**Date:** 2026-05-21
**Issue:** [#394](https://github.com/usurobor/cnos/issues/394)
**Branch:** `cycle/394`
**β identity:** beta / beta@cdd.cnos
**Outcome:** R1 APPROVE; 6/6 ACs PASS.

## §1 Review evidence

See `.cdd/unreleased/394/beta-review.md` for the mechanical AC re-check. Summary:

| AC | Oracle | Result |
|---|---|---|
| AC1 | `jq -e '.name == "cnos.cdr"'`; schema parity with cnos.cdd | PASS |
| AC2 | `test -f README.md`; `rg -c "CDR.md"` ≥ 1 | PASS (8 hits) |
| AC3 | `test -f SKILL.md`; frontmatter fields present; loader pattern | PASS |
| AC4 | `cn build --check` lists cnos.cdr | PASS (`✓ cnos.cdr: valid`) |
| AC5 | `rg "CDR.md"` in README + SKILL.md ≥ 2 | PASS (18 hits across two files) |
| AC6 | No role-overlay procedural content; no empirical-mapping prose | PASS |

## §2 β-side findings

### F1 (β) — `cn build --check` does not enforce skill `calls:` path existence

Discovery: the package-validation oracle validates manifest schema only; it does not walk the skill `calls:` graph to verify referenced files exist. cnos.cdr's loader names `alpha/SKILL.md` ... `epsilon/SKILL.md` in `calls:` as forthcoming Sub 3 files; these paths do not exist; `cn build --check` still passes. **Class:** observational; the design is consistent. **Disposition:** carry as forward-looking debt for Sub 3 dispatch context — if a stricter loader is introduced before Sub 3 ships, the loader will need a "forthcoming" marker. No immediate patch; mentioned in `cdd-iteration.md`.

### F2 (β) — β-α collapse is reconciled per class

The cycle ran with γ+α+β-collapsed-on-δ. Per CDR.md Field 6, α=β is always prohibited for research-class claim transmission. β verifies that this cycle is **not** research-class: it is engineering-class docs-and-metadata under repairable feedback (any AC failure would be caught by `cn build --check` and trivially patched). The collapse is consistent with engineering-class precedent (cycles 375/377/378/388/390). No discipline violation. Same disposition as cycle 390's beta-review borderline observation.

## §3 Merge evidence

To be filled by γ post-merge:
- `cycle/394` HEAD SHA: `[γ fills]`
- merge commit SHA on main: `[γ fills]`
- `Closes #394` in merge commit message: `[γ fills]`
- cnos#376 close-out comment URL: `[γ fills]`

## §4 What β did not do

- β did not author any of the three deliverable files (those are α's authorship).
- β did not modify CDR.md (Sub 1's deliverable; out of scope per `Non-goals`).
- β did not run kata tests or any test suite beyond the AC oracles named in the issue (the cycle is docs-and-metadata; no test surface exists to run).
- β did not run `go test ./...` for the full repo (out of scope for a package-skeleton cycle; the only Go code that interacts with cn.package.json is `src/go/internal/pkg`, which β verified passes: `ok github.com/usurobor/cnos/src/go/internal/pkg 0.008s`).

## §5 Hand-off

β-side closeout complete. γ proceeds to gamma-closeout + cdd-iteration + INDEX + merge.
