v15.0.5

• Recognize IEnumerable<T> in QYL0013 by its special type instead of its namespace spelling, so a lookalike IEnumerable<T> declared outside System is reported as a type mismatch.
• Report QYL0700 when an OTLP exporter is added without an endpoint.
• Report the catalog migration in QYL0009 when the obsolete constant for a key is not public.
• Use the current constant in the QYL0003 code fix when an obsolete alias holds the replacement key, and the public constant when a private constant holds it.
• Share one OTLP configuration name table, one argument lookup, one literal replacement and one walk over the *Attributes constants across the analyzers and code fixes, and simplify the analyzer value types, collection construction, sub-sequence search and generated-regex options without changing behavior.
• Stop generating the two Markdown references (docs/reference/qyl-semantic-conventions.md and the OpenAI telemetry reference) and their coverage.json, with their templates, script and check. scripts/check-openai-census.mjs replaces the check and reads the resolved registry snapshot and the evidence catalogs directly, keeping every census, native field and evidence-field assertion.
• Delete the Anthropic and browser extension Markdown notes; the vendor registries carry their sources, and AGENTS.md keeps the vendor registry spelling rule.
• List the root files as solution items and name the test-code skill for the pipeline test project in AGENTS.md.
