+- **Goal-backward verification**: worker Phase 10 re-reads acceptance criteria and verifies each is actually satisfied before completing
 - **Full-auto by default**: `/flow-code:plan` and `/flow-code:work` require zero interactive questions — AI reads git state, `.flow/` config, and request context to make branch, review, and research decisions autonomously. Default mode is Worktree + Teams + Phase-Gate (all three active). Work resumes from `.flow/` state on every startup (not a special "resume mode"). All tasks done → auto push + draft PR (`--no-pr` to skip)
 - **Cross-platform**: flowctl is a single Rust binary (macOS/Linux). RP plan-review auto-degrades to Codex on platforms where rp-cli is unavailable. Bash hooks degrade gracefully on Windows (skip, don't block)
 - **Session start**: CLAUDE.md instruction (not an enforced hook) — if `.flow/` exists, run `flowctl status --interrupted` to check for unfinished work from a previous session and resume with the suggested `/flow-code:work <id>` command
