Preserve whole-tuple inference across wrapped and async sources - #7641
Whole tuple rows now keep their first-argument boundary when optional, params, or collecting-array tails are omitted. Generated and reflection discovery retain the same inferred method instantiations alongside explicit types, including derived TestDataRow<T> records and Task/ValueTask/async-enumerable sources.
This extracts only the whole-row portion of closed#7631 from preserved head 2a1cc3753c847cfc3393accc5b8adae517e75895. Strict matching enforces repeated bindings and constructed-tuple invariance; ordinary spread columns keep last-column inference. Sole-tuple conversion and reconstruction retain existing behavior. The derived-row and async-wrapper findings transferred from threads PRRT_kwDOLJDcx860AwXk and PRRT_kwDOLJDcx860AxWl are covered by regressions. Analyzer false positives remain tracked in #7622 and matcher maintainability in #7588.
Validation:
Full core-generator snapshot suite: 351 passed, one existing skip; reviewed and committed the new 53-entry verified snapshot.
Helper tests: 14 passed.
Shared focused fixtures: identical 53 method instantiations and outcomes in generated and reflection modes; 44 passed, nine intentional failures preserve unsupported explicit long whole tuples with tails.
Existing optional/trailing tuple fixtures: 55 passed in each mode.
Native AOT publish succeeded (osx-arm64, net10.0); focused execution has the same 53 method instantiations and outcomes. Existing dependency and unrelated fixture trimming warnings remain.
Engine integration expectations added for CI; suite not run locally per AGENTS.md.
Follow-up Native AOT publish succeeded (osx-arm64, net10.0); all 59 focused cases have the same 48 passing and 11 intentional failing outcomes. Existing dependency/unrelated fixture warnings remain.
Existing optional-tuple fixture: 29 passed in each generated and reflection mode.
Summary by CodeRabbit
Bug Fixes
Fixed test discovery and data binding for tuple-based data rows, including nested value and reference tuples.
Improved handling of tuple rows with optional or params arguments, repeated generic types, and explicitly specified generic types.
Fixed type inference for data sources provided through properties, fields, and supported synchronous or asynchronous sources, including wrapped and derived row types.
Improved tuple handling when rows are passed as a single value or spread across multiple test parameters.
Ambiguous-overload review follow-up (39e346f): both reflection inference lookups now return no inferred types when source overload resolution is ambiguous. Added two targeted unit regressions: both fail on the previous code and pass with the fix; explicit method instantiation is preserved. No generator output changes. Engine integration tests remain for CI per AGENTS.md.
Tuple matching and row binding now support whole-tuple method inference across generated and reflection discovery. The changes also update data-row wrapper handling and add regression tests for tuple shapes, generic bindings, optional arguments, and asynchronous data sources.
A cached matcher checks open tuple shapes and consistent generic bindings. Runtime helpers preserve compatible whole-tuple rows and find TestDataRow<> through base classes. Tests cover matching, row binding, derived wrappers, and optional arguments.
Generated inference recognizes Tuple and ValueTuple shapes. It matches compatible whole rows before spreading tuple elements and unwraps derived data-row wrappers. Tests cover generic bindings, wrappers, and synchronous or asynchronous sources. The documentation describes matching rules and implementation points.
Reflection discovery resolves declared data-source members and row types. It infers from a whole tuple when compatible, otherwise maps tuple elements positionally. Generic mapping handles nullable parameters and matching-rank arrays. Ambiguous source lookup returns no inference. Tests check inference behavior and discovered test counts.

Explanation
Issue #7638 is the active linked issue. Closed issue #7631 provides context only. The change implements whole-tuple boundary handling for optional, params, and collecting-array tails. It enforces repeated generic bindings and constructed-tuple invariance. It preserves inferred instantiations with explicit types across direct, wrapped, derived TestDataRow<T>, reference-tuple, Task, ValueTask, and async-enumerable sources. Reflection resolves declared property and field types and rejects ambiguous source inference. The added fixtures, helper tests, snapshots, documentation, and engine expectations cover the required behavior. The summary reports matching generated and reflection outcomes and Native AOT verification.
Full details: Out of Scope Changes check
Explanation
The changed production files are the files named by issue #7638 for whole-row matching, row unwrapping, source-wrapper normalization, and generated or reflection inference. The added fixtures, helper tests, snapshots, documentation, and engine expectations support the issue requirements. The ambiguous-overload regression is directly related to safe source inference. The evidence shows no sole-tuple reconstruction change or instance-source implementation. Issues #7622 and #7588 remain referenced as separate follow-up scope.

