The rc3 release failed on a correctly-built archive. `unzip -v` ends with a TOTALS row whose first field is also numeric, so "numeric $1" matched it and the check read the byte count as a compression method — reporting a fully stored archive as compressed. The same noise appeared in my local negative control as a phantom third entry and I read past it, which is why this reached CI. The method column must look like a method for the row to be an entry at all. Verified in both directions: a stored archive passes, a deflated one flags every member and nothing else.

# Drop the resulting autorun.zip on the root of a player's storage (microSD, USB, or internal

# flash over SFTP) and power-cycle. autozip.brs unpacks it in place, marks it done, and reboots
|
|
# into the player. One file to distribute instead of four that must all land intact.
|
|
#
|
|
# ⚠️ The zip must expand to files AT ITS ROOT — no wrapper directory. A player extracts to the
|
|
# storage root, so a nested folder puts autorun.brs somewhere the player never looks and the
|
|
# card silently does nothing. That is why this zips from *inside* the staging directory.
|
|
#
|
|
# ⚠️ autorun.brs must NOT sit next to autorun.zip on the storage root: its presence stops the zip
|
|
# being processed at all. It belongs inside, which is where this puts it.
