# Polish Agent Loop: Dead Letter Queue & Reflection Safety

**Goal:** Implement final polish for the Agent Cognitive Runtime loop based on code review feedback.

**Scope:**
1.  **Dead Letter Queue Limit:** Add `maxFailedEvents` config to `Neo.ai.agent.Loop` and enforce a FIFO limit on the `failedEvents` array to prevent unbounded growth.
2.  **Reflection Safety:** Wrap the `reflect()` method logic in a try-catch block to ensure that non-fatal errors (e.g., memory storage failure) do not crash the main loop.

**Context:** Follow-up to Issue #7969 and code review feedback.

**Success Criteria:**
- `failedEvents` array never exceeds `maxFailedEvents` (default 100).
- `reflect()` method catches errors and logs a warning instead of throwing.
- `Loop.mjs` passes updated verification tests.

**Dependencies:** None.
