+For reference, the source code is in `~/src/rithik-b/PlaylistManager`.
+
+Here is how “add this map to a playlist” is wired in this repo.
+
+### 1. User clicks Add (opens the picker)
+
+The Add button on the level detail screen calls `AddPlaylistModalController.ShowModal()`:
+
+```64:70:PlaylistManager/UI/ViewControllers/LevelDetailButtonsViewController.cs
+        [UIAction("add-button-click")]
+        private void OpenAddModal()
+        {
+            addPlaylistController.ShowModal();
+        }
+```
+
+`ShowModal` parses the BSML if needed, opens the modal, and lists playlists from the default lib manager:
+
+```97:103:PlaylistManager/UI/ViewControllers/AddPlaylistModalController.cs
+        internal void ShowModal()
+        {
+            Parse();
+            parserParams.EmitEvent("close-modal");
+            parserParams.EmitEvent("open-modal");
+            ShowPlaylistsForManager(PlaylistLibUtils.playlistManager);
+        }
+```
+
+### 2. User picks a playlist row — that is where the map is actually added
+
+The real work is in `AddPlaylistModalController.OnCellSelect`: after navigating folders, choosing a playlist calls **`IPlaylist.Add(...)`** from **BeatSaberPlaylistsLib**, then persists and notifies:
+
+```165:204:PlaylistManager/UI/ViewControllers/AddPlaylistModalController.cs
+        [UIAction("select-cell")]
+        private void OnCellSelect(TableView tableView, int index)
+        {
+            playlistTableData.TableView.ClearSelection();
+            // Folder Selected
+            if (index < childManagers.Count)
+            {
+                ShowPlaylistsForManager(childManagers[index]);
+            }
+            else
+            {
+                index -= childManagers.Count;
+                var selectedPlaylist = childPlaylists[index];
+                IPlaylistSong playlistSong;
+                if (HighlightDifficulty)
+                {
+                    playlistSong = selectedPlaylist.Add(standardLevelDetailViewController.beatmapLevel, standardLevelDetailViewController.beatmapKey);
+                }
+                else
+                {
+                    playlistSong = selectedPlaylist.Add(standardLevelDetailViewController.beatmapLevel);
+                }
+                try
+                {
+                    selectedPlaylist.RaisePlaylistChanged();
+                    parentManager.StorePlaylist(selectedPlaylist);
+                    popupModalsController.ShowOkModal(modalTransform, string.Format("Song successfully added to {0}", selectedPlaylist.Title), null, animateParentCanvas: false);
+                    // TODO: Doesn't refresh the sprite.
+                    Events.RaisePlaylistSongAdded(playlistSong, selectedPlaylist);
+                }
+                catch (Exception e)
+                {
+                    popupModalsController.ShowOkModal(modalTransform, "An error occured while adding song to playlist.", null, animateParentCanvas: false);
+                    Plugin.Log.Critical(string.Format("An exception was thrown while adding a song to a playlist.\nException Message: {0}", e.Message));
+                }
+                finally
+                {
+                    ShowPlaylistsForManager(parentManager);
+                }
+            }
+        }
+```
+
+So:
+
+- **PlaylistManager code**: `AddPlaylistModalController.OnCellSelect` (orchestration, UI, `StorePlaylist`, `Events.RaisePlaylistSongAdded`).
+- **Library code**: `selectedPlaylist.Add(...)` — implementation of how the entry is stored lives in **BeatSaberPlaylistsLib** (`IPlaylist`), not in this repository.
+
+There is no other `.Add(` on a playlist for this flow in the grep results; removing a song is the parallel path in `LevelDetailButtonsViewController.RemoveSong()`.
