Several assertions passed against code with the behaviour removed. The
independent-outage test shared no state to begin with, the capability
fixture used to prove read-only filtering was already mutating, and
route-level faults were simulated with a separate fake instead of the
shared one. The harness now takes per-route faults and a ticking clock,
so durations are measurable and one dead endpoint can be shown not to
mute a whole service. New cases cover a resolved reference with no
entity, a rejected credential, a malformed Praxis body, foreign items
in a scoped response, named truncation, traces staying out of facts,
and enrichment making progress while its oldest batch is backed off.
Found in review of #82.
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.
