 When the user corrects a recurring behavior, the workspace should update the file that controls that behavior:
 
+- `core/` for reusable project-independent behavior
+- `profiles/<project>/` for project-specific assumptions
 - `.opencode/commands/` for slash commands
 - `prompts/` for reusable drafting templates
 - `.opencode/agents/` and `ai/AGENTS.md` for default agent behavior
