From 05884bd13a8c0e6aa3166b25ab336b714e829c62 Mon Sep 17 00:00:00 2001 From: "claude@clouddev1" Date: Wed, 20 May 2026 21:55:02 +0000 Subject: [PATCH] 2g rework: address DA findings on type recovery + engine routing + UI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three DA critiques from the Phase-2 verification flagged real gaps; this commit closes them. 1. Type recovery row-independence (critique #1). The all-10-types test left col_blob NULL because the DSL Value enum has no Blob variant. The DA flagged this as a potential row-dependence gap. Added `database_run_select_type_recovery_works_on_empty_table` that proves column-origin metadata works on Text AND Blob columns with zero rows, pinning the invariant. The all-types test now carries an explicit comment referencing it. 2. Engine.* pattern matching against real SQLite output (critique #2). The pre-rework tests fed `translate_generic` hand-coded strings; never verified that the pinned SQLite version actually produces those wordings. Added three engine-routing tests in `tests/sql_select.rs` that produce real engine errors via `run_select` and assert catalog routing. Aggregate-in-WHERE confirms end-to-end. GROUP-BY-required and scalar-subquery are SQLite-permissive (no real error on the natural triggers), so those tests verify the matcher doesn't false-positive on benign queries + that synthetic messages route correctly. 3. Manual TUI verification (critique #3) surfaced an additional gap: `App::input_validity_verdict()` was hard-coded silent in Advanced mode, so SQL predicate warnings emitted but never reached the [WRN] indicator. Wired the verdict through to the active effective mode; updated two pre-existing tests that pinned the now-superseded "silent in Advanced" behavior; added one new test confirming a SQL `LIKE`-on-numeric warning fires the indicator. Launched the TUI, typed a representative warning-triggering SELECT, confirmed SELECT/FROM/WHERE/LIKE highlight as keyword colour AND the [WRN] indicator appears. Test totals: 1441 → 1446 passing (+5).
