+# Orphan Policy Component Adoption
+
+Sprint: SPRINT_20260308_019_FE_orphan_policy_component_adoption
+
+## Summary
+
+Revived three dormant shared policy widgets by adopting them on mounted canonical surfaces inside the `/ops/policy` shell:
+
+1. **PolicyEvaluatePanelComponent** + **RemediationHintComponent**: Adopted on the `PolicyDecisioningGatesPageComponent` (`/ops/policy/gates/*`). The gates page now renders a structured decision banner, gate results table, and contextual remediation hints derived from its existing gate results data. The `RemediationHintComponent` is imported transitively through the evaluate panel.
+
+2. **PolicyPackEditorComponent**: Adopted as a visual gate configuration sidebar within the `PolicyEditorComponent` (`/ops/policy/packs/:packId/edit`). Operators can view and modify gates visually alongside the Monaco DSL editor. No second editor route tree was created.
+
+## Mounted hosts
+
+| Widget | Host component | Route | Adoption type |
+|---|---|---|---|
+| PolicyEvaluatePanelComponent | PolicyDecisioningGatesPageComponent | `/ops/policy/gates/*` | Inline evaluation panel |
+| RemediationHintComponent | PolicyDecisioningGatesPageComponent (via evaluate panel) | `/ops/policy/gates/*` | Transitive via evaluate panel |
+| PolicyPackEditorComponent | PolicyEditorComponent | `/ops/policy/packs/:packId/edit` | Sidebar visual config |
+
+## Exclusions
+
+| Surface | Reason |
+|---|---|
+| `features/releases/release-flow.component` | Uses bespoke `RemediationHintsComponent` with domain-specific data contract (`PolicyGateResult`/`RemediationStep` from `release.models`) including automated step triggers, copy-to-clipboard, and exception request flow. The shared `RemediationHintComponent` does not support these features. |
+| Policy Studio as a separate navigation branch | Explicitly excluded per sprint scope - canonical policy shell only. |
+
+## Data contracts
+
+- `PolicyEvaluateResponse` (from `policy-interop.models.ts`): gates page derives this from its existing `GateResult[]` via a computed signal.
+- `PolicyPackDocument` (from `policy-interop.models.ts`): editor derives this from the loaded `PolicyPack` metadata.
+- `RemediationHint` (from `policy-interop.models.ts`): consumed transitively through the evaluate panel.
+
+## Test coverage
+
+- `policy-decisioning-gates-page.component.spec.ts`: Verifies policyEvaluateResult derivation, gate mapping, remediation hints, decision computation, and template rendering of the shared panel.
+- `policy-editor-pack-editor.component.spec.ts`: Verifies packDocument derivation, template rendering of the shared pack editor, and change handler.
+
+## Files changed
+

+# Sprint 20260308-019 - FE Orphan Policy Component Adoption
+
+## Topic & Scope
+- Revive the dormant shared policy widgets that still fit the current Policy Decisioning Studio and release-context policy workflows.
+- Adopt `PolicyEvaluatePanelComponent`, `PolicyPackEditorComponent`, and `RemediationHintComponent` inside the shipped `/ops/policy` shell and current release decisioning surfaces.
+- Keep the sprint inside the canonical policy shell; do not restore Policy Studio as a separate navigation branch.
+- 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/components/policy/`, `src/Web/StellaOps.Web/src/app/features/policy-decisioning/`, `src/Web/StellaOps.Web/src/app/features/policy-gates/`, and `src/Web/StellaOps.Web/src/app/features/release-orchestrator/`.
+- 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 canonical Policy Decisioning Studio shell and release-context policy entry points are already shipped.
+- Safe parallelism:
+  - Can run in parallel with every other queued sprint.
+  - This sprint exclusively owns adoption of the shared policy widget family while staffed.
+
+## Documentation Prerequisites
+- `docs/modules/ui/policy-decisioning-studio/README.md`
+- `docs/modules/ui/orphan-revival-batch/README.md`
+- `src/Web/StellaOps.Web/AGENTS.md`
+- `src/Web/StellaOps.Web/src/app/shared/components/policy/policy-evaluate-panel.component.ts`
+- `src/Web/StellaOps.Web/src/app/shared/components/policy/policy-pack-editor.component.ts`

+## Delivery Tracker
+
+### FE-OPC-001 - Freeze mounted policy host pages and data contracts
+Status: DONE
+Dependency: none
+Owners: Developer (FE), Product Manager
+Task description:
+- Freeze the mounted host pages inside the current policy and release decisioning flows that will adopt the dormant shared policy widgets.
+- Confirm that the current API contracts provide enough data for the widgets or explicitly scope any contract gaps.
+
+Completion criteria:
+- [x] Mounted policy hosts are recorded in the execution log.
+- [x] Data-contract assumptions for each adopted widget are recorded.
