Summary

  • Tool migration now removes the legacy PlayerLoopTiming argument from inherited calls that a derived class makes without base. (Run(..) and this.Run(..)), and from base.Run(..) calls that reach the method through an intermediate class. A call on another object (GetOther().Run(..)) inside the class that declared the method keeps its argument. Methods that return arrays are covered too, and a delegate local or lambda parameter that shares the method's name keeps its arguments.
  • More Editor paths now have EditMode tests: compile requests, video recording, CLI installation detection, the skills and CLI workflows in settings and the setup wizard, the editor settings file, window screenshots, the Editor frame waiter, the migration wizard and its startup auto-scan, the Unity IPC server's accept loop, and the runInBackground override of CLI-started Play Mode. The production changes for these tests are test seams only; runtime behavior does not change.

User Impact

  • Before: after migrating a tool whose base class lost a PlayerLoopTiming parameter, calls from derived classes kept the old argument, so the project no longer compiled. A call on another object with a same-named method lost its argument, which broke code that compiled before the migration.
  • After: inherited calls are rewritten together with the declaration, including calls to methods that return arrays. Calls on other objects, and calls of a delegate local or lambda parameter named like the method, are left alone. When the migration cannot tell where a call goes, it leaves the call unchanged, so the compile error points at the call to edit by hand.
  • The test additions change nothing users see.

Changes

Known limitations

  • Inside a brace initializer such as new[] { Run(1, ..), Run(2, ..) }, the second and later calls are read as declarations, so inherited calls in that class are left unchanged, the same as before.
  • A nested deconstruction such as var ((Run, a), b) = .. is not recognized as declaring Run, so a call of that delegate is treated as an inherited call and loses its timing argument.
  • Names are collected per class: when a class also declares a local, parameter, or lambda parameter named like the method, its other unqualified calls of that name keep the timing argument, as before this change, and need a manual edit.

Release

  • fix: title, so release-please opens a Unity package release. No CLI source changes.

Verification

Closes #3126

…LI module now have tests for discovery and help rendering (#3074)
…ests for failure handling and release lookups (#3075)
…ve tests for routing, argument errors, and Unity failures (#3076)

The coverage work up to this point landed on main as one squashed commit. Recording main as a parent gives the integration branch a new merge base, so the next merge into main carries only the later changes instead of reapplying the squashed ones. The tree is unchanged.

📝 Walkthrough

Walkthrough

The PR adds hierarchy-aware caller rewriting for third-party timing migration. It also adds injectable dependencies and editor tests across CLI detection, setup workflows, compile and recording services, screenshot capture, and other editor utilities.

Changes

Inherited Timing Migration

Layer / File(s) Summary
Hierarchy index and source reader
Packages/src/Editor/Domain/ThirdPartyToolMigrationTypeHierarchy*.cs, Packages/src/Editor/Domain/ThirdPartyToolMigrationTimingTypeScopeRules.cs
New code reads class and record-class declarations, builds a type hierarchy index, and checks inherited-member reachability, including ambiguous and shadowed names.
Hierarchy-aware caller rewriting
Packages/src/Editor/Domain/ThirdPartyToolMigrationTiming*.cs, Packages/src/Editor/Infrastructure/ThirdPartyToolMigration/*
The cross-file planner builds and reuses the index, then passes it to caller-rewrite rules. The per-file migration pass supplies an empty index.
Migration tests
Assets/Tests/Editor/ThirdPartyToolMigration*Tests.cs
Tests cover inherited call forms, name resolution and hiding, and timing-parameter removal across derived callers.

