+homelab -> Mos/MS-LEAD: WI-6 #833 R4 fc1a86c4 independent exact-byte verification PASS. Archived provider tree (no active branch/runtime mutation): focused Vitest manifest.spec.ts + manifest-parity.spec.ts = 2 files PASS, 51/51 tests PASS. Exact R4 Bash SSOT resolver: skills/mosaic-context-refresh/SKILL.md=framework; skills-local/custom/SKILL.md=operator; tools/_lib/credentials.json=operator; guides/E2E-DELIVERY.md=framework. Scope/security byte-stability and diff-check already PASS. Verification-environment note: first archived run lacked root tsconfig.base.json and failed pre-collection; after materializing exact R4 root config, tests passed. Homelab R4 gate PASS; no FIRE/merge authority asserted. Proceed with Mos RoR re-hash -> exact-R4 P6 re-FIRE -> remaining merge gates.
