Give the Buy column a real distributor link   (Mouser first, then DigiKey/LCSC), or the Adom stock page for a Basic Part. - Projects without reference designators (a symbol library, a cabinet layout) keep the icon cell-  and drop Qty/Refs: `| Part | Library symbol | Role | Buy |`.+  and drop Qty/Refs: `| Part | Library symbol | Role | Unit cost | Buy |`. - Verify on the rendered page in pup: every icon loads (`img.naturalWidth > 0`) and every link opens   logged out when the page is public. +### Part cost is required, not optional++Every project README component table MUST include a **Unit cost** column and, when+quantity is known, a **Line cost** column. A Buy link alone is not cost information.+This applies to electrical parts, connectors, housings, crimps, wires, fans,+heatsinks, mounting hardware and custom parts. Put the major functional parts first,+then connectors/mechanics, with resistors and capacitors lower in the table.++- Show currency and per-piece price, with the supplier price-break quantity and date+  checked. Example format only: `USD 1.25 each (buy 10+, checked YYYY-MM-DD)`.+  Link the price to its actual supplier listing or quote, preferably using Buy.+- Use the quantity needed for one assembly for Line cost (Qty × applicable unit+  price). State the planned build quantity that determines the price break.+  Distinguish consumed BOM cost from minimum-order, pack/reel and spare purchase+  outlay; do not imply a ten-piece price is available when buying one piece.+- Never invent a price or use zero for an unknown. Write `Unknown (not checked)`,+  `Quote required`, or `Estimate: ...` with its basis. Mark old prices with their+  original check date; do not relabel them as current without rechecking.+- Stocked parts still have a cost: use a documented inventory/replacement cost,+  or mark it unknown. For wire/consumables state the length or unit basis; for+  machined/printed parts separate material and fabrication allowances when known.+- Below the table give the known per-assembly subtotal and list unpriced items.+  Never call a partial subtotal the complete BOM total. State whether tax, shipping,+  PCB fabrication, assembly and tooling are excluded. Preserve source currency;+  document the date/rate for any currency conversion.+- Before publishing, verify every row has cost information or an explicit unknown,+  quantities and arithmetic agree, and source/date/break assumptions are visible.+  Inspect the rendered table for readability. A numeric total is not a supplier quote.+ ## Open-source pages need a "check it out, vibe-code it, send it back" section  If the page's source is public (open source), the README MUST teach the
