Stacked on #341.

Add a fullscreen workspace inspector without redesigning the existing open_workspace card: a hover/focus fullscreen affordance opens a React surface with Activity and Changes views. Activity lazily exposes raw tool inputs/results, while Changes supports review checkpoints, working-tree diffs, branch changes, and exact ref comparisons through one shared diff model.

The inspector uses TanStack Query and TanStack Router, keeps its MCP data tools app-only so inspection cannot recursively journal itself, and reuses the existing Pierre diff renderer.

Greptile Summary

Summary

  • Workspace diff comparisons can return sibling files outside a selected subdirectory workspace.
  • Fullscreen workspace inspection is reset by ordinary host layout updates.
  • Historical review activity is silently incomplete when a review contains more than 250 preceding calls.

These failures must be addressed before merging.

Confidence Score: 1/5

Unsafe to merge until workspace diff isolation, fullscreen state preservation, and complete review activity retrieval are fixed.

Three independently reproduced failures affect workspace data boundaries, user investigation continuity, and historical activity accuracy; one exposes files outside the selected workspace.

Files Needing Attention: src/workspace-diff.ts must scope Git operations to the workspace root; src/ui/workspace-app.tsx must preserve the mounted fullscreen inspector on non-display updates; src/workspace-activity-service.ts must continue loading activity until the review group boundary.

Security Review

Workspace diff comparisons disclose repository-root and sibling-file changes outside the selected subdirectory workspace in working-tree, branch, and explicit comparison views.

Comments Outside Diff (3)

  1. General comment

    P1 Workspace diff scopes are not limited to the workspace root

    • Bug
      • For a workspace rooted at packages/inside, changes to repository-root outside.txt are returned by readWorkspaceDiff. The working-tree scope returned outside.txt as its sole file; branch and explicit compare scopes returned both outside.txt and packages/inside/inside.txt. Each response patch also contained outside.txt.
    • Cause
      • At src/workspace-diff.ts:44-49, the implementation resolves gitRoot and calls createWorkingTreeSnapshot(gitRoot, head) and readReviewBetween(gitRoot, head, snapshot). The branch and compare flows at lines 52-71 similarly call readReviewBetween against the repository root. Neither helper invocation supplies a pathspec or filters resulting paths to workspace.root.
    • Fix
      • Constrain snapshot creation and Git diff commands to the workspace path relative to gitRoot (for example, pass -- <relative-workspace-path> to git add and both git diff commands), and add regression tests for working-tree, branch, and compare scopes with a subdirectory-rooted workspace.

  2. General comment

    P1 Fullscreen workspace inspector resets on non-display host-context updates

    • Bug
      • While the fullscreen inspector was on Changes with Compare refs selected, a safe-area update reset it to the default Activity route and removed the selected compare query/UI state.
    • Cause
      • src/ui/workspace-app.tsx:109-112 unconditionally calls render() whenever the merged context remains fullscreen and the card is open_workspace; render() begins with unmountInspector(), recreating the inspector and its memory router.
    • Fix
      • Remove or narrow the fullscreen open_workspace render branch so only an actual display-mode change remounts the inspector. Apply safe-area/style updates in place and preserve the mounted inspector/router.

  3. General comment

    P1 Review-group lookup truncates continuous histories beyond 250 calls

    • Bug
      • For a review boundary preceded by 300 contiguous relevant calls, findReviewGroup returned 251 calls (IDs 51-301) and silently omitted the oldest 50 calls (IDs 1-50). Its startedAt was reconstructed as 2026-09-10T00:00:50.000Z, 50 seconds after the true beginning of the uninterrupted group.
    • Cause
      • At src/workspace-activity-service.ts:34-40, the method limits the preceding query to DEFAULT_ACTIVITY_CALL_LIMIT (250) before passing it to the grouping function. No pagination or boundary-aware continuation is performed, so a group that began before the fetched page is indistinguishable from one that began at the page edge.
    • Fix
      • Fetch preceding summaries in pages until reaching a group boundary (a conversation change or a time gap), then group the complete relevant run; alternatively add a store query that retrieves the complete preceding group using the grouping boundary predicates.

P1 security Keep diffs inside workspace

If a workspace is rooted in a subdirectory of a Git repository, this resolves comparisons to the repository root and returns repository-wide patches. The workspace inspector can therefore expose sibling files outside the selected workspace through working-tree, branch, and explicit comparison views. Restrict snapshot creation and Git comparisons to the workspace-relative path.

How this was verified: A subdirectory workspace returned the repository-root outside.txt change in working-tree, branch, and explicit comparison results.

Knowledge Base Used: MCP server and workspace API

Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Artifacts

Evidence from the check

  • Creates a temporary Git repository with changes inside and outside a subdirectory workspace, then invokes every affected diff scope; it provides the executable reproduction.

Command output from the check

  • Runs `git cat-file` against the parent of the commit that introduced workspace-diff.ts and shows exit code 128 because the endpoint did not yet exist; it establishes that prior endpoint behavior is unavailable.

Command output from the check

  • Runs the uploaded TypeScript repro with exit code 0 and shows outside.txt in files and patches for working-tree, branch, and compare scopes; it confirms repository-wide leakage.

