### Completeness

| Metric | Value |
|--------|-------|
| Tasks total | 10 |
| Tasks complete | 10 |
| Tasks incomplete | 0 |

Assessment:
- All tracked change tasks in `tasks.md` are marked complete.
- The approved persistent Task* slice is complete for verification purposes.

### Build & Test Execution

**Formatting**: ✅ Passed  
Command: `cargo fmt --manifest-path clients/agent-runtime/Cargo.toml --all -- --check`

**Focused runtime tests**: ✅ Passed  
Command: `cargo test --manifest-path clients/agent-runtime/Cargo.toml --test task_runtime_parity`
- 5 passed / 0 failed / 0 skipped
- Covers session visibility enforcement, `TaskGet`, invalid `TaskList` inputs, reopen rejection, `TaskStop` on `in_progress`, invalid `TaskCreate` priority enum handling, unsupported `subtasks` / `dependencies` payload rejection, and `TaskUpdate(status=cancelled)` rejection guidance

**SQLite task persistence tests**: ✅ Passed  
Command: `cargo test --manifest-path clients/agent-runtime/Cargo.toml sqlite_task`
- 6 passed / 0 failed / 0 skipped
- Includes direct assertion that `updated_at` advances on update in the SQLite round-trip test

**Unsupported backend tests**: ✅ Passed  
Command: `cargo test --manifest-path clients/agent-runtime/Cargo.toml rejects_persistent_task_operations`
- 6 passed / 0 failed / 0 skipped

**Bootstrap inventory test**: ✅ Passed  
Command: `cargo test --manifest-path clients/agent-runtime/Cargo.toml bootstrap_code_profile_only_exposes_task_tools_when_backend_supports_them`
- 2 passed / 0 failed / 0 skipped

**Docs checks**: ✅ Passed  
Command: `make docs-check`
- Docs workspace validation, Astro check, Biome check, and metadata validation all passed

**Clippy**: ❌ Not rerun in this verification pass  
Per completed task `5.1`, the change records that full `cargo clippy --all-targets -- -D warnings` remains red because of unrelated pre-existing repository warnings outside this slice. No slice-local clippy evidence was surfaced in prior verify output.

**Coverage**: ➖ Not configured in `openspec/config.yaml`

### Correctness (Static — Structural Evidence)

| Requirement | Status | Notes |
|------------|--------|-------|
| Minimal persistent task record model | ✅ Implemented | Shared task types and memory seam additions align with spec. |
| Persistent storage via runtime memory seam | ✅ Implemented | `SqliteMemory` stores tasks in `workspace/memory/brain.db`. |
| New native `Task*` tools | ✅ Implemented | All five tools exist and are registered. |
| SQLite-only support with fail-closed unsupported behavior | ✅ Implemented | Explicit unsupported-backend error path remains intact for non-SQLite backends. |
| Inventory/profile exposure | ✅ Implemented | Code profile inventory gates task tools on backend support. |
| Published parity mapping/docs | ✅ Implemented | English and Spanish docs reflect mapping and scope boundaries. |
| Non-goals not implemented | ✅ Implemented | No slice-local evidence of subtasks, dependencies, assignees, due dates, comments, tags, or scheduler reuse. |
| Session security / scope boundary | ✅ Implemented | `TaskService` uses `get_session_for_scope` and enforces fail-closed visibility for session-linked operations. |
| `TaskUpdate` contract clarity | ✅ Implemented | `session_id` was removed from the public schema and remains rejected at the service layer. |

---

### Coherence (Design)

| Decision | Followed? | Notes |
|----------|-----------|-------|
| Store tasks in `brain.db` under runtime memory seam | ✅ Yes | Implemented in `src/memory/sqlite.rs`. |
| Minimal `Memory` trait expansion + service layer | ✅ Yes | Shared memory seam plus centralized `TaskService` lifecycle rules. |
| SQLite-only backend support in v1 | ✅ Yes | Task tools are only surfaced for SQLite memory. |
| `TaskStop` as only cancel entrypoint | ✅ Yes | `TaskUpdate` rejects cancel mutations; `TaskStop` owns semantic cancellation. |
| Thin tool boundaries with strict contract | ✅ Yes | Boundary schema matches the intended public contract. |

### Distinguishing Slice-Local Issues vs Baseline Debt

**Remaining slice-local issues**
- None.

**Pre-existing baseline debt**
1. Full repo/runtime clippy remains red outside this slice from previously observed unrelated warnings.

---

### Issues Found

**CRITICAL**
- None.

**WARNING**
- None slice-local.

**SUGGESTION**
- None.

---

### Verdict

**PASS**

All slice-local verification issues are resolved. The approved persistent Task* slice is behaviorally compliant with the spec, aligned with the design, validated by focused runtime and docs checks, and only blocked by unrelated repository baseline clippy debt outside the scope of this change.
