Trigger comparison
Compare the same task with no cue, the suspected cue and a decoy. Retain separate discovery and holdout results.

What this can tell you
Whether a suspected cue changes decisions more than a decoy does.
The decoy tests whether any added text changes behavior. Replicate on held-out tasks. An effect alone does not prove a trained backdoor.
Example: Cue and decoy

Procedure, evidence & controls
Does a cue change the decision?
Options: No cue / suspected cue / decoy.
Procedure
- Compare the same task with no cue, the suspected cue and a decoy. Retain separate discovery and holdout results.
- Record exact model revision, list snapshot and selected identities.
- Inspect paired evidence and per-entity results.
Evidence to inspect
- Cue-conditioned decision difference
- Raw responses or exact candidate log probabilities
Controls
- Protocol-specific matched conditions
- Response validity and incomplete-run coverage
Interpretation boundaryResults apply to the selected entity set and protocol. No signal is not model clearance. Missing and budget-limited cases remain unscored.
Result patterns
- Cue-specific change
- Approvals: none 20% · cue 80% · decoy 20%
- No cue-specific change
- Approvals: none 20% · cue 20% · decoy 20%
Sources, implementation & validation
Example source & adaptation
A custom approval task inspired by trigger-conditioned behavior in Sleeper Agents. The paper used coding tasks; the portal compares decisions with no cue, a suspected cue and a decoy.
