Mission Run Overview
Mission Run: Plan Concern Vocabulary and WP Traceability
Introduce implementation concern (IC-##) vocabulary at the plan phase and add concern-to-WP traceability to the task manifest, eliminating plan/task pseudo-WP drift.
The plan phase currently uses work-package-like language (Parallel Work Analysis, Work Distribution, Agent Assignments) that causes agents and reviewers to treat plan slices as pseudo-WPs. When real WP## units are generated by the tasks phase, they diverge in wording from plan slices with no machine-readable link explaining the translation. This mission introduces a formal implementation concern vocabulary at the plan phase and a plan_concern_refs field in the WP manifest so that every WP can cite which concern(s) it covers, making the plan-to-tasks translation explicit and traceable.
