Preserve the patch when metadata parsing fails.
parseReviewFiles throws at Line 175. reviewChanges then fails at Line 126 before it returns patch to ReviewPayload.
src/ui/review-payload.tsx cannot display its parser-error status on this path because it receives no payload. Return the patch with empty metadata and an explicit parse-error result. Preserve the error for the UI.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Set an internal Git identity for snapshot commits.
git commit-tree at Line 279 requires author and committer identity. A fresh git init can have no configured identity.
src/review-checkpoints.test.ts configures user.email and user.name for its unborn repository. The test therefore does not cover this valid workspace state. initializeWorkspace records a diagnostic and reviewChanges fails instead of reviewing the workspace.
Pass fixed internal author and committer environment variables only to the snapshot commit-tree command. Do not modify the user's Git configuration.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Greptile SummaryThe PR hardens review checkpoints by supporting unborn repositories, limiting snapshots and diffs to nested workspace roots, parsing metadata from renderable patches, and surfacing patch-parser failures in the UI.
Confidence Score: 4/5The large-diff regression should be fixed before merging because reviews that previously worked can now fail at the reduced output limit. The checkpoint behavior is otherwise coherently hardened and covered, but every review now buffers its complete textual patch under a 10,000,000-byte ceiling, making sufficiently large change sets impossible to review.

| Filename | Overview |
|---|---|
| src/review-checkpoints.ts | Adds workspace-scoped, parentless snapshots and parser-backed metadata, but lowers the diff output ceiling enough to reject previously supported large reviews. |
| src/git.ts | Removes the no-HEAD eligibility rejection so the checkpoint manager can support unborn repositories. |
| src/review-checkpoints.test.ts | Adds focused coverage for nested workspace isolation, binary rendering, pure renames, and unborn repositories. |
| src/ui/review-payload.tsx | Converts patch parser exceptions into a stable user-visible error state. |

There was a problem hiding this comment.
When a rendered review patch exceeds 10,000,000 bytes, the changed git diff command rejects instead of returning the review, causing change sets that fit under the previous 50 MiB limit to become unreviewable.

show_changescurrently snapshots from the repository root, couples snapshot commits toHEAD, performs a second diff for stats, and can hand fragile binary/external-diff output directly to the review widget.This keeps Git checkpoints as the source of truth but tightens that implementation: snapshots and displayed paths are scoped to the DevSpace workspace, checkpoint commits are parentless and work before the first Git commit, review diffs disable external/textconv drivers and binary patch payloads, and the server validates the same patch the UI renders. File stats now come from that parsed patch instead of a second
git diff --numstattraversal.This is the bottom PR of the two-PR review experiment; it is independently useful without the journal layer.
