This makes the `run` command's arg surface complex with `conflicts_with` annotations, and the UX is unintuitive — users must construct `fabro/run/RUN_ID` branch names manually.

     "internal.retry_count.preflight_lint": 1,
     "response.simplify_opus": "Here's a summary of what was fixed:\n\n### Fixes Applied\n\n1. **Eliminated ~120 lines of duplicated code in `resume.rs`** (604 → 420 lines, -184 lines): The two code paths (checkpoint-file and git-branch) had nearly identical blocks for: interviewer creation, dry-run detection, model/provider resolution, engine construction, retro generation, result printing, and exit code logic. Restructured into three functions:\n   - `prepare_from_checkpoint()` — loads checkpoint/graph from files, creates simple local sandbox\n   - `prepare_from_branch()` — resolves run ID from git, reads metadata, sets up worktree sandbox\n   - `run_resumed()` — shared tail handling engine setup, execution, retro, and result display\n   - A `ResumeContext` struct carries the divergent state between the two paths\n\n2. **Extracted `default_run_dir()` helper in `run.rs`** — The run-dir defaulting logic (`~/.fabro/runs/YYYYMMDD-RUNID` or `/tmp/fabro-dry-run/RUNID`) was duplicated 4 times across `run.rs`, `create.rs`, and resume.rs. Now it's a single `pub(crate)` function reused by all three.\n\n3. **Used `resolve_model_provider()` in resume.rs** — The original code had an inline simplified version that skipped model alias expansion (e.g., `--model opus` wouldn't resolve to `claude-opus-4-6`) and ignored graph `default_model`/`default_provider` attributes. Now it calls the full precedence chain through the existing tested helper.\n\n4. **Simplified `RunSpec` Default impl** — Replaced the manual 16-field `impl Default for RunSpec` with `#[derive(Default)]` since all fields (`String`, `PathBuf`, `HashMap`, `bool`, `Option`) have built-in Default impls.\n\n5. **Fixed missing trailing newlines** in `docs/core-concepts/how-fabro-works.mdx` and `docs/reference/cli.mdx`.\n\n### Verification\n- `cargo build --workspace` ✅\n- `cargo test --workspace` ✅ (all tests pass)\n- `cargo clippy --workspace -- -D warnings` ✅ (no warnings)\n- `cargo fmt --check --all` ✅",

Documentation (`docs/`)\n- Update `docs/reference/cli.mdx`: add `fabro resume` section, remove `--resume`/`--run-branch` from `fabro run`\n- Update `docs/execution/checkpoints.mdx`: change resume examples\n- Update any other docs referencing `fabro run --run-branch` or `fabro run --resume`\n\n## Verification\n\n1. `cargo build --workspace` — compiles cleanly\n2. `cargo test --workspace` — all tests pass\n3. `cargo clippy --workspace -- -D warnings` — no warnings\n4. Manual: `fabro resume --help` shows expected args\n5. Manual: `fabro run --help` no longer shows `--resume` or `--run-branch`\n\n\n## Completed stages\n- **toolchain**: success\n  - Script: `command -v cargo >/dev/null || { curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh -s -- -y && sudo ln -sf $HOME/.cargo/bin/* /usr/local/bin/; }; cargo --version 2>&1`\n  - Stdout:\n    ```\n    cargo 1.94.0 (85eff7c80 2026-01-15)\n    ```\n  - Stderr: (empty)\n- **preflight_compile**: success\n  - Script: `cargo check -q --workspace 2>&1`\n  - Stdout: (empty)\n  - Stderr: (empty)\n- **preflight_lint**: success\n  - Script: `cargo clippy -q --workspace -- -D warnings 2>&1`\n  - Stdout: (empty)\n  - Stderr: (empty)\n- **implement**: success\n  - Model: claude-opus-4-6, 91.6k tokens in / 34.3k out\n  - Files: /home/daytona/workspace/docs/core-concepts/how-fabro-works.mdx, /home/daytona/workspace/docs/execution/checkpoints.mdx, /home/daytona/workspace/docs/reference/cli.mdx, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/create.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/fork.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/mod.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/resume.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/rewind.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/run.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/start.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/main.rs, /home/daytona/workspace/lib/crates/fabro-cli/tests/cli.rs, /home/daytona/workspace/lib/crates/fabro-workflows/src/run_spec.rs\n- **simplify_opus**: success\n  - Model: claude-opus-4-6, 78.4k tokens in / 21.0k out\n  - Files: /home/daytona/workspace/docs/core-concepts/how-fabro-works.mdx, /home/daytona/workspace/docs/reference/cli.mdx, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/create.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/resume.rs, /home/daytona/workspace/lib/crates/fabro-cli/src/commands/run.rs, /home/daytona/workspace/lib/crates/fabro-workflows/src/run_spec.rs\n- **simplify_gpt**: fail\n- **verify**: success\n  - Script: `cargo clippy -q --workspace -- -D warnings 2>&1 && cargo nextest run --cargo-quiet --workspace --status-level fail 2>&1`\n  - Stdout:\n    ```\n    ────────────\n     Nextest run ID 1c2ebdac-559c-450f-90fb-ddc9a90a8e1b with nextest profile: default\n        Starting 3287 tests across 41 binaries (177 tests skipped)\n    ────────────\n         Summary [  17.806s] 3287 tests run: 3287 passed, 177 skipped\n    ```\n  - Stderr: (empty)\n",
