Red Bear OS needs a local fork of redox-scheme to enforce the -rb1 version policy end-to-end. crates.io redox-scheme 0.11.2 pins redox_syscall = "0.9.0" exactly and libredox = "0.1.18" exactly, which Cargo refuses to satisfy with the local -rb1 forks. The fork is implemented as a TRACKED TREE under local/sources/redox-scheme/ on the active 0.2.5 branch (per local/AGENTS.md), not as a separate git repository or as a separate submodule on its own branch. The single-repo rule from local/AGENTS.md is preserved: this directory is a regular subdirectory of the RedBear-OS repo, not a separate repository.
