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.
Add an entity-scoped attention capability: the subject is resolved to a
canonical Nexus entity_id, the id travels to Praxis as a query scope
instead of being dropped after resolution, and Maven's own facts already
tagged with the same id join the answer. Ambiguous, unknown, degraded and
no-Nexus cases each get a distinct reply and never a scoped query without
a scope.
Give the fact-enrichment worker per-fact exponential backoff capped at an
hour and a status report of pending/in-backoff/worst-attempt counts, so a
long Nexus outage shows as a visible backlog rather than facts that
silently never got tagged. Nothing is ever given up on.
voice.go is still the biggest file in cmd/mavend and most of what is left
has nothing to do with the audio path. The ecosystem integration is one
such lump: it talks to Nexus, Praxis and Hexis over HTTP and only touches
the handler for its store and clock. Lifting it into ecosystem_acts.go
puts it next to ecosystem.go, where the clients it drives already live.
Move-only: handlePraxisAct, recordPraxisTrace (called from nowhere else),
handleHexisAct and execHexis verbatim, plus the two imports that became
unused in voice.go.
