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.
