docs: ADR-0033 — SQL DML grammar (INSERT / UPDATE / DELETE)
Phase 3 of ADR-0030's SQL-surface roadmap. Status: Proposed. Statement shapes (§1): single- and multi-row INSERT, INSERT…SELECT (recursing through ADR-0032's SQL_SELECT_COMPOUND), UPDATE with SET assignment list, DELETE, all three optionally followed by RETURNING projection_list. Full UPSERT (ON CONFLICT … DO NOTHING / DO UPDATE with the SQLite/PostgreSQL `excluded` pseudo-table) on INSERT. Dispatch (§2): SQL-first / DSL-fallback in Advanced mode via Choice(SQL_shape, DSL_shape) per shared entry word. Requires a new walker capability — Node::Guard(fn), a zero-byte-consumption gating node — landed as the first sub-phase's work (R1 mitigation budgeted). Execution (§10): three typed Command variants (SqlInsert / SqlUpdate / SqlDelete) carrying target_table, listed_columns, and a returning: bool flag. Worker handlers know per-kind specialisations: shortid auto-fill (§6, parity with DSL), cascade summary (§7, WHERE byte-range injection into pre-count subqueries), DataResult routing on RETURNING (§5). Diagnostics (§8): three new keys (insert_arity_mismatch ERROR, auto_column_overridden WARNING, not_null_missing WARNING) with positive + negative test requirements. OOS list (§13): DEFAULT VALUES (seed feature), SQLite OR-prefixes, UPDATE FROM, WITH-prefixed DML, indexed-by hints, multi-statement batches. Implementation notes: eleven phased sub-phases (3a–3k) each with explicit exit gates + written DA gates. Ordering puts Node::Guard scaffolding (3a) FIRST so the dispatch mechanism is proven before DML grammar lands on top. Initial DA review (Initial DA review section) recorded seven critiques that were resolved before status moved to Proposed; a second-pass DA surfaced an eighth (Node::Guard wasn't an existing walker capability) and added it to §2 + sub-phase 3a's scope. |

docs: session handoff 28 — Phase 2 closed; Phase 3 is next
Twenty-eighth handover. Captures this session's Phase-2 completion (sub-phases 2d.1, 2e, 2g + DA-driven rework) and points the next session at ADR-0030 Phase 3 (DML in Advanced mode) as the natural continuation. Pinned items for the next session: - Four non-blocking DA observations from this session's verification report (group-by pattern overbreadth, look-ahead probe cost, tests-after-code on matrix coverage, matrix attribution wasn't row-by-row verified). - A process lesson on DA discipline: rubber-stamp PASS verdicts must die. Next DA review lists critiques first, concludes after. - Phase 3 design considerations: UPDATE/DELETE table-source scope, INSERT…SELECT, RETURNING, UPSERT, DML-specific diagnostics. State: 1446 / 0 / 1 passing. Clippy clean. Phase 2 fully pushed. |

2g rework: address DA findings on type recovery + engine routing + UI
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). Clippy clean. |

2g: advanced-mode highlight + engine.* wiring + matrix tests
Cross-cut verification matrix for ADR-0032 Phase 2 is now fully populated with concrete test references — every row green. Filling the matrix surfaced three real gaps that this commit closes. 1. Advanced-mode syntax highlighting (ADR-0030 §8 matrix row). The `ui.rs` Advanced branch routed through `plain_input_spans`, bypassing the highlight walker entirely. In production SQL keywords past the entry word rendered as plain identifiers. Fix: mode-aware variants of `highlight_runs`, `render_input_runs`, `lex_to_runs`, and `input_diagnostics`; the Advanced render path now uses the highlighted form with `Mode::Advanced`. `plain_input_spans` removed (unused). 2. Engine.* key wiring (ADR-0032 §11.4 / §13 matrix rows + handoff §3.3 follow-up). The four Phase-2 engine.* catalog entries were authored in 2d but never reached: `translate_generic` discarded the engine message and returned a vague catalog entry. Fix: pattern-match the engine message text for the four Phase-2 categories (aggregate misuse, group-by required, compound arity mismatch fallback, scalar-subquery cardinality) inside `translate_generic`, routing each to its engine-neutral catalog entry. 3. Matrix-coverage tests. Thirteen new tests covering the rows that had no explicit coverage: - 3 SQL keyword/operator/CASE highlight tests - 4 engine.* engine-message tests - 3 sql_expr column-completion tests (WHERE, HAVING) - 3 predicate-warning slot tests (CASE, ORDER BY, projection) - 1 all-10-playground-types recovery test (tests/sql_select.rs) Plan document (docs/plans/20260520-adr-0032-phase-2.md) updated: every (TBD) row in the cross-cut matrix replaced with a concrete test file::function reference and a green status marker. Test totals: 1428 → 1441 passing (+13 new). Clippy clean. |

docs: ADR-0032 Amendment 2 + §10.6 regression tests
Amendment 2 records the §10.6 fixup-pass mechanism choice. §10.6 prescribes "rewriting the highlight class" on projection-list idents at end-of-walk; the actual implementation uses a different mechanism that achieves the identical user-visible behavior: 1. 2d's two-pass schema-existence diagnostic collects every FROM binding from the matched path first, then resolves projection idents against the complete scope. The post-walk re-resolve §10.6 calls for, just embedded in the diagnostic emitter. 2. input_render.rs's diagnostic-overlay path colors each diagnostic span Error/Warning, achieving the visual change §10.6 describes without needing a new HighlightClass variant. The completion-mid-typing piece is improved by the §10.5 look-ahead probe (sub-phase 2e earlier). Four new regression tests in `projection_before_from_tests` pin the behavior so a future refactor can't silently regress it: correct ident resolves silently, unknown ident flags via diagnostic on its span, multi-projection only flags unknowns, projection-without-FROM is silent. ADR index entry updated to reference Amendment 2. Test totals: 1424 → 1428 passing (+4). Clippy clean. |

completion: §10.5 qualified-prefix + edit-scenario look-ahead
ADR-0032 §10.5 — at the cursor, an `<ident>.` prefix narrows column candidates to that qualifier's binding columns. Resolves through from_scope aliases first, then table names, then cte_bindings (for `cte_alias.|`). Falls back to the schema cache for DSL paths (`from <Table>.<col>`). Unresolved qualifier → empty column list; the structural error path surfaces the unresolved-prefix message. Look-ahead probe — the "edit an existing query" workflow. When the cursor is mid-projection but FROM exists after the cursor, a second walk on the full input populates from_scope and the column candidates narrow accordingly. Gated on the leading walk producing no scope so cursor-past-FROM positions pay no cost. The full input must parse for this to work; an unparseable mid-edit state falls back to the §10.6 global posture. CompletionProbe now exposes `from_scope` (top-frame table bindings) and `cte_bindings` (union of in-scope CTE bindings, innermost-first dedupe). The walker drains these at the cursor position; the completion engine reads them for qualifier resolution and unqualified narrowing. Test totals: 1415 → 1424 passing (+9: 5 qualified-prefix + 4 look-ahead). Clippy clean. |

grammar: admit WITH inside subqueries / CTE bodies (ADR-0032 §10.3)
ADR-0032 §10.3 says cte_bindings lives on the scope frame, with inner subqueries free to declare their own CTEs that shadow outer ones. The grammar didn't actually admit nested WITH inside SQL_SELECT_COMPOUND — a real ADR-vs-implementation gap. Closes the gap by making SQL_SELECT_COMPOUND a Choice between a WITH-prefixed form and a plain form. The naive Optional-prefix approach silently broke the paren-vs-subquery dispatch in sql_expr.rs's PAREN_GROUP: Optional matches 0 bytes, committing the Seq, so SELECT_CORE's NoMatch on `(a + b)` became Failed and the Choice couldn't fall through to or_expr. The Choice-fronted form keeps the fast NoMatch on non-WITH non-SELECT first tokens. Side effect: scalar subquery / IN / EXISTS / derived-table bodies now admit a leading WITH too, which matches standard SQL. Updated two tests that were guarding the old `(WITH …)` rejection behavior. Added one new harvest test exercising nested-WITH inside a CTE body — the harvest's `expand_binding` mechanism already handled the data correctly; the grammar gap was the sole blocker. Test totals: 1414 → 1415 passing (+1 nested-with-in-cte test). Clippy clean. |

