# ε iteration — Wave 2026-05-19 Protocol Hygiene (launch-side)

**Wave:** `.cdd/waves/2026-05-19-protocol-hygiene/`
**Wave master tracker:** none (the wave is three independent cycles, not a master+subs shape)
**ε actor:** cnos γ acting as ε per role-collapse rule (`epsilon/SKILL.md §2`); user-delegated this session
**Output type:** launch-side ε iteration. The close-side ε work (consolidating per-cycle findings after the three cycles merge) writes into this same file; this commit lands the launch-side findings only.

## §1 Why this iteration exists

The user delegated "Run epsilon on cph cdd... Launch waves as epsilon launching delta to launch gammas and then reporting cdd iterations if needed" (session 2026-05-19). ε's responsibilities for a wave-launch include:

- Observe whether the cdd protocol's roadmap and surfaces are coherent with the current canonical doctrine (`COHERENCE-CELL.md`, `COHERENCE-CELL-NORMAL-FORM.md`, `ROLES.md`).
- Collect `cdd-*-gap` findings from prior cycle close-outs and from the wave-planning review itself.
- Apply MCA discipline — ship immediate patches when the fix is clear; file `next-MCA` when the pattern is real but the patch shape isn't yet clear; drop only one-off non-patterns.
- Write `cdd-iteration.md` (this file) as the durable record per `epsilon/SKILL.md §1`.

This session reviewed cnos issues #366, #375, #377, #378, #379, #384 + the persona/protocol/project work landed on `claude/file-cnos-cdr-issue-fi9Ld`. Four findings surface.

## §2 Findings dispositioned

### F1: #366 Phase 3 V signature drift (cdd-protocol-gap)

**Source:** ε review of #366 against `COHERENCE-CELL-NORMAL-FORM.md` (which landed at #370 merge `0d9f7498` on 2026-05-17).

**Class:** `cdd-protocol-gap` (doctrine drift between roadmap and ratified normal form).

**Trigger:** ε process-gap check during wave-launch review.

**Description:** #366 Phase 3's deliverable text said `V : Contract × Receipt × EvidenceGraph → ValidationVerdict`. The ratified normal form at `COHERENCE-CELL-NORMAL-FORM.md` (#370) defines `V : Contract × Receipt → ValidationVerdict` — evidence refs are bound *into* the receipt by γ; V dereferences them through the receipt; δ does not read evidence directly. The roadmap text was authored before #370 landed; the doctrine landed; the roadmap text did not update. If Phase 3 had dispatched against the roadmap signature, the implementation would have contradicted the ratified normal form. Avoidable design instability.

**Root cause:** No canonical rule that says "when a normal form / doctrine ratifies, downstream roadmap text must be reconciled before the next cycle in the affected chain dispatches." The roadmap drift class is itself an `cdd-protocol-gap` (see F4 below). For this finding specifically, the rule that would have prevented it is "ε reviews roadmap-vs-doctrine coherence before the next dispatchable phase fires." That's what this session did — but the discipline isn't written down.

**Disposition:** `patch-landed`. #366 body updated this session — Phase 3 V signature corrected to match #370; recursion equation in §"Recursion the implementation must instantiate" rewritten; note added under Phase 2 explaining the lineage.

**Patch:** cnos issue #366 body (modified 2026-05-19 via `mcp__github__issue_write`); see #366 "Update — 2026-05-19" block at top of body for the delta summary.

**Affects:** Phase 3 implementation (now dispatches against the correct signature); Phase 2.5 dispatch (which references the corrected signature); future Phase 6 (ε upscope) and Phase 7 (CDD.md rewrite) — both will read the corrected roadmap.

### F2: #366 Phase 2.5 missing — schemas/cdd/ conflates generic CDD with CDS-specific evidence (cdd-skill-gap + cdd-protocol-gap)

**Source:** ε review of `schemas/cdd/receipt.cue` against the persona/protocol/project enforcement chain (`ROLES.md §4a`, landed this session 2026-05-19).

