061 shipped statuses: Flow PT REST finding

Q Which Status rows does a site start with, and does anything in the schema mark them?

Endpoint GET /schema/Status/fields ; GET /entity/statuses ; POST /entity/statuses/_search

Docs claim Silent. Status is listed as an ordinary entity type, system is not documented, and nothing says which rows a fresh site holds.

Actual

GET /schema/Status/fields -> 11 fields
  code        text       editable False  "Short Code"
  created_at  date_time  editable False  "Date Created"
  created_by  entity     editable False  "Created by"
  system      checkbox   editable False  "Locked by System"
  icon        entity     editable True   "Icon"

GET /entity/statuses?fields=code,name,system,created_by,created_at,icon -> 32 rows
    id  code   system  created_at            created_by  image_map_key
     1  act    True    null                  null        null  (custom_status/html)
     2  apr    False   null                  null        "icon_apr"
   ... 15 rows, ids 4-19: created_at and created_by null, system True on dis, ip and na
    23  cfrm   True    2014-08-06T15:06:24Z  null        "icon_thumb_up"
    24  pndng  True    2014-08-06T15:06:25Z  null        "icon_voice_command"
    32  pass   False   2025-12-21T07:48:36Z  a person    "icon_apr"
   ... 12 rows, ids 33-198: created_at set, created_by a person, system False

                    system true  system false
  created_by null   6            13
  created_by set    0            13

POST /entity/statuses/_search, hash Content-Type
  created_by is null   -> 200  19 rows
  system is true       -> 200   6 rows
  an `or` of the two   -> 200  19 rows

GET /entity/statuses?options[return_only]=retired -> 200 9 rows
     3 cbb, 13 rdy, 21 blk, 22 plsh, 25 late, 26 rsk, 30 rrq, 31 out   created_by null
    20 tkt                                                             created_by a person

Teaches

created_by is null selects the shipped rows and is the only mark that does. It is one filter at 200, so the split costs no extra call. A row an operator added names them in created_by, and created_by is editable: false, so nobody can blank it afterwards.

system is a checkbox whose display name is Locked by System, and it does not mean "shipped":

selection	on the probed site
`created_by is null`	19 rows
`system is true`	6 rows, `act` `dis` `ip` `na` `cfrm` `pndng`
`system is true` and `created_by` set	0 rows
an `or` of the two	19 rows, the same set as `created_by is null` alone

system is a subset, so an or adds nothing and system alone drops 13 shipped codes.

created_at is not a mark either. On the probed site it is null on 17 of the 19 shipped rows and 2014-08-06 on cfrm and pndng, which no creator names, while every operator-added row from id 32 up has both a date and a person.
The live listing is what the site kept, not what it started with. On the probed site 9 further rows are retired, 8 of them with no created_by (cbb, rdy, blk, plsh, late, rsk, rrq, out), and only options[return_only]=retired returns them. A low id proves nothing on its own: retired id 20, tkt, names a person.

The 19 shipped codes on the probed site, with the stock image_map_key each points at. Resolve a key against the site's own stylesheet and the /images/sg_icon_image_map.png sprite, both of which answer an unauthenticated GET at 200; probe 010 and recipes/010_status_picker record that rediscovery and the offsets.

code	name	`image_map_key`
`act`	Active	none. On the probed site it points at a `custom_status`/`html` icon
`apr`	Approved	`icon_apr`
`clsd`	Closed	`icon_fin`
`cmpt`	Complete	`icon_cmpt`
`dis`	Disabled	`icon_na`
`fin`	Final	`icon_fin`
`hld`	On Hold	`icon_hld`
`ip`	In Progress	`icon_ip`
`na`	N/A	`icon_na`
`omt`	Omit	`icon_omt`
`opn`	Open	`icon_rdy`
`res`	Resolved	`icon_fin`
`rev`	Pending Review	`icon_rev`
`wtg`	Waiting to Start	`icon_wtg`
`vwd`	Viewed	`icon_fin`
`recd`	Received	`icon_recd`
`dlvr`	Delivered	`icon_dlvr`
`cfrm`	Confirmed	`icon_thumb_up`
`pndng`	Pending	`icon_voice_command`

15 distinct keys over 19 codes: icon_fin draws clsd, fin, res and vwd, and icon_na draws dis and na. The icon does not identify the status, and icon is the one editable field on the row, so a stock code can point at a custom icon.

Which codes a site holds is site configuration, and only the shape transfers. Read the split per site rather than hardcoding the 19: this site retired 8 shipped rows and added 13 of its own, and a shipped code is still only offered where a type's valid_values lists it (probe 009).
