## Problem
User report:
```
Buzz Node mismatch: Buzz supplies Node 24.14.0; OpenClaw requires >=24.15.0. All 10 ACP workers immediately crash.
```
Buzz supplies Node to agent processes from two places, and both were
below OpenClaw's floor:
| Supply path | Was | Now |
|---|---|---|
| hermit dev env (`bin/.node-*.pkg`) — the 24.14.0 in the report |
24.14.0 | **24.15.0** (newest hermit publishes; satisfies `>=24.15.0`) |
| Desktop managed runtime (`managed_node.rs` / `managed_node_paths.rs`)
| v24.11.0 | **v24.18.0** (current latest v24) |
The managed runtime sits **first** on the worker PATH
(`managed_agents/runtime/path.rs`), so a user-installed newer Node can't
mask a stale managed one — the pin itself has to move.
## Verification
- SHA-256 digests for all six platform artifacts taken from
`https://nodejs.org/dist/v24.18.0/SHASUMS256.txt`; darwin-arm64
independently re-verified by downloading the tarball (hash match),
extracting, and running `bin/node --version` → `v24.18.0`.
- All artifacts within `MANAGED_NODE_MAX_BYTES` (largest linux-x64 at 57
MB < 90 MB cap); tar.gz layout keeps the `node-vX-platform/bin/node`
shape `verify_node_tree` expects.
- `cargo test --lib` in `desktop/src-tauri`: **1801 passed, 0 failed**
at this commit; `cargo fmt --check` + `cargo clippy --lib -D warnings`
clean.
- Existing readiness check (`node --version == MANAGED_NODE_VERSION`)
makes upgrade automatic: installed v24.11.0 trees fail readiness and the
installer stages v24.18.0 atomically (rename with `.old` rollback —
existing logic, unchanged).
Note: CI `node-version: 24.14.1` pins in
`release.yml`/`windows-canary.yml` are build-env only (already `>=`
nothing OpenClaw touches) and left alone to keep this minimal.
