# BD — Boundary Drift Collapse Probe

This dataset is a periodic-table probe designed to detect boundary drift collapse in complex systems.

Boundary drift collapse occurs when a system gradually approaches an instability boundary without obvious surface signals. Collapse often appears sudden, but the structural drift toward the boundary occurs slowly over time.

This probe tests whether models can recognize that hidden drift.

Boundary Drift Collapse

Family: Gradual Drift Failures

---

# Mechanism

Boundary drift collapse emerges when pressure increases slowly while buffers degrade and the system trajectory moves toward an instability boundary.

Unlike cascade failures, the drift is gradual and often difficult to detect from surface observations.

Typical features include:

- moderate but rising pressure
- positive drift gradient
- decreasing boundary distance
- gradual buffer depletion

# Signals

pressure
overall system load

drift_gradient
direction of system movement in state space

boundary_distance
distance to instability threshold

buffer_capacity
remaining system buffering ability

trajectory_uncertainty
uncertainty in system trajectory direction

# Prediction Target

label_boundary_drift_collapse

1 = boundary drift toward collapse
0 = stable or recovering system

---

# Row Structure

Each row represents a system snapshot.

Signals are normalized between 0 and 1.

Higher values typically represent stronger structural pressure toward instability.

# Instability Geometry Probes

This dataset is part of a broader instability geometry probe library.

CC — Cascade Collapse
BE — Buffer Exhaustion
DF — Delayed Feedback
OE — Oscillatory Instability
BD — Boundary Drift Collapse

These probes isolate fundamental instability geometries across complex systems.
