# CASAN Plan-20 — Agentic Bridge acceptance + threat suite.
#
# Covers Spike-20 §6 cases C1–C12 plus the Wave-0.5 threat tests (tamper,
# timeout, bypass, injection, replay) and the single-model invariant. Fully
# deterministic and offline: the bridge NEVER calls a model, so no network,
# mock server or provider is needed. Each group runs against an isolated
# CASAN_STATE_ROOT so trace/metrics counts are exact.
