The defenses you haven't built yet — async, a path traversal, and the bug erasing the evidence
A Monday that converted the whole RAG pipeline from sync to async (fast search 9 seconds to under 150 milliseconds), then watched the platform's own automation find a path traversal in its own code — bracketed by the discovery that an upstream auto-update bug had quietly deleted two months of the evidence this series is written from.

The Second Graph Comes Online: Activation, Communities, and an AI Reversal
How the second knowledge graph went from intermittent to dependable — Python AST plus FalkorDB plus Leiden community detection — and the moment the Kafka consumer pattern from the journal pipeline generalised into a fleet of code-intelligence workers. With one deliberate reversal from LLM-based to deterministic NLP that cut hallucinated tags from 75% to 0.3%.
