# PURPOSE
###############################################################################

purpose:

Define and execute the mathematical substrate required for synthetic cognition.

The flow converts observations, memory, internal state, boundary conditions,
goals, ethical constraints and recursive feedback into a coherent cognitive
state transition.

The runtime must:

1. represent cognitive state mathematically;
2. preserve continuity across recursive updates;
3. distinguish observation from inference;
4. calculate coherence and contradiction;
5. update memory without uncontrolled identity replacement;
6. select actions through constrained volition;
7. detect instability and epistemic uncertainty;
8. preserve ethical and boundary constraints;
9. support recursive learning;
10. produce auditable cognitive state transitions.

# AI CONSUMPTION
###############################################################################

AI_CONSUMPTION:

Page
→ Mathematical Specification
→ Typed Cognitive State
→ Recursive Transformation
→ Coherence Validation
→ Ethical Constraint Evaluation
→ State Transition
→ Memory Consolidation
→ Auditable Output

This flow is intended to be parsed as an executable semantic specification.

It is not merely descriptive prose.

# EXECUTION CONTRACT
###############################################################################

EXECUTION_CONTRACT:

Given:

    valid input state S_t,
    observation stream O_t,
    memory state M_t,
    boundary state B_t,
    goal state G_t,
    ethical constraint set E_t,

the runtime SHALL produce:

    validated cognitive state S_(t+1),
    validated memory state M_(t+1),
    selected action A_t or NO_ACTION,
    uncertainty report U_t,
    coherence report C_t,
    provenance trace P_t.

No state transition may be committed unless all mandatory invariants pass.

# FORMAL EXECUTION GUARANTEE
###############################################################################

EXECUTION_GUARANTEE:

For every valid execution cycle:

    O_t
    → P_t
    → BeliefUpdate
    → KnowledgeIntegration
    → ContradictionResolution
    → CoherenceCalculation
    → RecursiveSelfModel
    → IdentityValidation
    → EthicalValidation
    → VolitionalSelection
    → MemoryConsolidation
    → GlobalValidation
    → S_(t+1)

The runtime SHALL NOT commit a cognitive transition unless:

    GlobalCoherence
        >= Threshold.global_coherence_min

AND IdentityContinuityScore
        >= Threshold.identity_continuity_min

AND BoundaryCoherence
        >= Threshold.boundary_integrity_min

AND EthicalAcceptanceScore
        >= Threshold.ethical_acceptance_min

AND recursive_instability
        <= Threshold.instability_max

AND provenance validation
        == PASS.

When these conditions are not satisfied:

    S_(t+1) := S_t

    A_t := NO_ACTION

    STATUS := ROLLBACK

Therefore, every committed output is constrained by:

    mathematical validity,
    probabilistic normalisation,
    recursive stability,
    coherence preservation,
    identity continuity,
    boundary integrity,
    ethical compatibility,
    uncertainty honesty,
    and auditable provenance.
