An API Delivery Review with NDJSON, OpenAPI, and SemVer

Validate the record boundary first

JSON Lines is useful for logs, training sets, and bulk transfer because every line is an independent JSON value. A sound quality gate parses each record, reports the exact line, and never silently discards malformed data. Otherwise downstream counts become unreliable.

JSON Pointer locates nested values without copying a large document. Correct handling of RFC 6901 escapes and an explicit first-unreachable segment make debugging practical; a resolved value still needs schema and domain validation.

• Compare record counts before and after conversion.
• Surface malformed lines instead of skipping them.
• Verify pointer results against the intended schema.

Turn OpenAPI into a reviewable inventory

Method, path, operationId, tags, deprecation, and security declarations form a useful delivery inventory when shown together. Missing names and unexpectedly anonymous operations become much easier to spot.

A security field in a specification does not prove runtime authorization. Use the inventory to prioritize source review and authorized testing; it deliberately makes no request to a live server.

• Check operationId uniqueness separately.
• Document a removal plan for deprecated routes.
• Map declared schemes to actual middleware.

Separate SemVer precedence from compatibility

SemVer rules place 2.0.0-beta.11 after beta.2 but before 2.0.0, while build metadata does not change precedence. That orders releases; it does not prove behavioral compatibility.

Combine the sorted version, changelog, contract tests, and consumer expectations. Browser-only review protects sensitive specifications during preparation, while final approval remains an engineering decision.
