The act path minted IDs per hop and trusted whatever Praxis returned
for a scoped attention query. A service that ignored the entity filter
would have had its unrelated items read back to the owner as his. The
handler now assigns one correlation ID at the top of the action and
passes it down, and drops any item the response did not tag with the
requested entity. Traces are written to the trace table with the
causation ID and HTTP status hoisted into columns, the duplicate
legacy Hexis trace is gone, truncated lists say so, and a rejected
credential gets its own reply instead of looking like an outage.
Found in review of #83 and #84.
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.
