QueryGroupedChannelsResponseAdapterTest to cover deliveryEvents, name,
sharedLocations, skipLastMsgUpdateForSystemMsgs, userMessageReminders, quotes,
reminders, and countMessages, using each fixture’s expected value so adapter
mappings for all added properties are validated.

Did the uitests fixtures get missed? http_channel.json and http_channels.json are short a few of the now-required keys, so the mock responses won't parse. Snapshot tests are dispatch-only, so CI wouldn't have caught it.

Good catch, fixed it. Another reason to finish converting these ui tests to the e2e ones running in PRs

Swapping the invented values for real ones is right, but it leaves the Unknown(value) path with no coverage anywhere in the repo. That is the guarantee you describe in the body: the old field was a raw String that took anything, the new one is a sealed enum, and Unknown(s).value == s is what stops a new server-side automod mode from changing behaviour. One fixture with an unrecognised value would lock it in.

You are right, and it is worse than no coverage: the invented none/empty values were unrecognised, so the old fixture was exercising the Unknown path by accident, and swapping them for real values took that away.
Added ChannelConfigEnumParsingTest, which parses the shared fixture with future_mode, future_behavior and future_blocklist and asserts two things: the models resolve them to Unknown(value), and the value still reaches the domain as the raw wire string. Deriving the JSON from ChannelDtoTestData.configJson keeps the required fields in one place, and it self-checks, since a replacement that stopped matching would leave a real value and fail the Unknown assertion.
That covers automod, automod_behavior and blocklist_behavior. push_level has the same sealed shape but is nullable and absent from the fixture, so I left it out rather than invent a payload for it.

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.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.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.Summary by CodeRabbit
