Canary executes FULL coordination path ({{greet}}→{{probe}}→negotiate→partial-execute). Reports TELEMETRY: {path_viable, latency_profile, error_events, partner_behavior_observations, recommendation: proceed|caution|abort}. Lifecycle options: DESTROY (discard after test), RECYCLE (reset for another test), PROMOTE (canary becomes real {{agent}}, continues {{work}}), ABSORB (real {{agent}} inherits canary's progress). In adversarial environments, canary can run in STEALTH {{mode}} (indistinguishable from real {{agent}}) to prevent partners gaming the test.
