• device_repos - A matrix of the file-paths of relevant AOSP repositories this device depends on.
• build_id - Previous/current device stock build ID tags
• build_number - Previous/current device stock build number strings
• image_url - Direct link to device's latest factory image
• image_sha256 - SHA256 sum of device's latest factory image
• flash_url - Stores a formatted link to Google's web-based Flash tool which brings up the device's latest available image, additionally is used to fetch the data used to create build fingerprint changes

device.sh - Downloads single device factory images/OTA images and extracts files/firmware for it. e.g. device.sh raven

download.sh - Downloads single device factory images - e.g. download.sh raven

update-any-var.sh - Update any var in vendor/lineage/vars - e.g. update-any-var.sh build_id TQ1A.230105.001.A2 bluejay panther

update-device-vars.sh - Automatically update all $deviceName variables of supported devices after running download.sh.

extract-factory-image.sh - Extracts factory image contents for a single device from already downloaded images. e.g. extract-factory-image.sh raven

firmware.sh - Extracts firmware for a single device from already downloaded images. e.g. firmware.sh raven

get-new-device-vars.py - For internal use by many of the scripts referenced above

Relevant cross-script variables:
