+# Evidence Thread and Persona Workspaces Route Reconnection
+
+## Module
+Web
+
+## Status
+IMPLEMENTED
+
+## Sprint
+SPRINT_20260308_021_FE_unreachable_evidence_thread_and_persona_workspaces_routes
+
+## Description
+Reconnected the disconnected evidence-thread and persona-workspace route families under the canonical `/evidence` route shell. Evidence threads and auditor/developer workspaces are now reachable through Evidence-owned URLs, acting as evidence lenses rather than a parallel product shell.
+
+## Canonical URL Contract
+- `/evidence/threads` - Evidence thread list
+- `/evidence/threads/:artifactDigest` - Evidence thread detail
+- `/evidence/workspaces/auditor/:artifactDigest` - Auditor workspace (compliance lens)
+- `/evidence/workspaces/developer/:artifactDigest` - Developer workspace (findings lens)
+
+## Implementation Details
+- **Route file**: `src/Web/StellaOps.Web/src/app/routes/evidence.routes.ts`
+  - Added `loadChildren` entries for threads, auditor workspace, and developer workspace
+- **Feature routes updated**:
+  - `src/Web/StellaOps.Web/src/app/features/evidence-thread/evidence-thread.routes.ts` - Added breadcrumb data
+  - `src/Web/StellaOps.Web/src/app/features/workspaces/auditor/auditor-workspace.routes.ts` - Added breadcrumb, updated sprint ref
+  - `src/Web/StellaOps.Web/src/app/features/workspaces/developer/developer-workspace.routes.ts` - Added breadcrumb, updated sprint ref
+- **Tests**: `src/Web/StellaOps.Web/src/app/routes/evidence.routes.spec.ts`
+
+## Key Decisions
+- No separate top-level persona menu introduced
+- All persona workspaces remain Evidence-owned drill-ins under `/evidence/workspaces/`
+- Route titles and breadcrumbs align with the Evidence shell pattern

+# Sprint 20260308-021 - FE Unreachable Evidence Thread And Persona Workspaces Routes
+
+## Topic & Scope
+- Reconnect the disconnected evidence-centric route files that still fit the current Evidence shell.
+- Mount `EVIDENCE_THREAD_ROUTES` and the auditor or developer workspace routes under the canonical `/evidence` route family.
+- Keep these routes inside the Evidence product; do not create separate top-level persona navigation.
+- Working directory: `src/Web/StellaOps.Web`.
+- Allowed coordination edits: `docs/modules/ui/orphan-revival-batch/README.md`, `docs/modules/ui/TASKS.md`, `docs/modules/ui/implementation_plan.md`, `docs/features/checked/web/`, `src/Web/StellaOps.Web/src/app/routes/evidence.routes.ts`, `src/Web/StellaOps.Web/src/app/features/evidence-thread/`, `src/Web/StellaOps.Web/src/app/features/workspaces/auditor/`, `src/Web/StellaOps.Web/src/app/features/workspaces/developer/`, and the mounted Evidence host components that expose entry points.
+- Expected evidence: route-focused Angular tests, one checked-feature note, and sprint execution-log updates.
+
+## Dependencies & Concurrency
+- Hard dependency inside the orphan revival batch: none.
+- External prerequisite already satisfied: the current `/evidence` shell is already canonical and mounted.
+- Safe parallelism:
+  - Can run in parallel with sprints `013` through `020`.
+  - Can run in parallel with sprints `022` and `023` because the route-parent ownership does not overlap.
+
+## Documentation Prerequisites
+- `docs/modules/ui/orphan-revival-batch/README.md`
+- `src/Web/StellaOps.Web/AGENTS.md`
+- `src/Web/StellaOps.Web/src/app/routes/evidence.routes.ts`
+- `src/Web/StellaOps.Web/src/app/features/evidence-thread/evidence-thread.routes.ts`
+- `src/Web/StellaOps.Web/src/app/features/workspaces/auditor/auditor-workspace.routes.ts`
+- `src/Web/StellaOps.Web/src/app/features/workspaces/developer/developer-workspace.routes.ts`

+## Delivery Tracker
+
+### FE-UET-001 - Freeze mount points and URL contract
+Status: DONE
+Dependency: none
+Owners: Developer (FE), Product Manager
+Task description:
+- Freeze the canonical URLs, breadcrumb behavior, and owning entry points for evidence threads and persona workspaces before reconnecting any routes.
