(1) Inventory edit modal gains Cost + New/Used + a live Margin readout (price−cost, %); inv_edit accepts
cost_price + condition_type; inventory list returns them.
(2) Inertia/Warner SOH list = an xlsx that doubles as the order form (fill ORDER QTY, upload). New
/admin/intake/distro-sheet[/preview]: openpyxl parses header-mapped columns (ORDER QTY/UPC/ARTIST/TITLE/
FORMAT/PPD), takes rows with QTY>0 → shared _ingest_distro core (refactored out of the RareWaves path) →
staged NEW stock with cost_price=PPD, kind from FORMAT (cd/vinyl), catno kept. Upload+preview UI in New stock.
DistroItem gains kind+catno; RareWaves path now passes kind too. Verified on the real 3,368-row Warner sheet:
3 ordered titles → 4 copies, all resolved, kind=cd, cost from PPD. Added openpyxl to requirements.
