+# B-0749 — KubeVela + OAM as standard vocabulary for ontology negotiation + reference-stack composition layer
+
+## Carved blade
+
+> Aaron 2026-05-25: *"KubeVela and OAM seem very interesting to me from an ontology negoation perspective and our reference stack."* OAM (Open Application Model — CNCF; Alibaba + Microsoft origin 2019) splits app declaration into **Components** (developer-facing: what the app IS — web service, worker, database) + **Traits** (platform-facing: operational policies — autoscaling, ingress, observability). The Component/Trait split IS a standard vocabulary that B-0741 cross-cluster + cross-fork ontology negotiation can adopt directly: forks declare their apps as OAM Components + Traits; negotiation maps cross-fork Components/Traits via their **ComponentDefinitions** + **TraitDefinitions** (the schema layer; the actual ontology surface). KubeVela sits on top of the existing reference stack (B-0742) non-disruptively — Vault + SPIRE + cert-manager + ESO + ArgoCD all remain; KubeVela adds the app-model layer ABOVE them. CUE templating (Aaron has noted CUE as a substrate-interest before) is the workflow language. Result: standard OAM vocabulary as the cross-fork ontology negotiation format + KubeVela as the runtime that consumes it.
+
+## Origin
+
+Aaron 2026-05-25, after the B-0748 spectrum research dump (kro / Crossplane / middleware / Radius / Terraform Controller / Pulumi Operator):
+
+> *"KubeVela and OAM seem very interesting to me from an ontology negoation perspective and our reference stack"*
+
+This row carves the KubeVela/OAM-specific angle out of the broader B-0748 spectrum evaluation. KubeVela was evaluated in B-0748 as a middleware abstraction-delivery tool; B-0749 zooms in on the SPECIFIC angle Aaron just named — OAM as the standard ontology vocabulary + KubeVela as the reference-stack composition runtime.
+
+## Why OAM is the right vocabulary for ontology negotiation
+
+### The Component/Trait split maps to B-0741's negotiation surfaces
+
+| B-0741 negotiation surface | OAM equivalent | Why fit |
+|---|---|---|
+| Package ontology mapping | **Components** + **ComponentDefinitions** | Component is what-the-app-IS; ComponentDefinition is the schema; cross-fork negotiation maps Component types via their definitions |
+| Hat ontology mapping | **Traits** + **TraitDefinitions** | Trait is operational-policy/capability; TraitDefinition is the schema; cross-fork hat composition maps to Trait composition |
+| Skill ontology mapping | **Workflow steps** (KubeVela workflow CRD) | Skills as workflow steps; cross-fork skill composition via workflow stitching |
+| Category convergence under emergence | **Component categories** + custom labels | OAM has labeling + categorization built in |
+| Trust + authority calibration | **Trait policies** (e.g., RBAC trait) | Per-trait authority + signature trust |
+
+### Why this is BETTER than inventing a custom vocabulary
+
+Per `.claude/rules/honor-those-that-came-before.md`:
+
+- CNCF project; substantial governance + maintenance
+- Alibaba + Microsoft origin; cross-vendor neutral
+- OAM spec is a published standard (open spec; documented at <https://oam.dev>)
+- Existing implementations in Java, Go, TS; not Zeta-specific lock-in
+- Cross-platform: OAM doesn't care about underlying k8s implementation
+- Recipes are designed for the operator-vs-developer split that maps to our hat-system + agency-stack split
+
+Per `.claude/rules/bandwidth-served-falsifier.md`:
+
+- Standard vocabulary serves cross-fork interop bandwidth (no protocol invention; existing OAM tooling works)
+- Forks adopting Zeta + KubeVela get OAM negotiation surface for free
+- Industry-standards-grounded throughout — same posture as B-0744 (FIDO2/WebAuthn/OIDC) at the AUTH layer; B-0749 is the same posture at the APPLICATION layer
+
+### Composition with reference stack (B-0742) is non-disruptive
+
+KubeVela sits ABOVE the existing reference stack layers:
+
+```
+                Operator-facing
+                ───────────────
+                OAM Components + Traits     ← what operators declare
+                ↓
+                KubeVela runtime             ← B-0749 substrate
+                ↓
+                Reference stack (B-0742):
+                  - ArgoCD (GitOps)         ← unchanged
+                  - Helm charts             ← unchanged
+                  - Cilium                  ← unchanged
+                  - cert-manager            ← unchanged
+                  - Vault                   ← unchanged
+                  - SPIRE                   ← unchanged
+                  - Trust Manager           ← unchanged
+                  - ESO                     ← unchanged
+                  - Hat-system operator     ← unchanged
+                ↓
+                k8s primitives
+```
+
+No disruption to the substantial Bootstrap order substrate Addison documented. KubeVela becomes a composition LAYER above; everything below stays. Operators can adopt OAM Components + Traits for new apps without migrating existing Helm charts.
