* fix: scope multi-repo file editor open/save to the right repo
The editor open/save/sync/delete chain dropped the repository_name in
multi-repo task workspaces, so the backend resolved paths against the
bare task root and failed with "file not found". Thread the repo
subpath through openFile, save, sync, and delete, and store it on
FileEditorState.
* fix: pass repo from diff Edit button to multi-repo file editor
The diff/changes "Edit" button opened files without their repository
scope, so multi-repo files resolved against the bare task root and
failed with "file not found". Thread repository_name through the diff
and review toolbars into onOpenFile.
* fix: preserve repo across tab restore and stale syncs
Address review feedback: persisted file tabs dropped the repo subpath,
so a multi-repo file reopened against the bare task root after a browser
refresh. Persist and restore `repo` on StoredFileTab. Also guard the
workspace sync against a tab being swapped to a different repo mid-fetch,
and widen the remaining onOpenFile type declarations to carry repo.
* fix: thread repo into editor panel fallback fetch
Address review feedback: FileEditorPanel's useFileLoader fallback fetch
(triggered when the open-files map is transiently empty, e.g. after a
session switch) called requestFileContent without the repo subpath,
re-introducing the multi-repo "file not found" failure. Record repo on
the panel params and forward it through useFileLoader. Also assert the
full restored-tab shape in the local-storage round-trip test.
* fix: guard editor fetches against stale session/repo races
Address review feedback: file open and the panel fallback fetch could
apply a late response after the user navigated away. openFile now drops
the result if the active session changed mid-fetch (via fetchFileEditorState),
and the panel loader keys its in-flight guard by session+path+repo so a
changed target re-fetches and stale responses are discarded.
* feat(backend): add support for fetching file content at git ref
Add GetFileContentAtRef method to WorkspaceTracker for retrieving file content
at specific git refs (branches, commits, HEAD). This enables diff expansion by
fetching old file versions without checking out.
Changes:
- Extract maxFileSize constant to package level (10MB)
- Add GetFileContentAtRef to workspace_files.go using git show
- Add workspace.file.get_at_ref WebSocket action and handler
- Add agentctl client method for the new endpoint
- Register handler in workspace file handlers

* feat(web): add diff expansion support for code review
Add lazy-loaded diff expansion to show more context in code reviews. When expansion
is enabled, users can expand hunks to see more surrounding code by clicking expand
buttons. Full file content is fetched on-demand via WebSocket.
Changes:
- Add useExpandableDiff hook for lazy-loading old/new file content
- Add requestFileContentAtRef to workspace-files.ts
- Integrate expansion into diff viewer components
- Add enableExpansion and baseRef props to DiffViewer
- Auto-load expansion content when enabled
- Pass expansion state through diff viewer hierarchy

* fix(web): gracefully handle expansion props for Monaco diff viewer
Monaco diff viewer has built-in expansion that doesn't require fetching
old file content. Strip pierre-diffs-only expansion props (enableExpansion,
baseRef) when Monaco is selected to avoid passing unsupported props.
This ensures the feature works correctly regardless of which diff viewer
the user selects in settings.

