Here's a summary of what was fixed:\n\n## Fixes Applied\n\n### 1. Extracted `WorktreeEvent → WorkflowRunEvent` callback helper (3 → 1)\nThe same 12-line match block mapping `WorktreeEvent` variants to `WorkflowRunEvent` was duplicated in three places:\n- `run.rs`: new-run path (`SandboxProvider::Local`)\n- `run.rs`: resume path (`run_from_branch`)\n- `parallel.rs`: branch worktree setup\n\n**Fix:** Added `fn worktree_event_callback(emitter: Arc) -> WorktreeEventCallback` to each file as a local helper, replacing all three inline match blocks with a single call.\n\n### 2. Extracted `LocalSandbox + event_callback` helper (3 → 1)\nIn `run.rs`, the pattern `let mut env = LocalSandbox::new(cwd); env.set_event_callback(...); Arc::new(env)` appeared twice in the same match arm (fallback on error + else branch) and again in `run_from_branch`.\n\n**Fix:** Added `fn local_sandbox_with_callback(cwd: PathBuf, emitter: Arc) -> Arc` and replaced all three sites.\n\n### 3. Eliminated `.clone().unwrap()` on `Option`\n`worktree_base_sha.clone().unwrap()` (and same for `branch_name`, `wt_path`) cloned the entire `Option` before unwrapping. \n\n**Fix:** Changed `if worktree_base_sha.is_some()` to `if let (Some(base_sha), Some(branch_name), Some(wt_path)) = (worktree_base_sha.as_ref(), ...)` — borrows the inner values directly, then only clones the `String`/`PathBuf` when actually needed for `WorktreeConfig`.\n\n### 4. Fixed `.to_string_lossy().to_string()` → `.into_owned()` (3 sites)\n`.to_string_lossy().to_string()` calls `.to_string()` on a `Cow`, which allocates a new `String` even when `Cow` is already `Owned`. `.into_owned()` moves directly from `Cow::Owned` without the extra allocation.", - "current_node": "verify", + "current_node": "fixup", "thread.simplify_gpt.current_node": "verify", + "thread.verify.current_node": "fixup", "internal.node_visit_count": 1, "internal.retry_count.simplify_gpt": 1, "response.implement": "Zero failures and zero errors. Let me provide a summary of all changes made:\n\n## Summary of Changes\n\n### New file: `lib/crates/fabro-sandbox/src/worktree.rs`\n- Defines `WorktreeEvent` enum (BranchCreated, WorktreeAdded, WorktreeRemoved, Reset)\n- Defines `WorktreeEventCallback` type alias\n- Defines `WorktreeConfig` struct (branch_name, base_sha, worktree_path, skip_branch_creation)\n- Implements `WorktreeSandbox` struct wrapping `Arc` with:\n - `initialize()`: runs git branch + worktree remove + worktree add + reset, emitting events; does NOT call inner's `initialize()`\n - `cleanup()`: runs git worktree remove, emits WorktreeRemoved; does NOT call inner's `cleanup()`\n - `working_directory()`: returns `config.worktree_path`\n - `exec_command()`: defaults `working_dir` to `config.worktree_path` when `None`\n - All other `Sandbox` methods delegate to inner\n- 14 unit tests covering all specified behaviors (TDD green)\n\n### Modified: `lib/crates/fabro-sandbox/src/test_support.rs`\n- Added `captured_commands: Mutex>` to `MockSandbox` (captures all commands in sequence)\n- Added `captured_working_dirs: Mutex>>` to `MockSandbox` (captures working_dir per call)\n- Updated `exec_command()` to populate both new fields alongside existing `captured_command`\n\n### Modified: `lib/crates/fabro-sandbox/src/lib.rs`\n- Added `pub mod worktree;`\n- Added `pub use worktree::{WorktreeConfig, WorktreeEvent, WorktreeEventCallback, WorktreeSandbox};`\n\n### Modified: `lib/crates/fabro-agent/src/sandbox.rs` + `lib.rs`\n- Re-exported `WorktreeConfig`, `WorktreeEvent`, `WorktreeEventCallback`, `WorktreeSandbox` from `fabro_sandbox`\n- Also re-exported `shell_quote` (which was already in `sandbox.rs` but not in `lib.rs`)\n\n### Modified: `lib/crates/fabro-workflows/src/handler/parallel.rs`\n- Removed the private `WorktreeSandbox` struct and its full `impl Sandbox` (126 lines deleted)\n- Removed `use fabro_agent::LocalSandbox`\n- Added `use fabro_agent::{WorktreeConfig, WorktreeEvent, WorktreeSandbox}`\n- Replaced the inline git setup loop (branch creation, worktree add, reset, `is_remote()` branch for sandbox type) with a `WorktreeSandbox` that handles all of this uniformly for any inner sandbox\n\n### Modified: `lib/crates/fabro-cli/src/commands/run.rs`\n- Added `WorktreeConfig`, `WorktreeEvent`, `WorktreeSandbox` to imports\n- **New runs**: Replaced `setup_worktree()` call with inline config computation (head_sha, branch_name, worktree_path), and replaced `LocalSandbox::new(cwd)` in `SandboxProvider::Local` with `WorktreeSandbox::new(LocalSandbox(original_cwd), config)` + `initialize().await` + `set_current_dir()`; graceful fallback on failure\n- **Resume** (`run_from_branch`): Replaced `replace_worktree()` + `LocalSandbox::new(wt)` with `WorktreeSandbox::new(LocalSandbox(original_cwd), {skip_branch_creation: true})` + `initialize().await`\n- Deleted `setup_worktree()` function (logic absorbed into `WorktreeSandbox`)\n- Replaced `worktree_work_dir.is_some()` with `worktree_path.is_some()` for `meta_branch` and `git_checkpoint_enabled`", @@ -44,16 +48,17 @@ "internal.retry_count.simplify_opus": 1, "graph.goal": "# Unified WorktreeSandbox\n\n## Context\n\nWorktree management is currently split across two locations with duplicated logic:\n\n1. **Parallel branches** (`parallel.rs`): Inline git commands in `ParallelHandler::execute()`, a thin `WorktreeSandbox` decorator, and separate local/remote code paths\n2. **Top-level CLI run** (`run.rs`): A `setup_worktree()` function using synchronous git helpers, with the worktree path fed into a plain `LocalSandbox`\n\nThe goal is a single `WorktreeSandbox` type that wraps any `Arc`, manages the worktree lifecycle in `initialize()`/`cleanup()`, and eliminates the local/remote branching.\n\n## Plan\n\n### Step 1: Create `WorktreeSandbox` in fabro-sandbox\n\n**New file:** `lib/crates/fabro-sandbox/src/worktree.rs`\n\nDefine:\n\n```rust\npub enum WorktreeEvent {\n BranchCreated { branch: String, sha: String },\n WorktreeAdded { path: String, branch: String },\n WorktreeRemoved { path: String },\n Reset { sha: String },\n}\n\npub type WorktreeEventCallback = Arc;\n\npub struct WorktreeConfig {\n pub branch_name: String,\n pub base_sha: String,\n pub worktree_path: String,\n /// Skip branch creation and reset (for resume, where branch already exists).\n pub skip_branch_creation: bool,\n}\n\npub struct WorktreeSandbox {\n inner: Arc,\n config: WorktreeConfig,\n event_callback: Option,\n}\n```\n\n**Constructor + getters:** `new(inner, config)`, `set_event_callback()`, `branch_name()`, `base_sha()`, `worktree_path()`\n\n**`initialize()`:**\n1. If `!skip_branch_creation`: `git branch --force {branch_name} {base_sha}` via `inner.exec_command()`, emit `BranchCreated`\n2. `git worktree remove --force {path}` (best-effort), then `git worktree add {path} {branch}`, emit `WorktreeAdded`\n3. If `!skip_branch_creation`: `git reset --hard {base_sha}` in worktree dir, emit `Reset`\n\nDoes NOT call `inner.initialize()` — the inner sandbox's lifecycle is managed separately.\n\n**`cleanup()`:** `git worktree remove --force {path}`, emit `WorktreeRemoved`. Does NOT call `inner.cleanup()`.