Block 04 Statement
This entry defines how density is classified, verified, and used to determine the stability and admissibility of nodes within the continuity system.
Density is a structural property, not a judgment.
Density Definition
Density is the degree to which a state is composed of independently verifiable, internally consistent elements.
Density is evaluated structurally and does not depend on outcome quality or desirability.
Density Classes
- High Density
- Multiple independent anchors
- Internal consistency across elements
- Coherence reconstructable without interpretation
- Suitable as a stable node
- Medium Density
- Partial independent anchoring
- Coherence reconstructable with constraints
- May be traversed but not used as a primary anchor
- Low Density
- Limited anchoring
- High reconstruction cost
- Does not expand the envelope
- Zero Density
- No verifiable anchors
- Coherence cannot be reconstructed
- Non-admissible by definition
Verification Rule
Density classification requires:
- observable structure,
- independent verification paths,
- consistency under re-evaluation.
Unverifiable density claims are invalid.
Density and Envelope Interaction
- Only high-density nodes may expand the envelope.
- Medium-density nodes may exist within the envelope but do not expand it.
- Low- and zero-density regions are excluded from expansion logic.
Scope of Authority
This block governs:
- node stability evaluation,
- domain admission thresholds,
- envelope expansion eligibility.
It does not:
- assert proof (Block 02),
- redefine geometry (Block 01),
- override invariants (Constitution).
Immutability Clause
This Block 04 entry is immutable once posted.
Any refinement must be introduced as a new Block 04 entry with a higher sequence number.
Closure
This entry establishes density as a measurable, non-interpretive property governing stability and expansion within the continuity framework.
