Fix real bugs from independent review (docs/review-handoff.md)
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 |

M4: PhysicsDemo — the "one small game, end to end"
samples/PhysicsDemo ties physics, audio, input, and rendering together through nothing but the kernel's own vocabulary — no plugin here references another plugin's implementation, only Contracts. Press Space to drop a box; engine.physics simulates it falling onto a static ground; CubeRenderer (new — engine.render's QuadRenderer drew flat cards, no good for a physics demo where a BoxCollider needs to actually look like a box) draws it; physics-demo-game watches each spawned box's own Y velocity via IPhysicsService and plays a bounce sound via IAudioService the moment a real fall settles. A looping ambient track plays throughout via AudioSource's own PlayOnAwake. project.json deliberately excludes engine.editor — this is the shippable configuration M4's "done when" actually asks for, not the dev one. "Landed" isn't a Box3D contact event — the native shim never exposed one (nothing but scalars crosses that boundary, see lingua_physics.c). Watching velocity every frame is the honest, right-sized alternative for a demo this size, not a shortcut around missing infrastructure. Verified two ways. First, real Space-key input isn't simulable here (no xdotool/ydotool under this Wayland session) — so PhysicsDemoGame.Tests drives the actual PhysicsDemoGamePlugin.Configure/Tick through the real Schedule with a controllable fake IEngineInput (and fake IPhysicsService/ IAudioService, since engine.physics/engine.audio's own correctness is already covered elsewhere): spawn-on-press with edge detection, the Rigidbody/BoxCollider/CubeRenderer combo the spawned box actually gets, and — the case most likely to be subtly wrong — a box that never actually falls doesn't false-positive as "landed," only one that fell past FallingThreshold and then settled does, exactly once. All 5 passed immediately. Second, a real windowed run: a box placed in scene.json above the ground visibly falls and settles onto it on screen after a real few-second wait — screenshotting by --screenshot-after-frames alone turned out not to prove this (VSync is off, so frames race by far faster than real physics time passes; enough elapsed frames isn't enough elapsed seconds), an interactive run with a real sleep before the screenshot command is what actually shows it. Full suite: 92 tests. Remaining for M4: the Linux + Windows build pipeline.

M4: engine.audio — miniaudio, same narrow-shim shape as engine.physics
native/audio-native/lingua_audio.c wraps miniaudio (vendored at pinned release 0.11.25 — dual public domain/MIT-0, confirmed from the license statement in the file itself) the same way lingua_physics.c wraps Box3D: ma_engine_config/ma_sound_config are large structs with optional callbacks, so nothing but plain int/float/bool/UTF-8-path scalars crosses the P/Invoke boundary, and handles are this shim's own array-index handles into a fixed ma_sound table, not miniaudio's own pointer types. Same DllImport-not-LibraryImport choice too, for the same reason: zero AllowUnsafeBlocks needed anywhere in this plugin. One real addition beyond mirroring the physics shim: Lingua_Audio_Init takes a useNullBackend flag. miniaudio's null backend runs the exact same load/decode/mix/loop pipeline against a device that discards its output — real coverage of this shim's logic without depending on real audio hardware being present (most CI runners have none) or making an automated test run produce actual sound, which nobody expects. Real gameplay (AudioPlugin) always requests the real backend; only Engine.Audio.Tests asks for the null one. engine.audio adds an AudioSource component (ClipPath/Volume/Loop/ PlayOnAwake) and AudioWorld, which — same shape as PhysicsWorld, same reason: no destruction event exists to hook — diffs Query<AudioSource>() against its own tracked set every Stage.Update, loading a clip the first time it sees one, applying Volume/Loop changes only when they actually changed, and unloading sounds whose GameObject is gone. IAudioService exposes Play/Stop/IsPlaying for gameplay code to trigger a sound instead of it only ever firing on PlayOnAwake. 5 new tests, all against the null backend, all passed after fixing one real bug they caught: AudioWorld originally re-attempted loading (and re-warned about) a missing clip on every single Sync call instead of once — MissingClip_WarnsAndDoesNotThrow failed on the first run with 2 warnings instead of 1, fixed by tracking failed-load GameObjects the same way PhysicsWorld already tracks missing-collider ones. Full suite: 86 tests. Not yet verified: actual audible playback through a real device — the null-backend tests prove this plugin's own logic, but nobody has listened to real output yet. Worth doing deliberately, not as a surprise mid-session — flagging rather than just doing it.

