# 1.0.0-beta.21 Glagol Implementation Notes Scope: JSON Document Scalar Parsing Foundation. This Glagol-side slice prepares compiler/test/release-gate coverage for the source-authored `std.json` document scalar helpers: - `parse_string_document_result` - `parse_bool_document_result` - `parse_i32_document_result` - `parse_u32_document_result` - `parse_i64_document_result` - `parse_u64_document_result` - `parse_f64_document_result` - `parse_null_document_result` The focused beta21 test uses an explicit `std.json` import, checks/formats/tests the imported helpers, requires the helpers to exist in `lib/std/json.slo`, and asserts that no `std.json.parse_*_document_result` compiler-known calls or private `__glagol_json_*document*` runtime symbols are introduced. The JSON source-facade and promotion-gate inventories are updated to match the Slovo-side source/export/example work, which adds three JSON document scalar fixture tests and raises local and explicit `std.json` fixture output from 9 to 12 tests.
