PID Type and Origin Seed

[burb00]

Questions about PID type and origin seeds.

1.) Can i know what are these in short and whether they are important in creating a legal Pokemon.

2.) When i shinify a pokemon, it's pid type will be cleared and origin seed will no longer be shown. Is this normal? (Eg: SwSh max lair and LA wild encounter)

3.) Some pokemon encounter from LA does not have pid type and origin seed shown, possible for it to happen? Cause for my current understanding is that all Pokemon encounter from LA must have a origin seed for it to be legal.

1. If the Pokemon is generated with a detectable pattern, then it must have a recognizable pattern in order to be legal.

2. If the Pokemon is generated with a pattern that isn't detectable (sufficiently random) then it won't show a pattern or lack thereof. Patterns that are too difficult to detect in realtime are not checked. 

3. See #2; difficult to detect are not checked by the program. Verifying shiny raids and spawned PLA Pokemon with bonus shiny rolls takes a few minutes to bruteforce, and there are no public tools for anyone to use.
