 - Plugins/update: move ClawHub-preferred externalized plugin installs back to ClawHub after an earlier npm fallback once the ClawHub package becomes available. Thanks @vincentkoc.
 - Plugins/update: clean stale bundled load paths for already-externalized pinned npm and ClawHub plugin installs, so release-channel sync does not leave removed bundled paths ahead of the installed external package. Thanks @vincentkoc.
 - Plugins/update: repair stale managed npm-root `openclaw` peer packages before plugin installs, so beta-channel official plugin updates are not downgraded by old core package-lock state. Thanks @vincentkoc.
+- Plugins/install: run managed npm-root install, rollback, repair, and uninstall mutations with legacy peer resolution so removing one plugin cannot rehydrate a stale registry `openclaw` package into the shared root. Thanks @vincentkoc.
 - Plugins/install: reassert managed npm plugin `openclaw` peer links after shared-root npm installs, updates, and uninstalls, so mutating one plugin does not leave previously installed SDK-using plugins unable to resolve `openclaw/plugin-sdk/*`.
 - Plugins/update: make package upgrades swap pnpm/npm-prefix installs cleanly, keep legacy plugin install runtime chunks working, and on the beta channel fall back default-line npm plugins to default/latest when plugin beta releases are missing or fail install validation. Thanks @vincentkoc and @joshavant.
 - Plugins/active-memory: skip session-store channel entries that contain `:` when resolving the recall subagent's channel, so QQ c2c agent IDs (e.g. `c2c:10D4F7C2…`) and other scoped conversation IDs do not reach bundled-plugin `dirName` validation and crash the recall run. The same guard already applied to explicit `channelId` params (#76704); this extends it to store-derived channels. (#77396) Thanks @hclsys.
