+# Distro ingest (RareWaves first) + cost tracking + new/used — plan (2026-06-27)
+
+Buy stock from distros (RareWaves discount sales, ~$8–15 capped shipping → margin in volume), scrape the
+**order** + **wishlist** account pages via the PRICEGOD extension, land **cost price per copy** in inventory,
+and use the **wishlist** to gauge scarcity (how many stores / Discogs sellers stock it). Prep Rocket / Inertia /
+Bertus next (they send invoices to ingest).
+
+## ✅ Done (foundations, live on recordgod)
+- `inventory.cost_price numeric(10,2)` — per-COPY buy price (costs vary per copy, so inventory-level not release-level).
+- `inventory.cost_source text` — provenance, e.g. `rarewaves #592619`.
+- `inventory.condition_type text NOT NULL DEFAULT 'used'` — the **new/used binary split**. Backfilled: 451 sealed
+  items (`notes ILIKE '%seal%'`) → `new`; everything else `used`. (Distro-bought stock defaults `new`.)
+
+## What the RareWaves dumps revealed (analysis)
+RareWaves = **Shopify**. Source files on ultra `~/Documents/recordgod/rarw*.txt`.
+
+**Orders (rarworder*.txt)** — new Shopify customer-account React pages. Each line item:
+```
+<a href="/products/0603497816163-rumours-2025?variant=55398669779318">
+   <img alt="Rumours">   …   quantity 4   …   $42.99/ea
+```
+→ **barcode (EAN-13 = leading digits of the handle)** + **title (img alt)** + **year (in slug)** + **qty** +
+**unit cost (`$X.XX/ea`)** + variant id + order # (`Order #592619`). CSS classes are obfuscated hashes — key off
+the **`/products/<barcode>-` URL**, the **`/ea` price text**, ARIA `role="row"`, and `quantity N`. **High confidence.**
+
+**Wishlist (rarwwish*.txt)** — rendered by the **Klevu** app into collapsible `data-wishlist-row-id` rows. No clean
+barcode in the dump (the 13-digit hits were CDN cache-bust hashes `?v=…`, false positives). **Harder** — needs
+row→product mapping, likely via Klevu's data or by following each row's product link. Lower confidence; phase 2.
+
+## Build plan (sequenced)
+
+**1. Order scraper → cost into inventory (HIGH value, HIGH confidence — do first).**
+- PRICEGOD content script on `rarewaves.com/account/orders/*` (+ legacy `/orders/*`): walk each `role="row"`,
+  pull `{barcode, title, year(slug), qty, unit_cost, variant_id}` + the order number.
+- New RecordGod endpoint `POST /admin/intake/distro` `{source:'rarewaves', order_ref, items:[…]}` → per item:
+  resolve **barcode → release_id** (local `disc_release_identifier` `type='Barcode'`, **normalised**: strip
+  non-digits, try with/without leading 0; Discogs `/database/search?barcode=` fallback), enrich, **stage** with
+  `cost_price=unit_cost`, `cost_source='rarewaves #<order>'`, `condition_type='new'`, one SKU per copy (qty → N rows).
+- Reuses the existing `_stage`/`_enrich` + the staged review queue. Token = the RecordGod store token already minted.
+
+**2. New-stock approval landing (staff confirm release_id before commit).**
+- A `/admin` "New stock" review view over `staged` rows that came from distro ingest: shows the scraped title +
+  barcode + auto-resolved release_id (with cover) + the cost; staff **confirm or re-pick** the release, set
+  retail price, then **publish** (staged→live). Resolve heuristics John named: almost always **reissues → newest
+  year**; assume **black vinyl** unless the slug/title says coloured; barcode pins it when present.
+
+**3. New/used in the inventory UI.** Add `condition_type` (new/used toggle) + `cost_price` to the inventory
+edit form + show on the list; surface **margin** (price − cost) where both exist.
+
+**4. Wishlist scarcity (phase 2, speculative).** Map wishlist rows → release_id, then count **how many stores /
+Discogs sellers** stock each (DealGod has the cross-store + Discogs-seller data; reach via its API). Shows relative
+scarcity to prioritise buys. Needs the Klevu row→product decode first.
+
+**5. Other distros (Rocket / Inertia / Bertus).** They send **invoices** (PDF/CSV) not web pages → an invoice
+ingest (upload → parse line items → same `/admin/intake/distro` core). Generic `source` + `cost_source` already
+support it. Likely an LLM/parse step per invoice format.
+
+## Open questions for John
+- Order URL pattern: is it `rarewaves.com/account/orders/<id>` (new accounts) — confirm so the content-script match is right.
+- Retail price on distro stock: auto-suggest from DealGod median, or staff set per item at approval?
+- Wishlist scarcity: worth the Klevu-decode effort now, or park until orders+cost are proven in daily use?