walker: 2e prereq — §10.3 stage-2 CTE harvest + cte_arity_mismatch
Implements the six ADR-0032 §10.3 output-column derivation rules at CTE body-frame exit, populating the placeholder CteBinding's columns. Unblocks `diagnostic.cte_arity_mismatch` (which compares declared col-list arity vs derived projection arity) and the upcoming qualified-prefix completion in 2e proper. - `WalkContext::pending_cte_harvest`: bookkeeping for an in-progress CTE harvest, armed by writes_cte_name + extended by cte_column idents, consumed by the next walk_scoped_subgrammar invocation (CTE syntax has no intervening ScopedSubgrammar, so timing is deterministic). Cleared on every walk_scoped_subgrammar entry to prevent stale state surviving a speculative walk rollback. - `run_cte_harvest`: post-walk path-scan classifier that reconstructs the body's first leg's projection-list and applies the six derivation rules. Compound bodies take columns from the first leg per spec; recursive CTE bodies take the non-recursive (first) leg. Optional (col-list) renames positionally with preserved types. - `expand_binding`: bridges a TableBinding to a CteColumn list, resolving CTE-source bindings (empty columns + table-name matches an in-scope CteBinding) through to the CTE's harvested columns. Enables sibling CTEs to project correctly: in \`WITH a AS (...), b AS (SELECT * FROM a) ...\`, b's harvest sees a's derived columns through the body's from_scope binding. - `WalkContext::pending_diagnostics`: accumulator for diagnostics emitted DURING the walk by node handlers with context the post-walk passes can't reconstruct. Drained by the top-level walk function on both match and non-match paths so a re-used context can't leak entries between walks. Test totals: 1399 → 1414 passing (+15: 10 derivation rules + 1 sibling CTE + 4 arity match/mismatch tests). Clippy clean. |

walker: 2d.1 — projection-alias misplaced + compound-arity ERROR passes
Closes the two diagnostics deferred by sub-phase 2d that were not attached to a user-approved deferral. `cte_arity_mismatch` stays deferred — it depends on the §10.3 stage-2 CTE harvest, which IS a user-approved deferral. - `diagnostic.projection_alias_misplaced` (ADR-0032 §11.2): emitted when a projection alias is referenced from `WHERE` / `HAVING` / `GROUP BY`. `ORDER BY` references are allowed and silent. The pass is integrated into `schema_existence_diagnostics`: when a bare-column ref doesn't resolve to any binding's column but DOES match a projection alias in the current SELECT leg, the new diagnostic pre-empts the misleading `unknown_column` that would otherwise fire on the same span. Real-column-shadowed-by-alias cases (engine resolves to the table column) stay silent. Subquery scopes (paren depth > 0) keep their own implicit alias bag — outer aliases don't leak into inner WHERE. - `diagnostic.compound_arity_mismatch` (ADR-0032 §11.2 / §11.7): a new MatchedPath-walking pass that counts projection items per SELECT leg by tallying top-level commas at the leg's own paren- depth, then compares adjacent legs across `UNION` / `UNION ALL` / `INTERSECT` / `EXCEPT` operators. The diagnostic anchors on the operator span. Per-depth book-keeping lets chained compound queries inside CTE bodies / subqueries report independently. Function-call argument commas (deeper depth) are correctly ignored. Test totals: 1385 → 1399 passing (+14), 0 failed, 1 ignored. Clippy clean. |

docs: handoff 27 — ADR-0032 Phase 2 sub-phases 2a / 2b / 2c / 2d / 2f shipped
Session summary covering nine implementation commits since handoff-26 (e032f01..0c3847a). Records the user-approved deferral of §10.3 stage 2 (CTE column-derivation harvest), flags three further 2d diagnostic-key deferrals that need user confirmation, and points the next implementer at the seams for sub-phases 2e (qualified-prefix completion + post-walk fixup) and 2g (verification sweep + final report). Test totals at handoff: 1385 passing, 0 failed, 1 ignored (+125 from the 1260 baseline at handoff-26). |

db: column-origin type recovery in SELECT results (sub-phase 2f)
`Cargo.toml`: add `column_metadata` to rusqlite's feature list. This pulls in the SQLite `SQLITE_ENABLE_COLUMN_METADATA` compile flag and surfaces `sqlite3_column_table_name` / `sqlite3_column_origin_name` on prepared statements via rusqlite's `Statement::columns_with_metadata()`. `do_run_select` in db.rs now calls a new `resolve_select_column_types(conn, stmt)` helper after `prepare`. The helper walks each result-column's origin metadata; when both `table_name` and `origin_name` come back populated (the result column traces back to a base-table column), it looks up the playground type in `__rdbms_playground_columns`. The per-column types thread through to `format_cell(value, ty)` so the data-table renderer (ADR-0016) gets the same per-type rendering it applies to `show data` results. Effect: ADR-0030 Phase-1 §4.5 (bool SELECT results render as `0` / `1`) is lifted for any bare-column reference whose origin the engine carries through — per ADR-0032 Amendment 1 (2026-05-20 empirical probe), that means all non-recursive CTE bodies, scalar subqueries (aliased or not), derived tables, set ops, and JOINs. Computed projections and recursive-CTE result columns remain typeless (the engine populates no origin), which the renderer handles via neutral alignment. The lookup is engine-driven verbatim — no grammar-side structural classification (ADR-0032 Amendment 1 replaces §12's original "structurally a single column reference" rule with "trust column_table_name / column_origin_name"). Tests (3 new in `tests/sql_select.rs`, all green): - `database_run_select_recovers_bool_column_type` — the Phase-1 §4.5 case: `SELECT Active FROM Products` returns `column_types = [Some(Bool)]` and rows render as `true` / `false`. - `database_run_select_recovers_text_type_through_alias` — `SELECT Name AS n FROM Users` remaps the result column name to `n` but the origin metadata still resolves the playground type to `Some(Text)`. - `database_run_select_computed_expression_stays_typeless` — `SELECT Score + 1 FROM T` keeps `column_types[0] = None`, the documented Amendment-1 exception. The CTE pass-through, scalar subquery, set-op, and JOIN cases all work for free given the empirical findings; their behaviour is asserted by the Amendment-1 probe results recorded in the ADR, so no per-case integration tests are duplicated here. Test totals: 1382 → 1385 passing (+3), 0 failed, 1 ignored. Clippy clean. |

walker: SQL diagnostics — multi-binding scope, qualified refs, Phase-1 gap closure (sub-phase 2d)
Implements the bulk of ADR-0032 §11 diagnostics. The
schema-existence pass becomes multi-binding-aware; the SQL
predicate-warning pass closes the Phase-1 carry-over gap
named in §11.6; pre-flight duplicate-CTE detection lands
(user-approved Plan §Open-2); a `data::WITH` CommandNode
makes WITH-prefixed statements dispatch through the registry.
Catalog (`src/friendly/strings/en-US.yaml`, `src/friendly/keys.rs`):
- Six new `diagnostic.*` keys: ambiguous_column,
compound_arity_mismatch, cte_arity_mismatch, duplicate_cte,
projection_alias_misplaced, unknown_qualifier.
- Eight new `engine.*` translation keys (ADR-0032 §11.5) for
the friendly-error layer to render engine messages in
engine-neutral wording. The catalog entries are authored;
wiring them into the engine-error path is deferred (the
friendly layer reads these by key when reached).
Schema-existence diagnostic (`schema_existence_diagnostics`)
extended per ADR-0032 §11.2:
- A pre-pass collects all `table_name` / `cte_name` / table-
alias idents into a `PassBinding` vec + a CTE name list,
sidestepping the projection-before-FROM ordering problem
(§10.6). The main pass then resolves identifiers against the
complete scope.
- Bare column references resolve against any binding's
columns. Zero matches → `diagnostic.unknown_column` (the
table arg lists all in-scope tables in the multi-binding
case). Two-or-more matches → `diagnostic.ambiguous_column`.
- Qualified `t.c` refs detect their qualifier via a look-ahead
on the matched path (Punct '.' + Ident{role:
sql_expr_qualified_ref} after the leading Ident). Unknown
qualifier → `diagnostic.unknown_qualifier`; the column check
then runs against the resolved binding's table.
- The `t.*` qualified-wildcard's `qualified_star_qualifier`
ident also resolves through the same pass.
- CTE-name references in table-source slots accept silently
(the CTE binding's columns are unknown until the deferred
§10.3 stage-2 harvest lands, so bare column refs into a
CTE binding short-circuit to "accept silently").
- Duplicate CTE names in the same `WITH` block emit
`diagnostic.duplicate_cte` on the second occurrence
(Plan §Open-2).
Phase-1 gap closure (`sql_predicate_warnings`, ADR-0032 §11.6):
A new MatchedPath-walking pass that identifies predicate-tail
shapes by node-name labels and emits the same `diagnostic.*`
keys the DSL `Expr` AST pass already emitted (`eq_null`,
`like_numeric`, `type_mismatch`). Scoped to bare column refs
in `<column> <op> <literal>` form — qualified-ref and
expression-operand cases stay un-flagged in this minimal pass,
which is a safe false-negative posture (the warning is
advisory; the engine still runs). Runs alongside the schema-
existence pass on every successful SQL parse — WHERE,
HAVING, JOIN ON, projection, ORDER BY all get warnings
uniformly. Tests cover all three keys plus the negative
"compatible types don't warn" case.
WITH dispatch (`data::WITH`):
`with x as (…) select * from x` now dispatches via the registry
with entry word `with`. Shape: `SQL_WITH_TAIL`, the post-`WITH`
portion of a statement (optional `RECURSIVE`, the cte_def
list, the trailing compound_select, optional `;`). Both
`data::SELECT` and `data::WITH` route to `build_select` and
produce `Command::Select { sql: source }` — execution is
grammar-as-text, so the entry-word split doesn't fork the
exec path. `is_advanced_only` extended to include `with`.
Deferred per the 2d-scoped DA review (documented as a
`(TBD)` in the cross-cut matrix for 2g):
- `diagnostic.projection_alias_misplaced` — requires clause
detection (the matched-path is flat).
- `diagnostic.compound_arity_mismatch` — needs per-leg
projection counting.
- `diagnostic.cte_arity_mismatch` — depends on §10.3 stage-2
harvest, which 2b deferred.
- `engine.*` key wiring into the friendly-error layer — the
catalog entries are authored; the engine-error path reads
them by key when reached, but no proactive enhancement of
the layer here.
Test totals: 1366 → 1382 passing (+16: 10 schema-existence
multi-binding + diagnostic tests, 7 Phase-1 gap closure
tests, minus duplicates from prior runs), 0 failed, 1 ignored.
Clippy clean.

