 ## Key pydantic/SQLModel schemas (`models/llm/request.py`)
 - `LLMCallConfig` — one-of: saved reference (`id` + `version`) XOR ad-hoc `blob` (validator-enforced)
-- `ConfigBlob` — `completion` + optional `prompt_template` (`PromptTemplate.template`, plain string; `{{input}}` interpolation is llm-chain-only) + `input_guardrails`/`output_guardrails`. Each guardrail entry is either a `Validator` reference (`{validator_config_id}`) or an `InlineValidator` spec (`{type, on_fail, ...per-type params}`, `type` limited to `InlineValidatorTypeEnum`: gender_assumption_bias, pii_remover, profanity_free, topic_relevance_llm); tagged union `GuardrailEntry`. Both carry `is_enabled` (default true). Disabled entries are never fetched or sent. `services/llm/guardrails.apply_guardrails` POSTs fetched reference rows plus inline specs (a blob is all-refs or all-inline), with `is_enabled` stripped and `stage` stamped on inline specs.
+- `ConfigBlob` — `completion` + optional `prompt_template` (`PromptTemplate.template`, plain string; `{{input}}` interpolation is llm-chain-only) + `input_guardrails`/`output_guardrails`.

 - `CompletionConfig` — discriminated union on `provider`: `KaapiCompletionConfig` (standardized params: `TextLLMParams`/`STTLLMParams`/`TTSLLMParams`), `NativeCompletionConfig` (pass-through), `ProxyCompletionConfig` (client's own endpoint)
 - `TextLLMParams` reasoning knobs: `reasoning` + `effort` (OpenAI-style), `thinking` (Anthropic adaptive-thinking container, forwarded as-is) and `thinking_level` (Gemini). A knob must be **declared here** to survive config save — pydantic's default extra policy is ignore, so an undeclared key is dropped silently at validation with no error.
 - `QueryParams` — per-call input + `ConversationConfig`
