claude@clouddev1 12395a9a6c 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.

claude@clouddev1 d17addddd7 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.

claude@clouddev1 827b47f88f walker: schema-existence ERROR diagnostics (ADR-0027 step B)
`MatchedKind::Ident` now carries its `IdentSource`. A
post-walk pass over a structurally-valid parse flags a
matched `Tables` ident that is absent from the schema, or a
`Columns` ident absent from the table in scope, as an ERROR
diagnostic — the command parses but would fail at execution
(ADR-0027 §2). New behaviour: an unknown table / column used
to parse cleanly and fail only when run.

Column scope is resolved by one left-to-right pass over the
matched path (every command places its table ident before
the columns that belong to it); an unknown table clears the
scope, so its columns are not cascaded into a second
diagnostic. New catalog keys `diagnostic.unknown_table` /
`diagnostic.unknown_column`.

claude@clouddev1 f75f71bbe4 WHERE expressions: wire into update/delete/show data + SQL gen (ADR-0026 steps 3-4)
Wires the stratified WHERE-expression fragment into the three
filter commands and compiles the resulting Expr to SQL.

Grammar (data.rs): the `update` / `delete` `where` clause is
now the expression fragment (`Subgrammar(&expr::OR_EXPR)`) in
place of the single `col = val` slot; `show data` gains an
optional `where <expr>` and an optional `limit <n>` (a
non-negative integer, validated at parse time). The
expression's right-hand operands are a schema-aware
`DynamicSubgrammar` so the hint panel still narrows to the
left column's type (ADR-0026 §8) — but the inner grammar is
permissive: a type-mismatched literal still parses (§7).

AST: `RowFilter::Where{column,value}` -> `RowFilter::Where(Expr)`;
`ShowData` gains `filter: Option<Expr>` and `limit: Option<u64>`.
A `RowFilter::eq` convenience constructor keeps simple-equality
call sites and tests readable.

SQL (db.rs): `compile_expr` lowers an `Expr` to a
parameterised WHERE — every literal a `?` placeholder,
identifiers `quote_ident`-quoted, `<>` for inequality. A
literal compared against a column binds through that column's
type where compatible and falls back to its syntactic shape on
a mismatch (§7 — permissive). `show data ... limit n` emits
`LIMIT ?` with an implicit primary-key `ORDER BY`, so it is a
stable "first n by primary key".

completion.rs: `invalid_ident_at_cursor` no longer mis-flags a
digit-led literal (`1`) as an unknown column now that the
WHERE operand slot also accepts a column reference; a
`ProseOnly` slot suppresses keyword candidates even when the
expected set also carries a column ident.

11 db integration tests cover AND / OR / NOT, BETWEEN, IN,
LIKE, filtered `show data`, and limit ordering; walker and
expr unit tests cover the parse surface. Type-mismatch /
`= NULL` diagnostic flagging (§7 highlight + hint) is the
remaining ADR-0026 piece.

claude@clouddev1 6d2b92996d Grammar: remove the dead CommandNode.hint_mode field
HintMode became per-node (Node::Hinted) in the node-attached refactor;
the per-command hint_mode field was never the mechanism and is now
read by nothing. Removed the field and its 20 `None` initialisers.

claude@clouddev1 90e3f5dbfb Insert grammar: Form C type-awareness via lookahead (ADR-0024 §Phase D)
Form C (`insert into T (vals)`) shared the `(` opener with Form A,
so its paren was an untyped Repeated(Choice(literal, ident)) — values
weren't type- or count-checked at parse time (handoff-12 §2.2).

New Node::Lookahead variant: a factory that peeks the source. The
insert first-paren factory inspects the first token — a value literal
routes the contents through the typed column_value_list (Form B
dispatch contract: per-non-auto-column typed slots); an identifier or
empty paren routes to a Form A column-name list. So Form C now gets
the same per-column typed slots, hints, and parse-time type/count
checking Form B has.

The explicit-Choice-branch split is impossible here (committed-choice
semantics commit after `(` matches); lookahead is the only route, and
DynamicSubgrammar factories couldn't see the source. Node::Lookahead
is not memoized — its output depends on source — but it returns only
a small node (a Repeated, or a thin DynamicSubgrammar wrapper that
delegates to the memoized column_value_list).

`insert into T (` now cleanly shows Form A column candidates instead
of mixed Form-A/C suggestions. Form C matrix tests updated for the
type-aware behaviour.

claude@clouddev1 911a537a83 Walker: node-attached HintMode via Node::Hinted (ADR-0024 §HintMode-per-node)
Replaces the hint resolver's signature-matching (does the expected set
contain all five literal forms? an Ident{NewName}?) with a grammar-
declared annotation. New Node::Hinted { mode, inner } wrapper; the
walker records the mode in WalkContext::pending_hint_mode on entry and
clears it on any successful match (cursor moved past the slot — this
also undoes the leak where a failed Hinted branch of a Choice would
otherwise strand a stale mode). The resolver reads pending_hint_mode
directly.

