FRONT-05 (ABSA Loopback Fragility) & FRONT-07 (ReportViewer Risk Label Drift)

Release digest

FRONT-05 (ABSA Loopback Fragility) — Replaced localhost self-call for corporate ABSA trigger with in-process execution path in backend/routers/corporate.py (/api/analytics/analyze/{company_slug}).
FRONT-07 (ReportViewer Risk Label Drift) — Updated dashboard_app/src/components/ReportViewer.jsx to use backend-aligned risk thresholds and labels: LOW (>=80), MEDIUM (>=60), HIGH (>=40), CRITICAL (<40).
FRONT-08 (Timeline Company Filter Drift) — /api/timeline now resolves canonical company identity and applies exact-match filtering (LOWER(company_name) = LOWER(%s)) instead of broad fuzzy ILIKE matching.
PDF-04 (Synthetic Topic Fallback Masking) — Removed hardcoded synthetic top-topic placeholders in PDF download path when aspect query fails. X-Topics-Status response header added (ok, empty, unavailable).

Added tests/test_block14_frontend_pdf_consistency.py covering:
- no ABSA localhost loopback contract
- exact timeline filtering contract
- ReportViewer threshold/label parity with backend risk mapping
- no synthetic PDF topics fallback contract
Full regression: 212 passed, 2 skipped, 22 deselected.
Added docs/reports/2026-03-06_BLOCK14_VERIFICATION_REPORT.md.
Synced main/internal/public documentation for Block 14 contracts.
