Domain Knowledge

Three references, with different jobs:

• references/rubric.md is the scoring source: severity definitions, 1-10 anchors per dimension, where a finding belongs, the N/A rule, and the overall-score computation. Read it first; it is short. Using it keeps scores repeatable across runs.
• references/checklist.md is what to look for during the analysis steps, section by section.
• references/wisdom.md is optional background, auto-generated from the blog posts below. It has no rubric. Grep it by heading for a specific question (for example "percentiles" or "stampede"); never read it whole, it is about 86 KB.
