The OpenCode Zen relay no longer serves hy3-free (since ~2026-08-31) or
laguna-s-2.1-free (new, verified 2026-09-09): both are gone from the live
GET /zen/v1/models catalog and anonymous chat completions return
401 {"type":"ModelError","message":"Model <id> is not supported"}
(2 probes >=60s apart, x-opencode-session header present).
- hermes_cli/models_catalog_static.py: remove both slugs from the
opencode-free offline floor and the opencode-zen discovery floor;
document the delist dates in the catalog comment.
- plugins/model-providers/opencode-free: default_aux_model moves from the
dead laguna-s-2.1-free to nemotron-3.5-lightning-free (fastest surviving
anonymous model).
- tests: swap fixtures off the dead slugs; extend the floor-exclusion
invariant to cover both.
The live revalidation path already hides them when the relay is reachable;
this fixes the OFFLINE floor and the aux default, which would otherwise
offer/route to models that 401.
