Codex found the per-call tier never reaches the transport: the protocol
takes five unpacked arguments, not the request, so a field on ChatRequest
goes nowhere. That is now its own step, fakes included.
It also found the mapped tier would be lost — resolve_thinking returned
only the payload, so telemetry would file a mapped call under a tier it
never ran at, which is exactly the grouping task 10 depends on.
Ordered so the two type changes land first and everything else consumes
them: capability and wire in parallel, then the five gates, then the two
entry points, then cache key and telemetry, then the transport.
Task 10 exists because the human settled that the capability table is
measured through new-api, not read off a vendor page. Task 1 lands the
documented guess; task 10 replaces it with what the gateway does.
