# 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.
