About the Current PID Reroll Button's Behavior in Latest PKHeX

[sumo]

Hello,
I've been using PKHeX for many years now — thank you so much for the continuous development and updates!When editing wild Pokémon in Pokémon Scarlet/Violet, I usually follow this order:
Randomize IVs → Set Nature → Reroll EC → Reroll PID
(For shiny versions, I use Ctrl + the star icon instead of the regular PID reroll button.)My understanding is that the PID Reroll button automatically calculates a new PID based on the current IVs and Nature (to try to keep them consistent where possible).
Is this correct? Or does it simply generate a completely random PID string without taking the current IVs/Nature into account?I'd really appreciate it if someone could explain the exact current behavior/specification of the PID Reroll button in the latest version of PKHeX.
Thank you very much in advance!

For gen3/4 it rerolls to give a PID that matches the Nature, Ability, and Gender.

For gen5, it rerolls to give a PID that matches the Gender (and ability?).

For everything else, it's just random.

55 分前、Kaphotics は次のように述べました:

gen3/4では、性質、能力、民族に一致するPIDを付与するために再ロールされます。

gen5 では、国家 (および能力?) に一致する PID を考慮して再ロールされます。

その他はすべてランダムです。

Thank you for the quick and clear explanation on the regular PID reroll button!As a follow-up, for shiny Pokémon (especially wild encounters in Scarlet/Violet), when I use the Ctrl + Star icon button instead:

1. 1 Does this generate a PID that fully replicates the game's actual wild shiny RNG (e.g., for non-Tera Raid encounters like overworld grass or outbreaks)?
   Or is it a simplified method (e.g., just calculating a TSV/FSV-compatible PID)?
2. 2 What's the exact behavior of this button in the latest PKHeX?
   Does it take into account the current IVs, Nature, EC, Gender, or Form to ensure legitimacy,
   or is it independent/random like the regular PID reroll?
3. 3 For best practices to keep wild shiny edits 100% legal:
   ・ Should I always reroll PID after setting IVs/Nature/EC?
   ・ Any specific order or additional steps (e.g., re-reroll EC afterward) to match game data perfectly?
   ・ Does the Legality Checker automatically validate these shiny PIDs under "Wild Encounter" template?

I'd love any code references or tips for batch editing multiple shinies too.
Thanks again!