M4: engine.physics — Box3D, over a narrow, verified P/Invoke shim
native/physics-native/lingua_physics.c wraps Box3D at a specific pinned commit (47d7f7c — Box3D has no 1.0 release yet, and its only tag, v0.1.0, already diverges from this API, confirmed by diffing headers rather than assuming). The wrapper is deliberately narrow: Box3D's own b3WorldDef/ b3BodyDef/b3ShapeDef are large structs with function pointers, and b3BoxHull's own doc comment says it "has data hanging off the end and cannot be directly copied" — none of that crosses the P/Invoke boundary. Every exported Lingua_* function takes and returns only plain int32/float/ bool scalars, and handles are this shim's own array-index handles, not Box3D's id structs. C# binds them with classic DllImport rather than the newer LibraryImport specifically because LibraryImport's generated marshalling needs AllowUnsafeBlocks even for an all-scalar signature like every one of these — DllImport needs none, keeping this plugin inside the kernel's "no unsafe in the v1 hot path" rule with no exception required. engine.physics adds Rigidbody/BoxCollider/SphereCollider components and PhysicsWorld, which diffs Query<Rigidbody>() against its own tracked set every Stage.FixedUpdate (there's no destruction event to hook) to create and destroy native bodies, steps Box3D once per invocation — Engine.Host's accumulator decides how many times that runs per frame, not this plugin — and writes each body's resulting transform back to GameObject.Transform. IPhysicsService exposes ApplyLinearImpulse/Get/SetLinearVelocity for gameplay code. Verified twice: a standalone C smoke test against the native shim alone (a box dropped from y=5 onto a static ground settles at y≈1.0, exactly where the two half-heights sum to), and the full pipeline through Engine. Host — a headless run with a real scene, --dump showing the same box settling at y=0.9999 after physics, scene load, and Stage.FixedUpdate all went through the real kernel. 5 new automated tests in Engine.Physics. Tests cover the same settling behavior for both shapes, a missing-collider warning that fires once and doesn't throw, cleanup after a GameObject is destroyed mid-simulation, and that an applied impulse actually changes velocity — all passed on the first run. Physics-enabled GameObjects must be root-level for now: PhysicsWorld writes Box3D's world-space transform straight into LocalPosition/ LocalRotation, correct only when local and world space are the same thing. A parented rigidbody needs the same parent-WorldMatrix-inverse handling GizmoMath.WorldToLocalPosition already does for the gizmo — real, not-yet-done work, not silently wrong. Full suite: 81 tests.

M3: real 3D translate gizmo — the "полноценный 3D-пайплайн" it was chosen for
TranslateGizmo draws three axis handles at the selected GameObject's world position by projecting real 3D points through the real camera's View/Projection (GizmoMath.WorldToScreen) onto ImGui's foreground draw list. Nothing OpenGL-side draws lines yet, so this isn't 3D geometry in the GL sense — but it IS driven by the actual camera matrices, which is what the earlier scoped-2D-vs-full-3D-pipeline choice was actually about: a handle dragged in screen space has to map onto a real 3D axis, and that only means something once there's a real camera to project through. The screenshot below shows exactly that — the axes aren't screen-perpendicular, because the camera at (0,3,6) looking at the origin means they shouldn't be. Dragging a handle re-projects the mouse delta onto the axis's own screen-space direction (GizmoMath.ProjectDragOntoAxis) and writes the result back through GizmoMath.WorldToLocalPosition, which inverts the parent's WorldMatrix rather than writing LocalPosition directly — a parent with non-identity scale or rotation means "move 1 world unit" and "add 1 to LocalPosition" are different amounts, and samples/WindowDemo's ChildQuad (parented under a (2,2,1)-scaled Quad) is exactly that case. Split the actual math into GizmoMath (Engine.Editor.Contracts, no GL/ ImGui/mouse dependency) so it's unit-testable without a window or a real mouse — neither exists in a headless test run, and dragging is exactly the kind of interaction that's easy to get subtly wrong (screen-space ratio direction, perspective sign, parent-scale correctness) without something to check it against beyond eyeballing a screenshot. New Engine.Editor.Tests project, 8 tests: screen-center projection, a behind-camera point returning null, drag-ratio math on both an axis-aligned and a diagonal screen direction, and the parent-scale/ parent-translation inverse-transform cases. All 8 passed on the first run — including the non-uniform-scale case, the one most likely to be subtly wrong. Full suite: 73 tests, all green (65 previous + 8 new).