Setup Wizard and Settings Workflows

Layer / File(s) Summary
Presentation adapters
Packages/src/Editor/Presentation/Shared/*, Assets/Tests/Editor/PresentationTestDoubles.cs
Dialog and background-work interfaces and implementations are added. Test doubles record calls and run work inline.
CLI install and PATH flows
Packages/src/Editor/Presentation/Setup/SetupWizardCliWorkflowController.cs, Packages/src/Editor/Presentation/UnityCliLoopSettingsCliSetupPresenter.cs, Assets/Tests/Editor/SetupWizardWorkflowControllersTests.cs, Assets/Tests/Editor/UnityCliLoopSettingsCliSetupPresenterFlowTests.cs
CLI setup components use injected dialogs for messages and PATH setup. Tests cover installation, PATH repair, uninstall, and failures.
Skills and startup flows
Packages/src/Editor/Presentation/Setup/SetupWizardSkillsWorkflowController.cs, Packages/src/Editor/Presentation/Setup/SetupWizardStartupFlow.cs, Packages/src/Editor/Presentation/UnityCliLoopSettingsSkillsPresenter.cs, Assets/Tests/Editor/SetupWizardStartupFlowVersionChangeTests.cs, Assets/Tests/Editor/SetupWizardWorkflowControllersTests.cs, Assets/Tests/Editor/UnityCliLoopSettingsSkillsPresenterStateTests.cs
Skills and startup components route background work through an injected runner. Tests cover scans, installs, cancellation, version changes, and auto-scan actions.
Migration wizard flow
Packages/src/Editor/Presentation/Setup/ThirdPartyToolMigrationWizardWorkflowController.cs, Assets/Tests/Editor/ThirdPartyToolMigrationWizardWorkflowControllerTests.cs
The migration wizard uses injected dialogs and background work for preview and apply. Tests cover scan, confirmation, cancellation, and apply outcomes.

CLI Detection and Environment Resolution

Layer / File(s) Summary
Detection and resolver seams
Packages/src/Editor/Infrastructure/CLI/CliInstallationDetector.cs, Packages/src/Editor/Infrastructure/Utils/NodeEnvironmentResolver.cs, Assets/Tests/Editor/CliInstallationDetector*Tests.cs, Assets/Tests/Editor/NodeEnvironmentResolverTests.cs
CLI detection accepts injected detection and command-runner delegates. Internal resolver methods support tests for command results, path selection, output parsing, and username validation.

Compile Pipeline

Layer / File(s) Summary
Compile port and controller wiring
Packages/src/Editor/FirstPartyTools/Compile/CompileController.cs, Packages/src/Editor/FirstPartyTools/Compile/CompilePipelinePort.cs
CompileController routes Unity compile operations through a port and rejects port replacement while a compile is active.
Compile lifecycle tests
Assets/Tests/Editor/CompileControllerPipelineTests.cs
Tests cover compile results, concurrent calls, errors, cleanup, cancellation, and attempted port replacement.

Recording Session Lifecycle

Layer / File(s) Summary
Session host
Packages/src/Editor/FirstPartyTools/RecordVideo/RecordVideoService.cs, Packages/src/Editor/FirstPartyTools/RecordVideo/RecordVideoSessionHost.cs
RecordVideoService delegates recording state and operations to RecordVideoSessionHost, which owns session updates, finalization, retention, and lifecycle callbacks.
Host and fixture tests
Assets/Tests/Editor/RecordVideoSessionHostTests.cs, Assets/Tests/Editor/RecordVideoUseCase*Tests.cs
Tests cover encoder selection, recording updates, stop and lifecycle behavior. Use-case fixtures now restore saved state only when setup successfully set it aside.

Editor Service Test Seams

Layer / File(s) Summary
Play Mode run-in-background access
Packages/src/Editor/FirstPartyTools/ControlPlayMode/CliPlayModeRunInBackgroundService.cs, Assets/Tests/Editor/CliPlayModeRunInBackgroundServiceTests.cs, Assets/Tests/Editor/ControlPlayModeUseCaseTests.cs
The service accepts getter and setter delegates for run-in-background state. Tests cover state restoration and use a recording starter in Play Mode use-case tests.
Frame waiter timeout
Packages/src/Editor/ToolContracts/EditorFrameWaiter.cs, Assets/Tests/Editor/EditorFrameWaiterServiceTests.cs
The frame waiter accepts an injected timeout. Tests cover frame completion, timeout, cancellation, and request cleanup.
Bridge server lifecycle
Packages/src/Editor/Infrastructure/UnityCliLoopBridgeServer.cs, Assets/Tests/Editor/UnityCliLoopBridgeServerLoopTests.cs
The server accepts injected listener and client-accept operations. Tests cover start, accept-loop exit, stop, and disposal.