Thanks for using CodeRabbit! It's free for OSS, and your support helps us grow. If you like it, consider giving us a shout-out.
A rabbit checks each tuple row, Where whole-row matches help types grow. Wrapped rows and async streams align, Optional tails keep their design. The test burrow marks the flow.
I read the diff and found no blocking correctness problems. I did not build the PR or run its tests.
What looks good
The generator and runtime matchers (MatchesOpenRowType and TupleHelper.MatchesType) follow the same rules. Repeated generic bindings must agree, constructed tuple arguments are compared by exact type, and array rank is checked. This is the parity AGENTS.md asks for in metadata collection.
The derived TestDataRow<T> walk is done the same way on both sides: the base-type loop in the generator and GetInnerDataType at runtime.
Narrowing the whole-tuple rule to omitted optional, params, or collecting-array tails, and keeping last-column inference for ordinary spread columns, limits the behavioral change.
The PR description says the tests cover the same shapes in generated and reflection modes, plus Native AOT.
Suggestions (non-blocking)
Assignment inside the condition. In InferTypesFromMethodDataSourceRowType, wholeTupleBindings is assigned inside the && chain that computes receivesWholeTuple. It is only read when that chain is true, so it works. It is easy to break in a later edit, though. Declare the dictionary before the chain, or move the check into a helper such as TryMatchWholeTuple(..., out bindings). That also helps with the matcher maintainability tracked in Simplify declared row shape and generic inference policy inputs #7588.
Duplicated matcher logic. The two matchers are mirror images by hand, and the // Mirrors generator MatchesOpenRowType comment is the only link between them. This is fine for now since Simplify declared row shape and generic inference policy inputs #7588 tracks it. A shared table of shapes in the unit tests, run against both implementations, would catch drift sooner.
Unbounded cache.OpenTupleMatches in TupleHelper is a process-lifetime ConcurrentDictionary keyed on (parameter, row) types. It is bounded by the number of distinct types, which is small in practice. Both call sites sit on a per-row path, so the cache is reasonable. Ignore this if you want to keep it as is.
Snapshot size. The new 5.3k-line verified snapshot is hard to review by hand. If one smaller fixture covers each rule in the docs table, the snapshot would be easier to maintain, and the large runtime fixture could stay.
Open whole-tuple matching reads TupleArgument.TupleType, preserving mutable initializer elements in both value and reference tuples.
Reflection's declared-row inference now uses GetDeclaredMemberType, the same member resolution as source invocation, so property and field sources supplement explicit types with inferred cases.
Validation: net10.0 build passed; all #7638 fixtures produce the same 59 cases in generated and reflection modes (48 passed, 11 intentional unsupported explicit-type failures). The two mutable regressions pass; property and field sources each discover and pass their inferred int case alongside their intentionally failing explicit long case. Added engine integration expectations for CI; that suite was not run locally per AGENTS.md.
Native AOT publish and execution also agree on all 59 cases (48 passed, 11 intentional failures). Existing optional-tuple fixtures passed 29/29 in each mode.
Claude's non-blocking suggestions are dispositioned as follows: retain the conditional binding assignment and handwritten matcher adapters in this correctness PR; #7588 already covers named helpers and shared policy/test improvements. Retain the type-pair cache because it avoids per-row matcher allocations and its keys represent encountered type pairs. Retain the existing snapshot coverage because each entry pins a different generated method instantiation; reducing it would lose that coverage. These suggestions do not block this PR.
I read the source changes in the generator, TupleHelper, DataSourceHelpers, TestDataRowUnwrapper, DataUnwrapper and ReflectionTestDataCollector. I did not build or run anything. The approach looks right, and I found no blocking correctness bugs.
What looks good
The generator's MatchesOpenRowType and the runtime's TupleHelper.MatchesType have the same semantics: repeated generic parameters must bind to the same type, constructed tuple arguments are invariant, and arrays are matched by rank. Generated and reflection discovery should therefore infer the same instantiations.
Reflection now resolves the data source member with GetDeclaredMemberType and GetDeclaredRowType, the same lookup as invocation. That also fixes properties, fields and async wrappers, which the old GetMethod(... DeclaredOnly) lookup missed.
Walking BaseType for derived TestDataRow<T> records is applied on both the generator side and the runtime side.
The new snapshot and the _7638 fixtures cover both modes. The PR description also reports an AOT publish.
