+Current status (2026-08-01): the framework is validated, but the official
 campaign has not run (`0/10` controls, `0/30` pairs, `0/60` arms). CTX benefit
 remains unproven; `not_beneficial` is a valid final result.
 
+The pre-selection descriptive contract is frozen in
+`descriptive-metrics-v1.json`. It reports completed shell-command executions,
+failed executions, output bytes, repeated commands, the CTX
+recommend/select/deliver/semantic-use funnel, lifecycle event counts, timeouts,
+and nonzero agent/verifier outcomes. These metrics are descriptive and
+non-confirmatory: they have no thresholds, do not change the primary
+time/token/quality verdict, and do not support a causal claim on their own.
+
+Every assigned arm remains in the descriptive population regardless of outcome.
+Unknown or malformed evidence stays missing rather than becoming zero. Semantic
+use is not inferred from context delivery. The public descriptive block is
+withheld until all 60 unique final arm records are present and authenticated;
+when released, it contains only whole-arm and whole-campaign aggregates, never
+task-level identifiers, commands, outputs, errors, paths, patches, or entity