P1 Preserve fullscreen inspector state

A non-display host-context update while the workspace inspector is fullscreen calls render(), which unmounts and recreates the inspector. A safe-area update reset an inspector that was on Changes with Compare refs selected back to Activity, losing its route, selected comparison, and loaded state. Apply these context updates without rebuilding the inspector.

Knowledge Base Used: Workspace web application

Artifacts

Evidence from the check

  • The uploaded harness mounts a simulated MCP fullscreen inspector, changes it to Changes and Compare refs, sends one safe-area update, and records lifecycle state; it reproduces the reset.

Command output from the check

  • The uploaded command output records exit code 0 and shows Changes/compare before the safe-area update, then Activity afterward with safe-area padding applied; it confirms state loss.

Evidence from the check

  • The uploaded structured result records the removed and added workspace inspector host node and the route reset after the single safe-area update; it confirms a remount.

▶ Recording of the check

  • The uploaded Chromium recording shows the inspector navigated to Changes with Compare refs selected before any context update; it establishes the preserved state baseline.

Poster frame of fullscreen inspector before update

  • The uploaded poster frame previews the fullscreen inspector in its Changes and Compare refs state; it establishes the baseline.

▶ Recording of the check

  • The uploaded Chromium recording shows the same inspector after one non-display safe-area update; it returns to Activity and demonstrates the reset.

Poster frame of fullscreen inspector after safe-area update

  • The uploaded poster frame previews the inspector after the safe-area update; it shows the reset to Activity.

P1 Load complete review activity

Review lookup fetches only 250 calls preceding the review boundary before rebuilding the group. A continuous review with 300 preceding calls returned only calls 51–301 and reconstructed its start time 50 seconds late, silently omitting the oldest activity. Continue fetching until a group boundary is reached, or report that the result was truncated.

Artifacts

Command output from the check

  • Captured the inspected changed-code lines before executing the reproduction; it shows the fixed 250-call query limit that causes truncation.

Evidence from the check

  • Captured the authored TypeScript script that creates 300 relevant preceding calls and invokes findReviewGroup exactly once; it provides the executable reproduction.

Command output from the check

  • Captured output from the executed SQLite reproduction; it shows IDs 1-50 omitted and an incorrect group start after the 250-call cutoff.

Command output from the check

  • Captured the repository TypeScript typecheck after the reproduction; it completed successfully.

Do not fall back to groups[0] for an invalid activity selector.

When /activity includes a missing review or group, selected falls back to the latest activity group. The view can display activity for a different review or group. Return a not-found state for an unmatched selector, and use groups[0] only when no selector is provided.

Preserve incomplete /changes scopes

When scope=review lacks review, or scope=compare lacks from or to, ChangesView falls through to the latest review or working-tree scope. workspaceDiffQuery then renders a different diff than the route requested. Keep the requested scope in a validation/not-found state and do not derive a fallback diff for it.

Keep the fullscreen action visible on touch devices.

The button becomes visible only through hover or keyboard focus. Touch input generally provides neither state before activation. A sighted touch user therefore cannot discover the fullscreen action.

Add a non-hover media rule that keeps the action visible.

Do not remount the inspector for every host-context event.

This branch calls render() for resize and unrelated context updates. render() unmounts the current inspector and creates a new router and query client. This resets the selected route, expanded calls, and cached queries.

Only remount when an inspector-consumed value changes, or add an update lifecycle method that preserves React state.

As per coding guidelines, use explicit lifecycle and preserve inspectable state. <coding_guidelines>

Gate the fullscreen inspector on serverTools.

displayMode and serverTools are independent host capabilities. A host can report fullscreen without supporting server-tool calls. This branch then mounts renderWorkspaceInspector(card), whose queries call app.callServerTool(...) and fail on that host. Reuse canOpenWorkspaceInspector(card) here; otherwise keep the inline card or show an unsupported-host state.

Order the single-row review lookup by newest call.

workspaceToolCalls.reviewRef has a non-unique index. Multiple calls can share a reviewRef, but findCallSummaryByReviewRef calls .get() without ordering. findReviewGroup then excludes calls newer than the selected boundary.

       .where(
         and(
           eq(workspaceToolCalls.workspaceSessionId, workspaceId),
           eq(workspaceToolCalls.reviewRef, reviewRef),
         ),
       )
+      .orderBy(desc(workspaceToolCalls.id))
       .get();

CWE: CWE-200 — Exposure of Sensitive Information to an Unauthorized Actor

Keep all diff operations inside workspace.root.

openCheckoutWorkspace permits a workspace below the Git repository root. readWorkspaceDiff then resolves that workspace to gitRoot, snapshots the entire repository, and runs unscoped diffs. This can expose sibling changes through get_workspace_diff. Review checkpoints use the same unscoped repository path.

Pass a workspace-relative pathspec through snapshot and diff operations. Add a regression test with changes inside and outside a nested workspace.

In `@src/workspace-diff.ts` at line 38, Scope readWorkspaceDiff and its
review-checkpoint operations to workspace.root rather than the repository root.
Derive a workspace-relative pathspec and pass it through snapshot creation and
all diff operations, while preserving existing behavior for workspaces at the
repository root. Add a regression test covering changes both inside and outside
a nested workspace, verifying only inside changes are returned.