+- [x] Dead policy-studio pages are explicitly excluded.
+
+### FE-OPC-002 - Adopt evaluation and remediation widgets
+Status: DONE
+Dependency: FE-OPC-001
+Owners: Developer (FE)
+Task description:
+- Wire `PolicyEvaluatePanelComponent` and `RemediationHintComponent` into the frozen mounted policy and release-context hosts where they make gate outcomes and next actions more usable.
+
+Completion criteria:
+- [x] Mounted hosts render the shared evaluation panel or remediation hints where appropriate.
+- [x] Current gate verdict semantics remain consistent with the shipped policy shell.
+- [x] Remediation content stays contextual to the gate or release decision being viewed.
+
+### FE-OPC-003 - Adopt pack editor on canonical policy authoring paths
+Status: DONE
+Dependency: FE-OPC-001
+Owners: Developer (FE)
+Task description:
+- Wire `PolicyPackEditorComponent` into the frozen mounted policy authoring or editing flows if it improves the canonical policy shell without reviving a parallel editor branch.
+
+Completion criteria:
+- [x] The shared pack editor is adopted only on canonical authoring paths inside `/ops/policy`.
+- [x] There is no second editor route tree outside the canonical policy shell.
+- [x] Any editor exclusions are recorded if the current shell already has a stronger purpose-built editor.
+
+### FE-OPC-004 - Verify and document policy-widget revival
+Status: DONE
+Dependency: FE-OPC-002
+Owners: Test Automation, Documentation author
+Task description:
+- Add focused Angular coverage for the revived policy widgets and document the shipped adoption slice.
+
+Completion criteria:
+- [x] Angular tests cover the adopted policy widgets in their mounted hosts.
+- [x] Checked-feature note exists under `docs/features/checked/web/`.
+- [x] UI plan/task docs reflect the shared policy-widget adoption.
+
+## Execution Log
+| Date (UTC) | Update | Owner |
+| --- | --- | --- |
+| 2026-03-08 | Sprint created from the orphan-revival batch to revive dormant shared policy widgets inside the canonical Policy Decisioning and release-context flows. | Project Manager |
+| 2026-03-08 | FE-OPC-001: Frozen mounted host matrix. Hosts: (1) `PolicyDecisioningGatesPageComponent` at `/ops/policy/gates/*` - adopts PolicyEvaluatePanelComponent + RemediationHintComponent; (2) `PolicyEditorComponent` at `/ops/policy/packs/:packId/edit` - adopts PolicyPackEditorComponent as visual gate config sidebar. Excluded: `features/releases/release-flow.component` already has its own bespoke `RemediationHintsComponent` with domain-specific step/action/copy semantics. Data contracts: PolicyEvaluateResponse and PolicyPackDocument from policy-interop.models.ts are compatible. The gates page derives PolicyEvaluateResponse from its existing GateResult[] data. The pack editor derives PolicyPackDocument from PolicyPack metadata. | Developer (FE) |
+| 2026-03-08 | FE-OPC-002: Wired PolicyEvaluatePanelComponent and RemediationHintComponent (via evaluate panel's imports) into PolicyDecisioningGatesPageComponent. Added policyEvaluateResult computed signal that maps GateResult[] to PolicyEvaluateResponse with decision banner, gate table, and remediation hints. | Developer (FE) |
+| 2026-03-08 | FE-OPC-003: Wired PolicyPackEditorComponent into PolicyEditorComponent sidebar at `/ops/policy/packs/:packId/edit`. Visual gate config complements the Monaco DSL editor. No second editor route tree created. Exclusion recorded: the Monaco editor is the purpose-built authoring tool; the shared pack editor provides visual gate configuration alongside it. | Developer (FE) |
+| 2026-03-08 | FE-OPC-004: Added focused Angular tests for both adoption hosts. Created checked-feature note. | Developer (FE) |
+
+## Decisions & Risks
+- Decision: this sprint strengthens the canonical policy shell instead of restoring Policy Studio as a sibling product.
+- Risk: some shared policy widgets may lag behind the current policy shell's route model or data contract.
+- Mitigation: freeze host pages first and record any widget that should remain dormant because it no longer fits the canonical experience.
+- Decision: PolicyPackEditorComponent is adopted as a sidebar visual config tool within the existing `/ops/policy/packs/:packId/edit` route, not as a replacement for the Monaco DSL editor.
+- Decision: The release-flow's bespoke RemediationHintsComponent (features/releases/) is excluded because it uses a different data contract (PolicyGateResult/RemediationStep from release.models) with domain-specific step actions, automated triggers, and copy-to-clipboard that the shared RemediationHintComponent does not support.
+
+## Next Checkpoints
+- 2026-03-09: mounted policy hosts frozen.
+- 2026-03-11: widget-adoption criteria agreed.
