// VYB LIFE — Social Privacy Foundation

// Step 1 scaffolding only. No Supabase calls, no public exposure.
// All flags here default to OFF. Future "Friends / Public Profile"
// features must read from these constants, not from inline guesses.
//
// DEVELOPER NOTES — Future public profile rules:
//  • Nothing is shared publicly unless the user explicitly opts in.
//  • Even when public profile is enabled, ONLY events listed in
//    SAFE_SOCIAL_EVENT_TYPES may ever be exposed. Habit content,
//    task content, idea text, reading entries, notes, page numbers,
//    book titles (if private), and any free-form text are NEVER
//    exposed by default.
//  • Path/Artifact unlocks are the canonical "safe" social signal:
//    they reveal effort/consistency without revealing personal text.
//  • Friend graph (when added) must be mutual-consent. No follower-
//    style asymmetric exposure in v1.
//  • All exposure must be revocable. Toggling Public Profile OFF
//    must hide previously-shared signals immediately on next read.
//  • Server-side enforcement is required — never rely on client
//    filtering alone. RLS policies must mirror these constants.
