 - **Round-1 outputs are sacred.** Generators emit one shot per prompt. Don't retry-until-clean — feed defects through `scripts/fix-design.js` / `fix-seam.py` / `fix-frame-overlay.js` to preserve composition. Re-rolling discards the artist intent. See `~/.claude/skills/fix-design/` for the fixer playbook.
 - **Solid screen-print colors only.** No gradients, no transparency, no ghost layers unless the prompt explicitly asks for them. Anti-prompt enforcement in `scripts/generate_designs.js` plus a Gemini vision pre-publish gate.
+- **Always paint on a REAL natural wallcovering texture.** When generating a pattern, the ground MUST be anchored to an actual DW natural-material SKU — **grasscloth, cork, raffia, mica, real linen, silk, sisal, abaca, seagrass, jute, hemp, arrowroot, paperweave, bamboo, reed** — never a flat/hallucinated "ivory paper" ground. The motif is painted *on top of the real textile* so the weave/slubs/flecks show through. Mechanism: `scripts/gen-luxe.js` `pickTextureBrief()` pulls a random real SKU from `shopify_products` (matched by material regex) and injects `Ground: <family> <material> (matched DW SKU <name>, dominant #hex)` into the prompt; the snapshot namer then reads that ground hex for the colorway (`refresh_designs_snapshot.py` `ground_hex()`). DW has real SKUs for all of these (mica 292, cork 384, raffia 381, grasscloth 1978, linen 1857, silk 1478, +2862 other-natural). If you add a new generator, copy this real-texture-anchor pattern — a flat paper ground is a regression.
 - **Settlement gate before publish.** `~/.claude/skills/settlement/` orchestrates 5 detectors (a1 directional leaves, a2 open space, a3 multiple colors, b prohibited elements, acceptable elements) + verdict combinator. Never set `is_published=true` without the gate returning `OK`.
 - **TIFs are full-size archives.** Every design has a `tif_path` (150 dpi, up to 36000 × 19800 px, ~2 GB). The publish gate refuses NULL `tif_path`. Thumbs online, real file must exist.
 - **No vendor names in public UI.** 30-vendor denylist enforced in PG bulk rename + server.js dropdown filter. `wallco.ai/library` is admin-only.
