An installed model knew one coding agent: the one it was installed with.
The launch check never asked about the agent, only about the endpoint
and the model, so nothing stopped a second one. What was missing is the
list, and a way to get an agent that is not on the Mac yet.
The install view gains `harnesses`: every catalogue harness the model in
use can be run with, each with how it stands (`ready`, `installable`,
`installing`, `setup-needed`), the literal install command, a readiness
mark for scripts, and the actions the server accepts for it. `cli` stays
the default agent, and names one that can be started whenever one can,
so a client that reads only `cli` never starts an agent that is gone.
`POST /api/local-model/agent { cli }` installs one more agent beside an
installed model. It is not a job and not an event of the reducer: the
state stays `installed` whatever the installer does, so a failed npm
install never blocks a session on a model that works. Same install slot
and same compiled stock command as the `agent` step, one at a time, the
outcome in memory only.
The catalogue:
- `pi` is no longer gated. Its two open questions were answered by a run
against a real model (the `name:tag` id reaches the runtime unchanged;
its first request is 2,096 tokens), and Codeman now passes it the
window. Its minimum is 65536 like the others: nothing below was run,
and no model row offers less, so no Mac's pick changes.
- `deepseek` is new. It is a launcher: its install command leaves it
with nothing to launch, so it is never reported installable (read off
`discovery.launcherProfile`, not the id) and a Mac is offered it only
where it was already set up. Its tool round trip was seen on a
scripted endpoint only; the header says how to gate it again.
- a row may carry `readyMark`; `opencode` has the measured one.
A switch no longer refuses for the agent a model was checked with when
another agent that can run it is on the Mac.
