What the implementation taught me.
Short notes, not inflated essays. Observations about retrieval, failure paths, and the interfaces around them.
Why vector retrieval alone was insufficient
Semantic similarity finds nearby language. It does not automatically preserve prerequisites, hierarchy, or evidence chains.
Designing document-processing state machines
A pipeline is easier to trust when every transition has an owner, an invariant, and a cleanup path.
Why successful demos still fail in production
The happy path demonstrates possibility. Production is the accumulation of unusual inputs, interrupted requests, and ambiguous ownership.
Optimistic UI beyond perceived speed
Optimism is a temporary claim the interface makes. Good product engineering defines how that claim can be corrected.
