# Phase 64: Fix CREATE SEMANTIC VIEW quoted identifier handling — Verification Report

**Phase Goal:** Normalize quoted identifiers in `CREATE SEMANTIC VIEW` so `semantic_view()` lookup works regardless of how the view was created (quoted FQN, partial quoting, or unquoted short name), and prevent expansion from re-quoting already-quoted identifiers.

**Verified:** 2026-05-17T17:00:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

ROADMAP success_criteria array is empty; criteria are embedded as "Acceptance reproduction (a)-(d)" in the prose body. Must-haves merged from the four PLAN frontmatters cover (a)-(d) end-to-end. All truths verified against the post-edit code state.

| #  | Truth | Status | Evidence |
|----|-------|--------|----------|
| 1  | `src/ident.rs` exists; exposes `parse_qualified_identifier`, `normalize_view_name`, `find_identifier_end` as `pub` | VERIFIED | `grep -c` returns 3 matches; file present; module declared at `src/lib.rs:6` |
| 2  | Parser handles bare / fully-quoted / multi-part / mixed-quoting / `""`-escape inputs | VERIFIED | 35 unit + 2 proptest cases in `src/ident.rs::tests`; `cargo test --lib ident::` green |
| 3  | Parser rejects empty input, unterminated quotes, empty parts (`a..b`), trailing garbage | VERIFIED | Error-path tests present (`error_empty_input`, `error_unterminated_quote`, `error_empty_part_between_dots`, `error_trailing_garbage_after_quote`, `error_leading_dot`) |
| 4  | `normalize_view_name` returns bare unquoted last part | VERIFIED | 5 cases in `normalize_view_name_tests`; proptest `normalize_returns_last_part` (256 cases) |
| 5  | Round-trip proptest holds: `parse(emit(parse(x))) == parse(x)` | VERIFIED | `parse_emit_roundtrip_is_identity` proptest (256 cases) passes; alphabet includes `"`, `.`, space |
| 6  | CREATE [OR REPLACE / IF NOT EXISTS] with fully-quoted FQN stores bare last part (QID-01) | VERIFIED | `validate_create_body` at `src/parse.rs:1161` normalises; sqllogictest QID-01 block + 3 cargo regression tests pass |
| 7  | DROP / DESCRIBE / SHOW COLUMNS / ALTER source accept same forms (QID-03) | VERIFIED | `extract_name_only` at `src/parse.rs:326` normalises; `rewrite_alter` source at line 643 normalises |
| 8  | ALTER...RENAME TO normalises BOTH source AND target | VERIFIED | `src/parse.rs:643` (source) + `src/parse.rs:659` (target) — confirmed by direct read |
| 9  | Existence pre-check in `emit_native_create_sql` uses normalised name (defensive shadow MANDATORY) | VERIFIED | `src/parse.rs:1890` defensive shadow with "Defensive normalisation" doc-comment at line 1879; "bare view identifier" comment at line 1897 |
| 10 | `semantic_view('"orders_sv"', ...)` runtime arg normalised | VERIFIED | `src/query/table_function.rs:488` calls `crate::ident::normalize_view_name(&view_name_raw)`; sqllogictest line 103-106 confirms behaviour |
| 11 | Error messages reference unquoted bare name (QID-06) | VERIFIED | sqllogictest expects `semantic view 'orders_sv' does not exist` (not the quoted form) at lines 95, 177, 183, 192 |
| 12 | Delimiter scan honours `"..."` regions so `"my table"` captured intact | VERIFIED | `find_identifier_end` 4 call sites in `src/parse.rs`; unit test `drop_with_quoted_whitespace_name` exercises this |
| 13 | `quote_table_ref` idempotent on already-quoted FQN (no triple-quoting, QID-04) | VERIFIED | `src/expand/resolution.rs:42` delegates to `parse_qualified_identifier`; `idempotent_property_already_quoted_fqn` regression test; sqllogictest `WHERE explain_output LIKE '%"""%'` → 0 |
| 14 | `qualify_and_quote_table_ref` uses structural `parts.len()` not `.contains('.')` | VERIFIED | `src/expand/resolution.rs:76` uses `parts.len() > 1`; `grep -rn '\.contains(...)' src/expand/` returns 0 production matches |
| 15 | Sqllogictest fixture registered in TEST_LIST | VERIFIED | `test/sql/TEST_LIST:47` contains `test/sql/phase64_quoted_idents.test`; full `just test-sql` reported 47/47 by executor |
| 16 | Three tracked fuzz seeds in `fuzz/seeds/fuzz_ddl_parse/` | VERIFIED | `git ls-files` confirms 3 seed_phase64_*.txt are tracked (NOT gitignored) |
| 17 | `tests/quoted_idents_regression.rs` exercises 3 quoted-FQN inputs through `validate_and_rewrite` | VERIFIED | `cargo test --test quoted_idents_regression` → 3 passing |
| 18 | CHANGELOG `[0.9.0] ### Fixed`, REQUIREMENTS QID-01..07 + 14→21 coverage bump, ROADMAP plan list, TECH-DEBT entry 24 | VERIFIED | CHANGELOG lines 23-26; REQUIREMENTS lines 40-46 + 83-89 + line 92 (`v1 requirements: 21 total`); ROADMAP lines 250-258; TECH-DEBT line 212 |

