"""Author the gea-shopfloor-display runtime scope programmatically.
Displays are Intune/Entra-joined, credential-less kiosk PCs that pull their
manifest over HTTPS (no SMB share). The kiosk engine and the kiosk browser are
BAKED INTO THE DISPLAY IMAGE, so this scope does not ship any EXE payloads; it
heals POLICY / CONFIG drift only, plus one dispatcher that points the kiosk at
the right target for the display subtype.
What this scope contains:
- Four Registry drift-heal entries that re-assert the Microsoft Edge kiosk
relaunch policies from the imaging script 09-Setup-Display.ps1 (so a display
that loses those policies self-heals on the next enforce cycle without a
keyboard or mouse on site).
- One inline PS1 dispatcher that reads C:\\Enrollment\\display-type.txt and
launches the kiosk target for the subtype. The display-type -> target map is
a data-driven table (DISPLAY_TYPE_TARGETS) so the targets are easy to edit.
Self-sufficient: the display scope carries EVERYTHING a display enforces and
does NOT inherit the fleet-wide 'common' scope. Displays run the enforcer with
common-merge off (the client default), so common's SMB-backed fleet entries
never reach a share-less display. This keeps the display path simple and needs
no common-payload repackaging.
Authoring path mirrors how every other scope is created: build a manifest dict
and hand it to service.replace_scope_draft (the same call the import-share CLI
uses), then attach the inline dispatcher payload and optionally publish. Re-
running replace_scope_draft is an idempotent draft rebuild.
