Tiny Sweeper reviewTiny Sweeper completed its review; deterministic results follow. State: Reviewing pending checks Review snapshot
Completeness: Complete What changedThe pull request reworks composer model routing end to end. On the web client, default sends omit the `model` field so core's persisted default applies, explicit picker selections are serialized and forwarded as `model_override`, and default sends are gated behind a pending/failing model-clear write with draft restoration on failure. In core, a turn-local effective config resolves provider/model routing, the session fingerprint gains an `effective_model` field, and managed backend construction enforces the LocalOnly privacy gate before any client is built.

- Line 308: Update session fingerprint construction around
effective_session_config to include the resolved effective model, including the
persisted default_model when model_override is None. Ensure changing that
default invalidates reuse of an agent built for the previous model, while
preserving picker-selected model behavior.

Wait for the SSE subscription before submitting the turn
The task is spawned, but the test immediately posts the RPC request without waiting for the GET to complete and register its subscriber. If the core emits chat_error before the SSE connection is active, the event is lost and the test waits until its timeout even though the request behaved correctly. Use the existing ready-aware SSE helper (or add an equivalent readiness barrier) before posting the request.
Additional security observation
Synchronize the SSE subscription before submitting the turn
[RULE] sse-subscription-race
The task is spawned and the RPC request is submitted without waiting for the SSE GET to become ready. If the core emits chat_error before the stream is subscribed, the test can miss the terminal event and fail after the timeout even though routing is correct. Use the existing ready-aware helper (and signal the accepted request ID) or otherwise wait for subscription readiness before posting the request.

Exercise BYOK and local picker overrides
The new picker assertions cover only managed models and managed defaults. They do not drive a picker-selected BYOK route or a local route through channel_web_chat, so regressions in provider-prefixed BYOK/local routing can still pass this suite. Add real core-turn cases for both override types, including assertions on the resulting backend request and credentials, rather than treating the warm BYOK session here as coverage of a BYOK override.

Add the registered chip-tabs spec before running it
The settings suite invokes a chip-tabs keyboard spec that has not been added in this pull request. I could not find test/e2e/specs/chip-tabs-keyboard.spec.ts anywhere in the diff, and a runner entry pointing at a nonexistent file fails the settings flow (or is silently skipped, depending on the runner's error policy) — the behaviour this entry claims to cover is asserted nowhere. The earlier finding stands unchanged; either commit the spec alongside this registration or drop the line until it exists.
Additional e2e observation
Register the chip-tabs spec only if it exists
[RULE] e2e-uncovered
The settings suite invokes a chip-tabs keyboard spec that I could not find in the repository tree; until that spec file exists, this run line either fails or silently registers a flow for nothing. Either commit the spec or drop this registration until it is written. Not fixed by this commit; kept from earlier revisions.

Synchronize the SSE subscription before submitting the turn
This task starts the SSE GET and the RPC submission is performed immediately afterward, with no readiness handshake. The unknown-provider turn can emit chat_error before the stream is subscribed, causing the test to wait until timeout or miss the event nondeterministically. Use spawn_ready_terminal_web_chat_event_for_request (and signal the accepted request ID) or otherwise await an explicit subscription-ready signal before posting the turn.

Drive a BYOK/local picker override through the core end to end
The new assert_managed_turn cases cover managed catalog selections and persisted managed defaults, but the e2e still never sends a picker-selected BYOK or local model (huggingface:org/model, ollama:qwen3:4b-instruct) through openhuman.channel_web_chat and observes the resulting upstream request. session_routing_tests.rs covers this only by calling effective_session_config/create_chat_model_with_model_id directly, which does not exercise the web-chat turn path, the session cache, or the provider-for-role resolution as the running core performs them. A test would post channel_web_chat with model_override set to a configured BYOK slug and to a local ollama: value and assert the mock backend received the expected endpoint, model, and (for BYOK) the provider credential, plus that the persisted default_model/chat_provider are untouched.

Drive the clear-barrier send gating through a real app end to end
The composer clear-barrier (a default send now waits for a pending openhuman.inference_update_model_settings clear, retries a rejected clear, and restores the draft on failure) is a user-facing send path, but the only tests covering it are Vitest component tests with the RPC mocked. Per the repository's own rule, frontend flows belong in mocked browser/desktop E2E specs, and no Playwright spec drives the model picker clear → blocked send → retry sequence. A test would select a picker model, clear it while the settings write is pending or failing, attempt to send, and observe that no turn starts until the clear succeeds and the draft survives a failure. Until then the gating contract is asserted only against mocks.

Summary
Problem
The composer previously sent
hint:chatas a model override whenever no picker value was set. This per-turn value took precedence over the persisteddefault_model. Separately, a provider-qualified picker value could replace the model ID while the chat factory still used the existingchat_providerbinding. The resulting request could reach a different provider or model than the selection shown in the composer. Clearing a picker pin could also send before the settings RPC completed. A later saved managed-model change could reuse a cached agent because its provider binding had stayed the same. A rejected clear could keep blocking later default sends. A cloud selection with different capitalization from the configured slug could fail at the factory lookup.Solution
The web-chat session builder now creates an effective config for each turn. It uses the explicit picker selection when present, otherwise the persisted default; recognized local, configured cloud, built-in, and managed model forms select their matching chat route. Managed
openrouter/...selections, including:freeIDs, restore the managed route. Role hints, legacy aliases, and unqualified legacy model IDs retain the configured role route. Turn-local routing preserves saved settings and sibling role routes through an effective config clone.The session fingerprint records the effective provider binding and resolved model, including a saved managed default when there is no per-turn override. The frontend omits
model_overridefor normal and follow-up sends unless the user made a concrete picker selection. Picker settings writes are queued in selection order; a default send waits for a pending clear, and a rejected clear keeps the draft and shows the existing send error. A later default send retries a rejected clear and waits for persistence; the same behavior applies to queued follow-ups. Explicit-model sends remain immediate. An immediate send rejection restores the draft and attachments while preserving its error banner. Configured cloud matches use the configured slug and preserve the full model suffix, including additional colons.The common managed-model resolver now checks LocalOnly privacy mode before constructing a backend client.
Submission Checklist
7578346c85973c61afbfe6e24d88eb0a174ba014. Pinned Linux report.docs/RELEASE-MANUAL-SMOKE.md.Impact
This changes chat routing in the Rust web-chat session builder, the desktop/web composer’s normal and queued follow-up send paths, and the shared managed factory’s LocalOnly inference guard. Explicit provider/model selections now control the chat turn; an unset composer selection delegates to the persisted core default. Turn-local routing preserves the saved configuration through an effective clone.
Startup retains its existing local-model allowlist, Gemma fallback and 4096-token context limit.

JSON-RPC: the expanded test passed on the same warm conversation with a persisted BYOK provider. It covers a concrete managed picker selection and two saved managed defaults, asserting the outgoing managed path, model and backend credential while the saved BYOK binding stays unchanged.
