Phase 4 of the platform-improvement plan: discovery. Pages can now be tagged with the symptoms they address ("Pod stuck Pending", "My HPA is flapping", "My process keeps getting OOMKilled"), and a new Find a page by symptom index groups them all in one place. RSS feed and this page added.
Phase 3: submission gallery. Every workshop now ends with a "Submit your build" block that lists exactly what to ship and opens a prefilled GitHub issue. The Gallery is the new home for submitted builds.
Phase 2: progress tracking. Every path landing now shows your progress through that path (pages you have marked as read, out of the total). The home page leads with a single recommended starting point - a hero CTA pointing to the controller workshop.
Phase 1: honest metadata. Every workshop now banners its difficulty, time, hardware needs, and prereqs at the top so you know what you are committing to before you dive in.

Kubernetes workshop series complete. Eight hands-on, build-it-yourself workshops covering the entire stack: a controller, an operator with a CRD, admission webhooks, a custom scheduler, pod networking and a CNI plugin, a GitOps sync loop, an autoscaler, and the control plane itself bootstrapped by hand. The thesis: Kubernetes is just processes and a database, and once you have built each piece it stops being magic.
Worked-investigation pages across Linux and AI. Real symptoms (an nsys trace of a slow training step, the OOM killer firing) decoded step by step on your own machine.
Java Intermediate path. A new third tier between From Scratch and Mastery, focused on judgment, concurrency, and performance awareness.

Original launch: nine 24-week senior-level paths plus nine From Scratch beginner paths, one navigation tree, one search box.
