- Around line 170-174: Update the logger migration Definition of Done checklist:
revise the StreamLogger.configure item to reference logConfig.priority instead
of logLevel, remove the checklist item covering the deleted StreamLogHandler
bridge and its tests, and replace any remaining “bridge’s callers” wording with
“logger call sites.”

Fixed on the sort rung, where that paragraph was rewritten: the summary now reads "No upstream stream_core work — and three operators chat should deprecate rather than port". $nor is no longer an upstream ask at all; it is dropped, and a preset carrying it decodes through Filter.raw.

@xsahil03x, verification does not show the stated rewrite in #2956.
core-migration/08-query-dsl.md still says on Line 7:

The original ask is satisfied on this rung — line 7 reads "One small upstream ask ($nor)", which is the exact wording you proposed, and it is consistent with the rest of the file at this point in the stack, where $nor is still listed as upstream work.
My earlier reply overreached by describing the end state. The $nor-is-dropped rewrite belongs to #2957, which is where the Filter and Sort decisions are actually taken; pulling it down here would put a conclusion in a tree that has not reached it yet. On #2957 the same line reads "No upstream stream_core work — and three operators chat should deprecate rather than port".

Ours was a fork with the same `run` signature, the same `Future.sync(work)` and the same `whenComplete(...).ignore()` cleanup, down to the doc prose — and core's test file covers the same six cases, so deleting ours loses no coverage. `client.dart` imports it with a `show` clause rather than core's barrel, which would collide with `User`, `Filter`, `TokenManager` and `SystemEnvironment` in that file. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Both were forks. `SystemEnvironment` was identical — same constructor, same eight fields, same nullability — so it is re-exported from `stream_chat.dart` through a `show` allowlist and existing usage keeps compiling. `SystemEnvironmentManager` shared the class name, the extension name and a byte-identical `xStreamClientHeader` body, and was never exported. Core's manager is the better one: it takes the SDK baseline as a constructor argument and snapshots the SDK-owned fields rather than holding a reference, because `SystemEnvironment` is not final and a subtype could drift the values an update is meant to lock. It also rejects an unrecognized `sdkIdentifier` rather than only comparing precedence. Chat's manager tests are deleted rather than ported: core covers the manager with 13 cases and the header extension with 9, a superset of ours. What this package still owns is the baseline, so one test pins that. `_systemEnvironmentManager` stays static. Making it per-instance also breaks the public `defaultUserAgent` static that reads it, so that moves to the phase retiring `additionalHeaders` alongside it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`UploadState`'s freezed variants were named `Preparing`, `InProgress`, `Success` and `Failed` — four strikingly generic names in the public surface. `Success` was contended three ways: this union, `PagedValue`'s success variant in `stream_chat_flutter_core`, and `Result`'s in `stream_core`. There are already 13 `hide Success` import clauses in this repo working around the first two, and exporting `Result` needs the name free. They become `UploadStatePreparing`, `UploadStateInProgress`, `UploadStateSuccess` and `UploadStateFailed`. Deliberately not `UploadPreparing` / `UploadSuccess` / …, tempting as the symmetry is: those are `stream_core`'s `AttachmentUploadState` variant names, and adopting the upload task API puts that union in scope alongside this one, which stays on `Attachment` for persistence. Matching core's names now would just move the collision. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A failed request now reports one of `stream_core`'s four sealed `StreamException` kinds instead of a `StreamChatNetworkError`, so a Stream error is handled the same way here as in our other SDKs. `typedef StreamChatException = StreamException` gives the family a chat-shaped name, mirroring `StreamFeedsException`; the kinds keep theirs, since those are what a `switch` matches on. `StreamHttpClient._parseError` delegates to core's mapper, so all seven verb wrappers throw a `StreamChatException`. `ApiErrorInterceptor` is installed ahead of the logging interceptor, which is also what the generated client needs: it goes straight to `_dio.fetch` and never reaches those wrappers. `ChatErrorCode` is deleted. The backend registry has no code 23 or 24, so `requestTimeout` (23) never matched a real response — the wire code is 48, which core already has — and `maximumHeaderSizeExceeded` (24) and `undefinedToken` (1000) were never wire codes at all. Retry classification stays ours, since retryability is policy the caller owns, but it now follows core's table: a request that never reached the server, a 5xx, a 429 and a 408 retry; another 4xx, a cancelled request, broken credentials and anything marked unrecoverable do not. Previously only failures without a parseable error body retried, so a 500 or a 429 did not — failed messages will now retry where they used to give up. `PagedValue.error` and every `errorBuilder` carry the new type, so the break lands once rather than leaving the old error as the UI currency. The list controllers' catch-and-rewrap collapses: what they catch is already the right type, and anything else becomes a `StreamClientException` keeping the original as its cause. Two "no internet vs slow connection" switches now key off the failure kind instead of a dio transport enum, which also fixes them covering only three of the timeout types. `StreamChatNetworkError` is deprecated rather than deleted, because endpoints the OpenAPI migration has not moved still flow through the hand-written verb facade. Nothing raises it, so an `on StreamChatNetworkError catch` clause still compiles and quietly stops matching — the migration guide says so in those words, since a deprecation warning does not convey it. `StreamChatError` stays and is not deprecated: it is still the base for the SDK's own precondition throws and for the UI's attachment-validation results. `core-migration/03-errors.md` records what has to happen before the file that declares it can go. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`Token` becomes `UserToken`, `TokenProvider` becomes an interface rather than a `Future<String> Function(String)` typedef, and our `AuthInterceptor` gives way to core's. The client holds a `TokenManager.unconfigured()` and configures it on connect, since core's primary constructor needs a user id that chat does not have until then. `_connectUser` now takes a single `required TokenProvider`, so all four entry points configure the manager the same way. It previously took `Token?` *and* `TokenProvider?` and asserted at runtime that exactly one was set. Core's interceptor fixes three bugs ours had: no guard against a refresh loop, no guard against refreshing across a user switch, and no `FormData` re-clone — so a retried file upload replayed streams the first attempt had consumed. It also skips refreshing a static provider, where a re-fetch returns the same token, and `UserToken` parses `exp`, which is what lets a refresh happen before the server refuses rather than only after. Anonymous connections now identify as `!anon` instead of a client-generated random id. This is forced rather than chosen: `StaticTokenProvider` validates that a token's id matches the id it is registered under, and `UserToken.anonymous()` is always `!anon`. It is also right — the backend defines `AnonUserID = "!anon"` and pins it so a client cannot claim another identity, and its subscription store already counts each `!anon` client separately, so sharing the id is expected. Still worth one live anonymous connect before release; `core-migration/04-token-and-auth.md` says why source alone cannot settle it. `StreamChatClient.devToken` is removed rather than retyped. It minted a `devtoken`-signed JWT, which only an app with development tokens enabled accepts, so shipping a minter in the SDK invites it into production. Tests build their own with `testUserToken`, the way `stream_feeds_test` keeps `generateTestUserToken`. Our token tests are deleted rather than ported: core covers `AuthInterceptor`, `TokenManager`, `UserToken` and `TokenProvider` with 83 cases against our ~30. `TokenManager` joins the barrel allowlist — it appears in the exported signatures of `StreamHttpClient` and `StreamChatApi` but was never nameable.

