 /workspace` when it acquires or resumes a lease.
 `pr-14769-probe-remote-cwd.patch` is that PR's diff (head `10dc7371`).

+Claude auto memory is lost after every run (REN-541): it lives under
+`CLAUDE_CONFIG_DIR`, which Paperclip makes fresh per run and deletes.
+`ren-541-claude-auto-memory.patch` makes the ACPX engine write
+`autoMemoryDirectory: <AGENT_HOME>/memory` into the per-run
+`.claude/settings.local.json`. `AGENT_HOME` is restored before and saved after
+every run, local and in k8s pods. The value is not part of the session
+fingerprint, so resume is unchanged. No upstream PR yet; rename the patch to
+`pr-<n>-…` once there is one.