Value-literal fallback slots carry ProseOnly; NewName ident slots carry
ForceProse. hint_mode_at_input_inner now delegates to
hint_resolution_at_input — one resolution path, no duplicated logic.
No behaviour change; the typing-surface matrix guards it.

claude@clouddev1 0b15ce0306 Walker + parser: surface mid-typing after separators and Form C/A ambiguity
The typing-surface matrix exposed two bugs the existing 859-test suite
missed:

walk_repeated: when the separator consumed but the inner item failed
at EOF, the old path rolled the separator back and reported a definite
error at the rollback position (`insert into T (a, ` flashed red on
the `,` after each comma). Now propagates Incomplete with the inner's
expected set so the input renderer treats it as mid-typing.

build_insert Form C path: `insert into T (col)` walked to a complete
match but produced `values: []` because Form C's value collector drops
ident-shaped items. The user almost certainly meant Form A and just
hasn't typed `values (...)` yet. Reject with a ValidationError naming
the Form-A continuation; classify_input now reports IncompleteAtEof.

completion_probe / expected_at_input: ValidationFailed used to return
an empty expected set, leaving Tab with nothing to offer at the new
Form-A flag point. Now surface result.tail_expected (skipped-Optional
expectations captured before validation fired) so `values` is still
offered as a candidate.

claude@clouddev1 b3f1a20652 Phase D: insert value list mirrors do_insert's user_cols contract
Bug: hint at \`insert into Customers values (\` for a Customers
table with id:serial PK suggested typing an integer for \`id\`,
but the dispatch path (\`db::do_insert\`) deliberately doesn't
accept user-supplied values for auto-generated columns in
Form B. The grammar prompted for a value the dispatch would
refuse.

The fix aligns Phase D's \`column_value_list\` dynamic sub-grammar
with do_insert's three forms (ADR-0014 + ADR-0018 §3):

- **Form A** \`insert into <T> (col1, col2, …) values (…)\` —
  user explicitly lists columns. Slot list mirrors that
  selection; serial / shortid columns CAN appear if the user
  lists them.
- **Form B** \`insert into <T> values (…)\` — bare values. Slot
  list = non-auto-generated columns of the table in
  declaration order. Serial / shortid get auto-filled by the
  dispatch; the grammar doesn't prompt for them.
- **Form C** \`insert into <T> (v1, v2, …)\` — bare value list.
  Not affected by this change (column_value_list isn't on this
  path; Form C's literals route through the schemaless
  INSERT_PAREN_LIST).

Implementation:

\`WalkContext.user_listed_columns: Option<Vec<String>>\` — when
\`Some\`, signals Form A; \`None\` is Form B. Populated by walking
the first paren's column-list idents.

\`Node::Ident.writes_user_listed_column: bool\` — new field;
\`true\` on the INSERT_PAREN_ITEM's Ident child. When the
walker matches that ident in Form A, it appends the
schema-canonical column name (case-corrected against the
schema) to user_listed_columns.

\`column_value_list\` factory:
- If user_listed_columns is Some → resolve each name from the
  schema; one typed slot per listed column.
- Else → filter current_table_columns to non-auto-generated;
  one typed slot per remaining column.
- Empty result → fall back to the schemaless value-literal
  list (a serial-only table in Form B has nothing for the
  user to type).

Tests:
- New \`phase_d_insert_form_b_skips_serial_column\` confirms the
  bug: \`insert into Customers values (1, 'Alice')\` against a
  Customers with serial id rejects at parse time (Form B
  expects 1 value for Name, not 2).
- New \`phase_d_insert_form_a_accepts_serial_when_listed\`
  confirms \`insert into Customers (id, Name) values (1, 'Alice')\`
  works.
- New \`phase_d_insert_form_a_filters_to_user_listed_columns\`
  confirms partial Form A (\`(Name) values ('Alice')\`).
- Updated \`phase_d_insert_with_schema_accepts_typed_values_per_column\`
  to match the new Form B contract (2 user-typed values, not 3).
- Updated typed-hint test matrix split into form-B (8 types)
  and form-A (serial / shortid).
- New \`typed_hint_form_b_skips_serial_column_to_generic_or_text_neighbor\`
  pins the fallback behavior for a serial-only table.

For the user: \`insert into Customers values (\` for a Customers
with \`(id:serial, Name:text, Email:text)\` now hints
\`for \`Name\`: Type a quoted string …\` (skipping id entirely)
and accepts exactly 2 values. To set the serial explicitly,
use Form A: \`insert into Customers (id, Name, Email) values
(1, 'Alice', 'a@b.c')\`.

