observePullRequest used to reveal and focus the explorer pane, and the persisted focus leak then made ambient tab opens (sidebar agent clicks, reconcile auto-open) insert agent tabs into the explorer pane while the main pane sat empty.
PR detection now only background-adds the PR tab to the explorer pane, with no reveal and no focus change, so a tab the user already opened elsewhere stays where it is.
Placement policy is centralized in workspace-layout-actions.ts (resolvePlacementPane / insertNewTabIntoPane): explicit paneId wins, and ambient entity opens (agent, provider_subagent, terminal, draft, browser) reroute from the explorer pane to the primary pane. explorerPaneId is a required input so callers cannot silently fail open.
Pane-rail + affordances thread explicit paneId instead of focus-then-open.
* fix(ci): skip unrelated required checks cleanly
Matrix jobs had to start no-op runners to preserve interpolated required-check names. Static named jobs let GitHub report genuine skipped conclusions while keeping those names stable.
* fix(ci): gate changes to install patching script
* fix(ci): route cross-package test contracts narrowly
* fix(ci): keep routed contracts merge-blocking
* fix(server): exclude nested test utilities from builds
* fix(ci): cover app-owned native and browser domains
* refactor(ci): align tests with runtime domains
Own browser specs, desktop specs, and Electron-only app code by stable directories so PR routing does not depend on filename conventions. Keep desktop integration coverage inside the required desktop check.
* fix(ci): keep routing and desktop suites isolated
The routing regression must run before dependency installation, and desktop Vitest must not collect Playwright-owned specs.
* fix(ci): isolate desktop e2e runtime
* perf(test): isolate Playwright workers
* perf(test): parallelize Playwright within specs
* fix(test): keep Playwright file scheduling
* fix(test): share dynamic Metro fixture
* fix(test): preserve own-host restart fixtures
* fix(ci): preserve routed contracts after rebase
* Stabilize Playwright wheel-scroll assertions