`package:logging` leaves the repo. The SDK writes through `stream_core`'s
`StreamLogger`, so `logLevel` and `logHandlerFunction` collapse into one
`logConfig`, `client.logger` is a `StreamLogger`, and `detachedLogger`,
`defaultLogHandler` and `LogHandlerFunction` are gone along with the
`package:logging` re-export and dependency.
An earlier attempt bridged instead — a handler forwarding core's records into
chat's `Logger` — and that was the wrong call: it left two logging systems
alive, which is the problem this was meant to solve, and it was code whose only
purpose was to be deleted later. v11 already breaks the error and token layers,
so this costs a consumer one more entry in a guide they are reading anyway.
It also could not wait. An unconfigured `StreamLogger` is silent, so every
record from the HTTP client and the token manager was going nowhere, and
adopting core's WebSocket would have taken chat's connection logging with it.
The default is unchanged: `const StreamLogConfig()` is warnings and errors to
the console, which is what this package already documented.
Tags follow core's shape — a class takes `{String tag = '...'}` and builds its
own logger, rather than being handed one. The per-channel identity that used to
live in a logger's *name* is now in the tag, appended rather than nested
(`SCh:RetryQueue:messaging:general`), so filtering by subsystem still works.
`stream_chat_persistence` moved too; it had its own detached logger, default
handler and emoji map.
Alongside it, three forked interceptors become one. Core owns the user-agent
header and the connection id, and its `LoggingInterceptor` replaces our
344-line copy; what stays is the part core has no concept of, applying
`StreamChatClient.additionalHeaders`. The pipeline reads as a list of
null-aware elements over `let`, so an absent dependency drops its interceptor
rather than guarding it, and `ApiErrorInterceptor` sits ahead of logging so
what gets logged is the mapped failure.
`api_key` stays a query parameter rather than moving to core's header-setting
`ApiKeyInterceptor`: the server appears to accept both, and changing a working
wire contract buys nothing.
Every call site in the 13 hand-written `*_api.dart` files is untouched, which
is what keeps the rest of this migration independent of the OpenAPI one.

