Module field_validator 

Key-value validation for configuration service.

This module handles the validation logic that was previously embedded in ProductionConfigService::validate_and_set_value. It provides field-specific validation for configuration keys and values.

Architecture

• crate::config::validation - Low-level validation functions for individual values
• crate::config::validator - High-level configuration section validators
• crate::config::field_validator (this module) - Key-value validation for configuration service

Functions

get_field_description

Get a user-friendly description for a configuration field.

normalize_ai_provider

Normalize an ai.provider value to its canonical form.

validate_all_fields

Validate every field of a fully-deserialized Config using the same per-key rules as validate_field. This is used by ConfigService::load_for_repair so that a TOML-parsed but strict-invalid config still has its individual field invariants enforced before being handed to the config set/get/list handlers.

validate_field

Validate and parse a configuration field based on its key.
