# mempalace_manager Abstract memory API — backend-neutral wrapper. ## Operations - `mem.put(partition, key, value, metadata?)` - `mem.get(partition, key)` - `mem.query(partition, filter)` - `mem.search(partition, query, top_k)` — semantic - `mem.delete(partition, key)` - `mem.list(partition, prefix)` - `mem.compact(partition)` — AAAK recompression - `mem.snapshot(partition, path)`, `mem.restore(partition, path)` - `mem.with_project(id, fn)` — scoped access - `mem.lift(key)` — explicit global read from local context (logged) ## I/O Contract ```yaml io_contract: input: { op, partition, args } output: { result } idempotent: depends side_effects: [fs] ``` ## Safety - Partition scoping enforced — cross-scope reads require `with_project()` or `lift()`. - Constitutional invariant: `isolation_strict` cannot be disabled. - Selects backend via `memory.config.backend` (mempalace|sqlite|filesystem|custom).
