The classifier missed modules the update entry points import
(_subprocess_compat, desktop_build_lock, memory_provider_migration, the
scripts/build compilers) and never sent source_build/source_completion to
the Desktop update suite. ci.yaml gated tests-os on `python` alone, so a
TypeScript-only change to the Electron marker/result readers set
desktop_updater and still never reached the Windows hand-off tests.
- classify_changes.py: _UPDATE_ENTRY_POINTS / _DESKTOP_BUILD_ENTRY_POINTS,
an owner list of what they import, and an explicit _SHARED_HUBS set.
- tests/ci/test_update_ci_routing.py reads the entry points' real imports
(AST incl. lazy imports; ESM import/step() closure of the build scripts)
and fails until each is routed or is a real hub (>= 25 importers).
- It also replays the REAL classifier's output through the composite
action, ci.yaml detect outputs, job if:/with:, the called workflows' job
if: and the rendered Windows step, for every combination of the gated
lanes (tests/ci/_gha_expr.py models the expression subset and raises on
anything else).
- ci.yaml: tests runs for python|e2e|e2e_upgrade; tests-os for
python|desktop_updater|e2e|e2e_upgrade.
Red on 8cc78279a36: 30 of the new routing tests fail (R15 table cells,
16 lane combinations, ownership/closure tests).
