# 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.
