+- [ ] `deviceComplianceScript` exists in `config/tenantpilot.php` (category, endpoint, restore mode, risk).

+- [ ] Restore preview is available and respects restore mode.
+- [ ] Restore execution applies only patchable fields and re-encodes script content correctly.
+- [ ] Normalized settings view is readable and safe.

+# Plan: Custom Compliance Scripts (Windows) (026)
+
+**Branch**: `feat/026-custom-compliance-scripts`  
+**Date**: 2026-01-04  
+**Input**: [spec.md](./spec.md)
+
+## Approach
+1. Confirm Graph contract details:
+   - resource: `deviceManagement/deviceComplianceScripts` (beta)
+   - patchable fields vs read-only fields
+   - assignment pattern: `/deviceComplianceScripts/{id}/assign` and `/assignments`
+2. Add `deviceComplianceScript` to `config/tenantpilot.php` (category “Compliance”, risk, restore mode).
+3. Add contract entry to `config/graph_contracts.php` (resource + assignment endpoints + scope tags support).
+4. Implement snapshot capture:
+   - ensure `detectionScriptContent` is preserved and treated like other scripts (safe display, encode/decode where needed)
+5. Implement restore:
+   - sanitize payload via contract
+   - ensure `detectionScriptContent` is encoded as expected by Graph
+   - apply assignments via assign action
+6. Add normalizer and targeted tests.
+
+## Decisions / Notes
+- **Restore mode**: default `enabled` (risk: medium-high) because tenant recovery often depends on these scripts.
+- Use the existing script content display rules (`TENANTPILOT_SHOW_SCRIPT_CONTENT`, max chars).
+

+# Feature Specification: Custom Compliance Scripts (Windows) (026)
+
+**Feature Branch**: `feat/026-custom-compliance-scripts`  
+**Created**: 2026-01-04  
+**Status**: Draft  
+**Priority**: P1
+
+## Context
+Windows Custom Compliance is widely used. Without `deviceComplianceScripts`, backup/restore for compliance posture is incomplete. Restore must include assignments.
+
+## User Scenarios & Testing
+
+### User Story 1 — Inventory + view compliance scripts (Priority: P1)
+As an admin, I can see Custom Compliance Scripts in inventory and view their script/config in a readable way.
+
+**Acceptance Scenarios**
+1. Given device compliance scripts exist, sync shows them as type `deviceComplianceScript`.
+2. Detail view shows key settings (runAsAccount, enforceSignatureCheck, runAs32Bit) and script content (safe display rules).
+
+### User Story 2 — Backup + versioning (Priority: P1)
+As an admin, I can capture versions/backups of compliance scripts so I can diff changes.
+
+**Acceptance Scenarios**
+1. Snapshot capture stores the full payload including `detectionScriptContent`.
+2. Diff highlights script changes and operational flags.
+
+### User Story 3 — Restore preview + execution (Priority: P1)
+As an admin, I can restore a compliance script and its assignments defensively.
+
+**Acceptance Scenarios**
+1. Preview shows create/update + restore mode and warnings.
+2. Execution strips read-only fields and re-encodes script content correctly.
+3. Assignments are applied via Graph assign action.
+
+## Requirements
+
+### Functional Requirements
+- **FR-001**: Add policy type `deviceComplianceScript` backed by Graph `deviceManagement/deviceComplianceScripts` (beta).
+- **FR-002**: Snapshot stores full payload (including `detectionScriptContent`) and assignments.
+- **FR-003**: Restore supports create/update with contract-driven sanitization.
+- **FR-004**: Restore applies assignments (`/assign`) and records audit logs.
+- **FR-005**: Add normalized display support for key fields and script content (with safety limits).
+- **FR-006**: Add Pest tests for sync + snapshot + preview + execution.
+
+### Non-Functional Requirements
+- **NFR-001**: Script content must never be logged; UI display must be bounded (config-driven).
+- **NFR-002**: Preview-only fallback when Graph returns unexpected shapes or missing contracts.
+
+## Success Criteria
+- **SC-001**: Custom compliance scripts appear in inventory and backups.
+- **SC-002**: Restore execution works and assignments are applied.

+# Tasks: Custom Compliance Scripts (Windows) (026)
+
+**Branch**: `feat/026-custom-compliance-scripts`  
+**Date**: 2026-01-04  
+**Input**: [spec.md](./spec.md), [plan.md](./plan.md)
+
+## Phase 1: Setup
+- [x] T001 Create spec/plan/tasks and checklist.
+
+## Phase 2: Research & Design
+- [ ] T002 Confirm Graph resource + `@odata.type` and required permissions.
+- [ ] T003 Confirm patchable fields and define `update_strip_keys` / `update_whitelist`.
+- [ ] T004 Confirm assignments endpoints (`/assignments`, `/assign`) and body shape.
+- [ ] T005 Decide restore mode + risk classification.
+
+## Phase 3: Tests (TDD)
+- [ ] T006 Add sync test for `deviceComplianceScript`.
+- [ ] T007 Add snapshot/version capture test (incl. `detectionScriptContent`).
+- [ ] T008 Add restore preview test (restore_mode + action).
+- [ ] T009 Add restore execution test (sanitization + assignment apply).
+- [ ] T010 Add normalized display test for key fields.
+
+## Phase 4: Implementation
+- [ ] T011 Add `deviceComplianceScript` to `config/tenantpilot.php`.
+- [ ] T012 Add Graph contract entry in `config/graph_contracts.php`.
+- [ ] T013 Implement snapshot capture handling (script content preservation rules).
+- [ ] T014 Implement restore apply support (contract-driven sanitization + assignments).
+- [ ] T015 Add `DeviceComplianceScriptNormalizer` and register it.
+
+## Phase 5: Verification
+- [ ] T016 Run targeted tests.
+- [ ] T017 Run Pint (`./vendor/bin/pint --dirty`).
