# β R1 review — cycle/428

**Issue:** [cnos#428](https://github.com/usurobor/cnos/issues/428).
**Surface under review:** α's replacement of `docs/gamma/essays/CELL-OF-CELLS.md` content (v0.1.0 → v0.2.0) per operator's verbatim seed in the issue body.

## Verdict

**R1: APPROVED.** All 11 ACs PASS per mechanical grep oracle (`self-coherence.md`).

## Per-AC rationale

- **AC1 — File replaced with v0.2.0.** Line count 741 (within 600–950); first line is the frontmatter delimiter `---`; H1 `# Cell of Cells` at line 29; H2 subtitle `## Recursive Coherence as a System Model` at line 31. Structural shell matches operator's seed. PASS.

- **AC2 — Frontmatter v0.2.0.** Exactly one `version: v0.2.0` line; exactly one `date: 2026-05-24` line; `related:` list carries 17 entries including the new `RECEIPT-VALIDATION.md` and `usurobor/tsc:spec/c-equiv.md` cross-repo reference. PASS.

- **AC3 — 19 ordered sections.** Grep finds exactly 19 top-level numbered H2 sections (`## 1.` … `## 19.`) in monotonic order. Section titles match operator's seed exactly. PASS.

- **AC4 — §16 sub-sections.** Six `### 16.x.` sub-sections present (Task / Issue / Receipt / Handoff / TSC / Persona memory). PASS.

- **AC5 — §18 sub-sections.** Six `### 18.x.` sub-sections present (Non-tree cells / Authority / Retraction / Public-scale / Persona hubs / Cycle-vs-cell). PASS.

- **AC6 — No mojibake.** The combined mojibake regex (`Î[±²³´µ]|â¡|matterâ|Cellâ|âµ`) returns 0 hits. Substitution table from cycle/414 applied cleanly across the entire content. PASS.

- **AC7 — Unicode density.** Greek-letter occurrences = 76 (target ≥ 30); subscript ₙ occurrences = 40 (target ≥ 5); ASCII-arrow `→` occurrences = 22 (target ≥ 10); `C≡` occurrences = 3 (target ≥ 1). Comfortably exceeds every floor. PASS.

- **AC8 — Composition law branches.** §8 pseudocode block lays out all three δ-decision branches explicitly: `PASS + accept/release`, `override` (degraded transmission), `repair_dispatch` (cell reopens), plus the residual transmit-failure case. Aggregate hit count = 7 across the document. PASS.

- **AC9 — §11 reframings.** All three CCNF-phrase reframings appear with arrows in §11: `"contractₙ is given"` → downward message; `"receiptₙ is emitted"` → upward return; `"generate next issue"` → parent-generated from measured incoherence. PASS.

- **AC10 — No other docs touched.** `git diff --name-only origin/main..HEAD -- docs/` returns exactly `docs/gamma/essays/CELL-OF-CELLS.md`. README pointer (which is version-agnostic) untouched. Five other gamma essays untouched. PASS.

- **AC11 — No code/schema/skill changes.** `git diff origin/main..HEAD -- src/ schemas/ scripts/ .github/` returns 0 lines. Refusal conditions held; the mode-pin (docs-only) held. PASS.

## Override / degraded transmission

**None.** δ has no override to record. The receipt crosses the cell wall as `accepted`, not `degraded`.

## β independence posture

This cycle ran as **β-α-collapse-on-δ** per the dispatch brief, which is the breadth-2026-05-12 wave-manifest precedent for skill/docs-class cycles where α=β collapse is permitted for mechanical work (docs cleanup) but not substantive code. The δ-pinned AC oracle is mechanical (grep + line count + file scope), which is the immunology firebreak that makes α=β collapse safe here: even if α's eye missed a substantive issue, the AC grid would surface it. No structural-independence-axis degradation arises because the oracle is the independent discriminator.
