…ture check, epoch-hint fix
Propagation is now pull-based: relays page GET /sync (borsh rows ordered by a strictly-increasing per-relay write counter) from verified peers, track persistent per-peer watermarks, and re-verify everything locally (rebuild message per space + chain proof from own spaced + the same handle_message admission as client publishes). POST /poke gives seconds-level propagation: a content-free "pull me" acted on only for verified peers with a fresh cursor, debounced on send and cooled down on receive. /message no longer forwards anything, deleting the gossip amplification problem by construction. Fresh relays bootstrap through the same path; existing DBs are migrated in place (sync_seq backfill). Also lands the reliability/security overhaul from the relay audit: - Rate buckets split read (120/min) / proof (30/min), message 60/min; churn-only content limits (first insert free, replacement charged, burst 3); per-IP limiter maps periodically evicted; rightmost-XFF client IP extraction - Global proof (6) and verify (4) semaphores; HTTP sheds with 503; verification on the blocking pool; veritas behind RwLock - Outbound hardening: connect/total timeouts, no redirect following, peer address policy (http and bare public IPs allowed by design; private/reserved ranges rejected) with DNS results pinned into the connection to close the rebind TOCTOU; bounded /peers and /sync bodies - TOML config (--config / CERTRELAY_CONFIG) for all limits and tuning - GET /stats counters (incl. last sync per peer), unmetered /health, graceful shutdown - storage retention with entitlement-weighted eviction
