Question
What must load for the user and each tested consumer to observe the real content?
Nodes
URL; HTML; Script; Stylesheet; Image; Rendered state; Consumer observation
Relationship sketch
- page → required resource
- render observation → observed content
- consumer → access result
Evidence inputs
Initial responses, browser network captures, blocked-resource observations, versioned tests.
Implementation
Trace critical content, metadata, and links to dependencies. Test optional-script failure and record differences between browser and crawler observations; avoid pretending all consumers render identically.
Acceptance checks
- Essential content is observed under the agreed delivery contract
- Blocked resources have documented impact
- Actual crawler evidence is separated from a spoofed user-agent test
Do not infer
User-agent string selection does not authenticate a crawler or reproduce its complete behavior.
Publication boundary
Public assets; private traces redacted.
Source basis
S20, S27. See Research/sources.json. Sources support the primitives or named technology. The organization, labels, actions, and acceptance contracts in this catalog are this library's design, not claimed provider requirements.
