QSDM full node hardened-legacy-20261019-d7ffcd4-hl2-edge-go1269-ids-pqe-rc1019 + snapshot 880376

QSDM full node: hardened-legacy-20261019-d7ffcd4-hl2-edge-go1269-ids-pqe-rc1019 and chain snapshot 880376.

A full node keeps the whole chain and verifies every block itself (block hash, the producer's ML-DSA-87 signature, the
producer transition and the state root). It follows the network over HTTPS from the public API, trusted for
availability only. No inbound port, no mining, no block production. Tested end to end on 2026-10-19.

Before you trust anything here, take the values to pin from https://qsdm.tech/fullnode.html (published
separately on purpose) and check the checkpoint with the public API. Step-by-step guide:

Assets: the signed bundle (qsdm-follower-hardened-legacy-20261019-d7ffcd4-hl2-edge-go1269-ids-pqe-rc1019.tar.gz), the snapshot in two parts (cat qsdm-snapshot-880376.tar.gz.part-* > qsdm-snapshot-880376.tar.gz, then check SNAPSHOT-SHA256SUMS), the ready-made configuration (fullnode-core.toml, checkpoint pinned), the consensus profile and RELEASE-SHA256SUMS.

QSDM is a pilot network with one block producer. Requirements: Linux x86_64, 10 to 12 GB RAM, about 15 GB disk during setup.
