follow sh.E across every channel you use
Pick channels × kinds. Every send is D-KaP-sealed and carries a one-click unsubscribe. Email is fingerprinted (sha256 + RAS + φ) before any seal — your raw address never touches the chain.
privacy posture
· raw email is encrypted-at-rest (AES-GCM, PBKDF2 100k rounds, RAS+φ salt)
· public seals only carry sha256(email|RAS|φ) — never the address
· retention envelope: SEC-17a-4 6-year floor
· one-click unsubscribe in every send + persistent personalized URL
Founder gate (v31 Cloudflare Access bypass):
If /follow returns the Access login wall, the founder needs to add it to the
bypass list (alongside the existing /, /verify*, /feed.xml,
/og/*, /masterclass). Same gate covers /api/follow/*,
/follow/{token}/atom.xml. WAF allow-list addition for the
epochcore-backtest User-Agent (carry-over from v37) closes the synthetic-monitor path.