Suggestions (non-blocking)
Duplicated matcher. The matching logic exists twice, once over ITypeSymbol and once over Type, and the whole-tuple detection (receivesWholeTuple) is written separately in the generator and in ReflectionTestDataCollector. The PR already points to Simplify declared row shape and generic inference policy inputs #7588. A drift between the two is the main long-term risk, since AGENTS.md requires identical behaviour in both modes. I'd extract the shape decision into one small predicate in each side, with the same name and a doc comment, and add a test that feeds one table of cases to both sides.
Cache lifetime.TupleHelper.OpenTupleMatches is a static ConcurrentDictionary<(Type, Type), bool> that holds Type references for the life of the process. That is bounded by the number of distinct test types, but it can pin types from collectible load contexts. A ConditionalWeakTable or a per-discovery cache would avoid that. The cost is probably small, so a comment may be enough.
Hot-path allocations in the generator.testMethodParams.Skip(1).All(...) and the new Dictionary are allocated for every row of every generic method. A for loop and a lazily created dictionary would avoid this. The same applies to the Skip(1).All in ReflectionTestDataCollector.
Fragile parameter == parameters[^1]. In reflection this compares ParameterInfo by reference. That works, but comparing parameter.Position == parameters.Length - 1 states the intent more clearly.
Narrow receivesBareReferenceTuple heuristic. This special case requires a GenerateGenericTestAttribute on the method. The reflection side uses !rowType.IsValueType with a single generic parameter and no such attribute check. Please confirm the two sides agree for a method that has [MethodDataSource] but not [GenerateGenericTest].
Overall this is a solid fix and I'd merge it after considering (1) and (5). The Engine integration tests only run in CI, so I'd wait for them to pass.
Disposition of the latest Claude suggestions on 4780de8:
Bare reference tuple parity: the reflection helper is reached through InferMethodInstantiationsFromDataSources only after ResolveGenericMethodInstantiations has checked GenerateGenericTest attributes. With no such attributes, it calls ResolveDeclaredTypedSourceInstantiations and yields before that helper (ReflectionTestDataCollector.cs:2035–2046). Its helper therefore has the same effective attribute precondition as the generator's receivesBareReferenceTuple check. The apparent mismatch is not a discovery behavior difference.
Retain the existing process-lifetime type-pair cache in this correctness change, consistent with the surrounding reflection caches; collectible-context cache ownership is a separate engine-wide concern.
Retain the last-parameter identity check: each parameter comes from the same parameters array, so reference identity is reliable. Position comparison would be a non-blocking readability change.
Both required reviewers have positive verdicts for this head, and all review threads are resolved. Promoting the draft for CI; Engine integration validation remains required in CI.
Marked ready with head unchanged at 4780de8. Promotion started Claude review run 42016004825 and CI runs including .NET 42016004271 and AOT/Engine tests 42016004350. Auto-merge is not armed yet: read the promotion Claude review and require its success before running Enable-AutoMerge.ps1. No code changes were needed in this unit.
I couldn't run the automated code-review skill, so this is a manual read. I read TupleHelper.cs in full and skimmed the PR description and file list. I did not read the generator or engine diffs line by line.
What looks good
TupleHelper.MatchesType does what its comments say. It binds repeated generic parameters consistently and treats constructed tuple type arguments as invariant. The ConcurrentDictionary cache keeps the reflection cost out of the hot path.
AppendTupleElements only flattens the storage Rest slot, so a tuple in an Item slot stays one element. It caches the member lookups.
The PR adds snapshot tests, helper unit tests, TestProject fixtures covering generated and reflection modes, and Engine integration tests. That fits the AGENTS.md rule that both discovery modes behave identically. The description also reports a Native AOT publish.
Suggestions
Duplicated matching logic. The comment on MatchesType says it mirrors the generator's MatchesOpenRowType, so the same rules now live in two places. Nothing but a comment keeps them in sync. Simplify declared row shape and generic inference policy inputs #7588 already tracks matcher maintainability. A shared fixture, or a unit test that feeds the same type pairs to both matchers and asserts the same result, would catch drift sooner than the comment will.
Cache lifetime.OpenTupleMatches is keyed on (Type, Type) and lives for the whole process. That is fine for a normal test run. Under a collectible AssemblyLoadContext or a long-lived host, it keeps the types alive. It is probably acceptable, but the code comment could say so.
Dead-looking overload. The #if NET overload IsTupleType(ITuple) always returns true. If it predates this PR, ignore this. If it doesn't, it's worth a look.
No blocking issues from what I read. I'm relying on CI for the Engine tests, as AGENTS.md says.

Run 42016004825 completed successfully; the earlier wait no longer applies. Fixed the new ambiguous-overload finding in 39e346f and resolved its thread. Both targeted regressions fail without the fix and pass with it (2/2).
