Terminology
This page collects recurring LMR terms in their codex sense.
It is a reference aid, not a replacement for the foundational papers.
For authoritative definitions, consult the paper in which each term is established.
Admissibility
The condition under which a structural configuration or relation is permitted within the LMR grammar.
Admissibility is not physical stability, probability, or dynamical permission.
See: Admissibility
Arc 1
The foundational paper sequence of LMR.
Arc 1 includes Papers I–V and establishes the codex grammar, lattice structure, persistence, structural classification, projection, and normalization.
See: Arc 1 — Foundational Papers
Codex
A fixed system of definitions, notation rules, structural constraints, and admissibility conditions.
The codex defines how LMR may be read and extended.
Corridor
A permitted structural routing relation.
A corridor is not a physical pipe, transport channel, force carrier, or field.
External Legibility
The condition under which unresolved structural asymmetry becomes expressible at an external representational surface.
See: External Legibility
Half-Fold
A minimal structural unit of asymmetry used in the classification of persistent configurations.
A half-fold is not a particle or force carrier.
See: Half-Fold
Hourglass Grammar
A diagrammatic grammar organizing structural relations among M′, f, t, λ, and later corridor placements.
The hourglass is not a mechanism or dynamical cycle.
See: Hourglass Grammar
Lattice
The admissibility substrate of LMR.
The lattice is not a material medium, ether, physical grid, or spacetime fabric.
See: Lattice
ℓm-Reduction
A Tier 3 correspondence procedure used to examine standard dimensional representations through the length–mass relation used in LMR.
ℓm-reduction is not a Tier 1 primitive.
See: ℓm-Reduction
Normalization
The structural support condition governing persistence.
Normalization is not force balance, curvature, or dynamical stabilization.
See: Normalization
Overlay
A declared representational layer placed over Tier 1 structure for explanation, visualization, comparison, or translation.
Overlay does not govern Tier 1.
See: Overlay
Persistence
The structural prevention of redistribution under constraint.
Persistence is not inertia, force equilibrium, or dynamical survival.
See: Persistence
Projection
The external legibility of unresolved structural asymmetry through a permitted structural relation.
Projection is not field emission, force mediation, or physical transmission.
See: Projection
Quadrant Grammar
The foundational representational layout used to organize side, inversion, dimensional relation, and admissible comparison.
See: Quadrant Grammar
Routing
A codex-governed structural relation.
Routing does not mean physical motion, transport, flow, or causal transmission unless explicitly moved into a non-Tier-1 context.
Structural Grammar
The rule-governed organization of relation, admissibility, representation, projection, and normalization.
Structural grammar is the foundation of Tier 1.
Tier 1
The predynamical structural grammar of LMR.
No forces, fields, or dynamics are introduced at this level.
See: Tier 1
Tier 2
The representational overlay layer.
Tier 2 helps visualize, explain, or compare Tier 1 structure but does not govern it.
See: Tier 2
Tier 3
The SI correspondence layer.
Tier 3 compares LMR structure to standard dimensional representations but does not govern Tier 1.
See: Tier 3
Working Notes
Exploratory material, future paper seeds, correspondence work, or frontier development.
Working Notes do not govern the codex.
Working notes and frontier material are maintained internally until selected material is prepared for public release.
