+steps:
+  - id: link-target
+    task: task01_link_address
+    action: debug
+    profile: hazard3-sim
+    target: hazard3-baremetal
+    command: stemctl debug hazard3-sim rv32i-asm L08 1
+    board:
+      show: [pc, rs1, immediate, jalr, target, link, waveform]
+      highlight: [pc_plus_4, pc_relative_target, jalr_bit_zero]
+      question: Dlaczego link jest taki sam dla JAL i JALR przy tym samym PC?
+    evidence: [jal_target, jalr_target, link, trace_vcd]
+  - id: abi-map
+    task: task02_abi_registers
+    action: test
+    profile: hazard3-sim
+    target: hazard3-baremetal
+    command: stemctl test hazard3-sim rv32i-asm L08 2
+    board:
+      show: [register_index, abi_class, class_counts]
+      highlight: [arguments, callee_saved, temporaries, fixed]
+      question: Które rejestry funkcja wywołana musi odtworzyć przed return?
+    evidence: [all_32_classified, class_counts]
+  - id: nested-calls
+    task: task03_call_stack
+    action: debug
+    profile: hazard3-sim

+    command: stemctl debug hazard3-sim rv32i-asm L08 3
+    board:
+      show: [call, ret, link, depth, return_address, underflow, waveform]
+      highlight: [push_104, push_204, pop_204, pop_104]
+      question: Dlaczego pierwszy return używa adresu 0x204, a nie 0x104?
+    evidence: [nested_depth, return_order, underflow, trace_vcd]
