Goal: define a minimal shared vocabulary for metrics keys, units, and attachment points.

1. Normatives to evaluate

  • Core metric keys and meanings (counts, probabilities, durations)

  • Units conventions (e.g., Ms suffix, rates 0..1)

  • Extension metric naming (namespaced keys)

2. Informatives to evaluate

  • Aggregation guidance (sum counts, recompute rates, percentile strategies)

  • Example metric payloads on observed state/transition objects

3. Decisions to make

  • Which metrics are core vs profile-defined?

  • Do you standardize histograms/sketches now or defer?

4. Must-align with
