Aggregated findings:**\n\n### Code Reuse Review\n- No new functions or duplicate logic were introduced. The refactor purely collapses existing fields into an `Option<PullRequestConfig>`, replacing `pull_request_enabled: false, pull_request_draft: false` with `pull_request: None` everywhere.\n- `AutoMergeConfig` is already gone (confirmed via grep — zero matches).\n- No old flat fields (`pull_request_enabled`, `pull_request_draft`) remain anywhere.\n\n### Code Quality Review  \n- **`maybe_open_pull_request` still takes `draft: bool`** — The goal mentioned changing this to take `&PullRequestConfig`, but keeping `draft: bool` is the right call here. The `pr.rs` CLI command (`fabro pr create`) hardcodes `draft: true` and doesn't have a `PullRequestConfig` object. Changing the function to require `&PullRequestConfig` would force creating a throwaway config struct. The `#[allow(clippy::too_many_arguments)]` is already present. **Not an issue — skip.**\n- **`enabled` field on `PullRequestConfig` is redundant at runtime** — This is by design. The field is needed for TOML deserialization (`enabled = true`), and the construction in `run.rs` correctly filters it out with `.filter(|p| p.enabled).cloned()`. **Not an issue — working as intended.**\n- **Nesting depth in `run.rs`** — The `if let Some(ref pr_cfg)` adds one level of nesting, but the overall structure is clearer: the entire PR block is scoped under the Option check, with a clean `else` branch for the debug log. **Acceptable.**\n\n### Efficiency Review\n- **`.cloned()` on `PullRequestConfig`** — `PullRequestConfig` has only 2 `bool` fields (2 bytes). Clone cost is negligible. **Not an issue.**\n- No unnecessary allocations, redundant computations, or TOCTOU patterns introduced.\n\n### Verification\n- `cargo build --workspace` ✅\n- `cargo clippy --workspace -- -D warnings` ✅  \n- `cargo test -p fabro-workflows -- pull_request run_config project_config` ✅ (1 passed)\n- `cargo fmt --check --all` ✅\n\n**Conclusion: The code is clean. No fixes needed.**",

After reviewing all changes across the three dimensions:\n\n**Code Reuse:** No issues found. The `.and_then().filter().cloned()` chain is idiomatic Rust and doesn't duplicate any existing utility. The pattern is simple enough not to warrant extraction.\n\n**Code Quality:** No issues found. The refactoring is clean:\n- `None` = disabled, `Some(config)` = enabled — this correctly eliminates the redundant boolean at the `RunConfig` level\n- The `enabled` field on `PullRequestConfig` is retained only for TOML deserialization (as designed), and filtered out via `.filter(|p| p.enabled)` during construction\n- The `maybe_open_pull_request` function correctly keeps `draft: bool` as a parameter since it's also called from `pr.rs` where no `PullRequestConfig` is available\n- The restructured `if let Some(ref pr_cfg)` block in `run.rs` is cleaner than the original flat if-else chain\n\n**Efficiency:** No issues found. The `.cloned()` on `PullRequestConfig` (which is just `bool` + `bool`) is negligible. No new file reads, no redundant work, no hot-path bloat.\n\nAll verification checks pass: build ✅, clippy ✅, tests ✅, fmt ✅.",
