## Summary
With T2A packet crafting menus enabled (`t2aCraftMenus`, default for pre-UOTD eras), cooking did nothing. Double-clicking a Skillet set a target, and `T2ACraftSystem.ShowMenu` had no Cooking branch, so the target was accepted and silently dropped. Nothing else could cook either: the old RunUO "use food on a heat source" code was never hooked up and was removed in #1054.
T2A cooking never used a menu, so this restores the item-on-item / item-on-heat-source flow:
- **Per-item handling:** each ingredient (`CookableFood`, `Dough`, `SweetDough`, `SackFlour`, `BowlFlour`, `JarHoney`) implements `IT2ACombinable.TryCombine` and switches on the target. `T2ACooking` holds the shared target, water, combine and heat-timer helpers.
- **Heat source:** all `CookableFood` (raw meats, fish, eggs, unbaked pies/quiche/pizzas, cookie and cake mix), dough → bread loaf, sweet dough → muffins. One unit is used up at the start, then a 5 s timer; the Cooking check runs from `CookingLevel` to 100 (bread and muffins use `DefCooking`'s range). The food burns on failure or if the cook moves more than 3 tiles away.
- **Combinations:**
- Open flour sack or bowl of flour + water → dough
- Dough + pear / peach / apple / pumpkin / eggs / meat / sausage → the matching unbaked pie, quiche or pizza
- Dough + honey → sweet dough
- Sweet dough + honey → cookie mix
- Flour + sweet dough → cake mix
- The honey and flour + sweet dough recipes work in either direction.
- **Water:** water drinks (pitchers), buckets, barrels, tubs and trough add-ons, in the pack, in hand, or on the ground within 2 tiles and in line of sight.
- **Cooking tools are passive:** with T2A menus on, a tool whose system has no T2A menu (`T2ACraftSystem.HasMenu`) falls through to `ShowCraftMenu`, which does nothing under T2A. No dead target is left.
Behaviour with T2A menus off is unchanged.
## Follow-ups
- Static troughs/barrels and open water aren't water sources here or for pitcher filling (no static water ID list exists); to be fixed separately.
- Whether a bowl of flour returns an empty bowl is unconfirmed (`//TODO`).
- Cooking tools that must merely be in the pack for some recipes are not modelled yet.
## Testing
- `dotnet build`: 0 warnings, 0 errors
- New `T2ACookingTests`: flour + water, closed sack refused, dough + apple, honey in both directions, cookie mix, cake mix, wrong target consumes nothing, water in another player's pack refused
- Not covered: the heat timer (untested); not yet exercised in game
## Summary
Folds **113** hand-written `[SerializableProperty]` members into plain `[SerializableField]` declarations using the v4 setter hooks — value coercion/vetoes via `allowFieldChange`, post-change side effects via `fieldChanged` (whose `oldValue` parameter covers the old-house/old-sender unsubscribe patterns). Net **-450 lines** of setter boilerplate.
```cs
// before
[SerializableProperty(1)]
[CommandProperty(AccessLevel.GameMaster)]
public int Charges
{
get => _charges;
set
{
_charges = Math.Clamp(value, 0, MaxCharges);
InvalidateProperties();
this.MarkDirty();
}
}
// after
[SerializableField(1, allowFieldChange: nameof(AllowChargesChange))]
[SerializedCommandProperty(AccessLevel.GameMaster)]
[InvalidateProperties]
private int _charges;
private bool AllowChargesChange(ref int value)
{
value = Math.Clamp(value, 0, MaxCharges);
return true;
}
```
## How sites were selected
A classifier parsed all 204 `[SerializableProperty]` sites and converted only those matching strict shapes: getter is exactly `get => _field;`, the assignment comes first (after at most an equality guard), and relocated side effects contain no `return`, no `value` mutation, and no field re-assignment. Everything else was left alone deliberately:
- **~34 custom getters** (fallback defaults like `_x == -1 ? Default : _x`, self-healing refs) — no setter hook can express these.
- **~35 pre-assignment logic** (durability Unscale/Scale sandwiches, old-state captures like PotionKeg's pile weight).
- **virtual/override members, name-mismatched backing fields (`m_`), exotic semantics** (guards' `Focus` does work on *equal* assignment; `ChampionSpawn.Active` never assigns its field).
Five sites the classifier refused were converted by hand where the hooks fit cleanly: `ReceiverCrystal.Sender`, `PlayerVendor.House`, `PlayerBarkeeper.House` (old-value unsubscribe via `oldValue`), `BaseSuit.AccessLevel` (its existing virtual `OnAccessLevelChanged` already had the exact callback shape), and `DyeTub.DyedHue` (a true veto: `AllowDyedHueChange(ref int value) => _redyable`).
## Verification
- Build: **0 errors, 0 warnings**.
- **Schema regeneration produces zero Migrations changes** — the conversion is wire- and schema-neutral by construction (same orders, types, and property names), and CI's schema diff check enforces it.
- **835 + 708 tests green.**
## Behavioral notes (all strict improvements, called out for review)
- Generated setters skip everything when the incoming value equals the current one; a few converted setters previously re-ran side effects on equal assignment (redundant `Update()`-style refreshes).
- Generated setters always `MarkDirty()` on change; several converted setters never did (e.g. `DyeTub.DyedHue`, `MorphItem` ranges) — their changes only persisted if something else dirtied the entity. Those latent persistence bugs are fixed by construction.
* Adds `SerializationProperty` - This will generate the private variable for serialization. Also provides an option `useField` to specify your own. Example:
```cs
[SerializationProperty(0, useField: nameof(_resource)]
```
