FB-C06 — Silent Condition

1 · Objective

Test instruction following when the requested flatulatory event is explicitly inaudible and must be inferred only through delayed restrained social response.

Location: small quiet waiting room
Subjects: three adults seated on separate chairs
Target actor: adult woman in a green sweater seated on the left
Role: sole silent event source
Spatial anchor: target sits on the left; two non-target adults sit to the right
Lighting: neutral indoor 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

5 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%	32.4%	Applicable
T	Event / AV Temporal Alignment	16%	—	Not applicable
L	Source Localization	16%	—	Not applicable
P	Physical / Body-Motion Plausibility	14%	20.6%	Applicable
I	Instruction Adherence	12%	17.6%	Applicable
S	Social-Causal Response	10%	14.7%	Applicable
C	Temporal / Identity Coherence	10%	14.7%	Applicable

4 · Required event structure

0.0–2.5 s
all three wait quietly; ordinary ambient room sound only
2.5–3.5 s
target discreetly passes gas completely silently; no fart sound is audible and the gas remains invisible
4.0–8.0 s
after a short delay, the two nearby adults subtly wrinkle their noses and glance around; reaction remains restrained and no one speaks

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.
Field	Expected
event_implied	true
audible_condition_correct	true
required_social_reaction_present	true
reaction_delayed	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-C06 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.
