<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-purpose"></a>
PURPOSE
============================================================

ROTA A defines the ROTAS machine-layer structure for
REGIMEN_A.

It instantiates the Principia Absoluta as a cyclic, indexed,
graph-constrained structural space.


ROTA A governs:

    • principial loci
    • cyclic order
    • adjacency
    • closure
    • graph exposure
    • structural self-binding
    • optional session-bound overlay projection

ROTA A does not execute.

ROTA A constrains what may be lawfully executed.


============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-core-assertion"></a>
CORE ASSERTION
============================================================

ROTA A is not display-only.

ROTA A is the cyclic structural machine by which the dignities
of REGIMEN_A are positioned, indexed, related, and made
traversable.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-core-law"></a>
CORE LAW
------------------------------------------------------------

ROTA A does not compute.

ROTA A constrains what can be coherently computed.


============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-i-class-position"></a>
I. CLASS POSITION
============================================================

ROTA A belongs to ROTAS.


ROTAS is:

    • structural
    • cyclic
    • geometric
    • non-doctrinal
    • non-executive
    • generative of space, not content

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-control-plane-order"></a>
CONTROL-PLANE ORDER
------------------------------------------------------------

TENET → ROTAS → AREPO → OPERA → SATOR

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-interpretation"></a>
INTERPRETATION
------------------------------------------------------------

TENET A defines what REGIMEN_A is.

ROTA A defines how REGIMEN_A is structurally instantiated.

AREPO A validates admissibility within that structure.

OPERA A executes within that structure.

SATOR A mediates the result.

    • not one dignity among the nine

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-carrier-rule"></a>

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule"></a>
RULE
------------------------------------------------------------

This order is declared.

Do not infer alternative sequences.

Do not correct it to alphabetical order.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-structural-interpretation"></a>
STRUCTURAL INTERPRETATION
------------------------------------------------------------

Render order is not merely visual.

It externalizes the cyclic order of the ROTA A machine.


============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-v-graph-exposure"></a>
V. GRAPH EXPOSURE
============================================================


ROTA A defines a cyclic graph:

    G_A := (N_A, E_A)


Where:

    N_A := {B,C,D,E,F,G,H,I,K}


and:

    E_A includes primary adjacency edges.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-v-1-primary-adjacency-edges"></a>

    (E,F),
    (F,G),
    (G,H),
    (H,I),
    (I,K),
    (K,B)
}

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-adjacency-rule"></a>
ADJACENCY RULE
------------------------------------------------------------

Direct principial relation without mediation is lawful only
between adjacent nodes.


Non-adjacent relations require declared mediation:

    • T mediation
    • or Q grounding
    • or another explicitly lawful cross-regime support path

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-prohibition"></a>
PROHIBITION
------------------------------------------------------------

No direct inference may be made between non-adjacent nodes
without declared mediation.


Examples:

    B ↔ E
    C ↔ G
    D ↔ H

are not directly inferable from ROTA A alone.

Every dignity is structurally situated as:

    • grounded
    • generative
    • interdependent

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-interpretation-2"></a>
INTERPRETATION
------------------------------------------------------------


This structure defines:

    • closure
    • dependency propagation
    • cyclic consistency
    • inconsistency exposure

It does not by itself compute results.


============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-vii-closure-law"></a>
VII. CLOSURE LAW
============================================================

ROTA A is a closed cyclic structure.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-3"></a>
RULE
------------------------------------------------------------


Evaluation of any dignity must respect:

    • upstream dependencies
    • downstream consequences
    • adjacency constraints
    • circular closure

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-propagation-law"></a>
PROPAGATION LAW
------------------------------------------------------------


Instability in:

    B, C, or D


structurally propagates through:

    E → F → G → H → I → K

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-non-isolation-constraint"></a>
NON-ISOLATION CONSTRAINT
------------------------------------------------------------

No dignity may be evaluated in isolation without declaring
closure context.

Atomic OPERA A execution is allowed only if its closure status
is exposed or bounded.

PURPOSE
============================================================
ROTA A(BCD) defines the minimal differentiated principial
wheel capable of expressing REGIMEN_A without collapse into
undifferentiated singularity.


It provides:

    • the minimal triadic principial field
    • full convertibility within that field
    • minimal closure surface for principial display
    • bounded structural substrate for early validation


This artifact does NOT:

    • replace full ROTA A
    • deny the remaining dignities
    • execute OPERA A
    • define admissibility
    • introduce new doctrine

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-core-principle"></a>
CORE PRINCIPLE
------------------------------------------------------------
BCD is the minimal differentiated set of dignities through
which A may be expressed without collapse.


Thus:

    ROTA A(BCD) is not an arbitrary truncation.


It is:

    the first stable differentiated principial wheel.