+- Keep the URL contract under `/evidence` so the routes remain anchored in the shipped Evidence shell.
+
+Completion criteria:
+- [x] Canonical URL contract is recorded in the execution log.
+- [x] Evidence-thread and persona-workspace host entry points are identified.
+- [x] No separate top-level persona menu is introduced.
+
+### FE-UET-002 - Reconnect evidence-thread routes
+Status: DONE
+Dependency: FE-UET-001
+Owners: Developer (FE)
+Task description:
+- Mount `EVIDENCE_THREAD_ROUTES` under the canonical Evidence route family and wire entry points from current evidence surfaces where the drill-in is meaningful.
+
+Completion criteria:
+- [x] Evidence threads are reachable from the canonical `/evidence` route family.
+- [x] Entry points come from mounted evidence surfaces instead of dead navigation.
+- [x] Route titles and breadcrumbs align with current Evidence-shell patterns.
+
+### FE-UET-003 - Reconnect auditor and developer workspace routes
+Status: DONE
+Dependency: FE-UET-001
+Owners: Developer (FE)
+Task description:
+- Mount the auditor and developer workspace routes under the canonical Evidence route family with an explicit role segment or equivalent bounded pattern.
+- Ensure the workspaces behave as alternate evidence lenses, not as a parallel product shell.
+
+Completion criteria:
+- [x] Auditor and developer workspaces are reachable from canonical Evidence-owned URLs.
+- [x] Route ownership remains inside the Evidence shell.
+- [x] Persona workspace entry points are bounded to relevant mounted evidence contexts.
+
+### FE-UET-004 - Verify and document route reconnection
+Status: DONE
+Dependency: FE-UET-002
+Owners: Test Automation, Documentation author
+Task description:
+- Add focused route and host-integration coverage for the reconnected evidence routes and document the shipped slice.
+
+Completion criteria:
+- [x] Route-focused Angular tests cover the reconnected evidence-thread and persona-workspace URLs.
+- [x] Checked-feature note exists under `docs/features/checked/web/`.
+- [x] UI plan/task docs reflect the evidence-route reconnection.
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2026-03-08 | Sprint created from the orphan-revival batch to reconnect evidence threads and persona workspaces under the canonical Evidence shell. | Project Manager |
+| 2026-03-08 | FE-UET-001: Canonical URL contract frozen. Threads at /evidence/threads, workspaces at /evidence/workspaces/{auditor,developer}/:artifactDigest. No top-level persona menu. | Developer (FE) |
+| 2026-03-08 | FE-UET-002: EVIDENCE_THREAD_ROUTES mounted under /evidence/threads via loadChildren in evidence.routes.ts. Breadcrumb data added to thread routes. | Developer (FE) |
+| 2026-03-08 | FE-UET-003: AUDITOR_WORKSPACE_ROUTES and DEVELOPER_WORKSPACE_ROUTES mounted under /evidence/workspaces/{auditor,developer} via loadChildren. Breadcrumb data added. | Developer (FE) |
+| 2026-03-08 | FE-UET-004: Route-focused tests created at evidence.routes.spec.ts. Checked-feature note at docs/features/checked/web/evidence-thread-persona-workspaces-routes.md. | Developer (FE) |
+
+## Decisions & Risks
+- Decision: evidence threads and persona workspaces remain Evidence-owned drill-ins, not standalone products.
+- Risk: persona workspace routes could sprawl into a parallel persona-navigation scheme if mounted carelessly.
+- Mitigation: freeze the URL contract first and require all routes to live under `/evidence`.
+
+## Next Checkpoints
+- 2026-03-09: Evidence-owned URL contract frozen.
+- 2026-03-11: route-reconnection criteria agreed.
