# ε cdd-iteration — cycle/424

**Issue:** [cnos#424](https://github.com/usurobor/cnos/issues/424) — Add foundational design essay `CELL-OF-CELLS.md` to `docs/gamma/essays/` (recursive coherence-cell system model).
**Mode:** docs-only; γ+α+β-collapsed-on-δ. Per ε hygiene, empty findings are recorded explicitly.

## Findings

**None.**

This was a docs-only cycle producing exactly 2 file changes — one new essay (`docs/gamma/essays/CELL-OF-CELLS.md`, 657 lines) and one README update (`docs/gamma/essays/README.md`, 2 lines added). 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-collapsed-on-δ explicitly), no protocol-shape disagreement, no out-of-band coordination friction. The δ-pinned implementation contract was complete and unambiguous; α executed within it; β confirmed conformance.

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

**None surfaced this cycle.** Three non-binding observations from R1 review are recorded as positive forward-looking notes, not protocol-gap signals:

1. **Numeric-prefix section-heading discipline.** An early draft of CELL-OF-CELLS.md used numeric prefixes on `## ` section headings (`## 1. Problem:`, `## 2. Cell as recursive type`, etc.). The AC2 mechanical oracle expects unnumbered headings (`^## (Problem|Cell as recursive type|...)`), so the prefixes would have grep-failed AC2 if not stripped. α caught the mismatch during self-coherence and stripped the prefixes pre-commit. This is the same convention DECREASING-INCOHERENCE.md uses (unnumbered `## ` headings). Not a gap — caught and resolved at self-coherence. A future ε cycle could consider whether dispatch briefs for essay cycles should explicitly note "no numeric prefixes on top-level headings" as a defensive directive, but this is the kind of micro-discipline that the mechanical AC oracles already enforce and the precedent essays already model. Positive forward observation.

2. **Reading Order position justification convention.** The dispatch brief offered a choice between Reading Order position 1 and position 6 and required the agent to document the choice in `gamma-closeout.md`. The choice (position 6, last) was made and documented with three structural reasons (dependency direction; integration argument; foundational-claim-is-alpha-located). The convention of *requiring* a documented choice between operator-offered alternatives is a useful ε practice — it surfaces the design decision in the receipt-stream rather than hiding it in the agent's reasoning. Positive observation; no gap.

3. **β-independence collapse posture.** This cycle ran as `γ+α+β-collapsed-on-δ`. Per `COHERENCE-CELL.md §β Independence as Contagion Firebreak`, this collapses β's structural independence; the receipt is closed-as-degraded at the structural-independence axis. β-closeout.md names the collapse explicitly rather than papering over it, and offers the justification (docs-only + mechanical ACs + cycle-414 precedent + dispatch authorization). The discipline of *naming* the collapse rather than hiding it is good ε hygiene. A future cycle that operationalizes V as the cell-wall validator may re-run essays through an independent β-actor for confirmation; until then, the receipt carries the collapse as a known disposition. Positive observation; no gap.

None of these rise to a `cdd-skill-gap`, `cdd-protocol-gap`, `cdd-tooling-gap`, or `cdd-metric-gap` finding for this cycle. They are forward-looking notes for future ε signal aggregation.

## Non-findings (worth recording)

- **Operator seed was the substantive source.** The dispatch brief provided the operator's seed content verbatim and instructed α to "preserve all 15 sections, all equations, all worked examples, all named relationships, and all 'key corrections.' Tighten language for essay-class flow but do NOT discard substance." α held to this: the five-step interior block is verbatim; the three worked-example code blocks are verbatim; the three key-correction reframings appear with the exact before-after arrows from the seed; the strongest-statement quote is verbatim. Essay-class polish was added only to the surrounding prose (paragraph transitions, expository scaffolding, the table mapping in §Relation to TSC).

- **No protocol prescription.** The essay describes what cnos IS, not what it should become next. The tense is descriptive throughout. The Open Questions section explicitly preserves design space rather than closing it. The Hard Rule against protocol evolution held.

- **No #405 dispatch language.** References to CCNF-O / TSC roadmap appear in §11 (handoff's peer) and §15 (open question 5) as forward context, not direction. The essay informs CCNF-O without authoring or dispatching it.

- **Companion-essay coherence held.** The cell-of-cells thesis cites the prior gamma essays (`CCNF-AND-TYPED-TRUST.md`, `DECREASING-INCOHERENCE.md`) in §6, §9, §12, §13, §14 as the dependencies that justify Reading Order position 6. The prior essays themselves are unmodified — back-link insertion is explicitly forbidden by the dispatch's Hard Rule 4 and is deferred to a future cycle if desired.

## 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 `post-release/SKILL.md §5.6b` 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–#423 close-outs and inherited by cnos#424).
