The recommended tap is the short cable with external pull resistors whose
pins are fixed and known in advance (D5=CLK, D0=I/O, D4=RST, D2=VCC), so
the auto-detection tool is no longer needed. Drop it and all references:
- Delete tools/detect_pins.py.
- README: replace the 'Detecting the wiring' section with a fixed-wiring
note; drop the Python/numpy prerequisite and the detect_pins capture
step from the Windows guide.
- setup.bat: remove the Python/numpy check and the 'find the wiring' next
step.
Full -A iso7816 printed all annotation rows including the per-byte 'bytes'
row (thousands of lines per capture; ~22k on xiaomi_phone, ~11k on A55).
Default is now '-A iso7816=apdus,iso7816=warnings' (decoded APDUs + decoder
warnings/errors only); --debug restores the full '-A iso7816' output plus
the existing -l 4. stderr decoder log (banner, PACKETEND hex, glitches,
discards) is untouched.
Residual CONCAT mis-frames (4gmodem/A55_sim2/S21p_sim2) traced to a silent
5-byte drop at an invalid-INS T=0 header (0x0f 00 a4 08 04). Drop only the
stray leading byte and re-frame the remaining four via _replay so the real
command (00 a4 08 04 02 2f 00 -> 61 1c) is recovered.
- _note_discard()/_consume_first(): every consumed-but-unemitted byte is
now logged; idle 0x00/0xFF discards are rate-limited, real data always
gets an ANN_WARN annotation.
- All read-until-SW loops log skipped non-SW bytes.
- All traces: CONCAT 0; BAD_FCS/GARBAGE 0; test_8/test_7 RESULT OK;
47/47 unit tests; baseline byte-identical.
History rewritten to a single root commit so no example trace is stored
in the repo (fixtures are local-only, gitignored). README keeps only
generic <trace>.sr placeholders; AGENTS.md retains the fixture names.