Two indexes cutting across the phase files, because decisions were surviving only as sentences buried in them. `DEFERRED.md` lists everything consciously postponed, grouped by what would unblock it: waiting on a `stream_core` release, needing a live check that source cannot settle, or waiting on a later phase. It also carries the shape of the `StreamChatConfig` that absorbs several of the rows, sequenced into the cleanup phase rather than done piecemeal. `UPSTREAM.md` covers the other direction — what chat has that every product needs. The retry table is the clearest case: `ERROR_LAYER.md` specifies it, chat now implements it, and feeds independently re-derived a partial version. It also records that core ships `HeadersInterceptor` and `ConnectionIdInterceptor` with no tests, which is why chat's kept theirs. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The plan called `$ne`, `$nin` and `$nor` a hard upstream block in four places. Checked against the other SDKs, only one of them is. Android deprecates `ne` — "inefficient and causes performance issues, it will not be supported in the future" — and every `nin` overload, and the JS SDK never declared either in its `QueryFilter` type. So `stream_core` is right not to have them, and chat should follow Android and deprecate rather than push them upstream. `$nor` is a different case: declared in JS beside `$and` and `$or`, present and undeprecated in Swift and Android. It is a logical operator, so it belongs next to core's `AndOperator` and `OrOperator`, and it is the only real ask. Records the evidence so nobody re-derives it, and notes that Swift still exposes the deprecated pair — which reads as an oversight there rather than a signal.

`generated_plugins.cmake` is written by `flutter pub get`, and both the linux and windows copies were committed without `jni` in `FLUTTER_FFI_PLUGIN_LIST`. CI regenerates them during bootstrap, so the working tree came out dirty and the formatting check — which fails on any modified tracked file — went red. Restores what v11 has. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The silence predicate was retyped from `StreamChatNetworkError` to `StreamChatException`, which is the sealed root — so it also suppressed `StreamClientException`, the kind that means the SDK itself failed. A genuine bug during send stopped reaching `FlutterError.reportError`. Narrows it to the two kinds the comment was describing: a refusal the server sent, and a connection that failed. Both leave the message in a failed state for the retry queue, so both are expected in release. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The guide's two `catch` examples both read only `.message`, which lives on the sealed root. A real v10 clause reads `.code` or `.statusCode`, and the Symbol Map maps those onto `StreamApiException` — a subtype. Nothing showed the bridge, so the obvious edit is `on StreamChatNetworkError catch` → `on StreamApiException catch`, which compiles and silently stops handling timeouts, cancellation, auth failures and undecodable responses. That is the same silent break the guide's own warning box claims deleting the old types prevents, so it needed saying. Adds a worked before/after, and notes why the sealed root needs no default arm while `Result.fold` does — `Failure.error` is typed `Object`. Both compile-checked, and the exhaustiveness claim verified by removing a case and watching the analyzer reject it. Also gives `TokenProvider.dynamic` its loader signature, and records that `UserToken` throws on a malformed JWT and on a user-id mismatch. Neither is a compile error; both present as "cannot log in".

The API-error tests asserted inside a `catch` block, so a request that returned instead of throwing passed without checking anything. The reaction controller's generic-exception test checked the message but not the type. Also documents `ChannelDeliveryReporter`'s `tag` parameter, which replaced the `logger` the constructor doc still described. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

`_parseError` reports a `StreamException` now, so five `is StreamChatNetworkError` guards stopped matching and their branches became unreachable. `sendMessage`, `updateMessage`, `partialUpdateMessage` and `_deleteMessage` no longer queued a failed write, so a transient failure waited for the next connection-recovered sweep instead of retrying with backoff. `sync` no longer flushed persistence on the 400 the server answers for a stale `lastSyncAt` or an oversized state, leaving that `lastSyncAt` in place for every later sync to fail on. The sync branch had a test, but it threw a hand-built `StreamChatNetworkError.raw` no pipeline can produce any more, so it stayed green over dead code. It now throws what a rejected request reports.

