 ### Changed
 
+- Fresh bootstrap now creates only minimal system records; operational domains no longer start with seeded demo customers, vendors, inventory, BOMs, or warehouses
 - Sales and purchasing detail pages now expose revision comparison directly alongside chronological revision history
 - `ROADMAP.md` now tracks remaining work only, and shipped phase history now lives in `SHIPPED.md`
 - Support logs now prune retained entries by age instead of only trimming by count, and admin diagnostics now reviews filtered support-log summaries instead of an unbounded flat dump

 - reserved and available quantity visibility by location
 - item-level file attachments for drawings and support documents

-- seeded sample warehouse and stock locations during bootstrap
+- fresh bootstrap starts inventory and warehouse data empty so first-run environments do not include demo operational records
