The generator, not just its results. It synthesises an almost-match sample from
each regex's own skeleton and uses every token-boundary prefix as a repeating
unit, so `[`, `[system]` and `[system](` are each probed as separate arms.
Committed because the next step depends on it: 0.3.2 swept the other detector
tables with hand-crafted rows, and this session showed that class of sweep
misses arms -- a generic-payload pass found only one of the two patterns here.
Docstring carries the caveat the script cannot enforce: the ratio is computed
from two points, so a hit near the noise floor is a coin flip. Post-fix it flags
sub-agent:delegate-bypass at x2.8; measured over four doublings the exponent is
0.96-1.05, i.e. linear, 0.2s at the cap. Re-measure before concluding.
Not part of the package -- docs/, stdlib-only, no effect on the wheel.