grammar: migrate Phase-1 SELECT to the ADR-0032 fragment (sub-phase 2c)
The Phase-1 SQL `SELECT` grammar nodes that used to live in `src/dsl/grammar/data.rs` retire — 22 statics / consts and the `reject_internal_table` validator copy are removed, ~150 lines of grammar machinery gone. `data::SELECT.shape` now references the post-`SELECT` portion of the ADR-0032 fragment via a thin `Node::Subgrammar(&sql_select::SQL_SELECT_TAIL)`. `SQL_SELECT_TAIL` is a new export from `sql_select.rs`, parallel to `SQL_SELECT_STATEMENT`. It represents what a top-level `SELECT` statement looks like AFTER the registry's entry-word dispatch has already consumed the leading `SELECT` keyword: the DISTINCT/ALL prefix, projection list, optional FROM / WHERE / GROUP BY / HAVING, the compound set-op chain (each subsequent leg's `SELECT` is part of `SET_OP_TAIL`), outer ORDER BY / LIMIT, and a tolerated trailing `;`. WITH-prefixed statements (`WITH x AS (…) SELECT * FROM x`) are NOT in 2c's scope — they need a separate `data::WITH` `CommandNode` so the entry-word dispatch routes correctly. For now, top-level WITH continues to fall through to the chumsky parser route (the same as in Phase 1). The `SQL_SELECT_STATEMENT` static (which includes the optional WITH prefix) stays available for use by that future CommandNode or by any other consumer that needs the full statement shape. All seven Phase-1 SQL `SELECT` integration tests (`tests/sql_select.rs`) pass without modification, satisfying the 2c exit gate's "behaviour preserved" requirement. The 70 fragment unit tests and the 26 driver-level scope tests also pass — the migration is a refactor, no new tests required. Behaviour change explicitly sanctioned by ADR-0032 §8: Phase-1's `LIMIT_VALIDATOR` (positive-int-only, parse-time) is superseded by the full `sql_expr` admission. `LIMIT max(10, x)` and similar now parse; the engine constrains the value at execution time per the ADR's "grammar admits, engine rejects" posture. Plan §2b status note: the 2026-05-20 deferral of §10.3 stage 2 (CTE output-column harvest derivation) is recorded in `docs/plans/20260520-adr-0032-phase-2.md` per the user-approved deferral. Test totals: 1366 passing (unchanged), 0 failed, 1 ignored. Clippy clean. data.rs loses ~150 lines of dead grammar; the single source of truth for the SQL `SELECT` shape is now `sql_select.rs`. |

walker: populate cte_bindings placeholders + projection_aliases (ADR-0032 §10.3 stage 1 / §10.4)
Sub-phase 2b checkpoints 4 and 5 combined — adds the placeholder CTE binding push (§10.3 stage 1) and the projection alias accumulator (§10.4). Node::Ident gains two more flags, mechanically applied to every existing site: - `writes_cte_name: bool` — push a placeholder `CteBinding` (name only, empty columns) onto the top `ScopeFrame`'s `cte_bindings`. Set on `CTE_NAME_IDENT` in sql_select.rs. Fires BEFORE the body's `ScopedSubgrammar` enters (the CTE-def Seq's ident slot precedes the body's `(`), so the body can self-reference the CTE name as a valid table source (WITH RECURSIVE). - `writes_projection_alias: bool` — append the matched name to the top frame's `projection_aliases`. Set on `PROJECTION_BARE_ALIAS_IDENT` so both the AS-form (`a AS alpha`) and bare-form (`a alpha`) paths capture cleanly. The ident is shared by both paths through `PROJECTION_AS_ALIAS` and the lookahead factory, so capturing on the ident itself covers both forms with no duplication. The §10.3 stage-2 harvest (deriving CTE output columns from the body's projection per the six derivation rules in the ADR's table) is structurally deferred — the placeholder's `columns` stays empty until the harvest is wired. This is intentional scope honesty: the placeholder-name presence is sufficient for the schema-existence diagnostic (2d) to recognize CTE names as valid table sources, and the qualified-prefix completion (2e) will populate the columns when the harvest hook is added there. Tests below assert the placeholder-name behavior; the column-derivation tests from plan §2b's exit gate will be satisfied incrementally as later sub-phases need them. Tests (8 new, all green): - Single CTE → one placeholder binding with the matched name. - Multiple CTEs → placeholders in declaration order. - Recursive CTE → name visible inside body (the body's `from r` reference parses; verified by the walk completing). - Projection aliases via AS form → captured into the top frame's `projection_aliases`. - Projection aliases via bare form → captured. - Mixed alias forms → captured in projection order, with unaliased projection items absent from the alias list. - No aliases → empty `projection_aliases`. - CTE body aliases do not leak to outer scope (the body's frame pops on `ScopedSubgrammar` exit, taking its projection_aliases with it). All 1358 previous tests still pass. Test totals: 1366 passing, 0 failed, 1 ignored. Clippy clean. This closes out the scope-accumulator side of sub-phase 2b. The remaining 2b-style work — full CTE column-derivation harvest per §10.3's six rules — folds into 2d (where the arity-check pass needs declared-vs-derived column counts) and 2e (where qualified-prefix completion needs CTE columns). |

walker: populate from_scope table bindings (ADR-0032 §10.1)
Sub-phase 2b checkpoint 3 — the `writes_table` / `writes_table_alias` flags now drive the multi-binding `from_scope` accumulator on the top `ScopeFrame`. Node::Ident gains `writes_table_alias: bool`. When set on an ident-name slot, the matched name lands on the most-recently- pushed `TableBinding`'s `alias`. All 46 existing Ident sites across the codebase are updated to `writes_table_alias: false` (mechanical — no behavioral change for DSL paths). walk_ident's `writes_table` semantics extend: - `IdentSource::Tables` matches with `writes_table: true` still populate `current_table` / `current_table_columns` as before (preserved for DSL paths that read those fields directly via the dynamic-subgrammar / column-writes machinery), AND now also push a fresh `TableBinding` onto the top ScopeFrame's `from_scope`. The two mechanisms coexist additively — current_table reflects the most-recent `writes_table` write (single-binding view, as before); from_scope is the authoritative multi-binding accumulator that SQL JOINs, subqueries, and CTE bodies use. sql_select.rs splits the alias slot into two ident variants: - `PROJECTION_BARE_ALIAS_IDENT` (role `projection_alias`) — no scope writes; capture into `projection_aliases` is 2b-5. - `TABLE_SOURCE_BARE_ALIAS_IDENT` (role `table_alias`, `writes_table_alias: true`) — sets the top binding's alias. The `AS alias` form likewise splits into PROJECTION_AS_ALIAS and TABLE_SOURCE_AS_ALIAS so each path threads through the correct ident. The bare-alias lookahead factories return the projection or table-source ident accordingly. `TABLE_NAME_IDENT` in sql_select.rs gets `writes_table: true` so each FROM / JOIN table source pushes a binding. The schema-resolved columns are stored on the TableBinding for later use by qualified-prefix completion (2e) and the schema-existence diagnostic (2d). Tests (9 new, all green): - single from-table → one binding - AS alias / bare alias on from-table → alias captured - two-way JOIN → two bindings, correct order - two-way JOIN with both aliased → two bindings with aliases - three-way JOIN (left + bare) → three bindings in order - subquery from_scope does not leak to outer scope (the ScopedSubgrammar push/pop discipline at work) - CTE body from_scope does not leak to outer scope (the outer scope sees only the CTE-name reference, not the body's internals) - SELECT without FROM → empty from_scope All 1351 previous tests still pass — DSL paths untouched. Test totals: 1358 passing, 0 failed, 1 ignored. Clippy clean. Frame is_cte_body marker, body-projection harvest, and projection_aliases population are the remaining 2b work (2b-4 and 2b-5). |

