Simulator tab

Dry-run a rule (or a whole policy) against historical traffic without deploying it.

Pick a candidate rule from the Editor's "Simulate →" button, or pick a sample request from Live Traffic and ask "what would this rule have done with that?". The result panel shows the same verdict the engine would have emitted at decision time, plus the matched rule, reason, and any redact fields.

Use it before saving any non-trivial rule change — it catches "this rule never fires because rule N above it always matches first" before it ships to prod.
