"""Plugin manifest schema sanity tests.
Four independent guarantees:
1. `schema/plugin.schema.json` is itself a well-formed JSON Schema
(Draft 2020-12) and accepts every in-tree `plugins/*/plugin.json`.
2. Each in-tree manifest's `id` matches its parent directory name —
the loader assumes this and silent drift would break plugin
discovery.
3. The `license` enum in the schema is a subset of the SPDX identifiers
listed in `CONTRIBUTING.md`'s "Plugin licensing" curated allowlist.
If you edit the allowlist in `CONTRIBUTING.md`, run pytest locally
and update the schema enum to match — these two files must stay in
sync because the same allowlist is referenced from both human-facing
docs and from CI manifest validation.
4. The schema accepts capability-pipelines.v1 manifest metadata so
native capability declarations stay first-class in tooling.
