# cdd-iteration — cycle #400

**Author:** γ (collapsed on δ)
**Date:** 2026-05-21
**Cycle:** cnos#400 — Phase 5 of cnos#366; γ shrink

## Findings

This cycle absorbed F1 and F2 from cnos#398's `cdd-iteration.md` and made the managerial-residue sweep a binding γ-side rule. No new outbound findings.

### Inbound absorbed

| Inbound finding | Class | Source | Disposition this cycle | Artifact |
|---|---|---|---|---|
| F1: delta/SKILL.md stale Phase 4b forward-refs | `cdd-skill-gap` | cnos#398 cdd-iteration | landed | delta/SKILL.md L59, L81, L173, L316, L337, L340 |
| F2: delta/SKILL.md frontmatter `requires.1` CUE type mismatch | `cdd-tooling-gap` | cnos#398 cdd-iteration | landed | delta/SKILL.md L30 flat-string fix |

Both findings had a concrete-next-MCA committed in cnos#398; both landed in this cycle as immediate MCAs.

### New findings produced this cycle

None of cdd-skill-gap / cdd-protocol-gap / cdd-tooling-gap / cdd-metric-gap class. The cycle absorbed inbound findings and produced no new ones.

## Patches landed in this cycle

- `src/packages/cnos.cdd/skills/cdd/gamma/SKILL.md`: restructured from 748 → 499 lines; coordination + closure + triage doctrine preserved; runtime-supervision mechanics cross-referenced to harness/SKILL.md and release-effector/SKILL.md; managerial-residue sweep added as binding §3.9 rule.
- `src/packages/cnos.cdd/skills/cdd/delta/SKILL.md`: F1 (5 prose rewrites Phase 4b/4c/5 → past-tense with explicit landings) + F2 (1 frontmatter type fix).

## No-patch findings

None.
