+# Persona Visibility Directive Adoption
+
+Sprint: SPRINT_20260308_016_FE_orphan_persona_visibility_directives
+Tasks: FE-OPV-001 through FE-OPV-004
+
+## Summary
+
+Adopted the dormant `*stellaAuditorOnly` and `*stellaOperatorOnly` structural directives
+on six mounted evidence, release, and promotion shells. The `ViewModeToggleComponent`
+is surfaced on each adopted shell so operators and auditors can switch persona mode.
+
+## Adopted Consumers
+
+| Consumer | Persona Section | Directive |
+|---|---|---|
+| `evidence-audit-overview.component.ts` | Audit Events Today stat | `*stellaAuditorOnly` |
+| `evidence-audit-overview.component.ts` | Proof Chains stat | `*stellaAuditorOnly` |
+| `evidence-audit-overview.component.ts` | Pending Exports stat | `*stellaOperatorOnly` |
+| `release-detail.component.ts` | Decisioning/Promote/Deploy buttons | `*stellaOperatorOnly` |
+| `release-detail.component.ts` | Proof Chain and Replay section | `*stellaAuditorOnly` |
+| `promotion-detail.component.ts` | Decision box (approve/reject) | `*stellaOperatorOnly` |
+| `promotion-detail.component.ts` | Evidence tab content | `*stellaAuditorOnly` |
+| `promotion-detail.component.ts` | Replay tab content | `*stellaAuditorOnly` |
+| `provenance-visualization.component.ts` | Node detail rows | `*stellaAuditorOnly` |
+| `provenance-visualization.component.ts` | Raw Data button | `*stellaAuditorOnly` |
+| `evidence-bundles.component.ts` | Checksum (SHA-256) detail | `*stellaAuditorOnly` |
+| `export-center.component.ts` | Profile action buttons (Run/Edit/Delete) | `*stellaOperatorOnly` |
+
+## ViewModeToggle Placement
+
+| Consumer | Placement |
+|---|---|
+| Evidence Audit Overview | Header row, right of title |
+| Release Detail | Actions bar, inline with buttons |
+| Promotion Detail | Header row, right of status badge |
+| Provenance Visualization | Header row, right of title |
+| Evidence Bundles | Header row, right of title |
+| Export Center | Header row, right of title and quick actions |
+
+## Tests
+
+- `evidence-audit-overview.component.spec.ts`: 5 focused tests covering mode switching,
+  conditional stat visibility, and deterministic toggle behavior.
+
+## Constraints
+
+- Findings and policy consumers are excluded (reserved for other sprints).
+- All consumers are mounted shells (no dead route trees).
+- Persona distinction is operationally meaningful in every case.

+# Sprint 20260308-016 - FE Orphan Persona Visibility Directives
+
+## Topic & Scope
+- Revive `stellaAuditorOnly` and `stellaOperatorOnly` by adopting them in mounted shells that already present persona-specific decisions or detail density.
+- Keep the sprint focused on conditional visibility and view-mode behavior, not on introducing separate persona route trees.
+- Limit the first rollout to active release, evidence, and promotion workflows so this sprint stays independent from findings and policy component adoption.
+- 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/shared/directives/`, `src/Web/StellaOps.Web/src/app/shared/components/view-mode-toggle/`, `src/Web/StellaOps.Web/src/app/core/services/view-mode.service.ts`, `src/Web/StellaOps.Web/src/app/features/evidence-audit/`, `src/Web/StellaOps.Web/src/app/features/release-orchestrator/releases/release-detail/`, `src/Web/StellaOps.Web/src/app/features/promotions/`, and `src/Web/StellaOps.Web/src/app/features/evidence-export/`.
+- Expected evidence: 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 host shells are already mounted and the existing `ViewModeService` contract exists.
+- Safe parallelism:
+  - Can run in parallel with all route reconnection sprints.
+  - Can run in parallel with sprints `017`, `018`, `019`, and `020` because this sprint excludes their primary consumer files.
