# `Tay.Storage.Recovery.EventDecoder`
[🔗](https://github.com/AndriiSydorenko1904/tay/blob/v1.6.1/lib/tay/storage/recovery/event_decoder.ex#L1)

Explicit semantic capability boundary for recovery, not a physical Record codec.

Providers are trusted, explicitly configured modules. They must stay fixed for
an attempt, decode into inert values, enforce budgets during decoding, and
report exact payload consumption. No worker resolution, atom creation, fallback,
external side effect or implicit support is permitted. `Tay.Event` supplies
the separately approved production Event v1 implementation; this behaviour
does not itself assign types, schemas or payload bytes.

# `limits`

```elixir
@type limits() :: %{
  depth: pos_integer(),
  output_nodes: pos_integer(),
  binary_bytes: non_neg_integer()
}
```

# `decode_payload`

```elixir
@callback decode_payload(1..254, 1..255, binary(), limits()) ::
  {:ok, term(), non_neg_integer()} | {:error, term()}
```

# `known_type?`

```elixir
@callback known_type?(1..254) :: boolean()
```

# `supported_schema?`

```elixir
@callback supported_schema?(1..254, 1..255) :: boolean()
```
