project & effort needed in IGWN WBS for delivering an O4 replay ASAP after O4 ends
As soon as possible after the end of O4b, we should set up an O4 replay to support the development and testing of O5 search pipelines and LLAI software. In discussions with @pb, @patrick.godwin and others, it's clear that this is both a non-trivial and ill-defined endeavor involving many people, decisions about how much & what data to replay, decisions (and studies in advance of those decisions) about what software to use to prepare the data for replay (e.g., whether to use fdio -- which will be different from what was used for O3 replay in O4), and lots of other loose ends to systematically understand.
Since this is a well-defined and non-trivial deliverable involving lots of effort, it really needs to be defined as a task with FTE requirements in the whitepaper and IGWN WBS. This is a task for the LL WG chairs.
