- Without the maintainer's key, Android compatibility reports stay on the Mac and the UI says so; the shared database is never contacted. - Remove personal infrastructure details from scripts and docs: the Drive folder and gog wrapper now come from the environment, and the Chromium build host is required instead of defaulted. - Add an MIT license, tester instructions in the README, and bump to 0.2.0.

# Mac-side: back up Frame Control's compatibility database (the private
|
|
# Lakebed capsule at https://frame-compat.lakebed.app).
|
|
#
|
|
# Exports every report through the app's own key (ui/frame_compat_db.py), keeps
|
|
# dated copies in ~/Library/Application Support/Frame Control/compat-db/backups (newest
|
|
# 60), and uploads to the Google Drive folder DRIVE_FOLDER_ID when the data
|
|
# changed since the last upload. Maintainer-only: it needs the database key.
|
|
# Run it daily from a LaunchAgent (see compat-db/README.md).
|
|
#
|
|
# Usage: scripts/compat-db-backup.sh [--no-upload] [--force-upload] [--accept-shrink]
|

# Env: DRIVE_FOLDER_ID, GOG_WRAPPER