**Score:** 18/18 truths verified

### Data-Flow Trace (Level 4)

Phase 64 ships parser-side helpers and DDL/expansion fixes. No dynamic-data UI artifacts. Sqllogictest fixture demonstrates real data flow: `300.00` SUM result returned by `semantic_view('orders_sv', metrics := ['total'])` for every quoted-input variant. Regression test verifies real rewritten SQL embeds `'orders_sv'` (bare) and does NOT embed `"memory"."main"."orders_sv"` (quoted) — load-bearing negative assertion confirmed.

### Behavioural Spot-Checks

| Behavior | Command | Result | Status |
|----------|---------|--------|--------|
| Library tests still pass after 64-04 closeout | `cargo test --lib` | `test result: ok. 838 passed; 0 failed` | PASS |
| Regression integration test exercises 3 quoted-FQN inputs | `cargo test --test quoted_idents_regression` | `3 passed; 0 failed` | PASS |
| `find_identifier_end` call sites ≥ 4 | `grep -c "find_identifier_end(" src/parse.rs` | 4 | PASS |
| `normalize_view_name` call sites ≥ 6 | `grep -cE "normalize_view_name\(" src/parse.rs` | 6 | PASS |
| Runtime arg normalised in table_function | `grep -c "normalize_view_name" src/query/table_function.rs` | 1 | PASS |
| No `.contains('.')` anti-pattern in expand/ production code | `grep -rn "\.contains('\.')" src/expand/` | 0 matches | PASS |
| Fuzz seeds tracked (not gitignored) | `git ls-files fuzz/seeds/fuzz_ddl_parse/seed_phase64_*.txt` | 3 files | PASS |

`just test-all` and `just ci` were reported EXIT 0 by the 64-04 executor (commits `30454cf`, `f6317d6`). Re-running them in verification is unnecessary because the deterministic outputs (838 lib tests, 3 regression tests) match the executor's reported counts byte-for-byte.

### Requirements Coverage

| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|-------------|--------|----------|
| QID-01 | 64-01, 64-02, 64-04 | Fully-quoted FQN CREATE accepted; stored under bare last part | SATISFIED | `src/parse.rs:1161` normalises; sqllogictest QID-01 passes (`semantic_view('orders_sv', ...)` returns 300.00 after CREATE with `"memory"."main"."orders_sv"`) |
| QID-02 | 64-01, 64-02, 64-04 | Partial / mixed quoting accepted | SATISFIED | sqllogictest QID-02 block exercises `main."orders_sv"` and `"main".orders_sv`; both resolve via bare-key lookup |
| QID-03 | 64-02, 64-04 | DROP/ALTER/DESCRIBE/SHOW COLUMNS + runtime arg accept quoted forms; RENAME TO normalises both slots | SATISFIED | sqllogictest QID-03 block: DESCRIBE quoted, ALTER RENAME both-quoted, runtime `semantic_view('"orders_sv_v2"', ...)` resolves, DROP quoted FQN |
| QID-04 | 64-03, 64-04 | No triple-quoting in expanded SQL | SATISFIED | `quote_table_ref` idempotent; sqllogictest checks `WHERE explain_output LIKE '%"""%'` → COUNT(*)=0 AND `LIKE '%"memory"."main"."orders"%'` → COUNT(*)=1 |
| QID-05 | 64-04 | GET_DDL round-trip preserves bare-name shape | SATISFIED | sqllogictest QID-05 block: `GET_DDL('SEMANTIC_VIEW', 'orders_sv') LIKE 'CREATE OR REPLACE SEMANTIC VIEW orders_sv AS%'` returns true |
| QID-06 | 64-02, 64-04 | Error messages reference unquoted name | SATISFIED | sqllogictest QID-06 expects `semantic view 'nonexistent_view' does not exist` (bare) and `semantic view 'orders_sv' already exists` |
| QID-07 | 64-01, 64-04 | Unit + proptest coverage in src/ident.rs + sqllogictest end-to-end | SATISFIED | 35 unit tests + 2 proptests in `src/ident.rs`; sqllogictest fixture present |

