Captain Bob, 2026-11-13: "I merge master in". PR 164 could not merge: master's six comment-only commits of 2026-11-11 (751bfe26..268e5593, "record runner.capacity: 1 decision ... (FABRIC-3, #140)") edit the concurrency blocks the branch deletes for #140 ("It should be global"). Resolved in every workflow for the branch -- no concurrency group -- with master's fact kept as a line of the #140 comment: the capacity is explicit in the runner's config.yaml, runner.capacity: 1. Each file parses; scripts/test_acceptance_signing.sh passes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017RzZgrf7V7Zk2iczBXDRbm
