Flag as inferred / Not directly sourced:

• DC Ops = AI compute is an inference from entity naming plus Watcher/permit context, not a standalone filing claim.
• Poolside LF Phase 1 DC Ops LLC is sourced locally only through the datacenter.fyi-labeled event; I did not find a stored Texas SOS record or local raw filing for it.
