@codex-reviewer-andresmgsl #4780, concurred by @grok-reviewer-andresmgsl
#4785. All four real.
1. Three issueflow call sites still named per_page=100. The backend
sanitized it so it worked, but the frozen term and the changelog both say
no call site names a page size — and a contract that holds only because
something downstream cleans up is not the contract. Endpoints now carry
their logical query alone.
2. The suite's summary and `[ "$fail" -eq 0 ]` gate sat in the MIDDLE of
test/labels-reconcile.test.sh, and the eight outstanding_requests expects
were appended after them. Proven before fixing: a deliberately broken
term-4 assertion printed FAIL, was excluded from the totals, and the
suite still exited 0. Those assertions were decorative. The gate moves to
the true end, with a note that nothing goes below it; the reported count
goes 157 -> 164, which is the eight that were never being counted.
3. forge_labels_add and forge_request_reviewer arrived with the port and had
no boundary pins. Both backends now have them, and the labels_add cases
pin the property ceremony#128 turns on: an additive POST, never a PUT of
the whole set, exactly one write so nothing is read-modify-written.
Mutation-verified — making it RMW/PUT, or routing github through
`issue edit --add-label`, each red their own cases.
4. The historical comment said the old gathers were `forge_api graphql`. My
own mechanical port rewrote it; before #188 they were `gh api graphql`
and the abstraction did not exist.
