Editorial policy / A living curriculum
Broad topics. Clear evidence.
A learning library should preserve useful depth while correcting mistakes. Here is how sources, execution limits and older lesson addresses are treated.
What belongs in the library
Public routes use the current published catalog. Retired material is not presented as an active lesson, and a historical schedule is not evidence that every lesson in that schedule remains available.
What an editorial review means
An editorial review checks the lesson’s explanation and consequential claims against named sources, repairs identified errors and records the limits of its tests. Passing compilation or finding a citation URL is not factual validation. The label is not peer-review certification, a promise of production readiness, or proof that every example has been executed in your environment.
Conceptual cloud and distributed-systems lessons can be supported by official documentation without claiming a deployment was reproduced. Local numerical checks are not GPU-training results, benchmarks or independent proof verification. Read each lesson’s sources, assumptions, exercises and execution boundaries.
What happens to an old link
A useful lesson whose substantive review is unfinished shows an explicit under-review notice. It is not silently classified as bad material, included in the published learning sequence or given a reviewed label. A removed lesson shows a retirement note when a migration record is available. A consolidated lesson redirects only when its learning objectives are covered by the published replacement. Useful topics are not retired merely because they are advanced or a cloud environment was not executed. Unrelated lessons are never substituted just to keep a link alive.
What “next” means
Lesson progression follows a learning path, not publication time. If there is no next lesson in the published path, the interface returns you to the library rather than pretending an unrelated article is the next step.
October 2026 · A different kind of lab
A new learning map, searchable library, inline gradient experiment and device-local notebook replace the old feed-first experience. The current catalog, rather than an old advertised total, determines every lesson count.
