Struct SubprocessStats 

pub struct SubprocessStats {
    pub usage_ptr: Option<String>,
    pub model_ptr: Option<String>,
    pub num_turns_ptr: Option<String>,
}

Declarative stats extraction for a SubprocessOutput — JSON Pointers (RFC 6901) into the parsed stdout, mirroring the result_ptr idiom. Lets a declared CLI backend (e.g. claude -p --output-format json, codex exec --json) surface token usage without any engine-side backend branch. Same IN-immutability discipline as the rest of this crate: pointers only, no logic.

Fields

usage_ptr: Option<String>

JSON Pointer selecting a usage OBJECT out of the parsed stdout. The engine reads input_tokens/output_tokens (falling back to the OpenAI-style prompt_tokens/completion_tokens spelling) and an optional total_tokens from it.

model_ptr: Option<String>

JSON Pointer selecting the model name STRING that actually served the run (overrides the template’s declared {model} value in the recorded stats when present).

num_turns_ptr: Option<String>

JSON Pointer selecting the number of LLM turns (a JSON number).
