Use a portable protocol source path.
~/GolandProjects/protocol is specific to one workstation. Replace it with a repository-relative setup step, a clone command, or a configurable path. This lets other maintainers regenerate the field table.

Fixed on this rung. The instruction no longer hard-codes one workstation's path — it names the GetStream/protocol checkout and takes its location from $PROTOCOL_DIR, with the old path as the default.

Use safeCast<bool>() for replacement extraData.
ChannelModel.copyWith accepts Map<String, Object?>?, but its muted and blocked fallbacks use direct as bool? casts. A non-boolean value such as copyWith(extraData: {'muted': 'true'}) can therefore throw instead of matching the safe getter behavior.
Proposed fix
- muted: muted ?? extraData?['muted'] as bool? ?? this.muted,
- blocked: blocked ?? extraData?['blocked'] as bool? ?? this.blocked,
+ muted: muted ?? extraData?['muted'].safeCast<bool>() ?? this.muted,

Fixed in 05cd2e0, extended to disabled and hidden, which had the same cast. A test pins it: copyWith(extraData: {'muted': 'yes', 'blocked': 1}) now falls back to the current value instead of throwing, matching what the getters already did.

Use ChannelFilter in these documentation links.
predefined_filter.dart imports channel_state.dart, which exposes ChannelFilter; it does not import Filter from stream_core. The current links may remain unresolved in generated API documentation.

Fixed in 05cd2e0. predefined_filter.dart imports channel_state.dart and not stream_core, so Filter is not in scope and those three links resolved to nothing. They now name ChannelFilter, which is the typedef the file actually uses.

Phase 08b needs `Filter.raw`, which is unreleased. Melos' `dependencyOverridePaths` points resolution at ../stream-core-flutter while both repos change together, leaving the declared `^0.5.0` constraint honest — reverting is deleting three lines rather than editing a version back. A direct path dependency does not work here: hosted stream_core_flutter 0.5.1 depends on hosted stream_core, so pub cannot reconcile the two. Both packages are overridden, named explicitly because globbing `packages/**` picks up the plugin symlinks under stream_thumbnail/example. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Chat's own `Filter` addressed fields by string, so nothing tied a key to the model it filtered or to the operators the API accepts there. It is replaced by `stream_core`'s sealed `Filter<T>`, with one alias and one field registry per query — the shape `Sort` already took. Each registry is pinned to `x-stream-filter-fields` in the protocol repo by a test that requires every published field to be either declared or listed as omitted with a reason, so a gap has to be written down rather than gone unnoticed. `$ne`, `$nin` and `$nor` are gone: they are deprecated server-side and being withdrawn. `Filter.empty()` is gone too — every filter argument is nullable, which `queryThreads` distinguishes from an empty one. The persistence layer follows: its resolved-filter column is nullable, so a predefined-filter query with no filter stores none. Message flags are the one endpoint left unmodelled; chat has no API for them. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Every alias now points at its field registry and carries a worked example, so the fields a query accepts are reachable from the type a caller already has. Filtering lost its only example when chat's own `Filter` was deleted; this restores one per query rather than the single channel example it had. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
It read as a check against the API spec, but the spec was not consulted: the published set was transcribed into the test by hand. A field added upstream left it green, which is the one case its name promised to catch, and it cost a second list to keep in step with every registry. The reasoning it carried — why a field is declared or left out — moves to the phase doc, which was still claiming `hidden`, `muted`, `blocked`, `members` and `member.user.name` cannot have getters. All five are declared. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Replaces the sibling-checkout `dependencyOverridePaths` block, which only ever worked on a machine with stream-core-flutter checked out next door. On CI the glob matched nothing, melos resolved the published 0.5.0 instead, and every package using an unreleased core API failed to analyze. Pinned to a SHA rather than a branch on purpose. `stream_core_flutter` reaches `stream_core` through the same clone, and pub compares git descriptors rather than resolved commits — a branch ref on one side and a resolved SHA on the other count as two sources of one package, which fails to solve. Both entries name the same commit so the descriptors match. `invalid_dependency` is silenced because a git dependency makes these packages temporarily unpublishable, which is true and intended. It goes when the git dependency does; publishability is still enforced by `lint:pub` and `pana` on master-targeted PRs. Restore hosted constraints before releasing v11, and delete the `chat-integration/v11` branch in stream-core-flutter — its path dependency cannot be published.

