fix: Hot reload now patches partial-type bodies that use an internal member of a type the reload was not given

[hatayama]

Summary

• A method or property getter on a partial type is now patched when its body uses an internal field, property or method of another compiled type of the same assembly that the reload was not given, for example Host.InternalValue(), new Host().InternalField, host?.InternalCall() or an inherited this.InternalCall(). Until now such an edit was skipped with a reason claiming that a part generated at compile time was missing.
• A file brought back to re-bind its active patches is re-applied in the same case instead of being skipped.
• Uses hot reload cannot patch in place stay skipped, now with a reason that says why and what to change.

User Impact

• Before: the edit was reported as Skipped with "None of this partial type's source files known to hot reload declares that name: a part generated at compile time is not visible to it ...", although the member is declared and only internal. The edit did not take effect until uloop compile, while the same body on a non-partial type was patched.
• After: these edits are patched, and the next call returns the edited value. When the use cannot be patched in place (a bare name, a method passed as a delegate, a use inside a lambda, local function, query, iterator or async method, a body where a lambda, local function or query works with the member's result, or a body patched through a delegating shim), the reason says the member is internal to that type, lists the forms hot reload can patch, and suggests qualifying a bare name with this. or the type name, or running uloop compile.

Cause

• The worker binds bodies in a compilation that imports referenced assemblies through their public surface only, so an internal member of a compiled type does not exist there: the error is CS0117 / CS1061 / CS0103, not CS0122.
• The partial-type guard added in feat: Hot reload now applies method edits on partial types #3184 reads those errors as a part it cannot see. The guard for a brought-back file skips on any error in the body; it predates feat: Hot reload now applies method edits on partial types #3184 and hits non-partial types as well.
• The shim compile, however, references the target assembly with every member public, and code copied into the patched method runs without access checks. These uses therefore bind and run there, which is why the same edit on a non-partial type was already patched.

Changes

• New worker check UnpassedInternalMemberUse. For an error that reports a missing member, it looks the name up in the target assembly read with every member visible, on the receiver's type (or the enclosing type for a bare name). It walks base types that belong to the target assembly and that the run does not declare from source. Types are looked up by reflection name, because the two compilations hold different symbols. It reports the internal member it found and whether the patched method itself runs the use.
• A use also stays out when any lambda, local function or query in the body has an expression whose type the worker could not resolve. The worker reports no error for a use that follows an unresolved value, such as the result of an internal member, so it cannot tell whether such a closure reaches an internal member. A closure runs in the shim assembly, where that use would throw. The method's own statements still go through, because they run inside the patched method.
• Partial-type guard: a use that can be patched in place passes, and the guard goes on to the next error. A use that cannot is skipped with the new reason MethodTransformUnpassedInternalMemberOutOfReach. Any other missing name keeps today's reason.
• Brought-back file guard: the body passes only when every error in it is a use that can be patched in place. Otherwise the guard skips with exactly today's reason.
• Both guards cover getters too; TrySkipPropertyGetterByDecision now receives the target assembly.
• For value?.Name the compiler reports the whole .Name member binding rather than the name, so the check unwraps it. This came up when the conditional-access case was made to pass.
• The new reason also says that a lambda, local function or query that works with a value hot reload could not resolve, such as the member's result, keeps the whole body out.
• Skill reference scope-and-limits.md gains two Skipped rows. The generated .claude/ and .agents/ copies are regenerated.

What passes and what stays skipped, and the evidence

These are uses of an internal member of an unpassed compiled type of the same assembly. "Measured" means an investigation run with the guards removed.

Use	Before	After	Evidence
Field, property or invoked method written with a receiver (Type.X, expr.X, expr?.X, this.X, Outer.Nested.X, inside nameof) in the method's own statements	Skipped	Patched	Measured: identical to a non-partial type (Patched, transplant, the call returns the edited value). A brought-back file re-applies and keeps the edited value
Bare name X() (inherited internal member)	Skipped	Skipped, new reason	Measured: the shim compile fails with CS0103 and the whole file becomes Failed. The shim qualifies a bare name only when the worker binds it
Inside a lambda or an iterator	Skipped	Skipped, new reason	Measured: Patched, then MethodAccessException on the first call. Closure classes and state machines are JIT-compiled inside the shim assembly with access checks
Inside a local function, query or async method, or in a body patched through a delegating shim	Skipped	Skipped, new reason	From the code: these run inside the shim assembly the same way. Local functions and queries are collected as closures, async methods are state machines, and a delegating shim runs the whole body there
Method passed as a delegate (not invoked)	Skipped	Skipped, new reason	Not run either way, so it stays skipped
A lambda, local function or query works with the member's result (a var local holding it, a lambda parameter typed by it, a query over it)	Skipped	Skipped, new reason	Measured with this PR's tests before the closure check: the worker saw only the error on the member itself and emitted the body. The run reported Patched, and the call threw MethodAccessException or FieldAccessException
The member's result used in the method's own statements (Type.InternalSelf().InternalValue())	Skipped	Patched	Measured: Patched, and the call returns the edited value

Inputs that are not axes: static or instance members and reads or writes of fields and properties behave the same in the investigation; #1 covers them through test cases. Whether the unpassed type is partial or wrapped in #if does not matter either; two worker tests keep both. Generic receivers are looked up through OriginalDefinition, but no fixture has such an internal member. protected internal, private protected and public members of internal types already bind in the worker and never reach the guards.