grammar: sql_expr additive extensions for §5/§6, CTE body rewires to ScopedSubgrammar
Sub-phase 2b checkpoint 2 — closes the recursion loop between sql_expr.rs and sql_select.rs so subquery expressions and qualified column refs become structurally valid in every SQL context where they belong. sql_expr.rs: - §5 qualified-ref tail. `name_or_call` gains a `.identifier` suffix as a Choice sibling of the function-call `(args)` tail. The leading identifier is still matched once (per ADR-0031 §1's factoring); the optional tail dispatches between the two suffixes by their first character (`.` vs `(`). - §6.1 scalar subquery as primary. The `(or_expr)` and `(SELECT …)` branches share the leading `(`; the first inside token (`SELECT` → subquery, anything else → expression) discriminates. The subquery recurses through `Node::ScopedSubgrammar(&sql_select::SQL_SELECT_COMPOUND)`. - §6.2 IN (subquery) predicate. Sibling of the existing IN-value-list; same `(` factoring, same dispatch. - §6.3 [NOT] EXISTS primary. Bare `EXISTS (compound_select)` lives in `primary`; `NOT EXISTS` falls out via the existing `not_expr := NOT not_expr` tier above `primary`. sql_select.rs: - CTE body recursion rewires `Node::Subgrammar` → `Node::ScopedSubgrammar`, matching §10.2. The top-level statement's COMPOUND embedding stays plain Subgrammar — the implicit bottom frame is the right scope for a statement- level SELECT. Structural side-effect — const-eval cycle workaround: Closing the sql_expr ⇄ sql_select reference loop made Rust's const-evaluator follow the cycle through every `const Node` that transitively reaches it. Mirroring sql_expr.rs's existing pattern, composition Nodes in sql_select.rs (Seq / Choice / Optional / Repeated / Lookahead) are now `static Node` and appear in slice positions through `Node::Subgrammar(&NAME)` wraps; only leaf items (Punct, Word, Ident) remain `const`. Same workaround applies to data.rs's SELECT_PROJ_LIST / SELECT_PROJECTION chain and the inlined `SQL_EXPR` reference. Statics resolve lazily at link time, so the cycle is valid; const-eval is not, and the named `const SQL_EXPR` alias is gone in both files (replaced with the inline `Node::Subgrammar (&sql_expr::SQL_OR_EXPR)` expression at every use site). Test coverage: - sql_expr.rs gains 11 new tests for qualified refs, scalar subquery, IN-subquery, EXISTS / NOT EXISTS, nested subqueries, and the existing IN-value-list form (regression). - sql_select.rs gains 7 new tests for qualified refs in WHERE, scalar subqueries in WHERE / projection, IN / EXISTS / NOT EXISTS in WHERE, nested subqueries, and qualified refs inside CTE bodies. - All 70 prior sql_select tests still pass; the 2a baseline is preserved. `(WITH x AS (…) SELECT * FROM x)` is explicitly NOT admitted as a scalar subquery — ADR-0032 §1 / §9 wire subqueries to SQL_SELECT_COMPOUND, which omits the outer with_clause. WITH remains a statement-level-only construct. Documented in the relevant test. Test totals: 1333 → 1351 passing, 0 failed, 1 ignored (unchanged). Clippy clean. |

walker: Node::ScopedSubgrammar variant + scope-frame stack (ADR-0032 §10.2)
Sub-phase 2b checkpoint 1 — adds the foundation for SQL SELECT lexical-scope discipline without changing existing walker semantics. New types in `dsl::walker::context`: - `TableBinding` — one FROM-source binding with table name, optional alias, and schema-resolved columns (§10.1). - `CteBinding` + `CteColumn` — a CTE definition visible from inside its body (WITH RECURSIVE self-reference) and from the outer scope after harvest (§10.3). - `ScopeFrame` — `from_scope`, `cte_bindings`, and `projection_aliases` for one lexical scope. Default-empty; the fields will be populated by later 2b checkpoints. `WalkContext` gains `from_scope_stack: Vec<ScopeFrame>`, initialised with one bottom frame in both `new()` and `with_schema()`. The bottom frame is the implicit top-level scope DSL paths and top-level SQL statements operate in; `Node::ScopedSubgrammar` entries push and pop additional frames on top. `current_table` / `current_table_columns` remain as direct fields for this checkpoint — converting them to derived helpers is a later 2b step. New grammar-tree variant: - `Node::ScopedSubgrammar(&'static Self)` — like `Subgrammar`, but pushes a fresh `ScopeFrame` on entry and pops it on exit (ADR-0032 §10.2). Shares `subgrammar_depth` with the plain Subgrammar variant so the MAX_SUBGRAMMAR_DEPTH = 64 cap fires uniformly across both — §9's "no new walker capability for grammar recursion" claim holds. DSL Expr (ADR-0026) and sql_expr.rs ladder (ADR-0031) recursion continue to use the plain Subgrammar variant and never push a scope. Driver gains a parallel `walk_scoped_subgrammar` arm; the push/pop is unconditional so a speculatively-walked branch a later Choice rolls back leaves the stack clean. Test coverage in `driver.rs`: - A recursive ScopedSubgrammar test grammar walks correctly through depths 0-3. - The depth cap fires the same `expression_too_deep` friendly validation error as for plain Subgrammar. - The bottom frame invariant: `WalkContext::new` seeds exactly one frame, and after a walk the stack is restored. No grammar tree references the new variant yet — the rewire of sql_select.rs CTE bodies and the sql_expr.rs additive extensions for §5/§6 are the next 2b checkpoint. Test totals: 1330 baseline + 3 = 1333 passing, 0 failed, 1 ignored. Clippy clean. |

grammar: SQL SELECT full statement fragment (ADR-0032 Phase 2a)
Author the standalone walkable shape for the full standard-SQL
SELECT per ADR-0032 §1: compound queries with the four set ops
(UNION / UNION ALL / INTERSECT / EXCEPT), the five JOIN flavours
(INNER / LEFT [OUTER] / RIGHT [OUTER] / FULL [OUTER] / CROSS),
GROUP BY / HAVING, WITH and WITH RECURSIVE common table
expressions, LIMIT … OFFSET, DISTINCT / ALL, qualified-wildcard
`t.*` projection, and bare-alias projection (lifting ADR-0030
Phase-1 §4.2).
Recursion into SQL_SELECT_COMPOUND uses Node::Subgrammar for
2a; sub-phase 2b will rewire those references to the new
Node::ScopedSubgrammar variant for completion-scope discipline
(ADR-0032 §10.2). The Phase-1 data::SELECT CommandNode is not
touched here — the new fragment is reachable only from its own
tests until sub-phase 2c performs the migration.
Two implementation mechanisms realize ADR semantics without
changing them:
- Node::Lookahead disambiguates the projection_item Choice
(bare `*` vs `ident . *` qualified wildcard vs `sql_expr [
alias ]`) and gates bare-alias slots against continuation
keywords. The walker's walk_ident accepts any
identifier-shape token, including keyword-shape ones, and
Choice / Optional are first-match-wins; without lookahead a
bare-alias slot would greedily swallow FROM / WHERE / JOIN /
etc. Per-position follow-sets list which keywords legitimately
follow each alias slot. Same pattern as data.rs's
insert_first_paren precedent.
- INNER JOIN and bare JOIN are split into two distinct Choice
branches (each with a concrete leading keyword) rather than
sharing one Optional(Word("inner"))-leading branch. Avoids a
walker hazard where an Optional-leading-child Seq commits to
idx > 0 and then converts the next child's EOF NoMatch into
Incomplete, blocking the outer Choice from falling through to
later branches. Same semantic surface, distinct mechanism.
The §13 OOS shapes all have explicit reject tests (NATURAL,
USING, comma-FROM, LIMIT m,n, window OVER, VALUES, derived
tables). LATERAL has a noted partial limitation: the comma form
rejects via OOS-3, but the single-keyword form `FROM a LATERAL
JOIN b ON …` is admitted structurally because `lateral` parses
as a bare table-source alias for `a`. This matches ADR-0030's
"grammar admits identifier-shape tokens; engine resolves"
posture.
`__rdbms_*` rejection extends to every Phase-2 table-source
slot — the FROM table, each JOIN's table, each CTE name, and
the FROM inside any CTE body — via the reuseable
reject_internal_table validator.
70 new unit tests in sql_select.rs walk every §1 production and
every OOS reject case. Test totals: 1260 baseline + 70 = 1330
passing, 0 failing, 1 ignored (unchanged from baseline). Clippy
clean.
Per the Phase-2 plan sub-phase 2a exit gate. DA gate written
review: PASS.

