56 fast checks, 0.2 s, covering packet.py and the new bpsk_radio.py.
test_bpsk_radio exists mainly to prove the extraction changed nothing. It
loads the original function definitions out of Lab018, Lab019 and Lab023
in isolation, compiling only the wanted AST nodes so the labs' module
level file writing never runs, then compares outputs: bit conversion,
modulation, shaping filter, frame marker and the carrier estimator over
random phase and frequency offsets.
It also covers the frame functions written fresh for the module:
roundtrip at four payload sizes, size and type rejection, broken sync
word, truncation, carrying a real CRC32 packet, and a shaped-signal
search that recovers the packet through matched filtering.
test_packet covers roundtrip across all four message types and five
payload sizes, sync word, length arithmetic, sequence range, truncation,
oversized payload, and single-bit corruption at six positions, which is
the property CRC32 is there to provide.

The tests/ directory held 50 laboratory programs and no tests. They model
channels, run hundreds of repetitions and write CSV, PNG and reports;
calling that a test suite blocked introducing a real one, because any
pytest run would have collected the labs and re-executed every
experiment.
- move all 50 lab programs to experiments/ with git mv, preserving history
- rewrite the 38 cross-imports between labs from tests.labNNN to
experiments.labNNN
- leave tests/ empty for actual fast checks of protocol/
- point quick_gate and the hook at the new layout and add experiments/ to
the syntax sweep
- update the paths quoted in the Lab042 specification and the verifier
agent definition
This also defuses the import-time work finding without touching 41 files:
the labs still create directories and write files on import, but nothing
imports them now except the gate, which does so deliberately.
Gate passes: syntax clean, protocol imports, 15 lab modules import, 2
functional suites run.

Audit found seven numbers in simulate_trial that were neither modelled by
Lab041 nor traceable to their claimed source. Video fraction 0.910 did not
match Lab040 (0.9603); base queue length 31 did not match Lab040 (36-38).
- drop video/telemetry/control delivered fractions and queue length: these
belong to Lab037 and Lab040 and are not modelled here
- drop lab041_traffic_impact.png, which plotted only those metrics
- drop negative_speed_cases and speed_limit_exceeded_cases, never computed,
along with the tautological asserts that checked them
- bind braking parameters to the Lab039 nominal profile via named constants
instead of the literals 0.250 and the divisor 6.0
- cite Lab038 as the source of the transferred video and telemetry loads
- rewrite the invariants section: nine architecture-derived properties now
carry functional-check references, five unmeasurable ones move to their
own section
- extend check 04 with negative speed and the 15 m/s boundary
- state explicitly what the matrix rolls, what the architecture fixes and
what is not modelled at all
Regenerated: 180 combinations, 24/24 checks, five CSV and seven PNG.
Six columns removed, no retained value changed.
