The A–E grade is our heuristic synthesis — a "review this" prompt, not a verdict. Each factor is tagged by what backs it: attested (a verifiable record), reported (a third party's claim), or inferred (our own heuristic, e.g. permissions). See methodology.

No tool-safety findings — heuristic detectors run on the compute-risk cadence; a finding appears when a tool trips a rule.
