/**
 * Workflow Verification: Freshness Watchlist — R9FE-105 + R6UXS-012
 * Session: ed72dafd-2ec0-4e39-bee4-40b570b4fc96
 *
 * Verifies the freshness workflow changes in this session:
 *
 * R9FE-105: "Check again" re-run button migrated from ad-hoc useState to
 *   useMutationButton — canonical error surfacing + double-submit guard.
 *   The combined anyRunInFlight guard prevents a header re-run + form submit race.
 *
 * R6UXS-012: TableFilterBar replaces the old Collapsible custom controls.
 *   Filter triggers are now inline (not hidden behind a collapsible), using
 *   id="filter-<key>" format, with per-filter chip display + clear-all.
 *
 * === States exercised ===
 * A. Completed state: "Check again" (useMutationButton) present + active
 * B. Completed state: TableFilterBar filters are inline (not collapsible)
 * C. Completed state: TableFilterBar shows action_type filter
 * D. Zero console errors and zero failed XHR during page load
 *
 * === Notes ===
 * Scope derived from diff — no SUCCESS_CRITERIA / WORKFLOW_BLAST_RADIUS files present.
 * Shares seeding helpers with the existing freshness-watchlist.spec.ts to avoid duplication.
