Per decision: displays need none of the fleet-wide common scope's software, so the gea-shopfloor-display scope carries everything it enforces and does not inherit common. This avoids repackaging common's SMB-backed payloads for a share-less display. - Invert the client common-merge switch: -NoCommon (default-on) becomes -IncludeCommon (default OFF). A scope now enforces alone unless opted in. The capability stays for a future share-less non-display PC; displays omit it. - Drop the common SMB-payload audit + inheritance sections from the display seed comments and docs (GE-ENFORCE-DISPLAY.md); document self-sufficiency. - GE-ENFORCE-CLIENT.md: common-scope inheritance is now opt-in.

# GE-Enforce: the gea-shopfloor-display scope
|
|
|
|
Displays are the share-less corner of the fleet. They are Intune/Entra-joined,
|
|
credential-less kiosk PCs that pull their manifest over HTTPS on port 443 and
|
|
authenticate with a read-only service PAT scoped `geenforce.fetch`, sent as
|
|
`X-API-Key`. They have no SMB share mount. The kiosk engine and the kiosk
|
|
browser are baked into the display image, not shipped over HTTPS, so the display
|
|
manifest heals POLICY / CONFIG drift only, never EXEs. It is self-sufficient and
|
|
does not inherit the fleet-wide `common` scope (see below).
|
|
|
|
There are three display subtypes, selected by `C:\Enrollment\display-type.txt`:
|
|
`Dashboard`, `Lobby`, and `3DPrintRoom`.
|
|
|
|
## Authoring the scope
|
|
|
|
The scope is authored programmatically by
|
|
`plugins/geenforce/seed_display_scope.py`, which builds a manifest dict and
|
|
hands it to `service.replace_scope_draft` (the same call the `import-share` CLI
|
|
uses), then attaches the inline dispatcher payload. From a Flask app context:
|
|
|
|
```python
|
|
from plugins.geenforce.seed_display_scope import seed_display_scope
|
|
seed_display_scope(publish=True) # publish=False leaves it as a draft
|
|
```
|
|
|
|
`replace_scope_draft` is an idempotent draft rebuild. `publish=True` additionally
|
|
freezes an immutable published snapshot (that step is not idempotent: it always
|
|
creates a new version).
|
|
|
|
### What the scope contains
|
|
|
|
1. Four `Registry` drift-heal entries that re-assert the Microsoft Edge kiosk
|
|
relaunch policies set at imaging by `09-Setup-Display.ps1`. Each writes the
|
|
value and detects drift with `DetectionMethod = ValueMatches` against the
|
|
same path/name, so a display that loses a policy self-heals on the next
|
|
enforce cycle with no keyboard or mouse on site:
|
|
- `RelaunchNotification = 2` (DWord, Required auto-restart)
|
|
- `RelaunchNotificationPeriod = 3600000` (DWord, 1 hour)
|
|
- `RelaunchHeadsUpPeriod = 60000` (DWord, 1 minute)
|
|
- `RelaunchWindow` (String, JSON, 02:00 start, 120 minute duration)
|
|
2. One `PS1` dispatcher, delivered inline over HTTPS. It reads
|
|
`C:\Enrollment\display-type.txt` and launches the kiosk target for the
|
|
subtype. The subtype -> route map is a data-driven table
|
|
(`DISPLAY_TYPE_TARGETS`) at the top of both the seed module and the generated
|
|
script, so targets are easy to edit. `DetectionMethod = Always` so it
|
|
re-asserts each cycle, but the script is idempotent (it skips relaunch if a
|
|
kiosk process is already serving the target URL).
|
|
|
|
### display-type -> target map
|
|
|
|
| display-type.txt | kiosk route | notes |
|
|
| --- | --- | --- |
|
|
| `Dashboard` | `/shopfloor` | core ShopfloorDashboard, standalone full-screen |
|
|
| `Lobby` | `/tv` | slides plugin TV dashboard (surface `lobby`) |
|
|
| `3DPrintRoom` | `/parts-kiosk` | **PLACEHOLDER, TODO-confirm** printedparts parts kiosk route; confirm the real 3D-print-room target with the floor team before publishing to production displays |
|
|
|
|
## Self-sufficient: displays do NOT inherit common
|
|
|
|
The `gea-shopfloor-display` scope carries everything a display enforces. It does
|
|
NOT inherit the fleet-wide `common` scope. Displays run the enforcer with
|
|
common-merge off (the client default; common-merge is opt-in via
|
|
`Invoke-ShopdbEnforce.ps1 -IncludeCommon`), so `common`'s SMB-backed fleet
|
|
entries (Adobe, Oracle, OpenText, Defect Tracker, EventSaver, printer map,
|
|
self-update, asset-reporting, ...) never reach a share-less display.
|
|
|
|
This was a deliberate decision: a display needs none of common's software, and
|
|
inheriting common would have forced repackaging every SMB `common` payload as
|
|
`http`/`inline` for a share-less box. Keeping the display scope self-sufficient
|
|
avoids all of that. If a future non-display share-less PC genuinely needs the
|
|
fleet-wide entries, that is what `-IncludeCommon` plus a per-entry SMB->http
|
|
payload conversion would be for -- but displays do not use it.
