Layer 4: JSON Validation

This layer attempts to validate and parse clean JSON using Jason. It serves as the final validation layer in the pipeline, confirming that the JSON is valid and ready for consumption.

Key responsibilities:

  • Validate JSON syntax using Jason
  • Parse valid JSON into Elixir terms
  • Apply fast path optimization for valid JSON
  • Handle Jason.DecodeError gracefully
  • Pass malformed JSON to next layer for repair

Examples

iex> JsonRemedy.Layer4.Validation.process("{"name": "Alice"}", %{repairs: [], options: []})
{:ok, %{"name" => "Alice"}, %{repairs: [], options: [], metadata: %{layer4_processed: true}}}

iex> JsonRemedy.Layer4.Validation.process("{name: 'Alice'}", %{repairs: [], options: []})
{:continue, "{name: 'Alice'}", %{repairs: [], options: []}}

supports?(input)
