docs(fusion_plating_shopfloor): brainstorm spec for tablet redesign
Multi-section design covering:
- 3 OWL client actions: fp_shopfloor_landing (replaces fp_shopfloor_tablet
+ folds in fp_plant_overview), fp_job_workspace (NEW full-screen WO
surface), fp_manager_dashboard (refactored — 4 sibling tabs incl.
Workflow Funnel, Approval Inbox, At-Risk).
- 5 shared OWL services: WorkflowChip, GateViz, SignaturePad,
HoldComposer, KanbanCard — reused across all three client actions to
enforce one-widget-one-place and prevent terminology drift.
- Backend additions: 8 new RPC endpoints, blocker_kind/reason computes
on fp.job.step, display_wo_name + late_risk_ratio + active_step_id on
fp.job, bottleneck_score on fp.work.centre, auto-pause cron (fixes
411h ghost timer), ACL lift for operator group per "techs wear
multiple hats" rule.
- Terminology pass: WO # 00001 (display only, sequence rename deferred),
Shop Floor / Up Next / Embrittlement Bakes / etc.
- 5-phase deploy sequence, each phase independently shippable.
- Out of scope (deferred to v2): cost roll-up, cycle time, per-tech
throughput, system-wide sequence rename.
