## Requirements Coverage

Phase 18 claims: VERIFY-01, VERIFY-02, BUILD-04, BUILD-05

| Requirement | Source Plan | Description                                                            | Status       | Evidence                                                                                           |
| ----------- | ----------- | ---------------------------------------------------------------------- | ------------ | -------------------------------------------------------------------------------------------------- |
| VERIFY-01   | 18-01       | `just test-all` passes (Rust unit tests, sqllogictest, DuckLake CI)   | ✓ SATISFIED  | 172 tests green: 149 Rust + 4 SQL + 6 DuckLake CI + 13 vtab crash. Reconfirmed in Plan 02 final gate |
| VERIFY-02   | 18-01       | At least one sqllogictest exercises native `CREATE SEMANTIC VIEW` syntax end-to-end | ✓ SATISFIED | `test/sql/phase16_parser.test` exists, is in `TEST_LIST`, exercises full DDL → query cycle (DDL-01, DDL-02, DDL-03) |
| BUILD-04    | 18-01       | `cargo test` (bundled mode) passes without C++ compilation overhead    | ✓ SATISFIED  | `cargo test` runs 42 tests; `build.rs` early-return at line 22-24 prevents C++ compilation when `CARGO_FEATURE_EXTENSION` is absent |
| BUILD-05    | 18-02       | Extension publishable to community registry (correct footer, platform binaries, no CMake) | ✓ SATISFIED | `C_STRUCT_UNSTABLE` at 0x137a15e; no CMakeLists.txt; symbols are namespaced FFI bridges only |

**Orphaned requirements check:** REQUIREMENTS.md traceability table maps BUILD-04 and BUILD-05 to Phase 18 (matching plan claims). VERIFY-01 and VERIFY-02 are also mapped to Phase 18. No orphaned requirements.

**Note:** Several Phase 18-adjacent requirements remain open by design:
- BUILD-01, BUILD-02, BUILD-03 mapped to Phases 15 and 17 (not Phase 18's responsibility)
- ENTRY-01 through ENTRY-03, PARSE-01 through PARSE-05, DDL-01 through DDL-03 are Phase 15-17 requirements — marked Pending in REQUIREMENTS.md. This is expected; Phase 18 only claims VERIFY-01, VERIFY-02, BUILD-04, BUILD-05.

## Anti-Patterns Found

Scan of all files modified in Phase 18 (Justfile, Cargo.toml, TECH-DEBT.md, test/integration/test_vtab_crash.py, test/sql/phase16_parser.test):

| File | Pattern | Severity | Impact |
| ---- | ------- | -------- | ------ |
| (none) | — | — | No TODO/FIXME/placeholder anti-patterns found in any modified file |

No empty implementations, console.log-only handlers, or placeholder components found.

---

## Human Verification Required

### 1. Full `just test-all` run

**Test:** Run `just test-all` from the project root on a machine with `uv` installed.
**Expected:** All four targets complete with zero failures: test-rust (149 Rust), test-sql (4 SQL logic), test-ducklake-ci (6 DuckLake CI), test-vtab-crash (13 Python crash reproduction).
**Why human:** The test suite requires the built extension binary and the DuckDB amalgamation files (gitignored; must be downloaded). Automated verification confirmed all artifacts are in place and tests passed per SUMMARY files; a live run confirms the state is still green.

---

## Gaps Summary

No gaps. All 9 must-have truths verified, all 4 required artifacts pass all three levels (exists, substantive, wired), all 4 key links wired, all 4 requirement IDs satisfied. No anti-patterns found.

The one human verification item is a live `just test-all` run — this is a standard quality gate (per CLAUDE.md) that can be validated by the developer before milestone closure. It is informational, not a blocker — the SUMMARY files confirm 172 tests passed on 2026-03-08.
