"_install":"Use the update-engine skill in the GAME repo (tinqs/ariki-game .agents/skills/update-engine) \u2014 everyone has ariki-game; nobody but Ozan has the engine source. It tinqs-pulls ariki-game + builds, installs the binary AND GodotSharp together into ../engine/bin, and clears stale caches.

"note":"Mac. Engine e64890fd = 4fde0e94 + Apple render-thread fix: the separate render thread (thread_model=2, the game default) now drains an Objective-C autorelease pool each flush - before, autoreleased Metal command buffers/encoders/drawables leaked ~88 Mach ports/s until Metal could not start new processes (66k ports / 23 GB after 1.5 h); now flat at ~640. Also RENDERING_INFO_GPU_CULL_MERGEABLE_DRAWS_IN_FRAME (G4 census) and draw_indirect_count null scratch now errors loudly. GodotSharp regenerated (with Tools/). Oracles on Metal: multimesh_cull_pool 4524/4524, draw_indirect_count 24/24. Windows at 4fde0e94; Forge to rebuild e64890fd (handoff forge-windows-e64890fd.md) - the leak fix is Apple-only, Windows gains only the counter."
"note":"Windows carries e64890fd3 — SAME hash as macos-arm64 (built at e64890fd3b): 4fde0e94 G2 pooled cull pair (see its note in git history) PLUS e64890fd3b — Apple-only render-thread autorelease drain (no Windows effect), RENDERING_INFO_GPU_CULL_MERGEABLE_DRAWS_IN_FRAME (new enum value 13, G4 census — env gpucull status shows '(N mergeable)'), Metal draw_indirect_count null scratch errors loudly (no Windows effect). GodotSharp regenerated from this binary — Api AND Tools. Headless game boot clean (0 binding errors); in-world smoke (host world, 0 wrapper errors, gpucull mergeable counter) per handoff still owed. Owed on Windows (carried): multimesh_cull_pool oracle on D3D12, --gpu-validation pass (Graphics Tools not installed on Forge), in-world gpucull census + pooled on/off, tree_wind compile check, crash-report checklist (8 steps). Editor target only — template_release still 1e7be28b. D3D12 Agility DLLs not shipped (Vulkan game)."