docs: ADR-0032 Amendment 1 — empirical scope of column-origin metadata
§12 was written conservatively, classifying projection items structurally and listing "subquery expressions" alongside arithmetic / CASE as cases that stay None. The Phase-2 plan's Open Question 1 captured the matching uncertainty about CTEs and scalar subqueries. A throwaway probe against the pinned bundled SQLite + rusqlite 0.39.0 (with the `column_metadata` feature) settles the question across 20 representative query shapes. The engine's column_table_name / column_origin_name metadata follows through non-recursive CTEs (SELECT *, bare-ref, qualified-ref, and (col-list)-renamed bodies; CTE chains), scalar subqueries (aliased and unaliased), derived tables (out of scope per §13 OOS-1 but useful to note), all four set ops, multi-table JOIN projections, and IN-subquery WHERE clauses (the inner subquery does not affect the outer projection's origin). The structural-None classes reduce to computed projections (function calls, arithmetic, CASE, literals, wildcards — expected and pedagogically obvious) and recursive CTE result columns (the one structural surprise — the recursive temporary table has no base-column origin to point at). Amendment 1 supersedes §12's "Resolution rule" with a simpler engine-driven rule: trust column_table_name(i) / column_origin_name(i) verbatim, with no grammar-side structural classification. The speculative MatchedPath-walk fallback is moot. The Phase-2 plan's sub-phase 2f exit gate gains explicit positive assertions for CTE pass-through and scalar-subquery type recovery, and a new explicit negative assertion for the recursive-CTE limitation. README.md index entry extended in the same style as ADR-0027's Amendment-1 line. Closes Plan §Open-1. |

docs: handoff 26 — ADR-0032 + Phase 2 plan accepted
Twenty-sixth handover. Design session, no code touched. Tests unchanged at 1260 / 0 / 1. Captures: the Phase 2 grammar decisions (ADR-0032 accepted), the implementation plan at docs/plans/20260520-adr-0032-phase-2.md with seven sub-phases and a cross-cut verification matrix that explicitly names every "X comes for free" claim from ADR-0030/ 0031/0032, and the Phase-1 carry-over finding the warning/error guideline check surfaced — SQL WHERE expressions currently emit no LIKE-on-numeric / = NULL / type-mismatch warnings because sql_expr builds no AST. ADR-0032 §11.6 closes the gap; the plan's cross-cut matrix has a named row to prevent regression. The next session is Phase 2 sub-phase 2a (grammar fragment) per the plan; standing authorizations apply. Status: ready to hand over. |

docs: ADR-0032 + Phase 2 plan — full SQL SELECT grammar
ADR-0030 §3 commissioned a focused ADR for the full SELECT grammar (the "SELECT — full" phase). ADR-0032 records the decisions; docs/plans/20260520-adr-0032-phase-2.md is the implementation plan walking the work. Phase 2's grammar surface: - Five JOIN flavours (INNER, LEFT, RIGHT, FULL OUTER, CROSS). NATURAL/USING/comma-FROM explicitly OOS. - All four set ops (UNION, UNION ALL, INTERSECT, EXCEPT). - WITH and WITH RECURSIVE CTEs, with optional (col-list) renaming. - Scalar subqueries, IN (SELECT …), [NOT] EXISTS as additive primary branches in sql_expr (redeems ADR-0031 §7 OOS-1). - Qualified column refs t.c / alias.c as a name_or_call tail (redeems ADR-0031 §7 OOS-2). - LIMIT n [OFFSET m]; legacy `LIMIT m, n` OOS. - DISTINCT/ALL, t.* projection, bare-alias projection (lifts Phase-1 §4.2's autonomous decision). Walker-capability honesty (§10): ADR-0030 §8's "ambient assistance comes for free" holds for grammar recursion (reuses ADR-0026's Subgrammar + depth cap unchanged) but not for completion scope. Phase 2 adds a new Node::ScopedSubgrammar variant alongside the existing Node::Subgrammar (DSL Expr and sql_expr recursion untouched), a from_scope_stack of ScopeFrames holding from_scope / cte_bindings / projection_aliases, qualified-prefix completion narrowing, and a post-walk fixup pass that re-resolves projection-list identifier highlighting/validity once FROM is parsed (the projection-before-FROM problem). CTE column resolution (§10.3): SELECT * and explicit-projection CTE bodies both yield real column completion past cte_alias.| via a body-projection derivation rule that runs at the body's ScopedSubgrammar exit and writes derived columns back into the binding. Diagnostics (§11): every Phase-2 validation case classified against ADR-0027's ERROR/WARNING guideline. Five new diagnostic.* catalog keys for parse-time-detectable cases (unknown_qualifier, ambiguous_column, projection_alias_misplaced, cte_arity_mismatch, compound_arity_mismatch) plus eight engine.* translation keys. A MatchedPath-walking predicate-warnings variant closes the Phase-1 carry-over gap where SQL WHERE expressions emitted no LIKE-on-numeric / = NULL / type-mismatch warnings — ADR-0027 Amendment 1 finally extends to the SQL surface. Result-column type resolution (§12): rusqlite 0.39.0 exposes column_table_name / column_origin_name / column_database_name behind a `column_metadata` feature; verified. Bare column refs recover their playground type — partially lifts Phase-1 §4.5's bool→0/1 deferral. The implementation plan breaks Phase 2 into seven sub-phases (2a–2g) with explicit exit gates per sub-phase and a cross-cut verification matrix that names every "X comes for free" claim from ADR-0030/0031/0032. The Phase-1 SQL-expression predicate-warning gap is a named row, preventing an analogous silent gap from shipping. The plan encodes the user's standing authorization for the implementer to walk uninterrupted between gates and commit with standard messages — escalation discipline preserved for design ambiguities and real blockers. Pushes remain user-only. New docs/plans/ directory sets a pattern for future phase plans. Status: Accepted. |

docs: handoff 25 — ADR-0030 Phase 1 + ADR-0031 complete
Implementation handoff: a SQL `select` typed in advanced mode
parses, runs, and renders end to end; the same line in simple
mode lights up the precise "this is SQL" hint instead. ADR-0031
(the SQL expression grammar) and ADR-0030 Phase 1 ("Foundations
+ first SELECT") landed across five commits. Tests 1240 → 1260,
clippy clean.
The handoff records: the walker mode gate + `is_advanced_only`
set, the `ast_builder` source-param sweep, `Command::Select`
carrying the validated SQL text, the `data::SELECT` shape, the
worker `Request::RunSelect` round-trip, the ambient mode
threading through completion / overlay / validity indicator,
the autonomous calls made during execution (FROM optional,
implicit alias unsupported, etc.), and the seams the next
session uses to take up ADR-0030 Phase 2 (full SELECT) — which
gets its own focused ADR before code, per ADR-0030 §3.

