Build a combine material node for `item_id` carrying `count`. Item ids stay within u16 range so the `item_type` cast the handler matches on is lossles

Deduplicate `(id, amount)` pairs by id, keeping the first amount per id, and project them to evolution materials. Disjoint id ranges across groups kee

Build a varied inventory of filler items drawn from the disjoint id range `2000..3000`, with spare trailing slots. Filler ids never alias a summon tic

Build a `JsonRepository` over a unique temp path so each test seeds a fresh demo world without colliding with sibling tests.

Build an inventory with no spare capacity: `size` equals the slot count and every slot is occupied, so a later grant finds no existing stack to extend

Initialize the persistence backend. Priority: 1. `ODMO_DATABASE_URL` → PostgreSQL (production) 2. `ODMO_DEV_MODE=1` → JSON file (development) 3. Neit

Strategy for a zero-terminated item block `[u8 count][u32 item_id]`. The count byte doubles as the list terminator, so a non-zero count is required: a

Build an item-to-digimon NPC recipe (`exchange_type` 1) that creates `model_id`, costs `price` bits, and consumes every `main_materials` entry (NEED_A

Check the legacy completed-quest bitmap (1 bit per quest id, packed into i32 array).

Read the D-Unit (Union hacking tool) slots installed on a character. Each row represents one unlocked slot. New characters return an empty list.

Replace the character's season pass state.

Write a 1006 entity-body string as `[u2 len LE][ASCII]` (no terminator).

Write a length-prefixed UTF-16LE string: `[u8 code-unit count][units...][u16 0]`. This is the wide analogue of `write_string`, used for variable-lengt

Strategy for a `stCeiling` entry `{u1 tier, u1 value_a, u2 value_b}`. All three fields cover their full wire width so the round-trip is exact.

Load one combine catalog by its variant discriminator, reassembling child rows into their parent rows via id-keyed maps.

Resolve the ceiling-map entries configured for one ceiling tier.

Minimal non-empty combine catalog shared by the Digi Combine and Union Combine demo seeds, which use byte-identical node layouts.

A character carrying a single partner plus a roomy, affordable inventory. Used by the digimon-to-item rejection regimes, where the only intended block

Build a digimon-to-item NPC recipe (`exchange_type` 2) that consumes a partner of type `digimon_type`. The recipe matches only when the partner's leve

Run a Digi/Union combine roll. Union shares Digi's byte-identical layouts, so both flow through here with `is_union` selecting catalog and opcode. Th

Claim the reward for a resolved ceiling tier. The reward block is keyed on `ceiling_type`; a successful claim grants exactly that reward and an invent

Emit the combine ceiling map for the gacha window. The result mirrors the summon sync convention: zero for a populated catalog, one when empty.

Handle a partner attack or partner skill against a target. The target is currently always a mob (PvP and event paths are not yet ported). The HP trans

Read a `u2 count` followed by `count` material nodes `{u4 item_uid, u2 item_type, u2 count}`.

Read a length-prefixed UTF-16LE string: `[u8 code-unit count][units...][u16 0]`. The wide analogue of `read_string`; the count is in UTF-16 code units

Build an account whose `email` and `secondary_password` are known, so a Spirit-craft validation string can be chosen to match or miss the gate.

Strategy for a sync-wire product. Only the four fields that travel on the 3652 wire are randomized; `draw_count` stays within `u16` range so the encod

Round a raw node count down to a whole number of row-groups (a multiple of four), keeping at least one group so the grid is always valid and non-empty

Strategy for one row in the D-Unit (Union hacking tool) response list. The locked flag is a single bit so any boolean is fair game.

Replace the character's premium / silk balances.

Replace the character's digimon archive (storage of dormant partners).

Replace the character's gift storage.
