F2: tick table (SKU green via the code match incl. AI fills, grey per tick,
pairing failure -> all grey, different product -> red), stock lines use the
line SKU, Add to POS needs a SKU, SKU fills audited for order lines only.
F3: content_hash is a non-unique index (identical uploads share a hash,
skipped PDFs have an empty hash) - matches the migration.
