# `PaperTiger.Store.Reviews`
[🔗](https://github.com/EnaiaInc/paper_tiger/blob/v1.2.2/lib/paper_tiger/store/reviews.ex#L1)

ETS-backed storage for Review resources.

Uses the shared store pattern via `use PaperTiger.Store` which provides:
- GenServer wraps ETS table
- Reads go directly to ETS (concurrent, fast)
- Writes go through GenServer (serialized, safe)

## Architecture

- **ETS Table**: `:paper_tiger_reviews` (public, read_concurrency: true)
- **GenServer**: Serializes writes, handles initialization
- **Shared Implementation**: All CRUD operations via PaperTiger.Store

## Examples

    # Direct read (no GenServer bottleneck)
    {:ok, review} = PaperTiger.Store.Reviews.get("prv_123")

    # Serialized write
    review = %{id: "prv_123", payment_intent: "pi_123", ...}
    {:ok, review} = PaperTiger.Store.Reviews.insert(review)

    # Query helpers (direct ETS access)
    reviews = PaperTiger.Store.Reviews.find_by_payment_intent("pi_123")

# `child_spec`

Returns a specification to start this module under a supervisor.

See `Supervisor`.

# `clear`

```elixir
@spec clear() :: :ok
```

Clears all reviews from the store (all namespaces).

**Serialized write** - goes through GenServer.

Useful for test cleanup. Note: This clears ALL data, not just
the current namespace. For namespace-specific cleanup, use
`clear_namespace/1`.

# `clear_namespace`

```elixir
@spec clear_namespace(pid() | :global | {pid() | :global, String.t()}) :: :ok
```

Clears all reviews for a specific namespace.

Used by `PaperTiger.Test` to clean up after each test.

# `count`

```elixir
@spec count() :: non_neg_integer()
```

Counts total reviews in current namespace.

**Direct ETS access** - does not go through GenServer.

# `delete`

```elixir
@spec delete(String.t()) :: :ok
```

Deletes a review from the store.

**Serialized write** - goes through GenServer.
Data is scoped to the current test namespace.

# `find_by_payment_intent`

```elixir
@spec find_by_payment_intent(String.t()) :: [map()]
```

Finds reviews by payment intent ID.

**Direct ETS access** - does not go through GenServer.

# `get`

```elixir
@spec get(String.t()) :: {:ok, map()} | {:error, :not_found}
```

Retrieves a review by ID.

**Direct ETS access** - does not go through GenServer.
Data is scoped to the current test namespace.

# `insert`

```elixir
@spec insert(map()) :: {:ok, map()}
```

Inserts a review into the store.

**Serialized write** - goes through GenServer to prevent race conditions.
Data is scoped to the current test namespace.

# `list`

```elixir
@spec list(keyword() | map()) :: PaperTiger.List.t()
```

Lists all reviews with optional pagination.

**Direct ETS access** - does not go through GenServer.
Data is scoped to the current test namespace.

## Options

- `:limit` - Number of items (default: 10, max: 100)
- `:starting_after` - Cursor for pagination
- `:ending_before` - Reverse cursor

# `list_namespace`

```elixir
@spec list_namespace(pid() | :global | {pid() | :global, String.t()}) :: [map()]
```

Returns all items in a specific namespace.

Useful for debugging test isolation.

# `prefix`

```elixir
@spec prefix() :: String.t() | nil
```

Returns the ID prefix for this resource.

# `start_link`

```elixir
@spec start_link(keyword()) :: GenServer.on_start()
```

Starts the review store GenServer.

# `table_name`

```elixir
@spec table_name() :: atom()
```

Returns the ETS table name for this store.

# `update`

```elixir
@spec update(map()) :: {:ok, map()}
```

Updates a review in the store.

**Serialized write** - goes through GenServer.
Data is scoped to the current test namespace.
