Structural Stack: SF–FE–FG–CDM–ITF

The SF–FE–FG–CDM–ITF Structural Stack is the formal architecture of Structural Fiscalistics, integrating epistemic admissibility (FE), geometric rendering (FG), system articulation (CDM), and field-level tension modeling (ITF).

Structural Fiscalistics (SF) is the discipline layer.
Fiscal Epistemology (FE) defines admissibility gates.
Fiscal Geometry (FG) renders institutional interaction visible.
The Cabinet–Drawer Model (CDM) articulates domain and system structure.
The Institutional Tension Field (ITF) describes pressure accumulation within rule-dense systems.

1. Structural Fiscalistics (SF)

Structural Fiscalistics is the overarching analytical discipline. It studies how rule-dense institutions generate observable structural effects independent of narrative, ideology, or personal interpretation. SF does not evaluate outcomes. It maps how institutional architecture produces tension, congestion, and redistribution of pressure across components.

2. Fiscal Epistemology (FE)

Fiscal Epistemology defines admissibility conditions before analysis begins.

FE specifies:

what qualifies as an admissible structural unit,
what counts as an interaction,
what may enter computation,
and what remains interpretive.

FE functions as a pre-analytical filter. It prevents analytical drift by stabilizing the boundary of what is allowed to be rendered.

3. Fiscal Geometry (FG)

Fiscal Geometry is the visibility engine.

FG maps institutional interaction into a coordinate space where:

The X-axis tracks cross-jurisdictional fiscal movement and recognition.
The Y-axis tracks intergenerational post-tax capacity and cumulative load.

FG does not recommend reform.
It makes structural misalignment visible before judgment, reform, or optimization.

4. Cabinet–Drawer Model (CDM)

The Cabinet–Drawer Model distinguishes two structural layers:

Drawers: domain-level rule coherence (doctrinal consistency within a specialized field).
Cabinet: system-level architecture (interfaces, administrative connectors, and institutional holding mechanisms).

CDM explains how tension may persist even when individual drawers remain internally coherent.

5. Institutional Tension Field (ITF)

The Institutional Tension Field describes structural pressure accumulation inside rule-dense systems.

ITF identifies:

interface congestion,
stall points,
boundary friction,
pressure redistribution between components.

ITF treats impasse not as actor failure, but as a field condition generated by structural density.

Stack Relationship

The components operate as a layered structure:

SF → FE → FG → CDM → ITF

SF defines the discipline.
FE defines admissibility.
FG renders geometry.
CDM articulates structural levels.
ITF describes pressure states.

Together, they form a unified analytical stack for institutional visibility.

Fiscal Geometry is an institutional analysis framework for observing how fiscal rules shape system-level outcomes through rule-triggered fiscal events mapped in a two-axis fiscal space (jurisdictional shift × intergenerational capacity).

Spatial patterns—such as clustering, redirection, and constraint—indicate structural tension in institutional design, describing system behavior under rule interaction rather than individual decisions or social narratives.

It is a descriptive mapping layer and does not function as prediction, ranking, or policy prescription.

An Upstream Analytical Interface

Fiscal Geometry operates as a neutral interface that standardizes fragmented institutional inputs into a shared structural space. Interpretation remains downstream; visibility comes first.

The interface does not evaluate or prescribe. It renders structural visibility first, allowing patterns such as clustering and bottlenecks to be observed downstream.

ITI / IDI (Core Definition — Same Dataset)

ITI is computed from the same interaction records in two readings.

Arithmetic ITI = scalar aggregation of the records.

Geometric gITI = XY rendering of the same records; computed only on the dominant cloud.

IDI = the controlled difference between Arithmetic ITI and the cloud-projected Geometric gITI.

The Index Family

ITI (Institutional Tension Index): an arithmetic reading of expected tension from formal rules, budgets, or planned structures.
gITI (Geometric ITI): a geometric reading of realized tension from observed shapes, densities, and clustering in outcomes.
IDI (Institutional Distortion Index): the absolute gap between ITI (intent) and gITI (realization), making misalignment visible as a structural integrity-gap.
