# ε cdd-iteration — cycle/428

**Issue:** [cnos#428](https://github.com/usurobor/cnos/issues/428) — `CELL-OF-CELLS.md` v0.1.0 → v0.2.0 (formalized composition law + consequences + anti-scope).
**Mode:** docs-only; β-α-collapse-on-δ. Per ε hygiene, empty findings are recorded explicitly.

## Findings

**None.**

This was a docs-only cycle producing exactly 1 substantive file change — content replacement of `docs/gamma/essays/CELL-OF-CELLS.md` from v0.1.0 to v0.2.0 (657 → 741 lines). No tooling, no schemas, no build/test surface, no code was touched. The cycle had no review-oracle ambiguity, no β-α dispatch round (β-α-collapse-on-δ explicitly), no protocol-shape disagreement, no out-of-band coordination friction. The δ-pinned 11 ACs are mechanical; α executed within them; β confirmed conformance.

## Protocol-gap signals (across receipt-stream)

**None surfaced this cycle.**

## Non-findings (worth recording)

- **Operator seed was the substantive source.** The issue body provided the operator's v0.2.0 seed verbatim inside a `Verbatim content` markdown fence with mojibake-cleaned text. α copied as-is and ran the cycle/414 substitution table as defensive sanity check rather than as primary editing work. The Hard Rule against α-redraft held cleanly because the oracle for "did you redraft?" is a diff against the seed, which is mechanically inspectable in the issue body.

- **AC oracle granularity worked.** The 11 ACs decomposed naturally into structural (AC1, AC2, AC3, AC4, AC5), Unicode-hygiene (AC6, AC7), content-presence (AC8, AC9), and scope (AC10, AC11) bands. Every band returned PASS on first run after α's apply. No re-apply round was needed. This is the kind of mechanical AC grid that lets β-α-collapse-on-δ run safely for skill/docs-class cycles.

- **v0.1.0 → v0.2.0 vs new-essay distinction.** Cycle/424 authored CELL-OF-CELLS.md v0.1.0 with the original recursive-coherence-cell thesis. Cycle/428 supersedes that draft with v0.2.0, which adds the formalized composition law (§8 pseudocode with explicit δ-decision branches), six pinned consequences (§16), explicit anti-scope (§17), and six open questions (§18). The diff is substantive but the contract surface (essay file path, role in Reading Order) is unchanged. README pointer correctly remained version-agnostic ("DRAFT" without a pinned version) per the cycle/424 convention, so no companion-essay edits were required.

- **β-independence collapse posture.** This cycle ran as `β-α-collapse-on-δ` per the dispatch brief. Per `COHERENCE-CELL.md §β Independence as Contagion Firebreak`, this would normally collapse β's structural independence and close-as-degraded on the structural-independence axis; but the mechanical AC oracle stands in as the independent discriminator for docs-class work, which is the immunology firebreak that makes the collapse structurally safe. The disposition is named in `beta-closeout.md` and `gamma-closeout.md` rather than hidden. Positive observation; no gap.

## Verdict

No ε action required. No protocol patch to file. No follow-on Sub to spin.

`protocol_gap_count: 0`.

This courtesy stub is filed per `cnos.handoff/skills/handoff/receipt-stream/SKILL.md` close-out shape (cdd-iteration.md required when `protocol_gap_count > 0`; courtesy stub for clean cycles is the convention established by cnos#396, #401, #406–#427 close-outs and inherited by cnos#428).
