Drew T bcc3130eb4 feat(phase-30 S49): the A-prop word-diff card + aprop_wave — 56 banked from the >=16 head (§170)
- NEW family_cousins.py --aprop-cards + tools/wave/aprop_wave.js: lane A (1,700 open fns /
  76,419 ins) had NO card type — cousin diffs are empty for h_seq-identical members, so the card
  is a positional WORD diff vs the matched sibling, grouped BY FAMILY (one agent, N drafts).
  Head cards: 13 families / 433 members, median TWO differing words each.
- calibration 9 batches / 108 members: 98 agent-MATCH (91%, best of any wave) -> 56 BANKED (57%),
  ~80k tok/banked fn vs 157k (cousin card) vs 400k+ (crack wave). R22 213/213 BYTE-IDENTICAL.
- HONEST GAP (R14): 91% agent -> 57% gate is the worst conversion measured; 14 groups banked 0.
  Hypothesis TESTABLE not proven — family batching concentrates members per destination TU, the
  §169 collision. Re-gate unbanked ONE PER TU before scaling the remaining 320.
- >=16 head diagnosed: 3 of 4 blockers are plumbing — the --band substantial default hid 5 of 13
  families from every prior sweep; one missing file-scope extern (D_801ED98C) gates 56 PURE
  members; dedup_extend is macro-only. Only func_8017C294 is a genuine crack.
- fleet 96.56% fn / 95.2% instr / 89.9% distinct; stubs 12,535 -> 12,468; dedup 2,043/0.
- cookbook §170.

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:1843 · 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 / 91.1% distinct-code matched. Unmatched: 11,501 instances / 573,821 ins (9,892 distinct classes).

Tail cross-check (Phase-25 close): 7,541 tail fns / 372,807 ins → 440 h_seq families ≥2, 72 substantial (nins≥80) / 30,992 ins.

Full frontier (all unmatched by h_seq): 2014 target families (≥2 members or a matched sibling) + 4504 singletons (Step-D residue). Substantial: 266 families / 94,856 templatable ins, 59 with a matched sibling (zero-crack). Substantial member classes: 671 PURE · 29 IMM · 6 STRUCT-excluded.
