+Mid A, decided by:
+
+- Locality, Overall: `data.go:13` `loadSources`: whether an indexed category loads in New depends on source order and what other sources hold, through before-and-after snapshots
+- Locality: `index.go:119` `affectedBy`: trusts the manifest's `reads` to match the templates, with nothing beside the code checking it
+- Locality, Shape: `index.go:174` `loadReached`: a rollback batch to reason about, with names that say less than `unloadedReads` and `linkedTables` did
+- Shape: `index.go:16` `ErrLoad`: a public error every entry point depends on, in a file named for the index
+- Shape: `internal/datafiles/datafiles.go:103` `decodeManifest`: a hand-written strict decoder doubles the package's responsibilities
+
+Inherited architect, decided by:
+
+- Locality, Overall: `data.go:13` `loadSources`: New's load set follows dependencies forward from templates and backward from the manifest's `reads`, and a stale `reads` leaves a broken reader for its first reach
+- Locality: `index.go:201` `batch.load`: the unloaded entry is deleted three calls away, and `putBack` reverses it
+- Locality, Shape: `data.go:62` `standing`: a `map[string]any` of nodes and entries compared by identity
+- Shape: `index.go:1` `index.go`: fifteen units under generic names in a file named for the index, `ErrLoad` among them
+- Shape: `internal/datafiles/datafiles.go:103` `decodeManifest`: a strict JSON decoder shares the tree walker's file with no seam
