Merge Risk: 🔵 Low · up to Invalid route status declarations can produce contract artifacts that cannot be parsed. Validate statuses during artifact creation before merging, or accept this bounded risk. Pre-merge checks |

- Line 442: createContractGraphSnapshot에서 응답 스키마를 스냅샷으로 변환한 뒤 successStatus에 기존
상태 검증 규칙을 적용하고, 유효하지 않은 상태는 스냅샷에 기록되지 않도록 하세요. successStatus가 999인 경우와 응답 스키마가
있는 경로에 204 또는 205를 지정한 경우도 거부되도록 하며, createContractGraphV1에서 이 생성 경로를 사용할 때도 동일한
검증이 적용되게 하세요.

Closes #3217.
Both ContractGraph artifact formats now preserve the effective REST success status, so an HTTP 201→202 change produces artifact drift and the breaking diagnostic
contract-success-status-changed. Historical v1 artifacts may omit the field: parsing and diff consistently infer 200 with a response schema and 204 without one. Persisted statuses must be valid 2xx integers; 204/205 cannot accompany a body schema.Includes a
protocols-corepatch changeset. Runtime response selection, status decorator APIs, OpenAPI emission, and Problem status behavior remain unchanged.Validation
Elevated profile: public snapshot/V1 types and persisted contract semantics reach CLI and generated-contract consumers.
Generated-contract evidence
The selected
rest-spa-contractssmoke passed local packaging, snapshot generation, guarded live-controller diff, OpenAPI/client drift checks, client typecheck, and strict rejection canaries. Generated SaaS/SPA install-immediate contract verification also passed.The static companion reports
needs-checks; its architecture/public API/repository selections are reconciled with the passing gates above, and its generic generated-app selection is covered by the focused REST smoke. Both independent reviews accepted this scope. The initial broad ecosystem smoke was failed/stopped after four unchanged SaaS billing/usage demo tests exceeded their 30-second limits. A separate unchanged DI-generation invocation took 36.02 seconds; this demonstrates a timeout-budget risk, not the exact cause of the original failures. The broad matrix is not claimed as passing.Head:

c18f79a98336888c44ca6909ff1090c8f06f8b40Historical artifacts cannot recover explicit statuses discarded by the previous serializer; the documented schema-based default is the compatibility boundary.
Base drift
Current base:

The nullable HTTP response fix preserves the schema-based 200 default and explicit 201/202; unrelated metrics grouping does not reach this contract. Candidate HTTP status/nullable parity tests passed 126 cases, and status serialization/diff tests passed 18 cases. Independent drift code review and integration verification passed. No rebase was needed.Generated API documentation now includes both public route status fields.
pnpm docs:api:checkpasses, and the normal pre-push hook again passed full tests and guarded typecheck. The reported serializer-validation concern was withdrawn after confirming that diagnostic-bearing graph snapshots intentionally retain invalid declarations; executable consumers validate before use.Resumed integration verification
#3495 was resolved on trunk by #3502. Current base is
a6ce270e5cc1c766891baf860b0a581eb3b20ba9; additional registry, QStash and admin literal-null changes were independently reviewed as non-interacting with the persisted success-status contract. The existing head is unchanged. The PR was reopened to run CI against the refreshed merge candidate: 38134265985. Prior failed runs cover the previous base and remain recorded above; current-base CI is pending.Later base