`channel_queries_metadata`'s `filter` column becomes nullable, so a row written by an older build carries a non-null placeholder where the new code expects absence to mean "no filter". Separate from the bump in the sort change below it: each is its own stored-format change, and the entity check compares a PR against its base rather than against the whole stack.

`queryUsers` and `queryBannedUsers` declare `filter_conditions` as a required
field (`validate:"required"` in the backend's request payloads). go-playground
reads that as non-nil, so `{}` passes and an omitted key is rejected.
Making `filter` nullable turned every `Filter.empty()` caller into a `null`,
which dropped the key entirely — a 400 on mention autocomplete with
`mentionAllAppUsers`, and on the initial directory load of the sample app's
three user-picker screens. `queryMembers` already sent `filter ?? {}`;
`queryChannels` genuinely has no such constraint and stays conditional.
Also rewords the changelog line about the withdrawn negative operators, which
read as though the sample app filters client-side. It does not — it shows
everyone the query returns.

This PR is where `stream_core` stops being a hosted constraint, and three documents kept asserting it is one. The `openapi-codegen` skill is the dangerous one: it is auto-loaded, and its own trigger is "changing the `stream_core` constraint", so an agent doing exactly this work was handed a file saying the dependency is hosted with no overrides, and that publishing is unblocked. It now describes the SHA pin and says a git dep under `dependencies` makes the package unpublishable until it is restored. Also fixes this phase's definition of done, whose first item was an unticked box reading "`Filter.notEqual`, `notIn` and `nor` are `@Deprecated`" — the inverse of what the PR does. An unticked box reads as assigned work, so anyone closing out the phase would have re-added three operators the API is withdrawing. And `UPSTREAM.md` still named `$nor` as the top thing to push upstream, which this PR deletes. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
`ChannelModel.copyWith` cast `muted`, `blocked`, `disabled` and `hidden` out of a replacement extra-data map with `as bool?`, so a consumer-authored non-boolean threw where the matching getter answers null. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

…fely `UserFilterField` had no `email` and `MemberFilterField` no `notifications_muted`, though both are declared columns — `mq/user/user.go:61` maps `email` to `custom->>'email'` with `$eq`/`$in`, and `mq/member/member.go:197` takes `notifications_muted` with `$eq`. The member side already declared the user's email as `user.email`, so the user side lacking it read as an oversight rather than a decision. Every typed field backed by extra data now goes through `safeCast` instead of handing the raw `Object?` to the comparison. The sort registry already did this (`user.dart:428`); the filter registry did not, so a server value of an unexpected type would have compared as itself rather than as absent. `ChannelFilterField.custom` and `ThreadFilterField.custom` name the fields the server computes per request — `joined`, `has_unread`, `invite`, `distinct`, `app_banned` — which are reachable only that way. They were listed in the phase doc and nowhere a caller would look. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The sort registry pins its remote names and says why: a field the server rejects fails the request at runtime, and no other test catches it. The filter registry had the same test until it was dropped as duplicated bookkeeping. Filters are the worse of the two cases. `mq/parser.go:270-277` treats an unrecognised key as custom data wherever the resource declares a custom container — channel, user, member, poll and thread all do — so a typo does not fail the request. It compiles to `custom->>'typo'`, matches no row, and returns an empty page that reads like a legitimately empty result. The objection that killed the old test still stands: a hand-written list stays green when the API grows a field. It only ever covered the other direction, which is the one that ships a silent bug.

