.base model (filters, formulas, properties, views; unknown keys kept in order; limits and invalid-value errors), evaluator with the D5 type rules, lazy if and boolean operators, memoised formulas with cycle errors, depth cap 200, string/number/object/list/date/link/file/regexp functions with lambdas (regex through notescraft-regex), and the map model (Web Mercator, tile ids, viewport tiles, grid clustering, coordinate and colour parsing, OSM attribution constants; Paris z10 is tile 518/352). Bases tasks 2, 5, 6 (Claude Sonnet) and 8 (MiniMax M3.1 Flash, OpenCode Zen free route). Verified: notescraft-bases suites all pass, clippy -D warnings, xtask layers and tree clean. Known gaps: toFixed rounds ties to even, list.unique is quadratic.
