# Phase 26 — h_seq family survey (T1)

> Generated by `tools/family_hseq.py` from the 134 overlay sigs + per-overlay src stubs. Ranked by TEMPLATABLE byte-weight (PURE+IMM members × nins × 4). The byte-gate is the arbiter.

**Fleet (overlays):** 82.5% fn / 63.6% instr / 40.5% distinct-code matched. Unmatched: 59,680 instances / 4,626,128 ins (34,021 distinct classes).

**Tail cross-check (Phase-25 close):** 42,139 tail fns / 2,299,092 ins → 601 h_seq families ≥2, **179 substantial (nins≥80) / 1,699,870 ins**.

**Full frontier (all unmatched by h_seq):** 2730 target families (≥2 members or a matched sibling) + 3553 singletons (Step-D residue). Substantial: **574 families / 3,015,589 templatable ins**, 29 with a matched sibling (zero-crack). Substantial member classes: 16,918 PURE · 39 IMM · 6 STRUCT-excluded.
