Done Retirement

Pipeline retirement processor for the Gastown chipset. When a polecat finishes its work, the done retirement pipeline takes over -- it validates the work, commits and pushes the branch, creates a merge request, notifies the convoy and mayor, cleans up the workspace, and terminates the agent. In hardware terms, done retirement is the instruction retirement unit -- it takes completed instructions from the execution unit (polecat), writes results to the register file (shared repository), updates the reorder buffer (merge queue), and frees execution resources (workspace and agent slot).

Activation Triggers

This skill activates when:

• A polecat has completed execution and is ready to retire its work
• An agent's hook status transitions to completed
• A work item's status transitions to done
• A convoy needs to track individual bead completion

Core Capabilities

The 7-Stage Retirement Pipeline

Every retirement flows through seven stages in strict order. The pipeline has an irreversibility boundary at Stage 3 (Push). Before push, the retirement can be aborted and the bead returned to in_progress. After push, the process is irreversible -- the branch is in the shared repository and the workspace will be destroyed.
