The Tenant.ConversationConfig field was marked deprecated when
CustomAgent (builtin-quick-answer) replaced the per-tenant defaults
path, but the JSONB column, GET/PUT KV handlers, write helpers and
read fall-throughs all stayed wired. This had two concrete failure
modes:
- Input-field.vue silently PUT-ed per-user model picks back into
/tenants/kv/conversation-config, which requires Admin+ — Viewers
and Contributors got a 403 every time they switched chat models.
- The same write also overwrote the tenant-shared default for every
other user, turning a per-user UX into a per-tenant footgun.
Remove the field, the struct, the validate helper, the PUT case and
the two dead Summary helpers in session/helpers.go. KnowledgeSearch
loses its tenant-conversation fallback (one chunk-tool reader); the
global config + hardcoded defaults still cover it. session_agent_qa
already required agents to declare their own rerank_model_id, so no
behaviour change there.
Frontend follows:
- Input-field.vue: per-user 'last selected chat model' moves to
localStorage, no API call.
- AgentEditorModal: defaults for builtin-quick-answer creation now
come from prompt-templates (system/context/rewrite/fallback) and
retrieval-config (top_k / threshold), the two endpoints that
actually own those settings now.
- AgentSettings.vue: orphan settings page with no router/import
referencing it; deleted.
- api/system: getConversationConfig / updateConversationConfig and
the ConversationConfig interface go away.
