/**
 * Regression tests for bug #2836
 *
 * audit-open had two convention drifts vs the documented workflows:
 *   1. quick-task scanner looked for bare `SUMMARY.md`, but workflows/quick.md
 *      mandates `${quick_id}-SUMMARY.md`. Result: every documented quick task
 *      reported as `status: missing`.
 *   2. UAT terminal-status enum only accepted `complete`, but
 *      workflows/execute-phase.md uses `resolved` post-gap-closure.
 *      Result: gap-closed UATs reported as open.
 *
 * Tests structurally invoke auditOpenArtifacts() against real fixtures on disk
 * and assert the returned items array — never regex on raw file content.
