Summary

• Route the authoritative Minecraft#setScreen(Screen) TAIL boundary through a shared client screen lifecycle adapter.
• Make non-chat screen opens terminal SCREEN_OPEN ownership boundaries, including macro stop, transient inventory/task/rotation/input cleanup, and settings-save precondition reconciliation.
• Preserve only the exact command-armed chat close exemption and add focused inventory, pause, settings, lifecycle, and idempotence coverage.
• Record exact AUDIT-014 base, parent P0-13/P0-15 failures, upstream anchors, file hashes, and verification evidence.

Root cause

The current-master screen observer did not receive the real setScreen mutation boundary as a terminal event. Non-chat transitions remained SCREEN_CHANGED, whose macro fanout is state-preserving, leaving SCREEN_OPEN stale after real inventory and Escape flows.

Parent-owned real-client P0-13/P0-15 rerun remains the distinct post-publication validation boundary described in AUDIT-014.
