Truth Guard

Truth Guard is CaseSolo's deterministic legal-safety layer for AI outputs. It runs after generation and before consequential output is treated as safe for user-facing legal work.

What It Checks

src/lib/ai/truth-guard.ts currently verifies:

• Citation references resolve to retrieved source spans.
• Quantitative/date claims are cited when source spans are available.
• Dates are plausible and do not precede the incident date unless flagged.
• Large uncited dollar claims are warned.
• Jurisdiction-specific statute references fit the case state.
• Unsafe overconfident language is warned.
• SOL year/date claims match the sourced state rule catalog.
• Answer-deadline day claims match the jurisdiction deadline table.

Rule Sources

src/lib/legal/sol-database.ts is the shared SOL catalog for all 50 states plus DC. Each row includes:

• years
• statute
• sourceUrl where currently available
• sourceLastReviewed
• claimScope
• verification
• notes

Florida's current general negligence baseline is two years under Fla. Stat. § 95.11(5)(a). Entries marked claim_specific_review_required produce warnings rather than hard blocks so the product does not overstate certainty when the governing rule can depend on claim classification.

Integration Points

• src/lib/cases/deadline-rules.ts generates SOL deadline rules from the shared SOL catalog and carries source citations into calculated deadlines.
• src/app/api/sol-calculator/route.ts exposes statute/source metadata with SOL results.
• src/app/api/dashboard/sol-heatmap/route.ts uses the shared catalog for general PI baselines.
• Truth Guard report issues include ruleCitation, sourceUrl, expectedValue, and actualValue where applicable.

Verification

Run the focused rule checks with:

npm run test:run -- sol-database deadline-rules truth-guard

Task-level verification should also include targeted ESLint, npm run typecheck, and git diff --check.
