Plan task P3.6 — pragmatic deviation. The plan called for stubs that internally route to /fp/landing/kanban + reshape; in practice the legacy fp_shopfloor_tablet OWL component (still registered, just unhooked from the menu) consumes a much richer payload (my_queue, active_wo, baths, bake_windows, gates, holds, pending_qcs, stations) than /fp/landing/kanban returns. Gutting tablet_overview to a stub would break that legacy component. Instead: add explicit DEPRECATED markers + INFO log lines on the three endpoints (tablet_overview, plant_overview, queue). Bodies stay intact so the legacy components keep working until Phase 5 cleanup retires both endpoints AND the legacy OWL components together. Note: /fp/shopfloor/plant_overview/move_card is NOT deprecated — the new Landing component still uses it for drag-and-drop. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
