# Feature flags module

## Behavior

- no in-memory caching; each check reads from the database
- a flag must exist and be globally enabled before any access grant matters
- grants can target a guild, a user, or a role

## Main entrypoints

- `isFlagEnabled(flagName)`
- `hasAccess(flagName, { guildId, userId, memberRoles })`
- `createFlag(name, description?)`
- `setFlagEnabled(name, enabled)`
- `grantAccess(flagName, { guildId?, userId?, roleId? })`
- `revokeAccess(accessId)`
- `listFlags()`
- `listAccess(flagName)`
- `deleteFlag(name)`

## Command integration

- `bot/lib/handlers/CommandHandler.ts` checks beta commands through this service
- if a command does not set `featureFlag`, the slash command name is used as the fallback flag name
