Nail down which backend each LLM path uses, and make the dream cycle resilient to
a backend being down (the MI50 outage left profile/era/narrative — pinned to mi50
with no fallback — aborting every dream cycle).
- Consolidation (summaries + profile/era/narrative) -> cloud via SUMMARY_BACKEND=
cloud (.env, not committed). Matches the documented lesson that the MI50 is too
slow/hot for bulk consolidation; nothing background touches the card now.
- llm.complete_with_fallback(): try the primary backend, fall back to cloud on
error (re-raise if already cloud / no key). Wired into reflect + think so the
introspection voice (3090/dolphin) survives the gaming PC being powered off.
- dream coherence stage is now fault-isolated: a rebuild failure logs + continues
instead of sinking the whole pass (reflection still runs).
- .env: removed stale INTROSPECTION_BACKEND=mi50 (live routing is the web-switchable
introspection_mode DB setting = dolphin/3090; the var only fed a dead fallback).
Verified: forced cycle runs consolidation on cloud, introspection on the 3090,
completes with zero MI50 calls. 206 pass, ruff clean.
