Vikunja #169 audition result. The 5x5 controlled A/B
(docs/qa/QA-stage-prompt-audition-results-2026-07-16.md) found the curated
guidance block performance-neutral: 5/5 build success both variants, cost
differences within heavy-tailed noise. Trimmed to the single sentence the
gates don't already enforce (scaffolding-scope boundary); dropped the
read-before-write / verify-before-complete / use-exact-feedback nudges that
restate gate-enforced behavior. ON run 3 proved prose doesn't stop failure
loops — deterministic defenses do (filed Vikunja #191/#192, unblocked #78).
