…lete and verified. ## Status Implemented per-turn checkpoint commits + finalize-time squash in `build_sdd_loop_step`/`build_finalize_step` (`src/work_item_pipeline.rs`), building on #191's `worktree_path` threading: - **`crates/flare-git-core/src/worktree.rs`**: added `commit_uncommitted_at` (path-based variant of `commit_uncommitted`, with a `no_verify` flag), `head_sha`, and `squash_since` (`git reset --soft`). `commit_uncommitted` now delegates to `commit_uncommitted_at`. Thin wrappers added in `src/worktree.rs`. - **`WorkItemData`**: added `checkpoint_base_sha: Option<String>`. - **`build_sdd_loop_step`**: role dispatch now also returns `is_implementer_turn` (true only for non-review-only implementer/fix dispatches, never for judge/reviewer/analyst turns). After a successful implementer-turn `send()`, `checkpoint_implementer_turn` commits with `--no-verify` (skipping the LOC-freeze gate per open question #1) and lazily captures the pre-checkpoint HEAD sha. - **`build_finalize_step`**: right before the existing `item_done` call, squashes every checkpoint commit back to `checkpoint_base_sha` via `squash_since`, so `item_done`'s own `commit_uncommitted` (which does run the LOC-freeze pre-commit hook) evaluates the whole run's diff as one commit. `.take()` on the sha prevents a step retry from double-squashing. - Commit message convention: `wip(sdd-loop): task {id} checkpoint` (open question #2) — disposable, just grep/reflog-identifiable. **One real bug caught and fixed during implementation**: my first draft fell back to the ambient process cwd when `worktree_path` was empty (mirroring `real_agent_send_hook`'s dispatch fallback). Running the test suite actually committed my own uncommitted working-tree changes into this session's real git history, since the test harness has no `worktree_path` set and ambient cwd was this repo. I reset that commit (`git reset --soft`, verified only my own 3 in-progress files were affected) and changed the checkpoint function to no-op entirely when `worktree_path` is empty — a `git commit` has no safe ambient fallback, unlike read-only agent dispatch. Added a regression test (`checkpoint_implementer_turn_is_a_noop_without_a_worktree_path`) guarding this specifically. **Tests added**: 4 in `flare-git-core/src/worktree_tests.rs` (`commit_uncommitted_at`, `head_sha` ×2, `squash_since`), 2 in `work_item_pipeline/tests.rs` (no-op guard, and an end-to-end commit+squash test against a real claimed worktree). All pass — 207/207 (flare-git-core), 83/83 (work_item_pipeline module, 2 pre-existing unrelated ignores). **Verification**: full builds clean, `scripts/loc-gate.sh` passes on every file I touched (had to trim doc comments twice to stay under work_item_pipeline.rs's 1500-line limit — now 1498), clippy shows no new warnings in touched files. One pre-existing repo-wide LOC-gate failure in `src/mcp_server/tests/item_tests.rs` (untouched by me, and per the gate script's own comments, not wired into CI) — not in scope. No concerns beyond the above; nothing committed, per instructions this is left for your review.

Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to If checkpoint squashing fails during finalization, the workflow can still complete with intermediate WIP commits left in the branch and without validating the entire run as one final commit.

Do not continue finalization after squash_since fails.
Line 828 removes checkpoint_base_sha before Line 832 runs the squash. If squash_since fails, this code logs the error and calls item_done. The retained checkpoint commits used --no-verify, and the final commit can then contain only changes after the last checkpoint. This bypasses the intended whole-run LOC-gate evaluation and leaves WIP commits in the branch.
Restore checkpoint_base_sha on failure and return WorkflowError::StepFailed before item_done.
Proposed fix
- if let Some(base_sha) = ctx.data.checkpoint_base_sha.take()
+ if let Some(base_sha) = ctx.data.checkpoint_base_sha.take()
&& !ctx.data.worktree_path.is_empty()
{
let worktree_path = std::path::PathBuf::from(&ctx.data.worktree_path);
if let Err(e) = crate::worktree::squash_since(&worktree_path, &base_sha) {
- eprintln!("finalize: squashing sdd_loop checkpoint commits for item {item_id} failed: {e}");
+ ctx.data.checkpoint_base_sha = Some(base_sha);
+ return Err(WorkflowError::StepFailed {
+ step_id: StepId::new("finalize"),
+ message: format!("could not squash checkpoint commits: {e}"),
+ });
