Profile 010069C01AB82000 (Atlus, Unreal Engine 4.27, SDK 15.3.2, NVN). Opening gameplay tested on the Mac: new game, classroom, saves and reload in a fresh process, Tokyo map, Shinagawa Station and its event. iOS and combat untested. - Memory: the FMallocBinned3 constructor cut (main+0x1f2f63c, gate +0x1f2f644) with the measured UE4 vtable in hle_uemalloc.c; -SwitchVirtualAddressSpaceSize=2048 and a 3.75 GB block. profile_guess.py now leaves 128 MB for the initial heap in provisional Unreal layouts (test_profile_guess.py). - Shaders (general, chain 86c8282f6fb4): returning IGN image atomics keep the old value with bounded access (Ryujinx translator, t_atomic_return.m); buffer-image reflection keeps its Metal texture type (nvn_refl.m, t_refl.m). All 19,746 shaders build for Mac and iOS. - 60 fps: hle_fpslock.c writes the game's own Project.FrameRateLimit (main+0x6d6d5d0, which GameUserSettings applies to t.MaxFPS) and rhi.SyncInterval, gated on main 0a4f14a5... Mac (M4 Pro): 59.2-60.1 fps at the station, frame p95 17.5-20.3 ms; a 1 s walk ends at the same place at 30 and 60 fps. DM_FPS_TARGET=30 keeps 30. Docs: the game note, games table, README gallery, memory.md, shaders.md, symptom index; AGENTS count 68 -> 69. Checked: tool tests (186, 6 skips), docs tests.
