| Substitute the right number into the wrong command | A count of relative motor increments is treated as an absolute wheel-position target. | Recover the interface’s counted participant, unit and initial-state use; construct the input it actually accepts. |
| Check only the middle calculation | The robot arithmetic is correct while rolling or successful completion remains unsupported for an actual-travel claim. | Add the physical and observation contributions consumed by that stronger claim, or return the conditional design. |
| Treat a sufficient abstraction as complete physical design | A gear colouring is taken to establish torque or mechanical compatibility. | State the bounded direction consequence and obtain the missing mechanical account when the decision requires it. |
| Repair the drawing while leaving the arrangement unchanged | An odd-cycle edge is deleted from the contact graph but the gears remain meshed. | Change the actual contact or revise the contact rule with its physical basis, then reconstruct the graph consequence. |
| Count reservations as occupants | Three cards outside the free pool are reported as three visitors inside during handover. | Retain Reserved and Awaiting-return states, or report the resulting occupancy bound. |
| Preserve local rules while duplicating a shared resource | Each entrance has its own three-card stock and both are used for one room. | Use one total stock or a partition of it; transfer existing free cards when balancing entrances. |
| Traverse every contribution before using a sufficient result | A proof already excludes a design, yet simulation and implementation continue as compulsory stages. | Return the proved physical obstruction under its assumptions and choose a revised design question. |
| Ask a contributor for an unexplained answer | The receiver gets a count, proof or program whose needed meaning cannot be recovered. | Request the particular interpretation, decisive argument or operating condition required by the next use. |
