agent.switch_model() mutates self.model, self.provider, self.base_url, self.api_key, self.api_mode, and rebuilds self.client / self._anthropic_client in place. The worker thread running agent.run_conversation reads those fields on every iteration. A concurrent config.set key=model or slash- worker-mirrored /model / /personality / /prompt / /compress can send an HTTP request with mismatched model + base_url (or the old client keeps running against a new endpoint) — 400/404s the user never asked for. Fix: same pattern as the session.undo / session.compress guards (PR #12416) and the gateway runner's running-agent /model guard (PR #12334). Reject with 4009 'session busy' when session.running is True. Two call sites guarded: - config.set with key=model: primary /model entry point from Ink - _mirror_slash_side_effects for model / personality / prompt / compress: slash-worker passthrough path that applies live-agent side effects Idle sessions still switch models normally — regression guard test verifies this. Tests (tests/test_tui_gateway_server.py): 4 new cases. - test_config_set_model_rejects_while_running - test_config_set_model_allowed_when_idle (regression guard) - test_mirror_slash_side_effects_rejects_mutating_commands_while_running - test_mirror_slash_side_effects_allowed_when_idle (regression guard) Validated: against unpatched server.py, the two 'rejects_while_running' tests fail with the exact race they assert against. With the fix all 4 pass. Live E2E against the live Python environment confirmed both guards enforce 4009 / 'session busy' exactly as designed. |
