TypeScript Telemetry v4.1.0

on GitHub

Added

• injectTraceContext() / extractTraceContext() / withTraceContext() carry the active span and
  Latitude context across a boundary with no ambient OpenTelemetry context, so a second agent in its
  own Cloudflare Durable Object joins the caller's trace instead of orphaning one. Injecting from
  inside a tool's execute parents the callee on that tool call, which is what makes it render as a
  subagent. The carrier is keyed by HTTP header names, so one object serves an RPC argument and
  fetch headers, and an absent or malformed carrier leaves the callee a root rather than failing.
• withParentContext(tracer, context) attaches a framework-owned tracer's first span to a remote
  parent while leaving nested spans on their real parents.
• createDurableObjectTelemetry() flushes at each unit of work, which is the only reliable point on
  a runtime that evicts without warning. Exports are serialized and coalesced, a caller arriving
  mid-export gets a later one, in-flight exports register with ctx.waitUntil(), and a failed
  export is reported instead of failing the turn.
• The Cloudflare Think guide and runnable example cover multi-agent propagation and eviction-safe
  flushing, including a second Planner agent in its own Durable Object.

Fixed

• Constructing Latitude no longer assumes process.once exists, so it works on runtimes without
  Node signal handling.
• Smart filter now promotes ancestors of kept spans (including already-ended parents held briefly
  after a drop) so exported traces stay connected when only a descendant independently passed the
  filter — e.g. a stamped tcp.connect no longer ships without its parent.
