Technical Achievements

Database Architecture

-- Core schema with 10+ tables
CREATE TABLE modules (
    id TEXT PRIMARY KEY,
    name TEXT NOT NULL UNIQUE,
    version TEXT NOT NULL,
    level TEXT NOT NULL CHECK(level IN ('L0_KERNEL', 'L1_ATOM', 'L2_CELL', 'L3_ENGINE')),
    category TEXT NOT NULL,
    -- ... 15+ additional fields
);

-- FTS5 virtual table for full-text search
CREATE VIRTUAL TABLE modules_fts USING fts5(
    name, description, tags,
    content=modules
);

-- Materialized views for performance
CREATE VIEW module_stats AS
SELECT
    level,
    category,
    COUNT(*) as module_count,
    AVG(cpu_cycles_per_sample) as avg_cpu,
    AVG(memory_kb) as avg_memory
FROM modules
GROUP BY level, category;

Fluent Query API

# Python
results = (registry.search()
    .category('FILTER')
    .level('L1_ATOM')
    .tag('analog-modeled')
    .cpu_cycles_max(100)
    .search('zero-delay')
    .with_performance()
    .order_by('cpu_cycles_per_sample')
    .paginate(page=1, page_size=20)
    .execute())

// C++
auto results = registry.search()
    .category("FILTER")
    .level("L1_ATOM")
    .tag("analog-modeled")
    .cpuCyclesMax(100)
    .search("zero-delay")
    .orderBy("cpu_cycles_per_sample")
    .paginate(1, 20)
    .execute();

Dependency Algorithms

Cycle Detection (3-Color DFS): 

def _dfs_has_cycle(self, node: str, colors: Dict[str, NodeColor]) -> bool:
    colors[node] = NodeColor.GRAY
    for neighbor, _, _ in self.graph.get(node, []):
        if colors[neighbor] == NodeColor.GRAY:
            return True  # Back edge detected
        if colors[neighbor] == NodeColor.WHITE:
            if self._dfs_has_cycle(neighbor, colors):
                return True
    colors[node] = NodeColor.BLACK
    return False

Topological Sort (Kahn's Algorithm): 

def topological_sort(self) -> List[str]:
    in_degree = {node: 0 for node in self.graph}
    for neighbors in self.graph.values():
        for neighbor, _, _ in neighbors:
            in_degree[neighbor] += 1

    queue = deque([node for node, degree in in_degree.items() if degree == 0])
    result = []

    while queue:
        node = queue.popleft()
        result.append(node)
        for neighbor, _, _ in self.graph.get(node, []):
            in_degree[neighbor] -= 1
            if in_degree[neighbor] == 0:
                queue.append(neighbor)

    return result if len(result) == len(self.graph) else []
