When a /model switch resolves a valid model but the in-place agent swap fails mid-conversation (expired key, unreachable base_url), the agent rolls itself back to the old working model+client and re-raises. The callers caught that re-raise, logged a warning, then committed the broken switch anyway: wrote the failed model to the session DB, set _session_model_overrides to the broken model/provider/key, and (gateway direct path) evicted the working cached agent. The next message then rebuilt a dead agent from the broken override -> permanently unusable conversation (#50163). Fix the whole caller class so a failed swap aborts the commit entirely: - gateway/slash_commands.py (picker + direct /model paths): on swap failure, early-return an error message; skip DB persist, session override, cache eviction, and config write. - cli.py (both /model handlers): snapshot CLI-level credential/runtime fields before mutating, restore them on swap failure, and abort the note + success print. - tui_gateway/server.py: wrap the previously-unguarded swap; on failure raise a clean error and skip worker restart, runtime persist, switch marker, session model_override, and config persist. The no-cached-agent path (apply-on-next-session) is unaffected. Adds a gateway regression test that fails on the pre-fix behavior. |
