v2-stands per v3 M4 + survey addition: every substrate probe brief must answer the three MDE killers (tool lock-in, round-trip breakage, skill asymmetry) before it runs. Related evidence: orc question-kos-multi-writer-concurrency sub-C (node-write concurrency threshold — at what creation rate does YAML-in-git need the bd Phase 0 treatment). Track B (machine-paid, parallel) per bd aae-orc-b0kp.
