Task 04: E2E and full verification

Acceptance

• Desktop Playwright spec covers: subtask dragged onto another root's nest zone re-parents (assert API parent_id and sidebar nesting, no reload); inherit_parent subtask ends with shared_group (assert via API metadata); root dragged onto root nests; a task with children offers no nest zone; a drop on an invalid row is a no-op; sibling reorder still works.
• Mobile-chrome touch variant covers the same re-parent flow via Input.dispatchTouchEvent.
• make fmt then make typecheck test lint pass from the repository root.

Verification

cd apps/web && pnpm e2e:run e2e/tests/task/subtask-reparent-drag-drop.spec.ts
cd /home/clem/.kandev/tasks/re-parenting-from-dr_0b8/kdlbs-kandev && make fmt && make typecheck && make test && make lint

Note: run pnpm install --frozen-lockfile from apps/ once if this is a fresh worktree (missing node_modules breaks pnpm commands and the commit hook).

Files likely touched

• apps/web/e2e/tests/task/subtask-reparent-drag-drop.spec.ts (new) — model structure, seeding, and sidebar interaction on apps/web/e2e/tests/task/subtask-detachment.spec.ts; drag mechanics via locator.hover() + page.mouse.down() + stepped mouse.move() + mouse.up() (dnd-kit needs >8px movement before activation).
• Mobile variant: same spec gated to mobile-chrome project or a sibling spec, using the Input.dispatchTouchEvent pattern from apps/web/e2e/tests/mobile-automations-scroll.spec.ts.

Dependencies

Tasks 01–03.

Inputs

• Spec Scenarios (each maps to a test), plan E2E section, existing subtask-detachment e2e specs and helpers (apps/web/e2e/helpers/api-client.ts createTask/updateTask with parent_id and workspace_mode).

Output contract

Report the spec files, exact commands and results (including per-scenario pass counts), files changed, blockers, residual risks; update this task and plan.md when acceptance passes.

Results

• Desktop: pnpm e2e:run tests/task/subtask-reparent-drag-drop.spec.ts --shards 1 — 5 passed (subtask→root reparent + workspace-mode normalization, root→root nest, no nest zones for a task with children, subtask-row drop no-op, sibling reorder regression).
• Mobile: pnpm e2e:run --project mobile-chrome tests/task/mobile-subtask-reparent-drag-drop.spec.ts --shards 1 — 1 passed (touch drag via CDP Input.dispatchTouchEvent; source handle and target zone are scrolled into view first — the sheet scrolls and off-viewport coordinates make raw mouse/touch events no-ops).
• Root verification: make fmt, make typecheck, make lint pass (umask 022). make test: all changed packages pass; residual failures are pre-existing environment issues (launchd/systemd/cli-shim backend tests, Docker-bridge-dependent http-git-server.test.ts, load-sensitive file-browser timeouts that pass in isolation) — verified failing on the stash-clean base.
• Files changed: e2e/tests/task/subtask-reparent-drag-drop.spec.ts (new), e2e/tests/task/mobile-subtask-reparent-drag-drop.spec.ts (new). Temporary diagnostic spec mobile-drag-diag.spec.ts created and removed.
