The SC asks two things of an effort: high run: that it discovered at least
one dimension AND that the dimension list in the output brief is a TRUE
SUPERSET of the interview-derived ones. activationCheck computed
dimensions - dimensions_baseline >= 1 and returned ok on that alone. A
count delta says nothing about membership: a run that dropped two
interview dimensions and appended three discovered ones is +1 and passed
the check while violating the second half outright. Supersetness was
asserted only by Phase 4.5's prose contract that discovery appends -
nothing read it.
The stats record cannot carry the dimension names that would show it
directly: names are free prose, and lib/exporters/field-allowlist.mjs
denies prose by omission (question, project_dir, brief_path are already
excluded for that reason). So the run attests membership with
dimensions_baseline_preserved, a boolean set in a new Phase 4.5 step 5,
and the gate refuses to call activation OK without it. An ABSENT
attestation fails rather than falling back to the old count-only rule -
otherwise legacy rows would keep passing on the defect.
Producer side wired end to end: the record format, the measurement-fields
prose (five fields -> six), the exporter allowlist, the jsonl-schemas
fixture row, and the --activation-check comment in
docs/storm-measurement.md.
