## Phase Verification Summary

| Phase | Name | Status | Score | Gaps |
|-------|------|--------|-------|------|
| 19 | Parser Hook Validation Spike | PASSED | 3/3 | None |
| 20 | Extended DDL Statements | PASSED | 6/6 | None |
| 21 | Error Location Reporting | PASSED | 11/11 | None |
| 22 | Documentation | PASSED | 5/5 | None |
| 23 | Parser Proptests and Caret Integration Tests | PASSED | 8/8 | None |

## Cross-Phase Integration

**Connected exports:** 14 cross-phase connections verified
**Orphaned exports:** 3 (backward-compat, non-functional)
**Missing connections:** 0

### Integration Wiring

| From | To | Via | Status |
|------|----|-----|--------|
| Phase 19 scope decision | Phase 20 `detect_ddl_kind` | 7 prefix patterns, longest-first ordering | WIRED |
| Phase 20 `DdlKind` enum | Phase 21 `validate_and_rewrite` | Wraps `rewrite_ddl` with validation | WIRED |
| Phase 20 `sv_rewrite_ddl_rust` | `shim.cpp` `sv_ddl_bind` | FFI call at shim.cpp:147 | WIRED |
| Phase 21 `sv_validate_ddl_rust` | `shim.cpp` `sv_parse_stub` | FFI call at shim.cpp:79 | WIRED |
| Phase 20+21 parse functions | Phase 23 proptests | `use semantic_views::parse::*` | WIRED |
| Phase 21 caret positions | Phase 23 Python tests | Extension load + `ParserException` extraction | WIRED |
| Phase 20 DDL verbs | Phase 22 README | All 7 forms documented | WIRED |

## E2E Flows

| # | Flow | Status | Verified By |
|---|------|--------|-------------|
| 1 | Native DDL CREATE through full pipeline | COMPLETE | `phase20_extended_ddl.test` |
| 2 | Error with caret position (ERR-01/02/03) | COMPLETE | `test_caret_position.py` |
| 3 | Non-semantic SQL passes through | COMPLETE | `phase20_extended_ddl.test`, `phase21_error_reporting.test` |
| 4 | Proptests exercising Phase 20+21 functions | COMPLETE | `tests/parse_proptest.rs` (33 tests) |
| 5 | `test-all` quality gate covers all phases | COMPLETE | `Justfile:96` chains all 5 test suites |

## Tech Debt (Non-Critical)

### Phase 20: Extended DDL Statements
- `sv_parse_rust` FFI function declared in `shim.cpp` but never called (replaced by `sv_validate_ddl_rust` in Phase 21)
- `sv_execute_ddl_rust` FFI function exported from Rust but no C++ caller exists (backward-compat artifact)
- `detect_create_semantic_view` / `rewrite_ddl_to_function_call` backward-compat wrappers only used in unit tests

### Phase 22: Documentation
- Error behavior (clause hints, caret position, "did you mean") not documented in README — DOC-01 satisfied as written but usability gap for users encountering validation errors

## Nyquist Compliance

| Phase | VALIDATION.md | Compliant | Status |
|-------|---------------|-----------|--------|
| 19 | exists (draft) | false | MISSING |
| 20 | exists (draft) | false | MISSING |
| 21 | exists (draft) | false | MISSING |
| 22 | exists (draft) | false | MISSING |
| 23 | exists (draft) | false | MISSING |

All 5 VALIDATION.md files were created but never populated. Nyquist validation was not performed for this milestone. Run `/gsd:validate-phase {N}` for each phase to fill gaps retroactively.

## Summary

Milestone v0.5.1 DDL Polish passes the audit. All 16 requirements are triple-confirmed satisfied across VERIFICATION.md, SUMMARY.md frontmatter, and REQUIREMENTS.md traceability table. All 5 phases passed verification with no gaps. Cross-phase integration is fully wired with 14 active connections and no missing links. 5 E2E flows are complete. The only findings are 3 orphaned backward-compat exports (cosmetic) and 1 documentation gap for error behavior (not required by DOC-01).
