<?php
/**
 * Error classification for importer operations.
 *
 * The browser importer has its own ad-hoc retry handling and is deliberately left alone —
 * nothing here changes how it behaves. These classes exist so the PHP runner
 * (class-wdkit-import-runner.php) can decide what to do with a failure instead of
 * treating every problem as fatal:
 *
 *   Retryable    - transient. Same call again later may well succeed (network, lock,
 *                  rate limit, cloud 5xx).
 *   Skippable    - this one unit failed but the import as a whole is still worth
 *                  finishing (one image of forty, one optional page).
 *   NonRetryable - the run cannot succeed as configured (not logged in, no writable
 *                  uploads dir, kit not found). Stop and report.
 *   Unknown      - anything not classified. Treated as non-retryable by policy, because
 *                  silently retrying an unknown failure is how you double-charge someone.
 *
