backup_restore_preview.py DOX

Purpose

• Own the backup_restore_preview.py API endpoint.
• This module handles backup restore preview requests.
• Keep this file-level DOX profile synchronized with backup_restore_preview.py because this directory is intentionally flat.

Ownership

• backup_restore_preview.py owns the runtime implementation.
• backup_restore_preview.py.dox.md owns durable notes about responsibilities, contracts, side effects, and verification for that implementation.
• Classes:
• BackupRestorePreview (ApiHandler)
  • requires_auth(cls) -> bool
  • requires_loopback(cls) -> bool
  • async process(self, input: dict, request: Request) -> dict | Response

Runtime Contracts

• HTTP handlers must derive from helpers.api.ApiHandler; WebSocket handlers must derive from helpers.ws.WsHandler.
• Update this file whenever request payloads, authentication or CSRF requirements, response shapes, route side effects, or WebSocket event contracts change.
• BackupRestorePreview is an ApiHandler.
• BackupRestorePreview defines process(...).
• BackupRestorePreview defines requires_auth(...).
• BackupRestorePreview defines requires_loopback(...).
• Observed side-effect areas: filesystem deletion, settings/state persistence.
• Imported dependency areas include: helpers.api, helpers.backup, json, werkzeug.datastructures.

Key Concepts

• Important called helpers/classes observed in the source: request.form.get.lower, json.loads, BackupService, backup_service.preview_restore.
• Keep request/response, tool, or helper semantics documented here at the same time as source changes.

Work Guidance

• Preserve authentication, CSRF, loopback, and API-key checks unless the endpoint contract explicitly changes.
• Update frontend callers, plugin callers, and tests together when payload shape changes.
• Use helpers.api.Response for non-JSON responses, files, redirects, or status-specific replies.

Verification

• Run endpoint-specific or API/WebSocket tests for changed behavior; smoke-test browser callers when no focused test exists.
• No direct test reference was found by name search; choose the nearest behavioral test or perform a focused smoke check.