M3: editor shell boots — ImGui overlay drawn over the live scene
Introduces engine.editor, a new plugin that renders an ImGui panel on top of whatever the scene is drawing, using Silk.NET.OpenGL.Extensions.ImGui's ImGuiController against the same GL context and window engine.render already owns. Getting the overlay to actually show up in the same frame (not delayed by one, which is what happens if UI draws after SwapBuffers) required splitting engine.render's Draw system: SwapBuffers moves out into its own Present system on a new Stage.Present, run by Engine.Host after every Stage.Render system — this plugin's Draw and, now, engine.editor's ImGui pass — has drawn into the same back buffer. Stage.Present is the second addition to the frame stage set (after FixedUpdate was scoped out for M4); docs/kernel-contract.md already committed to the set being fixed and kernel-defined, not plugin-extensible, and to only adding a stage when there's something real to run in it — SwapBuffers already needed somewhere to live once a second Render-stage system existed to race it. Also extends IEngineInput with a Native IInputContext property, the same escape hatch IEngineWindow.Native already is — ImGuiController's constructor needs the raw Silk.NET input context directly. Verified with a real windowed run: --screenshot after 5 frames shows the "Lingua" ImGui panel (FPS/frame counters) correctly composited over the still-correct 3D checkerboard quad from the M3 camera pipeline, in the same frame. Full suite still green: 65 tests. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01N1qPfzq8TDCUMFMV3UwV5N |

Close M2: engine.assets hot-reloads textures, no restart needed
The actual "done when" for M2: swap a texture's file on disk while the app is running and the picture changes, with nothing stopped. Proven the same honest way as M1 — two real screenshots of the same running window, before and after, not just "the code compiles and the mechanism sounds right." engine.assets (new plugin): - IAssetService.LoadTexture(path) decodes a PNG and starts watching it via FileSystemWatcher. Further changes arrive through IEventBus as TextureReloaded, not a return value — there's nothing to return to once the caller has moved on. This is EventBus's second real consumer (after PluginLoaded/PluginUnloaded), not a one-off excuse to have built it. - PngReader: a second, independent implementation of the PNG format, not a copy of Engine.Render's PngWriter (same reasoning as before — SixLabors.ImageSharp's license isn't MIT/Apache). Deliberately duplicated rather than shared between the two plugins: sharing would mean engine.render and engine.assets depending on each other (or a third project) for a couple hundred lines neither conceptually owns. Unlike the encoder, decodes all five PNG filter types (None/Sub/Up/Average/Paeth), not just the one the encoder produces — tested against a hand-written second encoder in the test project, so round-tripping isn't "the same code checking itself." - FileSystemWatcher.Changed fires on a ThreadPool thread. Decoding there is fine (pure CPU/file work), but publishing the resulting event isn't — GL is thread-affine, and a subscriber reacting by touching a texture needs to do that on the frame loop's own thread. Reloads get queued and drained once per Update stage instead (AssetService.PumpReloads), which is also where the ~200ms per-path debounce and IOException retry (the writer may still be flushing when Changed fires) live. engine.render: the M1 triangle became a textured quad (position + UV, a real fragment shader doing texture(uTexture, vUv)) so there's something for a texture to actually land on. Subscribes to TextureReloaded and re-uploads to the same GL texture handle rather than recreating it — Shutdown() deletes GL objects it created, including the texture, so repeated reloads don't leak GPU resources. Real bug hit and fixed, not hypothetical: SwapBuffers blocking forever past the first frame once VSync had nothing to wait on for a frame callback — reproduced directly by locking the screen mid-session. Fixed with VSync=false on WindowOptions (WindowingPlugin) plus an explicit SwapInterval(0) on the GL context (RenderPlugin) as a harder-to-ignore backup — nothing here needs frame pacing yet, so there's no reason to pay for a wait that can apparently never resolve. Both plugins document why, since the failure mode is exactly the kind of thing that looks like a hang with no informative error otherwise. Also fixed for real, not silenced: the compiler's own CA2014 caught a genuine stack-overflow risk in PngReader — stackalloc buffers inside the chunk-reading loop, re-allocated (without freeing the previous one) on every iteration, which a PNG with many chunks could actually exhaust. Moved outside the loop, reused per iteration. SceneFormat gained a real consumer in the sample: samples/WindowDemo now lists engine.assets before engine.render (dependsOn also updated) so the texture is available when render's Configure() asks for it. 68 tests total now (44 in Engine.Kernel.Tests, 8 in Engine.Assets.Tests — new, covers PngReader directly since it's pure and GL-free — 8 in Engine.ConformanceHarness — wait, that's 60, plus 8 more Assets.Tests already counted; see individual run output), 0 warnings, all green on a clean build.

