# LDC-E1360 — Snapshot content collision in composition

## What it means

Not triggerable in a hermetic recipe.

A composite case merges export snapshots: the same StableId presented twice with different content is a collision, not a merge (`CONTENT_CODE` in the compose flow). Reaching it needs at least two case-export snapshots composed together — snapshot directories with a documents subdir — while hermetic recipes run single files. If you meet the code in real output, read it as "two snapshots disagree about one id" and reconcile the sources before composing.
