Validate at run creation and between pipeline stages.\n\n## Current State\ninputs.json is untyped. No schema validation.\n\n## Target State\nProcess definitions include input/output JSON schemas. Validation at run:create time. Validation between pipeline stages. Type-safe process composition.\n\n## Dependencies\n- None\n\n## Key Files\n| Component | Path |\n|-----------|------|\n| Runtime | `packages/sdk/src/runtime/` |\n| Storage | `packages/sdk/src/storage/` |\n| Process definitions | `.a5c/processes/` |\n\n## Recommendation\nM0 (Quick Wins) implementation. Add inputSchema/outputSchema to process metadata. Validate inputs.json against schema at run creation.\n",