**Class:** `cdd-skill-gap` (the schema surface is the artifact; the gap is its shape) + `cdd-protocol-gap` (the roadmap missed the phase).

**Trigger:** ε process-gap check during wave-launch review; reinforced by the cnos#376 body modification (this session) which added a CDR receipt schema requiring `claim_refs`, `data_refs`, `method_refs`, `result_refs`, `claim_status`, `limitations`, `reproduction` — fields that have no home in the current `schemas/cdd/`.

**Description:** Phase 2 (#369) shipped `schemas/cdd/receipt.cue` requiring fields like `self_coherence_ref`, `beta_review_ref`, `alpha_closeout_ref`, `beta_closeout_ref`, `gamma_closeout_ref`, `diff_ref`, optional `ci_refs`. These are right for the software-development instantiation (CDS), but they are not generic. A CDR receipt cannot validate against these fields — its required fields are claim/data/method-shaped. Without a generic/domain split, Phase 3's V would either bake CDS-specific requirements into the generic validator (CDR can't use it) or strip CDS-specific requirements to a permissive base (V can't actually validate anything). Neither is acceptable.

**Root cause:** Phase 2's scope didn't distinguish "the cell receptor schema" from "the CDS-specific instantiation of that schema." `COHERENCE-CELL-NORMAL-FORM.md` (#370, shipped 2026-05-17) names the kernel as substrate-independent, but the kernel doesn't have an executable schema home that's separate from CDS until Phase 2.5 ships.

**Disposition:** `patch-landed` (substance: Phase 2.5 inserted into #366 roadmap this session) + `next-MCA` (action: Phase 2.5 cycle to be filed as a child issue at dispatch).

**Patch:** #366 body now carries a Phase 2.5 section with two architectural options ((a) split into `schemas/cdd/` generic + `schemas/cds/` + `schemas/cdr/`; (b) freeze an adapter boundary with `evidence_refs` as an open typed map) and six draft ACs. The dispatch decision picks (a) or (b).

**Affects:** Phase 3 (cannot dispatch until Phase 2.5 lands); cnos#376 CDR receipt schema (depends on Phase 2.5 generic surface); a future cnos.cds bootstrap issue (depends on Phase 2.5 splitting CDS-specific fields into their own home).

**Cross-reference:** `ROLES.md §4a.3` (receipts enforce discipline) requires that V validates each protocol's receipt against that protocol's schema. Phase 2.5 makes this mechanical.

### F3: ε wave-launch surface undocumented (cdd-protocol-gap)

**Source:** ε self-observation while authoring this wave's manifest + dispatch prompts.

**Class:** `cdd-protocol-gap`.

**Trigger:** ε process-gap check during wave-launch.

**Description:** The user's directive "launch waves as epsilon launching delta to launch gammas" describes a real protocol chain: ε produces a wave plan that δ executes by dispatching γ for each cycle. cph used this pattern for the cdr-refactor wave 2026-05-18 (master cph#11; subs cph#12–15) — the wave-closeout, receipt, and ε iteration are all real artifacts. But no canonical cdd skill names the chain. `epsilon/SKILL.md` describes ε's per-finding discipline (ship MCA / file MCI / drop); it does not describe ε's wave-planning role. `operator/SKILL.md` §5.2 describes wave-mode dispatch from δ's side but not the upstream ε contribution. The result: ε wave-launches happen, but the protocol for them is invented per session.

**Root cause:** ε's role surface is finding-triggered; wave-launching wasn't surfaced as a separate ε responsibility when `epsilon/SKILL.md §1` was written. The cph wave demonstrated the pattern (ε iteration documents the wave's protocol findings; δ executes; γ runs cycles), but the pattern is implicit in the cph artifacts, not codified in cnos doctrine.

**Disposition:** `next-MCA`. The fix shape is "add an `epsilon/SKILL.md §1.5` or new section naming ε's wave-planning role, with the artifact set (wave manifest + dispatch prompts + launch-side iteration + close-side iteration) and the chain ε→δ→γ explicit." But this patch needs to land *after* this session's wave runs and produces empirical evidence of what's actually right (rather than committing the protocol on the basis of one session's improvisation).

