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 217 binary sigs + per-binary src stubs. Ranked by TEMPLATABLE byte-weight (PURE+IMM members × nins × 4). The byte-gate is the arbiter.

Scope (217 binaries): 141 location overlays + 75 md_ modules + the resident · MAIN IS EXCLUDED* · generated at HEAD 5bc4a5c0ab · 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): 100.0% fn / 100.0% instr / 100.0% distinct-code matched. Unmatched: 0 instances / 0 ins (0 distinct classes).

Tail cross-check (Phase-25 close): 0 tail fns / 0 ins → 0 h_seq families ≥2, 0 substantial (nins≥80) / 0 ins.

Full frontier (all unmatched by h_seq): 0 target families (≥2 members or a matched sibling) + 0 singletons (Step-D residue). Substantial: 0 families / 0 templatable ins, 0 with a matched sibling (zero-crack). Substantial member classes: 0 PURE · 0 IMM · 0 STRUCT-excluded.
