Autotuning Execution Core & Per-Worker Observability

The execution core now includes a setpoint-seeking autotuner that converges maxParallel toward a host-configurable target — including at idle, where it previously stalled at 1. Per-worker OpenTelemetry is fully wired into the background-worker model, so phase workers now emit correctly tagged metrics in Grafana, Dash0, and Honeycomb instead of untagged or mis-attributed signal. A reaper poll-fallback fix stops predecessor workers from leaking into liveCount and starving the parallel queue.

Features

  • dev: CTL-760 per-worker OpenTelemetry for the background-worker execution model (#1294) (5399a29)
  • dev: CTL-770 setpoint-seeking autotuner + CTL-771 autotune OTel gauges (#1307) (6f4cfd9)

Bug Fixes

  • dev: CTL-769 give the execution-core reaper a poll-fallback drain (#1304) (068795d)
  • dev: CTL-770 reach idle convergence — autotuner no longer bails at bgCount===0 (#1308) (3cc5c99)
