Trace the runtime
Capture inputs, branches, side effects, and outputs from the system that already runs the business.
Language-to-language verification
Proof that translated systems still behave.
Strust verifies mission-critical code conversions across languages, with COBOL-to-Java as the first deep lane: execution traces, equivalence scoring, and review-ready evidence reports.

Method
A verification layer for language migrations that cannot rely on vibes.
Strust is designed around observable behavior. It gives engineering teams a repeatable way to show where a translation is equivalent, where it diverges, and what still needs remediation.
Compare behavior
Run deterministic comparisons between source and target implementations so compiled code cannot hide semantic drift.
Publish evidence
Turn mismatches, parity scores, and coverage gaps into a report leaders and engineers can act on.
Report preview
Show the exact reasons a conversion is ready, blocked, or risky.
The visual language is intentionally plain: tables, deltas, scores, and notes. It should feel like evidence, not decoration.

Java
net = gross.subtract(fee) .setScale(2, HALF_UP);if (net.compareTo(limit) > 0) { status = "REVIEW";
Strust flags the rounding mode before release because the converted path can pass ordinary tests while drifting on financial edge cases.
Why it matters
Compiled does not mean correct.
Language conversions often fail in the details: rounding, ordering, hidden branches, job scheduling, and side effects. Strust gives those details a place to live before they become production incidents.
Validate vendor conversion work before acceptance
Prioritize remediation by business-risk impact
Give executives proof beyond migration velocity
Create a repeatable QA gate for modernization waves
Next step
Bring proof into the conversion review.
Use the report model to evaluate where a real conversion is equivalent, where it has drifted, and what needs remediation.
