Packages

enumeratio is a pnpm monorepo. The spine is the pure-SQL database; everything else is a consumer of it.

package	what it is
@enumeratio/data	The database as a package — the combinatorial catalog and whole schema as pure SQL (zero C). A pure-SQL Postgres extension; runs in any Postgres and in-browser via PGlite. Everything below reads through it.
@enumeratio/client	The TypeScript read-through client over the core: construct a collection, then enumerate, count, rank/unrank, project statistics, render representations, follow maps, value-address elements — lazily, against an in-browser (or node) PGlite.
@enumeratio/cli	A terminal enumerator — stream a collection's elements to stdout; a thin driver over the client, and home of the sage oracle tests.
@enumeratio/components	Every enumeratio web component (Lit): pure data→visual figures (*-glyph, *-figure, the three.js polytope views) plus client-backed enumeratio-* elements (expression, notation, figure) that resolve a resource straight from the db.

The explorer (@enumeratio/explorer, Vue + PrimeVue) is not a leaf package but the app that ties these together — it loads the DB and browses collections / handles / stats interactively, and is built and mounted inside this docs site.

Its guiding architecture, now core to the project: a collection page IS a composed SQL SELECT. The table's columns are the projection (SELECT), the column configurator edits that clause; filtering is WHERE; grading is GROUP BY GROUPING SETS (a plain table is (()), summary rows add (level), a TreeTable is the full ROLLUP); the footer's () group holds the overall aggregates; sorting is ORDER BY; rank vs ordinality are the canonical address vs the ordinal-measure position in the filtered result. Because the naive materialisation of that query is the definitional answer, it self-certifies the fast path. The full design is the query model.