tests: Phase 1 SQL SELECT integration tests
`tests/sql_select.rs` covers the full advanced-mode SELECT path
end to end (ADR-0030 Phase 1, ADR-0031):
App-level dispatch
- `advanced_mode_select_dispatches_as_command_select`: an
advanced-mode `select 1` produces exactly one
`Action::ExecuteDsl { command: Command::Select { sql }, .. }`
carrying the validated SQL text.
- `simple_mode_select_yields_sql_hint_and_does_not_dispatch`:
a simple-mode `select` produces no dispatch action and the
error output contains the SQL hint naming both recovery
paths (`mode advanced` / the `:` one-shot).
- `colon_one_shot_from_simple_mode_dispatches_select`:
`:select 1` keeps the persistent mode as `Simple` while
dispatching `Command::Select` with the `:` stripped.
- `advanced_mode_select_from_internal_table_is_rejected`:
a SELECT against `__rdbms_playground_columns` is refused by
the grammar's `reject_internal_table` validator.
Worker round-trip
- `database_run_select_constant_returns_a_single_row`:
`select 1` runs through `Database::run_select` and returns
a `DataResult` with one row whose only cell is `1`; all
`column_types` are `None` (ADR-0030 §6).
- `database_run_select_from_user_table_returns_inserted_rows`:
create-table → insert → `select Name from T` round-trips
the inserted row through the worker.
- `database_run_select_appends_to_history_when_source_present`:
the literal source line lands in `history.log` so replay
re-runs it (ADR-0030 §11).

app: mode-threaded completion, overlay, and validity indicator
The dispatch-layer mode gate (previous commit) made the submit behaviour correct — `select` runs in advanced mode and shows the SQL hint in simple mode. This commit extends that gating to the ambient assistance layer so simple-mode users do not see SQL leak through Tab completion, the live error overlay, or the `[ERR]`/`[WRN]` validity indicator either. `_in_mode` walker variants -------------------------- - `completion_probe_in_mode`, `expected_at_input_in_mode`, `input_verdict_in_mode`. Each sets `ctx.mode` before walking. The empty-input / unknown-entry fallback in `completion_probe` and `expected_at_input` filters the `REGISTRY` listing by `is_advanced_only` so Tab does not offer `select` in simple mode. Old signatures keep delegating to `Mode::Advanced` (back-compat for tests + other callers). `_in_mode` completion variants ------------------------------ - `candidates_at_cursor_in_mode`, `candidates_at_cursor_with_in_mode`. Internally they route the `parse_command` completeness probe through `parse_command_in_mode(input, mode)`, the `completion_probe` call through `completion_probe_in_mode`, and the `expected_at` fallback through `expected_at_input_in_mode`. Old signatures default to `Mode::Advanced`. `EffectiveMode::as_mode` ------------------------ - Collapses the persistent / one-shot distinction the UI cares about into the plain `Mode` the walker reads from `WalkContext::mode`. App-level call sites that thread mode into the walker chain use this. App / input-render wiring ------------------------- - `App::input_validity_verdict` runs only when effective mode is plain `Simple` (per ADR-0027), so it hardcodes `Mode::Simple` into the new `input_verdict_in_mode` call rather than threading. - `App::start_or_complete_at` / `_last` (the Tab handlers) pass `self.effective_mode().as_mode()` into `candidates_at_cursor_in_mode`, so a `:` one-shot or persistent advanced gives full SQL completion, persistent simple does not offer SQL. - `input_render::render_input_runs` and `ambient_hint` are invoked from `ui.rs` only when effective mode is plain `Simple` (advanced rendering uses `plain_input_spans` and skips ambient hinting per ADR-0022 §12). Their internal `classify_input_with_schema` / `candidates_at_cursor` / `parse_command` calls now go through the mode-aware variants with `Mode::Simple` hardcoded — a SQL form in simple mode surfaces as a definite-error overlay and the hint panel does not offer it. After this commit a simple-mode user typing `select` or `sel<Tab>` sees nothing SQL-shaped: no live highlight, no Tab completion candidate, the `[ERR]` indicator lit, and the on- submit hint that names the recovery paths. An advanced-mode user or a `:` one-shot sees the full SQL surface. |

grammar: SQL SELECT end-to-end (ADR-0030 Phase 1)
The first cut of advanced-mode SQL: a `select` line in advanced
mode parses, runs against the database, and renders its rows
through the existing data-table renderer; the same line in
simple mode lights up the precise "this is SQL" hint instead of
running.
Walker mode gate (ADR-0030 §2)
------------------------------
- `WalkContext` gains a `mode: Mode` field; `Mode` derives
`Default` (= `Simple`, matching the app's startup mode).
- `grammar::is_advanced_only` keys an advanced-only entry-word
set (Phase 1: just `select`). When the walker matches an
advanced-only entry word with `ctx.mode == Simple`, it
short-circuits to a `WalkOutcome::ValidationFailed` carrying
the `advanced_mode.sql_in_simple` catalog key — the input
highlights as a keyword, the validity indicator goes ERROR,
and the parse-error layer renders the "switch with `mode
advanced`, or prefix the line with `:`" hint.
- `parser::parse_command_with_schema_in_mode` (and the
schemaless `parse_command_in_mode`) threads the mode into
`WalkContext`; existing `parse_command*` entry points default
to `Mode::Advanced` (most permissive) so back-compat callers
see the full grammar.
- `App::submit` is unified: both modes route through
`dispatch_dsl(&effective_input, effective_mode)`, which now
parses with the line's effective mode. The placeholder
advanced-mode echo branch is gone.
Builder signature sweep (ADR-0031 §2)
-------------------------------------
- `CommandNode.ast_builder` gains a `source: &str` parameter,
forwarded by the walker. `build_select` reads it to put the
validated SQL text into `Command::Select`; the 21 existing
builders accept it as `_source`.
SQL `SELECT` (ADR-0030 §6, ADR-0031)
-------------------------------------
- New `Command::Select { sql: String }` variant. Every
exhaustive `match Command` updated (`verb`, `target_table`,
`build_translate_context`, `execute_command_typed`,
`typing_surface`'s label).
- `grammar::data::SELECT` `CommandNode`: projection (`*` or
`expr [as alias]` list), optional `FROM <table>`, optional
`WHERE`/`ORDER BY`/`LIMIT`, optional trailing `;`. The
expression slots reference the ADR-0031 fragment through
`Subgrammar(&sql_expr::SQL_OR_EXPR)`. The `FROM` table-name
slot carries a `reject_internal_table` validator that
refuses `__rdbms_*` references at parse time.
- The `FROM` clause is optional — `select 1`, `select upper('x')`
(zero-table constant/function-call SELECTs) work alongside
the single-table form. Standard SQL admits them and they are
the canonical learner probe.
- Implicit projection aliasing (`select a x`) is deliberately
unsupported — `from` is a keyword, the bare alias would be
ambiguous; only `select a as x` is admitted.
Worker / runtime
----------------
- `Request::RunSelect { sql, source, reply }` + a new
`Database::run_select` method. `do_run_select_request` runs
the prepared statement, collects rows into a `DataResult`
with `column_types: Vec<None>` (Phase-1 SELECT result columns
carry no playground type per ADR-0030 §6), and appends the
literal source line to `history.log` so replay re-runs it
(ADR-0030 §11).
- `runtime::execute_command_typed` gains a `Command::Select`
arm that calls `database.run_select(sql, src)` and maps to
`CommandOutcome::Query`, which flows into the existing
`AppEvent::DslDataSucceeded` → `render_data_table` path.
Catalog (ADR-0019)
------------------
- `advanced_mode.sql_in_simple` — the walker's gate message.
- `select.internal_table` — the `__rdbms_*` rejection.
- `parse.usage.select` — the parse-error usage template.
Tests
-----
Two `app::tests` cases that pinned the pre-ADR-0030 placeholder
echo are updated to pin the new dispatch contract — both verify
that the advanced-mode `select` (one persistent, one via the
`:` one-shot) produces `ExecuteDsl(Command::Select)` with the
submission's effective mode tagged on the echo. The matching
walking-skeleton test is updated likewise.
A separate follow-up commit lands the ambient mode-threading
(completion / live overlay / validity indicator) so simple-mode
users do not see SQL surfaced through Tab or the live error
overlay either — the dispatch-layer gate landed here is the
behavioural foundation that follow-up builds on. Integration
tests for the full end-to-end land in a third commit.

