Enum ContextBudgetSource 

pub enum ContextBudgetSource {
    AutoDetected(usize),
    Configured,
    Fallback,
}

How the effective context-token budget was determined by resolve_context_budget_tokens.

Callers use this to choose a diagnostic log message appropriate to their call site (initial startup vs. config hot-reload) while sharing the same resolution algorithm.

Variants

AutoDetected(usize)

Auto-detected from the provider’s advertised context window.

Configured

Explicit memory.context_budget_tokens config value, or auto_budget disabled.

Fallback

Neither the config nor the provider yielded a usable value; the hardcoded fallback was used.
