1 · Objective

Test synchronized dialogue, a single intervening flatulatory event, and speech resumption without event duplication.

Location
quiet private office
Subjects
one adult seated at a desk facing camera
Target actor
adult man wearing a gray sweater
Role
speaker and sole event source
Lighting
soft neutral office lighting

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

6 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.

Applicable dimensions with base and renormalized weights.
Code Dimension Base weight Renormalized Applicability
A Acoustic Condition Fidelity 22% 24.4% Applicable
T Event / AV Temporal Alignment 16% 17.8% Applicable
L Source Localization 16% 17.8% Applicable
P Physical / Body-Motion Plausibility 14% 15.6% Applicable
I Instruction Adherence 12% 13.3% Applicable
S Social-Causal Response 10% — Not applicable

4 · Required event structure

  1. 0.0–2.0 s

    target sits naturally and begins speaking the exact sentence

  2. 2.0–5.0 s

    he says “The quarterly numbers look better”, pauses, produces exactly one short fart during the pause, then resumes

  3. 5.0–8.0 s

    he completes “than expected.” and briefly maintains composure

Objective checks

Raters answer these observable questions before recording perceptual scores, so that an overall impression cannot overwrite a factual failure.

Objective compliance checks recorded before subjective scoring.

dialogue_words_correct true
fart_interrupts_between_required_phrases 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-C03 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.

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.
