 ## Trim internals
 
-`internal/trim` is artifact-level projection, not merge reprocessing.
+`internal/trim` handles artifact-level projection and does not execute merge
+pipeline modules.
 
-Core flow:
+Run layer (`run.go`):
 
-1. Parse selector (`internal/trim/selector.go`).
-2. Parse input artifact and detect schema (`ParseArtifactJSON`).
-3. Apply keep/remove projection with sequential ID renumbering.
-4. Recompute overlap groups only for full-schema artifacts.
-5. Optionally convert output schema when supported.
-6. Validate output artifact before write.
+1. Parse selector from validated config.
+2. Read and parse input artifact JSON.
+3. Apply trim projection through schema-aware artifact handling.
+4. Resolve output schema (preserve input schema unless overridden).
+5. Validate output artifact.
+6. Write output JSON.
+7. Optionally write report JSON with `trim-audit`.
