+"""Offline context-efficiency gate with retrieval and agent-safety guardrails.
+
+Token reduction is useful only when the compact context still lets an agent act on
+the supported fact and keeps unsafe sources out of an answer.  The existing
+``context_economy`` benchmark measures workload-level reader context and evidence
+quality, while ``grounded`` and ``adversarial_memory_security`` exercise their
+respective contracts.  This deliberately small fixture composes those contracts
+at the prompt boundary:
+
+* an answerable operational question remains grounded and cited;
+* an off-topic question abstains instead of turning the smaller context into a
+  guess; and
+* an untrusted instruction-shaped source is never cited or echoed.
+
+All counts use ``engraphis.regex.v1`` and the deterministic offline engine.  The
+reported savings compare packed reader context to replaying every fixture source;
+they are not provider billing, completion-token, or model-quality estimates.
+
+Run with ``python -m eval.context_efficiency_guardrails``.  Stdout is a single
+redacted JSON object suitable for a focused CI regression.
