Poplog skill-2026.10 — Linux aarch64 and riscv64 join the fleet

The skill-2026.10 release of the Poplog runtime and the pop11 Claude skill is out, and the headline is platform coverage: the August release carried macOS arm64 and Linux x86_64; this one adds Linux aarch64 (Raspberry Pi 5 class) and Linux riscv64 — the two ports the revival project set out to deliver.

The bug worth telling

Every engine in this release is bootstrapped from a re-blessed corepop seed (corepops-2026.10), and the reason is a good story. The three non-x86 seeds each predated their platform’s struct STATB layout fix. That mattered more than it sounds: poplibr, the library tool, is a symlink to corepop, so the librarian stamped library members with dates read through the seed’s wrong struct offsets — a library built in the afternoon would list as 1996. On top of that, sys_file_stat was returning st_blksize where file_size should be and the mtime nanoseconds as file_mtime; the Z-machine test suite failed outright on both new boards and now passes 100/100.

The test harness got stricter too: a suite that prints a green summary and then dies no longer counts — the verdict is ALL PASS and engine exit 0.

Built and verified on its own hardware

Every tarball comes from a clean bootstrap on the platform’s own silicon: engine rebuilt from the seed, the self-test gate green, then the package unpacked into a sandbox $HOME, installed, and smoke-tested through both the MCP and LSP protocols. Downloads are all near 2 MB — the engine, pop/lib as source, the skill, both protocol servers, and the story files.

The release also carries edition 1.9 of Pop-11 and the Robot Army, with the cheat sheet now covering chapter 8’s examples.
