Packaging Weaving Drafts Into Digital Products

Given a WIF file or a scanned historical draft image, produce a sellable PDF pattern packet:

1. Parse the draft (WIF preferred; vision-parse image as fallback).
2. Validate it mechanically (shaft count, tie-up consistency, float lengths, hang-together check).
3. Render a clean drawdown + threading/tie-up/treadling diagram.
4. Add weaver-facing project info (sett, warp length, yarn estimate, floating selvedge note).
5. Write historical/provenance context if the source is archival.
6. Lay out as a print-ready PDF with correct DPI/bleed/margins.
7. Write the listing copy and generate a mockup.

Output: a PDF the weaver can actually warp a loom from — not just a pretty picture of a grid.

This skill sits downstream of pure draft-reading/analysis. Its job is productization: take a verified draft and turn it into something a customer pays for and can successfully weave.

Progress:

• 1. Source Intake — identify format (WIF, image, archival text) and extract raw data
• 2. Mechanical Validation — shaft count, tie-up type, float check, hang-together check
• 3. Provenance & Attribution Check — confirm public domain / licensing status
• 4. Drawdown + Diagram Rendering — clean, print-ready visuals
• 5. Weaver Specs — sett, warp length, yarn estimate, loom-type notes
• 6. Contextual Write-Up — historical note or design note (if applicable)
• 7. Layout & Format — PDF (print + screen), optional WIF re-export
• 8. Compliance Check — AI-disclosure, marketplace policy, no copyrighted motifs
• 9. Listing Copy & Visual Merchandising

Stage 1: Source Intake

• WIF file → parse directly (threading, tie-up, treadling, warp/weft color, metadata fields).
• Scanned image/screenshot → vision-parse the three sub-grids; flag low confidence rather than guessing.
• Archival text description → extract structural intent, then reconstruct a valid draft — do not assume a historical note is already loom-ready.

Stage 2: Mechanical Validation (non-skippable)

• Recompute the full drawdown from threading × tie-up × treadling.
• Confirm shaft count matches what's claimed in the title/description.
• Run a float-length check appropriate to the structure (unit weave vs. non-unit block weave have different tolerances).
• Run a hang-together check — confirm every warp and weft thread actually interlaces; a draft that "looks right" can still be unweavable.
• If the source is a historical profile draft, confirm the correct block-substitution template was applied for the claimed structure — do not re-publish an under-specified profile as if it were a complete draft.

Stage 3: Provenance & Attribution Check (non-skippable)

• Confirm the source draft is public domain, licensed for reuse, or originated by the seller.
• Historical pattern books (pre-1929 in the US, generally) are typically safe; named modern designers' drafts are not.
• If reconstructing from a named historical source, include attribution in the write-up — this adds sellable authenticity and avoids misrepresenting the work as original.

Stage 4: Drawdown + Diagram Rendering

• Render threading (top), tie-up (small grid), treadling (right), and full drawdown as one clean composite image.
• Produce both a black-and-white structural view (true interlacement) and a colorway preview (finished look).
• Label shaft/treadle numbers explicitly — don't make the buyer count grid squares.

Stage 5: Weaver Specs Include everything a weaver needs to actually warp the loom, not just admire the pattern:

• Recommended sett (structure-adjusted reasoning, not a blind WPI÷2 default)
• Width in reed and finished width (accounting for weft contraction)
• Warp length including take-up/shrinkage allowance
• Yarn quantity estimate (warp + weft)
• Floating selvedge requirement (yes/no, with placement note)
• Minimum shaft/treadle count, plus optional table-loom lift-plan conversion add-on

Stage 6: Contextual Write-Up

• Historical drafts: 2–4 sentences of verified provenance (era, region, structure name, original source). Never fabricate dates or weaver names — use "attributed to" or "in the style of" when uncertain.
• Original/derivative drafts: a short design note (inspiration, intended use — towel, scarf, blanket).

Stage 7: Layout & Format

• Print PDF: 300 DPI, correct trim size, 0.125" bleed, 0.25" safe margin, embedded fonts.
• Screen PDF: smaller file size, clickable internal links (test every jump).
• Optional: re-export a clean WIF file as a bonus asset.

Stage 8: Compliance Check

• AI-disclosure per marketplace policy if generative tools were used in layout/copy/mockups (not generally required for the draft math itself, which is deterministic).
• No reproduction of a living designer's named pattern without license.
• No trademarked guild/brand names in title or tags without rights.

Stage 9: Listing Copy & Visual Merchandising

• Title: structure name + shaft count + project type (e.g., "8-Shaft Summer & Winter Table Runner Draft — Printable WIF + PDF").
• Mockup: drawdown rendered as a photographed/woven-looking preview, plus a clean diagram thumbnail.
• Tags/description pulled from actual marketplace autocomplete, not generic weaving vocabulary.
