# Association NotLoaded on User Posts
## Symptoms
Ecto.Association.NotLoaded raised when accessing user.posts
in UserListLive after filtering.
## Root Cause
Query in Accounts context missing preload for :posts.
## Solution
Added `Repo.preload(:posts)` to `list_users/1`.
## Prevention
Use n1-check skill before shipping list views.
Use rg to search .codex/solutions/ by symptom (e.g., NotLoaded), by tag (e.g., tags:.*preload), or by component (e.g., component: ecto).