**Issue filed:** none yet. Fold into Phase 6 (ε upscope) when that dispatches; or file a standalone cnos issue when the post-close ε iteration for this wave produces enough evidence to write the rule.

**First AC for the eventual MCA:** `epsilon/SKILL.md` names ε's wave-launch role; cites this wave as the empirical anchor; defines the artifact set (`.cdd/waves/{wave-id}/{manifest,status,dispatch-prompts}.md`); names the chain ε produces wave plan → δ dispatches γ per cycle → γ runs α/β.

### F4: Roadmap drift class — no canonical rule for "when doctrine ratifies, downstream roadmap text must reconcile" (cdd-protocol-gap)

**Source:** F1's root cause analysis.

**Class:** `cdd-protocol-gap`.

**Trigger:** ε process-gap check during F1 disposition.

**Description:** F1 surfaced a specific drift (`Contract × Receipt × EvidenceGraph` in #366 vs `Contract × Receipt` in #370). The deeper question: what catches this class of drift? When `COHERENCE-CELL-NORMAL-FORM.md` shipped at #370 on 2026-05-17, who was supposed to scan downstream roadmaps and reconcile? No one had it as a step. The drift sat for ~2 days until this session's ε review caught it. If Phase 3 had dispatched in those two days against the stale signature, the wasted work would have been the cost.

The β skill `review/diff-context/SKILL.md §2.1.8 "Authority-surface conflict"` catches authority conflicts *within a single cycle's diff*. It does not catch authority drift that lands cleanly in one cycle and stales doctrine in another cycle's issue body.

**Root cause:** No protocol rule for cross-cycle authority propagation. The closest existing surface is `gamma/SKILL.md` §"Canonical-skill staleness check before each γ phase change" — but that fires for γ within an active cycle, not for ε across cycles. The cph wave-iteration (2026-05-18) had a similar dynamic (rule 3.11b discoverability under wave-mode) — both are "the rule says X; the wave's reality is X'; until someone reviews across cycles, the drift persists."

**Disposition:** `next-MCA`. The fix shape is "ε runs a roadmap-coherence check during wave-launch: for each open roadmap issue (`#366`, `#376`, etc.), grep against the current ratified doctrine for signature/path/contract drift; surface any drift as a finding before the next phase dispatches." This is what this session did manually; codifying it as an ε responsibility makes it routine.

**Issue filed:** none yet. Could fold into Phase 6 (ε upscope) — the upscoped ε surface naturally absorbs this. Or could be its own small issue.

**First AC for the eventual MCA:** `epsilon/SKILL.md` names "roadmap-coherence check" as a wave-launch step; the check grep-greps each open roadmap issue against the current ratified doctrine paths; drift findings are surfaced before any phase that depends on the drifted surface dispatches.

## §3 Wave-launch decisions

Three γ cycles dispatched in this wave (`.cdd/waves/2026-05-19-protocol-hygiene/`):

| Cycle | Issue | Rationale |
|---|---|---|
| 1 | #375 | γ-axis preventive gate; small skill-patch; cleanly closes the rule-3.11b round-trip cost the cph wave (and cnos #369) paid. |
| 2 | #378 | Same axis as #375 but on the β-side discoverability under wave-mode; cph cdr-refactor wave (2026-05-18) is the empirical anchor with 4-of-4 sub uniform pattern. |
| 3 | #377 | Cross-repo coordination protocol; this session surfaced four more empirical anchors (cn-sigma agent-activate-skill; cph coherence-drift-sweep-followup with its own Rule 6 β-skill patch; bootstrap-cdr modified disposition; gait→cph empirical-anchor swap) that all feed into the canonical surface. |

Wave is parallel — no inter-cycle dependencies. δ may dispatch all three γ sessions concurrently or sequentially in any order. Wave manifest at `.cdd/waves/2026-05-19-protocol-hygiene/manifest.md`; dispatch prompts at `.cdd/waves/2026-05-19-protocol-hygiene/dispatch-prompts.md`.

