Vector graphs that respect schematic hierarchy

Schematics punish naive chunking: a caption on page six might govern a symbol on page one. We model diagrams as small graphs and feed the retriever with explicit parent-child hints instead of flat windows.

Practitioners in our Retrieval design studio cohort tested three rerankers. The winning approach penalized candidates that crossed voltage domain boundaries unless the question explicitly asked for cross-domain analogies.

Latency budgets forced compromises. We document which edges were collapsed for speed and where human reviewers must reopen the graph. That honesty keeps field engineers trusting the assistant during outages.

Finally, we archive failed retrievals as synthetic negatives for the next fine-tune without drift sprint. The loop is slow, but it respects the safety bar set by industry advisors in regulated environments.
