[finding] check-issue-citations enumerateBoard takes a short walk as the whole board: no rel="next" ends it and the highest number seen becomes the frontier (seen once: 126 of 184 pages, 9,160 phantoms) #20557

enumerateBoard(scripts/check-issue-citations.mjs) ends its walk on a missingLinkheader and takes the highest number it saw as the frontier. It was seen once, on the report-only--census, and not reproduced on the re-run minutes later.Why it closes. The fix lands in a gate script, so this is
tooling. Under the #202 B reading, atoolingcard needs anUnblocks:line or a named shipped surface, and this card has neither. The one measured run was the report-only census. The blocking diff verdict takes the enumerate path only past 400 distinct numbers, and no pull request has been measured refused by a phantom.It re-enters
pm:queueon either of these, and triage re-grades it then:- A pull request is refused by the blocking citation verdict on a number the short walk misclassed as
never-issued. That is a measured wall on a landing, with its run id. - It gains an
Unblocks:line naming a card this fix unblocks.
The suggested cross-check (read the newest number as
probeBoarddoes, and refuse on a short walk) stays on this card as the direction for that day.- A pull request is refused by the blocking citation verdict on a number the short walk misclassed as
Filing gate: ① a gate defect with a measured reach. Finding class (a).
reach:node scripts/check-issue-citations.mjs --census, the report-only census the half-state patrol reads; the blocking diff verdict is affected too, but only on the enumerate strategy, which a diff takes past 400 distinct numbers. Observed once, and not reproduced on an immediate re-run. The code path that allows it is certain.Filed by the

At PR #20554's head

enumerateBoardinscripts/check-issue-citations.mjs(:491onorigin/mainb05743433b):issues?state=all&per_page=100&sort=created&direction=ascuntilparseNextLinkreturnsnull. A page whoseLinkheader is missing or truncated (a proxy or transport hiccup) therefore ends the walk early.frontier: Math.max(...numbers)from what it saw. A short walk thus lowers the frontier, and every real number above it is classednever-issued.Its sibling
probeBoard(:520) reads the frontier directly:issues?state=all&per_page=1&sort=created&direction=desc. The enumerate strategy has no such cross-check.Suggested shape (⛔ not a ruling)
After the walk, read the newest number the way
probeBoarddoes. Refuse the run (a read failure, exit 3) when the enumerated maximum falls short of it by more than the numbers created during the walk. Add a self-test case with a stubbed transport that drops theLinkheader midway, which must fail loudly rather than answer.Dedupe
