What problem does it solve? Setup stages in the A2MC calibration framework (a2mc-init, onboard-model, onboard-case) are easy to start but hard to finish: a stage abandoned mid-way leaves a clone that looks configured but silently misses fork guards, RAG milestone registrations, or target mappings, and the failure only surfaces much later. ## Core Features & Use Cases - Stage Detection: Determines which setup stage a clone is in (model onboarded, checkout configured, real use case present) using on-disk checks and the check_stage_ready.py tool. - Per-Stage Checklists: Provides the full definition-of-done contract for each of the three setup stages, with the executable gate named for every verifiable item. - Half-Built Clone Recovery: Audits an inherited, partially configured clone to find what is missing without restarting the stage. - Use Case: A new session inherits an A2MC clone that appears configured; run the stage audit to discover the RAG index was never committed and the milestone was never registered before any calibration work begins. ## Quick Start Ask the assistant to use the setup-discipline skill to determine which A2MC setup stage this clone is in and audit whether that stage is actually finished.
