 "_comment": "ARCH-02 SYNTHETIC FIXTURE - a PRE-DEV-02 flat state file. NOT a copy of the live box's /data/state.json; this session cannot read that one and did not try. It is built to carry, deliberately, the two shapes that state built by the happy path does not have: a LATCHED SAFETY-02 failsafe under the flat spelling, and a real maintenance history under the flat spelling. Both are LEGACY-SHAPED: there is no schema_version and no maint_schema_version, so this file was last written by a controller that had never heard of unit namespaces. Losing either one is silent.",
