Live validation on the deployed fix branch caught a real bug: every data-quality
issue's top-of-page "Evidence summary" line rendered the raw, always-English legacy
evidence.summary string unconditionally -- in all three languages -- even though the
backend has been emitting structured, localizable evidence.signals for a while
(app/services/data_quality.py already documented this exact intent). The frontend
side of that conversion was never finished.
- DataQualityIssueDetail.tsx now renders evidence.signals through the operator's
locale as the primary summary; the raw evidence.summary string is only visible
inside "Technical details" (via the existing EvidenceDisclosure JSON dump).
- The four DQ-DEMO-* seed rows that anchor the guided demo's scripted scenarios now
carry real, accurate signals computed at seed time (duplicate-customer's similarity
score is the actual SequenceMatcher ratio on the seeded names, not invented) instead
of only a legacy English sentence.
- Rows with no structured signals (generic filler seed data) fall back to the raw
text rather than showing a blank summary; the one known placeholder string gets its
own localized rendering so it never displays as English filler either.
- New regression test: the vehicle_status_conflict evidence summary must show
localized text and must never contain the specific raw English sentence that was
live-visible before this fix, in all 3 languages.
151 backend tests, Ruff, mypy green; full local Playwright suite green (a couple of
sequential-run-only flakes, both confirmed to pass in isolation and unrelated to this
change).
