The extract_unit fix (commit:0552) revealed 82 families with a genuinely-matched exemplar and UNSWEPT
siblings (~2.03M templatable bytes) — mostly exemplars cracked AFTER the session-2/3 mechanical band
sweeps ran (the giant campaign + recent cores), so the sweep had simply never seen them.
- re-ran `family_sweep --hseq --band substantial` on a regenerated manifest: 29 matched-exemplar
families, 1046 member drafts staged, 1643 correctly skipped as pinned-exemplar.
- BANKED 266 member-matches / 780 gate-rejected. The whole-binary byte-gate (G3/P9) arbitrated every
one; R22 clean-fleet 136/136 BYTE-IDENTICAL from `make clean`.
- metrics: instr-weighted 63.6 -> 63.8%; distinct-code 40.5 -> 40.7%; fn-count 82.39%.
The 780 gate-rejections are the next lever: family_sweep's h_seq path does NOT yet carry the §8d
`scoped` stage (it prepends carried data externs at FILE scope, the exact class that blocked the jr
sweeps), so a large share are expected to be the same decl-environment conflict. Investigated next.
