QueryGroupedChannelsResponseAdapterTest to cover deliveryEvents, name,

Looks good. One thing at the PR level: the model now parses quotes, reminders and count_messages, but Config has nowhere to put them, so they are read and then dropped. Is that tracked somewhere, or left for later on purpose? Rest is inline, all small.

On the PR-level point: it was not tracked, it is now, as AND-1498. It is a bit wider than those three, the model parses eleven fields |

Goal
Parse the channel config with the generated
ChannelConfigWithInfoand delete the hand-writtenConfigDto.Part of AND-1291
Implementation
DownstreamChannelDto.configatChannelConfigWithInfoand dropConfigDtowith its mapper. The generated model, its four enum adapters andChannelConfigWithInfo.toDomain()were already in place for the generatedChannelResponse, so this slice adds no model or mapper.configJsonand oneexpectedConfigserving both paths, with the real enum values (disabled,flag,block) in place of the inventednoneandempty.ChannelConfigWithInfo is correctly mapped to Configto compare the wholeConfig, against a fixture where every value differs from the domain default it maps onto. It previously asserted five scalars against an all-true fixture. Differing from the default is what matters: a dropped field falls back to itsConfigdefault, so a fixture value that happens to equal that default hides the drop, and most of these default totrue.EventChatJsonProviderandQueryGroupedChannelsResponseAdapterTest.DownstreamChannelDto.confignullable, mapping an absent config toConfig()as the generatedChannelResponsepath already does. The backend leavesconfignil for a channel whose type is no longer in the app config, and the field has noomitempty, so it arrives as"config": null. A non-null field there loses the entire response rather than degrading that one channel.Notes
The generated model marks 10 fields required that the hand-written DTO accepted as absent, including
created_at,updated_at,name, andquotes,remindersandcount_messages, whichConfigDtodid not declare at all. Every one is a plain non-omitemptytag on the backend's channel config struct, so the current wire always sends them. That includesdelivery_events, despite the DTO carrying a= truedefault for it.The four enums resolve unknown values to
Unknown(value)and the mapper passes.valueto the domain, so an unrecognised mode maps to the same string the previousStringfield produced.The generated model also parses eleven fields the domain
Confighas nowhere to hold, so they are read and dropped:quotes,reminders,count_messages,blocklist,blocklists,automod_thresholds,allowed_flag_reasons,chat_preferences,grants,partition_sizeandpartition_ttl.ConfigDtodid not declare any of them either, so nothing regressed, but the gap is now visible and tracked in AND-1498.Testing
queryChannels(three channels) and the single-channelwatch: every newly required field present,automod=AIcarried through the enum, nested commands mapped, and the two endpoints produced an equalConfig.typingEventsEnabled,deliveryEventsEnabled,searchEnabled,isThreadEnabled,muteEnabled,urlEnrichmentEnabled,pushNotificationsEnabled,skipLastMsgUpdateForSystemMsgs,automod,sharedLocationsEnabled).ChannelConfigEnumParsingTestpins the forward-compatibility claim above: unrecognised modes resolve toUnknown(value)and reach the domain as the raw wire string.DownstreamChannelDtoAdapterTestcovers a channel arriving withconfig: null, which parses and maps toConfig().Summary by CodeRabbit
