- Metric/trace service unification is promised only when service.namespace
is empty and job is not relabeled (the compatibility spec renders job as
<namespace>/<name>); otherwise alignment needs pipeline normalization or
explicit declarations.
- Entity row contract stated once (per projected observation); the calls
defining SQL is marked as the single-column simplification of the
declaration-derived endpoint ids; Remote Write 2.0 metadata intake and
the Prometheus implicit declarations are listed as M1 work.
- Compress survey/example/reference prose.
