Merge scope

Base: origin/main at 71a2c0552d23d5de38c1e5592a7f5060054ea2c4. No open upstream-sync PR existed when this run started. This PR merges the pinned upstream commit with --no-ff; no rebase, cherry-pick, or changes to another sync branch.

Upstream range: 71a2c0552d23d5de38c1e5592a7f5060054ea2c4..07f7f976097b56450364fe136aac9253f4f7d8e1.

Conflict resolution and fork preservation

• Combined upstream linked-environment, GitHub sign-in, local-server, snooze, and thread-origin contracts with the fork's integration contexts, drafts, checkouts, providers, tabs, groups, and permissions. Preserved upstream history; all resolution changes are part of the merge commit.
• Retained composer account/model selectors, integration pickers and previews, context imports, drafts, queue controls, quick-message submission, citations, rollback actions, and expanded tool panels while adopting upstream linked-machine chips and tool-diff actions.
• Ported project-folder/F6 navigation onto the fork's shared sidebar. Removed the uncalled legacy sidebar component, retained shared fork menus/tabs/groups/hiding, and reconciled docs/fork-differences.md to describe the project-folder view.
• Kept mobile integration/agent/tab controls and Devin account usage within upstream's wider Usage layout and new navigation. Updated imports where upstream extracted UI helpers.
• Combined server peer-link services and fork integration services. Retained linked-checkout turn prompts, subscription-limit guards, update pause behavior, delegated worktree setup, terminal Python activation, and fork HTTP/MCP entry points. Migrated fork settings/task reads to the first subscription snapshot after upstream removed their unary RPCs.
• Retained the fork's live usage fields and transcript snapshot loading while accepting deletion of unused legacy runtime-event and compatibility schemas. Ported upstream linked-PR text ranking into the fork's source-control definitions, preserving authority-aware deduplication.

The initial ancestry comparison was 564 fork-only / 170 upstream-only commits. The final pre-push refresh found no open sync PRs, an unchanged origin/main base, and all 170 pinned upstream commits still missing. The fork-only commit log and all source links in docs/fork-differences.md were reviewed; no fork feature section was removed as adopted upstream.

Split/deletion audit

• ProviderTurnStartService.ts: a14388d26d subscription guard remains; d42edbbfd4 linked-checkout prompt and additionalDirectories moved into upstream's earlier turn-start location; 82d8dce7c3 / 38ebd51017 control/import paths remain called.
• ProjectionStore.ts: upstream's uncalled memory layer was removed; the SQL implementation retains 11058b7fd1 automation/scheduled-task identity, 0e8c7f3d94 move blockers, d42edbbfd4 linked checkouts, and e483cb0740 hidden/group fields.
• providerRuntime.ts: 7392c39657, b2c48292d2, and e2afc1f2f6 audited; live usage fields remain, unused legacy event schemas have no callers, and the still-used runtime turn-status type remains exported.
• Transcript loading (a02770d743) retains loadFullThreadSnapshot and its export-dialog caller; linked numeric PR matching (59754ba356) retains the fork's relocated implementation and tests alongside upstream text-search ranking.

Web split/deletion audit

Upstream deletes the uncalled LegacySidebar.tsx and the twelve-line composer editor re-export. The fork's live sidebar already lives in Sidebar.tsx and sidebar/*; its richer composer wrapper remains called by ChatComposer and QuickMessagePanel. Fork commits touching those deleted upstream files since the shared merge base were checked against the surviving callers:

• ad4e011e7b: citation comment destinations remain in ComposerPromptEditor, AssistantCitationChip, and CitationDestinationPicker.
• c460d20a11: the previous sync's restored fork behavior remains on the active composer/sidebar paths; the dead legacy component is removed.
• 931f1663f0: grouped Link actions remain in threadActionMenu.logic and sidebar/integrationLinks.
• 51201bd32a: Discord actions remain in integration palette/composer handlers and the shared sidebar Link submenu.
• c673040d0b: Granola remains in the integration context/picker handlers and Link submenu.
• 82d8dce7c3: agent controls and fork workflows remain in shared menus, timeline rewind, inspector, and command palette.
• 1cf0291525: thread groups remain in useSidebarOrganization, partitionSidebarThreads, menu actions, and search.
• c1c87684f5: restart-session remains in the shared menu builder and sidebar action handler.
• 6ea52f7081: Import conversation remains in CommandPalette with its import dialog caller.
• 76c1f10c90: split-view actions remain in useChatViewSplitPane, shared sidebar menus, and CommandPalette.
• bb287bac98: Linear link/status and picker actions remain in shared integration handlers and menus.
• a02770d743: Export transcript remains in shared sidebar menus and CommandPalette.
• 8d76e707b7: New tab and Close tab remain in shared sidebar/header menus and useThreadTabActions.
• 86839d1ff4: grouped rows retain threadTabGroupTarget/recency selection and the selected tab's title/model/details.
• 7f2ef1d689: workspace sharing, hidden child tabs, group rows, and tab navigation remain in shared tab hooks.

