## §Cycle summary

Shipped 5 CDR role overlay SKILL.md files (`alpha/`, `beta/`, `gamma/`, `operator/`, `epsilon/`) under `src/packages/cnos.cdr/skills/cdr/` and a fully-merged loader at `cdr/SKILL.md`. Each role overlay extends the corresponding `cnos.cdd/skills/cdd/<role>/SKILL.md` engineering doctrine by inheriting the kernel grammar (role-cell shape, algorithm structure, independence rules, resumption protocol) and replacing only the discipline profile and matter type with research-loss-function content per `ROLES.md §4a.2` and `CDR.md` (Sub 1's contract).

AC1–AC6 PASS by mechanical oracle + classification tables (see `self-coherence.md §ACs` and `beta-review.md §Findings`).

The cycle/395 worktree paid one integration cost: cycle/394 (Sub 2 package skeleton) and cycle/396 (Sub 4 empirical-anchor doc) both merged to main between this cycle's branch-creation and merge. The Sub 2 loader at `cdr/SKILL.md` used `delta/SKILL.md` as the δ-role path, but δ's pinned implementation contract for Sub 3 specified `operator/SKILL.md` (mirroring the cnos.cdd exemplar). The rebase-time merge integrated Sub 2's richer loader content while correcting the path reference to `operator/SKILL.md`, which is consistent with Sub 3's role-overlay layout and with the cnos.cdd structural exemplar that CDR.md cites.

## §Close-out triage

| Finding | Source | Type | Disposition | Artifact / commit |
|---|---|---|---|---|
| F1 (α): AC oracle wording vs intent (recurring with #390) | α-closeout, β-review | cdd-protocol-gap (oracle-template friction) | next-MCA — same-class as #390 F1; pattern continues across Subs of #376 | ε iteration F1 |
| F2 (α): Sub 2 loader-file integration mechanical conflict | α-closeout | cdr-protocol-integration | landed-in-merge — the rebase-time loader integration resolved the path-naming inconsistency between Sub 2's `delta/SKILL.md` and Sub 3's pinned `operator/SKILL.md` | merge commit `f891f08b`; loader file now references `operator/SKILL.md` |
| F3 (α): Engineering-class β-α-collapse for docs-only protocol-document authoring validates further | α-closeout | positive pattern | drop — recorded as 6+-cycle precedent (375/377/378/388/390/395) | none |
| F4 (α): ε structural-role pattern reinforced across c-d-X family | α-closeout | positive pattern | drop — recorded | none |
| Obs-1 (β): AC oracle disavowal-context carve-out should be templated | β-review | cdd-protocol-gap candidate | next-MCA — accumulated 2 cycles' worth of evidence (#390 + #395); a third instance triggers MCA file | ε iteration F1 |
| Obs-2 (β): Sub 2 loader-file integration | β-review | landed-in-merge | landed-in-merge | merge commit `f891f08b` |
| Identity-on-rebased-commits (γ): rebase reset author email to "gamma" or "beta" for commits that were originally `alpha@cdd.cnos` | post-merge observation | cdd-skill-gap (α §2.6 row 14 path (b) debt) | drop — engineering-class single-session collapse cycle; identity is informational across collapsed roles; no research claim transmitted | none |

Silence is not triage. Every finding has a disposition.

## §9.1 trigger assessment (per `gamma/SKILL.md §2.8` table)

| Trigger | Fire condition | Fired? | γ note |
|---|---|---|---|
| Review churn | review rounds > 2 | **No** | R1 APPROVED on first pass. |
| Mechanical overload | mechanical ratio > 20% AND findings ≥ 10 | **No** | 4 α findings + 4 β observations; well below threshold. |
| Avoidable tooling / environment failure | environment blocked the cycle | **Partial** | Two surfaces:<br/>(a) `cd /home/user/cnos` overrode worktree cwd state during a setup command, requiring re-author and reset of the rogue main-worktree commit — single occurrence, recoverable, no protocol patch warranted.<br/>(b) Signing server (`environment-runner code-sign`) blocked merge attempts from `/tmp` paths and from non-canonical worktrees with `signing-server returned status 400: missing source`. Resolved by performing the merge from a named local branch (`merge-395`) within the cycle/395 worktree's git context, then `git push merge-395:main`. Recorded for ε; no protocol patch needed (the pattern is recognized — merge from a known worktree's git context, not from a fresh clone). |
| Loaded-skill miss | a loaded skill should have prevented a finding | **No** | F1 and Obs-1 are second-occurrence next-MCA candidates that the existing skills do not yet sharpen against; not a loaded-skill miss. |

No trigger fires that requires a Cycle Iteration entry to close. The cycle ran cleanly.

