# Summary of Changes: Loop Name Features

**Date**: 2026-02-03
**Status**: Archived

## Overview
This archive contains the specifications and proposals for the Loop Name Enrichment and Auto-Generation features. These features enhance the RCU Action Server by enriching event data with descriptive loop names derived from project metadata or fallback generation logic.

## Included Changes

### 1. [Feature: Loop Name Enrichment](./feature-loop-name-enrichment.md)
- **Goal**: Enrich `rcu_action_events` with `loop_name` by looking up cached metadata from `temporary_project` tables.
- **Key Components**:
  - `ProjectMetadataCache`: Loads rooms and loops data daily.
  - `loop_name` column added to `rcu_action_events` table.
  - Processor logic updated to perform lookup.

### 2. [Feature: Feature Toggle Loop Name Generation](./feature-toggle-loop-name-generation.md)
- **Goal**: Provide a configuration switch to control the fallback behavior when cache lookup fails.
- **Key Components**:
  - `ENABLE_LOOP_NAME_AUTO_GENERATION` env var.
  - Logic to generate `[Type-Addr-Loop]` format only if enabled.
  - Default behavior is `true` (enabled).

## Implementation Status
- All proposed features have been implemented and verified via unit tests.
- Configuration variables are documented in `.env.example`.