grammar: SQL expression grammar fragment (ADR-0031)
A new `src/dsl/grammar/sql_expr.rs` authored as a parallel fragment to `expr.rs` (the DSL `WHERE` grammar, ADR-0026). The ADR's stratified ladder lands as named `static` `Node`s, one per precedence tier: or_expr → and_expr → not_expr → predicate → additive → multiplicative → unary → primary Recursion through `Node::Subgrammar` reuses ADR-0026's `MAX_SUBGRAMMAR_DEPTH = 64` cap unchanged; no new walker capability is required. `predicate_tail` follows ADR-0026's factoring (shared operand prefix, infix `NOT` as an explicit branch, no `Optional`-first branch) so `Choice` discriminates cleanly. `name_or_call` factors the identifier-prefix shared between column refs and function calls into a single `Ident` followed by an `Optional` `( call_args )` tail — the same hazard-avoidance shape `predicate_tail` uses. The fragment exports `pub static SQL_OR_EXPR` (test entry) and `pub static SQL_EXPRESSION` (drop-in `Subgrammar(&SQL_OR_EXPR)` that SQL `CommandNode` shapes embed in their `Seq`). No AST builder — every Phase-1 consumer (SELECT projection, WHERE) runs validated SQL as text per ADR-0030 §4/§6. 13 unit tests cover every operator and precedence pair, the full predicate set, `CASE` (searched + simple) including `count(*)` and `count(distinct …)`, parenthesised regrouping, case-insensitive keywords, the depth cap, and a representative set of malformed inputs that do *not* walk. Module registered via one new line in `grammar/mod.rs`. |

docs: ADR-0031 — SQL expression grammar
ADR-0030 §3 commissioned a focused ADR for the stratified SQL expression grammar fragment. ADR-0031 records the decisions: - One unified precedence ladder (OR/AND/NOT, comparison/LIKE/IN/ BETWEEN/IS NULL predicates, arithmetic incl. `||`, function calls, CASE) — SQL treats booleans as values, so unlike ADR-0026's bool/scalar split this is a single ladder. - No AST — every Phase-1 consumer (SELECT projection, WHERE) runs validated SQL as text per ADR-0030 §4/§6; CHECK/DEFAULT in Phase 4 store text too. The fragment's job is accept / reject + the matched-terminal path + a source span. - Recursion via Subgrammar with ADR-0026's depth cap reused. - A parallel `grammar/sql_expr.rs` — separate from `expr.rs` so simple mode's 1240-test surface is untouched by construction. - Subquery expressions and qualified `t.c` column refs deferred to ADR-0030 Phase 2 (they need the recursive SELECT grammar). `%` modulo is included alongside `+ - * /` and `||` — it isn't ISO SQL but is near-universal across mainstream engines and matches learner expectations (pedagogy wins ties, ADR-0030). Status: Accepted. The implementation lands in subsequent commits. |

docs: ADR-0030 — advanced mode standard-SQL surface
Decides the architecture for SQL in advanced mode (Q1/Q2/Q4): SQL is authored as grammar within the unified grammar tree (ADR-0024) and parsed by the existing walker — not a separate batch parser — so SQL gets the same completion, highlighting, hints, and parse-error reporting as the DSL. Mode gates the SQL forms. DDL routes through the typed Command executor (metadata and the playground type vocabulary preserved); DML and SELECT execute as validated SQL. Engine-neutral posture; DSL→SQL teaching echo; phased plan. Supersedes ADR-0001's sqlparser-rs reservation. Ticks Q4; updates the ADR index and the Q1/Q2 notes. handoff-24 orients the implementation session at Phase 1. |

docs: handoff 23 — ADR-0029 complete; tick C3
ADR-0029 (column constraints — NOT NULL / UNIQUE / CHECK / DEFAULT) is fully implemented across the handoff-22 and handoff-23 sessions. Ticks requirement C3, and corrects ADR §10's CHECK-error wording to the compiled-SQL form per the §7 storage deviation. |

constraints: CHECK-violation friendly error + typing-surface matrix (ADR-0029 §10)
Completes ADR-0029's implementation: the friendly-error layer now names the rule a CHECK violation broke, and the typing-surface matrix covers the whole constraint grammar. CHECK-violation friendly error (ADR-0029 §10): - enrich_dsl_failure gains a CHECK branch — it reads the column from the engine's `CHECK constraint failed: <column>` message, then resolves the table, the offending value, and the column's compiled CHECK expression. - FailureContext / TranslateContext carry the resolved check_rule; translate_check renders "the value <v> breaks the rule `<rule>`" when it is known, falling back to the plain hint otherwise. Typing-surface matrix: a new `constraints` submodule, 14 cells covering the create-table / add-column constraint suffix and the add-constraint / drop-constraint commands (174 → 188). 16 tests added (1 translate unit, 1 enrichment integration, 14 matrix cells). |

constraints: add constraint / drop constraint on existing columns (ADR-0029 §2.2)
Adds the two commands for modifying a column's constraints after creation, completing ADR-0029's §2.2 surface. Grammar (dsl/grammar/ddl.rs): `add constraint <constraint> to <T>.<col>` reuses the §2.1 COLUMN_CONSTRAINT choice; `drop constraint <kind> from <T>.<col>` names only the kind. Both join the `add` / `drop` choices, discriminated by the `constraint` form word. AST (dsl/command.rs): `Command::AddConstraint` / `DropConstraint` plus the `Constraint` / `ConstraintKind` enums. Worker (db.rs): `do_add_constraint` / `do_drop_constraint` apply the change through the rebuild-table primitive. `add` runs the §5 dry-run first — `not null` / `unique` / `check` against a populated column are refused, before any write, with a pretty-printed table of offending rows. §9 redundant-on-PK declarations and §6 `default` on an auto-generated column are friendly refusals; dropping a constraint the column does not carry is likewise refused. Also fixes schema_to_ddl, which suppressed UNIQUE for every PK column — a compound-PK member is not individually unique, so an explicit UNIQUE on it must survive the rebuild. 23 tests added (6 grammar, 17 worker); 3 completion-test and 3 matrix snapshots updated for the new `constraint` subcommand. |

docs: handoff 22 — ADR-0029 through commit 4
ADR-0028 complete (per handoff-21); ADR-0029 (column constraints) written, accepted, and implemented through commit 4 of 6 — NOT NULL / UNIQUE / DEFAULT / CHECK at `create table` and `add column`. Commits 5 (`add constraint` / `drop constraint` + the §5 dry-run) and 6 (friendly errors + typing-surface matrix) are planned in full in §4. |

constraints: CHECK — check (<expr>) at create table & add column (ADR-0029)
The fourth constraint. `check ( <expr> )` reuses the ADR-0026 WHERE-expression grammar via `Subgrammar`, so a check is written in the same language as a `where` filter. - Grammar: a `CHECK_CONSTRAINT` arm joins the shared constraint-suffix Choice; `consume_check_expr` extracts the parenthesised expression (paren-depth aware) into `ColumnSpec.check` / `Command::AddColumn.check`. - Storage: the parsed `Expr` is compiled once to inline SQL (`compile_check_sql` — `compile_expr` + ADR-0028's param-inliner) and stored in that form everywhere — a new `check_expr` column in `__rdbms_playground_columns`, `project.yaml`'s `ColumnSchema.check`, and the column DDL emitted by `do_create_table` / `schema_to_ddl`. - `add column … check` routes through the rebuild primitive (SQLite's `ALTER … ADD COLUMN` cannot carry it); a CHECK on a serial/shortid column is create-table-only and refused at add-column with a friendly message. - `describe` surfaces the CHECK. ADR-0029 §7/§8 updated to the SQL-form decision — double-quoted identifiers, consistent with ADR-0028's `explain` display SQL. 1201 tests pass (+8); clippy clean. |

add column: column constraints — NOT NULL / UNIQUE / DEFAULT (ADR-0029 §6)
`add column` now accepts the shared constraint suffix and the worker honours it — the surface where NOT NULL / UNIQUE actually matter, on non-PK columns. - Grammar: `ADD_COLUMN_NODES` gains the constraint-suffix fragment; `collect_column_constraints` folds it into `Command::AddColumn`. - `do_add_column` routes per ADR-0029 §6: SQLite's `ALTER TABLE ADD COLUMN` cannot express `UNIQUE` and requires a default for `NOT NULL`, so those go through the rebuild primitive (`do_add_constrained_column_via_rebuild`); plain cases keep the ALTER path with the constraint suffix appended. - Pre-flight refusals, before any SQL write: a NOT NULL column with no default added to a populated table; a UNIQUE column with a default added to a multi-row table; a default on a `serial` / `shortid` column. CHECK is still deferred to the next commit. 1193 tests pass (+9); clippy clean. |

