• Improved paragraph margins
• Styled horizontal rules
• Enhanced list formatting
• Blockquote design improvements

This ensures clean typography and consistent formatting for long-form content.

• Resolved session timing issues related to prerendering and InteractiveServer lifecycle.
• Improved ManufacturerOwner, ManufacturerAdmin, and ManufacturerAuditor separation.
• Ensured consistent access enforcement for tenant, tier, and role combinations.
• Standardized dependency injection using service interfaces for improved reliability.

🏭 Manufacturer Enhancements

• Improved tenant-aware session handling.
• Stabilized Manufacturer-specific dashboards and settings pages.
• Improved security around user management and lifecycle access.

🛡 Auditor Governance Dashboard

• Dedicated Auditor dashboard with lifecycle oversight metrics.

This release significantly improves platform stability, governance transparency, and role clarity across Manufacturer environments.

Version: v2.1.0

Product Update: Manufacturer Navigation + User Invitations + Transfer Quantity groundwork

• User invitations fixed (Manufacturer tenant): Resolved EF Core query translation error caused by calling a custom role-normalization method inside LINQ-to-Entities. Roles are now matched safely after loading role records, allowing invites to complete successfully.
• Invite UX improved: Added/verified busy state behavior and UI messaging so users get immediate feedback while invites are processing, and the table updates after completion.
• Transfers: Quantity groundwork: Added Quantity to OwnershipTransfer (default 1) and prepared payload support so ledger health events can include the number of units transferred.
• Navigation roles fixed: Implemented robust role normalization in UserSessionDto so values like ManufacturerAuditor correctly map to Auditor, and spacing/format variants (e.g. “Lifecycle Manager”) are handled consistently. This makes the role-based navigation matrix functional.
• Verification: Confirmed Manufacturer Auditor can be created and sign in, and role label displays correctly on the dashboard. Navigation visibility now follows the configured role flags.

🚀 Manufacturer & Auditor Release: Lifecycle Dashboards + Recycle Oversight

Today we expanded the Manufacturer lifecycle experience and introduced a read-only Auditor dashboard view. We focused on making lifecycle and recycling activity easier to monitor without querying the ledger (SQL remains the UI source of truth; ledger is immutable audit proof).

🧭 Lifecycle Manager (Manufacturer)

• Added a new Recent Activity panel to show the latest lifecycle actions (top rows) with a View all link into Governance.
• Aligned the UI direction so Manufacturers review partner lifecycle events via /manufacturer/governance.
• Confirmed recycle metrics are stored in SQL (not ledger parsing) and can be displayed directly.

♻️ Recycling Metrics Visibility

• Verified recycling inputs are captured per event (Input weight, Recovered weight, Recovery %, Method, Energy recovery %, Hazardous handled, Material breakdown).
• Recycle metrics are stored as JSON in SQL (e.g. LifecycleEventRecycleMetric.MetricsJson and/or LifecycleEvent.RecycleMetricsJson).
• Implemented parsing that supports both JSON shapes:
  • Top-level fields (e.g. inputWeightKg), and
  • Nested payloads (e.g. { recycle: { inputWeightKg: ... } }).
• Recycle Oversight now loads using SQL-first lookup (table metrics preferred; event JSON as fallback).

🕵️ Auditor Dashboard (Read-only)

• Created an Auditor Dashboard concept for read-only oversight: integrity, compliance and audit readiness.
• Added KPI cards: Lifecycle events (30d), End-of-life events (30d), Pending reviews, Latest event.
• Added Attention Required table (Pending/Rejected/Corrected) with a direct navigation to Governance.
• Added Recycle Oversight table showing latest recycle metrics per event (Input/Recovered/Recovery%/Hazardous).
• Added a Search box that filters both Attention Required + Recycle Oversight tables.

✅ Governance & Review Flow Confirmed

• Partner submits lifecycle events (including recycle metrics).
• Manufacturer reviews and approves/rejects via Governance workflow.
• Approved events are visible in product event details and in the product ledger timeline.

Note: UI queries use SQL tables for performance and correctness. Ledger is retained as immutable audit evidence.
