# 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 and inherited common entries, never EXEs.

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 |

## Inheritance: the client merges common

The manifest model has no inheritance column. The display scope is a plain
(non-common) runtime scope carrying only display-specific entries. The CLIENT
merges the fleet-wide `common` scope underneath the display scope at fetch time.
So `common` is where the fleet-wide policy/config/self-update entries live, and
`gea-shopfloor-display` adds the kiosk-only entries on top.

## Blocker: common carries SMB payloads that break on share-less displays

Before a share-less display can safely inherit `common`, every `common` entry
that pulls a payload file from the SMB share must first be given an `http` or
`inline` payload (with a `payloadsha256`). A display has no share mount, so any
inherited entry whose `Installer` / `Source` / `Script` resolves to a
share-relative path will fail its fetch.

Registry entries in `common` carry no payload (they write inline reg values) and
are safe to inherit as-is. The entries below reference a share file and must be
converted first. This audit is the authoritative to-convert list; the payload
bytes themselves are not converted here (that needs the real payload files).

Common entries that reference an SMB/share payload (as of the on-share
`common/manifest.json`, 22 entries, Version 2.0):

Safe to inherit as-is (Registry entries, no share payload): `3OF9 barcode font
registry entry`, `Edge IE-Mode policy level`, `Edge IE-Mode policy site list
pointer`.

Not every entry above is relevant to a display (a display needs no Oracle
client, OpenText, or Defect Tracker), so a follow-up decision is which common
entries a display should actually run (via `PCTypes` targeting) versus which
must be repackaged as `http`/`inline`. But any that survive targeting must have
a non-SMB payload before displays inherit common.
