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.

  1. Open Platform Matrix.
  2. Click Register platform.
  3. Set OS, Arch, Package type, optional Default delta algo, Delta source count, HW variant policy, Min OS, Min API level, Fallback arch.
  4. 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.
