Summary

  • Add a stack History tab backed by the stack-scoped history API (list, load more, commit detail with shared unified-diff rendering).
  • Surface outstanding drafts via the existing Changes tab count plus a header badge that links to Changes (no sidebar noise, no extra draft queries).
  • Cover list/empty/load-more/detail, draft badge on/off, g c shortcut, mobile, and axe in Playwright.

Test plan

  • Open a fetched stack → History shows commits touching that stack (message, short SHA, author, time, files)
  • Empty history copy: “No commits touching this stack were found.”
  • Load more when nextCursor is present; open a commit and inspect scoped diffs
  • Save a draft → Changes tab count + header badge appear; discard → both gone
  • g then c opens Changes when focus is outside inputs/editors
  • pnpm check && pnpm build && E2E_GIT_REMOTE=… E2E_STACK_ROOT=… pnpm test:e2e

Made with Cursor

Summary by CodeRabbit

  • New Features
    • Added a History tab for viewing commits that affected a stack at its last fetched snapshot, with expandable file changes and unified diffs. Browse additional commits and see when history or file lists are limited.
    • When a stack has drafts, its header shows a Changes link with the draft count. Use the g then c shortcut to open Changes.
  • Documentation
    • Updated the guides and product status information to describe stack history, draft commits, and safe pushes.

Expose stack-scoped Git history in the UI and surface draft counts on the Changes tab and stack header so outstanding work is easy to find.

📝 Walkthrough

Walkthrough

The stack UI adds a History page for stack-scoped commits, paginated commit details, and unified diffs. Stack tabs and headers provide History navigation and draft-count links to Changes.

Changes

Stack history and draft navigation

Layer / File(s) Summary
History page and commit details
src/app/w/[workspaceId]/stacks/[stackId]/history/page.tsx, src/ui/source/history-view.tsx, src/app/styles/source.css, tests/e2e/source.spec.ts, docs/getting-started.md
The History page loads commit pages and expandable details, displays file statuses and diffs, and handles loading, empty, and error states. End-to-end tests cover history loading, pagination, and empty history. The getting-started guide describes the History tab.
Shared unified diff rendering
src/ui/source/unified-diff.tsx, src/ui/source/changes-view.tsx
The shared UnifiedDiff component renders diff hunks for History and Changes. The Changes view replaces its inline diff renderer with this component.
History tab and draft navigation
src/ui/source/stack-tabs.tsx, src/app/w/[workspaceId]/stacks/[stackId]/layout.tsx, src/app/styles/source.css, tests/e2e/source.spec.ts, docs/UX.md, docs/index.md
Stack tabs include History and support the g-then-c shortcut to Changes. When drafts exist, the stack header links to Changes and displays the draft count. The draft badge styling, navigation tests, and UX and status documentation are updated.

Merge Risk: ⚪ Minimal · up to 12612

No actionable merge-blocking issue is established; the change is mergeable after the planned checks.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d7663

The History screen reuses existing authenticated, stack-scoped endpoints and adds no write authority. No new security boundary bypass was identified. Navigation-time state handling and some supporting surfaces remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The added exposure is browser presentation of metadata and permitted historical diffs for a resolved stack. Repository contributors can influence displayed commit messages, author fields, paths, and diff text. The inspected new flow does not grant repository writes, credential access, or deployment authority.

Security Findings and Attack Paths

  • observed — Repository-controlled display strings and diff lines enter ordinary React text children. The shared diff renderer has no HTML-injection sink, navigation behavior, or authority-bearing callbacks. This rejects an executable-content attack path through the inspected rendering change.

Trust Boundaries and Controls

  • observed — Server-side detail protection remains authoritative. Secret-path and unsupported-path checks, symlink and submodule locks, blob-size limits, binary detection, and diff limits determine whether hunks are returned. The new UI displays lock explanations rather than retrieving protected contents through another path.
  • observed — Cursors are validated against repository, root, page size, and snapshot ancestry. Detail requests require a full commit SHA, fetched-history ancestry, and a commit touching the resolved scope. These existing checks prevent the new caller from selecting arbitrary repository scope through cursor or SHA inputs.

Resilience and Maintainability Implications

  • observed — Initial-list and detail effects ignore responses after cleanup, and the loading button blocks ordinary repeated pagination activation. Cursor append lacks equivalent cancellation or generation checking. If navigation retains HistoryView, a previous stack's response could contaminate presentation state; that lifecycle remains unverified and is not evidence of a server authorization bypass.

Hardening Proposals

  • proposed — Key or reset History state by API base and generation-check pagination responses. Clear detail state when its identity changes. This would preserve stack-context integrity even if navigation retains the component during an in-flight request.

getting-started documentation, placing it between Changes and Settings to match
the tab order described in the History section.

Review comments at @src/app/w/[workspaceId]/stacks/[stackId]/history/page.tsx:
- Around line 12-14: Wrap the `stacks.get` lookup in the history page with
`orNotFound` so a missing stack renders as not found rather than reaching the
error boundary. Reuse the `orNotFound` helper from the session utilities and add
its import as needed.
