41/// Tracks in-flight eval sessions: session_id → strategy name.
42///
43/// Kept between `alc_eval` invocation and eventual completion (which may
44/// arrive via `alc_continue` after LLM round-trips). Used by
45/// `run.rs::maybe_save_eval` to persist the result to `~/.algocline/evals/`.
46/// Card emission is handled by `alc.eval()` Lua-side — no Rust tracking needed.
47///
48/// `std::sync::Mutex` is used (not tokio) because all operations are
49/// single HashMap insert/remove/get completing in microseconds, and no
50/// `.await` is held across the lock. Poison is silently skipped.

52
53/// Tracks session_id → strategy name for all strategy-based sessions (advice, eval).
54///
55/// Same locking rationale as `EvalSessions`. Used by `alc_status` and
56/// transcript logging. Poison is silently skipped — strategy name is
57/// non-critical metadata for observability.
