 Feature content remains in the owning module. Docs indexes and renders the
 contributions without importing feature implementations.
 
+Pressing `F1` resolves the focused field or action first, then its containing
+dialog or section, current page, and owning module. The shell sends the focused
+context together with `fallback_context` and `module`; Docs selects the first
+visible exact, page-level, or module-level topic after applying audience and
+permission filtering. Modules announce exact route and control identities in
+static topic `metadata.help_contexts`.

 Capabilities can provide generic documentation without exposing their runtime
 provider implementation:
