This is at 0x14f, or byte 35 of firstItem.mIngredients.mWork[1].elem.mBuffer. Since the longest item actor name is Get_TwnObj_DLC_MemorialPicture_A_01, which is 35 characters long, this is guaranteed to be 00 already. This is a no-op.

idx == handle, which is mTimeFlag, which is at 0xd4. mCurrentFlagHandlePrefix == 0x00, so this code is checking if the most significant byte of idx is 00. Only if it is will it call fn; otherwise, this is a no-op. 0xd4 in newItem.mName is firstItem.mIngredients.mWork[0].elem.mBuffer[0x8:0xc], which has a 00 as its most significant byte only if firstItem is not a meal or its first ingredient has an actor name shorter than 12 (0xc) bytes long. As mTimeFlag is a handle for an f32 flag, and there are 46 (0x2e) f32 flags, the 3 most significant bytes of the handle must all be 00 in order for this to refer to a valid flag; otherwise, this is a no-op. Hence, the actor name must also be shorter than 10 (0xa) bytes long. All such items are listed below, along with which flag they correspond to.

Actor name	Handle	Flag	Success?
`BeeHome` (Courser Bee Honey)	`0x00000000`	`dummy_float`	❌
`IceArrow` (Ice Arrow)	`0x00000000`	`dummy_float`	❌
`FireArrow` (Fire Arrow)	`0x00000077`		❌

As no items with actor names shorter than 10 bytes long refer to valid and readable flags, this line is a no-op.

Some of these flag reads are conditional, and their conditions include member variables. These members corresponding to the following members of PouchItem:

Member/Offset	`PouchItem` Member	Result
`mBloodyEndReserveTimerFlag` (`0x124`)	Most significant dword of `firstItem.mIngredients.mWork[1].elem.mStringTop`	`true`
`mPlayedDemo103Or997` (`0x14d`)	`firstItem.mIngredients.mWork[1].elem.mBuffer[0x21]`	`true` if a `true` flag hasn't been written here yet and `firstItem`'s 2nd ingredient, if any, is not the Picture of the Champions, otherwise `false`
`mFindDungeonActivated` (`0x14e`)	`firstItem.mIngredients.mWork[1].elem.mBuffer[0x22]`	Whether `firstItem`'s 2nd ingredient, if any, is not the Picture of the Champions

if (mNewTime >= 0.0 && (
  mTimeUpdateMode == TimeUpdateMode::Forced
  || mTimeUpdateMode == TimeUpdateMode::Normal
)) {
  mTime = mNewTime;
  mNewTime = -1.0;
  wm->getSkyMgr()->onTimeUpdate();
}

mNewTime is at offset 0xc0, which corresponds to the least significant dword of firstItem.mIngredients.mWork[0].elem.mStringTop. Since >= 0.0 is a sign check, both 0.0 and -0.0 are equal to 0.0, and the sign is the most significant bit of a float, this is essentially a <= 0x80000000 check. Due to ASLR, this is unpredictable, but has a slightly higher chance of being false due to addresses 0x0000000000000000-0x0000000007ffffff being outside the ASLR range.
mTimeUpdateMode is at offset 0x149, which corresponds to firstItem.mIngredients.mWork[1].elem.mBuffer[0x1d]. Actor names will never contain the byte 0xff (TimeUpdateMode::Forced), so the only option is for this to be 0x00 (TimeUpdateMode::Normal), meaning the name must be at most 0x1d (29) bytes long for the condition to be true. This is true for every item except the Picture of the Champions (Get_TwnObj_DLC_MemorialPicture_A_01), which has the longest actor name of any item at 35 bytes. The condition will also be true if firstItem is not a meal or only has 1 ingredient.

If the condition is true, the following will happen:

mNewTime is read from offset 0xc0, which corresponds to the least significant dword of firstItem.mIngredients.mWork[0].elem.mStringTop, and copied to mTime, which is at offset 0xb8 and corresponds to the least significant dword of firstItem.mIngredients.mWork[0].elem's vptr.
mNewTime (least significant dword of firstItem.mIngredients.mWork[0].elem.mStringTop) is set to -1.0f, or 0xbf800000.

if (mNeedToHandleNewDay) {
  handleNewDay(HandleNewDayMode::Forced);
  mNeedToHandleNewDay = false;
}

mNeedToHandleNewDay is at offset 0x148, which corresponds to firstItem.mIngredients.mWork[1].elem.mBuffer[0x1c]. Since a bool being anything other than true or false is UB, checking the executable shows that this specific check uses a cbz (Compare and Branch on Zero) instruction. Similarly to the mTimeUpdateMode check, the name must be longer than 0x1c (28) bytes for this byte to be nonzero, and, again, the only item with an actor name this long is the Picture of the Champions, so this will only be true if firstItem is a meal with at least 2 ingredients and its second ingredient is the Picture of the Champions.

