/**
 * Policy gate — suppression fully disabled for the demo.
 *
 * Every real collision surfaces an intervention. Accept/Dismiss are still
 * recorded as outcomes but carry NO gating meaning: dismissing one collision
 * never silences future ones, and there is no per-pod cooldown throttling
 * consecutive conflicts. The only filter is severity: `info` collisions are
 * informational, not actionable, so they don't nudge. The same-collision
 * single-shot dedupe lives in `PodmanAgent.handle` (activeConflicts), so
 * removing the cooldown does not cause repeat spam of an unresolved collision.
 *
 * (Prior dismissal-based suppression over-generalized: one README discard
 * permanently muted all README clashes via loose file/vector recall.)
