A new validator has been added that recognizes a specific pattern: one or more alphanumeric identifiers (each starting with a letter, up to 64 characters, allowing underscores), separated by commas or plus signs. Values matching this pattern are now treated as safe and passed through as-is; anything else is redacted as \"nonconforming\".\n\n**Why**\n\nThis lets telemetry preserve useful structured values, like lists of identifiers, without redacting them, while still catching and hiding anything that doesn't fit the expected shape.\n\n- Area: Telemetry\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 1\/5"}
