installProviderStallForensics function
void
installProviderStallForensics()
The io composition root for the provider forensics (idempotent; every
seam keeps an earlier install). Call once at host startup — bin/ and
embedding VM apps; the web build never imports this file.
Implementation
void installProviderStallForensics() {
providerStackEnvLookup ??= (name) => Platform.environment[name];
connTraceStderrSink ??= stderr.writeln;
connTraceObservedClientFactory ??= () => IOClient(observeHttpClient());
installStallSentinelDiskSink();
}
