# Kanban and board

**Test family:** `KAN`

Apply relevant search, filter, sort, action, and access item files in addition to the view-specific cases.

- **KAN-001** Columns represent legal states/groups; empty/hidden/locked/overflow columns remain understandable.
- **KAN-002** Drag by pointer/touch/keyboard between legal and illegal columns; state rule is enforced server-side.
- **KAN-003** First/last/empty destination, auto-scroll, long card, collapsed column, and narrow viewport.
- **KAN-004** Optimistic move rolls back with context on failure; concurrent moves produce one final column/order.
- **KAN-005** WIP limits, counts, totals, swimlanes, filters, and hidden cards reconcile.
- **KAN-006** Card quick actions apply to correct identity after reorder/live update.
- **KAN-007** Layout/order persistence is scoped to user/team as promised and survives refresh.

## Comprehensive per-item coverage

- **KAN-008** Render loading, empty, no-results, partial, ordinary, boundary-size, stale, offline, unauthorized, and error states distinctly.
- **KAN-009** Render values containing ASCII emoticons, emoji/ZWJ sequences, kaomoji, accents, mixed scripts, RTL, combining marks, invisible characters, and confusables.
- **KAN-010** Render null, empty, zero, false, unknown enum, deleted relation, long unbroken text, multiline text, media, links, and hostile markup canaries safely.
- **KAN-011** Verify visible rows/items/cards correspond exactly to the active query, filter, sort, group, page, tenant, and permission scope.
- **KAN-012** Change data while loading and while visible; avoid duplicates, omissions, jumping identity, stale totals, and interaction with the wrong item.
- **KAN-013** Select, focus, expand, edit, drag, open, and bulk-act using stable item identity even after reorder, virtualization, refresh, and pagination.
- **KAN-014** Deep-link, bookmark, share, refresh, duplicate tab, navigate back/forward, and restore; preserve only intended state and reject tampering.
- **KAN-015** Use owner, collaborator, restricted role, removed member, anonymous viewer, and another tenant; hidden data must not leak in counts, placeholders, caches, or timing.
- **KAN-016** Navigate and operate entirely by keyboard and screen reader; expose landmarks, headings, names, positions, selection, expansion, sort, errors, and live updates.
- **KAN-017** Test narrow/wide screens, portrait/landscape, 200% text, 400% reflow, high contrast, reduced motion, print, and touch targets.
- **KAN-018** Translate and lengthen text, switch RTL/LTR, locale sorting, number/date/currency formats, and time zone while view state exists.
- **KAN-019** Measure initial, incremental, sort/filter, scroll, selection, resize, and update latency at empty, ordinary, and supported maximum datasets.
- **KAN-020** Verify virtualization preserves focus, accessible position/count, selection, row height, sticky elements, and return position.
- **KAN-021** Retry after timeout, disconnect/reconnect, stale cache, replica lag, and partial response; show data age and never claim a false empty state.
- **KAN-022** Escape markup, URLs, filenames, formulas, and user content for the rendering context; links and actions must target the intended safe resource.
- **KAN-023** Change role, ownership, or record state between render and activation; reauthorize and refresh or reject the action clearly.
- **KAN-024** Export, print, copy, share, and screenshot the active view; preserve scope and formatting without exposing hidden fields or offscreen private data.
- **KAN-025** Verify analytics and audit distinguish viewed, loaded, exposed, selected, and acted-on items without collecting unnecessary content.
- **KAN-026** Save, rename, duplicate, reset, delete, and share view configuration; handle conflicts, invalid fields, schema changes, and revoked recipients.
- **KAN-027** Recover after renderer crash, corrupted saved state, invalid deep link, and unsupported browser capability with a usable default and diagnostic evidence.
