Chaser – Evidence-first agent provenance and governance

Built Chaser as an evidence-first provenance and governance layer that ingests agent and workflow events, reconstructs deterministic session activity, and produces redacted, integrity-linked artefacts. Implemented a Docker-based stack including backend, frontend, OPA policy engine, Postgres, and OpenTelemetry collector orchestrated via docker compose for local pilots. Added optional shared-secret authentication for governance endpoints configured via environment variables. Created a golden-path demo workflow that exercises the core API, generating cases, sessions, evidence packs, quarantine artefacts, enclave tokens, and controls reports. Defined core outputs such as session replay steps, exposure storylines, evidence packs, enclave workflows, and deterministic controls reports, each backed by evidence identifiers and hashes.
