[funderbrker]

Tractor SDK

This PR provides basic SDK functionality for interacting with Tractor. It also expands current functionality of pipeline.

Features

• Easy composition of sequences of actions
• Common reward actions
• Standardized handling of byte-level data
• Tooling to assist operators in simulating Blueprints

What this is not

• A standardized set of Blueprints that will be offered.

Status

• Core SDK design in place. Compiles and runs. Test reverts contract side.
• Minor whitepaper corrections Pipeline#9 issue replicated here. Seeing an extra 32 bytes in clipboard data constructed through SDK. Consensus is that these bytes are expected and whitepaper should be updated to represent them.

Todo

• Refine SDK design. Some structure can be slightly shuffled to improve usability.
• Implement standard Blueprint and sub-blueprints
• Implement full suite of tests that cover both Tractor SDK and Contracts. Deprecate existing js Tractor tests.
• UI design & implementation (out of scope for this PR)
