The Poolside entry landed with an empty `models` list because the public
matrix could only reach the unauthenticated endpoint, which answers 401
`No Authorization header provided` — the same response that a generic probe
once read back as "invalid key" and that got the provider dropped (#2723,
#3054). An authenticated probe against `/v1/models` (2026-08-07, #9085)
returned 200 and the full Preview catalog, so the two models are now static:
poolside/laguna-xs-2.1 Laguna XS 2.1
poolside/laguna-s-2.1 Laguna S 2.1
Both report 262144 context, 32768 max completion tokens, `tools` and
`reasoning`, and are text-only and free during Preview. The XS id is the
catalog form; the `laguna-xs.2` variant circulating in third-party listings
does not address this host. `passthroughModels` stays on, so live discovery
still admits models the Preview adds later.
