+# Changelog
+
+Assets served at `https://healthdatasafe.github.io/assets-demo/` (GitHub Pages from `main`),
+referenced by `demo.datasafe.dev` service-info → `assets.definitions`. The `version` field in
+`apps/list.json` is the cache-buster consumers key on.
+
+## 2026-05-29.2
+
+- `apps/list.json` bridge-mira `lastSync` descriptor: added **`faultyField: "faulty"`** so
+  hds-webapp can surface a "bridge unavailable/faulty" state when the bridge reports its
+  upstream integration as faulty (plan 66).
+
+## 2026-05-29.1
+
+- `apps/list.json` bridge-mira: added **`needsReauthField: "needsReauth"`** to the `lastSync`
+  descriptor; fixed the `resync.initiate` hook to send `body.returnUrl` + `openUrlField` so the
+  reconnect flow reaches `/mira/resync`. Bumped `version` (plan 66).
