--offline (or RETROBIOS_INSTALL_OFFLINE=1, which the runs the
full-screen interface starts inherit) makes no network request. The
file list stops the run at once with an error event of reason
offline unless --manifest or --from-pack gives it, a file the run
would download fails at once with its own advice, and board detection
is skipped. --target and --list-targets refuse it. RETROBIOS_OFFLINE
is not reused: CI and the test suite set it for every process, and the
installer tests serve their files over loopback.
A connection now has 4 s to open, then the read keeps its 30 or 60 s
timeout: three tries that never connect end in about 15 s instead of
93, and a slow but open transfer is not cut.
A --dry-run prints its totals first. A plan taller than the screen
names the ten largest systems, and --verbose lists every system and
file. Events are unchanged.
A missing file walked every archive of the BIOS folder and every file of
its size: 3,000 ZIPs and 3,000 missing files took 186 s, now under 1 s.
--from copies and the owner of a refused file use the same lookups.
The size hint drew from every core of the system and named ares, which
loads no file of its own, so --core ares was refused. It now picks among
the names --core resolves against.
--check names why each flagged file is refused and where each core
opens it, and names a pack part missing from the folder from the
markers split_pack writes. --from-pack installs from a downloaded
pack or its parts with no network request, --manifest reads a saved
file list, both checking every hash. The end of a run names the
system or core that pulls most of the download when narrowing saves
over half.
