Triage Explainability Workbench

Recommendation

Do not restore the triage workbenches as separate products.

Merge them into the active triage list/detail loop, with lane controls at the list level and explainability tools in the artifact detail workspace.

Why

• QuietLaneWorkbenchComponent is really a list-state and queue-management concept.
• AiRecommendationWorkbenchComponent is a detail-side decision aid.
• ReasonCapsuleWorkbenchComponent is a provenance/explanation panel.
• TriageAuditBundlesComponent is a real supporting page, but it belongs beside triage, not as a separate workbench brand.

Primary Placement

• Menu group: Triage

Recommended submenu structure:

• Triage > Artifact Workspace
• Triage > Audit Bundles

Product Shape

Use one triage workspace with two layers:

1. List layer

• manages queues and lanes

2. Detail layer

• manages the current artifact/finding decision workspace

List-Layer Tabs

Inside Artifact Workspace, use tabs or segmented controls:

• Active
• Quiet Lane
• Needs Review

This is where the quiet-lane behavior belongs.

Detail-Layer Right Rail Or Secondary Tabs

In artifact detail, add contextual explainability surfaces:

• AI Recommendations
• Reason Capsule
• Provenance
• Decision History

These should be secondary tabs or a right-rail stack, not standalone routes.

Merge Map

Into list layer

• QuietLaneWorkbenchComponent

Into detail layer

• AiRecommendationWorkbenchComponent
• ReasonCapsuleWorkbenchComponent

Keep as sibling page

• TriageAuditBundlesComponent
  • keep as Triage > Audit Bundles
  • also deep-link from Evidence when useful

Placement For Single Actions And Stray Pages

AI suggestion apply / use VEX suggestion

• Keep inside artifact detail
• It is an action panel, not a page

Reason capsule

• Keep as expandable card or tab inside artifact detail
• It answers “why did this verdict happen?”, so it belongs next to the active decision

Provenance breadcrumb

• Keep in the detail right rail
• It is supporting context, not a route

Quiet lane recheck / extend TTL / promote

• Keep as list-row or bulk actions inside the Quiet Lane tab

Audit bundles

• Keep as a real page because it has its own list, download flow, and operator lifecycle
• Best home:
  • primary: Triage > Audit Bundles
  • secondary link: Evidence > Capsules / Exports

Suggested Route Sketch

• /triage/artifacts
• /triage/artifacts?lane=active
• /triage/artifacts?lane=quiet
• /triage/artifacts?lane=review
• /triage/artifacts/:artifactId
• /triage/artifacts/:artifactId?panel=ai
• /triage/artifacts/:artifactId?panel=reason
• /triage/artifacts/:artifactId?panel=provenance
• /triage/audit-bundles

What Not To Do

• Do not keep AI Recommendation Workbench or Reason Capsule Workbench as standalone brands.
• Do not turn every decision aid into its own route.
• Do not put quiet-lane logic on a separate page when it is fundamentally a list segmentation mode.

Final Call

Restore the capability, not the workbench branding. Triage should own one artifact workspace with lane tabs on the list view and explainability panels in the detail view, plus a sibling Audit Bundles page.
