Add hunt-side live ETU recovery so a card already at a non-default F/D
(e.g. Samsung F=512/D=32 -> 16 CLK/bit) can be decoded without a 372-rate
ATR, and bound the all-0xFF hunt so an idle/unsyncable line can never loop
forever.
- _recover_etu_in_hunt(): measure the live ETU from DATA edges while still
in FIND START, then re-derive clock_skip; reuses _confirm_etu validation.
- _atr_hunt_failure_action(): pure recover/retry/resume_data decision, with
ATR_HUNT_ETU_ATTEMPTS=3 / ATR_HUNT_IDLE_RESETS=3 / ATR_HUNT_FAIL_LIMIT=12.
- Persistent counters reset only on a successful ATR parse (not RST re-arm),
so RST-cycling phones cannot starve the escape.
- 8 new unit tests (55 total).
Validated on the full trace suite (test_8 56/0/OK, test_7 65/0/OK, xiaomi
640, xiaomi_cold 473, 4gmodem 327, A55 407/395, S21p 399/375, target S21p
369; 0 CONCAT, RESULT: OK) with no regressions.
- pd.py: remove _lock_etu_from_edges (long-disabled) and the no-op
while-True FIND START wrapper.
- pd.py: re-raise SystemError (libsigrokdecode's clean EOF signal) in the
six 'except Exception: pass' guards so put()/wait() at end-of-capture
exits cleanly instead of being swallowed.
- pd.py: fix _measure_clock_period docstring (averages, not robust-min);
drop stale 'line 1633' comment; document the synthetic pcap UDP header
(zero IP checksum / fixed loopback+ports are intentional).
- signal_diagnostic.py: add --max-samples cap + document whole-capture
RAM cost; fix stale '--rst/--vcc=ignore' guidance (-> --no-rst/--no-vcc).
- tests: make test_valid_cla_interindustry_classes use subTest (was a
no-op tuple expression).
- start.sh/start.bat: note the -A multi-spec form is sigrok-cli 0.7.x.
- Remove stale tests/baseline_new.txt (v1.1.3-era, ATR-included mode).
- Add top-level LICENSE (GPL-2.0-or-later).
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.
