+| Create | `crates/mem-core/src/gated_loop.rs` — `run_loop()`, `LoopConfig`, `LoopEvent`, `RunOutcome` |
+| Modify | `crates/mem-core/src/lib.rs` — add `pub mod gated_loop;` and re-exports |
+| Create | `tests/it_gated_loop.rs` — integration tests (workspace root, 10 assertions) |

+## Dependencies

+| Crate | Where | Already present? |
+|---|---|---|
+| `async-trait` | `crates/mem-core/Cargo.toml` | ❌ add — for `LlmClient` trait |

+Or use `impl Future` return types and avoid the dependency.

+## Existing code to reuse

+- `Chunk`, `Level`, `Sha256Hash` from `domain.rs` — input/output types
+- `Query` from `query.rs` (M1.2) — the standing question
+- `PromptBuilder` from `prompt.rs` (M1.3) — assemble the prompt per turn
+- `parse_gate_response` from `gate_parser.rs` (M1.4) — parse LLM output
+- `ChatClient` from `mem-llm/src/chat.rs` (M1.1) — call the LLM
+- `TokenCounter` from `mem-chunk/src/token_counter.rs` — measure candidate memory tokens
+
+## Dependency injection
+
+The loop needs an LLM client, but tests must use a scripted fake. Define a trait:
+```rust
+// in gated_loop.rs
+pub trait LlmClient: Send + Sync {
+    fn complete(&self, system: &str, user: &str, max_tokens: usize)
+        -> impl std::future::Future<Output = anyhow::Result<mem_llm::Completion>> + Send;
+}
+```
+`ChatClient` implements it. Tests use a `ScriptedClient` that returns canned
+responses indexed by turn number.
