Native (non-ESPN) families — vendored from sdv-py

Source of truth: sportsdataverse-py's endpoint YAML for each family at the pinned commit (tools/codegen/vendor.yaml → families:), with its returns schemas under tools/codegen/schemas/native/<family>/. A family's YAML names the host, every endpoint's path and params, its parser and its returns schema. vendor.yaml records per family which sdv-py parsers the JS parsers are faithful ports of (schema_compatible), so a returns table is attached only when it describes what the JS parser returns (fail-closed: no table beats a wrong one). A family with tools/codegen/overlay/<family>.yaml gets JS-only endpoints and patches merged on top.

Generator step: generate.mjs loads each tools/codegen/endpoints/<family>.yaml, applies sdv-py's name_pattern / qualifier naming, and renders src/generated/flat/<family>.ts (a written module, one export const per endpoint, typed Wrapper / SectionedWrapper), src/generated/params/<family>.ts, and — for every endpoint the parser-parity harness verified on a real sdv-py capture (test/fixtures/py/parity_coverage.json) — a row interface in src/generated/rows/<family>.ts. The docs get a "Native API — family" section on the league page (docs/docs/<league>/reference/native.md) or a standalone provider page (docs/docs/reference/<namespace>.md), with a returns table and the row type per endpoint.

Where output lands: src/generated/flat/, src/generated/rows/, src/generated/params/, the league native.md pages and docs/docs/reference/<provider>.md.

CI drift gate: npm run vendor:check, npm run codegen:check, test/flat-contract.test.js, the parser-parity harness (test/parsers/parity.test.js) and test/types/agreement.test.js (every parsed value on the committed captures against its generated row type).

How to change it: endpoints change in sdv-py, then re-vendor. A JS-only endpoint or a different parser binding goes in the family's overlay. A parser port that diverges from sdv-py's drops the returns table through schema_incompatible in vendor.yaml rather than shipping a wrong one.