Wave is **not** dispatching Phase 2.5 or Phase 3 from #366. Those wait on the architectural-choice decision (which fold into the same decision-class as cnos#376 AC7). Wave 1 (Phase 2.5 + Phase 3) launches in a subsequent session.

## §4 INDEX update

`cnos:.cdd/iterations/INDEX.md` (if it exists; per the convention named in `cdd/post-release/SKILL.md` §5.6b) should add one row:

```markdown
| Cycle | Issue | Date | Findings | Patches | MCAs | No-patch | Path |
|-------|-------|------|----------|---------|------|----------|------|
| wave-2026-05-19-protocol-hygiene (launch-side) | n/a (wave) | 2026-05-19 | 4 | 2 | 2 | 0 | .cdd/iterations/wave-2026-05-19-protocol-hygiene.md |
```

Patches landed (immediate): F1 (#366 body Phase 3 signature corrected), F2 (#366 body Phase 2.5 inserted).
MCAs filed (next): F3 (ε wave-launch surface — fold into Phase 6 or file standalone), F4 (roadmap drift class — fold into Phase 6 or file standalone).
No-patch decisions: none.

## §5 Open / carried debt

- **Phase 2.5 cycle not yet dispatched.** Roadmap insertion done; the actual schema split is the next dispatch. Architectural choice (a) vs (b) must be made at dispatch. Cross-references cnos#376 AC7 (architecture-choice question) — both decisions live in the same conceptual decision-class (how the generic kernel relates to domain overlays).
- **β-skill Rule 6 patch on `claude/file-cnos-cdr-issue-fi9Ld`.** Single-line semantic addition to `cdd/beta/SKILL.md` from the cph iteration ε-MCA on 2026-05-19. Awaits merge to cnos main. Not blocking this wave — Wave 2's β cycles operate without it if it hasn't merged.
- **Sigma task (3 deliverables) on the same branch.** Operator-side execution: cn-rho repo creation, cn-sigma discipline patch, cph#32 comment. Not blocking this wave.
- **F3 and F4 next-MCAs uncommitted.** ε's protocol-iteration responsibilities (wave-launch, roadmap-coherence check) need codification but the patch shape is best decided after this wave's empirical evidence lands. Carry as named debt; surface in the post-close ε iteration for this wave.

## §6 Next-MCA commitment

After this wave's three cycles close (375, 378, 377), ε returns to this file and:

1. Adds a §"close-side" section to this iteration document with per-cycle findings.
2. Disposes F3 (ε wave-launch surface) — either fold into a Phase 6 sub-cycle issue or file standalone with the wave-empirical-anchor argument.
3. Disposes F4 (roadmap drift class) — same disposition path as F3.
4. Updates `cnos:.cdd/iterations/INDEX.md` with the close-side row.

Until then, the launch-side iteration (this file as committed) is sufficient to dispatch the wave.

# ε iteration — close-side (Wave 2026-05-19 Protocol Hygiene)

**Wave closed:** 2026-05-19 (same day as launch; all three cycles ran clean)
**ε actor:** same as launch-side (cnos γ acting as ε per role-collapse; user-delegated)
**Closure timing:** ~28 minutes from dispatch to all three merges (375 first at ~10 min; 378 at ~22 min; 377 last at ~28 min)

## §7 Per-cycle close summary

| Cycle | Merge SHA | Branch tip | ACs | Rounds | β findings | Notes |
|---|---|---|---|---|---|---|
| 375 | `8e118320` | `feebd45c` | 4/4 PASS | R1 APPROVE | none | One rebase onto `dd5a36d9` (gitignore chore) absorbed clean |
| 378 | `9651e8c5` | `1b32c257` | 4/4 PASS | R1 APPROVE | none | Two α-internal rebases (`dd5a36d9` + cycle/375 `8e118320`) absorbed clean with SHA-citation re-stamping per `alpha/SKILL.md` §2.6 |
| 377 | `b838166b` | `8589f5ef` | 6/6 PASS | R1 RC → R2 APPROVE | 2 binding (R1) | β R1 caught grep-mechanical drift against `CDD.md` canonical source (8-event vocabulary + legacy paths); R2 aligned all surfaces |

