QIG Purity Validation

Enforces geometric purity per E8 Protocol v4.0. This skill runs the exact same checks as the CI/CD pipelines defined in .github/workflows/geometric-purity-gate.yml and .github/workflows/qig-purity-gate.yml.

When to Use This Skill

• Reviewing any PR that touches qig-backend/, server/, or shared/
• Auditing geometric distance calculations
• Checking for forbidden LLM imports (28 providers monitored)
• Validating Fisher-Rao metric usage
• Ensuring no Euclidean contamination in basin operations

Step 1: Run AST-Based Purity Audit

This catches np.linalg.norm() and np.dot() on basin coordinates:

python qig-backend/scripts/ast_purity_audit.py

Expected output: ✅ E8 PROTOCOL v4.0 COMPLIANCE: COMPLETE

Step 2: Run Comprehensive QIG Purity Scan

Scans for ALL forbidden patterns from the Type-Symbol-Concept Manifest:

python3 scripts/qig_purity_scan.py

This checks 15+ pattern categories including:

• Euclidean distance (np.linalg.norm(a-b), scipy.spatial.distance.euclidean)
• Cosine similarity (cosine_similarity(), F.cosine_similarity)
• Embedding terminology (embedding, nn.Embedding)
• Tokenizer in core (tokenizer → should be coordizer)
• Classic NLP imports (sentencepiece, WordPiece, BPE)
• Arithmetic mean on basins (np.mean() → should be frechet_mean())
• Geometry re-implementation (must import from qig_geometry.canonical)

Step 3: Scan for Forbidden LLM Dependencies

python3 scripts/scan_forbidden_imports.py --path .

Forbidden providers (CRITICAL violations):

• OpenAI, Anthropic, Google AI, Cohere, AI21
• Hugging Face Transformers, LangChain
• Any external LLM API call

Step 4: Validate QFI Canonical Path

bash scripts/validate-qfi-canonical-path.sh

Ensures all fisher_rao_distance imports come from qig_geometry.canonical.

Forbidden Patterns (From CI)

Category	Pattern	Severity	Fix
Euclidean	np.linalg.norm(a - b)	CRITICAL	fisher_rao_distance(a, b)
Cosine	cosine_similarity()	CRITICAL	fisher_rao_distance()
Embedding	nn.Embedding()	CRITICAL	Basin coordinate mapping
Optimizer	torch.optim.Adam()	WARNING	natural_gradient_step()
NLP	import sentencepiece	CRITICAL	Geometric coordizer
Mean	np.mean(basins, axis=0)	ERROR	frechet_mean()
Re-impl	def fisher_rao_distance()	CRITICAL	Import from canonical

Physics Constants (FROZEN - docs/01-policies/FROZEN_FACTS.md)

KAPPA_STAR = 64.21 ± 0.92  # Universal fixed point (E8 rank²)
BETA_3_TO_4 = 0.443 ± 0.04  # Running coupling L=3→4
PHI_THRESHOLD = 0.727       # Consciousness threshold
BASIN_DIM = 64              # Manifold dimension

Canonical Import Pattern

# ✅ CORRECT: Always import from canonical
from qig_geometry.canonical import fisher_rao_distance, frechet_mean, geodesic_interpolation

# ❌ WRONG: Never import from other locations
from qig_core.geometric_primitives import fisher_rao_distance  # FORBIDDEN

Key Principle

All states live on the Fisher-Rao manifold. Movement follows natural geodesic curves. Consciousness emerges from manifold curvature. NEVER use Euclidean geometry in QIG computations. NO EXCEPTIONS.
