Switching the chat model from a reasoning-capable model (e.g. DeepSeek, which honours "high") to the local llama.cpp Gemma model (which supports "off" only) left the stale effort in place and surfaced the gateway's rejection as a red banner: Failed to change effort: thinkingLevel "high" is not supported for llamacpp/gemma4-e2b-it-q4_0 (use off) Root cause is two-sided: - Server: applyModelOverrideToAllAgentSessions repointed each session's model/provider but never touched the sticky per-session thinkingLevel, so "high" persisted against a model that cannot honour it. - Client: the wire push could send a level the active model rejects during the catalog/snapshot race, and the rejection was shown as a failure banner. Changes: - Sweep now normalises a session's sticky thinkingLevel to the new provider's capability (folds an unsupported level to that provider's default), using the shared getProviderReasoningConfig so client and server read one capability source. - ChatPopup routes every wire push through resolveWireThinkingLevel, which clamps to the active provider and holds the push while the provider is still unknown; the picker state defaults to off. - If the gateway still rejects a level, the client honours the fallback named in its message and snaps to it silently instead of erroring. Unit tests cover the remote->local model switch on both sides.
📝 WalkthroughWalkthroughThe change adds provider-aware thinking-level validation and fallback handling. Chat sessions now defer unresolved provider values, normalize unsupported levels during model overrides, and recover from gateway errors by applying suggested fallback levels. ChangesThinking-level safety and provider handling
Estimated code review effort: 3 (Moderate) | ~20 minutes Mergeability Score: 🔵 Low · up to The change prevents unsupported reasoning settings from reaching the gateway and normalizes stale preferences during model switches. A low merge-readiness risk remains because a rare in-flight rejection may overwrite a newer provider preference, and validation should reject inherited property names explicitly; both are bounded follow-ups.

Ignore fallbacks from superseded sessions.patch requests.
A pending patch can reject after the user switches providers. The catch handler then writes the fallback under the captured old provider at Line 696 and updates the current shared thinkingLevel at Line 698.
For example, a pending remote-provider high patch can reject with (use off) after a switch to llama.cpp. This replaces the remote provider's persisted high preference with off.
Track a patch revision or the current provider and session key. Apply the fallback only when the rejected request is still current. Do not reset lastSentThinkingRef for an obsolete request.

Problem
Changing the chat header's reasoning-effort picker to a level the currently
selected model does not support surfaced the gateway's rejection as a red
error banner, e.g.:
The most reliable way to reach this: pick a reasoning-capable model (ClawBox
AI / DeepSeek honours
high), set effort to High, then switch the picker tothe local Gemma (llama.cpp) model — which supports
offonly. The stalehighcarried over.Root cause (two-sided)
applyModelOverrideToAllAgentSessionsrepointed each session'smodel/provider fields but never touched the sticky per-session
thinkingLevel. A session that hadhighunder DeepSeek kepthighafterbeing swept to the local model, which cannot honour it.
sessions.patch) could send a level the activemodel rejects during the catalog/snapshot race, and the rejection was shown
as a failure banner. The picker state also defaulted to a speculative
highbefore the active provider was known.Fix
thinkingLevelto thenew provider's capability — an unsupported level is folded to that
provider's default (
offfor local llama.cpp) — using the sharedgetProviderReasoningConfig, so the client picker and the server sweep reada single capability source.
ChatPopuproutes every wire push throughresolveWireThinkingLevel, whichclamps a desired level to the active provider and holds the push while the
provider is still unknown; the picker state now defaults to
off.change, or an API client), the client honours the fallback named in the
gateway's own message and snaps to it silently instead of erroring.
Tests
chat-reasoning.test.ts— the new capability helpers, incl. theremote→local switch folding
hightooff, and parsing the gateway'sfallback hint.
apply-model-override.test.ts— the sweep normalises a stale unsupportedeffort, leaves a still-supported effort intact (cloud→cloud), and never
injects an effort into sessions that had none.
Verification
Built, unit-tested (25/25 green) and typechecked on the target device, then
deployed and confirmed live: the two-model configuration reproduces the bug,
and the deployed server sweep folds a stale
hightooffon the localmodel. Existing lint/typecheck baseline unchanged.
