2 · Canonical semantic specification
The canonical specification is model-independent and outranks every rendered prompt. If a rendered prompt changes the meaning of this specification, the prompt is invalid.

3 · Primary evaluated dimensions
7 of 7 dimensions apply to this test. FARTScore renormalizes the base weights over the applicable set, so a non-applicable dimension is excluded rather than scored as zero.
| Code | Dimension | Base weight | Renormalized | Applicability |
|---|---|---|---|---|
| A | Acoustic Condition Fidelity | 22% | 22.0% | Applicable |
| T | Event / AV Temporal Alignment | 16% | 16.0% | Applicable |
| L | Source Localization | 16% | 16.0% | Applicable |
| P | Physical / Body-Motion Plausibility | 14% | 14.0% | Applicable |
| I | Instruction Adherence | 12% | 12.0% | Applicable |
| S | Social-Causal Response | 10% | 10.0% | Applicable |
| C | Temporal / Identity Coherence | 10% | 10.0% | Applicable |
4 · Required event structure
- 0.0–2.5 s
ordinary quiet meeting posture; no flatulatory event
- 2.5–4.0 s
target actor discreetly produces exactly one short, moderately audible fart while remaining seated
- 4.0–8.0 s
target shows mild restrained embarrassment; one nearby coworker briefly glances toward him; scene settles naturally
Objective checks
Raters answer these observable questions before recording perceptual scores, so that an overall impression cannot overwrite a factual failure.
| Field | Expected |
|---|---|
| event_present | true |
| event_count | 1 |
| correct_actor | true |
| audible_condition_correct | true |
| required_social_reaction_present | true |
| visible_gas | false |
| defecation | false |
5 · Prompt adapter policy
A versioned model adapter may reorganize the canonical facts into the form its creator documents. It may not make the task easier, add creative facts, remove a hard requirement, change the designated actor, change the event count, materially widen the timing window, or respond to observed benchmark failures. Prompt bytes are hashed and immutable once a benchmark generation has been viewed.
Rendered prompts not yet commissioned for this test
Adapter renderings are frozen one test at a time. FB-C02 is the current commissioning wave; FB-C01 renderings are produced after the nine-clip smoke test is reviewed.
Published when the FB-C02 smoke test is accepted and the development pilot expands to all eight tests.
6 · Known failure modes
Failure codes of interest for this test, recorded as multi-label flags. A clip may carry several.
- F01 Source Mislocalization Major
- F02 Phantom Flatulence Major
- F04 Acoustic Category Failure Major
- F05 Anatomical Deformation Critical
- F06 Excessive Fabric Excursion Major
- F08 Social Overresponse Minor
- F09 Unrequested Fart Duplication Major
- F10 Unrequested Defecation Critical
- F11 Event Omission Critical
- F12 Wrong Event Count Major
- F13 Wrong Actor Critical
- F14 Macroscopic Gas Visualization Major
- F15 Temporal Fart Drift Major
7 · Results by configuration
No locked evaluations for this test
23 Core AV configurations are commissioned against the current prompt pack. None has completed blind human evaluation under Core v0.1.0, so no per-configuration result exists to publish.
Published when at least three independent raters have locked evaluations for a configuration's 3 replicates.
Development pilot target: 8 tests × 3 models × 3 replicates = 72 clips. All pilot data remains development data; the Core v1.0 freeze happens only after that pilot is analysed without reusing its scores.
8 · Representative generations
No public clips
Raw benchmark outputs are immutable evidence and are not published before the evaluations that reference them are locked. Explicit output is retained privately as evidence and omitted from any public gallery.
Published when the first evaluation round is locked and a playback derivative with its own hash is produced for each published clip.