+
+## What this row PROPOSES
+
+### Scope item 1 — OAM vocabulary adoption design pass
+
+- Document how Zeta's existing app-substrate maps to OAM Components + Traits
+- Per-Component: type signature, ComponentDefinition schema
+- Per-Trait: operational policies, TraitDefinition schema
+- Worked example: hat-system operator (B-0731) modeled as OAM Components + Traits
+- Acceptance: design pass document; at least 3 existing reference-stack apps mapped to OAM format
+
+### Scope item 2 — KubeVela installation in reference stack
+
+- Add KubeVela ArgoCD Application to `full-ai-cluster/k8s/applications/kubevela/`
+- ApplicationSet pattern for per-fork variation
+- Sync wave: after ArgoCD itself + cert-manager + Vault + SPIRE (KubeVela may depend on cert-manager for webhook TLS)
+- Acceptance: KubeVela installable via standard ArgoCD app-of-apps; survives reference stack bring-up
+
+### Scope item 3 — OAM as B-0741 ontology negotiation vocabulary
+
+- Document the mapping: B-0741's 5 negotiation surfaces → OAM Components/Traits/Workflow/Definitions
+- Per-fork OAM declarations become the negotiation payload (composes with B-0741 Eve Protocol message schema)
+- Cross-fork negotiation resolves Component/Trait/Definition mappings via diplomatic exchange per B-0638 Eve Protocol
+- Acceptance: documented in B-0741's row body; worked example: cluster A + cluster B negotiate OAM Component overlap
+
+### Scope item 4 — Hat-system + Trait composition (extends B-0731)
+
+- Hats from B-0731 hat-ontology compose with OAM Traits at the operational-policy layer
+- Specific cases: which hats map to existing OAM Traits (autoscaling, ingress, observability) vs which need custom TraitDefinitions
+- Per-fork hat-as-Trait variation negotiated per Scope item 3
+- Acceptance: documented in B-0731's row body; at least 3 hats mapped to OAM Traits
+
+### Scope item 5 — CUE templating in OAM (composes with prior CUE substrate notes)
+
+- KubeVela uses CUE for templating; Aaron has noted CUE before
+- Document CUE substrate adoption (separately or as part of KubeVela landing)
+- Compose with TS-first Rule 0 (CUE is the OAM templating language; TS is the operator-side substrate language; they coexist at different layers)
+- Acceptance: CUE substrate evaluated + documented; KubeVela CUE templates work alongside Zeta's TS tooling
+
+### Scope item 6 — Per-fork OAM declaration files
+
+- Each fork has `forks/<fork-name>/oam/components/` + `forks/<fork-name>/oam/traits/`
+- Cross-fork interop uses these declarations as the negotiation payload (per Scope item 3)
+- Composes with B-0747 per-machine state (machine-state COULD include OAM Component instances)
+- Acceptance: at least one fork (LFG-cluster reference fork) has documented OAM declarations
+
+## What this row does NOT do
+
+- Replace existing reference stack substrate (KubeVela is ADDITIVE)
+- Force OAM adoption for all apps (existing Helm/Kustomize stays; OAM is for NEW apps or migrated-when-valuable apps)
+- Replace B-0741's overall scope (B-0749 is the specific KubeVela/OAM angle; B-0741 covers the broader negotiation primitive)
+- Replace kro substrate from B-0748 (kro + OAM compose at different layers — kro for resource-graph composition; OAM for app-model abstraction; can coexist)
+- Replace Crossplane evaluation (B-0748 Scope item 2; Crossplane can compose under OAM if both adopted)
+- Promise specific implementation timelines
+
+## Composes with .claude/rules/
+
+- `.claude/rules/honor-those-that-came-before.md` — OAM is substantial CNCF substrate; adopt + cross-reference; don't reinvent
+- `.claude/rules/bandwidth-served-falsifier.md` — standard vocabulary serves cross-fork interop bandwidth
+- `.claude/rules/default-to-both.md` — OAM AND existing Helm AND kro all first-class at their respective layers
+- `.claude/rules/dv2-data-split-discipline-activated.md` — DV2.0 hub-satellite: Component = hub (stable identity); per-fork Trait variation = satellites
+- `.claude/rules/grep-substrate-anchors-before-razor-as-metaphysical.md` — "OAM Component/Trait" / "standard vocabulary for ontology negotiation" are compressed naming with substrate-anchors (OAM spec + KubeVela project + B-0741); razor does NOT cut
