The last two Phase 0 seams:
- Core\Cluster\NodeRpc wraps every ApiClient::systemRequest() and
asyncRequest() call. It covers 37 call sites across the admin
controllers, the admin API wrapper, ServerRepository/ServerService,
StreamService, DiagnosticsService and AuthRepository. The HTTP transport
is unchanged. In Phase 4 these become node.rpc{action} commands.
- Core\Cluster\NodeActions wraps every SignalDispatcher::rootAction() call
(26 sites) with typed methods: reboot, restartServices, update,
rollback, updateBinaries, setRamdisk, setPorts, setServices,
setGovernor, setSysctl, flushBlocklist, certbot. send() takes payloads
the caller builds (modules, OPENSSL_EXTRA). The queued JSON is
byte-for-byte what the callers wrote. In Phase 4 these become
node.root{action} commands.
Each seam refuses an action outside its catalogue (NodeRpc::ACTIONS,
NodeActions::ROOT_ACTIONS). NodeRpcActionsTest checks that:
- every call site uses a catalogued RPC action;
- RootSignalsCronJob handles every catalogued root action;
- nothing outside Core\Cluster calls the raw functions.
docs/en/development/cluster-seams.md lists all the Phase 0 seams, their
legacy backends and the rules for new code.
