An unpinned model version is a silent regression channel
Model drift, configuration drift and cost drift all show up quietly, until someone asks why. Here is how we pin, roll back and keep spend visible before that happens.
Notes from delivery. Patterns we keep reusing and mistakes we'd rather you didn't repeat.

Governance, environment, identity and guardrails have to be proven before the first non-engineer ships an internal app — not layered on after it already shipped.
Handover isn't documentation plus a call. It's access narrowed, our own access removed, and a runbook proven against failures that actually happened — not ones we imagined.
Unit tests, data invariants, business prompts and a faithfulness check each catch a different failure — and a demo can pass every one of them while a real question still breaks it.
Write-back is where the risk is, and it is also where most of the value isn't. Start with an agent that tells people what to look at.
Source system to BigQuery, curated views, MCP Toolbox on Cloud Run, an agent runtime with no database access of its own. Here is why each piece is there.
It is not the AI. Across six rollouts this year, the schedule risk lived in identity, connector allowlisting and naming confusion.
Tell us what system the answer lives in and who needs it. We'll reply with a view on whether it's a two-week assessment, a five-week pilot, or something else.
