v2.1.0

nexus-sdk

Added

• Added capability negotiated checkpoint waits, indexed dynamic field discovery, and exact linked table traversal while current object authority remains on the live RPC.
• Added one PTB helper that deposits a gas coin into several independent SUI address balances.
• Added exact inner state object references to validated snapshots so consumers can establish causal RPC visibility before evaluating dependent transactions.
• Added distinct archival replay endpoints for live event ingestors and exposed Move extracted protocol limits for consumers that must plan exact protocol windows.
• Added discovery of current Task and Execution objects through recent indexed gRPC activity, with concurrent scans, cursor resumption, and one metadata read per unique object.
• Added current Task dispatch offer reconstruction and exposed the existing occurrence settlement transaction builder.

Changed

• Move binding dependencies now use the published 0.3.0 crates with Sui 0.4.0 types.
• NexusError includes ObjectNotFound and InvalidTransactionOutput. Callers with exhaustive matches must handle both variants.
• EventPage includes a required source field that distinguishes replay from live events. Callers that construct or destructure pages must account for it.

Fixed

• Object reads now report a definitive absence as NexusError::ObjectNotFound instead of an untyped RPC error, so callers can tell a missing object from an unreachable node.
• TapActions::bind_agent_skill now transfers the newly created Agent to the signer after registering its first skill, preventing Sui from rejecting the PTB with an unused value that cannot be dropped.
• Dense event replay now delivers bounded pages and resumes interrupted ranges without skipping events.
• Sui transaction decoding now supports protocol 137 validity rules through Sui 0.4.0 dependencies and matching Move binding types.
• SDK builds with only types and signed_http now compile correctly, including toolkit consumers.

nexus-cli

Added

• Added nexus tap test, which resolves a TAP's MVR graph and runs Move unit tests with the selected Testnet or Mainnet Nexus bytecode in a local Sui VM.
• task create and task schedule now accept repeatable --authorization-binding <VERTEX>=<OBJECT_ID> values for Agent skills whose onchain Tools require workflow grants bound to a recipient.

Changed

• TAP scaffolds now use MVR dependencies and include an executable published bytecode unit test with a developer module extension.
• tap publish-skill now writes the canonical published DAG input commitment into its bind artifact.
• Generated Rust Tool projects now depend on SDK and toolkit 2.1.0.

nexus-toolkit

Changed

• Toolkit 2.1.0 now resolves SDK 2.1.0 through crates.io and shares its Sui 0.4.0 types.
