The Structural Tension

Two PDE implementations exist — and the transformation between them IS the article's argument:

coaia-pde (Extractive Era)

• StcMapper.extractIntents() — 395 lines, regex mining
• INTENT_VERBS — 72 verbs scanned mechanically
• direction: MedicineWheelDirection — singular (categorize, don't relate)
• ceremony: string — hardcoded ceremony names from a constant
• No confidence scores, no ambiguity tracking

mcp-pde (Relational Era)

• PdeEngine.buildPrompt() — ~80 lines, relational container
• directions: DirectionMap — Record<Direction, DirectionItem[]> (relate, don't categorize)
• confidence: number on every claim (epistemological humility)
• AmbiguityFlag[] — the system can say 'I'm not sure'
• Lineage declared in type file header

Wilson-Mapped Code Evidence

Transformation	Wilson Pillar
direction (singular) → directions (DirectionMap)	Relational Ontology
INTENT_VERBS regex → LLM system prompt	Epistemology (relational knowing)
No ambiguity → AmbiguityFlag[]	Epistemology (honoring uncertainty)
Four Directions last → first	Methodology (ceremony)
No lineage → lineage in header	Axiology (accountability)
StcMapper 395 LOC → PdeEngine ~80 LOC	Methodology (paradigm shift)

Key Quote for Article

The code didn't add Indigenous knowledge — it stopped subordinating the Indigenous knowledge it already held.
