@@ -108,6 +108,7 @@ Docs: https://docs.openclaw.ai
 - Gateway/Control UI origins: support wildcard `"*"` in `gateway.controlUi.allowedOrigins` for trusted remote access setups. Landed from contributor PR #31088 by @frankekn. Thanks @frankekn.
 - Cron/Isolated CLI timeout ratio: avoid reusing persisted CLI session IDs on fresh isolated cron runs so the fresh watchdog profile is used and jobs do not abort at roughly one-third of configured `timeoutSeconds`. (#30140) Thanks @ningding97.
 - Security/Sandbox media reads: eliminate sandbox media TOCTOU symlink-retarget escapes by enforcing root-scoped boundary-safe reads at attachment/image load time and consolidating shared safe-read helpers across sandbox media callsites. This ships in the next npm release. Thanks @tdjackey for reporting.
+- Node host/service auth env: include `OPENCLAW_GATEWAY_TOKEN` in `openclaw node install` service environments (with `CLAWDBOT_GATEWAY_TOKEN` compatibility fallback) so installed node services keep remote gateway token auth across restart/reboot. Fixes #31041. Thanks @OneStepAt4time for reporting, @byungsker, @liuxiaopai-ai, and @vincentkoc.
 - Security/Subagents sandbox inheritance: block sandboxed sessions from spawning cross-agent subagents that would run unsandboxed, preventing runtime sandbox downgrade via `sessions_spawn agentId`. Thanks @tdjackey for reporting.
 - Security/Workspace safe writes: harden `writeFileWithinRoot` against symlink-retarget TOCTOU races by opening existing files without truncation, creating missing files with exclusive create, deferring truncation until post-open identity+boundary validation, and removing out-of-root create artifacts on blocked races; added regression tests for truncate/create race paths. This ships in the next npm release (`2026.3.1`). Thanks @tdjackey for reporting.
 - Security/Node metadata policy: harden node platform classification against Unicode confusables and switch unknown platform defaults to a conservative allowlist that excludes `system.run`/`system.which` unless explicitly allowlisted, preventing metadata canonicalization drift from broadening node command permissions. Thanks @tdjackey for reporting.
