**Cycle:** [#390](https://github.com/usurobor/cnos/issues/390) — Sub 1 of [#376](https://github.com/usurobor/cnos/issues/376): CDR six-field instantiation contract + architecture-choice declaration
**Date:** 2026-05-21
**Branch:** `cycle/390`
**Pre-merge cycle SHA:** `4eaa1144` (α + scaffold/design-notes/self-coherence) + subsequent close-out commits
**Base SHA:** `417b6227ba7ce7c47e02ec4e8b9614feb70b6f64`
**γ identity:** gamma / gamma@cdd.cnos (γ+α+β-collapsed on δ; per breadth-2026-05-12 wave manifest precedent; β-α-collapse acknowledged in `beta-review.md`)

## §Decision

γ accepts β's APPROVE verdict (R1, no fix-round). Cycle/390 is ready for merge to `origin/main`. Sub 1 of cnos#376 is shipped; AC6 + AC7 of cnos#376 are now met. Sub 2 (package skeleton), Sub 3 (role overlays), and Sub 4 (empirical-anchor doc) can dispatch in parallel against `src/packages/cnos.cdr/skills/cdr/CDR.md` as their doctrinal anchor.

## §Merge Plan

```bash
git checkout main
git pull origin main
git merge --no-ff cycle/390 -m "Merge cycle/390: CDR six-field contract + architecture-choice declaration (#390)

Sub 1 of cnos#376 (CDR v0.1 master). Authors src/packages/cnos.cdr/skills/cdr/CDR.md
declaring all six instantiation-contract fields per ROLES.md §3 in research-loss-
function language, records option (a) (common constitution + per-protocol procedures)
inheritance from cnos#388 for skills (cnos#376 AC7), names the persona/protocol/
project doctrinal boundary (cnos#376 AC6), and cites usurobor/cph as the empirical
anchor with shape-compatibility claim (detailed mapping deferred to Sub 4).

ACs: 6/6 PASS. Rounds: R1 APPROVE.

Closes #390"
git push origin main
```

The merge commit message includes `Closes #390` to auto-close the issue.

## §Post-Merge Cross-References

After the merge lands on `origin/main`, γ posts:

### Comment on cnos#376 — Sub 1 shipped; AC6 + AC7 met

**Content:**

> Sub 1 of #376 shipped via #390 (merged at SHA [merge-sha]).
>
> `src/packages/cnos.cdr/skills/cdr/CDR.md` lands with all six instantiation-contract fields declared per `ROLES.md §3` in research-loss-function language. The file owns this issue's **AC6** (persona/protocol/project boundary) and **AC7** (architectural choice).
>
> **AC6 — Persona, Protocol, Project boundary** (`CDR.md §"Persona, Protocol, Project"`): three doctrinal layers named with canonical homes — persona at `cn-rho/spec/`, protocol overlay at `cnos.cdr/skills/cdr/`, project binding at `<project>/.cdr/`. Rho may play δ for CDR but is not CDR; CDR defines α/β/γ/δ/ε overlays independent of any persona hub; a project binds those roles via its own `.cdr/` directory.
>
> **AC7 — Architecture choice** (`CDR.md §"Architecture choice"`): option (a) common constitution + per-protocol procedures, inheriting cnos#388's schema decision and applying it to skills. Option (b) (common protocol-agnostic skill + domain overlay) rejected with the same five-point rationale transposed from cnos#388: types-first/grammar-is-constitution; clarity at protocol boundary; mechanical generic-vs-domain boundary; future c-d-X generalizes mechanically; decision-once-applied-twice. Decision-record source: `schemas/cdd/README.md §"Architectural choice"`.
>
> **Empirical anchor** (`CDR.md §"Empirical anchor"`): `usurobor/cph` cited as the empirical anchor; shape-compatibility claim with spot-checks across Fields 1/3/4/5; cph's gate verdicts (`bounded GO`, `partial GO`, `INDETERMINATE`, `construct-survives-subject-to-caveats`) mapped onto the CDR vocabulary (BOUNDED-GO, INDETERMINATE) without re-derivation. Detailed surface-by-surface mapping **deferred to Sub 4**.
>
> Sub 2 (package skeleton), Sub 3 (role overlays), and Sub 4 (empirical-anchor doc) can now dispatch in parallel against CDR.md as their stable doctrinal target. Read-through walk in cycle/390 `self-coherence.md §ACs AC6` confirms each Sub-N's expected scope is citable without re-derivation.
>
> ACs met by this sub: AC6 + AC7 of #376 (both owned by Sub 1). The remaining #376 ACs are owned by Sub 2/3/4.
>
> Known debt named in cycle/390 close-out:
> - `cnos.cdr` package skeleton not authored (Sub 2).
> - Role-overlay skills not authored (Sub 3).
> - cph artifact-set full mapping not exhaustive (Sub 4).
> - CDR gate-verdict vocabulary not enum-pinned in `schemas/cdr/receipt.cue` (future cycle if cph or downstream verbs drift).
> - Project-specific stricter actor-collapse-floor policy template not provided (future cycle if/when needed).

## §Debt-Forwarded

(Same list as α/β; preserved here for the γ-side close-out triage.)

1. **Sub 2 package skeleton** — `cnos.cdr/cn.package.json`, package `README.md`, root `SKILL.md`. Dispatch next per cnos#376 plan. Not blocking; CDR.md lives in an otherwise-empty package directory.
2. **Sub 3 role overlays** — `alpha/SKILL.md` … `epsilon/SKILL.md` for CDR. Dispatch after Sub 2 (Sub 3 cites Sub 2's package metadata for git-identity + repo placement conventions).
3. **Sub 4 empirical-anchor doc** — full cph-artifact-to-CDR.md-field mapping. Can dispatch in parallel with Sub 3 (no surface conflict).
4. **CDR gate-verdict vocabulary not enum-pinned in `schemas/cdr/receipt.cue`.** Future cycle if needed; recorded in design-notes §OpenQuestions item 1 + self-coherence §Debt item 4.
5. **Actor-collapse stricter-floor policy template not provided.** Future cycle if a research project requests it; recorded in design-notes §OpenQuestions item 3.

## §Trigger Assessment (per `gamma/SKILL.md §2.8` table)

| Trigger | Fire condition | Fired? | Note |
|---|---|---|---|
| Review churn | review rounds > 2 | No | R1 APPROVE on first pass. |
| Mechanical overload | mechanical ratio > 20% AND findings ≥ 10 | No | 7 β observations + 1 borderline, all confirming or reconciled. AC oracles are mechanical by design for contract-authoring class. |
| Avoidable tooling / environment failure | environment blocked the cycle | No | No environment friction. |
| Loaded-skill miss | a loaded skill should have prevented a finding | No | No findings raised; observations confirm the contract is held. |

No trigger fires. `cdd-iteration.md` is still authored per `post-release/SKILL.md §5.6b` closure-gate (every cycle produces the file; empty findings is itself signal — see §388 ε pattern).

## §Skills-That-Helped

- `cdd/design` — design-half discipline; the L7 design analysis in `design-notes.md` made the architectural-choice section authoring straightforward.
- `cdd/issue/contract` — six-field section structure is contract-shaped; "one section names one truth" applied per field.
- `cdd/issue/proof` — AC oracle authoring; mechanical oracles with line-numbered evidence.
- `cdd/post-release` §5.6b — closure-gate; ensured `cdd-iteration.md` would be authored even with zero findings (#388 missed it once; this cycle does not repeat).
