NSTD.1:5.4 - Role-specific first moves

Worker	First source-selection move	Common hidden overread	Repair when that difficulty occurs
Teacher	Name the source spine and reconstruction task.	Learner interest means learning occurred.	Add source-return question and later `NSTD.6` row.
Architect	Name selected structures, candidates, residuals, and actual-structure feedback.	Explanatory story is the architecture decision.	Route decision authority to architecture decision owners.
Scientist	Name mechanism, calculation, uncertainty, and proof or evidence boundary.	Story coherence is evidence closure.	Add evidence owner and source-return condition.
Story designer	Name source pack, continuity, agency, and non-use boundary.	Dramatic surprise authorizes source violation.	Reopen source-pack selection before ordering.
Live commentator	Name event stream, provisional interpretation, and later official return.	Live causal claim is settled fact.	Mark uncertainty and telemetry return.
AI-agent operator	Name material, required relations and the proposed use.	Fluent prose silently adds a cause or drops a constraint.	Inspect and repair through `NSTD.7` and `NSTD.6`; apply `C.35` only for an architecture use.
