Term 4. GitHub clears requested_reviewers when a verdict lands, so the field
answers "who still owes a verdict" by itself. Forgejo never clears it —
measured: rig!140 listed all three panelists with all three verdicts in, and
rig!146 still lists three while MERGED, so the field is stale even on a
closed PR.
Read raw on Forgejo that is not a cosmetic over-count. `requested` drives
three decisions, and a permanently-true field pins a PR at
state:bots-reviewing for life and stops blocker:unrequested from ever being
true: the sweep believes a round is live forever and no staleness can
correct it.
So the requested set is intersected with who has NOT submitted a verdict for
the current head, derived from /pulls/{n}/reviews — the read that is true on
both forges. On GitHub the filter removes nothing, because the field is
already accurate; term 5 holds by construction rather than by care.
A STALE approval — an approval of an older head — still owes a verdict. That
is the case that matters: treating it as answered would let a stale round
read as complete, which is the shape #136 exists to prevent.
Mutation-verified both ways: reading the field raw again reds three cases,
and treating STALE as answered reds two.
Also documents @grok-reviewer-andresmgsl's ask (#4763): every panel= account
must be able to read the repo, or the forge refuses the review request —
422 naming the account on Forgejo. A real failure mode for private
consumers, and it fails loudly rather than sweeping blind.
