What the Ledger says
Sidero builds toward a full data-centre stack on one immutable OS, adding a hypervisor, Director and an AI platform after Yardi bought it in September 2026. The record is a Talos minor every four to five months within days of Kubernetes, steady security hardening and few dated promises; three new products are one month old. A buyer gets a lean, strict OS and fast Kubernetes uptake, but accepts one OS, a nine-month support window and Omni under a source-available licence.
AI say-do: 2 announced (Cupar, Talos Linux for AI), 0 GA, 2 preview or undated, 0 pending beyond them, 0 dropped; the real AI work is GPU driver and operator support, with a commercial AI platform one month old.
