Patch (unified git diff)

Below is a ready-to-apply unified git diff that implements the Ajv-based validation, per-API try/catch, logging/failure artifacts, adds the ajv devDependency, and a unit test. Save this to a file (e.g. generator-harden.patch) and apply with git apply generator-harden.patch (or copy the changes into your working tree and commit).

Notes & next steps

• The generator.ts file above is intentionally conservative and includes a TODO where you should call your existing single-API generator function (e.g. generateAPIFromDiscovery). If your repository already has that function name and path, import it at the top and remove the noop branch.
• If you prefer a smaller change (insert validation into your existing generator file rather than replace), you can copy the helper functions (validateDiscovery, snippetOf, formatAjvErrors, writeFailureArtifact) and wrap the per-API logic in a try/catch as shown.
• After applying the patch: run npm ci to install ajv and the test deps, then npm test (or your existing test command). The test provided is a lightweight, deterministic check demonstrating non-crash behavior on invalid JSON.
