clear_waves	integer [0, 3]	3	0 = Failed in Wave1 3 = Normal waves cleared The result of the Xtra wave (King Salmonid's wave) is not relevant here. For Eggstra Work, you can send [0, 5]

clear_extra	boolean	"no"	Set "yes" if killed the King. Set "no" if you defeat or timed up. Set null or unset otherwise (i.e., the King not appeared)

silver_scale	integer	1	Number of silver scales obtained
bronze_scale	integer	9	Number of bronze scales obtained
job_point	integer	121	job_point = job_score x job_rate + job_bonus (see the image)
job_score	integer	53
job_rate	number	2.29
job_bonus	integer	0	maybe one of 0, 50 or 100
waves	array<Wave struct> (1-4 elements)	[{"tide": "low", ...}, ...]	Waves information. The 4th element is Xtra Wave. For Eggstra Work, you can send 5 elements

note	string		public note
private_note	string		private note
link_url	http-url-string	https://example.com/	IDN is not allowed, it will be public
agent	string (1 ≤ length ≤ 64)	"the super client"	your client name (see the Battle API for details)
agent_version	string (1 ≤ length ≤ 255)	"v1.0.0"	its version

• range (like [1, 4]): See this

• boolean: "yes" or "no". Be careful - it is not a native boolean type, it is a string. (Note: internally, it accepts native boolean value, but the MsgPack library does not support them.)

• http-url-string: HTTP or HTTPS URL. IDN (Internationalized Domain Names) are not supported. It might work if Punycode encode is done on the client side.

• unix-time: integer, seconds from 1970-01-01T00:00:00+00:00 without leap seconds. Be careful if the client using JavaScript -- its time unit is milliseconds, so it must be 1/1000.

• uuid-string: case insensitive string(lowercase recommended), "00000000-0000-M000-N000-000000000000" format, version 1, 3, 4 or 5 is required (M=1, 3, 4, 5). RFC 4122 variant is required (N=8, 9, a, b).

When posting to stat.ink from data obtained from SplatNet, we expect the following method to generate a uuid.
This method IS DIFFERENT with the Battle API.

1. decode Base64'ed ID from coopHistoryDetail.id ("CoopHistoryDetail-u-..." )
2. Calc UUIDv5 with namespace f1911910-605e-11ed-a622-7085c2057a9d

$theUUID = uuid_v5(
  base64_decode($history->id),
  uuid_from_string('f1911910-605e-11ed-a622-7085c2057a9d'),
);