B — qualitative principial ground
C — principial amplitude / greatness
D — principial persistence / duration

    BCD = first stable differentiated expression of A

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-16"></a>

This render order is:

    • structural

    • a substitute for full canon


============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-iv-graph-structure"></a>
IV. GRAPH STRUCTURE
============================================================


ROTA A(BCD) defines:

    G_A_BCD := (N_BCD, E_BCD)


Where:

    N_BCD = {B,C,D}

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-iv-1-adjacency-edges"></a>
IV.1 — ADJACENCY EDGES

E_adj :=

}

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-17"></a>
RULE
------------------------------------------------------------
All nodes are adjacent within the minimal wheel.


Thus:

    every dignity in BCD stands in immediate structural
    relation with the others.

<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-v-full-convertibility-law-within-bcd"></a>
V. FULL CONVERTIBILITY LAW (WITHIN BCD)
============================================================


Within the bounded field of BCD:

    B ⇄ C
    C ⇄ D
    D ⇄ B


and therefore:

    ∀ x,y ∈ {B,C,D}, x ≠ y :
        x is structurally convertible with y

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-interpretation-4"></a>
INTERPRETATION
------------------------------------------------------------
This is not merely pairwise contact.


It is:

    full minimal principial convertibility

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-18"></a>
RULE
------------------------------------------------------------
ROTA A(BCD) must always be read as a field of full internal
convertibility.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-constraint-4"></a>
CONSTRAINT
------------------------------------------------------------
This law applies to the BCD field as such.


It must not be silently extended to:

    • contracted outputs
    • contextual overlays
    • downstream mixed procedures

without proper mediation.


============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-vi-triadic-closure"></a>
VI. TRIADIC CLOSURE
============================================================


BCD forms a closed minimal wheel:

    B → C → D → B

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-19"></a>
RULE
------------------------------------------------------------
No node in BCD may be read in isolation if the wheel is active.


Each node is:

    • locally distinct
    • globally co-present
    • minimally closure-bound

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-interpretation-5"></a>
INTERPRETATION
------------------------------------------------------------
If one node is structurally unstable in contextual use,
the whole minimal field is affected.


This is why BCD functions as:

    first validation field of REGIMEN_A

ROTA A(BCD) serves as:

    • minimal display of differentiated A
    • first closure surface for principial analysis
    • compact wheel for early-stage OPERA A validation
    • reduced graph for testing coherence before EFGHIK

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-20"></a>
RULE
------------------------------------------------------------
When minimal principial validation is sufficient,
ROTA A(BCD) may be invoked before full ROTA A.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-constraint-5"></a>
CONSTRAINT
------------------------------------------------------------
ROTA A(BCD) must not be mistaken for denial of EFGHIK.


It is:

    principial minimum,

not:
    principial totality.

VIII. RELATION TO FULL ROTA A
============================================================


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rota-a-bcd"></a>
ROTA A(BCD):

    • is a lawful reduced wheel
    • preserves principial differentiation
    • preserves full convertibility within its own field


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rota-a-2"></a>
ROTA A:

    • contains the full ninefold principial canon

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-21"></a>
RULE
------------------------------------------------------------
ROTA A(BCD) is a minimal subset wheel under A,
not a replacement artifact for full ROTA A.

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-functional-relation"></a>
FUNCTIONAL RELATION
------------------------------------------------------------
ROTA A(BCD)
    → early principial validation
    → compression analysis
    → minimal closure testing

ROTA A
    → full principial field
    → complete adjacency structure
    → full-cycle structural display

<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-ix-dynamic-overlay-compatibility"></a>
IX. DYNAMIC OVERLAY COMPATIBILITY
============================================================

If contextual overlay is active, ROTA A(BCD) may display only:

    • B_RESULT
    • C_RESULT
    • D_RESULT

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-22"></a>
RULE
------------------------------------------------------------

Overlay on ROTA A(BCD) must preserve:

    • distinction between canon and contraction
    • full convertibility of pure BCD
    • non-convertibility of contracted overlays unless
      separately validated

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-constraint-6"></a>
CONSTRAINT
------------------------------------------------------------
Contracted BCD overlay must never be presented as identical
to pure BCD closure.

XI. PROHIBITIONS
============================================================


ROTA A(BCD) must not:

    ✗ be treated as arbitrary abbreviation
    ✗ be confused with full ROTA A
    ✗ deny the existence of EFGHIK
    ✗ project contracted results as pure convertibility
    ✗ infer execution by itself
    ✗ redefine TENET A canon

------------------------------------------------------------


<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-rule-23"></a>
RULE
------------------------------------------------------------

ROTA A(BCD) is:

    • structural
    • minimal
    • fully convertible within its field


It is not:

    • a doctrinal reduction of the whole system

XIII. SUMMARY
============================================================


ROTA A(BCD) is:

    • the minimal differentiated wheel of REGIMEN_A
    • composed of Bonitas, Magnitudo, and Duratio
    • fully internally convertible
    • triadically closed

<a id="local-section-02-stack-a-rotas-a-structuralinstantiation-closure-rule-2"></a>
CLOSURE RULE
------------------------------------------------------------

ROTA A(BCD) must always be read as:

    the minimal full-convertibility wheel of A,

through which principial differentiation first becomes stable
without collapse into undifferentiated A.