Tests: 851 passing, 0 failing, 1 ignored. Clippy clean.

claude@clouddev1 abebd7944f ADR-0024 Phase D (full): schema-aware value typing
Schema-aware typed value slots — the central design claim of
ADR-0024 §Phase D. Insert / update / delete value slots now
dispatch on the user-facing column type at parse time, rejecting
mis-shaped input with localised wording instead of waiting for
the bind-time error.

What changed:

**SchemaCache extension** (`src/completion.rs`):
- New `TableColumn { name, user_type }` for per-table column
  metadata.
- `SchemaCache.table_columns: HashMap<String, Vec<TableColumn>>`.
- `SchemaCache::columns_for_table(name)` — case-insensitive
  lookup, mirrors the walker's case-insensitive entry-word
  resolution.

**WalkContext schema plumbing** (`src/dsl/walker/context.rs`):
- `WalkContext<'a>` gains a lifetime and a `schema: Option<&'a
  SchemaCache>`. `WalkContext::new()` keeps the schemaless
  default; `with_schema(s)` is the new schema-aware constructor.

**Parser entry point** (`src/dsl/parser.rs`):
- `parse_command_with_schema(input, schema)` is the new public
  schema-aware variant. `parse_command(input)` becomes a thin
  wrapper that delegates with `None` for back-compat.
- Internal `try_walker_route` accepts an `Option<&SchemaCache>`
  and threads it into the WalkContext.

**Node::Ident writes_table/writes_column** (`src/dsl/grammar/mod.rs`):
- Two new fields on `Node::Ident`. When `writes_table: true` and
  `source: Tables`, the walker writes the matched ident's name
  into `current_table` and resolves `current_table_columns`
  against the schema cache. When `writes_column: true` and
  `source: Columns`, the walker writes the resolved
  `TableColumn` into `current_column`.

**Walker driver DynamicSubgrammar dispatch** (`src/dsl/walker/driver.rs`):
- The `Node::DynamicSubgrammar(factory)` branch now resolves the
  factory at walk time and `Box::leak`s the result so its inner
  static-slice fields (Choice/Seq) have the lifetime the walker
  expects (per ADR-0024 §sub-grammars). The leak is bounded by
  command-shape complexity per walk; per-walk arena is a future
  optimisation.
- `walk_ident` extends to perform the schema writes when the
  flags are set.

**Typed value slot factories + dynamic sub-grammars** (`src/dsl/grammar/shared.rs`):
- `int_slot` / `real_slot` / `decimal_slot` / `bool_slot` /
  `text_slot` / `date_slot` / `datetime_slot` / `blob_slot` —
  one per `Type`. Each accepts the appropriate literal kind plus
  `null`; integer-only validator rejects `3.14` at int columns;
  decimal validator pins numeric shape.
- `slot_for_type(ty) -> Node` is the dispatcher.
- `current_column_value(ctx) -> Node` is the dynamic sub-grammar
  for `set col = …` and `where col = …` values; reads
  `current_column` and dispatches via `slot_for_type`.
- `column_value_list(ctx) -> Node` is the dynamic sub-grammar
  for `insert into T values (…)`; reads `current_table_columns`
  and unfolds a Seq of typed slots separated by commas.
- Both fall back to the schemaless `VALUE_LITERAL` choice when
  the context lacks the schema-resolved entries — keeps
  schemaless `parse_command` callers (tests, replay path)
  working.

**Data-command grammar wires the new types** (`src/dsl/grammar/data.rs`):
- `TABLE_NAME_INSERT` / `TABLE_NAME_WRITES` (new): table-name
  slots that set `writes_table: true`. Used by insert / update /
  delete to populate `current_table_columns`.
- `SET_COLUMN` / `FILTER_COLUMN` (new): column-name slots in
  `set col=…` / `where col=…` set `writes_column: true`.
- `INSERT_VALUES_LIST` becomes `DynamicSubgrammar(column_value_list)`.
- `UPDATE_ASSIGNMENT` and `WHERE_CLAUSE` use
  `PER_COLUMN_VALUE = DynamicSubgrammar(current_column_value)`.

**Runtime plumbs schema-with-types** (`src/runtime.rs`):
- `refresh_schema_cache` calls `describe_table` for each table
  and populates `SchemaCache::table_columns` with
  `TableColumn { name, user_type }` entries. Best-effort: a
  `describe_table` miss leaves that table unpopulated and the
  walker falls back to schemaless dispatch.

**App dispatches with schema** (`src/app.rs`):
- `dispatch_dsl` routes through `parse_command_with_schema(&self
  .schema_cache, …)` so live typing/dispatch sees the typed
  slots. The replay path stays schemaless (deferred — replay
  bind-time errors still catch type mismatches).

