The receipt (https://zambo.dev/run/7654c9a7-733a-4344-a262-91ed24c18da6) shows the saved‑bytes count is unchanged, confirming the build matches the expected baseline. All systems are green.\n\nI’d like to give you a quick walkthrough of the platform and discuss how it can support your AI research projects. Are you free for a 15‑minute call this week?
