Conversation
The picker records its selection in config.default_model (the web-chat turn path stores the per-turn model_override there), but provider_for_role never consulted it: with an unset chat_provider the turn silently fell through to the managed backend and failed with 401 'session expired' on local-only profiles. When default_model names an explicit provider route (a configured cloud slug, a local runtime, or a claude-code/SDK provider), the chat-tier roles now use it instead of the managed fallback. Hints, managed catalog pins, bare model ids, unknown slugs, and the background specialist roles keep the previous behaviour, and an explicitly configured role route still wins. Closes tinyhumansai#6938
Tiny Sweeper reviewTiny Sweeper completed its review; deterministic results follow. State: Reviewing pending checks Review snapshot
Completeness: Complete What changed`provider_for_role` in `crates/openhuman-core/src/inference/provider/factory/routing.rs` now consults a new helper, `default_model_route_for_role`, before the managed fallback: for the chat-tier roles (chat, reasoning, agentic, coding, burst) an explicit provider route named in `config.default_model` (e.g. `my-openai:gpt-4o`, `ollama:llama3`, or `claude_agent_sdk`) is returned directly instead of falling through to the managed backend. Bare `claude_agent_sdk` is the only bare provider name honoured (the SDK resolves its model from `config.claude_agent_sdk.default_model`); bare local runtimes and bare cloud slugs carry no `:model` part and fail at construction, so they keep the managed fallback rather than erroring. Non-explicit values — tier hints (`hint:chat`), managed catalog pins (`openrouter/...`), bare model ids, unknown slugs, `openhuman:`, and empty slug/model halves — keep the managed fallback, background specialist roles are unaffected, and explicitly configured role routes still win. A new sibling test module `crates/openhuman-core/src/inference/provider/factory/routing_tests.rs` covers the routing behaviour. Features

Handle the bare Claude Agent SDK provider
The bare claude_agent_sdk value is a valid provider sentinel (CLAUDE_AGENT_SDK_PROVIDER), and the existing routing and credential checks explicitly support it. However, split_once(':')? returns None before the later dm == CLAUDE_AGENT_SDK_PROVIDER check can run, so selecting the SDK without a model in default_model still falls through to the managed backend. Handle this sentinel before requiring a colon.
[RULE] incomplete-provider-route ·
tinysweeper review on tinyhumansai#6996: a bare `claude_agent_sdk` default_model names the provider with no `:model` part, but `split_once(':')?` rejected it before the explicit CLAUDE_AGENT_SDK_PROVIDER check could run, silently falling back to the managed backend. Check bare provider names (claude_agent_sdk, configured cloud slugs, local runtimes) before the slug:model split. Bare `openai` deliberately keeps the managed fallback: the slug names the cloud provider elsewhere in the factory. Adds 4 regression tests (bare claude_agent_sdk, bare ollama, bare cloud slug, bare openai negative).

Handle bare cloud slugs consistently with credential gating
This newly accepts a bare configured cloud slug such as my-openai, but the downstream credential check only treats concrete <slug>:<model> routes as usable. role_bypasses_managed_credits will therefore resolve this as non-managed while route_has_usable_credentials returns false, leaving the managed-credits gate enabled for a valid BYOK selection. The cloud factory contract also documents configured cloud routes as <slug>:<model>, so a bare slug may not produce a usable chat model at all. Either reject bare configured cloud slugs here, or update the downstream route resolution and credential handling to give them a defined model and credential path.

Recognize bare cloud routes in the credits gate
This newly accepts a bare configured cloud slug as a route, but route_has_usable_credentials only checks cloud credentials after split_once(':'). Consequently, selecting a configured BYOK provider without a model routes the request to that provider while role_bypasses_managed_credits reports it as not usable, so users can be incorrectly held behind the managed-credits gate. Make credential detection handle bare configured cloud slugs consistently, or do not accept them here.

Drive the new default_model provider route end to end
The new routing branch is the behavioural fix (#6938): a picked BYOK/local model in default_model should route the chat turn away from the managed backend. No end-to-end test reaches it. All existing Rust E2E harnesses write default_model = "e2e-mock-model" (a bare model id that default_model_route_for_role intentionally rejects) and pass "model_override": "e2e-mock-model", so the Rust E2E (mock backend) job only ever exercises the managed fallback this change must not disturb. What a test would have to do: seed config.toml with a configured cloud provider entry (slug, endpoint pointing at the mock backend) plus default_model = "<slug>:<model>", send a web-chat turn via openhuman.channel_web_chat, and assert the upstream request lands on the provider endpoint rather than the managed backend. Without it, a regression that reverts to ignoring default_model passes the whole E2E suite silently.

CodeRabbit review on tinyhumansai#6996: bare local runtimes (ollama, lmstudio, mlx, omlx, local-openai) and bare cloud slugs carry no :model part and fail at chat-model construction (empty_model_err / unresolved provider), so routing them there would trade the managed fallback for a build-time error. Narrow the bare-provider branch to claude_agent_sdk only, which resolves its model from config.claude_agent_sdk.default_model. Bare ollama / bare cloud slugs keep the managed fallback; tests updated.
Summary
provider_for_rolenow honours an explicit provider route recorded inconfig.default_modelfor the chat-tier roles (chat,reasoning,agentic,coding,burst) when the role's own route is unset, instead of silently falling back to the managed backend.model_overrideindefault_model), so a picked BYOK/local model now actually routes the turn instead of 401ing as "session expired".openrouter/...), bare model ids, unknown slugs, and the background specialist roles (vision,memory/summarization,embeddings).Problem
Closes #6938. On a local-only profile, picking a model in the Chat UI's model picker had no effect on routing: every turn failed with
managed invoke/stream failed: status=401 ... "Invalid token" "UNAUTHORIZED", surfaced misleadingly as "Your OpenHuman session has expired". Root cause:create_turn_chat_model_with_native_tools_and_route_innerchecksresolves_to_managed_backend(role, config)before consulting the turn's chosen model, and role resolution (provider_for_role) never consultedconfig.default_model— the only place the picker records its selection.Solution
default_model_route_for_rolehelper incrates/openhuman-core/src/inference/provider/factory/routing.rs: returns thedefault_modelstring as the role's route only when it parses as an explicit provider route (a configured cloud slug, a local runtime string, or a claude-code/SDK provider) for a chat-tier role.provider_for_roleconsults it in the unset-route fall-through branch, beforeresolve_primary_cloud_provider_string. An explicitly configured role route still wins; the Pinning one chat-tier BYOK route silently re-routes the other two #6109 "each route stands alone" invariant is preserved (covered by tests).Submission Checklist
