heap-profile runs scripts\train-heap.ps1 on windows-2025 with the latest release's runtime (when its signed RUNTIME_STAMP is this commit's), uploads profiles/pi-X.Y.Z as an artifact and pushes it to heap-profile/pi-X.Y.Z.

heap-profile, a manual workflow that runsscripts\train-heap.ps1on GitHub's windows-2025 runner, so a new Pi version's Windows heap order no longer needs a local Windows machine.runtime(ubuntu): reads the Pi version, checksprofiles/pi-X.Y.Z/bytecode.orderexists, and requiresscripts/runtime-stamp.shto equal the latest release'sRUNTIME_STAMP, taken from its signedSHA256SUMS.train(windows-2025): the setup of release.yml's Windows job (AVX2 check,pyshim, the release's runtime checked against its signed checksums,npm ci,npm run build:offline), thenscripts\train-heap.ps1; uploadsprofiles/pi-X.Y.Zas an artifact.branch(ubuntu,contents: write): commits the artifact and pushesheap-profile/pi-X.Y.Z. The pull request is opened by hand, since one opened with the workflow's token would not runci.docs/RELEASING.md step 2 of "A new Pi version" mentions it.
