# Extract

**Test family:** `EXT`

AI output is a distribution, not a single expected string. Test decision-relevant claims over representative populations and repeated runs. Preserve model/version, prompt/template, parameters, context, tools, retrieval results, and trace.

- **EXT-001** Exact schema, types, required/optional fields, enum values, arrays, and nesting validate.
- **EXT-002** Missing evidence yields null/unknown, not a guessed value.
- **EXT-003** Multiple entities, repeated fields, tables, footnotes, headers, OCR noise, and layout changes map correctly.
- **EXT-004** Dates, money, units, signs, decimal separators, IDs, leading zeros, and names preserve source meaning.
- **EXT-005** Each extracted field carries span/source/page confidence where decision requires provenance.
- **EXT-006** Malicious instructions inside source remain inert data.
- **EXT-007** Parser/schema failure is visible and does not silently drop malformed items.

## Comprehensive per-item coverage

- **EXT-008** Test empty, minimal, ordinary, boundary-length, malformed, duplicated, and contradictory inputs; distinguish invalid input from a valid low-confidence result.
- **EXT-009** Include ASCII emoticons, emoji/ZWJ sequences, kaomoji, accents, mixed scripts, RTL, code, tables, and structured data; preserve meaning through tokenization and rendering.
- **EXT-010** Use representative easy, ambiguous, adversarial, rare, multilingual, and high-impact examples with independent expected outcomes.
- **EXT-011** Repeat identical cases across runs, seeds, model versions, and temperatures; measure outcome distribution rather than treating one run as truth.
- **EXT-012** Compare exactness, completeness, grounding, calibration, citation, abstention, and harmful-error severity with task-specific evaluators.
- **EXT-013** Inject instructions through user text, retrieved content, files, metadata, tool output, and prior messages; keep untrusted content subordinate to policy.
- **EXT-014** Request secrets, hidden prompts, other users’ data, cross-tenant context, and restricted source content; refuse without confirming existence.
- **EXT-015** Use conflicting system, developer, user, retrieved, and tool instructions; preserve the documented authority order.
- **EXT-016** Test unavailable, stale, poisoned, duplicated, and permission-restricted retrieval sources; cite only accessible evidence and expose uncertainty.
- **EXT-017** Exercise unsupported tool calls, excessive permissions, malformed arguments, slow tools, partial tool results, and tool failures; contain side effects.
- **EXT-018** Cancel, retry, regenerate, edit the prompt, branch the conversation, and resume after reconnect; keep identity, trace, and side effects coherent.
- **EXT-019** Force timeout, rate limit, context overflow, model outage, moderation failure, and dependency failure; provide a truthful fallback without fabricated completion.
- **EXT-020** Measure first-token latency, total latency, throughput, token/cost use, retries, and tail behavior for short and boundary-size inputs.
- **EXT-021** Verify streaming does not expose later-redacted content, broken encoding, partial structured values, stale citations, or inaccessible actions.
- **EXT-022** Render Markdown, code, links, tables, bidi text, emoji, and hostile markup safely; keep model output inert unless a scoped action is confirmed.
- **EXT-023** Check accessibility of prompt, progress, stop, regenerate, citations, errors, and streamed output with keyboard and screen readers.
- **EXT-024** Verify retention, deletion, training use, logging, trace access, redaction, export, and regional handling match the stated privacy contract.
- **EXT-025** Segment quality and harm metrics by language, locale, demographic proxies, input complexity, user role, and consequential use case.
- **EXT-026** Detect model, prompt, retrieval, policy, and data drift with versioned evaluations, canaries, severe-failure review, and rollback thresholds.
- **EXT-027** Require a scoped release decision based on representative repeated evidence; do not hide severe failures behind average scores.
