Export Format

The JSON export is the format to use when building tools around captured NTE history. It is cleaned for import/use and does not include raw packet bytes or decoder-only offsets.

JSON shape

{
  "format": "nte-history-export",
  "format_version": 1,
  "game": "Neverness to Everness",
  "source": "packet_capture",
  "capture_source": "npcap",
  "exporter": {
    "name": "nte-history-exporter",
    "version": "0.3.0"
  },
  "banner": {
    "id": "Lottery_Permanent",
    "name": "Standard Board",
    "system": "Monopoly",
    "shared_pity": false
  },
  "scan": {
    "mode": "stable_only",
    "boundary_policy": "export_ordinal_stable_groups",
    "decoded_records": 0,
    "exported_records": 0,
    "skipped_records": 0,
    "warnings": []
  },
  "user_uid": "optional-user-uid",
  "server_id": "23003",
  "account_region": "EU",
  "records": []
}

Top-level fields:

format / format_version: Identify this export format.
game: Game name.
source / capture_source: Where the export came from.
exporter: Exporter name and version.
banner: The history pool this file belongs to.
scan: Export counts and capture warnings.
user_uid: Optional game account UID, if known.
server_id: Optional numeric account-server ID, detected from the initial TCP connection or selected by the user.
account_region: Region code mapped from a known production server_id. Current values are AS, NA_SA, EU, and SE. It is omitted for an unrecognized server ID rather than guessed.
records: Pull/reward records.

Fields to identify pulls

For most tools, prefer these fields:

uid: Stable unique ID for this exported pull/reward row.
user_uid: Account UID, when present. Use this with uid if storing data for multiple accounts.
pool_group_id: Stable pool ID for the record.
banner.id: Stable pool ID for the whole file. This should match pool_group_id on records.
timestamp: Display timestamp from the game history.
timestamp_group_ordinal: Stable ordering inside records that share the same timestamp.
reward_id: Stable decoded reward ID.
reward_type: Reward category, such as character, item, or arc.
quantity: Reward quantity, for Monopoly records.
roll_result / result_type: Monopoly result details.

Current stable pool IDs:

Lottery_Permanent: Standard Board.
Lottery_LimitedCharacter: Limited Character Board. New limited character banners should still use this ID while they share the same history/pity pool.
Arc_MiracleBox: Arc Miracle Box.
Gashapon_MysteryBox: Mystery Box. Records are single pulls and history is not split into event rotations by the exporter.

Avoid using banner.name, reward_name, reward_type or reward_rank as primary IDs. They are useful display fields, but may change when mapping files are updated.

Stability notes

Every JSON record is exported with a stable uid. Re-scanning deeper history can add older rows, but already exported rows keep the same uid.

Limited character banners are grouped by their shared history pool, not by the currently featured character. If the game adds a new visible limited character banner that uses the same pool, tools should continue treating it as Lottery_LimitedCharacter.

If the game adds a genuinely new history pool, the exporter mappings need to be updated before tools can identify it cleanly. Reward display data also comes from the mapping files, so new rewards may export with stable IDs before they have nice names or ranks.

UID generation

The uid is the first 32 hex characters of sha256(source). The game does not appear to send a stable pull/reward row ID, so the exporter builds one from the history pool, raw packet timestamp, and ordinal inside that timestamp group. Decoded content such as dice result, reward ID, and quantity is intentionally excluded so decoder fixes do not change the identity of an already-captured row.

Monopoly source:

nte|monopoly|pool_group_id|timestamp_raw|timestamp_group_ordinal

Arc source:

nte|gashapon|pool_group_id|timestamp_raw|timestamp_group_ordinal

Mystery Box uses the same Gashapon UID source. Reward quantity is preserved, but each record represents exactly one pull and has result_type = single_pull.

}

Achievement export

Achievements are written separately as <user_uid>_Achievements_<date_time>.json. The document contains only records observed in the account's login response; definitions found only in the asset mapping are not synthesized into the export.

        "target": 50,
        "rewards": [
          {"item_id": "Annulith", "amount": 10}
        ]
      }
    ]
  }
}

Achievement fields:

scan.in_game and scan.playstation separate records visible in game from PlayStation trophy records and report completed/in-progress totals.
categories groups records by the prefix of their captured ID. The category is therefore not repeated on every record.
status is completed when completion ticks are present and in_progress otherwise. An observed compound achievement can be in progress while its numeric progress is zero because individual checklist state is server-side.
completed_at is a decoded UTC time for completed records and null for in-progress records.
name, description, quality, target, and rewards are optional display metadata from mappings/achievements.json.
A newly captured ID missing from the bundled mapping still exports its core captured fields; only optional display metadata is omitted.
Asset definitions absent from the network response are not exported because absence cannot distinguish unstarted, locked, or unavailable content.

CSV diagnostics

CSV exports are mainly for debugging the decoder. Tools should prefer JSON unless they specifically need raw packet details.
