 **Body capture limits:** finite bodies with known `Content-Length` up to 32 MiB are buffered then previewed at 2 MiB (text view capped at 256 KiB). Larger known-length bodies are **not captured** so downloads are not stalled. Bodies with **no declared length** (chunked, HTTP/2 without `Content-Length`, SSE) are never buffered, whatever their content type: they are relayed untouched and the first 2 MiB is previewed live (decoded for gzip/deflate/br), so large downloads/uploads of unknown size (for example a `git clone`) are not aborted by the buffer limit. Size column shows the original length when known.

 ## Advanced
 
+### Session retention and clearing
+
+**Options → Session retention…** sets how many sessions stay in the list and how much disk the saved HAR files may use. Each Inspector run writes into a timestamped folder under the session cache (local application data, `TitaniumInspector/session-cache`). The folder is created on the first captured session, so a run that captures nothing does not leave an empty folder.
+
+The list limit and the disk limit are separate:
+
+| Action | List | Current run on disk | Earlier runs on disk |
+|--------|------|---------------------|----------------------|
+| List is over **Maximum sessions to keep** | Oldest rows leave the list | Those rows stay as HAR files | Unchanged |
+| Over **Disk space for saved sessions** | Rows stay; missing bodies show a hint | Oldest HAR files go first, across every run | Same. An emptied run folder is deleted |
+| **Capture → Clear sessions** | Cleared | Deleted, including rows the list limit already hid | Kept, so you can import them from the cache folder |
+| **Clear saved session cache…** | Kept | Deleted after you confirm the run count and size | Deleted |
+
+**Clear sessions** does not ask for confirmation. The status line reports how much disk it freed. **Clear saved session cache…** is on the Session retention window, next to **Open cache folder**, and asks before it deletes. Sessions stay in the list, but their saved bodies are removed. New captures use a fresh run folder.
+
 ### Excluded hosts
 
 **Options → Excluded hosts…** edits OS bypass, tunnel-only, and auto-tunnel learning. **Capture → Capture local traffic** controls whether loopback uses the system proxy (not a host list).
