# Phase 66: Expansion Qualification + ADBC Tests — Verification Report

**Phase Goal (ROADMAP.md):** Make `FROM semantic_view(...)` work through ADBC and any other client whose catalog/schema search path diverges from the extension's `query_conn` — and ship the milestone (CHANGELOG, version bump, CI green). [Release-prep deferred per project convention.]

**Verified:** 2026-05-26
**Status:** passed
**Re-verification:** No — initial verification

### Anti-Patterns Found

| File                                        | Line | Pattern                                                                                                       | Severity | Impact                                                                                                                                        |
| ------------------------------------------- | ---- | ------------------------------------------------------------------------------------------------------------- | -------- | --------------------------------------------------------------------------------------------------------------------------------------------- |
| (none)                                      | —    | No TBD/FIXME/XXX/HACK/PLACEHOLDER debt markers found in modified files; no stub returns; no orphaned imports. | —        | The migration is fully wired end-to-end; the SKIP_UNTIL_PLAN_02 constant remains in the test file but is no-op'd by MIGRATION_LANDED = True. |

Note: `SKIP_UNTIL_PLAN_02` constant remains in `test_adbc_queries.py` but is intentional documentation of how the scaffolding was gated during Plan 01; with `MIGRATION_LANDED = True` (line 99) the gating branch in `_SCENARIOS` is never taken. Not a stub.

### Probe Execution

Not applicable — Phase 66 has no project-convention `scripts/*/tests/probe-*.sh` probes declared in PLAN frontmatter or SUMMARY. Behavioral spot-checks (above) cover the runnable verification surface.

### Human Verification Required

None.

The PLAN files declared two `checkpoint:human-verify` gates (Tasks 3 in Plan 01; Tasks 4 and 6 in Plan 02; Task 2 in Plan 03). All four were handled by the executor in sequential-executor mode with results recorded in the SUMMARY files; the verifier has independently re-run the key automated checks (`just test-adbc-queries` 7/7 PASS) and confirmed the resolution-section prose reads coherently. No outstanding human-only checks remain (no visual UI, no real-time behavior, no external-service integration in scope).

### Gaps Summary

No in-scope gaps. EXPAND-CTX-01..03 are fully satisfied across Plans 01-03:

- **EXPAND-CTX-01:** Mechanical migration applied at all 10 expand-path emission sites across 4 files (`src/expand/sql_gen.rs`, `semi_additive.rs`, `window.rs`, `materialization.rs`). `build_materialized_sql` signature threads `def` correctly. Zero bare `quote_table_ref(` calls remain in the four expand-path files.
- **EXPAND-CTX-02:** `test/integration/test_adbc_queries.py` exists with 7 scenarios (covering all 5 required categories from the requirement: main / FACTS / semi-additive / window / multi-DB ATTACH, plus non-default-schema and materialization-routing derivatives). Wired into `just test-all` via the `test-adbc-queries` recipe. Live re-run 7/7 PASS. The Plan 02 SUMMARY transparently records that the EXPAND-CTX-01 root cause dissolved on milestone/v0.10.0 HEAD (Phase 65 per-call Connection model), so the test scaffold no longer reproduces the predicted baseline failure — the migration retains defense-in-depth value (qualified emission is the safer architectural form) and the test remains a regression guard.
- **EXPAND-CTX-03:** `_notes/error_with_adbc.md` updated in-place with a `## Resolution (v0.10.0)` section citing commit SHAs (b55936f, b116553, 9fe1ae5), pointing at `qualify_and_quote_table_ref`, `test_adbc_queries.py`, and `just test-adbc-queries`. Original 28-line downstream-reporter content preserved verbatim below a horizontal-rule divider.

REL-01 / REL-02 / REL-03 are classified as `deferred_release_prep` per `feedback_defer_release_tasks.md` and the ROADMAP.md Phase 66 footer ("REL-01/REL-02/REL-03 deferred to milestone close per `feedback_defer_release_tasks.md` — not in Phase 66 scope."). They will be handled by the upcoming `/gsd:complete-milestone` workflow, not by re-opening Phase 66.
