Run ruff check --fix: remove unused imports (F401), fix f-strings
without placeholders (F541), remove unused variables (F841), fix
duplicate dict key (F601).
Run isort --profile black: normalize import ordering across all files.
Run ruff format: apply consistent formatting (black-compatible) to
all 58 Python files.
3 intentional E402 remain (imports after require_yaml() must execute
after yaml is available).
- batocera_scraper: fix OrderedDict parsing for ast.literal_eval
- auto_fetch: fix TypeError when sha1/md5 is None
- verify: filter non-ZIP files for zipped_file entries (F2)
- verify: distinguish ZIP read errors from hash mismatches (F5)
- generate_pack: track seen_destinations with source hash (F7)
Batocera ep64/ep128.zip now correctly reported as MISSING
instead of false UNTESTED (resolved to .rom instead of .zip)
Critical: stream large file downloads (OOM fix), fix basename match
in auto_fetch, include hashes in pack grouping fingerprint, handle
not_in_zip status in verify, fix escaped quotes in batocera parser.
Important: deduplicate shared group includes, catch coreinfo network
errors, fix NODEDUP path component match, fix CI word splitting on
spaces, replace bare except Exception in 3 files.
Minor: argparse in list_platforms, specific exceptions in download.py.
