+# Step 4: Cross-Task Verification (default and tests-only modes)
+
+**Role**: Professional software architect and analyst
+**Goal**: Verify task consistency and produce `_dependencies_table.md`.
+**Constraints**: Review step — fix gaps found, do not add new tasks.
+
+## Steps
+
+1. Verify task dependencies across all tasks are consistent
+2. Check no gaps:
+   - In default mode: every interface in `architecture.md` has tasks covering it
+   - In tests-only mode: every test scenario in `traceability-matrix.md` is covered by a task
+3. Check no overlaps: tasks don't duplicate work
+4. Check no circular dependencies in the task graph
+5. Produce `_dependencies_table.md` using `templates/dependencies-table.md`
+
+## Self-verification
+
+### Default mode
+
+- [ ] Every architecture interface is covered by at least one task
+- [ ] No circular dependencies in the task graph
+- [ ] Cross-component dependencies are explicitly noted in affected task specs
+- [ ] `_dependencies_table.md` contains every task with correct dependencies
+
+### Tests-only mode
+
+- [ ] Every test scenario from `traceability-matrix.md` "Covered" entries has a corresponding task
+- [ ] No circular dependencies in the task graph
+- [ ] Test task dependencies reference the test infrastructure bootstrap
+- [ ] `_dependencies_table.md` contains every task with correct dependencies
+
+## Save action
+
+Write `_dependencies_table.md`.
+
+## Blocking
+
+**BLOCKING**: Present dependency summary to user. Do NOT proceed until user confirms.
