Master's windows-python-console-spawn-wait fix removed the plugin-add flake
this branch previously retried, so that retry is dropped entirely; the
branch keeps the changes that remain useful.
- Retry the immutable install step up to three attempts total with a
ten-second pause (bash on every platform): node-gyp's Node-header
download from nodejs.org intermittently times out, as observed on the
hosted node24-macos-x64 cell.
- Keep checkout credentials out of the build tree (persist-credentials:
false) so dependency-install scripts cannot read the embedded token.
- Failover runbook: drop the stray leading '#' before the Dependabot
paragraph on both sides.
- Hosted-runtime note: name the PR/commit ownership and UTC timestamps of
the cited runs and record the constraints a future self-hosted attempt
must satisfy; new note records the install retry decision.
The failover runbook's Windows switch scope returns to the native Windows jobs:
remove the Python runtime eligibility sentences, the pool Python prerequisite,
and the proposal links. The #3629 self-hosted Python runtime proposal is
retired (deleted as obsolete after its unmeasured-throughput run), and a new
implemented note records that the Windows x64 runtime lane stays on
GitHub-hosted Windows with the evidence and alternatives. Bilingual sidecars
re-recorded.
The failover runbook's Windows switch scope returns to the native Windows jobs:
remove the Python runtime eligibility sentences, the pool Python prerequisite,
and the links to the proposal. The self-hosted Python runtime proposal is
moved to rejected with its unmeasured-throughput verdict, and a new
implemented note records that the Windows x64 runtime lane stays on
GitHub-hosted Windows with the reasons. Bilingual sidecars re-recorded.
Windows x64 runtime builds resolve their hosted matrix.runner unconditionally
again (windows-2025 for pull-request CI). Remove the DSH_CI_FAILOVER_WINDOWS
selector, job-private Python toolchain, self-hosted dependency install and
post-step cleanup, the private setup script, and the routing spec introduced
in #3629. The Windows failover switch again covers only the native Windows
jobs in ci.yml.
