Based on SOC occupation classification
α role in CDD. Implements the selected change, produces the review-ready artifact set, and writes α close-out.
β role in CDD. Reviews the change, merges on approval, and writes β close-out. δ owns the release boundary (tag/deploy/disconnect).
Compatibility pointer. Cross-repo handoff doctrine has moved to cnos.handoff/skills/handoff/cross-repo/SKILL.md as of cnos#416 (Sub 2 of cnos#404 handoff extraction).
δ role-skill. Owns the two-sided coherence-cell membrane (outward boundary decision on receipt + V verdict; inward implementation-contract enrichment at dispatch) and the override authority that compose with V's verdict per RECEIPT-VALIDATION.md.
Produce the design artifact for a substantial change: incoherence, challenged assumption, impact graph, acceptance criteria, and leverage.
ε role in CDD — the CDD-specific instantiation of the generic ε doctrine. Reads receipt streams across cycles, surfaces `cdd-*-gap` findings, applies MCA discipline, and writes `cdd-iteration.md` when the cycle's receipt has `protocol_gap_count > 0`.