The recent fork extractions (701865a789, 21c861c16c, fcaed53677, e440ab7fe6, 16d5a7f202, 9eaf2ec73a, 2494e44278) remain called from the active sidebar, chat view, composer, context preview, and palette; upstream additions were ported onto these components instead of reinstating duplicate implementations. Upstream's model reconciliation now starts from appInit; queued-edit uploads keep the fork's shared attachment uploader, and persisted multi-project scopes retain both the fork's exported setter and upstream's older-client field.

Verification

• Installed the merged lockfile with vp i using the repository's local Vite+ 1.4.0 (the ambient global CLI is older).
• Focused typechecks passed for contracts, shared, client-runtime, source-control definitions, Cursor, desktop, server, web, and mobile. A final integrated server/web/mobile pass also passed.
• Shared/contracts/Cursor/source-control logic: 208 tests passed across nine files. Desktop activation/broker: 7 passed. Web logic: 332 passed. Mobile logic: 150 passed.
• Server focused regressions passed for thread launch, CLI settings/schedules/integrations, MCP metadata/budget/integration/cancel/rollback/spawn, projection/wire behavior, setup runners, update pause, auth/cloud/providers, and thread management. The launch/CLI batch passed 107 tests, projection/MCP batch 91, final metadata/update/thread-management batch 66, and provider registry rerun 50. Five conflict-relevant Claude/Codex adapter cases passed. An initially broader adapter-file run stalled and was stopped; only the targeted adapter coverage is claimed.
• Final linked-environment/agent-access fixture suite: 53 tests passed across four files. The local target.projectId rejection and three fork cross-project worktree regressions also passed; the guard preserves the distinction from the fork's top-level projectId.
• Explicit-file formatting/lint checks passed for resolved/shared changes, 221 server files, 81 web files, and 42 mobile files (plus focused final rechecks).
• MCP worktree-delegation eval dry-run passed. Paid model eval was unavailable because ANTHROPIC_API_KEY is not configured.
• Resolved files pass whitespace checks. The full staged whitespace check flags only required blank context lines in upstream's unchanged expo-sharing patch; the staged check excluding that patch passes.

No repo-wide checks, browser tests, computer automation, native UI verification, release builds, or releases were run. check:changed was replaced by the focused checks above because its sync-wide affected set invokes browser tests, which this run explicitly prohibits. No before/after UI captures were taken for the same reason.

Follow-up regression verification on the exact merged PR head 58b1e92c3abe511e5eaa330ca6f81de401552a32 (not current main):

• Ran vp run check:changed 71a2c0552d23d5de38c1e5592a7f5060054ea2c4 to include the sync changes. Formatting, unused dependency patches, both GraphQL checks, all 36 package typechecks, and the files/dependencies knip pass succeeded. The overall check failed.
• Lint found eight errors: missing effect reasons in AssistantSelectionToolbar.tsx (4), ScheduledTasksSettings.tsx, and ThreadTerminalDrawer.tsx; input wrapped in act in ComposerPromptEditorTiptap.citationDraft.browser.test.tsx; unused useCallback in mobile useOpenPullRequest.ts.
• Export knip found 10 unused exports across timeline/sidebar helpers, sidebarProjectGrouping, threadShell, threadSnapshotHttp, and preview-count constants in contracts settings.
• The changed-test run (663 selected files) aborted during browser collection after cold Vite optimization reloaded test frames, then Playwright threw route.fulfill: The object has been collected to prevent unbounded heap growth. This is not a passing test run.
• A serial focused run of 12 browser files completed: 103 passed, 4 failed. A warm rerun confirmed the same failures without the optimization/reload error. Two nested-diff keyboard tests in MessagesTimeline.browser.test.tsx use updatedAt: {} and throw RangeError: Invalid time value in DateTime.formatIso through turnItemDetailRevision. Two SettingsPanels.restore assertions expect outdated usage-limit labels; the UI has “Resume after usage limits” and “Snooze until limits reset”.
• Full Claude adapter file: 277 passed. Full Codex adapter file: 113 passed, 1 timeout, in “stops a running guarded turn when Codex reports the allowance used up”. The same test also timed out within its describe block and when run alone (120-second project timeout). The suspected notification/start-registration race is a diagnosis candidate, not yet a proven root cause.
• Real Electron client: used a read-only snapshot copied into this worktree's isolated .t3. Initial module loading failed with ERR_INSUFFICIENT_RESOURCES; Reload recovered. Verified General/Threads settings navigation, Escape dismissal, attachment menu integration entries, and quick-message state IPC. This was a limited runtime pass, not full fork-flow coverage. No paid agent turn was sent; Replay scenarios were unavailable in this runtime.
• Real web client verification is blocked: T3 Browser panel reports available:false. Real mobile verification is blocked: Agent device access is disabled in this environment and requires enabling Settings → Integrations → Devices for a new agent session.

No source changes, branch pushes, merges, or releases were made during this follow-up. Test failures remain outstanding. Desktop test windows were hidden and the captured development process tree was stopped.
