-# Prevents unnecessary symlink flips when no transcoding is happening
+# ━━━ Transcode Server Array ━━━
+# All media servers that share the ramdisk transcode space.
+# transcode_manager.sh reads this array and queries each server's API for active sessions.
+# Session display, storage detection, and threshold decisions cover ALL servers combined.
+#
+# One entry   → works exactly as before — single server behavior
+# Many entries → aggregates sessions from all servers, one threshold on total ramdisk usage
+#
+# Each server writes to its own subfolder inside transcoding-temp:
+#   /mnt/ram-transcode/transcoding-temp/ABC123/   ← Emby session
+#   /mnt/ram-transcode/transcoding-temp/XYZ789/   ← Jellyfin session
+# They never touch each other's files — the ramdisk is shared scratch space.
+#
+# Docker Extra Parameters — each media server container that uses the ramdisk needs:
+#   --mount type=bind,source=/mnt/ram-transcode,target=/ext-ram-transcode,bind-propagation=shared
+# The target path (/ext-ram-transcode) must match what's configured in each server's
+# transcoding settings. Use a different target path per container if needed.
+#
+# Format: "ContainerName|URL|APIKey|Type"
+#   ContainerName — exact Docker container name (used for running check)
+#   URL           — API base URL including port
+#   APIKey        — server API key (Emby/Jellyfin token, Plex token etc.)
+#   Type          — emby | jellyfin | plex (controls API endpoint format)
+#
+# The first entry is the primary server — used for container running check
+# (TRANSCODE_CHECK_EMBY still applies to first entry).
+# Additional entries are queried if their container is running.
+# Entries with placeholder APIKey values are skipped automatically.
+#
+# ⚠️  Tdarr does NOT belong here — Tdarr encodes full files, not HLS segments.
+#     Large working files would fill the ramdisk rapidly and cause constant flips.
+#     Keep Tdarr on SSD. Use tdarr_cleanup.sh for Tdarr orphan management.
