The live card references 6F06 from MF-tree files (MF/7F20/6F07 ->
8B 03 6F06 14), but the resolver compared only the path's first
segment: the reference fell back to the ADF.USIM copy instead of the
file's own DF copy (ISO 7816-4 5.4.3.3 / TS 102 221 9.2.7 walk-up) -
masked on this card only because all four copies are byte-identical.
- The server reads the DF.TELECOM and DF.GSM copies too (MF/7F10/6F06,
MF/7F20/6F06 - TS 51.011), best effort.
- fcpArrRules resolves by the file's DF chain (own DF first, then
walking up to MF); a reference with no copy in the chain resolves
only when a single candidate exists, otherwise it stays silent.
- The implicit form prefers the file's DF copy (6F06), walking up to
the MF copy (2F06).
Tests: the DF copy wins over the ADF copy; two candidates outside the
chain stay unresolved; a single one resolves; the implicit walk-up;
the server reads the DF-tree paths. 879 frontend + 858 Python;
