Praveen K Palaniswamy 65e81158ab fix(ollama): route models by advertised capability (#11088)
Landed with the design call resolved per the owner's pick — **option 1**: the synced store is now endpoint-agnostic (persistDiscoveredModels and managedModelImport no longer drop non-chat models at write time), and chat selectability moved to read time (auto-pool expansion in autoStrategy applies filterChatSelectableModels; the models-route projection already had its chatOnly filter). Your discovery test now passes end-to-end (3/3): /api/show capabilities persist per connection and image/embedding requests route through the advertising host.

Reconciliation notes: conflicted areas merged onto the current tip (adobe discovery import, requestedModel preflight signature, resolvedProvider fast-path coexists with the synced-route override — explicit resolution wins); carried base-red drains (#10055 memoization, #11071 test variants) dropped as already-landed; the managed-model-import exclusion test was propagated to the new contract (image/video models persist; the read filter still hides them from chat pickers — pinned by a new assertion). Full battery: 205/206 focused (the one red is a confirmed periodic-timer timing flake on the loaded devbox — 20/20 isolated), autoCombo vitest 30/30, combo suites 46/46, gates + typecheck clean.

Thank you @yourspraveen — the capability probe + routing design was right; it just needed the store contract opened up. Fixes #11087.

/**
* Issue #3061 — No-auth providers (opencode / opencode-zen) infinite
* account-fallback loop on a persistent upstream error → unbounded DB growth /
* disk exhaustion.
*
* For a no-auth provider, getProviderCredentials early-returns synthetic
* credentials with connectionId "noauth" BEFORE honoring the exclusion set
* (src/sse/services/auth.ts: the NOAUTH_PROVIDERS block and the opencode-zen
* keyless fallback). So when the chat fallback loop marks the failed "noauth"
* connection and excludes it, the selector hands "noauth" right back → it loops
* forever, writing key-health + request logs every iteration until the disk
* fills (see @paraflu's "failure #320" trace in discussion #3038).
*
* Loop-breaking invariant under test: once "noauth" is in excludeConnectionIds,
* the selector MUST return null (no remaining candidate) so the chat handler
* stops after a single attempt instead of re-selecting the same synthetic
* connection. The happy-path (nothing excluded → synthetic noauth) must stay
* intact so keyless access still works.
