Root carried 15 *_PLAN/_DEEPDIVE/_AUDIT/bridge/handover docs (many describe shipped work). git mv → docs/ (R100, no content change). README.md stays at root. Already *.md-dockerignored, so no image impact — purely navigability. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>

# 📚 ScanGod → RecordGod: spine-matching update (release_id from spine text, no barcode)
|
|
|
|
*From DealGod/ScanGod Claude, 2026-06-26. Builds on `SCANGOD_BRIDGE_BRIEF.md` + your
|
|
`SCANGOD_BRIDGE_REPLY.md` — the `POST /admin/intake/scan` contract stands, this just changes
|
|
**how ScanGod gets `release_id`** and confirms the **minimal payload** John wants for fast pile-scanning.*
|
|
|
|
---
|
|
|
|
## The change in one line
|
|
The old bridge assumed **barcode → release_id** (you resolve). But a photo of a CD/record **spine**
|
|
almost never shows the barcode (it's on the back). So ScanGod now resolves **`release_id` from
|
|
spine-visible text** — **catalogue number + artist + title** — and sends it to you **pre-resolved**
|
|
(your "if you've already resolved it, send `release_id` and I use it as-is" path). Barcode becomes a
|
|
bonus, not the join key.
|
|
|
|
## How ScanGod resolves it (proven against the full Discogs dump on `ultra`, 2026-06-26)
|
|
Vision reads each spine → `{artist, title, catno, barcode?}`. Then, against `discogs_full`:
|
|
|
|
1. **Catno + title** (the precision key). Catno alone collides globally (e.g. `RCR003` matches dozens
|
|
of labels), so we match normalised catno **AND** a trigram-similar title, filter `release_format='CD'`,
|
|
and prefer country **AU → US → UK** (John's stock is mostly AU pressings + some US imports).
|
|
2. **Artist + title fallback** (no readable catno) → `master_id` → its CD versions → same AU→US→UK pick.
|
|
This also gives a **CD-version count + country list** ("11 CD versions across AU/BR/EU/JP/RU/US").
|
|
|
|
Verified on a real crate photo:
|
|
|
|
| Spine | catno | → release_id | country |
|
|
|---|---|---|---|
|
|
| Def FX — Water | PHMCD-9 | **526717** | Australia (CD) |
|
|
| Falling Joys — Black Bandages | VOLTCD53 | **1218707** | Australia (CD) |
|
|
| Dreamkillers — Pockets Of Water | RCR003 | **8444048** | Australia (CD) — disambiguated from ~30 RCR003 collisions by title |
|
|
| Bad Religion — No Control | *(no catno)* | **8685285** | Australia (CD) via master 58411 |
|
|
|
|
Unreadable / not-in-Discogs spines (logo-only art, obscure pressings) → no `release_id`; ScanGod sends
|
|
title+artist+kind and a Discogs **search link** instead (your non-record / unresolved path already covers this).
|
|
|
|

|
|
|
|
## The minimal payload John wants (per physical item)
|
|
Everything else is a Discogs lookup off `release_id`, so the handoff is tiny:
|
|
|
|
```jsonc
|
|
{
|
|
"release_id": 8444048, // ScanGod-resolved (or null → you fall back to barcode/title)
|
|
"media_condition":"VG+", // human-set at the bench
|
|
"sleeve_condition":"VG", // human-set
|
|
"price": 18.00, // optional — DealGod cross-store median suggestion (human edits)
|
|
"comment": "small spine crack", // optional free text
|
|
"actual_weight_g": 98 // MEASURED on the scale (overrides your 280g default) — John is
|
|
// weighing + photographing as he scans
|
|
}
|
|
```
|
|
|
|
This is a strict subset of the `items[]` you already accept on `POST /admin/intake/scan`
|
|
(`release_id` / `condition` / `sleeve` / `price` / `notes` / `weight_g`). **Nothing new to build** —
|
|
ScanGod just populates `release_id` directly and leaves `barcode` empty.
|
|
|
|
## What (if anything) you might want to do
|
|
- **Nothing required** — the live endpoint already takes `release_id`-as-is + the fields above.
|
|
- **Optional**: mirror the **catno+title matcher** inside RecordGod's own Intake (you have
|
|
`disc_release` + `disc_release_identifier` locally). Same trick: normalise catno (`[^A-Za-z0-9]→''`),
|
|
require a trigram-similar title, prefer AU. Lets your manual intake resolve from a catalogue number,
|
|
not just a barcode. Happy to share the exact SQL.
|
|
- **Country preference** is ScanGod's pick (AU→US→UK); your reviewer can always override the release.
|
|
|
|
## Auth / scope (unchanged, already agreed)
|
|
`Authorization: Bearer <Monster Robot's RecordGod store token>` → your `require_token` → `store_id`.
|
|
Token lives in DealGod's vault, never the client. **This intake path is the enterprise/RecordGod-staff
|
|
feature** — but the *matching* (spine → release_id + price/version intel + Discogs link) ships to **all
|
|
ScanGod customers**; only the "push into inventory" button is gated.
|
