Summary

lib/checkout_sdk/api_client.rb requires csv when the SDK loads (it parses text/csv responses). From Ruby 3.4, csv is no longer a default gem, so without declaring it the SDK fails to load with a LoadError for csv. This declares it as a runtime dependency.

Changes

• checkout_sdk.gemspec: spec.add_dependency 'csv', '>= 3.0'.

Testing

Unit specs on Ruby 2.7 and 3.3 give the same results as master, and the SDK loads with csv 3.3.6.

Breaking changes

None. On Ruby 3.3 and earlier csv was already available as a default gem.

🔬 Debug — why this classification?

Each reason code emitted by the classifier, its source clause in the AI in SDLC Control Framework, and what it means.

Reason code	Kind	Clause	Meaning
no_low_class_matched	informational	§2.2 (fall-through)	None of the deterministic Low classes (§2.2.3, §2.2.4, §2.2.7, docs-only) applied; classifier fell through to LLM evaluation.
prod_source_modified	informational	§2.1 M7 (informational)	At least one file is non-doc, non-test, non-IaC — i.e. application source code was modified.
2.2.6_logical_extension — The change only adds a runtime dependency declaration for an already-used stdlib gem (csv) in the gemspec, introducing no new code paths, auth changes, persisted data, or external integrations.	classifying	§2.2.6	Sonnet 4.6 evaluator promoted minor → low: the change reuses existing code paths and does not cross a trust boundary.

Kinds:

• classifying — this rule contributed to the chosen tier.
• informational — context only; did not by itself decide the tier.

See issue #3 for the proposal to formalise this map as Appendix A of the standards doc.