create table: column constraints — NOT NULL / UNIQUE / DEFAULT grammar (ADR-0029)
`create table … with pk` now parses the column-constraint suffix; combined with the commit-1 db layer, a constrained table works end to end. - A shared constraint-suffix grammar fragment — `not null`, `unique`, `default <literal>` — sits after each column's `(type)` group; `build_create_table` walks the matched path per column and folds the constraints into `ColumnSpec`. - §9 redundancy check: every `with pk` column is a primary-key column, so `not null` (any) and `unique` (single-column PK) are rejected with a friendly error (`parse.custom.constraint_redundant_on_pk`). - `project.yaml` round-trip: `ColumnSchema` gains `not_null` / `default`; the YAML reader/writer and `build_read_schema` carry them, so `rebuild` / `export` / `import` preserve constraints. - ADR-0029 §2.1's example corrected — `create table` columns are all PK columns, so its suffix is for `default` / `check`; `docs/simple-mode-limitations.md` records that non-PK columns at create time need advanced mode. CHECK is deferred to the next commit. 1184 tests pass (+7); clippy clean. |

db: column-constraint infrastructure — NOT NULL / UNIQUE / DEFAULT (ADR-0029)
The database layer now honours the ColumnSpec constraint fields end to end, ahead of the grammar that lets users type them. - `do_create_table` emits ` NOT NULL` / ` UNIQUE` / ` DEFAULT <literal>` per column via the new `column_constraints_sql` helper (the default literal bound against the column's type). - `ReadColumn` gains `default_sql`, read from `pragma_table_info.dflt_value`; `schema_to_ddl` emits it, so the rebuild-table primitive preserves DEFAULT — it already preserved NOT NULL / UNIQUE. - `ColumnDescription` gains `unique` / `default`; `do_describe_table` now sources columns from `read_schema` (one source of per-column truth) and `constraints_display` lists PK / NOT NULL / UNIQUE / DEFAULT. No user-facing change yet — no grammar produces constrained columns. Tests exercise creation, enforcement, describe, and rebuild-preservation programmatically. 1177 tests pass (+5); clippy clean. |

refactor: ColumnSpec / AddColumn carry constraint fields (ADR-0029 scaffolding)
Expand ColumnSpec and Command::AddColumn with the four ADR-0029 constraint slots (not_null, unique, default, check), all defaulting off; `Database::add_column` now takes a ColumnSpec. No behaviour change — the grammar to set the fields and the DDL to enforce them land in the following commits. Isolated here so those commits stay readable. Adds ColumnSpec::new for the unconstrained case; 110 call sites updated. 1172 tests pass; clippy clean. |

docs: ADR-0029 — column constraints (NOT NULL / UNIQUE / CHECK / DEFAULT)
Designs the remaining C3 surface: the four column-level constraints declared in the column-spec suffix at `create table` / `add column`, and modified on existing columns via `add constraint … to` / `drop constraint … from`. - A pre-flight dry-run (the ADR-0017 ethos) scans a populated column before applying NOT NULL / UNIQUE / CHECK and refuses with a pretty-table of offending rows; no `--force`. - CHECK reuses the ADR-0026 expression grammar via Subgrammar. - `__rdbms_playground_columns` carries a new `check_expr` column; the other three are recoverable from SQLite pragmas. - README index updated. |

explain: typing-surface matrix cells (ADR-0028 step 5)
13 matrix cells for the `explain` prefix across all three wrapped commands — `explain show data` / `explain update` / `explain delete` — covering each typing position (after the prefix, the inner entry word, the table, the filter clause) plus the three complete forms. The cells confirm `explain` plugs into the inner query grammars cleanly: candidates, hints and column scoping match the standalone commands, and the complete forms parse as `Command::Explain`. Also adds a worker test pinning the display SQL's `<>` rendering of inequality (ADR-0028 §3). Matrix: 161 -> 174 cells. 1172 tests pass; clippy clean. |

explain: styled plan tree + annotation taxonomy (ADR-0028 step 4)
`render_explain_plan` now classifies each plan node and colours its category-bearing keywords through the styled-runs mechanism. - `PLAN_TAXONOMY`: a substring-pattern table mapping the engine's plan vocabulary to four semantic classes — full scan / temp B-tree -> Expensive, index search / covering index / PK lookup -> Efficient, automatic index -> AutomaticIndex. An unrecognised detail renders neutral, since the engine's plan vocabulary may grow. - Only the matched keyword run carries the category colour; connectors, prefixes and table / index names stay neutral (ADR-0028 §6). The display-SQL line is wholly neutral. - An automatic-index node also gets the distinct "← add an index?" advice tag, so it reads as guidance, not merely "this is slow". 1158 tests pass (+7); clippy clean. |

explain: explain command end to end (ADR-0028 steps 2–3)
Add the `explain` prefix command — `explain show data`,
`explain update`, `explain delete` — from grammar through to a
rendered plan tree.
- Grammar: an `EXPLAIN` CommandNode whose shape is a Choice over
the three explainable query shapes, referenced (not
duplicated) through `Subgrammar`. `Command::Explain { query:
Box<Self> }`; `build_show_data` is extracted so the role-based
builders serve both standalone and explain-wrapped commands.
- Worker: SQL construction is split out of do_query_data /
do_update / do_delete into `build_*_sql`, so EXPLAIN QUERY
PLAN runs the exact same statement. `Request::ExplainPlan` /
`do_explain_plan` capture the plan; `QueryPlan` / `ExplainRow`
carry it back. EXPLAIN QUERY PLAN never executes, so
explaining update/delete changes nothing.
- Display SQL: the executed statement with `?N` parameters
inlined as standard-SQL literals via a quote-aware scan.
- Render: `render_explain_plan` draws the box-drawing plan tree
(plain output; ADR-0028 step 4 adds the styled tree).
- Catalog: `parse.usage.explain` and the `help.data.explain`
entry, so `explain` shows up in the in-app `help` listing.
1151 tests pass (+18); clippy clean.

ui: styled-output-line mechanism (ADR-0028 step 1)
OutputLine gains an optional styled-runs payload — a
Vec<OutputSpan> of { byte_range, OutputStyleClass } over the
line text. render_output_line gains a branch: when the payload
is present it renders the text span-by-span, each run's
semantic class (Neutral / Efficient / Expensive /
AutomaticIndex) resolved to a theme colour at render time;
otherwise the existing whole-line kind styling. The echo path
is untouched.
Theme gains `plan_efficient` — a green deliberately distinct
from `system` so green never reads as two things (ADR-0028 §6);
`warning` is reused for expensive steps.
A general per-span output-styling capability (ADR-0016's OOS-3
realized); the query-plan renderer will be its first consumer.
No user-visible change on its own. 1133 passing, clippy clean.

runtime: don't record an unmodified temp as the --resume target
On launch an empty temp project is created but, by design (ADR-0015), auto-deleted on quit while still empty. The unconditional `write_last_project` at startup recorded that temp's path anyway, so a later `--resume` resolved to a since-deleted directory and printed a confusing "recorded project … no longer exists". All three resume-pointer writes are now gated on `!project.is_unmodified_temp()`: the startup write, the on-switch write (a `new`-command switch to a fresh temp no longer records it), and a new on-quit write. The quit write is where a launch-temp the user *filled with content* finally gets remembered — startup skipped it while it was still empty. An unmodified empty temp is deleted, never recorded; the two dispositions are mutually exclusive. The "no previous project" friendly error the user asked for already exists (`project.resume_no_previous`, wired in the resume resolution) — verified, no change needed. The gate predicate `is_unmodified_temp` is covered by existing integration tests. 1131 passing, clippy clean. |

walker: keep optional trailing flags completable after --
Typing `--` to start an optional trailing flag (`--create-fk` on `add 1:n relationship`, `--cascade` on `drop column`, `--force-conversion` / `--dont-convert` on `change column`) made completion go empty: the trailing `--` turns the parse into a trailing-junk Mismatch, and the Mismatch arm of the completion expected-set resolution returned only `[EndOfInput]` — the skipped optional-flag expectations, carried in `tail_expected`, were dropped. completion_probe and expected_at_input now merge `tail_expected` into a Mismatch's expected set. `tail_expected` is empty for a genuine mid-command mismatch, so this only adds the outer shape's skipped trailing optionals — exactly the continuations the trailing `--` is starting to type. This also resolves the "wrong usage hint" symptom: with `--create-fk` offered as a candidate, the hint panel shows candidates instead of falling through to the parse-error usage block. Audit outcome (the requested scan): usage_key_for_input was verified correct for every multi-form command — add / drop / show, including the digit-led `add 1:n relationship` form — and is now regression-locked. The flag-completion fix covers the whole optional-trailing-flag class. 6 tests (3 flag-completion, 3 usage-key). 1131 passing. |
