# Verification Report

**Change**: capability-based-architecture-v3
**Version**: M1 design/spec contract

---

### Verdict

**PASS**

This change is complete and coherent as an M1 design/spec-only deliverable. The artifact set is
internally aligned, all tasks are complete, the change stays out of runtime implementation scope,
and the verify checklist is adequate for archive handoff.

---

### Completeness

| Metric           | Value |
|------------------|-------|
| Tasks total      | 12    |
| Tasks complete   | 12    |
| Tasks incomplete | 0     |

All tasks in `openspec/changes/capability-based-architecture-v3/tasks.md` are marked complete.

---

### Validation Scope

This is a **non-code architecture contract change**.

Runtime builds, tests, and code execution were **not run**, by design, because:

- the approved M1 scope is design/spec only,
- no runtime source files were changed,
- the user explicitly instructed that this change should be evaluated as an M1 design/spec
  deliverable rather than failed for missing runtime test/build execution.

Validation performed:

- artifact existence and completeness review,
- task completion review,
- proposal/spec/design coherence review,
- migration-boundary and security-boundary consistency review,
- verify-checklist adequacy review.

| Success Criterion                                                                                                | Status | Notes                                                                                       |
|------------------------------------------------------------------------------------------------------------------|--------|---------------------------------------------------------------------------------------------|
| M1 defines taxonomy, descriptor contract, dependency semantics, migration boundaries, security attachment points | ✅      | Covered across `proposal.md`, `spec.md`, and `design.md`.                                   |
| M1 is explicitly design/spec only                                                                                | ✅      | Repeated consistently in proposal, spec, and design.                                        |
| Canonical parity/security constraints are preserved                                                              | ✅      | Proposal, spec, and design all preserve agent/channel/gateway compatibility baseline.       |
| Later work is split into M2-M5                                                                                   | ✅      | Separate phases are clearly scoped in proposal, spec, and design.                           |
| Fake plugin architecture is explicitly prevented                                                                 | ✅      | Anti-pattern constraints prohibit dynamic plugin loading and broad runtime inversion in M1. |

### Spec Compliance Matrix (Artifact-Level)

| Requirement Group                       | Status      | Evidence                                                                                                                           |
|-----------------------------------------|-------------|------------------------------------------------------------------------------------------------------------------------------------|
| Capability taxonomy and boundaries      | ✅ COMPLIANT | `spec.md` defines executable vs descriptive capabilities, families, and what a capability is not.                                  |
| Descriptor contract                     | ✅ COMPLIANT | `spec.md` defines required shared fields; `design.md` expands schema and examples.                                                 |
| Dependency semantics                    | ✅ COMPLIANT | `spec.md` defines required vs optional semantics and deterministic validation expectations; `design.md` provides validation order. |
| Migration boundaries                    | ✅ COMPLIANT | `spec.md` keeps trait/factory/dispatcher runtime as baseline; `design.md` reinforces no runtime inversion in M1.                   |
| Security and approval attachment points | ✅ COMPLIANT | `spec.md` requires policy/approval strengthening; `design.md` maps current namespacing and approval anchors.                       |
| Anti-pattern constraints                | ✅ COMPLIANT | `spec.md` forbids fake plugin architecture, dynamic plugin loading, and registry-only claims.                                      |
| Roadmap constraints for M2-M5           | ✅ COMPLIANT | `spec.md`, `proposal.md`, and `design.md` all separate registry, resolution, execution, and rollout phases.                        |

**Compliance summary**: 7/7 requirement groups compliant for this M1 artifact-level verification.

### Correctness (Static — Structural Evidence)

| Artifact                                | Status        | Notes                                                                                          |
|-----------------------------------------|---------------|------------------------------------------------------------------------------------------------|
| `exploration.md`                        | ✅ Implemented | Provides evidence-based rationale for a design-first M1.                                       |
| `proposal.md`                           | ✅ Implemented | Scope and non-goals match M1 exactly; canonical promotion deferral is documented.              |
| `specs/capability-architecture/spec.md` | ✅ Implemented | Normative RFC 2119 spec with Given/When/Then scenarios.                                        |
| `design.md`                             | ✅ Implemented | Explains descriptor model, schema examples, migration strategy, security mapping, and roadmap. |
| `tasks.md`                              | ✅ Implemented | All M1 tasks complete and limited to non-code artifact work.                                   |
| `verify-checklist.md`                   | ✅ Implemented | Adequately maps proposal success criteria and spec requirement groups to verify review steps.  |
| `state.yaml`                            | ✅ Implemented | Ready for archive handoff after verify completion.                                             |

### Coherence (Design)

| Decision                                                  | Followed? | Notes                                                                                  |
|-----------------------------------------------------------|-----------|----------------------------------------------------------------------------------------|
| Descriptors are contracts, not runtime implementations    | ✅ Yes     | Proposal/spec/design all keep descriptors separate from runtime implementations.       |
| Preserve family boundaries explicitly                     | ✅ Yes     | Capability families remain explicit and are not collapsed into one generic type.       |
| Keep M1 behaviorally inert                                | ✅ Yes     | No runtime files changed; all artifacts maintain design/spec-only scope.               |
| Use descriptive registration as first implementation seam | ✅ Yes     | M2 is consistently scoped as descriptive registration only.                            |
| Security semantics remain attached to capability identity | ✅ Yes     | Proposal/spec/design all preserve namespaced identity and approval-sensitive metadata. |

### Verify Checklist Adequacy

`openspec/changes/capability-based-architecture-v3/verify-checklist.md` is adequate for this change
because it:

- maps proposal success criteria to the M1 artifacts,
- covers each major spec requirement group,
- checks artifact completeness,
- explicitly documents that this is a non-code verification,
- and records that canonical promotion is deferred to archive.

---

### Issues Found

**CRITICAL**: None

**WARNING**: None

**SUGGESTION**:

- During archive, ensure the canonical-promotion decision is revisited explicitly so
  `openspec/specs/` is updated only if the team still wants M1 promoted as a main spec after verify.

---

### Archive Readiness

This change is ready for archive as a verified M1 contract change, assuming archive preserves the
documented intent:

- no runtime code changes in M1,
- canonical promotion decision handled deliberately,
- later M2-M5 work remains split and incremental.
