What's new in Periscope.
## 2.60.2 — 2026-09-20 — Ferrite Z from datasheet, no graph_build abort
Beads with an MPN pull `impedance_ohm` from the datasheet or a quoted `N ohm @ freq` string. Missing Z after that is INSUFFICIENT, not a crash. Ohms are never written to `value_henries`. Leftover dependency validator no longer requires Z.
- [Fixed] `graph_build` loads DCR-only beads; leftover `ferrite bead requires impedance_ohm` removed.
- [Changed] Ferrite Z recovered from datasheet PDF / quoted value; extract-specs skill 1.15.0.
## 2.60.1 — 2026-09-20 — Ferrite bead without Z still loads
Ferrite beads that only have current/DCR validate. Missing `impedance_ohm` is not invented and does not crash `graph_build`. Other inductors still need `value_henries`.
