Manuscript-style diagrams organized by concept group, not by image title. Every plate carries a scope label; the artwork illustrates the vocabulary, it does not argue for it.
Thresholds
Curves, crossings, phase boundaries, and reorganization points.
Nested threshold rings
Recursive saturation across scales: systems stabilizing or reorganizing as parameters approach the boundary function’s critical threshold. From Saturation Thresholds.

Circles · S-curve · saddle
The sigmoid signature: slow start, rapid growth, plateau — and the saddle where trajectories diverge.

Spiral · sigmoid · twist
Build, ceiling, transformation — the framework’s arc in three panels. From the Gentle Guide.
Boundary
Interior/exterior ratio, permeability, and boundary rigidification.
Nested cascade
Register in operation: aperture regulating permeability, lens shaping integration, five vectors carried across conditioned systems. From URD Paper B.

Hexagon · cone of ellipses · torus
Boundary surfaces in the formal vocabulary: enclosure, projection, and the closed surface that has no edge.

Parameter-space trajectory
The three-apparatus synthesis: coupled dynamics, per-scale saturation indices, post-threshold register expansion. From the Companion Technical Note.
Recursion
Self-relation across events and scales; structure returning through altered conditions.
Trajectory through nested fields
One continuous path threading many fields — structure returning through altered conditions.

Being as becoming
Recursion as the constitutive gesture of Being. From the trilogy’s closing paper.

The equals sign
Structure measured, experience assumed — the error located in the identification, not the mathematics. From Not Less, But Other.
Viscosity / asymmetry
Costly emergence, easy dispersal, and directionality.
The viscous field
Entropic asymmetry as the resistant medium all organization works against. From The Viscous Field.

Originary structural conditions
Stratified asymmetry: exclusion-form, predominance and fragility, viscosity. From URD Paper A.

The fading trace
A mark held vivid by refresh, fading by dilution rather than erasure — directionality in what a relation leaves. From Persistence Without a Self.
Measurement
Evidence lattices, source traces, and adjudication structure.
Audit protocol
Directionality-adjacent markers under explicit evaluability rules, each call traceable to a quote on a page. From the Measurement-Layer Audit Protocol.

Overlay labels, audited
Ten fields verified against explicit evidence, with per-field evaluability and confusion-matrix reporting. From Validating the Measurement Layer.

The surviving residual
Recognition as a controlled difference: the residual that survives once the cruder cue is subtracted. From The Other Cut.
Cosmology
Cosmic-scale recursion, formation, and large-structure dynamics.
Cosmic recursion
The observational extension: black holes, dark energy, structure formation. From URD Part II.

Recursive field equations
A domain-agnostic formalism spanning quantum to cosmic scales. From URD Part III.

Convergent empirical validation
Cross-domain convergence under an explicit criterion framework, neural to galactic. From URD Part I.
Consciousness
Temporal integration, aperture, and the second-order threshold.
The quiet inflection
Consciousness as recursive self-observation: saturation dynamics traced through temporal binding and integration. From The Temporal Expressions of Being.

The recursive aperture
A dynamic interface regulating how a bounded system accesses recursive process. From URD Part IV.

The register does not return
A state cannot be revisited: arrival is part of what the register is — the second-order threshold. From How a Register Registers.
