Mock

A workflow names this provider in the model line (model: mock/mock-default), and the engine speaks mock on the wire. No key exists on this path: nothing to rotate, nothing to leak.

Aliases are what the file may write; the engine pins each one to an exact upstream id, so a run stays reproducible after a vendor rotates names.

1. 1Nothing to install and no key. The engine ships it.
2. 2Rehearse any file nika run file.nika.yaml --model mock/mock-default

Pick it for always first. Author against mock, then swap the model line. Then prove the seat: nika doctor names every provider this binary can reach.

Moving off Mock is editing one line. The rest of the file (tasks, permits, outputs, the trace) does not change. The register orders the catalog local first; beyond it the engine embeds 21 more OpenAI-compatible endpoints.
