Single board topology. Build phases, terminal columns, column labels, manual phase-entry checkpoints, and the stage-to-board projection now share one vocabulary. The move RPC, board UI, and tests consume it rather than carrying parallel literal lists.
Reopened completion state. A new card comment or direct worker-thread turn on a completed card immediately returns it to In progress while preserving the state-file-owned checkpoint until the worker advances it. This removes the stale “Saved locally” publication presentation as soon as new work begins.
Timeline consistency. The current checkpoint is disabled for every active workflow stage, not only a completed card's retained Audit record.
