The providers that actually resolve — REQ-061 (#255), task #256.

"bedrock" was here and threw capability_unavailable when selected. It is gone, and removing it rather than wiring it is the decision:

A declared provider that throws is worse than an absent one. It typechecks, satisfies the exhaustive switch, and fails at runtime for whoever selects it first — and it survived precisely because a closed union reads as complete coverage. The type system guarantees every member is mentioned; only a call finds out whether it is served.
Wiring it could not be verified. #256's AC-5 requires one real turn as evidence, and constructing a Bedrock model needs no network — so an unverified wiring would satisfy "resolves" while leaving its first user as its first tester. #268 settled that precedent.

Nothing is lost today: nothing could select it and get a model. Adding it back is a one-line change plus a provider-coverage.test.ts case, and that test is what will force the verification then rather than allow the same gap again.

Vertex is absent for a different reason, argued in docs/03: it serves the same Gemini models the google provider does, differing in credentials rather than model family, so a second member would make every allowedProviders policy name both to mean "Gemini".
