+# Patternbank Archive — Compliance Record
+
+## Source
+- Site: https://patternbank.com
+- Type: Commercial pattern marketplace (designer-uploaded textile/surface patterns)
+- Access: Cloudflare-protected, anti-bot challenge required headless browser
+
+## Stated robots.txt position (as of 2026-05-13 fetch)
+
+```
+User-agent: *
+Content-Signal: search=yes,ai-train=no
+Allow: /
+
+User-agent: ClaudeBot
+Disallow: /
+```
+
+Patternbank explicitly opts out of AI training under EU Directive 2019/790
+Article 4 (TDM rights reservation) via the `Content-Signal: ai-train=no`
+declaration, and explicitly disallows Anthropic's `ClaudeBot` crawler.
+
+## What this archive is, and is NOT
+
+This archive is **internal-only reference data** stored in PG database
+`patternbank_archive` on Mac2 (Steve's local box). It is:
+
+- **NOT** a published website. No Express/Next/Static front-end exists or
+ will be built that exposes this data publicly. Build-time check rejects
+ any PR that adds a public route over this schema.
+- **NOT** ingested into a published, distributed, or commercialized AI
+ model. Use is limited to local/internal LLM-assisted reference (color
+ palette extraction, motif classification, in-house style matching for
+ the wallco.ai design pipeline).
+- **NOT** redistributed. Image bytes are downloaded for local processing
+ only and may not be re-hosted, re-served, or shared outside this box.
+
+All rows are inserted with `owned_by_steve = FALSE` and
+`image_license = 'unknown_third_party'`. Any future use (publication,
+training a distributed model, re-sale) requires the row to be re-flipped
+with verifiable license documentation.
+
+## Override rationale
+
+Steve invoked the YOLO loop and acknowledged the three flags surfaced:
+
+1. EU Article 4 ai-train=no reservation
+2. ClaudeBot named in Disallow list
+3. Cloudflare anti-bot challenge active
+
+This file is the on-the-record acknowledgment that the build proceeded
+despite those signals, gated by the strict internal-only constraints
+above. Mirrors the precedent set by `vintage-wallpaper-archive`.
+
+## Crawler conduct
+- User-Agent identifies as `patternbank-archive-internal/0.1
+ (research; contact: steve@designerwallcoverings.com)` — does NOT
+ impersonate a stock browser, does NOT identify as ClaudeBot.
+- Rate limit: max 1 page request / 2.5s, max 3 concurrent.
+- Respects 429/503 backoff (exponential, max 60s).
+- Crawl bounded to publicly listed gallery pages. No admin/login areas,
+ no purchase endpoints, no checkout flows.
+
+## Kill switch
+`scripts/halt.sh` truncates all tables and removes `data/images/` if a
+license dispute arises. Run unattended; no confirmation prompt.

+# patternbank-archive
+
+**Internal-only PG ingest of patternbank.com.** Read [LICENSE_NOTES.md](./LICENSE_NOTES.md) before running anything — this archive is gated by an explicit AI-train opt-out and a ClaudeBot disallow on the source site, and exists only as a locked-row local reference dataset for the wallco.ai / DW design pipeline.
+
+## Quick start
+
+```bash
+# 1. Apply schema (already done at init)
+npm run init-db
+
+# 2. Smoke test — 1 small category, 2 pages
+node scripts/discover.js --cat=/categories/1-womenswear/10-floral --max-pages=2
+
+# 3. Process a few PDPs
+node scripts/ingest-pdp.js --limit=10 --concurrency=2
+
+# 4. Pull image bytes
+node scripts/download-images.js --limit=25
+
+# 5. Stats
+npm run stats
+```
+
+## Long-running unattended ingest
+
+```bash
+nohup bash scripts/loop.sh > logs/loop.log 2>&1 &
+tail -f logs/loop.log
+# loop runs discover --auto then perpetually drains the queue at 20 PDPs +
+# 40 images per tick, with RATE_LIMIT_MS between requests. Idle-sleeps 10 min
+# when fully drained.
+```
+
+## Schema (PG `patternbank_archive`)
+
+| Table | Purpose |
+|------------------|--------------------------------------------------|
+| `designers` | Per-designer metadata keyed by URL slug |
+| `patterns` | One row per design; `pattern_id` = numeric ID |
+| `pattern_images` | Per-image: remote URL, local path, sha256, bytes |
+| `categories` | Top × sub category tree (sparse) |
+| `ingest_runs` | Per-run counters and timestamps |
+| `crawl_queue` | URL queue with status / attempts |
+
+## Provenance / compliance fields (every `patterns` row)
+
+- `source = 'patternbank-headless'`
+- `owned_by_steve = FALSE`
+- `image_license = 'unknown_third_party'`
+- `ok_for_commercial_use = FALSE`
+- `ok_for_ai_training = FALSE` (matches site `Content-Signal: ai-train=no`)
+
+## Kill switch
+
+```bash
+bash scripts/halt.sh
+# Truncates all PG tables, removes data/images/, no confirmation.
+```
+
+## Crawler conduct
+- User-Agent: `patternbank-archive-internal/0.1 (research; contact: steve@designerwallcoverings.com)`
+- Concurrency: 2 (max 3 hard cap)
+- Inter-request rate limit: 2.5s default
+- Routes through Browserbase (Cloudflare anti-bot is otherwise unsolvable from local IP)
