/oic/res's baseline-Interface response only lists resources with the
discoverable policy bit set, and a real dump (issue #177 follow-up,
TP1X_REF_21K) confirms /device/0's whole x.com.samsung.da.* tree is
registered without it -- so a second logical Device's Collection, if
one exists, would be just as invisible to /oic/res as /device/0 is.
Probe /device/1 and /device/2 directly instead: a plain non-mutating
RETRIEVE, tolerated-404 same as every other speculative read in this
module. Parsed with the same parse_device0_batch used for /device/0
itself, and folded into identity.raw so diagnostics can tell "checked,
found nothing" apart from "never checked".
