Ducklake Pattern Expansion Skill

Ducklake Pattern Expansion

Version: 1.0.0 Status: Production Ready Created: 2025-12-21 High Confidence Core: 153 mentions

Overview

Loads pattern discovery from Subagent 3 and provides progressive wave-based expansion for discovering related patterns, computing world reachability, and exploring possibility space.

Purpose

Enable progressive pattern discovery through 3 expansion waves:

Wave 1: Direct matches (high confidence ≥0.95)
Wave 2: Relational discovery (medium confidence ≥0.75)
Wave 3: Structural analysis (exploration confidence ≥0.50)

Data Sources

Primary: /Users/bob/ies/SUBAGENT_3_PATTERN_DISCOVERY.json (if exists)
Fallback: Meta-cognitive synthesis JSON
Schema: VERS_DUCKLAKE_SCHEMA.sql (48 agents, 16 repos)

Functions

expand_wave1(patterns: list[str]) -> dict

Direct pattern matching with high confidence.

results = expand_wave1(["ducklake", "temporal", "versioning"])
# Returns: {
#   "temporal_duckdb": {"confidence": 0.95, "mentions": 47},
#   "versioning_crdt": {"confidence": 0.92, "mentions": 31},
#   "ducklake_core": {"confidence": 0.97, "mentions": 153}

    base_path = Path("/Users/bob/ies")

    for pattern in patterns:
        matches = []
        confidence_sum = 0

        # Search all relevant files
        for file_path in base_path.rglob("*"):
            if file_path.is_file():
                try:
                    content = file_path.read_text()
                    count = len(re.findall(pattern, content, re.IGNORECASE))
                    if count > 0:
                        matches.append({
                            "file": str(file_path),
                            "count": count
                        })
                        confidence_sum += min(count / 10.0, 1.0)
                except:
                    continue

        if matches:
            avg_confidence = min(confidence_sum / len(matches), 1.0)
            if avg_confidence >= 0.95:
                total_mentions = sum(m["count"] for m in matches)
                results[f"{pattern}_core"] = {
                    "confidence": round(avg_confidence, 2),
                    "mentions": total_mentions,
                    "files": len(matches)

from skills.ducklake_pattern_expansion import *

print("=== WAVE 1: Direct Matches ===")
wave1 = expand_wave1(seed_patterns)
for pattern, data in wave1.items():
    print(f"{pattern}: {data['mentions']} mentions ({data['confidence']:.0%} confidence)")

print("\n=== WAVE 2: Relational Discovery ===")
wave2 = expand_wave2(seed_patterns)
for pattern, data in wave2.items():
    print(f"{pattern}: related to {', '.join(data['related'])}")

print("\n=== WAVE 3: Structural Analysis ===")
wave3 = expand_wave3(seed_patterns)
if "48_agent_topology" in wave3:
    topo = wave3["48_agent_topology"]
    print(f"Found {topo['structure']} with {topo['agents']} agents")

# World reachability
print("\n=== World Reachability ===")
path = compute_world_reachability(
    "world_hopping_duckdb_analysis",
    "ies_augmentation_cognitive_superposition"
)
if path["via_intermediate"]["feasible"]:
    print(f"Path: {' → '.join(path['via_intermediate']['path'])}")
    print(f"Distance: {path['via_intermediate']['distance']:.2f}")
    for event in path["via_intermediate"]["events"]:

Expansion Frontiers

Immediate (Distance < 2.0)

Temporal versioning enhancement
Color stream branching
Session evolution tracking

Medium-Term (Distance 2.0-3.5)

DuckLake federation (NATS/Synadia)
Skill-based query language (SDQL)

Triangle Inequality Constraints

For worlds W1, W2, W3:

d(W1, W3) ≤ d(W1, W2) + d(W2, W3)

Example:

d(temporal, cognitive) = 5.49
d(temporal, structural) + d(structural, cognitive) = 2.87 + 3.14 = 6.01
Constraint satisfied: 5.49 ≤ 6.01 ✓

GF(3) Distribution

This skill operates across all three categories with balanced emphasis:

Wave 1: YELLOW (GF3=1) - Structural pattern matching
Wave 2: RED (GF3=0) - Temporal relationship discovery
Wave 3: BLUE (GF3=2) - Cognitive possibility exploration

Skill Type: Pattern Discovery Color: MULTI (triadic) Polarity: GF(3) = 0 (balanced) Access Pattern: Progressive expansion
