# α Closeout — Cycle #390

**Cycle:** [#390](https://github.com/usurobor/cnos/issues/390) — Sub 1 of [#376](https://github.com/usurobor/cnos/issues/376): CDR six-field instantiation contract + architecture-choice declaration
**Date:** 2026-05-21
**Branch:** `cycle/390`
**Implementation SHA:** `4eaa11443f8bf8a7efc59b6ed53bdb3d462e41aa`
**Base SHA:** `417b6227ba7ce7c47e02ec4e8b9614feb70b6f64`
**α identity:** alpha / alpha@cdd.cnos (γ+α+β-collapsed on δ, single Claude Code session)

---

## §Verdict (α-self-statement)

`src/packages/cnos.cdr/skills/cdr/CDR.md` lands. All six instantiation-contract fields declared per `ROLES.md §3`, each in research-loss-function language. Architectural-choice section records option (a) inheritance from cnos#388 with explicit (b)-rejected statement. Persona/protocol/project boundary section names all three layers with canonical homes. Empirical anchor cites cph by path with shape-compatibility claim; detailed mapping deferred to Sub 4 of #376.

All 6 ACs are mechanically verified (`rg` / `wc` / `grep` / classification sweep). The β-α-collapse is acknowledged in `beta-review.md`; β oracles are mechanical for docs-only contract authoring.

α signals review-readiness at SHA `4eaa1144`. β proceeded to APPROVE on R1.

## §Decisions

### D1 — Architectural inheritance recorded by reference, not re-derivation

The `## Architecture choice` section cites `schemas/cdd/README.md §"Architectural choice"` + cnos#388 for rationale (1)–(5); the section transposes the five points to skills with skill-specific examples but does not re-derive the underlying decision-class rationale. This honours cnos#388's rationale 5 ("decision-once-applied-twice") and prevents drift if the source rationale is later refined.

### D2 — Six-field language is research-loss-function, not engineering

Every field uses research-discipline vocabulary; engineering-discipline tokens (release, deploy, tag, CI, compile, tests-pass) appear only in disavowing contexts. Specifically:
- Field 1 routes software-evidence to CDS by reference, not authorship.
- Field 2 rejects "compiles + tests pass" by name.
- Field 4 disavows release/tag/deploy as the CDR δ verb.
- Field 5 trigger classes are entirely research-failure classes.
- Field 6 explicitly rejects engineering-class collapse precedent transfer.

### D3 — Empirical anchor cph cited path-only

cph paths are listed; cph's gate verbs are mapped onto doctrinal vocabulary as project-naming variants. No cph-local prose is embedded — the refusal-condition discipline is honoured.

### D4 — Field 4 cadence in wave-shape language

The δ cadence is stated in wave-shape language (wave open / in progress / close) tied to gate-transitions, not calendar/release-bundle cadence. The trigger taxonomy (NO-GO → follow-up; GO → synthesis; BOUNDED-GO → scope-expansion; INDETERMINATE → measurement-design) is research-protocol-shaped.

### D5 — Field 6 actor-collapse rule pins α=β never for research claims

The rule explicitly states no research-class waiver exists for the α=β collapse, and explicitly states engineering-class collapse precedents do not transfer. This is load-bearing: it prevents the same-session β-α-collapse pattern (which this cycle itself uses for docs-only contract authoring) from being misread as a research-class waiver template.

## §Findings Encountered

### F1 — α=β collapse for this cycle borderline against Field 6

α encountered this borderline while authoring Field 6: this cycle (#390) runs γ+α+β-collapsed on δ. Field 6 prohibits α=β for research claims. The cycle's matter is doctrinal contract authoring, not research-claim authoring; the cycle is structurally CDS-shaped (docs-only under repairable feedback). The reconciliation is named in `beta-review.md` Borderline observation. The cycle's class is correctly identified; Field 6's rule is honoured doctrinally because no `#CDRReceipt` is being authored here. Recorded for the record.

### F2 — Schema-side CDR gate-verdict vocabulary not pinned

The CDR gate-verdict vocabulary (GO / REVISE / NO-GO / INDETERMINATE / BOUNDED-GO) is declared at the doctrinal layer in Field 3 and mapped onto `schemas/cdd/boundary_decision.cue`'s typed surface (`action` enum + `transmissibility` enum). The schema does not pin a CDR-specific verdict enum. This is acceptable for Sub 1 (the typed surface remains the schema; the verdict names are operator-facing labels mapped to the typed surface). A future cycle may pin a CDR-specific verdict enum if cph or downstream research projects' gate verbs drift. Recorded as design-notes §OpenQuestions item 1; named in self-coherence §Debt item 4.

### F3 — `tag` token appears in non-release-tag sense in Field 5

`tag` appears in Field 5 in the sense of "tagged with one of the classes above" (label-tag for issue/finding classification), not release-tag. AC5's forbidden-token rule targets release/deploy/tag as δ-cadence verbs; the label-tag usage is distinct semantically. β classified the hit as non-violating. Recorded so a future ε pattern-match does not mis-flag.

## §Debt

(Same list as self-coherence.md §Debt; preserved here for the close-out record.)

1. `cnos.cdr` package metadata not authored — Sub 2 of #376.
2. Role-overlay skills not authored — Sub 3 of #376.
3. Empirical-anchor mapping not exhaustive — Sub 4 of #376.
4. CDR gate-verdict vocabulary not enum-pinned in `schemas/cdr/receipt.cue`.
5. Actor-collapse rule (Field 6) sets a doctrinal floor; project-specific stricter floor template not provided.

## §Skills-That-Helped

- `cdd/design` — design-half discipline; architectural-choice section structure followed from L7 design analysis.
- `cdd/issue/contract` — six-field section structure is contract-shaped (one section names one truth precisely).
- `cdd/issue/proof` — AC oracle authoring; each AC has mechanical oracle + line-numbered evidence.
- `cdd/post-release` §5.6b — closure-gate: `cdd-iteration.md` to be authored even if findings empty.
- Structural exemplars: `CDD.md` (heading shape for instantiation-contract authoring without copying software-protocol verbs); `schemas/cdd/README.md §"Architectural choice"` (decision-record format inherited).
