+# 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.
+
+## Detailed UX And Sprint
+
+- Detailed UX dossier: `../triage-explainability-workspace/README.md`
+- Implementation sprint: `../../../implplan/SPRINT_20260307_027_FE_triage_explainability_workspace.md`
+
+## Corroborating Inputs
+
+- `docs/UI_GUIDE.md`
+- `docs/ui-analysis/03_TRIAGE_POLICY_OPS_SCREENS.md`
+- `docs/ui-analysis/05_ROUTE_SUMMARY_AND_OBSERVATIONS.md`
+- `src/Web/StellaOps.Web/src/app/routes/security-risk.routes.ts`
+- `src/Web/StellaOps.Web/src/app/features/triage/triage-artifacts.component.ts`
+- `src/Web/StellaOps.Web/src/app/features/triage/triage-workspace.component.ts`
+- `src/Web/StellaOps.Web/src/app/features/triage/triage-audit-bundles.component.ts`
+
+## 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.
