- chore: fix dialyzer

# 0.4.4

# 0.4.1

## New Adapters

- **`Cache.PersistentTerm`** — new adapter backed by Erlang's `:persistent_term` for
  extremely fast reads on rarely-written data such as configuration values. TTL is not
  supported; values persist until explicitly deleted.
- **`Cache.Counter`** — new atomic integer counter adapter backed by Erlang's `:counters`
  module. Provides lock-free increment/decrement operations via `put/4` (values `1` or
  `-1`) and injects `increment/1,2` and `decrement/1,2` into consumer modules through
  `use Cache`. Counter references and index maps are stored in `:persistent_term` for
  zero-latency access from any process.

## Strategy Adapters

- **`Cache.Strategy`** — new behaviour for strategy-based adapters. Strategies compose
  over existing cache adapters and receive the underlying adapter module and its resolved
  opts so they can delegate operations appropriately. Adapter tuple format:
  `adapter: {StrategyModule, UnderlyingAdapterOrConfig}`.
- **`Cache.HashRing`** — consistent hash ring strategy using `libring`. Distributes keys
  across Erlang cluster nodes, forwarding operations to the owning node via `:erpc` (or a
  configurable `rpc_module`). The ring tracks node membership automatically via
  `HashRing.Managed` with `monitor_nodes: true`. Includes **read-repair**: on a miss,
  previous ring snapshots (maintained by `Cache.HashRing.RingMonitor`) are consulted to
  lazily migrate keys after rebalancing. Configurable options: `ring_opts`,
  `node_weight`, `rpc_module`, `ring_history_size`.
- **`Cache.MultiLayer`** — cascades reads and writes through multiple cache layers (e.g.
  ETS → Redis). Reads walk fastest → slowest with automatic backfill on a slower-layer
  hit. Writes go slowest → fastest to ensure durability. Supports an optional `on_fetch`
  callback on total miss and a `backfill_ttl` for backfilled entries.
- **`Cache.RefreshAhead`** — proactively refreshes hot keys in the background before
  their TTL expires. On `get`, if the value is within the `refresh_before` window, the
  current value is returned immediately and an async `Task` refreshes it. Uses a per-cache
  ETS deduplication table and `:global` distributed locking to prevent redundant refreshes
  across nodes. Requires a `refresh_before` (ms) opt and a `refresh/1` callback or
  `on_refresh` opt.

## Test Utilities

- **`Cache.CaseTemplate`** — new ExUnit case template for applications with many test
  files. Define a `CacheCase` module once with `default_caches` or `supervisors`, then
  `use MyApp.CacheCase` in any test file to get automatic sandboxed cache setup. Supports
  per-file additional caches via `:caches` and detects duplicate cache registrations at
  setup time.
