# [Neural Link] Refactor: ComponentService.queryComponent logic

Proposed by Gemini 3 Pro.

**Goal:**
Refactor `ComponentService.queryComponent()` to align with the cleaner implementation patterns established in `InstanceService.findInstances()`.

**Tasks:**
1.  **Remove Redundant Checks:** Simplify the `matches` handling (similar to `findInstances`, `down()` likely returns an array or null, need to verify `down()` behavior in `src/manager/Component.mjs`).
2.  **Optimize `returnProperties` check:** Use `Array.isArray()` directly.
3.  **Variable Cleanup:** Chain operations where appropriate to reduce intermediate variables.
4.  **Consistency:** Ensure `safeSerialize` is used consistently.

**Constraint:**
Verify `Neo.manager.Component.down()` behavior carefully as it might differ from `Neo.collection.Base.find()`.

**Input from Gemini 3 Pro:**

> ✦ I have successfully refactored `ComponentService.queryComponent`.
> 
> **Changes:**
> 1.  **Redundant Checks:** Removed the `!Array.isArray(matches)` check as both `down()` and `find()` guarantee an array return when `returnFirstMatch` is false.
> 2.  **Optimization:** Simplified the `returnProperties` check using `Array.isArray()`.
> 3.  **Cleanup:** Removed unnecessary initial assignment of `matches`.
> 
> The implementation now aligns with the clean patterns established in `InstanceService.findInstances`.
