+ * `/a/link -> /a/docs/sub`), a purely string-level comparison would allow the
+ * paste and the recursive transfer would rediscover its own output. When
+ * `resolvePath` is provided (SFTP realpath for remote connections, the local
+ * realpath bridge for local panes), both sides are resolved through the
+ * filesystem before comparing. If that resolution fails, the guard fails
+ * closed and blocks the paste rather than risking a runaway transfer.
+ *
+ * realpath also cannot see through bind mounts: two mount paths for the same
+ * directory resolve to different strings. When `statIdentity` is provided
+ * (local panes only — remote SFTP stats carry no dev/ino), both sides' stat
+ * identities are compared as a final check; equal identities block the paste.
