- otlp_exporter hosts SDK loading (symbol table), header/endpoint/resource helpers shared with gateway_health_export; export module imports them instead of keeping copies (_otlp_config/_resolve_headers/_install_id/_safe_resource_attributes unified). _KEEP_BY_KIND attribute allowlist reused for diagnostic log attrs. - events: _MonitoringEvent base supplies to_dict; field order (wire order) unchanged. - redaction: redact_bounded() replaces 3 inline redact+truncate try/excepts. - EmitterStreamer base owns the shared unsubscribe/flush/shutdown for OTLPStreamer and GatewayDiagnosticLogStreamer. - gateway_health: metric construction helpers, _contains_any shared with cron_health, dead _allowed_logger/redact_gateway_message removed (0 refs). - Comment/docstring compaction keeping every stated invariant.
