Cognitive Architecture as Database Operations: Complete Synthesis and Advanced Specifications
Daqing Sun · PhilPapers (PhilPapers Foundation)
We present the complete and definitive database-theoretic reformulation of cognitive architecture, synthesizing prior foundational work with advanced specifications developed through systematic theoretical refinement. Cognition operates through three orthogonal binary dichotomies: two at the premise level (Integrity type: Entity vs Referential; Row cardinality: Multi-row vs Single-row) and one at the join level (Lead premise: Grand-lead vs Small-lead). Critical architectural innovation: Join vigilance operates as an on-call attention mechanism that dynamically allocates attention to whichever key field is relevant for the current join operation. Referential integrity functions (N/T) can activate 95% attention to Primary Key (during Type 1 joins within premise bank) or Foreign Key (during Type 2 cross-premise joins), while entity integrity functions (S/F) maintain fixed proportional allocation (~20% baseline). This asymmetry creates three match probability tiers: both referential (0.90 detection rate), mixed integrity (0.19), both entity (0.04). The row dichotomy determines versioning capability: multi-row regime enables internal premise refinement through Type 1 joins (within Grand Bank or Small World), while single-row regime enforces discrete episodic processing. All architectural parameters derive from the golden ratio φ ≈ 1.618: lead premise capacity (10 rows), follow premise capacity (10/φ ≈ 3.82 rows), and universal content compatibility (1/φ² ≈ 0.382). Type 2 joins (Grand × Small vector forging) involve 10 × 3.82 = 38.2 comparisons yielding 14.6 compatible pairs universally. Type 1 joins at primary premise involve 10 × 10 = 100 comparisons yielding 38.2 compatible pairs; at auxiliary premise 3.82 × 3.82 = 14.59 comparisons yielding 5.57 compatible pairs. UMRBS (Unified Mental-Relevant Biochemical Signal) operates as universal modulator through three-pillar additivity (function preference + biological state + vector par situation), preventing exponential cognitive explosion. Pillar 2 (biological depletion) enforces a 3-4 hour hard cutoff on Type 1 sessions regardless of Pillar 1 satisfaction. Pillar 3 (vector pressure) forces reality-driven interrupts, typically terminating Type 1 work earlier via urgency-based context switches. The single-core processor constraint creates severe interrupt costs for J-types engaged in deep Type 1synthesis. The framework reveals a profound architectural tragedy: ISFJ and INTJ invest identical cognitive effort (95% internal work, same Pillar 2 depletion, same Pillar 3 interrupts) but ISFJ produces 96% fewer synthesis operations due to 4% vs 90% detection efficiency. Both types face 14.6 compatible row-pairs per table-pair join, but low join vigilance causes ISFJ to miss ~14 matches per pair that INTJ detects. This is not impoverished cognition but detection-limited access to sophisticated compatibility that exists but goes unseen. We provide 12 falsifiable empirical predictions, complete φ-based specifications for all 16 types, and type-calibrated development protocols. The framework transforms personality typology from descriptive taxonomy to computational architecture specification with precise database semantics, quantified predictions, and mechanistic explanations.