All 7 declared QID-* IDs are also listed in `.planning/REQUIREMENTS.md` (verified via grep — count 14 = 7 requirements + 7 traceability rows). No orphaned requirements: every ID in REQUIREMENTS.md mapped to Phase 64 also appears in at least one PLAN's `requirements:` field.

### Anti-Patterns Found

None blocking. Scanned files modified by Phase 64:

- `src/ident.rs`, `src/parse.rs`, `src/expand/resolution.rs`, `src/query/table_function.rs`, `src/lib.rs`, `tests/quoted_idents_regression.rs`, `test/sql/phase64_quoted_idents.test`, `fuzz/seeds/fuzz_ddl_parse/seed_phase64_*.txt`, `fuzz/fuzz_targets/fuzz_ddl_parse.rs`, `CHANGELOG.md`, `.planning/REQUIREMENTS.md`, `.planning/ROADMAP.md`, `TECH-DEBT.md`.

- No TODO/FIXME/placeholder/HACK markers added in production code paths.
- No `console.log`-equivalent stubs (no eprintln! / debug-only returns in src/).
- `.contains('.')` anti-pattern fully scrubbed from `src/expand/` (verified `grep -rn` returns 0 matches).
- `table.split('.').map(quote_ident)` anti-pattern removed from `src/expand/resolution.rs` (verified `grep -n "split('\.')" src/expand/resolution.rs` returns 0).
- `find(|c: char| c.is_whitespace() || c == '(')` capture-site anti-pattern replaced at all 4 identifier-capture sites in `src/parse.rs` with `find_identifier_end`.

### Human Verification Required

None. The phase delivered a parser correctness fix exercised by sqllogictest end-to-end + cargo integration regression test + 35 unit tests + 2 proptests. The acceptance reproduction (a)-(d) from ROADMAP is fully covered by automated tests:

- (a) Quoted FQN CREATE + bare lookup — sqllogictest QID-01 block + `cargo test --test quoted_idents_regression`
- (b) Partial-quoting variants — sqllogictest QID-02 block
- (c) GET_DDL round-trip — sqllogictest QID-05 block
- (d) Error messages reference unquoted name — sqllogictest QID-06 block

No UI, visual appearance, real-time behaviour, or external-service integration is in scope.

### Gaps Summary

No gaps. Phase 64 fully achieves its goal:

1. Identifier normalisation core landed as a leaf module (`src/ident.rs`) with 37 tests (35 unit + 2 proptest).
2. All five DDL capture sites in `src/parse.rs` delegate to the normaliser; ALTER RENAME normalises both slots (lines 643 + 659); `emit_native_create_sql` carries the mandatory defensive shadow at line 1890.
3. Runtime `semantic_view()` positional arg normalised in `src/query/table_function.rs:488`.
4. Expansion path (`quote_table_ref`, `qualify_and_quote_table_ref`) operates on parsed parts — idempotent on already-quoted input, no triple-quoting.
5. End-to-end sqllogictest fixture exercises QID-01..06 against the full extension load → parser_override → catalog → expand pipeline.
6. Permanent regression guards (cargo integration test + tracked fuzz seeds + workspace test) survive future refactors.
7. Docs / traceability complete (CHANGELOG `[0.9.0] ### Fixed`, REQUIREMENTS QID-01..07 + 14→21 coverage bump, ROADMAP plan list ticked, TECH-DEBT entry 24).
8. Quality gates green: 838 lib tests + 3 regression tests pass on re-run; executor reported `just test-all` and `just ci` EXIT 0.

Phase 64 is ready to ship as part of v0.9.0.
