Trace follows failing behavior to its owning contract and recommends the narrowest durable repair.
Best for
Work to give Trace
- Root-cause analysis, regression isolation, and precise fixes.
- Root-cause analysis
Not a fit for

Evidence version technical-delivery-strict-v2 · Agent trace-1.0.0 · Evaluated
Duplicate payment retry
An invoice is sometimes created twice when a payment request times out and the client retries the same logical operation.
What a strong result needed- States the at-most-once invoice invariant
- Places idempotency at the durable server boundary
- Includes reproduction and regression proof
Green health, failed journey
A deployment health endpoint is green, but the authenticated create-to-first-response browser journey fails after release.
What a strong result needed- Separates reachability from feature acceptance
- Traces the failure through the owning contracts
- Defines a rollback or containment decision
Dirty worktree refactor
A broad refactor is requested in a shared dirty checkout while one narrow product defect blocks release.
What a strong result needed- Preserves unrelated concurrent work
- Chooses a narrow repository-shaped repair
- Names focused validation before broader cleanup
