Drew T 79b7ff2cbf chore(phase-30 S49): wave 7b — adapt lane scaled, 44 banked (92% MATCH->bank); the TU-spread law
- thresholds relaxed to <=6 blocks/<=16 tokens UNION edit-fraction <=0.20: cards 518 -> 721,
  MIXED 310 -> 50 skeletons; the 753-ins func_8017BEBC (0.987 sim) became reachable.
- 59 cards -> 48 agent-MATCH (81%) -> 44 BANKED (92% MATCH->bank, 75% end-to-end), 6.9M tok.
- FINDING (the actionable one): 7b's bank rate crushed 7a's because it SPREAD 48 drafts over 35
  destination TUs; 7a's failures were per-TU declaration collisions between sibling drafts.
  Cookbook §169 updated with the spread law.
- R22 213/213 BYTE-IDENTICAL from clean; fleet 96.55% fn / 95.2% instr / 89.9% distinct;
  stubs 12,584 -> 12,535; dedup 2,035/0.
- incidents 3 & 4 recorded: an agent wrote a TRACKED header (guard caught it, prose is not
  enforcement); my own gate_lane filtered on the wrong key and printed 'gating 0 drafts' as a
  result (R32 silent skip) — fixed with a coverage assertion that refuses to report 0.

Phase 26 — h_seq family survey (T1)

Glossary — zero-crack in THIS file means n_matched == 0: the family has no matched member anywhere and needs its FIRST crack. (Roadmap §3 T3 uses the phrase for the OPPOSITE case — an already-matched exemplar awaiting propagation.)

Generated by tools/family_hseq.py from the 212 binary sigs + per-binary src stubs. Ranked by TEMPLATABLE byte-weight (PURE+IMM members × nins × 4). The byte-gate is the arbiter.

Scope (212 binaries): 141 location overlays + 70 md_ modules + the resident · MAIN IS EXCLUDED* · generated at HEAD commit:1803 · stub set derived from corpus.stubs — the same oracle progress.py counts, so same-tree overlay totals agree by construction; compare digests only at the same HEAD.

Fleet (overlays): 96.8% fn / 95.7% instr / 91.0% distinct-code matched. Unmatched: 11,550 instances / 577,080 ins (9,936 distinct classes).

Tail cross-check (Phase-25 close): 7,595 tail fns / 375,081 ins → 439 h_seq families ≥2, 72 substantial (nins≥80) / 30,992 ins.

Full frontier (all unmatched by h_seq): 2015 target families (≥2 members or a matched sibling) + 4513 singletons (Step-D residue). Substantial: 267 families / 95,614 templatable ins, 55 with a matched sibling (zero-crack). Substantial member classes: 677 PURE · 29 IMM · 6 STRUCT-excluded.
