Drew T 687d761bde feat(phase-29): wave22 families swept 548/548 (R22 140/140) — parallel gating proven at scale
4 families x 137 members: BANKED 548 / 0 failed. R22 clean-fleet 140 passed / 0 failed of 140.
MEASURED: fn-count 318,859 -> 319,412 (+553); instr-weighted 84.4 -> 84.7% (+36,640 ins);
distinct-code 74.4 -> 74.5% (+134 unique fns).

TODAY'S PARALLEL GATE WIRING PROVED AT SCALE: this run reported `gating 411 group(s) across distinct
binaries, -j12`. When I shipped it earlier I could only smoke-test 4 fail-fast groups and said
explicitly that the 1.5x measured there was NOT the 8-16x claim; 411 full build-and-gate cycles is
the shape the claim was about.

A PERFECT 548/548 also says the wave's exemplars were right for the right reasons — a body that
templates across 137 byte-variant siblings with zero rejections is not a marginal match.

BAND NOTE: the first sweep attempt used --band substantial and staged NOTHING; these exemplars are
60-76 ins, i.e. the MID band (substantial is >=80). The tool reported that honestly
("0 matched-exemplar families (band=substantial); 0 candidate members") rather than returning a
clean-looking 0 banked — the skip-vs-result distinction this session kept running into.
