Platform matrix
Nav Platform Matrix. Each row is (os, arch) plus Package type (Single file / Multi file). OS/Arch comboboxes use catalog slugs (darwin stores as macos). Do not treat display names as identity.
- Open Platform Matrix.
- Click Register platform.
- Set OS, Arch, Package type, optional Default delta algo, Delta source count, HW variant policy, Min OS, Min API level, Fallback arch.
- After a published line exists for that pair, package type cannot change (
PACKAGE_TYPE_IMMUTABLEpackage_type locked after a published line exists). Copy: “Package type is locked once a version has been published for this platform.”
Type decides incremental path: single file may use binary delta; multi-file uses pack. Concepts: Platform matrix.
