Biped Slot Reference

Overview

Skyrim armor and clothing occupy biped slots numbered 30–61, stored as a bitmask in a record's BodyTemplate.FirstPersonFlags. This skill turns a slot — given as a number (52), a vanilla name (Body), or a community label (SOS, pelvis, a back/cape slot) — into the right housecarl_cross_plugin_query filter, so "find every armor on slot X" is one query instead of a guess. It is a reference-lookup skill with a short query procedure on top (the same look-it-up-never-guess discipline as mutagen-reference). The full slot↔bit↔value mapping lives in references/biped-slots.md.

The mapping is easy to get wrong by hand, which is why this skill exists: slot N is bit (N − 30) with value 2^(N − 30), and the field renders inconsistently (named slots as text, modder slots as raw numbers). A hand-guessed mask silently filters the wrong slot and looks like a clean answer.
