mars-terminal 0.4.0

//! The no-`memory` build of [`crate::retrieval`]: same facade, neutral values.
//! This file is what makes the memory subsystem deletion-proof — every consumer
//! (agent prompt assembly, the accept hook, the management actions, the REC
//! chip) degrades gracefully through these stubs with zero `cfg` at call sites.
//! Keep it mirroring the facade section of `retrieval.rs`; both builds must
//! pass `--selfcheck` (see AGENTS.md).
