Overview

In-memory index of partials (‘_.`) under the view root.

## Key normalization The path relative to the view root is normalized to “directory + basename without the leading underscore”. All qualifiers that follow the partial name (format, handler, locale, variant) are dropped.

app/views/admin/areas/_form.html.erb        -> "admin/areas/form"
app/views/admin/areas/_form.en.html.erb     -> "admin/areas/form" (locale variant shares the key)
app/views/admin/areas/_form.html+phone.erb  -> "admin/areas/form" (variant shares the key)

Since multiple formats can map to the same key, the value is always an array of file paths.

The index is updated incrementally via file-watching events rather than re-globbing on every request (performance requirement).
