Introduces code.nochebuena.dev/einherjar/cache-valkey — the Valkey cache starter for the Einherjar framework. Absorbs the valkey package from micro-lib and adds three duck-typed adapters that wire directly into auth, web, and auth-jwt. Core: - Provider interface — Get, Set, Del, Exists, Expire, IncrWithTTL, Native() - Component interface — lifecycle.Component + observability.Checkable + Provider - Config struct (EINHERJAR_VALKEY_* env vars) - New(logger, cfg) Component — creates valkey-go client in OnInit; PING in OnStart; logs "valkey: connected" - IncrWithTTL implemented with Lua script (atomic INCR + conditional EXPIRE); race-free fixed-window semantics with no MULTI/EXEC overhead - Priority: LevelDegraded — Valkey outage degrades, does not halt the service Adapters (duck-typed — no import of auth, web, or auth-jwt): - PermissionCache — Get/Set int64 bitmasks as string; satisfies auth/rbac.Cache - RateLimiterStore — fixed-window via IncrWithTTL; satisfies web/mw.RateLimiterStore - Blacklist — Exists/Set "1" with TTL; satisfies auth-jwt.Blacklist Compliance test verifies CT-6, duck-type shape assignments, and full adapter behavioural coverage with a mockProvider (no live server required). - Component interface embeds observability.Identifiable; identifiable.go implements ModulePath and ModuleVersion via runtime/debug.ReadBuildInfo() — prints in launcher banner

## [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.
