Branch D — Mock Data Generation Result

Output: …/ui-preview/mow/unified-canvas/v1/mock-data.json (18,963 bytes, JSON-valid). Source: Component 3 (CanvasNode / CanvasContext) of the spec. No user input requested.

Coverage (all required dimensions present)

• Tiers T6→T1 — each with a CanvasContext (breadcrumb deepening T6→T1) + CanvasNode[].
• Normal state — default active_tier = T3 (Chuyên môn → Nhiệm vụ/Workflow), template view.
• Proposal mode state — states.proposal with sample_proposals[] (one edit, one add) matching dot_mow_design_propose_change shape (target_node_id, change_type, proposed_data, reason, iu_ref, status=pending).
• Instance state — node_instance_overrides exercising the full 9-state enum (created/assigned/in_progress/waiting_for_approval/completed/overdue) + SLA traffic lights (green/yellow/red/blue/orange) + assignee avatars + progress_ratio.
• Large / governance-alert state — freeze active, 1/2 approvals (Đ32/37), and a large_scale_demo (47 children, +44 overflow) for scale handling.
• Node/card fields — full canonical contract: id, code, title, tier, parent_id, order_index, status, traffic_light, child_count, child_preview (≤3), automation_level, workflow_ref, task_type_ref, iu_ref, proposal_count, permission_actions, instance_data.
• Traffic-light examples — green/yellow/red/gray on T2 nodes; legend embedded.
• permission_actions examples — [view], [view,propose], [view,propose,admin].
• No production secrets — all ids are fabricated UUID-shaped strings; content is illustrative HR workflow.

Caveat (logged, not silent)

Mock is illustrative, not backend-verified. The CanvasNode→PG column mapping (reuse-first, no new tables) is deferred to the live PG survey — see mock-data-contract.md and the master pack Branch H.
