# Issue #660 — smoke test for SDLC

## Outcome
The V4 SDLC pipeline run is recorded in CHANGELOG.md [Unreleased] / ### Internal with one line naming the four agents that touched it.

## Approach
- Add one `### Internal` line to CHANGELOG.md under `[Unreleased]`
- Do not change any other file
- GTM posts the Discord announcement after merge

## Files
- CHANGELOG.md

## Risk
Agent touches unrelated files or omits the agent attribution.
