 2. **`getList` fetches the whole container on every call.** Filtering, sorting and pagination run in memory afterwards, so the cost of listing an event's participations grows with the user's total number of participations rather than with the event. No workaround; it is why a filter on a `getList` buys nothing beyond convenience.
 3. **A list subscription reports membership only.** A container channel delivers `Add`/`Remove`, not a member's own fields changing, so a list of events does not refresh when an event's title, place or time is edited. Watching each record instead would open one channel per row. The event list is exactly the screen where this is visible.
 4. **`types` takes precedence over `shapeTreeUri`, the opposite of what the configuration type documents.** The declared behaviour is that `types` is "only used as a fallback when `shapeTreeUri` is not set"; a resource setting both is in fact resolved from `types`. Establishing which one actually wins cost a read of the resolution path. Configuring exactly one avoids it, but the documentation should say which wins.
+5. **The member shape of an `apods:attendees` collection is not pinned anywhere Festipod may read at work time.** The reconstruction documents the container discovery, not what a membership record is: a bare actor URI, or an object carrying event/participant/status. The project reconnaissance records only that a join "adds the actor to the collection" and that members come back "as full objects for a reader who is allowed, and as URIs otherwise". The ActivityPods backend's participation binding is designed against that: a member maps to `{ id, userId, isConfirmed: true }` (membership IS the attendance), with `eventId` supplied by the reader — the event the collection was read from — because a member carries no event link. The first runtime read against the local platform (T04.g) must confirm or correct this mapping.
