🧭 Drift Detection
Drift is not sentiment, engagement, or narrative change alone. It is a vector‑level displacement across the five axes of media physics:
[S, D, A, N, T]
📐 What Drift Measures#
Drift captures changes in:
- Signal Integrity (S) — rising or falling fidelity
- Distribution Topology (D) — centralization, fragmentation, or re‑networking
- Attention Dynamics (A) — volatility, spikes, burnout
- Narrative Coherence (N) — alignment, conflict, collapse
- Temporal Cadence (T) — acceleration, compression, slowdown
A system with high drift is structurally unstable, even if its current basin appears stable.
🔢 Computing Drift#
Drift is computed as the difference between two MediaVectors:
Δ = currentVector – previousVector
Magnitude is calculated using Euclidean distance:
magnitude = sqrt(ΔS² + ΔD² + ΔA² + ΔN² + ΔT²)
This magnitude determines the drift category.
🧬 Drift Categories#
The MSM Analyzer classifies drift into four categories:
Micro Drift#
Small, routine adjustments.
- Low invariant strain
- No basin pressure
- Normal narrative or attention fluctuation
Meso Drift#
Meaningful directional movement.
- One or more invariants rising
- Early basin tension
- Narrative wobble or attention irregularity
Macro Drift#
Large structural movement.
- Multiple invariants strained
- Basin boundaries approaching
- Distribution or narrative instability
Regime Shift#
System‑level reconfiguration.
- Invariants breaking
- Basin transition imminent or underway
- Cascade, collapse, or reconstruction conditions
Regime shifts are rare but high‑impact.
🧩 Drift Signatures#
Different axes produce different drift signatures:
- High ΔA + High ΔT → cascade or burnout
- High ΔN + Low ΔS → narrative collapse
- High ΔD + High ΔN → fragmentation
- High ΔS + High ΔN → reconstruction
- High ΔT + Low ΔS → epistemic decay
These signatures help interpret why drift is occurring.
🌀 Drift and Basins#
Drift determines whether the system is:
- Settling deeper into its current basin
- Moving toward a neighboring basin
- Escaping its attractor entirely
- Crossing into cascade or collapse
- Climbing into reconstruction
Basin classification tells you where the system is.
Drift tells you where it’s going.
🎛 Drift and Modes#
Modes are strongly influenced by drift magnitude:
- Stable → micro drift
- Tension → micro or meso drift
- Drift → meso or macro drift
- Cascade → macro drift
- Collapse → macro or regime shift
- Reconstruction → meso drift with rising S and N
Drift is the primary driver of mode transitions.
🔄 Drift and Transitions#
Transitions occur when drift crosses structural thresholds:
- Basin → Basin
- Mode → Mode
- Stable → Tension → Drift → Cascade → Collapse → Reconstruction
The Analyzer uses drift magnitude and direction to determine:
- Trigger type
- Severity
- Trajectory
- Expected next basin or mode
Drift is the earliest and most reliable indicator of systemic change.
📦 Output: MediaDrift#
The Analyzer returns:
{
delta: MediaVector,
magnitude: number,
category: "micro" | "meso" | "macro" | "regime_shift"
}
This output feeds directly into transition detection and longitudinal analysis.
