Your firestore.rules file, read properly — then audited, planned and rewritten
Paste the rules file. Before you sign in or spend anything, a real parser runs in this
browser: it walks every match block, resolves the helper functions, and tells
you which paths are reachable by a stranger, by any account that can sign up, and by the
document's owner. Then pick a stage.
Both examples ship with a saved model run for all three stages, so you can see the whole output — including the rewritten rules file — without signing in and without spending a credit.
