# β-collapsed self-review — cycle/396

**Issue:** [cnos#396](https://github.com/usurobor/cnos/issues/396).
**Reviewer:** δ-as-agent (β-α-collapsed, γ+α+β-collapsed-on-δ; docs-only collapse acknowledged in δ's contract).
**Surface under review:** `src/packages/cnos.cdr/docs/empirical-anchor-cph.md`.

## AC verdicts (mechanical)

### AC1 — Document exists at canonical path: **PASS**

- `test -s src/packages/cnos.cdr/docs/empirical-anchor-cph.md` returns 0; file is 217+ lines.
- Path matches δ's pinned scoping (`src/packages/cnos.cdr/docs/empirical-anchor-cph.md`).
- Content is structured (sections §0–§6 with explicit §1 mapping table).

### AC2 — Every load-bearing cph artifact class is mapped: **PASS**

Issue body oracle (literal):

```
rg "PROJECT.md|CDR.md|ROADMAP.md|wave-manifest|wave-receipt|wave-closeout|field-report|dataset|diagnostic-oracle|gate.*verdict|hash.*pinning|cph#32" src/packages/cnos.cdr/docs/empirical-anchor-cph.md
```

Returns 49 total hits, with ≥1 hit per pattern:

| Pattern | Hits |
|---------|------|
| PROJECT.md | 5 |
| CDR.md | 30 |
| ROADMAP.md | 7 |
| wave-manifest | 1 |
| wave-receipt | 1 |
| wave-closeout | 5 |
| field-report | 3 |
| dataset | 3 |
| diagnostic-oracle | 1 |
| gate.*verdict | 3 |
| hash.*pinning | 2 |
| cph#32 | 7 |

All 12 issue-body classes covered. Additional row 12 (multi-agent attribution) and row 13 (cph#32) covered. Two survey-discovered extensions (rows 14, 15) also covered: coherence-log and intra-wave status tracking. **15 cph artifact classes mapped total**.

### AC3 — Zero "no cdr surface for this" rows: **PASS**

`rg "TBD|no surface|not mapped" src/packages/cnos.cdr/docs/empirical-anchor-cph.md` returns 1 hit:

- Line 201: `- No "no surface" rows; no TBD; no "not mapped" entries.`

This single hit is in **clear prose-context** per AC3's explicit allowance ("or only in clearly-prose-context where the doc explicitly discusses what's NOT a CDR surface concern"). The hit appears in §6.1 "Named gaps" as a **meta-statement** explicitly announcing that the §1 mapping table contains zero such rows. The §1 table itself was inspected row-by-row: every row has a concrete CDR.md section or schema field in the cnos.cdr v0.1 surface column.

Note: §4 is titled "Non-surface concerns" (hyphenated `non-surface`); this does not trigger the AC3 oracle (which matches `no surface` with a space). §4's content is the prose-context discussion of project-binding content that is **deliberately not** absorbed by CDR — also a prose-context allowance.

### AC4 — cnos#376 AC3 (empirical-anchor) satisfied: **PASS**

- Preamble §Scope: "Closes [cnos#376](https://github.com/usurobor/cnos/issues/376) AC3."
- §6 heading: "Closing — cnos#376 AC3 satisfied"
- §6 explicit close: "**cnos#376 AC3 is therefore satisfied** by this document at cph commit `2bf73ad64b7aa338cc6c8bc48067fbbba818cffa`."
- cnos#376 cited 4× in the doc; AC3 mentioned in conjunction at preamble, §6 heading, and §6 close.

The post-merge cnos#376 close-out comment (lifecycle step 9) will cite this doc, completing the AC4 oracle's full clause.

### AC5 — Read-only-source, no cph prose embedded: **PASS**

- 23 instances of the cph SHA pin (`@2bf73ad6` short form or full SHA).
- Citations carry `<cph-path>@<sha>` pattern throughout (verified by inspection of rows 1–15 in §1 and the verdict cross-walk in §2).
- Verbatim cph snippets present are all ≤1 line each, used as verdict-vocabulary anchors:
  - "GO with bounded scope (path (a) inferred bilateral)" (row 7 / §2)
  - "REVISE for friend pre-pilot" (§2)
  - "Construct survives R4 contact subject to anchor caveats" (§2)
  - "close Sub C as NO-GO with rationale per protocol" (§2)
  - "Partial GO on R-side" (§2)
  - "indeterminate on bilateral inferred-bilateral surface" (§2)
- Six blockquote lines (`^\s*>`) — all in §0's leading note about the doc's own structure and the citation of CDR.md's "Detailed mapping deferred to Sub 4" section. None reproduce cph-local prose paragraphs.
- The full SHA-256 dataset hash for OpenCap (64-char hex) appears once in row 11 — this is data (a hash), not cph-local prose, and is essential evidence that the hash-pinning practice is realised. AC5 explicitly permits "cph commit SHAs / file paths"; the dataset hash is analogous (a cryptographic pin published in cph as evidence).

## Findings

**No blocking findings.** All five ACs PASS.

### Non-blocking observations

1. **Extension rows.** §1 carries 15 rows (13 issue-body + 2 survey-discovered: coherence-log and intra-wave status tracking). Both extensions map onto existing cnos.cdr v0.1 surfaces (Field 5 and Field 4 respectively); no new CDR surface required. Per δ's refusal-condition guidance: "A cph artifact class exists that's not in the issue body's enumeration → extend the mapping table; note the addition" — observed and applied.

2. **cph CDR.md non-existence.** cph has no top-level `CDR.md` (HTTP 404 confirmed during survey). Row 2 of §1 maps this empirically observed structure ("project-local CDR doctrine") onto `CDR.md §"Empirical anchor"` and notes the post-uplift state (cnos.cdr owns the protocol-overlay doctrine; cph owns the project binding). This is not a gap or finding — it is the **expected** post-uplift architecture; the row records the empirical observation that the predecessor doctrinal file has been uplifted out of cph by the parent cycle (cnos#376) itself.

3. **Role-overlay references by name only.** Rows referencing `cnos.cdr/skills/cdr/{alpha,beta,gamma,delta,epsilon}/SKILL.md` (Sub 3 deliverables; cnos#395) are by name; the doc does not depend on their merge state per design-notes §"Frozen non-goals". This is the correct posture given Sub 3's potentially-deferred merge.

4. **cph commit pin.** SHA `2bf73ad64b7aa338cc6c8bc48067fbbba818cffa` is the head of cph `main` at filing time. Future cph waves may introduce artifact classes not surveyed; the §6.1 "Named gaps" subsection names this explicitly.

## Verdict

**APPROVE.** All five ACs PASS. No blocking findings. 15 cph artifact classes mapped (13 issue-body + 2 extensions); no "no surface" rows in the §1 table; cnos#376 AC3 closed via §6.

Proceed to close-out + merge.
