Replace the character's tamer-shop listings.

Write the ceiling map block: `u2 count` followed by `{u1 tier, u1 value_a, u2 value_b}` entries.

Write a material list `[u2 count][{u4 item_uid, u2 item_type, u2 count}...]` in the exact order the combine decoder reads it. Lengths stay within the

Write a modern variable-length string: `[u16 byte-length][UTF-8 bytes]`, no terminator. The byte length is capped at 512 to match the client's read bo

Extract an `Arc<dyn AccountRepository>` from the backend.

Digiclone attribute rows for the partner-detail enchant grid, in the fixed order the detail view renders them: AT, CT, BL, HP, EV.

Skill rows for the active evolution, shown in the partner-detail skill grid. Level comes from the evolution's per-slot skill levels; the slot index ac

Push the full D-Unit state to the client on login so the modern `cUnionContents` can hydrate its hacking grid without an extra request.

Extract an `Arc<dyn CharacterAccountRepository>` from the backend.

Returns the query to fetch a character by ID, for use by drop_repo.

Extract an `Arc<dyn CharacterRepository>` from the backend.

Faithful model of the client 1006 dispatcher `sub_101F50`: a loop that reads `[u1 action]`, runs the matching handler, then reads the next action byte

Seed a minimal combine catalog with one weighted rank and one ceiling entry for `ceiling_type`. The single reward grants `reward_item_id`, kept small

Flatten every ceiling-group entry in the catalog into a single ceiling map.

Defensive server-side re-validation of the 11x4 Material_Grid. Only filled cells travel on the wire, so the per-row grouping is not separable from th

Strategy for a combine material node `{u4 item_uid, u2 item_type, u2 count}`. Each field covers its full wire width so the round-trip is exact.

Strategy for a combine reward node `{n4 item_id, u2 amount, u1 grade}`. Each field covers its full wire width; the encoder zero-fills the reserved tai

Commit a confirmed trade: move items + bits between both sides atomically. Returns silently on any persistence error after rolling back the in-memory

Compute the deterministic partner damage for a single hit/skill. The current formula is intentionally simple — the legacy server's full damage pipelin

Remove exactly the submitted material nodes from inventory. Returns false (with the inventory restored) if any node is missing or insufficient.

Model of a `New`/`In` count-framed handler (`sub_102420` / `sub_102630`): read `[u2 count]`, then consume `count` typed entries.

Consume a digimon (kind 1) body, mirroring `sub_1040E0`'s read order: handle pair, name, size, flag, model, two shorts, a flag, then a fixed block of

Consume one typed entry: a 16-byte header whose third dword carries the entity kind in its high word, then the kind-specific body. An unknown kind con

Consume an item/drop (kind 3) body, mirroring `sub_103210`: `[u4 item_id][u1 form]`.

Consume a monster (kind 4) body, mirroring `sub_104F80`: handle/object pair, two flags, type id, HP/scale base, a float, then a skill/effect sub-count

Consume a tamer (kind 2) body, mirroring `sub_1032C0`: handle pair, name, flag, model, size, condition flag, the 16x69 equipment block plus a 69-byte

The proactive handshake sent on TCP connect. Uses opcode -1 (65535 as u16). Wire: [FF,FF] [HS] [0,0] [0,0] [0,0] [0,0] [0,0] [CK] = 18 bytes

Parse a lowercase-hex string into its byte vector.
