 - Legacy settings (`legacy-settings`): one `FAIL` for each per-feature settings file of an earlier version (telemetry, remotes, upload, task tracker) that is still there. Nothing reads them any more, so the settings they hold are not in effect; the fix is `tools/wikitool config migrate`.
 - Synced folder (`sync-folder`): a `WARN` when the git directory, links and junctions resolved, lies under a folder named by `OneDrive`, `OneDriveCommercial` or `OneDriveConsumer` (compared without regard to case on Windows) or under `~/Library/CloudStorage/` (macOS); `OK` otherwise, never a `FAIL`.
 - Backup (`backup`): the `backup` section absent is `OK`, malformed is a `FAIL`. Configured, a `WARN` when `<target>/git` is not a bare repository, `origin` does not push there, or - with `machine_data` true - no machine-data backup exists yet; otherwise `OK` with the age of the last machine-data backup.
+- Page export (`export`): the `export` section absent is `OK`, malformed is a `FAIL`; otherwise `OK` listing each target with its handler, folder and whether it runs after `publish`.
 - Intake channels (`upload-intake`): the channels of the `intake` section with their handler, and how many submissions wait in `quarantine/`. Absent is `OK` and means no channel - no `submit` tool, nothing to collect; malformed is a `FAIL`, and so is an `mcp-upload/` of an earlier version that still holds submissions (the message names the command that moves it). A `folder` channel whose `path` does not exist is a `WARN`.
 - Task tracker: the `tasks` section present, absent or malformed - absent is `OK` (no tracker configured), malformed is a `FAIL`. When `WIKITOOL_TASKS_CONFIG` is set, the profile it names is read instead of the `tasks`, `superproductivity` and `caldav` sections and the finding names it; a set variable that names no file is a `FAIL`, never `OK`.
 - For a configured `superproductivity` provider, the configured `access` path's own state: `access: "api"` reports whether its local REST API answers `GET /health` with a ready renderer right now, `access: "snapshot"` whether a backup file is ready. The other access path is never attempted, and neither state is ever a `FAIL`.
