Drew T 5be4c21480 feat(phase-29): SESSION-21 — the ×138 member sweep: 274 members from 3 exemplar cracks (R22 140/140)
- family_sweep --hseq over the 3 newly-banked exemplars: BANKED 274 member-matches / 137 failed
  across 137 overlays, for ~0 agent tokens. Session total: 3 exemplars + 274 members = 277 fns.
- THE STALE-MAP STEP, hit and handled: the first sweep returned "0 matched-exemplar families"
  because .run/family_hseq.json still listed the fresh cracks as draft-ov077. Regenerated
  (matched-sib families 60 -> 63) and the sweep found them — the documented bank-x1 -> regen ->
  sweep path (memory crack-wave-sweep-map-regen).
- §86 REPRODUCED CLEANLY: 2 of 3 families templated ~137/137; the third failed ~137/137. Not a
  rate — a BIMODALITY. One probe per family, then sweep or skip; never a blended pool average.
- R22 clean-fleet: extract-all 139/139, check-all 140 passed / 0 failed (second clean-tree
  verification this session). dedup 1886/0, C1 coverage 239,604/239,604, 0 NON_MATCHING (G4).
- FLEET 81.7 -> 81.9% instr · 89.52 -> 89.60% fn-count · distinct-code 69.3% UNCHANGED — correct
  and expected: these are h_seq PURE propagation-class families, and SESSION-20's routing rule says
  propagation moves only the DISPLAY metric (members were already counted once via their exemplar).
  To move RE-completeness, target byte-VARIANT families. Stated plainly so the next session picks
  targets by the metric it means to move.
- drive-by: family_sweep --help crashed (argparse %-expands help text; a literal "0%" needed "0%%").
