Overview

Resolves, for each flat-search hit that is only reachable through a linked creative shell, the path of node ids to expand *in the signed-in user’s own tree* to surface that shell — ordered root-most ancestor down to the shell itself.

Why this exists: search breadcrumbs (BreadcrumbResolver) carry the hit’s origin-space ancestors. When a shared subtree is represented by a shell nested under one of the user’s own folders, those origin ancestors never include the local folder that contains the shell, so the picker’s breadcrumb-jump cannot expand down to it (the shell <li> is never rendered and ‘_findItem` returns null). This service supplies the missing user-local prefix `[localFolder…, shellId]`; the client expands it before walking the origin chain. Display is unaffected — only navigation.

Returns { hit_id (Integer) => { origin_ancestor_id (Integer) => [user_tree_id, …] } }, i.e. for each hit, a per-origin-ancestor map: every origin ancestor (incl. the hit itself) that the user holds a renderable shell for maps to the local path that surfaces that shell. The client anchors a breadcrumb click at the entry at/above the clicked crumb, so a higher ancestor crumb resolves through its own shell rather than a deeper one (a user may hold shells at several depths of the same shared subtree). Hits not routed through any shell are omitted (their origin path already matches rendered ids).