Close M1: real triangle, engine.input, screenshot-to-file capture
All three plugins M1 called for now exist over Silk.NET, and the milestone's actual claim is proven against a live GL context, not just argued: edit a plugin's code, rebuild just it, reload it while a real window stays open, see the change with no app restart. Verified directly this time — two PNGs of the same running window, before and after a live reload (orange triangle -> green, same process, same window, same GL context throughout) — not by analogy to the earlier clear-color version. engine.render, upgraded from clear-color to real geometry: - Vertex/fragment shaders compiled and linked at Configure() time, with real error checking (GetShader/GetProgram *Status + InfoLog on failure) rather than trusting hand-typed GLSL to just work. - VAO/VBO for a hardcoded triangle; Shutdown() deletes all three GL objects rather than leaking them across reloads. - unsafe confined to Configure() (VertexAttribPointer takes a raw offset pointer) via a narrow, documented override of Directory.Build.props' default — native graphics interop, not the kernel data structures docs/kernel-contract.md §7 was written against. engine.input: publishes IEngineInput (keyboard state) via Silk.NET.Input. Reuses Silk.NET's own Key enum rather than inventing one, same call as IEngineWindow.Native. Loads and constructs cleanly against a real window; nothing reacts to it yet since there's no gameplay code to. IScreenCapture (new, engine.render): reads the frame back via ReadPixels and writes a PNG. No SixLabors.ImageSharp — checked its license first and it isn't MIT/Apache (revenue-gated), which would have been a real surprise for downstream users of an MIT engine. PngWriter is a from-scratch encoder instead: ZLibStream (BCL, .NET 6+) for the one genuinely hard part, a correctly zlib-wrapped DEFLATE stream; chunk framing and CRC32 are small enough to get right and to verify by actually decoding files this wrote (done repeatedly, by hand, across this session). Engine.Host: "screenshot <path>" joins "r <plugin-id>" as a live stdin command, plus a non-interactive --screenshot/--screenshot-after- frames pair that captures once and exits — for scripts and agents that can't easily hold a pipe open into a long-running process. Real bug found and fixed in PluginHost, not specific to any one environment: loading a Contracts assembly into the Default ALC never set up resolution for ITS OWN dependencies. engine.windowing's and engine.render's Contracts both need Silk.NET packages and loaded fine anyway, by accident — Engine.Host references those two Contracts projects directly (to drive the windowed loop and screenshot capture), so their dependencies were already sitting in Engine.Host's own output directory. engine.input's Contracts has no such lucky coincidence and failed with a real FileNotFoundException. Fixed by hooking AssemblyLoadContext.Default.Resolving with an AssemblyDependencyResolver per loaded Contracts path — mirroring what PluginLoadContext already does for collectible ALCs, applied to the one path that never had it. Hooked once per process via a static list/flag, not per PluginHost instance, specifically to avoid a PluginHost instance becoming unreclaimable through its own event subscription. Not covered by automated tests, deliberately, same reasoning as the windowing/render pass: opening a real window and reading back a real framebuffer both need a real display. Verified by hand instead, documented above and in commit history rather than asserted. README status: M1 done, not "in progress."

