Every host step now opens a stage scope, so observations recorded inside it (including cross-task plugin/RPC calls resolved through the execution registry) carry the owning step as parent; the pipeline lane records its own pipeline/run node so acks and replies issued outside the runner still hang off a node.
close_trace() called the coroutine TelemetryManager.start_send_task without
awaiting or scheduling it, so every payload closed on that path was silently
dropped and the runtime logged "coroutine ... was never awaited". The only
other caller awaits it correctly, so both call styles stay supported: call the
manager, schedule the returned coroutine on the running loop, and close it with
a debug log when no loop is available.
Regression case added in tests/unit_tests/telemetry/test_trace.py: it fails
before this change (payload never delivered) and passes after.
Execution telemetry already reported window counters. This adds one bounded,
content-free chain per inbound platform event, so a single event can be
followed from its source platform through routing and processing to the
platform API calls it caused.
- telemetry/trace.py: ContextVar trace identity with route and run scopes, and
a 32-stage bound per chain.
- telemetry/execution.py: keeps at most 64 chains for 120s, decides sampling
from the observed outcome, and sends one payload per chain keyed by
query_id = trace_id, so Space fetches a chain by primary identity. Window
counters are unchanged and remain the source of coverage statistics.
- botmgr / pipelinemgr / orchestrator: bind the trace at the ingress boundary,
scope routing identity per dispatch, and attach the run identity, so nested
lanes (event -> route -> pipeline/runner -> platform API) reuse one chain. A
run reached without an ingress (WebUI debug, service API) owns its own chain.
- space.execution_trace selects off | failures | sampled | all (default
sampled: failures, WebUI debug runs and every N-th success).
Chains carry only code-defined identifiers (adapter and runner types, route
identity as type:uuid, run id); never message content, tool arguments or
platform user identifiers.