The migration guide told callers to pattern match on `EqualOperator` and friends. The barrel exports neither it nor any other subclass, so that does not compile — `stream_chat.dart` shows `Filter`, `FilterField`, `FilterOperator` and two abstract bases, and the bases are there only because `searchQueryLength` needs them. `stream_feeds` re-exports core wholesale, so every operator class is public there, and still nothing in it pattern matches: introspection is `toJson()` in all 36 places it reads a filter. Both docs now say `toJson()`, and the allowlist says why the two exceptions exist. `DEFERRED.md` is named as the authority by this branch's `UPSTREAM.md` and by the codegen skill, and it carried three rows this branch falsifies: adopting core's `Filter`/`Sort` "blocked on core gaining `$nor`", which this branch does by dropping `$nor`; deciding the fate of `Filter.custom`/`raw`/`empty`, decided; and the platform detector blocked on a release carrying `debugCurrentPlatformOverride`, which the pinned SHA already has. The row every other one folds into — restoring hosted constraints — was missing entirely, which is what `UPSTREAM.md` deleted its own list in favour of. The codegen skill's "there is no release blocker" now leads with the thing that is true for the reader it is written for: the pin makes three packages unpublishable. The generated client needing nothing past 0.5.0 is a separate sentence, not a headline. Phase 08 gains what its own field table cannot carry: the spec is a field oracle, not an operator oracle, since `mq/config.go:189` strips only internal operators and `$ne`/`$nin`; and core's evaluation operators require a `String`, so the array getters it credits work for `$eq`/`$in` but not for the `$autocomplete` on `member.user.name`.

…where it waits Two leftovers from the previous commit. The `CurrentPlatform` row sat under "Blocked on something outside the repo" reading "nothing any more", which is the same shape of staleness that pass was meant to remove; it waits on the restore row, so it belongs under "Waiting on a decision or a later phase". Phase 08's definition of done still had unticked boxes for work this branch completed — deleting `filter.dart` / `sort_order.dart` / `comparable_field.dart` behind the allowlist, and the registries themselves. An unticked box reads as assigned work, which is the failure `93abff8f4` called out for the `@Deprecated` item. `location_coordinates.dart` is genuinely still exported, so it splits into its own row instead of being ticked with the rest.

🎯 Goal
Filterwas one class with a nullableoperatorstring and akey. Core models it as a sealed type over a per-model field registry — the same registry that drives sorting — so one declaration serves both the server query and client-sideFilter.matches.🛠 Implementation details
Filter.equal('type', 'messaging')becomesChannelFilter.equal(ChannelFilterField.type, 'messaging'). A field the SDK does not model is reached withChannelFilterField.custom('my_field').Filteris sealed and no longer exposeskey,valueoroperator; read it withtoJsonor pattern match. It also compares by identity now, so comparetoJson()where you compared filters.Filter.notEqual,notInandnorare removed — the API is withdrawing$ne,$ninand$nor. A caller that excluded someone now excludes them client-side, or shows them. The sample app shows them: its directory and member picker no longer hide the signed-in user or existing members.Filter.empty()is removed; everyfilterargument is nullable. This matters onqueryThreads, where the API widens an omitted filter but not an empty one.Filter.customis removed in favour of a registry'scustomfactory;Filter.rawtakes its map positionally and is not validated.stream_coreandstream_core_flutternow resolve from a pinned commit rather than a hosted constraint, because this PR needsFilter.raw, which is not in published 0.5.0. Pinned to a SHA rather than a branch:stream_core_flutterreachesstream_corethrough the same clone, and pub counts a branch ref and a resolved SHA as two sources of one package, which fails to solve.invalid_dependencyis silenced for the same reason — a git dependency makes these packages temporarily unpublishable, which is true and intended.☑️ Verification
melos run analyze,melos run formatandmelos run test:dartpass, verified in a clean worktree with no sibling checkout in scope — the same conditions CI runs under.Filter fields were verified against the backend's own query layer, not the published spec — the spec still advertises operators the API rejects.
