Why: On a long merge history, git log | grep -q and git log | grep | head -1 could return 141 under pipefail after a recent card match. Precheck then omitted merged cards, and task-close could skip their backfill.
Result: Consume the full merge-log output before deciding a match. Archive and mark complete only the three authorized trial cards for Dev #489, #488, and #486, each with its actual merge SHA. Four other currently eligible cards remain untouched.
Evidence: A disposable long-history test failed before the fix and passed after it (/tmp/mq-card-close-long-history-{red,green}-20261014-01.json). SELF make test-governance passed 341 cases; same-base make task-sync left this fixed HEAD unchanged.

Final exact-head Dev CI is pending and required before merge.
Impact: Reliable merged-card reporting and scoped bookkeeping closure; no product code, component pin, live service, or branch-protection change.

Why: pipefail treated a recent merged-card match as a failed git log after grep exited early, hiding completed cards from precheck and task-close.
Evidence: A disposable long-history regression failed before the fix and passed after it; make test-governance passed 341 cases. Git history confirms PR #489/#488/#486 merge SHAs.
Impact: Detect merged cards reliably and archive only the three authorized trial cards; four unrelated eligible cards remain untouched.
Refs: Dev merge queue #518; Dev #489, #488, #486
Why: The archive move staged the path changes while leaving the status and merge receipts as unstaged content; each archived card must carry its actual completed result.
Evidence: The recorded merge commits f00165e8, d852c159, and 05b997b8 are present in origin/main and match Dev PR #489/#488/#486.
Impact: Mark exactly three authorized cards complete and record their merge subjects without changing other task cards.
