Verify First: a catalogue of what verification cannot see

Field notes

The page organizes verification around both actions taken and symptoms observed, then links each situation to numbered entries in an NS registry. Examples include distinguishing a running process from a functioning service, checking whether a test actually exercised a feature, and testing whether a successful HTTP response contains the right data. The homepage identifies the reference as version 7.2.0 with 90 entries spanning six instruments, and exposes links for its registry, protocol, MCP, limits, and GitHub materials.
