C.29.3:8 - Common Anti-Patterns and How to Avoid Them

Misuse	Why it fails here	Repair
Send an unrepresentable answer	A signed field wraps or rejects a value that is valid in the calculation.	Change the encoding or realization, or restrict the admitted input.
Split a command without recovering composition	Two absolute targets do not add like relative increments.	Explain the state and rule connecting the completed commands.
Read the carrier by its familiar scale	The circuit’s physical average uses a different decoding from its inputs.	Derive and use the receiving scale.
Infer exact occupancy from unavailable cards	Some assigned cards are outside during reservation or return.	Use the four-state account or retain the upper bound.
Treat one successful run as every required run	An untested endpoint or interleaving can change the result.	Supply the argument or evidence that covers the declared use.
Require a new trial for an adequate conditional design	The trial may leave the design decision unchanged.	Finish with the sufficient conditional consequence; obtain further information when its use warrants it.
