memory_recall
Cue-based recall — returns hits **and anti-hits**: memories that *contradict* the cue surface next to the ones that match, so a stale fact can't masquerade as current.
memory_temporal_recall
Time-anchored recall — *"what did I say about pricing in May?"*
memory_recall_structural
Retrieve by the *shape* of a memory (the HD substrate), not just its embedding.
memory_search
Plain text search over the store.
memory_capture
Write a memory explicitly (ambient capture normally does this for you).
memory_contradict
Record that a fact changed. The old version is archived, not erased — both stay retrievable. That's the Rescue@10 and historical-verbatim story in the [benchmarks](#benchmarks).
memory_reinforce
Strengthen a memory's recall pathways.
memory_consolidate
Run a consolidation pass now instead of waiting for idle.
profile_get_set
The eleven sealed procedural knobs the engine learns about you.