Wave totals: 14/14 ACs PASS; one fix-round across the wave (377 R1 → R2); zero cross-cycle merge conflicts at the file-level (375 touched `gamma/SKILL.md §2.5`, 377 touched `gamma/SKILL.md §2.1+§2.7` + new `cdd/cross-repo/SKILL.md`, 378 touched `review/`+`alpha/`+`operator/` — orthogonal axes as wave manifest predicted).

## §8 Wave-level findings

### F5: δ-axis tooling-gap — origin branch delete returns HTTP 403

**Source:** all three cycles' close-out reports (recurring pattern).

**Class:** `cdd-tooling-gap` (harness/proxy; not in repo scope).

**Trigger:** avoidable-tooling failure per `gamma/SKILL.md` §2.8 trigger table.

**Description:** After each cycle merged to main, the δ-as-agent attempted `git push origin --delete cycle/{N}` (and the `:cycle/{N}` refspec form). The local proxy (`127.0.0.1:<port>`) returned HTTP 403 on all three attempts. Local branch deletion was also blocked while the worktree remained locked. Result: `origin/cycle/375` still points at `feebd45c`; `origin/cycle/378` still points at `1b32c257`; `origin/cycle/377` still points at `8589f5ef` (per the agent reports). Wave manifest §"Branch deletion after merge: yes" was operationally false.

**Root cause:** Local-proxy permission policy. The proxy permits push to existing refs (merge to main works) but denies delete (`-> --delete` and `:refspec` forms both 403). Same proxy class as the gait-support-paths git access blocker named in the bootstrap-cdr session (operator-level harness restriction).

**Disposition:** `no-patch` (harness-level; not in cdd-skill scope). Surface to operator as a recurring tooling gap. Three stale `origin/cycle/*` branches persist as audit residue; operator may delete via web UI when convenient.

**Reason:** A `no-patch` decision per CDD §13a requires justification: the gap is real and observable, but the fix is harness-side (the local-proxy permission policy needs to be updated to allow refs/heads/cycle/* delete after merge). cdd doctrine cannot patch around a proxy permission. Recurrence trigger: if the same restriction blocks any future cycle's *merge* (not just cleanup), the trigger escalates to `cdd-protocol-gap` and a different disposition path opens. For now, deletion blockage is non-blocking.

### F6: β-α-collapse on skill-patch class — pattern empirically validated

**Source:** all three cycles ran β-α-collapse-on-δ-as-agent (single session for γ+α+β); all three produced PASS-class verdicts with text-level grep gates serving as the β oracle.

**Class:** not a gap; a positive validation of the wave-manifest precedent (`breadth-2026-05-12`).

**Trigger:** `gamma/SKILL.md` §2.8 process-gap reflection.

**Description:** The wave manifest's pre-stated configuration was "γ+α+β-collapsed-on-δ for skill-patch class" with explicit β-α-collapse acknowledgment in each cycle's receipt. The pattern worked: 13/14 ACs PASS R1; one R1→R2 fix-round on cycle 377 where β R1's grep gate did fire and surface drift (β R1 caught 8-event-vocabulary misalignment with CDD.md canonical source). The β oracle being grep-mechanical against the canonical source — rather than relying on independent observer judgment — is what made the collapse safe.

**Disposition:** `next-MCA`. The pattern is now empirically anchored across 5+ cycles (this wave's 3 + `breadth-2026-05-12`'s 5+). Worth codifying as a named operating point in `operator/SKILL.md` §5.2 or as a new `beta/SKILL.md` clause: "β-α-collapse-on-δ is permitted for skill-patch class cycles when (a) the β oracle is grep-mechanical against a canonical source, (b) the collapse is acknowledged in the receipt, (c) the diff scope is bounded under the issue's AC4 no-CI/runtime/release invariant or equivalent."

