pySim's lchan.select() resolves names against global selectables (self +
parent chain + MF children + applications) and falls back to probe_file(),
which blindly SELECTs an unknown FID and permanently injects a dynamically
named DF.XXXX/EF.XXXX into the running filesystem model. Probing a whole tree
or scanning a snapshot with custom files therefore polluted the model, made
tree branches show children of the wrong object, and could persist phantom
files into snapshots.
- server: new _select_with_parent()/_select_path() walk the requested parent
path (new parent_path field, parent_sel kept as legacy fallback) strictly
through the model and call lchan.select_file() only; model-unknown 4-hex
segments are probed only with allow_probe and the temporary child pySim
adds is detached again via the cleanup callable that the four handlers
(/api/tree|select|read|write) now run in a finally block
- frontend: getParentPath() builds the segment chain (MF, ADF names, FIDs)
and all tree/select/read/write bodies plus the snapshot/profile walker send
parent_path; allow_probe is set only for custom files; the blind retries
in the file manager were dropped
- tests: tests/test_select_scope.py (duplicate-FID resolution, no APDU for
unknown non-custom files, probe+detach, model unchanged); fs_load/fs_probe
assertions for parent_path and allow_probe; docs/api.md and AGENTS.md
document the contract; SW cache v117 -> v118.
