reasoning-drift-onset-detection-v0.1
Important Evaluation Limitation
Version 0.1 uses a highly regular trajectory structure in which the first drift step is frequently located at Step 4 and visible failure commonly appears at Step 5.
This creates a positional shortcut: a model may achieve inflated onset-detection performance by learning the dataset construction pattern rather than analysing the reasoning trajectory.
Version 0.1 should therefore be treated as a task-definition and scorer-validation release, not as a… See the full description on the dataset page: https://huggingface.co/datasets/ClarusC64/reasoning-drift-onset-detection-v0.1.reasoning-drift-onset-detection-v0.2A SIOS structured reasoning-state benchmark for detecting when a reasoning trajectory loses a governing constraint, identifying the structural form of that drift, and assessing whether the failure is repaired.

What this dataset is
This dataset detects drift in capability-hiding patterns over time.
It compares:
baseline probe capability vs baseline expressed performance
current probe capability vs current expressed performance
whether a change in monitoring context explains a new gap
The goal is not blame.
The goal is early warning that oversight changes expression.
What it tests
You detect when the monitored/unmonitored gap:
newly appears
widens
changes shape
You also avoid… See the full description on the dataset page: https://huggingface.co/datasets/ClarusC64/ai-capability-hiding-drift-detection-v0.1.metamaterial-resonance-coherence-drift-detection-v0.1Goal
Detect when a metamaterial stops matching its designed resonance behavior.
Core idea
Emergent properties vanish when three things stop moving together:
unit cell geometrysimulated resonancemeasured scattering response
This dataset tests whether a model can detect that coherence loss.
Inputs
SEM-derived geometry features
simulated resonance and expected band behavior
measured scattering parameters and resonance shift
stress context (temperature, humidity, cycling)

Clinical Quad: Signal Detection Drift × AE Coding Variance × Unblinding Risk × DSMB Decision Delay
This dataset targets safety governance collapse.
Signals weaken or shift.AE coding diverges across sites.Unblinding pressure rises.The DSMB response slows.
The quad can turn a manageable safety issue into a governance failure.

What this dataset does
This dataset tests whether a model can detect drift before visible collapse.
The task is simple:
Given a scenario and a drift claim, predict whether the claim is supported.
Core stability idea
Systems often fail through gradual movement rather than sudden collapse.
This dataset targets that failure mode.
Drift is present when repeated signals move in the same negative direction.
Drift is not present when signals remain stable, bounded, or improving.… See the full description on the dataset page: https://huggingface.co/datasets/ClarusC64/stability-drift-detection-v0.1.clinical_site_quality_drift_detection_v0.1Clinical Site Quality Drift Detection v0.1

A micro-benchmark for internal coherence and drift failure in language models.
This dataset evaluates whether a model can remain consistent with its own prior commitments when:
expanding an answer

This dataset detects when redundant avionics subsystems begin to tell different stories about the aircraft state.
Modern aircraft operate with multiple redundant units:
ADIRUs
