A second AI session read the whole codebase in parallel (read-only, no code changes) and left a handoff doc. Addressed the correctness findings: - PhysicsWorld.Sync's early return compared _bodies.Count to live.Count, not their contents — same size, different membership (destroy one tracked GameObject, gain one untracked-because-no-collider one; or any Restore where the scene has both a Rigidbody+collider object and a Rigidbody-without-one) skipped cleanup entirely, leaking the native Box3D body forever. Fixed by checking the actual stale set. Two new regression tests reproduce the review's own two scenarios via a new Lingua_GetBodyCount native export, asserting on the native table's own count rather than PhysicsWorld's C#-side bookkeeping. - TryCreateBody stored handle -1 (native shim refused: invalid world, or its 8192-slot body table full) as if it were real — every later GetBodyTransform on it silently teleported the GameObject to the origin with a degenerate rotation, no error anywhere. Now checked and warned once, same as the missing-collider case. - PluginHost.Load didn't roll back anything when Configure threw partway through: Schedule.Add/Events.Subscribe registrations it already made stayed forever, and its ALC was never unloaded — neither loaded (no _loaded entry) nor cleanly unloadable. Fixed with try/catch: best-effort Shutdown (the only thing that knows which services this plugin provided), RemoveAllFrom on both Schedule and EventBus, best-effort ALC unload, rethrow. New fixture plugin (sandbox.failing-configure, mirrors sandbox.echo's own real-load pattern) registers a system against a shared Ping component then throws, so FailedConfigureRollbackTests can assert the dangling system actually stops firing — an earlier version tried to prove this via AssemblyLoadContext.All instead, which passed even against the deliberately-reverted buggy code (the ALC turned out to get collected either way once its only references went out of scope); watching the dangling system is what actually distinguishes rolled-back from not, confirmed by deliberately reverting the fix and watching this specific test fail before restoring it. - Engine.Host's "r <id>" left a plugin unloaded on a failed reload with no honest indication of that, and retrying threw "not loaded" instead of ever reaching Load again. Added PluginHost.IsLoaded so the handler only calls Unload when there's something to unload, and the failure message now says the plugin is unloaded, not just "failed." - AssetService.ReloadWithRetry's `when (attempt < 4)` guard meant the 5th and final IOException fell out of the loop and propagated from a discarded fire-and-forget Task — no log, no event, nothing. Now logged. - EditorState.Selected kept pointing at a GameObject Restore had already destroyed after ExitPlay, so Inspector/gizmo would silently keep editing something no longer in the world. EditorPlugin.DrawUi now compares IsPlaying against its own previous frame (not just reacting to the Stop button) so this is caught whether Play was exited via the button or the "stop" stdin command — the same stdin-vs-real-control gap already hit once earlier this session — and re-resolves the selection by name. - README.md and kernel-contract.md's Event Bus/Time rows had fallen a milestone behind (still said "no asset system yet" and "no fixed-step accumulator yet" after both shipped). Full suite: 98 tests. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N1qPfzq8TDCUMFMV3UwV5N
