# 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.