// void TimeMgr::handleNewDay(HandleNewDayMode mode)
++mNumberOfDays;

mNumberOfDays is at offset 0x13c, which corresponds to firstItem.mIngredients.mWork[1].elem.mBuffer[0x10:0x14], so mBuffer[0x10] will be incremented, either changing the ingredient, invalidating it, or adding a 01 byte to the end (also invalidating it).

if (mode == HandleNewDayMode::Normal && wm->getEnvMgr()->isBloodMoonNight()) {
  // ...
}

mode is HandleNewDayMode::Forced, so the condition is false.

if (gdm) {
  gdm->getBool(mBloodyDayFlag, &mWasBloodyDay);

  if (playerHasLeftPlateau() && mBloodMoonTimer > 7_days) {
    mBloodMoonTimer = 0.0;
    gdm->setBool(true, mBloodyDayFlag);
  }
  else mBloodyEndReserveTimer = 150;
}

// worldTimeMgr.cpp
static bool playerHasLeftPlateau() {
  bool left_plateau = false;
  gdt::Manager::instance()->getParamBypassPerm().get().getBool(
    &left_plateau, "FirstTouchdown"
  );
  return left_plateau;
}

// worldTimeMgr.h
constexpr float operator""_days(unsigned long long days) {
  return timeToFloat(static_cast<int>(24 * days), 0);
}

constexpr float timeToFloat(int h, int m) {
  return float(h) * 15.0f + float(m) * (15.0f / 60.0f);
}

mBloodyDayFlag is at offset 0x11c, which corresponds to the most significant dword of firstItem.mIngredients.mWork[1].elem's vptr. This allows reading any boolean flag in the range 0x00-0x7f into mWasBloodyDay, which is at offset 0x152 and corresponds to firstItem.mIngredients.mWork[1].elem.mBuffer[0x26]. Since no item actor names are longer than or equal to 0x26 (38) bytes, this is effectively a no-op.

mBloodMoonTimer is at offset 0xc8, which corresponds to firstItem.mIngredients.mWork[0].elem.mBufferSize. Since this is always 0x40, interpreting it as an f32 gives 8.96831017167882925391e-44. This is not greater than 2520.0f, so mBloodyEndReserveTimer (offset 0x144, firstItem.mIngredients.mWork[1].elem.mBuffer[0x18:0x1c]) is set to 150 (0x96), invalidating the actor name if it was the Picture of the Champions.

};

mNewDaySignal is at offset 0x80, which corresponds to firstItem.mData.mSellPrice/firstItem.mData.mModifier, firstItem.mData.mEffect, firstItem.mData.mEffectLevel, padding, firstItem.mIngredients.mPtrNum, firstItem.mIngredients.mPtrNumMax, and firstItem.mIngredients.mPtrs. mList is at offset 0x8 in sead::DelegateEvent<T>, and mCount is at offset 0x10 in sead::ListImpl, so getNumSlots() returns the s32 at offset 0x18 from mNewDaySignal, which is the least significant dword of firstItem.mIngredients.mPtrs. This will never be 0, so the only requirement is for it to be positive, or for the sign bit to be 0. This is unpredictable due to ASLR. If the condition is true, the following will happen:

The for loop begins iteration at mList.robustBegin(), which is robustIterator(static_cast<TListNode<T> *>(mStartEnd.next())). mStartEnd is at offset 0x0 in sead::ListImpl, and mNext is at offset 0x8 in sead::ListNode, so a pointer is read from offset 0x10 from mNewDaySignal, which is mPtrNum and mPtrNumMax. mPtrNumMax will always be 5, and there is very little control over mPtrNum, being 0-5, so this will not point to a valid pointer. It is immediately dereferenced with -> in explicit robustIterator(TListNode<T> *ptr), crashing the game.
