 ### Changes
 
+- Plugins/install: allow `OPENCLAW_PLUGIN_STAGE_DIR` to contain layered runtime-dependency roots, resolving read-only preinstalled deps before installing missing deps into the final writable root. Fixes #72396. Thanks @liorb-mountapps.
 - Control UI: polish the quick settings dashboard grid so common cards align across desktop, tablet, and mobile layouts without wasting horizontal space. Thanks @BunsDev.
 - Matrix/E2EE: add `openclaw matrix encryption setup` to enable Matrix encryption, bootstrap recovery, and print verification status from one setup flow. Thanks @gumadeiras.
 - Agents/compaction: add an opt-in `agents.defaults.compaction.maxActiveTranscriptBytes` preflight trigger that runs normal local compaction when the active JSONL grows too large, requiring transcript rotation so successful compaction moves future turns onto a smaller successor file instead of raw byte-splitting history. Thanks @vincentkoc.

 - `--fix` (alias for `--repair`) writes a backup to `~/.openclaw/openclaw.json.bak` and drops unknown config keys, listing each removal.
 - State integrity checks now detect orphan transcript files in the sessions directory and can archive them as `.deleted.<timestamp>` to reclaim space safely.
 - Doctor also scans `~/.openclaw/cron/jobs.json` (or `cron.store`) for legacy cron job shapes and can rewrite them in place before the scheduler has to auto-normalize them at runtime.
-- Doctor repairs missing bundled plugin runtime dependencies without writing into packaged global installs. For root-owned npm installs or hardened systemd units, set `OPENCLAW_PLUGIN_STAGE_DIR` to a writable directory such as `/var/lib/openclaw/plugin-runtime-deps`.
+- Doctor repairs missing bundled plugin runtime dependencies without writing into packaged global installs. For root-owned npm installs or hardened systemd units, set `OPENCLAW_PLUGIN_STAGE_DIR` to a writable directory such as `/var/lib/openclaw/plugin-runtime-deps`; it can also be a path-list such as `/opt/openclaw/plugin-runtime-deps:/var/lib/openclaw/plugin-runtime-deps`, where earlier roots are read-only lookup layers and the final root is the repair target.
 - Set `OPENCLAW_SERVICE_REPAIR_POLICY=external` when another supervisor owns the gateway lifecycle. Doctor still reports gateway/service health and applies non-service repairs, but skips service install/start/restart/bootstrap and legacy service cleanup.
 - Doctor auto-migrates legacy flat Talk config (`talk.voiceId`, `talk.modelId`, and friends) into `talk.provider` + `talk.providers.<provider>`.
 - Repeat `doctor --fix` runs no longer report/apply Talk normalization when the only difference is object key order.

+    `OPENCLAW_PLUGIN_STAGE_DIR` also accepts a path list. OpenClaw resolves bundled plugin runtime dependencies left-to-right across the listed roots, treats earlier roots as read-only preinstalled layers, and installs or repairs only into the final writable root:
+
+    ```ini
+    Environment=OPENCLAW_PLUGIN_STAGE_DIR=/opt/openclaw/plugin-runtime-deps:/var/lib/openclaw/plugin-runtime-deps
+    ReadWritePaths=/var/lib/openclaw /home/openclaw/.openclaw /tmp
+    ```
+
     If `OPENCLAW_PLUGIN_STAGE_DIR` is not set, OpenClaw uses `$STATE_DIRECTORY` when systemd provides it, then falls back to `~/.openclaw/plugin-runtime-deps`. The repair step treats that stage as an OpenClaw-owned local package root and ignores user npm prefix and global settings, so global-install npm config does not redirect bundled plugin dependencies into `~/node_modules` or the global package tree.
