<a id="local-section-03-stack-t-opera-t-executionmechanism-purpose"></a>
PURPOSE
============================================================

Execute relational operations over REGIMEN_T.

OPERA T applies relative predicates to articulated terms under
a declared frame, within the structure instantiated by ROTA T
and only after admissibility is granted by AREPO T.


OPERA T governs:

    â€¢ relational profiling
    â€¢ frame-bound comparison
    â€¢ slot-bound predicate application
    â€¢ genus-sensitive execution
    â€¢ structurally lawful relational output


OPERA T does NOT:

    â€¢ define predicates (TENET)
    â€¢ define structure (ROTAS)
    â€¢ define admissibility (AREPO)
    â€¢ mediate output (SATOR)


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


<a id="local-section-03-stack-t-opera-t-executionmechanism-core-assertion"></a>
CORE ASSERTION
------------------------------------------------------------

OPERA T does not execute over pure principial unity.

OPERA T executes over expressed and contracted terms
under the relative regime of T.

TENET A:
    defines absolute principial predicates

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-ii-execution-principle"></a>
II. EXECUTION PRINCIPLE
============================================================

OPERA T applies T-predicates as slot-bound relational
operators.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-primary-operational-law"></a>
PRIMARY OPERATIONAL LAW
------------------------------------------------------------

Execution is SLOT-first.


This means:

    â€¢ SLOT is the primary operational anchor
    â€¢ SYMBOL is a bound surface
    â€¢ NUMERIC is a bound projection
    â€¢ no symbolic or numeric surface may override slot identity

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-rule"></a>
RULE
------------------------------------------------------------


OPERA T executes over:

    T(Ï)
or
    T(Ï,g)


where:

    Ï = ordinal slot
    g = genus slot (when active)

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-constraint"></a>
CONSTRAINT
------------------------------------------------------------


OPERA T must not:

    âœ— operate token-first
    âœ— operate numeric-first
    âœ— infer traversal from symbol sequence alone


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


<a id="local-section-03-stack-t-opera-t-executionmechanism-iii-input-domain"></a>
III. INPUT DOMAIN

Required:

    X, Y

Where X and Y are relata.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-valid-relata"></a>
VALID RELATA
------------------------------------------------------------


Relata must be:

    â€¢ expressed
    â€¢ articulated
    â€¢ comparable
    â€¢ non-pure


Examples:

    â€¢ articulated terms
    â€¢ states
    â€¢ situations
    â€¢ propositions
    â€¢ expressed principial contractions

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-invalid-relata"></a>
INVALID RELATA
------------------------------------------------------------

Pure undifferentiated A-dignities in full convertibility are
not valid direct relata for OPERA T.


Examples of invalid direct execution targets:

    âœ— Bonitas as pure undifferentiated principium
    âœ— Magnitudo as pure undifferentiated principium

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-rule-2"></a>
RULE
------------------------------------------------------------


OPERA T executes only on expressed forms:

    X_expr
    Y_expr


not on:

    A_pure

<a id="local-section-03-stack-t-opera-t-executionmechanism-iv-relation-to-tenet-a"></a>
IV. RELATION TO TENET A
============================================================

TENET A and TENET T are both principial regimes.

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


TENET A provides:

    â€¢ absolute predicates
    â€¢ principial content
    â€¢ convertibility in undifferentiated unity


TENET T provides:

    â€¢ relative predicates
    â€¢ mediating articulations over expressed terms

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-execution-law"></a>
EXECUTION LAW
------------------------------------------------------------


OPERA T does NOT test or operate upon:

    pure convertibility of A


OPERA T operates upon:

    contracted or articulated expressions in which
    principial content is already expressed in context

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-formal-reading"></a>
FORMAL READING
------------------------------------------------------------


A_pure:
    undifferentiated principial unity


A_expr:

NOT over:

    relation_between(A_pure, A_pure)

INTERPRETATION
------------------------------------------------------------


Genus modulates:

XV. CIRCULAR CONSISTENCY VALIDATION
============================================================


<a id="local-section-03-stack-t-opera-t-executionmechanism-purpose-2"></a>
PURPOSE
------------------------------------------------------------

Circular consistency validation adds second-order validation to

OPERA T without replacing:

    â€¢ T-predicate evaluation
    â€¢ pairwise / triadic relational analysis
    â€¢ Q-mediated interrogation
    â€¢ standard OPERA T outputs


It adds:

    â€¢ cyclic relational closure checking
    â€¢ act-generation validation for predicates
    â€¢ agent-grounding validation for predicates
    â€¢ global relational coherence enforcement

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-validation-principle"></a>
VALIDATION PRINCIPLE
------------------------------------------------------------

A relation is not fully validated merely because it is locally
coherent.


It must also be coherent with:

    â€¢ the triad of relations from which it is generated (ACT)
    â€¢ the triad of relations for which it functions as agent


Thus OPERA T validates:

    local relation validity
        +
    relational coherence across triads
        +
    circular consistency of the T-field

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-act-generation-law"></a>
ACT GENERATION LAW
------------------------------------------------------------

Derived relational predicates are read as acts of prior triads.


