OpenFUT/openfut-adapter-fifa17/src/fut/content_taxonomy.rs

//! FIFA 17 **non-player content taxonomy** — the evidence-based map from a card
//! `cardsubtypeid` to its functional family (consumables) or role (staff).
//!
//! This is the ONLY place the FIFA-specific `cardsubtypeid` vocabulary lives; it
//! keeps that game concept out of generic Core, exactly as the player-side
//! catalog keeps `resourceId`/`rareflag` out of Core. Nothing here is guessed:
//!
//! * Consumable families and their contiguous `cardsubtypeid` ranges are taken
//!   verbatim from `fifa17-recon/tools/fut_consumables.py`
//!   (`BY_SUBTYPE`/`CORE_KINDS`, Ghidra-derived from `FUN_18013f4d0` /
//!   `FUN_1801bfac0`) and `fifa17-recon/docs/plan-2026-08-06-card-subsystem.md`
//!   (verified against the `.105` `fcc_*.json` tables).
//! * Staff roles are the `FUN_1800d8330` family selector: 4=manager, 5=headcoach,
//!   6=gkcoach, 7=physio, 8=fitnesscoach.
//!
//! Display **labels are functional, never marketing** (e.g. "Player Chemistry
//! Style", not a promo name). A `cardsubtypeid` outside every documented range
//! resolves to `None` — the caller DEFERS it (mirroring the player NoName gate),
//! never fabricating a family.

/// The disjoint content classes a FIFA 17 owned item can belong to. Player is
/// the default so a catalog authored before this taxonomy existed (no `kind`
/// field) still classifies every entry as a player, unchanged.
///
/// The token set is OpenFUT Core's game-independent content vocabulary
/// (`player | manager | staff | consumable | kit | badge | ball | stadium |
/// misc`), so a Core owned row and a FIFA 17 catalog entry name the same class
/// with the same string and the FIFA numerics (`cardsubtypeid`, resource ranges)
/// never leak out of this crate.
