CALL NUMBER: ee_v2_layer.library_projection : skilltree_lib(3), map_layer(1) DEFINITION: project the certified KB as understand-X skilltree skills; call number = home class colon facets = the dependency web

Invoke this skill to understand library_projection down to its primitives. The RELATIVE ROOT below is the least-fixed-point closure of everything it bundles from — the full import cone, grouped by the lib each prim comes from. Projected from a prover-typed KB (MAP/SWI-Prolog consistency gate): every reference below resolves.

THE RELATIVE ROOT (the import cone, by lib)

from ee_v2_layer

• understand_skill (d1): a loadable unit of competence: X plus its relative root, consistency-typed
• relative_root (d2): the least-fixed-point closure of everything X bundles from, walked to prims or to consumers, tagged by origin lib

from map_layer

• certificate (d2): a replayable proof envelope over a construction: subject, payload, kappa, sha — monotone, never uncertifies

from skilltree_lib

• skilltree (d1): coordinate-addressed tree of skill dirs wired by Read-tool breadcrumbs, with validation and an FTS5 index
• skilltree_coordinate (d2): the hierarchical address of a node: root 0, child i = parent.i — the home class of the call number
• skilltree_rag (d2): build_index: one FTS5/BM25 table over every SKILL.md — retrieval returns ranked hits with shelf addresses

CONSUMERS (what needs this)

Projected from the the_toy_stack KB (57 concepts / 84 relations) — consistency-typed by MAP; the facet list after the colon IS the cross-lib dependency web.

(leaf — this is an actual skill.)
