// Safe JSON.parse helper shared by the translator layer.
|
|
//
|
|
// Behavior contract (must be preserved by all callers):
|
|
// - non-string input is returned unchanged (passthrough)
|
|
// - a valid JSON string is parsed and returned
|
|
// - on parse error the caller-chosen `fallback` is returned
|
|
//
|
|
// The `fallback` is explicit so the two historical `tryParseJSON` variants
|
|
// can keep their distinct semantics: geminiHelper returns `null` on error,
|
|
// while openai-to-claude returns the raw input string (passthrough).
