Every Nexus and Praxis request now carries the contract version, an X-Requested-By identifying Maven, a correlation ID (generated per request when the call is not part of a traced action), and a bearer token when one is configured. Nexus/Praxis/Hexis config blocks grew an optional token field, env-expandable so the secret stays out of the committed config; the vendored hexis client predates bearer auth, so a configured Hexis token logs a loud warning instead of pretending to authenticate. Client failures are now a typed *ecosystemError carrying service, operation and HTTP status, classifying unauthorized, contract-mismatch and unreachable without matching on message text. Trace records are written for resolution, discovery, confirmation and execution — on failure as well as success — with status, duration, correlation and causation ids, HTTP status and failure class, and the utterance redacted to its length. Traces were never actually persisted before: both trace writers used fact kind "system", which the store's CHECK constraint rejects, and the error was discarded.
