The build system had multiple authoritative docs claiming 'Red Bear OS 0.1.0 (baseline)' and 'branch 0.2.5' long after the working branch advanced to 0.3.1. Operator confusion was inevitable: - 'repo --version' showed 0.2.5 (root Cargo.toml drift, fixed G2) - AGENTS.md said rust-toolchain = nightly-2025-10-03 (actual nightly-2026-05-24) - local/AGENTS.md example versions all said 0.2.5 (should be 0.3.1) - README.md and docs/* claimed 'baseline 0.1.0' on the current branch (which has 0.3.1 forks as the source of truth) This commit syncs the docs to reality without rewriting historical content where the 0.1.0 reference is genuinely about the legacy release archive at sources/redbear-0.1.0/ (which DOES exist and serves the release-mode fallback per BUILD-SYSTEM-SETUP). The 0.1.0 release-archive references are preserved with explicit 'legacy' annotations because that archive IS the durable record of the old overlay-patch approach and is used by restore-sources.sh --release=0.1.0 in fallback build paths. Updated across: - AGENTS.md (root): toolchain, current baseline phrasing - local/AGENTS.md: example versions 0.2.5->0.3.1, RELEASE MODEL clarified that current source-of-truth is local/sources/ forks - README.md: branch refs 0.2.5->0.3.1 - docs/06-BUILD-SYSTEM-SETUP.md: baseline 0.1.0->0.3.1 - local/docs/UPSTREAM-SYNC-PROCEDURE.md: baseline clarified - local/docs/LOCAL-FORK-SUPREMACY-POLICY.md: snapshot phrasing - local/docs/CUB-PACKAGE-MANAGER.md: archive context clarified