`X-Stream-Client` moved from chat's own interceptor to `stream_core`'s `HeadersInterceptor` in this branch, and it was the one interceptor whose installation nothing asserted. A miswired `systemEnvironmentManager` would drop the header silently and cost SDK attribution. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`_logger` had landed between a setter and a getter in `WebSocket`, and between two methods in `ChannelDeliveryReporter`. `ErrorResponse`'s dartdoc also still pointed at `StreamChatNetworkError`, which nothing raises any more. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The default channel error state is `stream_chat_flutter`'s, so its entry moves out of `stream_chat_flutter_core`'s changelog. `🚀 Changed` was an invented heading sitting beside `🔄 Changed` in the same release; both fold into one. Two phase-doc claims were wrong: `AppSettingsManager` was not detached and did reach `Logger.root`, and the controllers' error wrap was rewritten rather than deleted — it keeps the original as `cause`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The WebSocket connect URI carries the token twice — as `authorization`, and as `user_token` inside the `json` payload — and both `[connect]` and `[reconnect]` logged it whole at `info`. Raising the priority to `info` is what the SDK documents for development, so anyone debugging a connection wrote a usable token to the console and to whatever handler the app had installed, which for an app forwarding records to a crash reporter means off the device. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…low it 101 of the 127 log sites in these two packages were `info`, including a health check every 20 seconds, a reconnect check every 10, a line per WebSocket frame, one per keystroke, and — in persistence — the name of every call it makes. `info` now carries only what a developer wants to see once: the client created and disposed, the user set and disconnected, the connection opening, established and closing. Per-operation records are `debug` and per-event ones are `verbose`, so raising the priority to chase a problem no longer buries it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
A throwable the SDK does not recognise was wrapped as `StreamClientException(message: error.toString())`, which put the stringified error where a message belongs and left the same text in `cause` a second time. The message now names the load — `Failed to load more channels` — and the throwable survives untouched as `cause`, which is the field that exists to hold it. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`StreamPhotoGalleryController` is the tenth `PagedValueNotifier` and the one outside `stream_chat_flutter_core`, so it was missed when the other nine stopped stringifying the throwable into the message. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Eight tests claimed to add a message to the retry queue; none looked at the queue, and four of them threw a 403, which is not retriable at all. They assert the message reaches a failed state, and the four that use a 408 or a 500 also assert the verdict — so that is what they now say. `StreamChatException` aliasing `StreamException` was pinned by `hasLength(4)` on a four-element literal, which holds whatever the alias does. It now compares the two types. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`08-query-dsl.md` was rewritten here, but its subject is Sort and Filter, which land two and three rungs up — and both rewrite the file wholesale, so nothing this rung wrote survives to the tip. It goes back to what the plan said; #2958 records the same decision with a better citation. The status table said 03, 04 and 08 were unfinished, while the section below it says the column describes the finished stack rather than the PR you are reading it in. The table now says what the tip says. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The collision list still named seven types this branch deletes — `TokenManager`, `AuthType`, `AuthInterceptor`, `ConnectionIdInterceptor`, `LoggingInterceptor`, `InterceptStep` and `LogPrint`. Chat declares none of them any more, so a wholesale export no longer collides on any of them, and the paragraph below that says the list shortens each phase should have said so. Two lines pointed past this rung: the hard-block sentence carried phase 08's narrowed conclusion while the phase doc no longer does, and the parked note promised findings that `07-websocket.md` does not hold yet. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The paragraph still showed `StreamClientException(message: error.toString())`, which is what it was until the message started naming the load instead. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Should we maybe still pass the StreamLogger here instead of the tag - mostly for testing purposes, if we want to stub out the logger? (the same question goes for all the other places where we are passing tag)
Edit: I see that we can easily manipulate the loggers in tests, so this probably doesn't make too much sense. Still, it might be a better approach to inject the logger dependency, instead of constructing it internally.

Question: Do we need to publicly re-export all of these classes? For example, LoggingInterceptor, InterceptStep LogPrint look like SDK internals, I don't think we should expose them transitively. (please correct me if I am missing something)

One small thing: As the changelog would be customer-facing, referencing stream_core here might be a bit confusing - as is general, consumers might not even be aware of the stream_core package.

Replace six hand-written subsystems with
stream_core's, deleting ~3.5k lines of chat code for ~2.4k of adoption. Each was a near-verbatim fork, and three of them had drifted into bugs core has already fixed.🛠 Implementation details
