All agent instructions for this repository live in AGENTS.md — that is the single source of truth for every agent (Claude Code, Codex, and any other).
- When adding, changing, or removing any rule or guideline, edit
AGENTS.mdonly — do not add instructions to this file.
(Component-specific guides still apply where present: backend/CLAUDE.md, desktop/CLAUDE.md, app/e2e/SKILL.md, desktop/e2e/SKILL.md.)
