   Completed: 2026-10-31T22:10:03.171Z

   Completed the local merge in commit 3db991c2d6cc8671fc762dca5620812d4d47e5ce on issue-265-upstream-sync-2026-10-31-401-upstream.

   The commit has the requested base and pinned upstream commit as its two parents. Resolved 61 conflicted files / 99 blocks. The working tree is clean. No push, PR, or modification of main.

   Verification completed:

   • 27 affected packages type-checked individually, including desktop.
   • 512 non-browser test files ran; every initial failure passed in focused reruns.
   • 83 browser files / 475 tests passed in the final single run, after type checks and non-browser checks passed.
   • Every adjacent *.fork.test.ts beside the conflicted files was included.
   • Fixture-database migration tests, MCP core tests, and the context-budget test passed. The measured budget is 5938 / 7668 / 72558 bytes.
   • The commit hook passed formatting and lint. Its sole failure was the known Commit hook fails on every TypeScript change: 74 unused exports on main #256 baseline of 74 unused exports, so I used the authorized --no-verify exception.

   The exact lost-code audit ran against committed HEAD: 24 flagged hunks across 209 jointly changed files — 18 retained with changed structure, six replaced by upstream, zero unresolved drops, zero deleted fork files, and zero unimported fork files. Every judgment and each initially failing test’s cause is recorded in the implementation report. The raw final audit is retained alongside it.

   Restorations and merge fixes:

   • Restored lineage detail rows and model, effort, and workspace metadata.
   • Restored previous-agent clearing and automatic clearing.
   • Restored per-row and expand/collapse-all controls.
   • Restored draggable thread references and missing-shell detail guards.
   • Restored background command and monitor rows.
   • Restored repository identity on the relocated thread details panel.
   • Restored prompt-injected effort filtering.
   • Restored signed-file-URL refresh on workspace and reveal changes.
   • Restored project identity for fork appearance overrides.
   • Restored environment-only project lending when opening pull requests.
   • Retained notification observations across reconnects.
   • Prevented process-parent scans when listener discovery is disabled.
   • Restored owner-visible routed child questions while excluding side chats.
   • Restored upstream’s final recovery-settings check before worktree cleanup.
   • Restored upstream navigation for idle children omitted from the shell.

   Fork code dropped or replaced has these upstream owners:

   Removed fork behavior	Upstream replacement
   Generic listener probing and unidentified-listener handling — three audit flags	PortScanner.probeWebServers: probe configured URLs and list owned listeners.
   Duplicate .git and special-file filtering	WorkspaceEntries: entry-kind filtering and symlink resolution.
   Fork remote-relationship headings and provider lookup	RemoteSubagentRow and DelegatedFromRow.
   Duplicate provider-stack markup	SidebarThreadRow.titleLineIcons.
   Three-tab eviction and its two tests	ServerBrowser capacity reservations: eight tabs per agent and 32 per server. The fork setting now controls stalled-tab recovery.
   Missing-shell navigation restrictions	Upstream openThread and workflow member navigation.
   Automatic favicon subscription wiring	AutomaticProjectFavicon; fork custom icons remain.

   Remaining limits: one Windows-only uninstall test was skipped on Linux. Integrated real-client UI verification, desktop packaging, and paid model evals remain unverified; mobile was out of scope. git diff --check reports nine blank-context whitespace notices inside two patch files that match upstream exactly; it passes with those patch files excluded. No live userdata was accessed or copied, and no dev server or seeding command ran.
