## [1.0.0] — 2026-05-28

### Added

- `Provider` interface: six common Valkey operations (`Get`, `Set`, `Del`, `Exists`,
  `Expire`, `IncrWithTTL`) using only standard Go types, plus `Native() vk.Client`
  escape hatch.
- `Component` interface: `Provider` + `lifecycle.Component` + `observability.Checkable`.
- `Config` struct with `EINHERJAR_VALKEY_*` env tags (caarlos0/env compatible).
- `New(logger, cfg) Component` factory — lifecycle-aware Valkey client.
- `NewPermissionCache(Provider) *PermissionCache` — satisfies `auth/rbac.Cache`
  via duck typing.
- `NewRateLimiterStore(Provider, window, limit) *RateLimiterStore` — satisfies
  `web/mw.RateLimiterStore` via duck typing; fixed-window Lua counter.
- `NewBlacklist(Provider) *Blacklist` — satisfies `auth-jwt.Blacklist` via duck typing.
