How the tracks connect
Start anywhere your pain is sharpest—then follow cross-links. If retrieval quality drops, you will touch retrieval theme and measurement. If a model swap breaks tone, you will touch prompts and evaluation hub. For curated orders, see reading paths.
What you can skip (and what you cannot)
You can read essays in any order if you already know where your bottleneck is. You should not skip defining contracts and risk tiers before scaling traffic—otherwise “green” releases hide silent regressions in high-stakes surfaces. The topic map lists six cross-cutting themes that appear in every long read.
Where these tracks sit in the stack
Prompts define interfaces; retrieval supplies evidence; evaluation proves you still meet promises after change. Six theme hubs—measurement through operations—describe concerns that cut across all three. The lifecycle strip on the home page shows a coarse ordering from defining behavior through operating in production.