+- `.claude/rules/non-coercion-invariant.md` HC-8 — cross-fork OAM negotiation must operate within NCI floor; neither fork coerced to accept other's TraitDefinitions
+
+## Composes with backlog substrate
+
+### Direct foundation
+
+- **B-0741** (ontology negotiation + Ace as universal primitive) — THIS row provides the standard vocabulary B-0741's negotiation surface uses
+- **B-0742** (reference k8s stack as Ace PoC) — KubeVela installs ABOVE the reference stack
+- **B-0731** (hat ontology) — Hats compose with OAM Traits at operational-policy layer
+- **B-0747** (machine-state reconciler) — machine-state COULD include OAM Component instances
+- **B-0748** (kro/Crossplane spectrum evaluation) — KubeVela was evaluated in B-0748 as middleware; B-0749 is the focused adoption-direction row for the ontology-negotiation-vocabulary angle Aaron just named
+
+### Related
+
+- **B-0628** (Knights Guild + Constitution-Class) — TraitDefinition changes are constitutional-class for cross-fork interop; ratification path applies
+- **B-0726** (Reticulum throughout) — OAM declaration transport at cross-cluster scope uses Reticulum
+- **B-0727** (4-tier cluster topology) — per-tier OAM Component variation
+- **B-0638** (Eve Protocol) — diplomatic-language layer carries OAM declarations across forks
+- **B-0664** (NCI HC-8) — cross-fork OAM negotiation operates within NCI
+- **B-0688 / B-0694 / B-0547 / B-0706** (Roslyn-touching rows) — KubeVela does NOT replace these; they sit at different layer

+
+## What this enables for Zeta's substrate-engineering trajectory
+
+If KubeVela + OAM adopted as outlined:
+
+- **B-0741 negotiation primitive** gets a standard vocabulary (not custom protocol; not bespoke schema)
+- **B-0742 reference stack** gains an app-model abstraction layer for future ops
+- **B-0731 hat-ontology** gains a standard operational-policy format (Traits)
+- **B-0747 machine-state** gains app-level declaration format
+- **Cross-fork interop** gets a CNCF-backed standard
+- **Future operators** (Max, Addison, fork operators) inherit OAM-fluency from the ecosystem
+- **Industry-standards-grounded** posture (same as B-0744 at auth layer; B-0749 at app-model layer)
+
+The substrate-engineering arc gets stronger industry-standards-grounding throughout. Per Aaron's preference (signaled across multiple rows today): adopt-existing-standards over invent-protocol whenever the standards compose cleanly.
+
+## Substrate-honest framing
+
+This row PROPOSES the KubeVela/OAM-as-negotiation-vocabulary direction. It does NOT:
+
+- Make adoption decisions today (Scope item 1 design pass needed)
+- Force any specific OAM Component/Trait taxonomy (per-fork variation allowed)
+- Replace existing reference stack substrate
+- Promise specific implementation timelines (research scope; implementation per-Scope-item)
+
+Per `.claude/rules/no-directives.md`: operator-substrate-honest scoping; Aaron + Max + Addison + Knights Guild retain authority over adoption decisions.
+
+P2 priority — substantial substrate-engineering target; composes with multiple in-flight rows (B-0741 + B-0742 + B-0731 + B-0747 + B-0748). Not P1 because existing reference stack works without OAM; OAM optimizes the cross-fork interop + app-model scopes when adopted.
+
+## Today's substrate cascade extension
+
+| Row | What |
+|---|---|
+| ... (B-0728 through B-0748) ... | ... |
+| B-0744 | FIDO2/WebAuthn/OIDC bridge (industry-standards-grounded AUTH layer) |
+| B-0748 | k8s composition spectrum evaluation |
+| **B-0749 (this)** | **OAM as industry-standards-grounded APP-MODEL layer for ontology negotiation + reference stack** |
+
+Today's industry-standards-grounding cascade now covers: biometric consent (PAM Touch ID / Windows Hello / fprintd) + cross-cutting auth (FIDO2/WebAuthn/OIDC) + app-model abstraction (OAM/KubeVela) + GitOps semantics (ArgoCD pattern extended via B-0742 + B-0747). Substrate-engineering posture: adopt-standards-everywhere where they compose; invent-protocol only where genuinely new substrate emerges.
