# Decompose: js/ui/profileModalController.js

## Selection
Selected `js/ui/profileModalController.js` (6258 lines) because it is the largest grandfathered file not decomposed in the last 8 weeks.

## Plan
Extract two cohesive blocks related to DM functionality that are currently mixed into the main controller:

1. **DM Relay UI Logic** (`ProfileDmRelayBinder.js`)
   - `cacheDmRelayElements`
   - `bindDmRelayControls`
   - `refreshDmRelayPreferences`
   - `handlePublishDmRelayPreferences`
   - `updateDmPrivacyToggleForRecipient`
   - `setPrivacyToggleState`
   - `handleActiveDmIdentityChanged`

2. **DM Attachment Logic** (`ProfileDmAttachmentBinder.js`)
   - `renderAttachmentQueue`
   - `uploadAttachmentQueue`
   - `resolveLatestDirectMessageForRecipient`
   - `maybePublishTypingIndicator`

These functions heavily rely on `this.dmController` and `this.services`, suggesting they belong in dedicated helpers or the DM controller itself. Extracting them to binder modules allows preserving the `this` context via argument passing while reducing the main file size.

## Stats
- Original size: 6258 lines
- Target reduction: > 200 lines
