TypeScript Telemetry v4.3.0

Changed

• Redaction no longer modifies the span. LatitudeSpanProcessor used to mask span, event and link
  attributes in place on the shared span object, so every other processor and exporter on the same
  provider also got Latitude's masked values. It now redacts an export-time view (the same pattern
  as the cost view), so other processors see the raw span. Configure their redaction separately.
  RedactThenExportSpanProcessor with a RedactSpanProcessor also redacts a view now. A
  RedactSpanProcessor registered directly on a provider still masks in place, because that is the
  only way a bare processor can affect what later processors export.
• Regex redaction patterns no longer mask the attributes Latitude needs to classify, attribute and
  price a span: gen_ai.operation.name, openinference.span.kind, llm.request.type,
  ai.operationId, latitude.span.kind, span.type, gen_ai.provider.name, gen_ai.system,
  gen_ai.model.provider, llm.system, llm.provider, ai.model.provider,
  gen_ai.request.model, gen_ai.response.model, llm.model_name, embedding.model_name,
  reranker.model_name, ai.model.id and ai.response.model. A broad pattern such as
  /^gen_ai\./ or /.*/ used to mask them, so Latitude dropped the span from cost and usage
  rollups and lost its model attribution. Listing one as an exact string still redacts it.
• Redaction never throws: a mask that throws or returns a non-attribute value masks that value
  with ******, and the span is still exported. Cost is still resolved from the unredacted span, and
  the SDK's own cost attributes are written after redaction, so patterns never mask them. A
  RedactSpanProcessor registered directly on a provider also fails closed in place (span, event
  and link attributes).

Fixed

• A regex pattern with the g or y flag no longer skips every other matching attribute.
  Patterns are matched with String.prototype.search, which ignores lastIndex.
• RedactSpanProcessor no longer writes its default mask into the options object it was given.

Added

• DEFAULT_REDACT_PATTERNS and REDACTION_EXEMPT_ATTRIBUTES exports, so a custom redact can keep
  the defaults (attributes: [...DEFAULT_REDACT_PATTERNS, ...]). A custom redact still replaces
  the defaults rather than adding to them. New ATTRIBUTES keys for the exempt attributes.
• A "Redaction" section in the TypeScript telemetry docs.
