Greetings,
We would like to extend the Privacy Sandbox Ads APIs experiment for all APIs contained in the unified origin trial including: Topics, FLEDGE, Fenced Frames, Attribution Reporting, Shared Storage, and Private Aggregation. We are sending a single intent for the extension because the rationale is shared among each of the APIs.

Experimental timeline We'd like to extend the origin trial for 3 additional milestones, with the extension starting in 111 and continuing through Chrome 113. The initial experiment is running from Chrome 101 through 110. We previously requested an extension from Chrome 108 - 110 here <https://groups.google.com/a/chromium.org/g/blink-dev/c/xm9EvnaVBj8/m/6-pwlfryBAAJ> . Any risks when the experiment finishes? None. The unified origin trial is only available for a subset of Chrome users, and requires developers to perform feature detection to use the APIs. Reason this experiment is being extended We received feedback from developers resulting in the need for continued testing and addressing several points of feedback that required changes to the APIs, in the next several milestones. This will allow the ecosystem more time in stable channels to continue their experiments. These improvements include, but are not limited, to the following: Attribution Reporting - Various bug fixes - Support for more debug reports - Support for cross app and web measurement Fenced Frames - Backward compatible API surface change to take a WebIDL object “config” instead of an urn:uuid as a src. - Enhancement of permissions delegation framework to be more compatible with the allow attribute. - Refactoring of reportEvent implementation to be more secure. FLEDGE - Large scale latency optimizations Private Aggregation (OT started in M107) - Limited feedback so far, partners are still ramping up their testing Shared Storage - Limited feedback so far, partners are still ramping up their testing Topics - General utility improvements - Address potential abuse vectors - Performance optimizations Feedback from the ecosystem, especially testing results from our Origin Trials, will continue to influence the evolution of the API. Ongoing technical constraints Please see each API's initial Intent to Experiment. Will this feature be supported on all five Blink platforms supported by Origin Trials (Windows, Mac, Linux, Chrome OS, and Android)? Please see each API's initial Intent to Experiment.
