Test bays reported 0 installed / 0 skipped / 0 failed and nothing was being processed. The share is a TRANSIENT mount: GE-Enforce.ps1 maps it for the length of its cycle and unmounts at the end - mounted 12:10:02, unmounted 12:10:27 on FB9TP7V3. The shadow task ran on its own 15-minute schedule, so it woke with the drive gone, handed the engine a path that no longer resolved, and the summary zero-filled. A silent nothing, indistinguishable from a healthy no-op, which is why it read as "not processing" rather than as a failure. Register-ShopdbShadow.ps1 is replaced by Invoke-ShopdbShadow.ps1, which runs AS a manifest entry and invokes the runner directly. The share is mounted because the enforce cycle is what called us; there is one cadence instead of two; and there is no task to register, drift, or heal. It also unregisters the superseded task, so bays that already carry it clean themselves up rather than keeping a run that cannot see the share and overwrites the real result with 0/0/0. The runner gains the Test-Path guard that should have been there: an unreachable -ShareManifestPath now logs, writes an event, and reports a real failure naming the reason, instead of running the engine against nothing. That silent zero is what made this expensive to find. Verified on the win11 VM with a substituted drive removed between runs - the same call gives real counts while mapped and the guard when not. The earlier task self-heal is moot now; it was a fix at the wrong layer, and testing against a local path is what hid a mount I had already noted was dynamic.

# Invoke-ShopdbShadow.ps1 -- run one shopdb SHADOW cycle, from the manifest.
|
|
#
|
|
# Shadow = fetch the shopdb manifest, diff it against the share manifest, report
|
|
# the cycle to shopdb. The engine still installs FROM THE SHARE, so behaviour is
|
|
# unchanged. It is the observable step before any cutover.
|
|
#
|
|
# WHY THIS RUNS AS A MANIFEST ENTRY AND NOT A SCHEDULED TASK
|
|
#
|
|
# The first version registered a separate 15-minute task. That cannot work:
|
|
# GE-Enforce.ps1 mounts the SFLD share for the length of its own cycle and
|
|
# unmounts it at the end (mounted 12:10:02, unmounted 12:10:27). A task on its
|
|
# own schedule therefore wakes up with the drive gone, hands the engine a path
|
|
# that no longer resolves, and reports 0 installed / 0 skipped / 0 failed - a
|
|
# silent nothing indistinguishable from a healthy no-op. It also meant two
|
|
# cadences that could drift apart, and a registration that had to be healed.
|
|
#
|
|
# Running here removes all of it: the share is mounted because the enforce cycle
|
|
# is what invoked us, the cadence is the fleet's own, and there is no task.
|
|
#
|
|
# Runs as SYSTEM under GE-Enforce, from an entry gated to the test bays.
|
|
# Fail-safe: exits 0 on every path - shadowing must never stop a bay enforcing.
