Verdict: the failing CI job on commit 6132b4a is a guard false positive, not count drift.
Reproduced and verified everything against the real get-h3/sdk-go repo. The solution is written to ~/solution.md; here it is:
get-h3/sdk-go, tick #251Verdict: the failing CI job on commit 6132b4a is a guard false positive, not count drift.
scripts/check-test-count.sh exit 1 was caused by the retired-count regex
4[345]/[0-9]+ matching the GAP-id chain GAP-041/042/045/046 (substring 45/046) in a
dated report that never quoted a battery count. The suite count matched exactly
(suite=130 vs. live 130). Fix = the guard's own prescribed point-in-time banner to
unblock CI plus anchoring the regex and filing the false-positive class as its own
low-priority board row (GAP-055).
Build & Test (1.26), step Compliance-test count guard (run: sh scripts/check-test-count.sh, .github/workflows/ci.yml:29-30) fails on 6132b4a.The guard has six checks. Checks (a) canonical parse, (b) suite parity, and (c) battery parity all passed at 6132b4a:
scripts/test-count.txt says battery=46, suite=130.go test ./... -list '^Test' | grep -c '^Test' = 130. Parity holds.The failure came from the retired-literal sweep:
# scripts/check-test-count.sh (line 178 at 6132b4a)

The alternative 4[345]/[0-9]+ is unanchored. In the dated report docs/dogfood/2026-09-18-integration.md line 224:
- Evidence that the 09-01 dogfood P2s (5 rows) and GAP-041/042/045/046 remain
the substring 45/046 matches 4[345]/[0-9]+. The file never quoted a battery count. Because it is under docs/dogfood/2026-*, check (f) demands a historical banner; since there was none, the guard exited 1:
FAIL: docs/dogfood/2026-09-18-integration.md quotes a retired count with no point-in-time banner.
The awk canonical-claim sweep does not fire here, because it requires the denominator to differ from both canonical totals, and 046 → 46 equals the current battery=46. Only the unanchored shell regex was wrong.
