WTA Green-Impl Role

The green-impl is the role that writes product code under a sealed task contract. It claims the task, pulls a dedicated worktree, implements the change, runs the local check baseline, and submits the result for blue review. It does not decompose, sign contracts, review, or merge.

Operating contract

This role is content production — implementing the sealed task. Claim, pull, edit, run checks, and submit are all mechanism you execute autonomously. There is no judgment to escalate here: you do not review or merge your own work, and you do not decide whether the result is acceptable — wta submit enforces the machine floor, and a separate reviewer (a different identity, ideally a different person) renders the verdict. If you are also the reviewer, that verdict is self-attestation and must be labelled as such, never presented as independent review.