* feat(backend): add diff expansion e2e scenario and fix unstaged diff base ref
- Add scenarioDiffExpansionSetup mock-agent scenario that creates a
200-line file, commits it, then modifies lines 50 and 150 to produce
a two-hunk uncommitted diff for testing diff expansion in the UI
- Add workspace_file_handlers for workspace.file.get_at_ref WS action
- Fix enrichWithDiffData to always diff against HEAD for unstaged/staged
content so locally committed files show correct diffs
- Add unit tests for GetFileContentAtRef (6 sub-tests)
* feat(web): add diff expansion UI and e2e test
- Wire useExpandableDiff hook into FileDiffViewer and ReviewDiffList
with enableExpansion and baseRef props
- Gracefully handle expansion props for Monaco diff viewer fallback
- Add e2e Playwright test for diff expansion between hunks
* fix(web): fix diff expansion by correcting hunk separators and line splitting
Three bugs prevented @pierre/diffs expand buttons from rendering:
- hunkSeparators was "simple" (no expand UI); changed to "line-info" when expansion enabled
- expandUnchanged:true showed all lines expanded (no separators); removed the option
- .split("\n") stripped trailing newlines; now uses SPLIT_WITH_NEWLINES regex to match library
* feat(web): add editor provider settings UI
Add an "Editor Providers" section to the Editors settings page with
Select dropdowns for each configurable context (Code Editor, Diff Viewer,
Chat Code Blocks, Chat Diff Blocks). Reads from and writes to the
existing localStorage-backed editor resolver store. Changes apply
immediately without requiring a save action.
* test(web): add e2e tests for editor provider settings
Verify that the editor provider dropdowns render with correct defaults,
update on selection, and persist changes across page reloads via
localStorage.
* feat(web): add expand/collapse unchanged regions toggle to diff toolbar
Refactor diff header toolbar into composable ToolbarButtons component and
add a toggle button to expand or collapse unchanged regions in both
Pierre Diffs and Monaco diff viewers. Pass enableExpansion through to
Monaco to control hideUnchangedRegions.
* fix(web): handle deleted files in diff expansion
Treat "file not found" / "no such file" errors as empty content instead
of throwing, so diff expansion works correctly for deleted files.
* chore(web): add diff expansion debug e2e helpers
* test(web): split diff expansion tests by provider (Pierre Diffs + Monaco)
Restructure diff-expansion e2e tests into two describe blocks, one per
diff viewer provider. Each block sets the provider via localStorage
before navigation and verifies the correct viewer renders:
- Pierre Diffs: checks for diffs-container element and shadow DOM
expand buttons between hunks
- Monaco: checks for .monaco-diff-viewer wrapper and the built-in
hideUnchangedRegions widget with "Show Unchanged Region" link
Both suites verify that clicking expand reveals collapsed middle lines.
* fix(web): fix Pierre Diffs expand button selectors in e2e tests
Use shadow DOM data attributes ([data-expand-button], [data-expand-up])
instead of XPath parent traversal which doesn't work inside shadow DOM.
Wait for expand buttons to load asynchronously before clicking.
* fix(e2e): make diff-expansion-setup scenario idempotent
The mock-agent scenario now removes and re-commits the test file before
each run, so subsequent tests in the same repo don't fail with "git
commit failed" when the file already exists. Also increase test timeouts
to match other heavy e2e tests.
* refactor(web): remove editor provider settings UI, enable expand-all in review
Remove the editor provider switching UI and its tests — Monaco's diff
expansion doesn't work and exposing provider switching adds confusion.
Show Pierre Diffs header toolbar in the review panel (remove hideHeader)
so the expand-all button is accessible. Add e2e test for expand-all.
* style(web): fix prettier formatting and lint warnings
Run prettier on files with formatting drift. Extract ToolbarBtn helper
in diff-header-toolbar to stay within max-lines-per-function limit.
Consolidate useMonacoDiffViewerState to reduce line count.
* chore(web): remove debug scaffolding, revert Monaco changes, drop stray console.log
Revert Monaco diff-viewer-toolbar and monaco-diff-viewer to main
(expansion not functional with Monaco). Remove debug-expansion
screenshot scripts and spec. Strip console.log from commit-detail-panel.
Strip enableExpansion from Monaco path in diff-viewer-resolver.
* fix(web): use commit-relative base ref for diff expansion
Use `${commitSha}^` instead of hardcoded `HEAD~1` so expansion fetches
the correct old content when viewing non-HEAD commits.
* fix(web,backend): address CodeRabbit review feedback
- Add aria-label to icon-only toolbar buttons for screen reader access
- Guard auto-load expansion effect against error state to prevent retry
loops when WebSocket fetch fails
- Invalidate expansion cache on file/ref change with request versioning
to prevent stale content
- Preflight blob size with git cat-file -s before git show to avoid
memory spikes on large files
