Instrument Parser/HtmlRenderer processing phases with OpenTelemetry @WithSpan annotations so that traces show where markdown processing time is spent: - markdown.parse: Parser.parse(String/BasedSequence/Reader) - markdown.parse.blocks: block parsing loop, extracted into DocumentParser.parseBlocks() (behavior unchanged) - markdown.parse.pre_process_paragraphs / pre_process_blocks / inlines: existing DocumentParser phase methods - markdown.parse.post_process: PostProcessorManager.processDocument - markdown.render: HtmlRenderer.render(Node, Appendable, int), where all public render overloads converge The opentelemetry-instrumentation-annotations dependency is annotation-only (~20KB). Spans are created by a Java agent (dd-java-agent with dd.trace.otel.enabled=true, or opentelemetry-javaagent); without an agent the annotations are inert with no runtime effect.
