## What

Reconstructed corrupted FXA-2166 (CHG: Extract Invoke Index Update Helper) from companion PRP FXA-2165. Restored What/Why/Steps sections and added missing Change History table.

## Why

FXA-2166 had garbled body text and failed `af validate` ("Missing Change History table"). Document was unusable as a change record.

## Impact Analysis

- **Systems affected:** FXA-2166 only (document fix, no code changes)
- **Rollback plan:** `git checkout HEAD -- rules/FXA-2166-*.md`