Promotion Claude suggestions: matcher parity work remains tracked in #7588; retain the type-pair cache for the reasons already recorded above. The IsTupleType(ITuple) overload predates this PR (present on origin/main). CodeRabbit's aggregate docstring percentage is a non-blocking style suggestion: retain focused comments and existing XML summaries rather than adding boilerplate to test fixtures to meet that percentage.
Fresh CI and reviews are required for the new head. Auto-merge remains unarmed until that review gate passes. Engine integration tests were not run locally per AGENTS.md.
Review of #7641 (whole-tuple inference). I read the source diff and skimmed the tests and snapshot. I did not build or run anything. I found no blocking correctness problems. The generator and reflection paths follow the same rules: strict matching with repeated-binding consistency, invariance for closed constructed tuples, fallback to spreading, and last-column inference for ordinary columns. Suggestions (non-blocking): (1) MatchesOpenRowType (Roslyn) and TupleHelper.MatchesType (runtime) are the same algorithm written twice, so a table-driven parity test would catch drift until #7588 lands. (2) TupleHelper.OpenTupleMatches is a process-lifetime static cache keyed on Type pairs. It pins types from collectible AssemblyLoadContexts and never shrinks, so consider per-method caching, a ConditionalWeakTable, or dropping it, since a miss only costs one Dictionary allocation. (3) The omittable-tail predicate (Skip(1).All(...)) now exists in the generator, the reflection collector and DataUnwrapper.RemainingDataParametersAreOmittable. One shared helper would stop generated and reflection behavior diverging. (4) GetTupleElementTypes now accepts ValueTuple by name with arity up to 8. Please confirm an 8-argument ValueTuple with a TRest slot is not misread as 8 flat elements, and add a fixture if it is not already covered. Verdict: the design is sound and the PR description is thorough. These are follow-ups, not blockers, and CI (including TUnit.Engine.Tests) is the remaining gate.

The earlier wait on run 42016004825 is complete. Current head 39e346f has a successful Claude review, a completed Codex review with no findings, and passing CI including both Engine tests and AOT jobs.
Disposition of the latest non-blocking Claude suggestions:
Matcher parity tests and extraction of the omittable-tail predicates remain follow-up maintainability work under Simplify declared row shape and generic inference policy inputs #7588. Retain the matching predicates in this correctness change; generated Roslyn symbols and runtime reflection types require separate adapters.
Retain the type-pair cache for the reasons recorded in the previous disposition; broader collectible-load-context cache ownership needs an engine-wide approach.
The eight-argument ValueTuple concern is already handled: TestMetadataGenerator.GetTupleElementTypes uses Roslyn TupleElements for tuple symbols; its named-type fallback takes only the first seven arguments and recursively flattens TypeArguments[7] (lines 7286–7303). Reflection GetValueTupleElementTypes likewise recursively flattens arguments[7] (lines 3222–3243). Neither treats TRest as an eighth flat element. No fix is needed.
CodeRabbit confirmed the ambiguous-overload fix in its resolved thread; no further change was requested. Its docstring percentage warning retains the previously documented non-blocking disposition. All review findings have a disposition and every thread is resolved. Proceeding through the fresh merge gate without code changes.

Whole tuple rows now keep their first-argument boundary when optional, params, or collecting-array tails are omitted. Generated and reflection discovery retain the same inferred method instantiations alongside explicit types, including derived
TestDataRow<T>records and Task/ValueTask/async-enumerable sources.This extracts only the whole-row portion of closed #7631 from preserved head
2a1cc3753c847cfc3393accc5b8adae517e75895. Strict matching enforces repeated bindings and constructed-tuple invariance; ordinary spread columns keep last-column inference. Sole-tuple conversion and reconstruction retain existing behavior. The derived-row and async-wrapper findings transferred from threadsPRRT_kwDOLJDcx860AwXkandPRRT_kwDOLJDcx860AxWlare covered by regressions. Analyzer false positives remain tracked in #7622 and matcher maintainability in #7588.Validation:
longwhole tuples with tails.Closes #7638
Review follow-up:
TupleArgument.TupleTypewhen matching open whole tuples with mutable initializer elements.Summary by CodeRabbit
paramsarguments, repeated generic types, and explicitly specified generic types.Ambiguous-overload review follow-up (39e346f): both reflection inference lookups now return no inferred types when source overload resolution is ambiguous. Added two targeted unit regressions: both fail on the previous code and pass with the fix; explicit method instantiation is preserved. No generator output changes. Engine integration tests remain for CI per AGENTS.md.
