std79 DoE campaign rerun post-Stage-4: 81/81, §XIV caught live by rerun's own harness bug (FABRIC-3.md §XXXI)
Reran the established 3x9x3 randomized full-factorial campaign (std79-doe.fth) on all 3 architectures per standing project discipline (any Stadium-adjacent change reruns the whole DoE from the top). First amd64 attempt exposed a real test-harness bug that re-triggered the already-known §XIV concurrent-attach gap: the sequential-attach wait loop checked for any recent WIREBIND-attached line instead of the specific identity requested, firing the next device_add before the kernel finished the current one. Only 2 of 8 identities attached; the campaign itself completed cleanly with graceful "VM-EXEC: VM not found" refusals rather than corrupting anything. Fixed the wait loop, discarded the invalid run's campaign result (its boot log kept for the record), reran clean. Corrected reruns: all 8 identities individually confirmed on all 3 architectures, zero VM-not-found errors, zero faults, 81/81 trials correct against established baseline values. Raw logs archived at experiments/std79-doe/results-20260915-stage4/. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01BWpNjdwPtFLuVLaAq44L9K
