Bank 4 batch 3: the Shipping AI interfaces course lands
Fifteen essays (91 → 106) form a complete curriculum in one series: anatomy of an AI answer, honest streaming, thinking states, the composer as a form, trustworthy model pickers, token budgets, citations, retry and rate limits, agent steps, disclaimers, local-first as a feature, the temperature dial, honest feedback, model comparison without benchmarks, and a closing ten-question checklist. Every essay links the bank-4 components and prompts it teaches, and each one carries the series rail, takeaways and a glossary cross-link (docs/enrichment-bank4.md).

This entry predates the build report, so it carries no size figure. Saying so is the point: a changelog that quietly omits its numbers reads as if every change were free.
