Stop Asking the Model What the Categories Are

We rebuilt issue clustering by moving the taxonomy out of clustering entirely — into detection. What broke in the first version, what the rewrite bought, and what it cost.

The Multiplicative Failure Trap: Why Multi-Tool AI Agents Crash Midway

Why multi-tool AI agents scraping websites, inboxes, and SaaS tools keep failing midway, and how state checkpointing stabilizes multi-step workflows.

ClickHouse Text Indexes, Direct Read, and the Compatibility Trap

We shipped a text index that did byte-for-byte nothing while every diagnostic said it was working. The culprit: one compatibility setting silently pinning a prerequisite off.

The Granularity Problem, or: Why Your Embeddings Don't Know What a "Third-Party Integration" Is

Two VPs want the same dashboard at different zoom levels. Why dendrogram cuts can't give it to them — and what to build instead: leaf dedup, extracted facets, and a declared taxonomy.
