NSTD.7:5.2 - Probe suite for generated narrative

Probe	Question	Pass condition	Failure repair
Source perturbation	If one source relation changes, does the generated narrative change at the right place?	The affected sentence, order marker, or source-return link changes.	Recover source plan; do not rely on prompt fluency.
Structure recovery	Can a reader reconstruct selected source structure from the output?	Reader recovers nodes and relations needed for declared use and knows lost relations.	Add source-return markers or narrow declared use.
Responsibility	Who decides the consequential use and can correct it?	The applicable assignment or decision authority is recoverable.	Resolve that authority question; apply evidence or assurance checks only when those claims are made.
Schema use	Does the result satisfy the constraints that matter to its use?	Required fields and their semantic constraints are satisfied.	Repair the generator or result; use executable validation when it can test those constraints.
Improvement evidence	Is the new variant better under the relevant `NSTD.6` characteristics?	Re-evaluation supports the claimed change without losing protected results. A sufficient one-off comparison can finish here.	Keep an unsupported variant as a candidate. Use `E.22` if the question needs framing, or `E.23` for repeated improvement.
