Anthropic's Frontier Red Team (2026-07-30) reported an incident where a model correctly identified an action as a real-world attack, then talked itself back into acting by deciding the environment must be a simulation (unrecognized cert authorities, a staged-looking system date). CSIS's capability-tier ceiling assumes the tripwire layer catches this reasoning shape before an artifact reaches the Verifier, so it's worth a dedicated pattern rather than relying on the existing escalate_to_t2/shutdown_evasion patterns, which target different phrasing.

Summary
Adds a new tripwire pattern,
sim_rationalization, that catches text where a model justifies proceeding with an action by convincing itself the environment "must be a simulation" — the specific reasoning shape from a real incident, not bare mentions of sandboxes/simulations in ordinary text.Source
Theme
Theme 3 — Constitutional / safety primitives (tripwires, capability tiers). Also touches theme 6 (substrate/capability boundaries — real-vs-simulated environment confusion).
Touches
csis/safety/tripwires.py:_TRIP_PATTERNS— a pure addition to the existing pattern list, following the same shape asshutdown_evasion/escalate_to_t2.tests/test_safety.py— one positive, one false-positive-guard regression test.Size / risk
Trivial (~30 LOC), low risk. Does not touch any cycle-9 chokepoint (
Coordinator.__init__,_BackendTracker,writer_iteration_id, promotion CAS) — this is a regex addition to an existing pattern list scanned byTripwires.scan_text, same call path as every other pattern.Test plan
Both pass locally (252 passed, including the 2 new tests).
