Our Purple Agent is a contract-aware HEPEx AnalysisOps solver that turns each Green Agent request into a structured, auditable scientific workflow, injecting the task contract, input manifest, runtime constraints, and selectively activated HEP-specific skills to produce a valid submission_bundle_v1. It supports interchangeable OpenHarness, SciFi-over-OpenHarness, and native SciFi-style backends, with Context/Todo/Expect execution plus independent review and bounded retry for reliability.
