Atrium 0.87.2 — The 0.87.1 fixes, as images

Packaging release. The container images of 0.87.1 were not published: the release was cut
while the live-bench run that attests the gateway-reading code for OpenClaw 2026.9.6 was
still finishing, so the tagged commit carried the attestation of the previous build and the
image pipeline refused it. 0.87.2 carries the fresh attestation and publishes the images.
It contains exactly the changes described under 0.87.1 — nothing else.

Upgrading. If you run the npm packages, 0.87.1 and 0.87.2 are the same. If you run the
container images, go straight from 0.87.0 to 0.87.2, and follow the 0.87.1 deployment note
(npx convex deploy together with the new bridge).
