# W01/W02 input handoff blocker The user selected **provide formal W01/W02 artifacts and continue**. The only new candidate found in the parent worktree was copied read-only into the pre-v1 contract snapshot from the repository history and verified against its recorded file hashes. It is not yet a formal release: - `SNAPSHOT.json` records `source_worktree: dirty` and a dirty-patch hash. - Its `snapshot_id`/`source` fields are not populated as a clean release ID. - `integration-manifest.json` still identifies runtime/RTP/worker integration artifacts as missing. - Repository-wide search found no `.proto`, generated stubs, or W02 Unary gRPC error/idempotency/activation-session contract. Required handoff before W02/W04 work can continue: 1. Clean W01 contract directory with release ID, source commit, file hashes, event-specific payload schemas, AI mode/parameter closure (GAP-08/GAP-09), OSS upload/session contract, and positive/negative fixtures. 2. W02 Proto package with exact service/method/message definitions, mTLS activation/session identity, error codes, idempotency and fencing semantics, plus generation/version instructions. The current bundle remains useful for local schema/routing tests only. It must not be treated as an authorization to invent a Proto or as G0/W04/P1 evidence.
