Specification for the first transmission through real hardware. The
project has no TX call anywhere across Lab001-Lab041, so the whole chain
exists but has never been connected to a transmitter.
Scope is deliberately minimal: get a JPEG through a cable loopback on a
single PlutoSDR and see the picture. Single device means TX and RX share
a reference clock, which removes the carrier offset and clock drift that
the receiver chain handles weakest.
- reuse Lab018 signal parameters unchanged, so hardware is the only new
variable
- reuse image_fragments, packet, build_radio_frame, find_radio_frame
- list the first-time traps: cyclic TX buffer, sample scaling, RX started
after TX, undersized RX buffer, automatic gain, receiver saturation
- define acceptance criteria and required measurements
- state explicitly what is out of scope: retransmission, erasure coding,
higher rate, two devices, over-the-air

Introduce tools/quick_gate.py: a one-second check that parses every file
in protocol, tests and tools, imports each protocol module, and runs the
functional tests of the labs that need no experiment data.
Wire it to a PostToolUse hook so edits under protocol or tests are checked
automatically, and add two read-only review agents with slash commands that
drive them: verifier for independent re-derivation of results, adversary for
unsafe-state hunting in control, failsafe, session and reset code.

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.
