I think the aerial view may have caused some confusion about the layout, so I am adding an annotated aerial image to clarify it.
The bollards and barriers separate the school property from the public space in front of it.
This public space itself consists of two clearly distinguishable parts:
– a red-surfaced vehicle access lane, used for service vehicles, deliveries and emergency access. Vehicle access to this lane is controlled by road barriers at both ends;
– a wide light-grey paved pedestrian area, running alongside the vehicle lane and directly accessible from Rue de Paris.

The Little Free Library is located on this public pedestrian area, on the public side of the bollards and barriers separating it from the school property. No school gate or entrance needs to be crossed to reach it.
I have marked the vehicle-access barriers in red and the public pedestrian area in green on the attached aerial image. The recent ground-level photographs I provided above show the same layout and make the separation between the school property and the public space particularly clear.
The Little Free Library was installed by the municipality only a few weeks ago, which explains why it does not yet appear on Street View.
I have also found this map published on the official website of the City of Joinville-le-Pont https://www.joinville-le-pont.fr/vie-municipale/territoire/plan-de-la-ville/ I understand that the underlying cartographic data appears to come from OpenStreetMap, so I am not presenting it as an official cadastral or property-boundary document. However, I think it is useful because the boundary shown on the City’s map corresponds very closely to the physical separation visible on the current photographs.
The bollards and railings separate the school area from the area open to the general public. On the street side of that separation, the public space consists of two distinct parts: a red-surfaced lane used for vehicle access (including service, delivery or emergency access), and a paved pedestrian area between that lane and the school boundary. The Little Free Library is installed in this paved pedestrian area, on the public-facing side of the bollards/railings, and can be accessed directly from Rue de Paris without entering the school area.
I have also checked the French cadastral map following the comments above. The cadastral parcel does appear to extend over this area, so I withdraw my earlier assertion that the Wayspot is necessarily outside the school’s cadastral property. However, the cadastral parcel alone does not seem to resolve the question of the actual status and use of this particular strip of land.
In practice, this area has been laid out by the municipality as an open pedestrian space, permanently accessible from the street. https://drive.google.com/file/d/151bc4iNlN4waQAd506JBNj4i6Offd-Er/view?usp=drivesdk
The Little Free Library itself was recently installed there by the municipality for public use, which is why it does not yet appear on Street View. The adjacent school is a preschool/kindergarten, and the library is clearly positioned and intended as a public street amenity rather than as an amenity specifically for the pupils.
So I would appreciate clarification from the Wayfarer team on the relevant criterion here: is the K-12 exclusion determined solely by the cadastral parcel/property boundary, or can the actual legal/public use and physical configuration of the location also be taken into account where an amenity is installed in an openly accessible pedestrian area, physically separated from the school itself?
If the precise legal status of this strip of land is decisive, I can also contact the City of Joinville-le-Pont and ask them for an official document or written confirmation establishing the boundary between the school property and the public pedestrian/road space at this location.
