Oracle wave-4 watch-outs:
- '5xx count: 1 should not be hidden'
- 'Add one future regression check that fails if both primary and
   fallback LLM paths fail, since the fallback tunnel is now part
   of the live behavior'

E2E now reports llm-gateway 5xx and system 5xx as two distinct
counts. The canvas-primary 503 is acknowledged + counted; only
system 5xx must be zero. New no_system_5xx assertion guards that.

wave4 adds gap1_cascade_did_not_exhaust: fails if telemetry shows
'[llm] all gateways exhausted' on the live assistant path. Locks
in that at least one gateway (primary or fallback-dev) is
returning real model output.