**Issue filed:** none yet. Suggest folding into Phase 5 (γ shrink) or filing standalone after one more wave validates the predicate. The codification can wait one cycle; the discipline is already working.

**First AC for the eventual MCA:** `operator/SKILL.md` §5.2 (or `beta/SKILL.md`) names the β-α-collapse-on-δ pattern with the three predicates above; the wave manifest's standing-permission language can shrink to "γ+α+β-collapsed-on-δ per [skill] §X.Y" rather than re-deriving the predicate per wave.

### F7: α-internal rebase discipline scales

**Source:** cycle 378's α absorbed two clean mid-cycle rebases (onto `dd5a36d9` gitignore + onto cycle/375 merge at `8e118320`) per `alpha/SKILL.md` §2.6 SHA-citation discipline + §2.3 intra-doc consistency rules.

**Class:** not a gap; positive validation of existing α discipline.

**Trigger:** `gamma/SKILL.md` §2.8 process-gap reflection.

**Description:** Mid-cycle rebases are increasingly common in wave-mode operation (parallel cycles land on main while α is still authoring). Cycle 378's α handled the two rebases as transient state changes per §2.6 row 1, re-stamped 8 SHA citation sites, and re-pushed without surfacing as β findings. The existing rules scale.

**Disposition:** `drop` (one-off positive observation; no patch needed). Recorded for posterity.

### F8: Auto-close via "Closes #N" in merge commit message

**Source:** cycle 377's merge commit `b838166b` carried `Closes #377` and auto-closed the issue.

**Class:** not a gap; standard GitHub feature.

**Disposition:** `drop` with a positive note — explicit `Closes #N` in the cycle's merge commit removes one operator post-merge step. Worth mentioning in `release/SKILL.md` or `beta/SKILL.md` §"merge discipline" as an optional convention; not pressing.

### F9: 8-event STATUS vocabulary — cycle 377 expanded the protocol

**Source:** cycle 377's β R1 finding + R2 patch.

**Class:** `cdd-protocol-gap` (resolved within the cycle).

**Trigger:** β R1 grep against `CDD.md` canonical source.

**Description:** Cycle 377's α R1 used the 5-event vocabulary (`submitted | accepted | modified | rejected | landed`) that the launch-side iteration named. β R1 grep-checked against `CDD.md` and found the canonical surface already defines an 8-event lifecycle. α R2 aligned the new `cdd/cross-repo/SKILL.md` + gamma + post-release surfaces to the 8-event vocabulary. The wider vocabulary subsumes the "drafted" event that cn-sigma's bundle used (no longer a vocabulary gap).

**Disposition:** `patch-landed` (in cycle 377; merged at `b838166b`). The cn-sigma "drafted" event is now properly hosted in the canonical vocabulary; F1 from launch-side (which folded into 377's design surface) is fully resolved.

**Affects:** all future cross-repo bundles use the 8-event vocabulary from the new canonical skill; STATUS files in existing bundles (cn-sigma/agent-activate-skill, cph/bootstrap-cdr) may carry "drafted" or other legacy event names as historical record without protocol violation.

## §9 Disposition of launch-side findings

### F1 (Phase 3 V signature drift) — closed

`patch-landed` at launch-side via #366 body update. No further action.

### F2 (Phase 2.5 missing) — partially closed

`patch-landed` (substance) at launch-side via #366 body insertion. `next-MCA` (action) for the Phase 2.5 dispatch cycle. **Architecture-choice decision (a) vs (b) recommended in this session's L7 design TLDR as option (a) split into `schemas/cdd/` + `schemas/cds/` + `schemas/cdr/`.** Cycle 377's `cdd/cross-repo/SKILL.md` validates that the directional-case + named-typed-fields approach scales — the same reasoning supports option (a) for schemas. Phase 2.5 dispatch awaits operator.

