# cdd-iteration — cycle/415

**Issue:** [cnos#415](https://github.com/usurobor/cnos/issues/415)
**Date:** 2026-05-22
**Cycle:** 415 (Sub 1 of cnos#404 wave)
**Receipt status:** `protocol_gap_count: 0` — courtesy stub per backward-compatibility allowance

## Cadence

Per `cnos.cdd/skills/cdd/post-release/SKILL.md §5.6b` cadence rule: `cdd-iteration.md` is required only when `protocol_gap_count > 0`. This cycle's receipt carries `protocol_gap_count: 0`; the artifact is **optional**. This stub is written as courtesy (backward-compatibility allowance per §5.6b — empty-findings files remain valid artifacts).

## Findings

None.

- 0 `cdd-skill-gap` findings
- 0 `cdd-protocol-gap` findings
- 0 `cdd-tooling-gap` findings
- 0 `cdd-metric-gap` findings

No findings of any class. No patches landed; no MCAs filed; no `no-patch` reasons recorded.

## Why no findings

The cycle's matter was bootstrapping a new package skeleton + extraction map against a structural precedent (cnos.cds Sub 1 at cnos#406, merged 2026-05-22 as commit `378a54f0`). The precedent provided verbatim shape templates for `cn.package.json`, `README.md`, `skills/<pkg>/SKILL.md`, and `docs/extraction-map.md`. α's authoring task was largely transcription with name substitution (`cds` → `handoff`; CDS-specific section content replaced with handoff-specific content per cnos#404's surface inventory and the cnos#415 D2 requirements).

No protocol gap surfaced because:

- The dispatch contract was complete (γ scaffold + 7-axis implementation contract + 9 ACs + δ-pinned package name).
- The precedent (cnos#406) covered every doctrinal question the agent might have improvised on.
- The extraction-map authoring required judgment (J1–J4 in gamma-scaffold.md), but the judgment was structurally bounded by the source surfaces in cnos.cdd / cnos.cds and the cnos#404 + cnos#415 issue bodies; no skill-gap was needed to make the calls.

## Cross-repo trace

None. No findings with `patch-landed` + `Cross-repo` disposition.

## Aggregator update

Appended to `.cdd/iterations/INDEX.md`: row for cycle 415 with `Findings = 0; Patches = 0; MCAs = 0; No-patch = 0`.
