-cache column confirms it).
- Alvra sets use the depositors' pixel masks (--mask-good); the MbCO int16 glob now finds the copies,
which keep the tarball's directory tree; LCLS 242 states its wavelength (the XTC does not).
- EXTERNAL_TEST_DATA_STILLS.md names the mask files and the one MbCO dark run that holds no frames.
