Opening /r/berty/social with current Gno fails during package loading: the realm imports the unversioned txlink package and expects two return values from B+ tree Get, which now returns a single value.

Use gno.land/p/moul/txlink/v0 and check for nil in all five affected lookups. Add regression tests for missing and stored users, threads, replies, and reactions, including duplicate reactions and removal. Update the realm CI Gno pin to the validated checkout and its required Go version. A separate realm-unit-tests job runs the Gno unit tests on pull requests and pushes to main, resolving dependencies from the pinned examples workspace alongside the existing integration job.

Refresh every action used by the unit, integration, mobile-check, and release workflows to its latest release: checkout v7.0.1, setup-go v7.0.0, cache v6.1.0, asdf setup v4.0.1, Expo 9.0.1, and semantic-release v8.1.4.

Validation against Gno 14fe3eb356c52dd325c9cc10fc77d248b3b88f32:

• Both new regression tests passed using the CI workspace layout.
• All workflow YAML parsed successfully, and configured inputs were checked against the updated action manifests.
• The existing realm/tests/test.sh integration suite passed against an isolated gnodev.
• /r/berty/social returned HTTP 200 and rendered “Welcome to dSocial!”.

The package loads for me in my local gnodev.
