Verification: Backend Services for Item Image Upload

Bidirectional traceability between requirements and acceptance criteria from the goal. Status column tracks verification progress during implementation.

Note: AC numbers correspond to the goal.md Success Criteria numbering and are intentionally non-sequential within sections to preserve traceability.

Traceability Matrix

Presigned Credential Generation

AC	Req	Acceptance Criterion	Verification Method	Status
1	REQ-BE-002	AssetKeyGeneratorTest — key format <tenantId>/images/<uuid>.<ext>, tenant prefix, UUID uniqueness, extension mapping	Unit test	Pending
2	REQ-BE-003, REQ-BE-007, REQ-BE-008	CdnUrlResolverTest — URL construction, pattern validation (rejects non-CDN), tenant isolation (rejects cross-tenant), null handling	Unit test	Pending
3	REQ-BE-001, REQ-BE-005, REQ-BE-006	S3AssetServiceTest — presigned POST form with all 7 policy conditions, HEAD verification, metadata validation	Integration test (MockAWS)	Pending
6	REQ-BE-004, REQ-BE-013, REQ-BE-014, REQ-BE-015, REQ-BE-016	ImageUploadEndpointTest — auth, presigned generation, response includes uploadUrl, formFields, objectKey, cdnUrl	Integration test (Harness + MockAWS)	Pending

Entity Persistence and Validation

AC	Req	Acceptance Criterion	Verification Method	Status
7	REQ-BE-007, REQ-BE-008, REQ-BE-009	Entity update with CDN-pattern imageUrl succeeds after HEAD verification	Integration test	Pending
8	REQ-BE-007	Entity update with non-CDN imageUrl rejected (400)	Integration test	Pending
9	REQ-BE-010	Entity update with imageUrl: null clears the image field	Integration test	Pending
10	REQ-BE-011	Entity update with unchanged non-CDN imageUrl succeeds without validation (TD-15)	Integration test	Pending

Infrastructure

AC	Req	Acceptance Criterion	Verification Method	Status
11	REQ-BE-017, REQ-BE-018	pre-install.cfn.yml includes IAM policies for image asset bucket and presigning role	Code review	Pending
16	REQ-BE-019	Helm configmap includes all required image infrastructure values; Helm lint passes	Code review + Helm lint	Pending

Refactoring and Regression

AC	Req	Acceptance Criterion	Verification Method	Status
4	REQ-BE-022	Existing CsvS3DirectAccessTest and S3BucketAccessTest pass after refactoring	Unit test (existing)	Pending
13	REQ-BE-021, REQ-BE-022	No regressions in existing CSV upload functionality	Unit test (existing)	Pending

Build and Coverage

AC	Req	Acceptance Criterion	Verification Method	Status
5	REQ-BE-NFR-004	common-module builds successfully (make clean build)	Build output	Pending
