Per-session /model overrides (_session_model_overrides) were in-memory only, so a gateway restart silently reverted every session to the global default model. Persist the non-secret parts (model/provider/base_url ONLY — never api_key) into the session entry in sessions.json and lazily rehydrate them on first use after a restart, re-resolving credentials through the normal runtime provider resolution. - gateway/session.py: SessionEntry.model_override field with sanitize_model_override() (allowlist: model/provider/base_url) applied on both serialization and deserialization; SessionStore.set_model_override / get_model_override accessors. reset_session() already creates a fresh entry, so /new keeps its clear-on-reset semantics — a restart cannot resurrect an override the user reset away. - gateway/slash_commands.py: write-through at both /model set sites (text command + picker) after storing the in-memory override. - gateway/run.py: _rehydrate_session_model_override() called from _resolve_session_agent_runtime(); in-memory state always wins, credentials are re-resolved per provider (credential-less fallback on failure). Session expiry finalization also drops the persisted override. - tests/gateway/test_session_model_override_persistence.py: restart round-trip, /new clearing, api_key-never-serialized (including tampered sessions.json), rehydration + live-state precedence + credential-failure degradation. Salvaged from #3659 by @Git-on-my-level, narrowed to the restart-persistence gap confirmed in triage. |