What did not change

• Existing methods of passed non-partial types: there is still no guard, including the gaps listed under Not covered.
• Added methods still skip with AddedMethodBodyUnbound.
• The brought-back file guard's reason text when it skips.
• The worker's binding compilation, which still imports only the public surface.
• Guard order: brought-back file guard then partial-type guard for ordinary methods, and the reverse for getters.

Verification (local)

Pull requests to the integration branch do not trigger the main PR CI, so the checks below were run locally on this branch.

• uloop compile: 0 errors, 0 warnings.

• Red before the worker change: 31 of the new or rescoped tests failed (worker 20, end-to-end 11), and the tests predicted to pass passed. The reason-text case failed until the reason was added.

• Second round, for closures over an internal member's result (found in review): before the closure check, 8 tests failed. The 6 worker tests saw the body emitted instead of skipped, and the 2 end-to-end tests saw Patched followed by FieldAccessException or MethodAccessException on the call. The 3 pins for the result used in the method's own statements passed. The reason-text case failed until the new sentence was added.

• uloop run-tests (regex filter), all on the final code:

  • The three target classes all passed inside the two runs below: TransformWorkerPartialTypeTests (60), HotReloadWorkerReasonTextTests (145) and HotReloadUnpassedInternalMemberE2ETests (41).
  • Surrounding unit classes: 801/801 passed. These are every hot-reload test class that mentions the brought-back file guard, the partial-type reason or property getters: TransformWorkerPartialTypeTests, HotReloadWorkerReasonTextTests, HotReloadApplyOutcomeTests, HotReloadCompileFallbackDeciderTests, HotReloadGroupProcessorTests, HotReloadOrchestratorTests, HotReloadToolTests, HotReloadWorkerNoticeAppenderTests, TransformWorkerAddedEventTests, TransformWorkerAddedMemberAccessTests, TransformWorkerBindingSplitTests, TransformWorkerClientTests, TransformWorkerRetainedDeclarationTests, TransformWorkerSkippedWriterWarningTests.
  • Surrounding end-to-end classes: 121/121 passed. These are HotReloadUnpassedInternalMemberE2ETests, HotReloadAddedEventE2ETests, HotReloadAddedMemberInvocationCountE2ETests, HotReloadBindingSplitE2ETests, HotReloadCrossFileE2ETests, HotReloadDefaultSelectionEnumLeaveOutE2ETests, HotReloadFieldOnlySiblingE2ETests, HotReloadIntroducedTypeSameReloadReferrerE2ETests, HotReloadSiblingCompanionE2ETests, HotReloadStaleRowSiblingE2ETests, HotReloadPartialTypeE2ETests.

• Mutations: each was applied to the committed tree, the classes were run, and the file was restored with git checkout. git status --porcelain was empty after each. In every run only the tests listed here failed. m1 to m10 first ran on the first-round code. On the final code, m2 to m10 were re-run and failed exactly the same tests, and m1 and m11 were run there as well.

  #	Mutation	Failed
  m1	Drop the closure check	First-round code: Skip_..._WhereItCannotBePatchedInPlace_SaysWhy (Lambda, LocalFunction, Query), Skip_SiblingBroughtBack_UsingInternalMemberInsideALambda_KeepsTheSiblingReason. Final code: an equivalent mutation, nothing fails, because the check for a closure over an unresolved value (m11) catches the same forms. With m1 and m11 applied together, 15 tests fail: those 4, the 8 m11 tests, and 3 end-to-end lambda cases (InternalStaticMethodInLambda, InternalInstanceMethodInLambda, InternalStaticMethodInLambdaReadingOwnPrivateField). The check stays so that the rule matches the reason text and does not rely on how error types propagate
  m2	Drop the async / iterator check	Same test (Iterator, Async)
  m3	Drop the delegating-shim check	Skip_PartialTypeGetterWithALambdaReadingAPrivateMember_UsingInternalMemberDirectly_SaysWhy
  m4	Drop the receiver requirement	Same test as m1 (BareName)
  m5	Accept any accessibility	Skip_PartialTypeBodyUsingPrivateMemberOfUnpassedType_KeepsTheMissingNameReason
  m6	Stop skipping types the run declares	Skip_PartialTypeBodyUsingThisInternalMemberOfAPartNotAmongTheAssemblySources_KeepsTheMissingNameReason
  m7	Partial-type guard passes at the first patchable use instead of checking the next error	Skip_PartialTypeBodyUsingInternalMemberNextToAnUnresolvedName_NamesTheUnresolvedName
  m8	Brought-back file guard decides on the first error only	Skip_SiblingBroughtBack_UsingInternalMemberNextToAnUnresolvedName_KeepsTheSiblingReason
  m9	Join nested type names with . instead of +	Run_PartialTypeBodyUsingInternalMemberOfANestedUnpassedType_EmitsEntry, E2E Run_PartialTypeBodyUsingInternalMemberOfUnpassedType_PatchesBehavior("InternalStaticMethodOfNestedType")
  m10	Accept a method that is not invoked	Same test as m1 (MethodPassedAsDelegate)
  m11	Drop the check for a closure over an unresolved value	The 8 second-round tests: Skip_..._WhereItCannotBePatchedInPlace_SaysWhy (LambdaUsingTheResult, LambdaParameterFromTheResult, LocalFunctionUsingTheResult, QueryOverTheResult), Skip_PartialTypeGetterWithALambdaUsingTheResultOfAnInternalMember_SaysWhy, Skip_SiblingBroughtBack_WithALambdaUsingTheResultOfAnInternalMember_KeepsTheSiblingReason, and E2E Run_PartialTypeBodyUsingInternalMemberOfUnpassedType_IsAppliedAsEditedOrSkipped (2). The 3 pins still passed