\n\n**`working_directory()`:** Returns `config.worktree_path`.\n\n**`exec_command()`:** Defaults `working_dir` to `config.worktree_path` when `None`, delegates to inner.\n\n**All other Sandbox methods:** Delegate to inner. Must be a manual `impl Sandbox` block (can't use `delegate_sandbox!` since it generates `initialize`/`cleanup`/`working_directory`/`exec_command` which we need to override).\n\nAll interpolated values in git commands use `shell_quote()`.\n\n### Step 2: Register module and re-exports\n\n- `lib/crates/fabro-sandbox/src/lib.rs`: Add `pub mod worktree;` and `pub use worktree::WorktreeSandbox;`\n- `lib/crates/fabro-agent/src/sandbox.rs`: Add re-export of `WorktreeSandbox`\n\n### Step 3: Unit tests for WorktreeSandbox\n\nIn `worktree.rs` `#[cfg(test)]` module, using `MockSandbox`:\n\n- `initialize()` issues correct git commands (branch, worktree remove, worktree add, reset) and emits events\n- `skip_branch_creation` skips branch + reset, only does worktree add\n- `cleanup()` issues `worktree remove` and emits `WorktreeRemoved`\n- `working_directory()` returns worktree path\n- `exec_command()` with `None` working_dir defaults to worktree path\n- `exec_command()` with explicit working_dir passes it through\n- `initialize()` propagates errors on non-zero exit\n\n**MockSandbox enhancement:** Add `captured_commands: Mutex>` field to `test_support.rs` to capture the sequence of `exec_command` calls (current `captured_command` only stores the last one). Append to vec in `exec_command()` impl.\n\n### Step 4: Refactor parallel.rs\n\n- **Remove** the private `WorktreeSandbox` struct (lines 28-126) and `use fabro_agent::LocalSandbox`\n- **Replace** the inline git setup loop (lines 361-450) with:\n - Construct `WorktreeConfig` with branch name, base SHA, worktree path\n - Create `WorktreeSandbox::new(Arc::clone(&services.sandbox), config)`\n - Wire event callback to bridge `WorktreeEvent` → `WorkflowRunEvent`\n - Call `initialize().await`\n- This eliminates the `if services.sandbox.is_remote()` branch (lines 442-449) — `WorktreeSandbox` works the same for any inner sandbox\n- **Cleanup loop** (lines 659-668): Keep calling `git_remove_worktree()` on the parent sandbox (the `WorktreeSandbox` Arc is consumed by the spawned task and dropped). Alternatively, could store the sandbox Arc in `BranchResult` and call `.cleanup()`, but the current approach is simpler.\n\n### Step 5: Refactor run.rs — new runs\n\nReplace `setup_worktree()` call (lines 830-845) + separate `LocalSandbox` construction with:\n\n```\nif workdir_strategy == LocalWorktree:\n base_sha = git::head_sha()\n branch_name = \"fabro/run/{run_id}\"\n inner = Arc::new(LocalSandbox::new(original_cwd))\n wt_sandbox = WorktreeSandbox::new(inner, WorktreeConfig { ... })\n wt_sandbox.set_event_callback(bridge to WorkflowRunEvent)\n wt_sandbox.initialize().await\n std::env::set_current_dir(&worktree_path) // stays in CLI, not in sandbox\n sandbox = Arc::new(wt_sandbox)\n // store base_sha, branch_name for RunConfig\n```\n\n**Delete** the `setup_worktree()` function (lines 1696-1714) — its logic is absorbed above.\n\n`std::env::set_current_dir()` stays in `run.rs` — it's a process-global side effect that belongs to the CLI.