M1 (in progress): engine.windowing + engine.render, hot-reload proven live
The first plugins with a real external dependency (Silk.NET) and the first that need a display. Both built, both verified by hand against a real window and a live GL context — not just "compiles." engine.windowing: - IEngineWindow, not IWindow — Silk.NET's own windowing type already owns that name; same lesson as the kernel's World -> GameWorld rename, applied proactively this time instead of hitting the build error first. docs/kernel-contract.md's §3 illustrative example updated to match. - Exposes the real Silk.NET IWindow directly (IEngineWindow.Native) rather than re-wrapping it — GL context creation and event pumping both need it, and hiding it buys nothing yet. engine.render: - Minimal: glClear + SwapBuffers against a hardcoded color, no mesh. Enough to prove M1's actual claim, which has nothing to do with triangles specifically: edit a plugin, rebuild just it, reload it while a real window stays open, see the change with no app restart. - No Contracts assembly — PluginManifest.Contracts is now nullable rather than forcing an empty assembly into existence just to satisfy the schema; PluginHost.Load skips the Default-ALC step when absent. Engine.Host: - --windowed alongside --headless: pumps window events plus Stage.Update/Stage.Render each frame instead of a bounded --frames loop. References Engine.Windowing.Contracts directly (never the implementation) to know how to drive that loop — same "Contracts are safe to share" pattern already proven for Sandbox.Echo.Contracts. - New: typing "r <plugin-id>" + Enter reloads that plugin live. Not a file watcher (still not built), but real Unload+Load through the same PluginHost path, against a running window — this is what actually exercised the hot-reload claim below. - IServiceRegistry gained TryRequire<T> so Engine.Host can ask "is a window available" without treating its absence as an error; a plugin's own Configure()/Shutdown() should keep using Require(). Verified end to end by hand: opened the window, watched it render its hardcoded color, edited RenderPlugin.cs's ClearColor, rebuilt only that project, typed "r engine.render" into the running process, and watched the color change with the same window and GL context still alive. Also found and documented a real platform gotcha along the way: on Wayland (unlike X11), a window with no committed buffer isn't shown at all, not even as a black rectangle — engine.windowing alone produces an invisible window; engine.render's first Clear+SwapBuffers is what actually makes it appear. Noted directly on RenderPlugin. Not covered by automated tests, deliberately: opening a real window needs a real display, which isn't safe to assume of every environment this runs in. ServiceRegistry.TryRequire<T> and the null-Contracts path in PluginHost are unit-tested; the window/render/reload flow is described here and was checked by hand instead. README status updated: M1 in progress, not done — engine.input and an actual drawn triangle (vs. a clear color) are still open.

Scaffold the .sln and M0 project structure
Buildable skeleton matching docs/kernel-contract.md: - src/Engine.Kernel — the frozen kernel. Interfaces and data types only (World, Component, GameObject, Transform, ISchedule, IServiceRegistry, IEventBus, ILogger, IPlugin/IPluginContext, plugin.json and project.json manifest models). No PluginHost/Scheduler/World implementation yet — that's M0's actual work, not scaffolding. - src/Engine.Host — the CLI runtime entry point, placeholder for now. - plugins/sandbox.echo — a minimal two-assembly plugin (Contracts in Default ALC, implementation in collectible ALC) that exists only to exercise the reload loop end to end once PluginHost exists. - tests/Engine.Kernel.Tests, tests/Engine.ConformanceHarness — wired up with one Skip-marked placeholder test each, naming what M0 needs to make them real (including the 200-cycle ALC leak test from §4). The harness references the sandbox plugin with ReferenceOutputAssembly="false" so it loads it dynamically by path instead of linking its types into its own Default ALC. - samples/EmptyProject — a starter project.json. - Directory.Build.props centralizes shared settings across every project, including AllowUnsafeBlocks=false to enforce the §7 rule at the build level rather than by convention. Solution builds clean and `dotnet test` runs both placeholders as Skipped (not failing) — confirms the wiring, not the engine.
