<preamble>
Read {{meta_rules_path}}. The guard has fetched fleet context to {{fleet_context_path}}.
If that file contains the line `petrova.context unreachable, working without fleet state`,
you are in DEGRADED state: you MUST echo that exact line, you MUST NOT name any phase,
acceptance gate, or drift-watch that is not literally present in the file, and you fall
back to `docs/` + `git log` only.
