# Progress, meter, skeleton

**Test family:** `PRG`

- **PRG-001** Zero/start/middle/near-complete/complete/failed/cancelled and indeterminate states are visually and programmatically distinct.
- **PRG-002** Value, min/max, units, and status copy are truthful; never show 100% before durable completion.
- **PRG-003** Progress is monotonic unless rollback/recalculation is explained; retry/resume does not jump deceptively.
- **PRG-004** Long work exposes cancellation/background behavior and a result/history link after navigation.
- **PRG-005** Frequent updates are throttled without freezing input or flooding screen-reader announcements.
- **PRG-006** Skeleton approximates final layout, avoids severe shift, and does not trap focus or masquerade as content.
- **PRG-007** Meter thresholds/colors have text/value alternatives and correct low/high/optimum semantics.

## Comprehensive per-item coverage

- **PRG-008** Exercise unavailable, permission-denied, idle, initializing, active, paused, completed, canceled, failed, and recovered states.
- **PRG-009** Use adjacent names, captions, metadata, or pasted text containing ASCII emoticons, emoji/ZWJ sequences, kaomoji, RTL, combining marks, and long values.
- **PRG-010** Start through pointer, keyboard, touch, switch, voice, automation, and supported device controls; expose equivalent state and one action.
- **PRG-011** Deny, grant, revoke, and change OS/browser permission while idle and active; explain consequences and stop access promptly.
- **PRG-012** Disconnect, reconnect, sleep/wake, background/foreground, rotate, resize, switch devices, and change network quality during use.
- **PRG-013** Force unsupported format, codec, capability, device, browser, version, and hardware acceleration; fall back truthfully.
- **PRG-014** Use empty, tiny, ordinary, boundary-size, malformed, truncated, corrupt, and adversarial inputs without crash or unbounded work.
- **PRG-015** Use inert markup, script, URL, path, filename, metadata, template, and structured-payload canaries; isolate untrusted content.
- **PRG-016** Attempt cross-origin, cross-tenant, unauthorized, sandbox escape, clipboard, device, and local-resource access; enforce least privilege.
- **PRG-017** Double-start, double-stop, repeat, retry after timeout, and race two sessions or devices; prevent duplicate work and state confusion.
- **PRG-018** Navigate away, refresh, crash, restore, expire the session, and resume offline/online; define preservation, cleanup, and recovery.
- **PRG-019** Verify keyboard path, accessible role/name/state, focus, announcements, captions/alternatives, contrast, reflow, target size, and reduced motion.
- **PRG-020** Test locale, RTL, translated/long labels, input methods, regional formats, and unsupported glyphs without corrupting data.
- **PRG-021** Measure initialization, interaction, processing, rendering, memory, CPU/GPU, battery, bandwidth, and cleanup at normal and boundary load.
- **PRG-022** Inspect DOM, device buffers, temporary files, caches, URLs, logs, telemetry, crash reports, previews, and exports for sensitive leakage.
- **PRG-023** Stop, cancel, undo, clear, delete, and revoke; release devices, handles, workers, object URLs, temporary data, and permissions.
- **PRG-024** Change access or ownership after content is loaded or a capability is granted; reauthorize before save, share, export, or commit.
- **PRG-025** Verify telemetry and audit identify capability, actor, target, permission decision, duration, failure, retry, and cleanup without recording sensitive payload.
- **PRG-026** Test concurrent components competing for the same device, shortcut, clipboard, focus, storage, worker, or media resource.
- **PRG-027** Recover from renderer, worker, process, device, storage, and network failure without false success, orphaned capture, or unrecoverable data loss.
