 - Release validation: install the cross-OS TypeScript harness through Windows-safe Node/npm shims so native Windows package checks reach the OpenClaw smoke suites instead of exiting before artifact capture. Thanks @vincentkoc.
 - Release validation: let Windows packaged-upgrade checks continue after the shipped 2026.5.2 updater hits its native-module swap cleanup fallback, verifying the fallback-installed candidate through package metadata and downstream smoke instead of crashing on the immediate update-status probe. Thanks @vincentkoc.
 - Doctor/plugins: skip channel-derived official plugin installs when another configured plugin is the effective owner for the same channel, so `doctor --repair` does not reinstall `feishu` while `openclaw-lark` handles `channels.feishu`. Fixes #76623. Thanks @fuyizheng3120.
+- Agents/tools: use config-only runtime snapshots for plugin tool registration and live runtime config getters, avoiding expensive full secrets snapshot clones on the core-plugin-tools prep path. Fixes #76295.
 - Agents/bootstrap: keep pending `BOOTSTRAP.md` and bootstrap truncation notices in system-prompt Project Context instead of copying setup text or raw warning diagnostics into WebChat user/runtime context. Fixes #76946.
 - Channels/WhatsApp: allow `@whiskeysockets/libsignal-node` in `onlyBuiltDependencies` so pnpm v9+ `blockExoticSubdeps` no longer rejects the baileys git-tarball subdep and silences all inbound agent replies. Fixes #76539. Thanks @ottodeng and @vincentkoc.
 - Gateway/install: keep `.env`-managed values in the macOS LaunchAgent env file while still tracking `OPENCLAW_SERVICE_MANAGED_ENV_KEYS`, so regenerated services do not boot without managed auth/provider keys. Fixes #75374.
