EF_PBR ('4F30', TS 31.102 4.4.2.1) lists the phonebook's files as
BER-TLVs, and those files are not in pySim's model - so they were
invisible in the file tree.
- The PWA gains the decoder (efDecPbr, registered as EF.PBR/4f30): the
'A8'/'A9'/'AA' type-1/2/3 containers, the 'C0'-'CC' kinds, the 02/03
value lengths (FID / FID+SFI) and the master EF (the first FID after
the first 'A8'), tolerant of FF padding, truncation, unknown tags and
the spec's vague 'AA' path form (kept raw + noted, never a throw).
- The server reads the three PBR copies once per card session
(best-effort, exactly like EF.ARR) into server.pbr and serves the raw
records from the card-free GET /api/pbr.
- The file tree is populated SERVER-SIDE (no frontend involvement): a
small Python parser reads the cached records and /api/tree appends the
referenced files as children of the DF that holds the PBR
({'name','fid','isDir':false,'pbr':true,'sfi'}, deduplicated against
the model), and /api/tree|select|read|write auto-allow the probe for
exactly those FIDs, so the injected nodes are clickable without any
PWA flag. The node-to-PBR match is by the requested node's normalised
path: a leading MF before an ADF segment is dropped and an ADF
addressed by AID (the Profiler's walk) folds onto its name, so both
DF_PHONEBOOK copies resolve to their own PBR; a full path never falls
back to another DF's copy, and an ambiguous bare 5F3A injects nothing.
- Drift guard: the JS and Python parsers share
frontend/tests/pbr_vectors.json, which includes the TS 31.102 Annex G
record (its printed A8 length is internally inconsistent - 10
primitives x 5 bytes = 0x32, not the printed 0x2D - so the corrected
length is used, noted in the case name).
