nx_substrate_manifest.nx

nx_substrate_manifest.nx -- declared expected-blob set + completion tracking for the spore-up NETWORK phase. EM-3 partial milestone of NISHI_ECOSYSTEM_EVOLUTION_ROADMAP.md. The spore germinates with a "Merkle root" -- a set of expected blob hashes that together comprise the substrate it will assemble. This primitive captures that expected set + tracks which blobs have been received + verified, so the germination loop can terminate when all expected blobs are present. Transport-agnostic: this primitive doesn't care HOW bytes arrive (HTTPS / sneakernet / file / serial / Bluetooth). The caller hands received bytes + the hash they CLAIM the bytes match; this primitive verifies + stores + tracks. Composes: nx_blob_store -- where verified blobs land nx_sha256 -- hash verification (inside nx_blob_store_put) V1 scope: - Fixed-array expected-hash set (up to NX_SM_MAX_EXPECTED) - Per-hash received_flag: 0 (not yet) / 1 (received + verified) - Ingest verifies: hash matches expected AND expected is in manifest set (refuses unknown hashes -- closes the "peer can push arbitrary content" attack vector) - Idempotent re-ingest: ALREADY_RECEIVED is OK, not error - Canary-bracketed Deferred per roadmap: - Merkle-tree (not just flat set) for O(log n) inclusion proofs - Per-blob freshness timestamps (when did we receive it?) - Per-blob source attribution (which peer served it?) - Larger expected set (V1 caps at 64 expected blobs) genealogy_id: git_pack_index_2005 + ipfs_pinning_2015 + bittorrent_torrent_file_2001 + cardinal_2026-05-20_ecosystem_evolution lineage_id: substrate_manifest_v1 nx_capability_manifest:
