Pair-Runner Status

No live-readiness blocker remains for the corrected S1 dynamic-circuit payload. The paired feedback/open-loop runner has superseded this no-submit probe and completed IBM execution:

  • feedback job: d86qn3lg7okc73elg2eg
  • matched open-loop control job: d86qn65g7okc73elg2hg
  • result note: docs/campaigns/s1_ibm_feedback_pair_result_2026-05-20.md
  • analysis: data/s1_feedback_loop/s1_feedback_analysis_summary_ibm_kingston_20260520T123941Z.json

Claim Boundary

This artefact captures live backend metadata and transpilation only. It does not submit IBM jobs and cannot support an S1 hardware-control claim.