## §Cycle iteration

No formal trigger fired. The independent γ process-gap check (per `gamma/SKILL.md §2.9`) does identify one accumulating pattern across the cnos#376 sub-cycle family:

- **AC oracle disavowal-context carve-out should be templated.** Cycle #390 (Sub 1) surfaced the pattern for `release|deploy|tag` (6 hits in CDR.md, all in disavowal context, accepted via classification). Cycle #395 (this) surfaces the pattern for the same plus `I am Rho|my voice` (AC4) and `dispatch|polling` (AC6). The issue-template for protocol-overlay-authoring cycles should carve out "in disavowal context" or "in cross-reference to the parent doctrine being extended" as a structural exception to the literal-`rg` oracle. A third occurrence (likely in cnos.cdw or cnos.cda first-bootstrap cycles) will trigger the MCA. Recorded for ε; not patched this cycle.

## §Skill-gap candidate dispositions

Both surfaced patterns (F1 / Obs-1 the oracle-template friction; F2 the Sub 2 loader integration) are addressed:
- F1 / Obs-1 → ε iteration F1 (next-MCA on third occurrence; same-class continues).
- F2 → landed in merge commit `f891f08b` (loader path corrected to `operator/SKILL.md`).
- F3 / F4 → positive patterns; drop with explicit attribution.

## §Deferred outputs

- **Cycle-dir move.** `.cdd/unreleased/395/` → `.cdd/releases/<version>/395/` at next release per `release/SKILL.md §2.5a`. Standard release-time mechanic. Not blocking.
- **Lifecycle sub-skills** (`issue/`, `design/`, `plan/`, `review/`, `release/`, `post-release/` for CDR) — deferred to cds emergence per issue Non-goals. Recorded.
- **Project-specific stricter-floor template** — same-class debt as #390 F2. Defer to Sub 4's cph mapping or to a later cnos.cdr cycle.
- **Wave-coordination primitive for research γ** — engineering γ §10 has wave-coordination; research γ analogue not authored. Defer to Sub 4 (which already shipped — re-evaluate against Sub 4's content) or to a later cycle.

## §Hub memory evidence

This cycle does not surface a finding requiring agent-hub memory update. Pattern-level findings (F1 / Obs-1, the oracle-template carve-out) flow into ε's iteration index, not into a hub note. The role-overlay surfaces are now available for any actor playing a CDR role; future cycles binding CDR (e.g. when cph runs a research wave under CDR) load these files directly.

## §Post-merge CI verification

The cnos repo's CI exercises Go test suites and skill-frontmatter validators. This cycle's diff is Markdown-only (5 SKILL.md role overlays + 1 loader integration + cycle artifacts under `.cdd/unreleased/395/`). No Go code or schemas were modified; no test surface touched. Skill-frontmatter validators (if run as part of CI on the merge tree) would verify each new SKILL.md file's YAML frontmatter parses; α and β both manually verified frontmatter integrity in `self-coherence.md` and `beta-review.md`. Post-merge CI status: not blocking on this cycle.

## §Next MCA

cnos#376 master has now shipped:
- Sub 1 (#390, CDR.md contract) — complete
- Sub 2 (#394, package skeleton) — complete (shipped before this Sub)
- Sub 3 (#395, role overlays) — **this cycle, complete**
- Sub 4 (#396, empirical-anchor doc) — complete (shipped before this Sub)

The cnos#376 master close-out comment can now confirm all four Subs have landed. The CDR protocol overlay (`cnos.cdr` v0.1) is operationally complete at the protocol layer; lifecycle sub-skills (`issue/`, `design/`, `plan/`, …) are deferred to cds emergence as documented in `CDR.md` and `cnos#395` Non-goals.

Cycle #395 closed. cnos#376 closes when γ posts the master close-out comment.
