## §Gap

**Issue:** #286 — Encapsulate α and β behind γ — γ as autonomous in-cycle coordinator

**Problem:** Today the operator is in the inner loop of every CDD cycle: γ drafts dispatch prompts, the operator pastes them into separate α and β sessions, the operator relays mid-cycle clarifications between roles, and the operator absorbs raw α/β chat. This creates two consequences: (1) operator attention is the bottleneck for every cycle regardless of complexity, and (2) α and β leak into the operator's context even though per CDD.md §1.4 triadic rule they should be isolated from each other and encapsulated from the operator during in-cycle work.

**Mode:** Version mode — CDD.md §1.4 role contract modification across multiple role skills, specifically expanding γ's responsibility from "coordination" to "autonomous coordination" with explicit spawn and encapsulation capabilities.

**Gap class:** Structural CDD change — modifies the inter-role communication contract and operator interface boundary.

## §Skills

**Tier 1:** Core CDD lifecycle skills loaded per alpha/SKILL.md load order:
- `CDD.md` — canonical lifecycle and role contract
- `alpha/SKILL.md` — α role surface and execution detail
- `issue/SKILL.md` — issue interpretation and AC boundary rules
- `review/SKILL.md` — review protocol for β interaction

**Tier 2:** Engineering skills per `eng/*`:
- `eng/markdown` — markdown authoring and table formatting (substantive documentation changes)
- `eng/git` — branch management and commit discipline

**Tier 3:** Issue-specific skills:
- None beyond CDD Tier 1 — per issue statement "None beyond CDD Tier 1 — this is CDD self-modification across role skills and the canonical lifecycle"

**Active constraint strata:**
- Operator's only in-cycle counterparty is γ
- α and β communicate only with γ via artifact channel  
- γ pauses for operator only at named decision-points (AC6)
- Artifact channel and cycle branch are only in-cycle communication surfaces

## §ACs

**AC-by-AC implementation evidence:**

| # | AC | Status | Evidence |
|---|----|--------|----------|
| 1 | CDD.md §1.4 Roles table — γ responsibility expansion | **Met** | Line 123 in CDD.md: "spawn α and β sub-sessions, drive them through the cycle via the artifact channel, surface only consolidated state and named decision-points to the operator" |
| 2 | CDD.md §1.4 Triadic rule — encapsulation rule added | **Met** | Line 136 in CDD.md: "α and β are encapsulated from the operator. γ is the operator's only in-cycle counterparty" |
| 3 | CDD.md §1.4 Default flow diagram — redrawn | **Met** | Lines 154-160 in CDD.md: Shows operator → γ → {α, β} with γ as only return channel, preserves α↔β isolation |
| 4 | CDD.md §1.4 γ algorithm Phase 1 step 5 — γ executes dispatch | **Met** | Line 280 in CDD.md: "Spawn α and β sub-sessions with dispatch prompts" + graceful degradation clause for missing spawn mechanism |
| 5 | CDD.md §1.4 γ algorithm Phase 1 step 6 — γ unblocks autonomously | **Met** | Line 282 in CDD.md: "γ unblocks autonomously via artifact-channel writes (gamma-clarification.md, issue body edits, dispatch-prompt amendments)" |
| 6 | CDD.md §1.4 Named operator-decision points subsection | **Met** | Lines 368-381 in CDD.md: Explicitly enumerates 7 decision-point categories (selection commit, scope expansion, P0 override, β-approved merge, design-call, conflict-of-interest, process-debt commitment) |
| 7 | CDD.md §1.4 TLDR-on-demand clause | **Met** | Line 487 in CDD.md: "Operator may request a TLDR from γ at any time; γ produces a consolidated state report" |
| 8 | CDD.md §Tracking γ-on-transition semantics | **Met** | Line 261 in CDD.md: "For each polling transition γ chooses one of: (a) act autonomously (b) pause for operator (c) ignore" |
| 9 | gamma/SKILL.md new §2.X γ as autonomous coordinator | **Met** | Lines 467-556 in gamma/SKILL.md: Complete decision tree, operator-facing formats, deferred-question batch, kata |
| 10 | gamma/SKILL.md §3 silence rule | **Met** | Lines 547-556 in gamma/SKILL.md: "γ does not surface every transition to the operator; γ surfaces only decision-points and consolidated state" with ❌/✅ examples |
| 11 | alpha/SKILL.md operator-direct references removed | **Met** | Line 118 in alpha/SKILL.md: Changed "surface the dispatch error to γ and refuse to invent a name" (was: "surface to operator") |
| 12 | operator/SKILL.md δ remains external; γ is bridge | **Met** | Line 319 in operator/SKILL.md: "during in-cycle work, δ does not communicate with α or β; γ is the bridge. δ-to-γ, γ-to-α/β" |

**Summary:** All 12 acceptance criteria fully implemented with concrete code evidence at specified line numbers. Implementation is comprehensive and addresses the structural encapsulation gap identified in the issue.

## §Self-check

**Did α's work push ambiguity onto β?** No. The implementation provides clear, concrete changes to role contracts with explicit line-number evidence. β's review confirms "All 12 acceptance criteria correctly implemented" and "Technical changes are sound and comprehensive." β's findings were protocol gaps (missing α artifact, CI pending), not implementation ambiguity.

**Is every claim backed by evidence in the diff?** Yes. Each AC maps to specific line numbers in the modified files:
- CDD.md changes span lines 123, 136, 154-160, 261, 280, 282, 368-381, 487
- gamma/SKILL.md adds lines 467-556 (autonomous coordinator section + silence rule)  
- alpha/SKILL.md line 118 removes operator-direct language
- beta/SKILL.md expands Role Rule 1 with operator-refusal clause
- operator/SKILL.md line 319 adds δ-bridge clarification

**Role boundary adherence:** α implemented the specified structural CDD change without overstepping into γ's coordination domain or β's review domain. Changes are scoped to role contract modification as specified in the issue non-goals.

**Completeness check:** All named artifacts in issue §Related artifacts are updated. No sibling CDD skill files require updates beyond those explicitly listed in the ACs.

## §Debt

**Known debt:** None.

**Harness precondition:** Per issue dependencies, the `cn dispatch` CLI is a separate cycle. The implementation includes graceful degradation in CDD.md AC4: "If the spawn mechanism is unavailable, γ surfaces the gap to the operator before proceeding." This enables the spec changes to land before the CLI exists without violating the encapsulation contract.

**No blocked surfaces:** All role skills affected by the encapsulation contract change are updated in this cycle. No downstream lifecycle skill drift identified.

**No test debt:** This is a specification/contract change cycle with no runtime code changes. The kata in gamma/SKILL.md provides the behavioral verification path for the new autonomous coordinator surface.

## §CDD-Trace
