Migration 024 adds a server-authoritative cosmetic_catalog table (seeds today's 4 packs). New CatalogService loads it (cached, falls back to a built-in default when the table is absent). entitlements.snapshotForUser is rewritten to the three-way unlock rule — a pack unlocks via: it's free, an explicit grant, lifetime spend >= its threshold, OR premium tier >= its tier. This kills the old bug where ANY purchase (total_credits_purchased>0 -> level 'credits') unlocked EVERY premium pack, and makes '1 credit -> skin A, 10-pack -> pack B' expressible. Credit-buying no longer auto-promotes to a premium tier. Snapshot now ships a catalog summary to the client (the seed for killing the client-side split-brain next). identityService loads + passes the catalog. +13 tests (catalogEntitlements_ultra), suite 48/343 green.
First stone of the P1 foundation (branch feat/credits-catalog-foundation). Next: client consumes the served catalog (retires RK.PACKS), direct payment -> mint 1 credit, then the buy modal reflects the unified model.
