# --- the verbs the reconcilers use, over /api/v1 --------------------------
|
|
# Three asymmetries with gh, all measured against this instance on
|
|
# 2026-08-02 using a scratch repo (never a live board):
|
|
#
|
|
# 1. Adding labels takes NAMES POST /issues/{n}/labels {"labels":["x"]} -> 200
|
|
# Removing one takes a numeric ID DELETE /issues/{n}/labels/x -> 422
|
|
# DELETE /issues/{n}/labels/149 -> 204
|
|
# So a removal must resolve name -> id first. gh hides this; the shim
|
|
# cannot.
|
|
#
|
|
# 2. Assignees are SET, not added and removed. PATCH /issues/{n} takes the
|
|
# whole list ({"assignees":[]} clears it, 201), so --remove-assignee is
|
|
# a read-modify-write rather than a delete.
|
|
#
|
|
# 3. There is no statusCheckRollup. The portable equivalent is the
|
|
# combined commit status, GET /commits/{sha}/status, which returns
|
|
# {state, statuses[]}.
|
|
|
|
# forgejo_label_ids — name<TAB>id for every label in the repo, read once per
