#reconcile_scopes ⇒ Object

Bounded reconcile scope roots for this entry, one per region × color.

The sweep root is the parent directory of the entry's rendered output_directory, derived from the actual directory: pattern rather than assuming a fixed layout. For a .../<service> pattern that parent is the <region>/<cluster_type>/<color> base; for a <region>/<service> pattern it is <region>. The parent is shared with sibling entries, so leftovers from a deleted/renamed entry under it are swept. The renderer validates each base_root stays within rendered_directory (out-of-prefix, full or relative, is a hard error).

Each scope also carries spp: (whether this entry is an SPP definition) and spp_base_root: (the canonical <region>/<cluster_type>/<color>/spp/SPP-PLACEHOLDER prefix for that region × color) so the renderer can enforce the SPP layout guard before rendering.
