Purpose#

Dimensional Compatibility determines how well a framework’s operators fit the dimensional substrate it occupies.
Compatibility influences:

dimensional stability
transition potential
collapse risk
coherence formation
regime transitions

A mismatch between operators and dimensional level is one of the most common sources of drift, collapse, and paradox exposure.

Compatibility Model#

1. Operator–Dimension Alignment#

Each operator family has natural dimensional ranges:

R (Relations) — strongest in D2–D4
T (Transitions) — strongest in D3–D5
E (Envelope) — strongest in D3–D4
L (Lineage) — strongest in D2–D3
C (Coherence) — strongest in D3–D5
B (Boundary) — strongest in D1–D3

Compatibility is high when operators fire within their natural dimensional ranges.

2. Substrate Fit#

Substrate fit measures how well the framework’s structure matches the dimensional substrate.

Indicators:

structural density
relational complexity
transition depth
boundary stability
coherence load

Good substrate fit → stable dimensional behavior.
Poor substrate fit → dimensional stress.

3. Dimensional Stress#

Dimensional stress occurs when operators or structures exceed the capacity of the current dimensional envelope.

Examples:

D2 framework attempting D3 transitions without coherence
D3 framework attempting D4 transitions without resonance
D4 framework collapsing due to paradox overload

Stress increases collapse risk.

4. Compatibility Boundaries#

Boundaries where compatibility weakens:

soft compatibility boundary — mild stress, manageable
hard compatibility boundary — transitions blocked
critical compatibility boundary — collapse likely

These boundaries often align with paradox boundaries and coherence thresholds.

Compatibility Matrices#

Operator Compatibility Matrix (Abbreviated)#

Operator	Strong In	Weak In	Notes
R	D2–D4	D0–D1, D6+	relational mapping collapses below D2
T	D3–D5	D0–D2	transitions require spatial substrate
E	D3–D4	D0–D2, D5+	envelope operators destabilize outside D3–D4
L	D2–D3	D0–D1, D5+	lineage collapses above D3
C	D3–D5	D0–D2	coherence requires stable substrate
B	D1–D3	D0, D4+	boundaries dissolve above D3
