📝 Walkthrough

The change adds cosmetic kind definitions, wire conversion, resolution, and store operations for loading, ownership, rendering, equip, and unequip. It also retains worn cosmetics in profile caches, adds cosmetic telemetry and dashboard widgets, and tests these flows.

Changes: Cosmetics feature

Layer / File(s) Summary
Cosmetic contracts and wire conversion
src/cosmetics/types.ts, src/cosmetics/wire.ts, src/cosmetics/wornEntry.ts, src/cosmetics/reviveWorn.ts, src/cosmetics/defineCosmeticKind.ts, src/cosmetics/kinds/*, test/cosmetics/wire.test.ts
Adds cosmetic types, kind definitions, wire adapters, and worn-entry revival. Tests cover conversions, invalid values, and revival.
Kind registry and cosmetic resolution
src/cosmetics/registry.ts, src/cosmetics/resolver.ts, src/cosmetics/optionOn.ts
Registers kind modules and resolves catalogue rows, options, and worn entries. Resolution reports failures, skips unsupported or disabled kinds, and orders results by layer.
Worn cosmetics in profile cache
src/store/data/profileCacheStore.ts, src/store/db/dexie.ts, test/store/profileCacheUpgrade.test.ts, test/store/profilePrefetch.test.ts
Adds cosmetics to profile status and cache updates, tracks profile revisions, and revives cached worn entries. Database version 11 clears profile-cache rows while retaining other stores. Tests cover cache updates, revisions, realtime merges, and the upgrade.
Cosmetics loading and equip operations
src/store/features/cosmeticsStore.ts, src/store/features/ensureCosmeticsLoaded.ts, src/store/system/apiStore.ts, src/store/system/appState.ts, src/store/system/systemStore.ts, scripts/sentry/dashboards.ts, test/store/cosmeticsStore.test.ts
Adds catalogue and grant loading, retry and session handling, resolution and ownership queries, equip and unequip operations, and initialization and reconnect loading. Adds cosmetic metrics and dashboard widgets; store tests cover these behaviors.

Merge Risk: 🔵 Low · up to db68b

Concurrent changes to the same cosmetic can leave the displayed and cached look out of sync. Guard against stale responses; the risk is limited to this ordering case.

Guard same-kind responses against stale operations.

IEquipResult permits both SuccessEquip(profile) and FailedEquip(NOT_FOUND), and the API exposes independent Equip and Unequip requests. If an earlier Unequip response settles after a newer Equip response, both calls pass the session generation check. unequip then calls forgetWornKind, which removes the newly equipped entry from me.meProfile and the profile cache. Track the latest operation for each kind and apply success or NOT_FOUND cleanup only for that operation.
