v0.7.0

Receipt

• Boxed ledger (window of 10 commits, benchmarks/compat2/boxed_cost.py): code share 5.0%, churn 7.7%, bug share 20% (1 of 5), iteration tax 10%, drop flag false. Earlier windows had bug shares of 75% and 100% on tiny samples, so the trend is watched, not yet a trigger.
• Dogfood: 8 of 8 corpus scripts and 8 of 8 libraries run at least on the island floor.
• Django assessment: 84.4% of definitions run on the island, 55.2% natively.
• Release rehearsal: build matrix, smoke and wheel verify passed on the base commit 954d6943.

Target	Artifact	Runner	Smoke
macos-arm64	pyscriptc-macos-arm64	macos-14	full
macos-x86_64	pyscriptc-macos-x86_64	macos-15-intel	full
linux-x86_64	pyscriptc-linux-x86_64	ubuntu-24.04	full
linux-aarch64	pyscriptc-linux-aarch64	ubuntu-24.04-arm	full
windows-x86_64 (experimental)	pyscriptc-windows-x86_64.exe	windows-2022	explain and --help only (see note)

Checksums for the five binaries are in sha256sums.txt.

Linux x86_64 and linux aarch64 are built on ubuntu-24.04. glibc on that image is 2.39. That is the floor for these artifacts. This workflow does not retarget an older runner to chase an older glibc.

pyscriptc-windows-x86_64.exe is experimental. The compiler binary may build with Nuitka MinGW64. Windows smoke covers explain and --help only, not compile and run: link_binary compiles every runtime/*.c into every emitted program, and ps_mix.c needs dlfcn.h/dlopen, which MinGW-w64 does not provide (programs also use dirent.h and unistd.h). There is no Windows arm64 artifact.

Each binary is the compiler only. User programs still need clang on PATH (see packaging/TOOLCHAIN.md). Nuitka does not cross-compile: each row is built on its own OS and CPU.
