Steg 20 (remediation Wave 4 / S5, SOLO): measure whether the 7-agent long-form
review stack carries redundant gates. Method: cross-reference each agent's check
taxonomy against its in-repo fasit fixture; four fixtures (editorial, content,
language, fact-reviewer) target the SAME Del 4 edition, enabling a real
cross-gate overlap comparison on one piece (not a live run — fixtures' own
live-run notes require a reload + cross-repo Maskinrommet access, out of scope).
Finding: every gate has >=1 unique catch on Del 4. The four genuine overlaps
(verbatim repetition, the Vi/Vi-i-Nav quote, the postulated number, the
small-orgs thread) are each justified — a cold re-take (Endring 9's reason to
exist), the same symptom via a different operation (flag-absence vs web-verify),
or two distinct defects sharing a surface topic — with no subsumption either way.
The fact-checker <-> fact-reviewer overlap is load-bearing (the pivot premise
arrived after Step 5, so only the cold re-run caught it).
Decision: NO TRIM. voice-scrubber has no fixture -> inconclusive; redundancy
retained (Step 20 On-failure = skip). Counts unchanged 19 agents / 27 commands;
count contract (EXPECT_AGENTS=19) untouched. test-runner 62/62 green.
