Goal

PawWork should keep the immediate fixes from #412, then harden the two boundaries that made the May 4 packaged-app failure dangerous:

• Temporary resize/drag/overlay states must not be able to leave the whole UI unclickable.
• Explicit session routes such as /:dir/session/:id must not be overwritten by project-opening or layout sync logic.

When this is done, the app should have a clear ownership rule for these interactions, plus regression coverage that exercises the delayed failure modes.

Scope

In scope:

• Audit all app-level interaction locks that can affect pointer events, especially resize, drag, overlays, dialogs, dropdowns, and side panels.
• Define the smallest shared release contract for temporary interaction locks: all release events, route/visibility/blur cleanup, and whether a timeout fallback is needed.
• Replace ad hoc long-lived global pointer-events disabling where it can deadlock the UI.
• Separate project-opening navigation from explicit session navigation. Suggested actions: openProject(projectRoot), openSession(directory, id), and newSession(directory).
• Ensure layout effects respond to the current URL instead of re-navigating over an explicit /:dir/session/:id route.
• Add delayed-stability e2e coverage for explicit session switching and post-resize clickability.

Out of scope:

• Redesigning side panels, tabs, or the session UI.
• Rewriting the router or changing route shapes.
• Changing the product decision from fix(app): open projects to new session #407 that opening a project defaults to a new session route.
• Packaging native watcher dependencies, which is covered by fix: package native watcher in desktop builds #412.

Relevant files or context

Context:

• fix: package native watcher in desktop builds #412 is the urgent release fix for native watcher packaging, a resize cleanup fallback, and session route regression coverage.
• The follow-up here is to make the underlying interaction and route ownership boundaries less fragile, not to expand fix: package native watcher in desktop builds #412 further.

Likely files:

• packages/app/src/pages/layout.tsx
• packages/app/src/pages/layout/sidebar-items.tsx
• packages/app/src/pages/layout/pawwork-sidebar.tsx
• packages/app/src/pages/session/helpers.ts
• packages/app/src/pages/session/session-side-panel.tsx
• packages/ui/src/components/resize-handle.tsx
• packages/app/e2e/sidebar/sidebar-session-links.spec.ts
• packages/app/e2e/commands/panels.spec.ts

Verification

• Add or update unit tests for any extracted route/navigation helper semantics.
• Add e2e coverage where clicking an existing session remains on /:dir/session/:id after a delayed stability window, not just immediately after the click.
• Add e2e coverage where project opening still lands on /:root/session.
• Add e2e coverage where a resize/drag gesture releases correctly and sidebar actions remain clickable afterward. At minimum, verify new session, an existing session row, and one non-session control.
• Run the targeted app unit tests and affected Playwright specs.
• Confirm there are no unrelated UI copy, layout, or route-shape changes.
