Updates the client-side tracing and Edge Function CORS docs for changes shipping in `@supabase/supabase-js` v2.112.3 (supabase/supabase-js#2603, supabase/supabase-js#2604). The tracing guide gains a vendor compatibility table (plain OpenTelemetry works as is, Sentry needs `propagateTraceparent: true`, Datadog RUM needs `allowedTracingUrls`), the new `respectSamplingDecision` semantics (non-sampled requests now carry `traceparent` only, so logs stay correlatable), a troubleshooting entry for the SDK's new propagator warning, and a note that browser calls to Edge Functions need the trace headers in the function's CORS allow-list. The CORS guide now states explicitly that trace headers are sent only when trace propagation is opted in (never by default), adds a table of when each SDK header is actually sent, and the hardcoded `corsHeaders` examples are updated to the full header list. Should merge after the v2.112.3 release is published, since it documents that version's behavior. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Expanded CORS guidance with trace-propagation requirements and SDK version considerations. * Added browser and Edge Function setup guidance for client-side tracing. * Documented updated sampling behavior, advanced configuration, vendor setup examples, and troubleshooting. * **Bug Fixes** * Updated CORS configurations to allow retry and tracing headers required for supported requests. * Improved compatibility for browser requests that transmit distributed tracing context. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com>

Maintainers
If you are a maintainer of any tools in the Supabase ecosystem, you can use this site to provide documentation for the tools & libraries that you maintain.
DocSpec
We use documentation specifications which can be used to generate human-readable docs.
- OpenAPI: for documenting API endpoints.
- SDKSpec (custom to Supabase): for SDKs and client libraries.
- ConfigSpec (custom to Supabase): for configuration options.
- CLISpec (custom to Supabase): for CLI commands and usage.
The benefit of using custom specifications is that we can generate many other types from a strict schema (eg, HTML and manpages). It also means that we can switch to any documentation system we want. On this site we use Next.js, but on Supabase's official website, we use a custom React site and expose only a subset of the available API for each tool.
