Fail-open but no longer silent. When the dynamic context fetch yields nothing,
append a short status line to the injected context so a session can tell
'couldn't load live context' apart from 'Scribe had nothing to say':
- endpoint+token present but fetch empty/failed -> 'instance unreachable / request failed'
- endpoint present but token absent -> fingerprints the known Claude Code
userConfig export gap ('API token did not reach this hook')
A fully unconfigured install (no url AND no token) stays quiet — static-only is
the intended mode there. Static Tier 1 still always carries the mandate.
