Production SignPath signing requests require manual approval in the
SignPath UI, so the previous single-job flow (submit with
wait-for-completion inside a 40-minute window) let approval latency fail
the Windows build, and any re-run rebuilt the binaries and submitted a
second request needing a second approval.
The Windows lane is now two jobs: sign-windows-agent builds the unsigned
executables, submits the SignPath request without waiting, and uploads a
7-day signing-request record; collect-windows-signing absorbs approval
latency by polling the recorded request, downloads the signed artifact
by request id, and keeps the existing verification and evidence steps.
If approval outlasts the 115-minute polling window, the collection job
fails with re-run guidance and "Re-run failed jobs" collects the same
recorded request - no rebuild, no resubmission. The legacy PFX
break-glass backend rides the same two-job shape via an artifact
hand-off. Workflow output wiring, artifact names, and evidence content
are unchanged for downstream consumers.
The shape test now pins the async invariants (no wait-for-completion:
true in the candidate workflow), and the code signing policy plus the
deployment-installability contract describe the two-phase flow.