• scripts/sync-tool-docs.sh --check: the catalog matches the skill tables.

• go run ./cmd/check-skill-size (in cli/release-automation): no SKILL.md over the limit.

• Generated copies: .claude/ and .agents/ differ from the base only by the same two rows, and they are byte-identical to the source file.

• scripts/check-code-complexity.sh (fail on exceeded): 0 Go issues, no CA1502 finding above 15.

• scripts/check-file-length.sh (fail on exceeded): no file over 500 SLOC.

• scripts/check-dead-code.sh with the CI arguments: exit 0, PublicCandidate 36 (limit 37), and no new symbol is listed.

• git merge-tree against the integration branch head after fix: Hot reload no longer patches unchanged methods when it runs right after a domain reload #3195, which also includes fix: Send the compile again when Unity lost the request or rejected it as already compiling #3192 and fix: Hot reload now says to run uloop compile when an added member uses a name generated at compile time #3193, reports no conflict. fix: Hot reload now says to run uloop compile when an added member uses a name generated at compile time #3193 changes only the added-method reason text, and no test here asserts it. The tests have not been run on the merged state.

Not covered

1. An internal member of a type in another assembly, used through InternalsVisibleTo, stays Skipped from a partial type's body and from a brought-back file. A passed file of a non-partial type is still Patched. This difference existed before and is not closed here: the shim compile publicizes only some references, and the worker does not know which.
2. A non-partial type that uses an internal member inside a lambda or iterator is reported as Patched and then throws MethodAccessException. This gap predates this change and is not fixed here.
3. A bare name of an inherited internal member on a non-partial type fails the file in the shim compile, as before.
4. Generic receivers have no fixture. Internal events and methods passed as delegates are kept skipped rather than patched.
5. A body where a lambda, local function or query works with any value the worker could not resolve is skipped, even when the closure itself would be safe.
6. A use that follows an internal member's result in the method's own statements is invisible to the worker. It runs inside the patched method, so it works even when it is internal. If it reaches a non-public member of an assembly the shim compile does not publicize, though, the shim compile fails the whole file.

Change: Bug fix

Merge Risk: 🔵 Low · up to 9f583

A hot-reload edit calling an incompatible internal overload can fail during shim compilation instead of being skipped. This is a bounded case, but overload applicability should be checked before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 9f583

The newly accepted uses remain restricted to internal members of the target assembly and execution inside an existing patched method. No new privilege escalation was established. Confidence is limited by incomplete verification of concurrent reloads and interrupted recovery.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The incremental execution scope is existing selected methods and getters using internal members of the target assembly, including carried-in sibling bodies. These patches execute through the existing Unity Editor workflow; assembly matching is an ownership restriction, not a process sandbox.

Trust Boundaries and Controls

• observed — The new recovery path excludes members outside the target assembly, source-declared types and non-internal members. Bare names, non-invoked method uses, closures, async or iterator execution, and delegation are rejected when they cannot execute in place. These controls bound the changed classifier; they do not establish outer caller authorization.

Resilience and Maintainability Implications

• observed — The added sibling-reload test asserts that an already patched caller keeps returning its edited value after another file reloads, whether reapplication reports Patched or Skipped. This covers normal repeated reapplication, not incompatible-overload failure, concurrent reloads or interrupted recovery.

🟡 Minor · Check overload applicability before allowing the body… · UnpassedInternalMemberUse.cs:146-183

Packages/src/Editor/FirstPartyTools/HotReload/TransformWorker~/UnpassedInternalMemberUse.cs:146-183
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Check overload applicability before allowing the body through.

If a partial body calls receiver.Read(value) with no applicable extension method, and the omitted compiled type only has internal Read(), the worker reports CS1061. The name-only lookup selects Read() and marks the invocation patchable without checking its arguments. The partial guard continues, but the shim exposes the same zero-argument signature, so the shim compile rejects the call. Require the actual invocation to bind to a compatible target-assembly overload before continuing the guard.
