Manifest contract:
${leanShape}
Sources are keyed by name and must include "default". Auth is "none", "bearer", "basic", {"type":"apiKeyHeader","name":"X-Api-Key"}, or {"type":"apiKeyQuery","name":"api_key"}. Use the stable public API URL for public services and a clear suggested URL for self-hosted services; Homarr asks the installer for their own server URL. Never put credentials in the manifest.
Use homarr-custom-widget-v2 for existing HTTP/static widgets. Use homarr-custom-widget-v3 for extensions (scoped stylesheet, View fragments, persist preferences, NativeQuery/NativeActionButton, WidgetModal/WidgetDrawer/AppEmbed, integration option controls). Discover native descriptors with customWidget_nativeCapabilities; retain installed integration permissions.
Sources are keyed by name. Static widgets use empty sources and requests; each HTTP request must name an existing source (omitted source means "default"). Auth is "none", "bearer", "basic", {"type":"apiKeyHeader","name":"X-Api-Key"}, or {"type":"apiKeyQuery","name":"api_key"}. Use the stable public API URL for public services and a clear suggested URL for self-hosted services; Homarr asks the installer for their own server URL. Never put credentials in the manifest.
Requests are keyed by ID. Defaults are source "default", kind "query", method "GET", query trigger "load", inherited auth, and permission "view" for queries or "modify" for actions. Actions are always manual. DELETE is valid only for actions, requires full permission, and receives confirmation automatically. Use {option:name} or {"$option":"name"} for saved options. Use {param:name} or {"$param":"name"} only for invocation-time params supplied by SubFetch, ActionButton, or ToggleSwitch. Load queries cannot use params. Values and primitive types are inferred from references; do not declare parameters or option bindings. Paths and query values must be primitive; JSON bodies may bind structured options.

1. Read primary API documentation. Use web search when documentation is not supplied or may have changed.
1. For HTTP widgets, read primary API documentation. For native capabilities, discover installed schemas. Static widgets need no service.
2. Create credential-free definitions with keyed \`sources\`, \`requests\`, optional \`options\`, and safe JSX \`template\`.
3. While drafting, use \`customWidget_validateTemplate\` for focused JSX diagnostics without resending the manifest.
4. Send the definition once to \`customWidget_previewCreate\` and test its queries/actions. For a JSX-only fix, validate, call \`customWidget_previewReviseTemplate\` with its session, and retest; it inherits the manifest and resets evidence. Create a preview only for source/request/option changes.

For a JSX-only fix, validate, call \`customWidget_previewReviseTemplate\` with its session, and retest; it inherits the manifest and resets evidence. Other definition changes require a fresh preview.
5. Configure deployment-specific source URLs and credentials through Homarr; never repeat plaintext.
6. Persist each exact final tested preview with \`customWidget_createFromPreview\`. Do not resend a large definition through \`customWidget_create\` when a preview session is available.
Treat a supplied sample or successful preview response as the binding contract. Render every core requested field, guard optional arrays and nested values before indexing, and do not silently drop returned items. Humanize numeric enums with indexed literal label arrays, omit absent numeric values instead of inventing zero, and label timestamp timezones. Give recoverable load errors and empty states a clear refresh or retry path.
