Module llm_overrides 

Session-scoped LLM override resolution helpers.

This module centralizes the business logic for applying a per-session provider/model override (see crate::agent_sessions::SessionLlmConfig) to an in-memory crate::config::AppConfig.

Goals:

• Keep GUI/CLI thin (they provide session data + platform-specific secret lookup).
• Ensure provider/model precedence and compatibility checks are consistent.

Structs

EffectiveLlmConfig

The effective provider/model after applying session overrides.

Constants

KNOWN_LLM_PROVIDERS

Known LLM provider identifiers.

Functions

apply_basic_mode_session_llm_overrides

Apply session-scoped LLM overrides (for basic/non-TUI CLI mode) and return a cloned config together with the effective provider/model.

apply_cli_llm_overrides

Apply CLI-provided provider and/or model overrides to an in-memory config.

apply_cli_model_arg_overrides

Apply a CLI --model argument to the config.

apply_cli_provider_arg_override

Apply a CLI --provider argument to the config.

apply_cli_session_llm_overrides

Apply session-style LLM overrides for CLI adapters.

apply_session_llm_overrides

Apply session-scoped LLM overrides to an in-memory config and return the effective provider/model.

is_known_llm_provider

Returns true when provider matches one of the KNOWN_LLM_PROVIDERS (case-insensitive comparison).

normalize_session_llm_override

Normalize and (optionally) migrate session-scoped LLM selection state.

parse_model_selector_legacy_aware

Parse a legacy-aware selector string into a session override.

resolve_session_llm_override

Resolve the session-scoped LLM override from an AgentSession.

session_llm_config_from_cli_model_arg

Parse a CLI-style model selector (e.g. "provider:model" or "model") into a SessionLlmConfig.
