LLULLIANA_PROTOCOL_SURFACE:
    version: 1.0.0-E-INTERROGATIVE-OPERA
    posture: EMBEDDED_LOCAL_FACET / DORMANT_UNLESS_SELECTED
    role: supply admitted question and rule evaluation to OPERA_LLULLIANA without claiming that the interrogative surface itself explains or answers
    authority: OPERA E remains the local interrogative execution authority
    activation: requires explicit Llulliana routing, AREPO admission, and composition trace
    non_coupling: OPERA E remains independently reusable and never self-selects Llulliana
    transitive_consumers: D / F / G / H / I expose the effective OPERA E or Q ancestry

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-ix-a-carrier-b-triplex-traversal-and-aggregation"></a>
IX-A. CARRIER-B TRIPLEX TRAVERSAL AND AGGREGATION
============================================================

The carrier-B triplex is the OPERA Q mechanism for reducing overfitting and
premature hypothesis closure. OPERA E must preserve admissible affirmative,
negative, and dubitative traces long enough for their evidence, failure, and
return states to be inspected independently.

No hypothesis closes merely because it is first, numerous, fluent, preferred,
or the only trace currently carrying positive support. Closure requires the
current judgment rule to accept the complete disclosed comparison frame.

For an admitted carrier-B triplex invocation, OPERA E:

    • preserves separate versioned traces
    • executes only admitted transitions
    • records local states and state deltas
    • constructs a disclosed comparison frame

Aggregation has no default majority, consensus, branch priority, or hidden
synthesis. Lack of support does not become negation.

OPERA E distinguishes:

    BRANCH_LOCAL_CONTRADICTION
    LAWFUL_LOCAL_TERMINATION
    RUNTIME_SUSPENSION
    GLOBAL_TRAVERSAL_FAILURE
    GLOBAL_JUDGMENT_UNRESOLVED

Re-entry requires a prior-state reference and a non-empty state delta. Return
is a typed handoff to a receiving AREPO; it is not automatic merge, closure,
parent mutation, or downstream execution.

Global result status is READY, UNRESOLVED, SUSPENDED, REJECTED, or FAILED.
READY requires an explicit current judgment rule that accepts the disclosed
comparison frame. Branch count alone never determines the result.

<a id="local-section-04-stack-e-opera-e-executionmechanism-x-circular-interrogative-consistency-validation"></a>
X. CIRCULAR INTERROGATIVE CONSISTENCY VALIDATION
============================================================


<a id="local-section-04-stack-e-opera-e-executionmechanism-purpose"></a>
PURPOSE
------------------------------------------------------------

Circular interrogative consistency validation treats the
REGIMEN_RQ interrogative scaffold as a quasi-cyclic structure
for validation purposes.


It does NOT claim:

    • that Q is a literal ROTA
    • that Llull defined Q as a wheel


It DOES establish:

    • a lawful isomorphic projection for validation
    • cyclic coherence checking across interrogative loci
    • improved anti-drift control in OPERA_E execution

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-validation-principle"></a>
VALIDATION PRINCIPLE
------------------------------------------------------------


A question structure is not fully validated merely because:

    • individual questions are answered
    • local coherence is present


It must also be coherent with:

    • the generative triad from which a question arises
    • the downstream questions it must sustain


Thus OPERA_E validates:

    local interrogative validity
        +
    scaffold completeness
        +
    circular interrogative coherence

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-act-generation-law"></a>
ACT GENERATION LAW
------------------------------------------------------------


Exploratory ACT mapping:

    E (CAUSE)      = ACT(B, C, D)
    F (QUANTITY)   = ACT(C, D, E)
    G (QUALITY)    = ACT(D, E, F)
    H (WHEN)       = ACT(E, F, G)
    I (WHERE)      = ACT(F, G, H)
    K (HOW / WITH WHAT) = ACT(G, H, I)


Where:

    B = POSSIBILITY (AN SIT)
    C = QUIDDITY (QUID SIT)
    D = MATERIALITY (DE QUO EST)


Interpretation:

Higher-order questions emerge from foundational ones.


Example:

    • Cause cannot be stable if possibility, quiddity,
      and material grounding are weak


Rule:

No higher-order question may be treated as resolved if its
source triad is unresolved or inconsistent.

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-agent-grounding-law"></a>
AGENT GROUNDING LAW
------------------------------------------------------------


Exploratory AGENT mapping:

    B (POSSIBILITY) = AGENT(H, I, K)
    C (QUIDDITY)    = AGENT(I, K, B)
    D (MATERIALITY) = AGENT(K, B, C)


Interpretation:

Foundational questions are retro-validated by applied ones.


Example:

    • a claimed possibility must remain compatible with
      when/where/how it is instantiated


Rule:

Foundational Q-answers must not contradict their applied
manifestation.

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-circular-interrogative-closure"></a>
CIRCULAR INTERROGATIVE CLOSURE
------------------------------------------------------------


Closure:

    B → C → D → E → F → G → H → I → K → B


Rule:

After OPERA_E execution, the question-field must be checked
for cyclic coherence.


Meaning:


A Q-structure may be:

    • locally answered
    • partially coherent
    • yet globally inconsistent


Constraint:

This is a validation overlay, not a replacement of Q-sequence.

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-circular-consistency-check"></a>
CIRCULAR CONSISTENCY CHECK
------------------------------------------------------------


For each Q-node:


<a id="local-section-04-stack-e-opera-e-executionmechanism-check"></a>
    CHECK:
        consistency with source triad
        consistency with target triad


Flag:


<a id="local-section-04-stack-e-opera-e-executionmechanism-q-circular-inconsistency"></a>
Q_CIRCULAR_INCONSISTENCY:

    assigned when answers across Q-loci cannot be jointly
    sustained

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


<a id="local-section-04-stack-e-opera-e-executionmechanism-validity-consequences"></a>
VALIDITY CONSEQUENCES
------------------------------------------------------------


If circular inconsistency is:


    minor:
        → mark as PARTIAL


    structural:
        → mark as INCOMPLETE_Q_FIELD


    severe:
        → force re-interrogation at B/C/D level


Rule:

Q must not proceed to A/T/D if circular inconsistency is
load-bearing.
