# Quick Task 1: Fix Dot-Qualified Table Name Issue — Verification Report

**Task Goal:** Fix dot-qualified table name issue so that references like `jaffle.raw_orders` expand to `"jaffle"."raw_orders"` in generated SQL instead of the monolithic `"jaffle.raw_orders"`.
**Verified:** 2026-02-27T22:45:00Z
**Status:** passed
**Re-verification:** No — initial verification

## Goal Achievement

### Observable Truths

| # | Truth | Status | Evidence |
|---|-------|--------|----------|
| 1 | Dot-qualified table names like `jaffle.raw_orders` expand to `"jaffle"."raw_orders"` in generated SQL | VERIFIED | `quote_table_ref` at line 150 splits on `.` and calls `quote_ident` per part; `test_dot_qualified_base_table` at line 1127 asserts `sql.contains("FROM \"jaffle\".\"raw_orders\"")` |
| 2 | Single-part table names like `orders` still expand to `"orders"` (no regression) | VERIFIED | `quote_table_ref("orders")` splits to a single-element vec, returns `"orders"` unchanged — confirmed by `simple_table_name` test at line 402 |
| 3 | Join table names with dots are also properly split and quoted | VERIFIED | `expand()` line 321 calls `quote_table_ref(&join.table)`; `test_dot_qualified_join_table` at line 1156 asserts `sql.contains("JOIN \"jaffle\".\"raw_customers\"")` |
| 4 | DuckLake integration test passes with dot-qualified base_table | VERIFIED (programmatic limit) | Fix is correctly in place; integration test requires running DuckLake environment — flagged below for human verification |

**Score:** 4/4 truths verified (truth 4 is structurally correct; runtime confirmation needs human)

### Required Artifacts

| Artifact | Expected | Status | Details |
|----------|----------|--------|---------|
| `src/expand.rs` | `quote_table_ref` function + updated `expand()` for base_table and join tables | VERIFIED | Function defined at line 150–156; call sites at lines 316 and 321; 5 unit tests in `quote_table_ref_tests` module at line 398; 2 expand integration tests at lines 1127 and 1156 |

### Key Link Verification

| From | To | Via | Status | Details |
|------|-----|-----|--------|---------|
| `expand()` | `quote_table_ref()` | base_table quoting (line 316) | WIRED | `sql.push_str(&quote_table_ref(&def.base_table))` — call confirmed at line 316 |
| `expand()` | `quote_table_ref()` | join.table quoting (line 321) | WIRED | `sql.push_str(&quote_table_ref(&join.table))` — call confirmed at line 321 |
| `expand()` | `quote_ident()` | column aliases (lines 347, 350) | WIRED (unchanged) | Dimension/metric name aliases still use `quote_ident`, not `quote_table_ref` — correct by design |

### Anti-Patterns Found

No anti-patterns detected. No TODOs, stubs, placeholder returns, or empty implementations found in the modified file sections.

### Human Verification Required

#### 1. DuckLake Integration Test

**Test:** Run `just test-ducklake` with a DuckLake/Iceberg environment that has `base_table: "jaffle.raw_orders"` defined.
**Expected:** Query resolves to `FROM "jaffle"."raw_orders"` and DuckDB correctly interprets `jaffle` as an attached catalog, returning actual data rows.
**Why human:** Requires an attached DuckLake/Iceberg catalog at runtime — cannot be verified with static code analysis.

## Summary

The fix is complete and correctly implemented. The `quote_table_ref` function (lines 150–156) splits any table reference on `.` and individually quotes each part via `quote_ident`, producing proper catalog-qualified SQL identifiers. Both call sites in `expand()` — for `base_table` (line 316) and `join.table` (line 321) — have been updated. Column aliases retain `quote_ident` as intended.

Seven new tests cover: simple names (no regression), catalog-qualified, fully-qualified three-part names, reserved words as parts, and embedded double-quote escaping within parts — plus two expand-level integration tests confirming the generated SQL fragments for dot-qualified base tables and join tables. The commit `19fc344` was confirmed in git history.

The only item not programmatically verifiable is the live DuckLake integration test, which requires a running catalog environment.
