feat(antd-java): gRPC external-signer prepare/finalize parity with REST - #172
Merged

Conversation
Adds 7 new methods on `GrpcAntdClient` mirroring the existing REST `AntdClient` external-signer surface: * `prepareUpload(path, visibility)` / `prepareUpload(path)` / `prepareUploadPublic(path)` * `prepareDataUpload(data, visibility)` / `prepareDataUpload(data)` * `finalizeUpload(uploadId, txHashes)` (wave-batch) * `finalizeMerkleUpload(uploadId, winnerPoolHash, storeDataMap)` plus arity-2 overload defaulting `storeDataMap` to false * `prepareChunkUpload(data)` * `finalizeChunkUpload(uploadId, txHashes) -> String` The async surface (`AsyncAntdClient`) is REST-only — there is no async gRPC counterpart in this SDK — so the async paths are unchanged. Async gRPC support is out of scope here. Wallet stubs aren't present on `GrpcAntdClient`; the wallet-over-gRPC surface is a separate ticket. Proto/build: * Gradle's protobuf plugin auto-generates `Upload.*`, `Common.PaymentEntry`, and the new `Chunks.PrepareChunk*` / `Chunks.FinalizeChunk*` messages from `../antd/proto/`. No regen recipe to invoke. * `GrpcAntdClient` gains an `UploadServiceGrpc.UploadServiceBlockingStub uploadStub` field, constructed alongside the others. * Helpers `prepareResponseToResult` / `finalizeResponseToResult` translate proto into model records, populating merkle-only fields (`depth`, `poolCommitments`, `merklePaymentTimestamp`) only when `payment_type == "merkle"`. Tests (`GrpcAntdClientTest`): * `MockChunkService` gains `prepareChunk` (new + already-stored short-circuit) and `finalizeChunk` (echoes `upload_id` into address). * New `MockUploadService` covers wave-batch / merkle / visibility round-trip via `upload_id` encoding / `store_data_map` true|false. * 12 new tests parallel to the antd-rust / antd-go / antd-py suites. Gates passed on dev2: * `./gradlew compileJava` clean * `./gradlew test --tests GrpcAntdClientTest` — 31/31 (the 19 existing plus 12 new) * `./gradlew build` — full project including examples passes Depends on the antd-side daemon PR landing first.

Closes the gRPC parity gap with REST: external-signer (UploadService + chunks PrepareChunk/FinalizeChunk) and WalletService are now reachable over gRPC, plus stream-download stubs return honest UNIMPLEMENTED/501 instead of pretending. All 11 gRPC-capable SDKs follow with matching fan-out. ## Additive (antd daemon) - gRPC UploadService + chunks prepare/finalize — external-signer two-phase upload + single-chunk publish over gRPC, mirroring REST 1:1 (#140) - gRPC WalletService — GetAddress / GetBalance / Approve, parity with REST /v1/wallet/* (#154) - /v1/data/prepare now honors visibility for public DataMap chunk bundling via data_prepare_upload_with_visibility (#138) ## Fixes (antd daemon) - Stream-download stubs (DataServiceStub.StreamDownload, REST /v1/data/stream/*) now return UNIMPLEMENTED / 501 honestly rather than empty success (#155) ## SDK fan-out — external-signer (gRPC prepare/finalize) All 11 gRPC-capable SDKs replace their stub raises with real gRPC calls to the new UploadService + ChunkService PrepareChunk/FinalizeChunk RPCs: - antd-rust (#169), antd-go (#170), antd-py (#171), antd-java (#172), antd-kotlin (#173), antd-csharp (#174), antd-ruby (#175), antd-dart (#176), antd-swift (#177), antd-cpp (#178), antd-elixir (#179) ## SDK fan-out — WalletService Same 11 SDKs gain walletAddress / walletBalance / walletApprove over gRPC: - antd-rust (#180), antd-go (#181), antd-py (#182), antd-java (#183), antd-kotlin (#184), antd-csharp (#185), antd-ruby (#186), antd-dart (#187), antd-swift (#188), antd-cpp (#189), antd-elixir (#190) ## SDK examples + build fixes - antd-ruby: payForQuotes tuple args as Hash for eth-0.5.13 compatibility (#131) - antd-go + ant-dev: add 03-chunks + 06-private-data examples; renumber 03-files to 04-files (#132) - antd-java + antd-cpp: close async client surface gaps (#133) - ant-dev: pull antd[rest,grpc] extras so 08_grpc example runs out of the box (#134) - antd-js + antd-py + antd-go READMEs: surface external-signer methods + 07 example (#135) - antd-elixir: 07_external_signer example via cast shell-out (#136) - antd-swift: 07_external_signer example + fix FinalizeUploadDTO optional address (#137) - antd-php: empty tx_hashes serializes as JSON object on finalize (#139) ## FFI - ant-ffi refresh against current ant-core API + Swift xcframework build pipeline (#150) - Android AAR build pipeline (#156) ## Infra - CI: auto-tag Go submodules on umbrella release tag push (#129) - Deploy: publish multi-arch withautonomi/antd image from ant-sdk release (#130) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
