The latest dispatches
Every update carries a status, date and source. Casting changes remain visible instead of quietly disappearing down a memory hole.
What the labels mean
A simple evidence hierarchy stops an exciting rumour from putting on a fake moustache and passing itself off as news.
OfficialPrimary confirmation
HBO, Warner Bros. Discovery, HarryPotter.com or a named participant speaking on record.
CorroboratedIndependent evidence
Multiple reliable reports, local notices or clearly documented production activity.
UnconfirmedNot established
A plausible report without enough evidence. It stays labelled until stronger sourcing appears.
Useful, commercially honest
Plan the visit. Read the book. Skip the tat.
