symfony:api-platform-serialization

Api Platform Serialization (Symfony) Use when Designing or evolving API Platform contracts and operations. Aligning serialization, validation, and security behavior. Default workflow Define operation-level contract and payload boundaries. Implement resource/DTO/provider/processor changes with explicit mapping. Apply operation-specific validation and security constraints. Validate functional behavior across happy and negative paths. Guardrails Keep API contract explicit and version-aware. Avoid exposing internal entity fields implicitly. Prevent drift between docs and actual serialization. Progressive disclosure Use this file for execution posture and risk controls. Open references when deep implementation details are needed. Output contract API artifacts changed (resource/DTO/provider/processor). Contract/security decisions and rationale. Functional verification results. References reference.md docs/complexity-tiers.md