\n\n### Step 6: Refactor run.rs — resume (run_from_branch)\n\nReplace worktree re-attachment (lines 1810-1822) with:\n\n```\ninner = Arc::new(LocalSandbox::new(original_cwd))\nwt_sandbox = WorktreeSandbox::new(inner, WorktreeConfig {\n branch_name: run_branch,\n base_sha: base_sha.unwrap_or_default(),\n worktree_path: wt_str,\n skip_branch_creation: true, // branch already exists\n})\nwt_sandbox.initialize().await\nstd::env::set_current_dir(&wt)\n```\n\n### Step 7: Verify\n\n- `cargo build --workspace`\n- `cargo test --workspace`\n- `cargo clippy --workspace -- -D warnings`\n- Manual: `fabro run` with worktree mode enabled on a local workflow\n- Manual: `fabro run --run-branch` to test resume path\n\n## Files to modify\n\n| File | Change |\n|---|---|\n| `lib/crates/fabro-sandbox/src/worktree.rs` | **New** — WorktreeSandbox, WorktreeConfig, WorktreeEvent, impl Sandbox, tests |\n| `lib/crates/fabro-sandbox/src/lib.rs` | Add module + re-export |\n| `lib/crates/fabro-sandbox/src/test_support.rs` | Add `captured_commands: Mutex>` to MockSandbox |\n| `lib/crates/fabro-agent/src/sandbox.rs` | Add WorktreeSandbox re-export |\n| `lib/crates/fabro-workflows/src/handler/parallel.rs` | Remove old WorktreeSandbox, use new one |\n| `lib/crates/fabro-cli/src/commands/run.rs` | Replace setup_worktree + run_from_branch worktree logic |\n\n## Functions that become removable\n\n| Function | Location | Reason |\n|---|---|---|\n| `setup_worktree()` | `run.rs:1696` | Logic absorbed into WorktreeSandbox |\n| Old `WorktreeSandbox` struct | `parallel.rs:28-126` | Replaced by shared WorktreeSandbox |\n\nEngine git helpers (`git_add_worktree`, `git_remove_worktree`, etc. in `engine.rs`) stay — still used by parallel cleanup and potentially other callers.

Here's a summary of what was fixed:\n\n## Changes Made\n\n### Fix 1: Eliminated `worktree_event_callback` duplication (Code Reuse)\n\nThe function was defined identically in both `parallel.rs` and `run.rs`. Moved it as `EventEmitter::worktree_callback(self: Arc) -> WorktreeEventCallback` in `fabro-workflows/src/event.rs` — the natural home since it bridges `WorktreeEvent` (sandbox layer) → `WorkflowRunEvent` (workflows layer) via the emitter.\n\nBoth call sites now use `Arc::clone(&emitter).worktree_callback()`. The `WorktreeEvent` and `WorktreeEventCallback` imports were removed from `parallel.rs` and `run.rs`.\n\n### Fix 2: Removed no-op `git reset --hard` from `WorktreeSandbox::initialize()` (Efficiency)\n\nAfter `git branch --force {branch} {sha}` (step 1) and `git worktree add {path} {branch}` (step 3), the worktree is already checked out at exactly `sha` — `git reset --hard {sha}` was resetting a fresh worktree to the commit it was already at. This saved one git invocation (a process spawn locally, or an SSH round-trip on remote) per worktree initialization.\n\nRemoved `WorktreeEvent::Reset` from the enum since it was only emitted from the now-deleted reset step. `WorkflowRunEvent::GitReset` (the serialized protocol event) was left untouched for historical log compatibility.\n\nUpdated 3 affected tests: renamed the events assertion test, removed `initialize_reset_uses_worktree_path_as_working_dir`, and updated command-count assertions from 4 → 3.", "internal.retry_count.verify": 1, "thread.toolchain.current_node": "preflight_compile", + "response.fixup": "All tests pass and clippy is clean.

Git refuses to force-update a branch that is currently checked out by an existing worktree. When a previous run (or parallel test) left a stale worktree at the same path with the same branch name, the `branch --force` command would exit 128. + +**Fix**: Move the best-effort `git worktree remove --force {path}` to **before** `git branch --force {branch} {sha}`. This frees the branch from any stale worktree registration first, allowing the force-update to succeed. + +The updated sequence in `initialize()`: +1.