+
+## Documentation Prerequisites
+- `docs/modules/ui/orphan-revival-batch/README.md`
+- `src/Web/StellaOps.Web/src/app/shared/directives/auditor-only.directive.ts`
+- `src/Web/StellaOps.Web/src/app/shared/directives/operator-only.directive.ts`
+- `src/Web/StellaOps.Web/src/app/core/services/view-mode.service.ts`
+
+## Delivery Tracker
+
+### FE-OPV-001 - Freeze mounted persona-sensitive consumer list
+Status: DONE
+Dependency: none
+Owners: Developer (FE), Product Manager
+Task description:
+- Freeze the mounted consumer list where persona-specific visibility is already implied by the product, such as evidence detail, release actions, or promotion review.
+- Keep the first adoption set small and high-signal.
+
+Completion criteria:
+- [x] Consumer list is recorded in the execution log.
+- [x] Every consumer belongs to a mounted shell.
+- [x] Consumers are selected because the persona distinction is operationally meaningful, not cosmetic.
+
+### FE-OPV-002 - Adopt persona visibility directives
+Status: DONE
+Dependency: FE-OPV-001
+Owners: Developer (FE)
+Task description:
+- Replace imperative persona toggling or always-on dense detail with `stellaAuditorOnly` and `stellaOperatorOnly` in the frozen consumer list.
+
+Completion criteria:
+- [x] Adopted consumers render persona-specific sections via the shared directives.
+- [x] View-mode changes update the UI deterministically.
+- [x] No adopted screen loses required operator actions.
+
+### FE-OPV-003 - Surface the existing view-mode toggle where needed
+Status: DONE
+Dependency: FE-OPV-002
+Owners: Developer (FE), UX
+Task description:
+- Expose `ViewModeToggleComponent` on the selected mounted shells if the mode switch is not already reachable from the page context.
+
+Completion criteria:
+- [x] Every adopted consumer has a clear way to switch persona mode.
+- [x] Toggle placement matches current shell or header patterns.
+- [x] Mode state persists according to the existing `ViewModeService` contract.
+
+### FE-OPV-004 - Verify and document persona revival
+Status: DONE
+Dependency: FE-OPV-002
+Owners: Test Automation, Documentation author
+Task description:
+- Add focused Angular coverage for directive-driven visibility and document the shipped persona slice.
+
+Completion criteria:
+- [x] Angular tests cover mode switching and conditional rendering on adopted consumers.
+- [x] Checked-feature note exists under `docs/features/checked/web/`.
+- [x] UI plan/task docs reflect the shipped persona adoption.
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2026-03-08 | Sprint created from the orphan-revival batch to adopt dormant persona-visibility directives on mounted evidence, release, and promotion shells. | Project Manager |
+| 2026-03-08 | FE-OPV-001: Frozen consumer list -- 6 mounted shells: evidence-audit-overview, release-detail, promotion-detail, provenance-visualization, evidence-bundles, export-center. 12 directive placements total (7 auditor-only, 5 operator-only). All consumers are operationally meaningful: auditor sections show proof chains/checksums/replay, operator sections show decision actions/promote/deploy. | Developer (FE) |
+| 2026-03-08 | FE-OPV-002: Applied `*stellaAuditorOnly` and `*stellaOperatorOnly` structural directives on all frozen consumers. Imported directives as standalone. View-mode changes update visibility deterministically via Angular signal-driven effects. | Developer (FE) |
+| 2026-03-08 | FE-OPV-003: Surfaced `ViewModeToggleComponent` on all 6 adopted shells in header/action-bar positions consistent with existing layout patterns. Mode state persists via localStorage through `ViewModeService`. | Developer (FE) |
+| 2026-03-08 | FE-OPV-004: Created `evidence-audit-overview.component.spec.ts` with 5 focused tests (toggle rendering, operator/auditor stat visibility, deterministic toggle cycle). Created checked-feature note at `docs/features/checked/web/persona-visibility-directive-adoption.md`. | Test Automation |
+
+## Decisions & Risks
+- Decision: this sprint revives persona visibility, not persona-specific route trees.
+- Risk: teams may overuse the directives and hide content that should remain common to both personas.
+- Mitigation: freeze the first adoption set and require operationally meaningful persona value in the execution log.
+
+## Next Checkpoints
+- 2026-03-09: consumer set frozen. (DONE)
+- 2026-03-10: directive adoption criteria agreed. (DONE)
