This v0.1 operational overlay delegates mechanics to existing cnos.cdd
gamma/alpha skills until the v1 role rewrite. Canonical rules live at
../CDS.md §"Selection function".
The 10-rule selection function (P0 override, operational-infrastructure
override, assessment-commitment default, stale-backlog re-evaluation,
MCI freeze check, weakest-axis rule, maximum-leverage rule, dependency
order, effort-adjusted tie-break, no-gap case) plus the four
observation-surface inputs are stated canonically at
../CDS.md §"Selection function". Cite that path.
Mechanics γ runs (read inputs, build candidate table, apply rules in order, name decisive clause, size intervention) — v0.1 overlay:
../../../../cnos.cdd/skills/cdd/gamma/SKILL.md §2.1 — observe + candidate table.../../../../cnos.cdd/skills/cdd/gamma/SKILL.md §2.2 — select by rule order; size.../../../../cnos.cdd/skills/cdd/gamma/SKILL.md §2.2a — peer enumeration at scaffold.When v1 lands, this overlay retires or expands into a full CDS-side skill.
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`.
