+3. **User Mapping**: The container runs as the non-root `node` user (UID 1000).
+   If your archives are readable only by another account, run as that user
+   instead — the container needs to *list* the archive directory, so `--x`
+   (traverse-only) permissions are not enough:
    ```bash
-   docker run --user $(id -u):$(id -g) ...
+   docker run --user $(stat -c '%u:%g' /path/to/archives) ...
    ```
+   In Compose:
+   ```yaml
+   services:
+     instaarchive:
+       user: "1234:1234"   # a UID that can read your archives
+   ```
+
+### Archive Index
+
+On first start the server walks the archive root once and caches the result,
+keyed by directory mtime. This matters on network storage: for a 110k-file
+archive root, listing went from ~52s per request to ~0.1s. Mount a volume at
+`/cache` (or set `CACHE_DIR`) so the index survives restarts, otherwise it is
+rebuilt on every start.
