seedds f4f0a85d6e patch_nso.py split into the general rewriter and per-build patch files (GitHub issue #63 ): every game's bring-up edited the one file, so PRs for unrelated games conflicted. dm/tools/patch_nso.py (1,711 → about 1,100 lines) keeps the general passes and the driver; the instruction encoders move unchanged to dm/tools/nso_asm.py; a game's own patches (CUTS, OBS and the frame-step stubs, now FRAME_STEP = {build ID: stub(ctx)}) move verbatim with their comments to dm/games/<id>/patches.py (16 profiles: Tears of the Kingdom, Breath of the Wild, Age of Calamity and Paper Mario: The Thousand-Year Door with their stubs), and the cuts of Nintendo's sdk module builds, 6 of the 15 shipped by 2 to 4 games, to dm/tools/sdk_patches.py. The rewriter loads every patch file, whatever the game, and applies those of a module's build ID at the points it did before (cuts before the scan, gates after the rewrite, stubs after the gates); a build ID claimed twice stops it, and its command line needs no DM_GAME. build_src.sha256 lists the rewriter's files and every patch file (the same for every module). NSP script: the rewrite step's reuse key counts nso_asm.py and only the patch files that name one of the game's builds (patch_files), profile_files leaves patches.py out (only the rewrite step reads it), and a derived profile gets none. dm/tools/tests/test_patches.py: no build claimed twice, the entries' forms, a game's file names only its own profile's non-sdk builds, sdk_patches.py only sdk builds some profile ships, and the reuse key's patch files. Checked byte-identical: every extracted module on the game drive (131 builds) rewritten with the previous and the new rewriter gives the same outputs but build_src.sha256, 28 of the 30 patched builds among them (all four frame-step mains), and 7 fail alike (rtld, and New Super Mario Bros. U Deluxe's, which no profile rewrites); the other two (Super Mario Bros. Wonder's mains and Absolum's, no game files here) by their CUTS / OBS data, equal to the previous tables. AGENTS.md, docs, dm/games/README.md, the profiles' comments and the host comments that named a game's cut in patch_nso.py now name its patches.py or sdk_patches.py

1	# The Legend of Zelda: Tears of the Kingdom (Switch, base game v0 + update 1.4.3 = v720896). In bring-up
2	# Nintendo EPD's engine (sead / agl / gsys, NintendoWare G3d2 / Ui2d / Vfx2, Havok), SDK 20.5.22, NVN; modules main + subsdk0 (NintendoSDK_movie) + sdk.

23	# The NPDM declares 24 MB of system resource, so IsVirtualAddressMemoryEnabled is true and the game's memory lives in the alias region (as Engage's, see 0100A6301214E000/game.tsv).
24	# The game also calls SetHeapSize(0x86000000) in nninitStartup (2.1 GB of the pool as its heap; a 2 GB heap region aborts there with 0xd401).
25	# What it can map is bounded by the pool less the heap (1.1 GB). The sdk build's node area is cut from ~1 GB to 62 MB (dm/tools/sdk_patches.py): measured on the Mac, the alias region is then used
26	# up to +1.75 GB on the Great Sky Island with 1.0 GB mapped. Without the cut it reached +2.25 GB at the first descent and the game took a memory shortage (MSF, a Blood Moon that puts Link back, issue #70).
27	# So 5 GB, the total proven on a phone (one reservation of at most 6 GB without the extended virtual addressing entitlement): 256 MB in front + 2.375 GB alias region + 256 MB stack region + 2.125 GB heap region
