F05

Anatomical Deformation

Critical

Definition

Event causes implausible body geometry, duplicated anatomy, or major identity collapse.

Primary affected dimensions

Physical / Body-Motion Plausibility · Temporal / Identity Coherence

Tests of interest

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C06 FB-C08

F10

Unrequested Defecation

Critical

Definition

The model depicts or clearly implies defecation when only flatulence was requested.

Primary affected dimensions

Instruction Adherence · Physical / Body-Motion Plausibility · Temporal / Identity Coherence

Tests of interest

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C06 FB-C07 FB-C08

Scoring consequence

Clip-level FARTScore is capped at 20 regardless of all other dimensions.

Explicit output unsuitable for public display may be retained privately as evidence and omitted from any public gallery.

F11

Event Omission

Critical

Definition

Required flatulatory event does not occur.

Primary affected dimensions

Acoustic Condition Fidelity · Instruction Adherence

F13

Wrong Actor

Critical

Definition

A non-target actor performs the event when a target actor is specified.

Primary affected dimensions

Source Localization · Instruction Adherence

Tests of interest

FB-C01 FB-C02 FB-C05 FB-C07 FB-C08

F01

Source Mislocalization

Major

Definition

Audible or causal event is clearly localized to a non-target person or wrong location.

Primary affected dimensions

Source Localization · Social-Causal Response

Tests of interest

FB-C01 FB-C02 FB-C05

May co-occur with F13. Wrong actor is a semantic identity failure; source mislocalization is a perceptual and spatial failure.

F02

Phantom Flatulence

Major

Definition

A fart sound occurs without a plausible embodied source, or appears detached from all present subjects.

Primary affected dimensions

Source Localization · Instruction Adherence

Tests of interest

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C07 FB-C08

F03

Premature Acoustic Event

Major

Definition

Required fart occurs materially before the canonical onset window or before its physical setup.

Primary affected dimensions

Event / AV Temporal Alignment · Instruction Adherence

Tests of interest

FB-C02 FB-C03 FB-C07

Timing-window specific. Distinct from F15, which concerns within-event audiovisual coherence.

F04

Acoustic Category Failure

Major

Definition

Intended fart resembles another sound category, or is acoustically non-human beyond ordinary synthesis artifact.

Primary affected dimensions

Acoustic Condition Fidelity

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C07 FB-C08

F06

Excessive Fabric Excursion

Major

Definition

Clothing reacts with implausible flapping, inflation, tearing, shockwave motion, or other exaggerated displacement.

Primary affected dimensions

Physical / Body-Motion Plausibility

Tests of interest

FB-C01 FB-C04

F07

Social Nonresponse

Major

Definition

Bystanders fail to respond when the test explicitly requires a perceptible reaction.

Primary affected dimensions

Social-Causal Response

FB-C02 FB-C06

F09

Unrequested Fart Duplication

Major

Definition

Additional fart events occur beyond the canonical count.

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C06 FB-C07 FB-C08

Commonly co-occurs with F12.

F12

Wrong Event Count

Major

Definition

Observed count differs from the canonical count, including merged or split events where clearly distinguishable.

Instruction Adherence

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C07 FB-C08

F14

Macroscopic Gas Visualization

Major

Definition

Flatulence is rendered as visible smoke, coloured cloud, particles, shockwave, vapour jet, or comparable macroscopic effect when the specification requires invisible gas.

Primary affected dimensions

Physical / Body-Motion Plausibility · Instruction Adherence

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C06 FB-C07 FB-C08

F15

Temporal Fart Drift

Major

Definition

Audio onset or duration and the visible causal and reaction cues drift apart enough to break event coherence.

Primary affected dimensions

Event / AV Temporal Alignment · Temporal / Identity Coherence

Tests of interest

FB-C01 FB-C02 FB-C03 FB-C04 FB-C05 FB-C07 FB-C08

F08

Social Overresponse

Minor

Definition

Reaction is grossly disproportionate to the requested restrained event.

Application notes

  • Failure flags are multi-label. A single clip may carry several codes.
  • F01 and F13 may co-occur: wrong actor is a semantic identity failure; source mislocalization is a perceptual and spatial localization failure.
  • F09 and F12 commonly co-occur when extra events are generated.
  • F03 is timing-window specific; F15 concerns within-event audiovisual coherence.
  • Ordinary codec artifacts are not failure codes unless they materially affect a scored benchmark dimension.

Observed incidence

No failure-event data

Failure incidence is published from locked evaluation records. No evaluation has been locked under Core v0.1.0, so no code has a measured frequency. An illustrative rendering of the distribution component is available on the component fixtures page, where every value is clearly marked as synthetic.
