LYDOS Edge encrypts every action to a local SQLite write-ahead log, signs it with ed25519, links it into a per-device hash chain. Network returns → bulk sync → server cryptographically verifies every row before commit.
Generate ed25519 keypair locally, register public key with LYDOS backend.
Each action: signed, hash-linked to previous (prev_hash → curr_hash), idempotency-keyed.
Bulk POST to /api/edge/sync/ingest. Server verifies ed25519 + chain continuity + LSIA veto + idempotent dedup.
Each committed action gets a server-side audit_seq linking it to the sovereign memory chain.
One LYDOS account → install on every device you own. Same edge daemon, same local DB, same ed25519 key sealed to your biometric:
