From d19b0f137fb257786ec1341146105e893b5407de Mon Sep 17 00:00:00 2001 From: Antonio Ramirez Date: Sun, 31 May 2026 06:09:45 +0200 Subject: [PATCH] feat(scaffold): x-altair-idempotency round-trip activation (#175) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Activates the x-altair-idempotency OpenAPI extension end-to-end now that the corresponding idempotency: spec block landed in #174: Forward (spec:emit-openapi) - OpenApiEmitter writes x-altair-idempotency: { ttl, scope } when the spec carries an idempotency: block. - `mode` is intentionally excluded — it's a server-side enforcement concern (optional vs required header), not a wire contract. Reverse (openapi:import) - OperationMapper reads x-altair-idempotency and emits an equivalent idempotency: block on the imported spec. - ttl and scope round-trip verbatim; mode defaults to 'optional' on the reverse path since the source did not carry it. Round-trip gate (openapi:roundtrip) - OpenApiRoundtripRunner adds x-altair-idempotency to the compared extension set. A regression that drops the block would now produce a `kind: extension_drift` entry in the receipt and fail openapi:roundtrip --check. Docs - docs/openapi/extensions.md moves x-altair-idempotency out of the "carried through" row into the "round-trips" row. - docs/openapi/roundtrip.md adds x-altair-idempotency to the compared-set listing and removes it from the reserved-key limitation footnote. Tests (+5) - OpenApiIdempotencyRoundtripTest covers the forward emit, the reverse import (including the mode-defaults-to-optional rule), and the round-trip pipeline producing a clean receipt. Existing snapshot tests stay byte-for-byte identical because the createUser fixture doesn't carry an idempotency block. Out of scope (per #171) - Package doc + benchmark variant — #176. Part of #171.
