Code Review
This pull request introduces a new residential object (represented by the AnonymizerFeed class) to the anonymizer record in the GeoIP2 Insights model, allowing users to access residential proxy data such as confidence, provider name, and last seen date. The feedback suggests two improvements: using the safe navigation operator (&.) in Anonymizer#initialize for cleaner, more idiomatic Ruby code, and ensuring that nil values are correctly cached in AnonymizerFeed#network_last_seen to prevent redundant lookups when the date is missing.

This adds a new residential sub-object to the anonymizer object in the GeoIP2 Insights web service response. It includes a confidence score, the provider name, and the date the network was last seen for residential proxies. The residential object may be populated even when no other anonymizer attributes are set. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The network_last_seen methods memoized only successfully parsed dates. When the value was unset, the defined? guard never became true, so every call repeated the hash lookup instead of returning the cached nil. Assign the instance variable in the nil branch as well so the lookup runs at most once. This fixes the newly added AnonymizerFeed#network_last_seen along with the pre-existing instances of the same pattern in Anonymizer#network_last_seen and AnonymousPlus#network_last_seen, and updates the lazy-parsing examples in CLAUDE.md to match.

Looks good. Claude had a couple comments but they seem unnecessary to me. I'll leave them in case you want to look at them.

Test gap (major): the absent-residential and absent-anonymizer paths are untested. Insights#initialize always calls Anonymizer.new(record['anonymizer']), and most Insights responses carry no residential data (and non-Insights responses have no anonymizer at all), so Anonymizer.new(nil) / AnonymizerFeed.new(nil) are the common paths. This record.nil? ? nil : record['residential'] guard is the only thing preventing a NoMethodError, yet the sole fixture always fully populates residential.
Suggest adding a test with (a) an anonymizer that has only residential (the documented "may be populated even when no other anonymizer attributes are set" case) and (b) an anonymizer-less response, asserting residential is non-nil and its three fields return nil without raising. GeoIP2-php's InsightsTest.php has this exact case as a model.

Claude, on behalf of Greg: Added coverage in commit f9d3fbc (test/test_record.rb): test_insights_no_anonymizer builds a Model::Insights from a raw hash with no anonymizer key at all and asserts every anonymizer/anonymizer.residential getter returns nil with no NoMethodError, and test_insights_anonymizer_without_residential covers an anonymizer present without a nested residential key, asserting residential.confidence/.network_last_seen/.provider_name are all nil.

Test gap (major): this nil-date branch is untested — network_last_seen is only exercised with a valid date string. A residential feed with confidence/provider but no date is a normal payload; if this if !date_string guard regressed, Date.parse(nil) would raise. Note commit 39e1d6f ("Memoize nil results…") could be fully reverted and the suite would still pass.
Suggest asserting network_last_seen returns nil when absent (for the feed, top-level Anonymizer, and AnonymousPlus), and that a repeated call still returns nil to pin the memoization.

Claude, on behalf of Greg: Added coverage in commit f9d3fbc (test/test_record.rb): test_anonymizer_feed_network_last_seen_absent, test_anonymizer_network_last_seen_absent, and test_anonymous_plus_network_last_seen_absent each assert network_last_seen is nil (no Date.parse(nil) raise) when the date key is absent, covering Record::AnonymizerFeed, Record::Anonymizer, and Model::AnonymousPlus respectively. Verified the gap by temporarily removing the if !date_string guard in AnonymizerFeed#network_last_seen — 3 of the new tests failed with TypeError: no implicit conversion of nil into String, confirming they would catch a regression of this guard.
horgh's review of the anonymizer.residential addition flagged two untested paths: - Insights#initialize unconditionally calls Anonymizer.new(record['anonymizer']), and Anonymizer#initialize unconditionally calls AnonymizerFeed.new(record['residential']). The common case has neither key present, so Anonymizer.new(nil) and AnonymizerFeed.new(nil) are the hot paths, guarded only by `record.nil? ? nil : record['residential']`. Add coverage for a Model::Insights built from a raw hash with no "anonymizer" key at all, and for an "anonymizer" present without a nested "residential" key, asserting every getter returns nil with no NoMethodError. - network_last_seen's `if !date_string` guard, which prevents Date.parse(nil) from raising when the date key is absent, was untested in all three places it is duplicated: AnonymizerFeed, Anonymizer, and Model::AnonymousPlus. Add a test per class asserting network_last_seen is nil when the date key is absent. Verified the AnonymizerFeed test actually catches a regression: with the guard temporarily removed (network_last_seen calling Date.parse(date_string) unconditionally), 3 of the 5 new tests failed with "TypeError: no implicit conversion of nil into String" as expected. Restored the guard afterward. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