Screenshot Window Capture

Layer / File(s) Summary
Capture service injection and tests
Packages/src/Editor/FirstPartyTools/Screenshot/ScreenshotUseCase.cs, Assets/Tests/Editor/ScreenshotUseCaseWindowCaptureTests.cs
ScreenshotUseCase routes window lookup and capture through an injected service. Tests cover fallback lookup, captures, timeouts, and save failures.

Settings Recovery and Async Test Guardrails

Layer / File(s) Summary
Settings recovery tests
Assets/Tests/Editor/UnityCliLoopEditorSettingsRecoveryTests.cs
Tests cover settings persistence, blank and oversized input, legacy-file handling, and nested legacy fields.
Async test cancellation checks
Assets/Tests/Editor/ScreenshotUseCaseTests.cs, Assets/Tests/Editor/UncanceledAwaits.cs, docs/unity-editmode-test-guardrails.md
Awaited validation tests and the shared helper fail explicitly on unexpected cancellation. The documentation states the same test rule.
Coverage baseline
coverage-baseline.json
The C# line coverage baseline changes from 85.4 to 87.3.

Merge Risk: 🔵 Low · up to d2d75

Inherited-call timing migration works in the common cases. Two uncommon code shapes can still produce code that does not compile after migration: a protected method with an array return type, and a lambda parameter that shares the method's name. Both fixes are small. The other changes add test seams and do not change runtime behavior.

Security Architecture Review

Security architecture risk: 🔵 Low · up to d2d75

The inspected changes retain existing access controls, command execution behavior, and recording limits. No new security issue was established, but incomplete coverage prevents a minimal-risk conclusion.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — The inspected IPC path retains the running Editor's existing tool-dispatch authority. Production construction uses the existing listener defaults, and accepted clients continue into the existing execution router; the seams do not establish an additional attacker-reachable dispatch path.

Trust Boundaries and Controls

  • observed — The default transport path retains Unix endpoint security policy application and Windows owner-only named-pipe security. Listener replacement requires in-process access to internal seams; production startup does not supply overrides.

Resilience and Maintainability Implications

  • observed — Recording extraction preserves one active session, maximum-duration enforcement, idempotent stopping, and centralized terminal cleanup. Reload and quitting retain their stop paths; snapshot persistence exceptions and default-directory retention remain unchanged. This limits continued capture and stale ownership as before, rather than adding a new privacy guarantee.

Explanation

For #3126, the type-hierarchy index and cross-file migration pass address unqualified, this., and base. calls, including intermediate base classes. The summary also reports conservative handling of ambiguous or unresolved types, shadowing, and calls on other objects, with migration tests. The available evidence does not establish whether a using static import that could supply the method name prevents rewriting, as #3126 requires.

Full details: Out of Scope Changes check

Explanation

The hierarchy-index implementation and migration tests support #3126. The PR also adds unrelated tests and test seams for compile requests, video recording, CLI detection and setup, screenshots, frame waiting, IPC, Play Mode, settings, and migration-wizard workflows. The settings coverage-baseline update and general async-test guardrail do not implement #3126.

Full details: Docstring Coverage

Explanation

Docstring coverage is 46.21% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Analyzed 541 functions across 50 files. (5 skipped: 2 unsupported, 3 over the file limit.)

- Around line 326-354: Update IsDeclarationName to recognize lambda parameters
as declarations when the next code token after the identifier is =>, including
identifiers inside parenthesized parameter lists when the closing ) is followed
by =>. Preserve the existing handling for other identifier contexts, and add an
index test verifying IsInheritedMemberReachable returns false for a
delegate-parameter call inside a lambda.
- Around line 201-220: Update ReadModifierText so its backward scan skips a
closing bracket when the matching bracket pair is an array rank specifier,
rather than treating it as an attribute boundary; retain the existing boundary
behavior for attributes. Add a ThirdPartyToolMigrationTypeHierarchyIndexTests
case where Runner declares a protected int[] Run method and verify
IsInheritedMemberReachable returns true.
