v15.0.4

• Describe the OpenAI Codex conversation thread id as openai_codex.thread.id, a string UUID sent under the wire key thread.id, on codex.exec, dispatch_tool_call_with_code_mode_result, startup_prewarm and turn. The core thread.id stays an integer, with its setter, constant and catalogs unchanged.
• Accept both a string and an integer for thread.id in QYL0013. Live checks take the declared type from the span a sample matches, so a Codex UUID under thread.id raises no type error, while text under thread.id on any other span still does. The live-check advice no longer claims the collector coerces a value to the registry type.
• Rewrite a key under a deprecated wildcard prefix to its concrete successor in QYL0009 and its code fix: db.elasticsearch.path_parts.index becomes db.operation.parameter.index.
• Report deprecated values of the qyl packages as QYL0007 with the live [Obsolete] message, instead of the QYL0009 catalog fallback.
• Analyze Gauge<T>.Record tags as a metric measurement, so QYL0601 and QYL0202 apply as on Counter<T>.Add.
• Accept a nullable value of the registry type in QYL0013, such as an int? for server.port.
• Keep surrogate pairs whole when RecordFailure bounds the status description, so it never ends in a lone high surrogate.
• Never suggest an [Obsolete] constant in QYL0004.
• Stop treating XmlElement.SetAttribute and other System methods outside System.Diagnostics as telemetry tag writes in QYL0601, QYL0004, QYL0005, QYL0009 and QYL0013.
• Accept an OTLP endpoint set in top-level statements, a constructor, an accessor or a local function, or passed as a target-typed new(...) Uri, in QYL0700.
• Report graphql.document written through the typed SetGraphqlDocument setter in QYL0001.
• Read short and byte attributes through SpanRecord.GetDouble and GetDoubles, as GetInt64 already does.
• Recognize RPC spans written with rpc.system.name in QYL0002, next to rpc.method and the deprecated rpc.system.
• Order versions numerically in the migration catalog's coverage table, so 1.40.0 sorts above 1.9.0.