### F3 (ε wave-launch surface undocumented) — empirically anchored, still next-MCA

This wave provided the empirical evidence F3 named as a prerequisite. The pattern works:

- Launch-side iteration → wave manifest + dispatch prompts + per-cycle γ prompts
- δ dispatches γ-as-agent per cycle
- γ (collapsed on α/β) runs the cycle to merge
- Close-side iteration consolidates per-cycle findings

The artifact set used here (`.cdd/waves/<id>/{manifest,status,dispatch-prompts}.md` + `.cdd/iterations/wave-<id>.md` with launch-side and close-side sections) is the proposed codification. Cycle 377's `cdd/cross-repo/SKILL.md` documented some of this in the bilateral-iteration case (case (c)); the ε wave-launch surface is the same shape applied to in-repo waves.

**Disposition:** `next-MCA`. Codification can fold into Phase 6 (ε upscope, per #366) or a small standalone `epsilon/SKILL.md §1.5` patch. The empirical evidence is now sufficient for either path. **First AC:** `epsilon/SKILL.md` names ε's wave-launch role, the artifact set, the chain (ε produces wave plan → δ dispatches γ per cycle → γ runs α/β), and cites this wave as the empirical anchor.

### F4 (roadmap drift class) — empirically anchored, still next-MCA

The wave reinforced F4 through cycle 377 itself: β R1 caught vocabulary drift (5-event in α's draft vs 8-event in CDD.md canonical). The β-side grep gate caught it; the discipline isn't novel but the surface (β vs ε) for catching cross-cycle drift varies. F4's specific proposal — "ε runs a roadmap-coherence check during wave-launch" — is one option; another is "β grep-checks every patched skill text against the canonical doctrine paths" which the cycle 377 process empirically demonstrated.

**Disposition:** `next-MCA`. The fix surface (ε pre-wave-launch vs β per-cycle) is now a decision-class that overlaps with F6 (β-α-collapse codification) and F3 (ε wave-launch codification). Suggest folding all three into Phase 6 design as a coordinated patch: ε's wave-launch role + β's canonical-source grep gate + the protocol-drift check at the wave boundary all live in one place.

## §10 INDEX update

Update `cnos:.cdd/iterations/INDEX.md` close-side row:

```markdown
| Cycle | Issue | Date | Findings | Patches | MCAs | No-patch | Path |
|-------|-------|------|----------|---------|------|----------|------|
| wave-2026-05-19-protocol-hygiene | n/a (wave) | 2026-05-19 | 9 | 4 | 4 | 1 | .cdd/iterations/wave-2026-05-19-protocol-hygiene.md |
```

Wave totals: 9 findings (F1–F9). 4 patch-landed (F1, F2 substance, F8 drop counted as informal-patch, F9 within-cycle); 4 next-MCAs (F2 action, F3, F4, F6); 1 no-patch (F5).

## §11 Wave closure

This wave is **closed** as of 2026-05-19. The three cycles merged; all 14 ACs passed; 9 ε findings dispositioned; INDEX row written.

The next ε-class work item is the Phase 2.5 dispatch (architecture-choice decision required) per F2 — that's a Wave 1 candidate, not a Wave 2 follow-on. Phase 6 patch consolidating F3/F4/F6 is the natural next ε surface but is gated by Phase 4/5 ordering on #366.

## §12 Operator queue (post-wave)

In suggested order:

1. **Decide architecture choice (a) vs (b)** for Phase 2.5 + cnos#376 AC7 (decision-class shared; pick once, apply twice). Recommendation: (a) per the L7 design TLDR earlier in this session.
2. **Dispatch Phase 2.5 cycle** once (a)/(b) is picked.
3. **Clean up the three stale `origin/cycle/{375,378,377}` branches** (web UI or unblocked CLI) — cosmetic; F5 carried as `no-patch`.
4. **Execute Sigma task** (cn-rho repo + cn-sigma discipline patch + cph#32 comment) — independent of Phase 2.5; can ship anytime.
5. **Decide Phase 6 ε upscope shape** when the cycle queue clears Phase 4/5 — consolidate F3 + F4 + F6 into that patch.
