1,041 JSON files mapping (collector number, language) → Scryfall UUID for
every set in Scryfall's default-cards bulk export. The runtime fetches these
on demand from this repository and caches them locally so card images can be
resolved from the rate-free cards.scryfall.io CDN.
File format: cdn_uuid/{setCode}.json
{"cn": {"lang": "uuid"}, ...} — single-faced
{"cn": {"lang": ["frontUuid","backUuid"]}, ...} — DFCs with distinct faces
Generated from the Scryfall default-cards bulk export (June 2026) using the
forge-scryfall-uuid-map CLI tool (PR #10937 in Card-Forge/forge).

Problem
PR #10928 (the runtime CDN fetcher in Card-Forge/forge) needs a UUID for each card to construct non-rate-limited CDN URLs (
cards.scryfall.io). Rather than bundling ~115k individual files with the game, the runtime fetches a single per-set JSON file on demand from this repository and caches it locally.What this PR contains
1,041 JSON files under
cdn_uuid/, one per Scryfall set code:Each file maps collector numbers to per-language Scryfall UUIDs. DFCs with distinct face UUIDs store an array:
{"A-40": {"en": ["front-uuid", "back-uuid"]}}How it was generated
Using the CLI tool from PR #10937 (Card-Forge/forge) against the Scryfall
default-cardsbulk-data snapshot (June 2026):mvn -pl forge-scryfall-uuid-map exec:java \ -Dexec.args="--output-dir cdn_uuid --default-cards"How the runtime uses these files
On the first image lookup for a set, Forge fetches
cdn_uuid/{setCode}.jsonfrom this repository via the GitHub raw content URL, writes it to{cacheDir}/cdn_uuid/{setCode}.json, and resolves all subsequent cards in that set from the local cache — no repeated network requests.Sets not present here (added after this data was generated) fall back silently to the Scryfall API.
Depends on
PR #10928 in Card-Forge/forge — the runtime code that fetches and reads these files.
