+# Task Log: docs-code-investigator
+
+**Date:** 2026-02-14
+**Agent:** docs-code-investigator
+**Target:** `js/ui/profileModalController.js`
+
+## Summary
+The agent successfully analyzed and documented `js/ui/profileModalController.js`, the largest UI controller in the codebase (~6200 lines). This file acts as the central orchestrator for the Profile Modal (dashboard).
+
+## Changes
+1.  **Overview Document**: Created `docs/profileModalController-overview.md` explaining the "Facade Pattern" architecture, sub-controller delegation, and state management flow.
+2.  **JSDoc**: Added comprehensive JSDoc blocks to the class and its critical public methods:
+    *   `constructor`
+    *   `load()`
+    *   `show()` / `hide()`
+    *   `handleAuthLogin()` / `handleAuthLogout()`
+    *   `handleAddProfile()`
+    *   `switchProfile()`
+    *   `renderSavedProfiles()`
+3.  **Context**: Updated `context/CONTEXT_<timestamp>.md` to reflect the pivot from `js/nostr/client.js` (which was already well-documented) to `profileModalController.js`.
+
+## Verification
+- **Lint**: Passed (with expected asset-manifest skip).
+- **Tests**: `npm run test:unit:shard1` passed (includes `tests/profile-modal-controller.test.mjs` implicitly or related components).
+
+## Next Steps
+- Consider breaking down `ProfileModalController` further as identified in the architectural overview.
+- Add JSDoc to the sub-controllers (e.g., `ProfileDirectMessageController`) in future runs.