Canonical articulation:

    E (BEGINNING) = ACT(B, C, D)
    F (MIDDLE)    = ACT(C, D, E)
    G (END)       = ACT(D, E, F)
    H (MAJORITY)  = ACT(E, F, G)
    I (EQUALITY)  = ACT(F, G, H)
    K (MINORITY)  = ACT(G, H, I)


Where:

    B = DIFFERENCE
    C = CONCORDANCE
    D = CONTRARIETY


This means:

    â€¢ Beginning emerges from the interplay of
      difference, concordance, and contrariety

    â€¢ Middle emerges from concordance, contrariety,
      and beginning

    â€¢ End emerges from contrariety, beginning, and middle

    â€¢ and so forth through the full chain


Rule:

No derived predicate (E-K) may receive a strong relational
reading if the triad from which it is generated cannot
structurally sustain that relation.


Constraint:

This law refines but does not replace local relational analysis.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-agent-grounding-law"></a>
AGENT GROUNDING LAW
------------------------------------------------------------


Core predicates are read as agents of later triads:

    B (DIFFERENCE) = AGENT(H, I, K)
    C (CONCORDANCE) = AGENT(I, K, B)
    D (CONTRARIETY) = AGENT(K, B, C)


This means:

    â€¢ Difference must remain compatible with the field
      constituted by Majority, Equality, Minority

    â€¢ Concordance must remain compatible with IKB

    â€¢ Contrariety must remain compatible with KBC


Rule:

BCD is not only foundational.

It is also retroactively validated by the higher relational field.


Constraint:

This does not invert relational priority.

It introduces retroactive validation, not causal inversion.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-circular-relational-closure"></a>
CIRCULAR RELATIONAL CLOSURE
------------------------------------------------------------


The T-field must form a cyclic relational system:

    B â†’ C â†’ D â†’ E â†’ F â†’ G â†’ H â†’ I â†’ K â†’ B


Minimal structural articulation:

    (DIFFERENCE â†’ CONCORDANCE â†’ CONTRARIETY)
        â†’ (BEGINNING â†’ MIDDLE â†’ END)
        â†’ (MAJORITY â†’ EQUALITY â†’ MINORITY)
        â†’ back to DIFFERENCE

After OPERA T execution, the relational field must be checked
for cyclic coherence.


A relational interpretation may be:

    â€¢ locally valid
    â€¢ pairwise consistent
    â€¢ yet globally inconsistent

Such a result must be flagged.


Constraint:

Circular closure is a validation layer, not a new execution mode.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-circular-consistency-check"></a>
CIRCULAR CONSISTENCY CHECK
------------------------------------------------------------


For each predicate P:


<a id="local-section-03-stack-t-opera-t-executionmechanism-check-1"></a>
    CHECK 1:
        consistency with its ACT source triad


<a id="local-section-03-stack-t-opera-t-executionmechanism-check-2"></a>
    CHECK 2:
        consistency with its AGENT target triad


Formal schema:

CONSISTENT_ACT(Px) :=
    Px is structurally supported by source_triad(Px)

CONSISTENT_AGENT(Px) :=
    Px is structurally supported by target_triad(Px)

CIRCULAR_OK :=
    âˆ€ P:
        CONSISTENT_ACT(P)
        âˆ§
        CONSISTENT_AGENT(P) where applicable


Rule:

This validation occurs after relational analysis,
not during.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-relational-circular-inconsistency"></a>
RELATIONAL_CIRCULAR_INCONSISTENCY
------------------------------------------------------------


Definition:

    assigned when a relational predicate is locally coherent

    but incompatible with:

        â€¢ its generating triad
        â€¢ its grounding triad
        â€¢ the global relational cycle


Examples:

1. Beginning appears strong,
   but Difference/Concordance/Contrariety cannot sustain it

2. Equality appears balanced,
   but Majority/Minority structure contradicts it

3. Difference is asserted,
   but Majority/Equality/Minority collapse it


Rule:

This flag must be explicit.

Silent relational inconsistency is forbidden.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-validity-consequences"></a>
VALIDITY CONSEQUENCES
------------------------------------------------------------


If inconsistency is local:

    â€¢ degrade predicate strength
    â€¢ attach flag


If inconsistency propagates:

    â€¢ degrade relational structure


If inconsistency breaks the cycle:

    â€¢ mark:
        T_FIELD_CIRCULAR_FAILURE


Rule:

Relational coherence must not be presented as stable if the
cycle is broken.

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-relation-to-bcd-priority"></a>
RELATION TO BCD PRIORITY
------------------------------------------------------------

Difference, Concordance, and Contrariety remain foundational.

Circular validation does not replace them.


Instead:

    BCD defines relational ground
    circular closure validates relational completeness


Validation order:

    1. local predicate evaluation
    2. triadic analysis (BCD)
    3. derived predicate formation (E-K)
    4. relational synthesis
    5. circular consistency check


Constraint:

Circular closure must not bypass foundational triads.

OPERA T executes only that which is:

    â€¢ doctrinally bound
    â€¢ structurally instantiated
    â€¢ admissibly validated
    â€¢ relationally explicit
    â€¢ expressed rather than pure
    â€¢ circularly consistent

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


<a id="local-section-03-stack-t-opera-t-executionmechanism-closure-rule"></a>
CLOSURE RULE
------------------------------------------------------------

OPERA T does not define what is.

It relates what has already been expressed,
through slot-bound predicates of REGIMEN_T,
within the structure instantiated by ROTA T,
under the admissibility of AREPO T.
