 ** notes
 - No recollection was needed; existing raw and collected exports were adapted in place and moved into the target names.
 - Updated the active script defaults to point at `data/...` so the code and on-disk layout now agree.
 - Kept obviously obsolete review artifacts, but moved them under `data/review/archive/` instead of deleting them outright.

 ** notes
+- Kept this explicitly Costco-specific and narrow: the cleanup removes known logistics/code artifacts and orphan slash tokens without introducing fuzzy naming logic.
+- The structured parsing still owns size/pack extraction, so name cleanup can safely strip dual-unit and logistics fragments after those fields are parsed.
+- Discount-line behavior remains unchanged; this task only cleaned normalized names and preserved the existing audit trail.
 
 * [ ] t1.15: refactor review/combine pipeline around normalized_item_id and catalog links (4-8 commits)
 replace the old observed/canonical workflow with a review-first pipeline that uses normalized_item_id as the retailer-level review unit and links it to catalog items