**Catalog** (`src/friendly/strings/en-US.yaml`, `src/friendly/keys.rs`):
- New `parse.custom.bind_type_mismatch` entry with `{found}` and
  `{expected}` placeholders. Surfaced by the int_slot /
  decimal_slot validators.

Tests:
- 11 new walker-side Phase D tests cover insert / update /
  delete with schemas — typed acceptance per column, decimal
  rejection at int columns, null acceptance at any slot,
  multi-assignment per-column dispatch, schemaless fallback.
- The pre-existing `parse_command(input)` test suite (no
  schema) still passes — the fallback path is behaviour-
  preserving.
- 828 passing total, 0 failing, 1 ignored. Clippy clean.

claude@clouddev1 a41400e532 ADR-0024 Phase F (full) step 2: usage via CommandNode.usage_ids
Migrates parse-error usage-block rendering from the legacy
`dsl::usage::matched_entry` (which scanned a `Vec<Token>` for the
first matched Keyword) to walker-side lookup driven by each
`CommandNode`'s `usage_ids` slice.

`CommandNode.usage_id: Option<&'static str>` becomes
`usage_ids: &'static [&'static str]`. Multi-form families
(`drop`, `add`, `show`) carry every variant — `drop` lists
table/column/relationship templates; `add` lists column /
relationship; `show` lists data / table. The single-shape
commands carry their single catalog key.

App-lifecycle CommandNodes had pointed at non-existent
`parse.usage.app.*` keys (never noticed because the field was
unused); they now point at the real catalog entries
(`parse.usage.quit`, `parse.usage.help`, …).

New helpers in `dsl::grammar`:
- `usage_keys_for_input(source) -> Option<(entry_word, usage_ids)>`
  resolves the first identifier-shape token to a CommandNode and
  returns its usage_ids list. Used by `app::render_usage_block`
  and `input_render::ambient_hint`.
- `entry_words_alphabetised() -> Vec<&'static str>` replaces
  `dsl::usage::entry_keywords_alphabetised`.

`dsl::usage` is deleted. The "available commands:" fallback in
`render_usage_block` now formats entry words as `` `<word>` ``
directly (matching the `parse.token.keyword.*` catalog renders);
the per-keyword catalog wrappers will collapse in the next step
(ADR-0024 §cleanup-pass §F).

`parse_command` and `parse_tokens` slim down:
- `parse_command(input)` no longer pre-lexes — the walker scans
  source bytes directly.
- `parse_tokens` (internal-only `pub` for "future I3/I4 work")
  is removed; its body folded into `parse_command`.
- `unknown_command_error` reads the walker registry directly.

Touched modules also drop their `crate::dsl::lexer::lex` and
`crate::dsl::usage` imports: `app.rs`, `input_render.rs`,
`completion.rs`.

Tests: 852 passing, 0 failing, 1 ignored (down from 860 because
the 8 `dsl::usage::tests::*` tests are gone with the module).

claude@clouddev1 dca472f8a5 ADR-0024 Phase E: replay end-to-end
Migrate `replay <path>` to the walker. Shape is
Choice(StringLit, BarePath); the StringLit branch handles the
quoted form (with the existing `''` escape), and BarePath
handles the unquoted form.

Per ADR-0024's path-bearing UX change (already shipped for
import / export in Phase A), bare `replay` paths terminate at
the first whitespace byte. Paths with spaces require the
quoted form. The legacy `try_parse_replay_with_bare_path`
source-slice helper in dsl/parser.rs is removed; the
chumsky-side replay branch in command_parser stays declared
but unreachable until Phase F sweeps the chumsky path.

Tests:
- 7 new walker-specific tests for replay: bare relative path,
  bare absolute path, quoted with whitespace, quoted with
  escaped quote, case-insensitive keyword, missing-path
  error, empty-quoted-path parses to empty (runtime layer
  rejects).
- Total: 844 passed, 0 failed, 1 ignored (was 838 / 1).
- cargo clippy --all-targets -- -D warnings clean.

claude@clouddev1 c2accc2385 ADR-0024 Phase D: data commands at chumsky parity
Migrate the four data commands at four entry words: show
(show data / show table), insert, update, delete. Walker now
owns the entire command set introduced through ADR-0014.

Scope deviation from ADR-0024: full schema-aware value typing
via DynamicSubgrammar(column_value_list) is deferred. The
walker accepts any value at any position — matching the
existing chumsky parser's behaviour, where per-column type
checks happen at bind time. The DynamicSubgrammar Node
variant and WalkContext schema fields stay declared so the
infrastructure is in place when the schema cache plumbs
through parse_command (a future refinement). All existing
tests pass on the new shape.

Walker extensions:
- StringLit terminal — wired to the consume_string_literal
  helper that mirrors the legacy lexer's `''` escape handling.
  MatchedItem text carries the unescaped payload; span covers
  the surrounding quotes.
- Bridge: Incomplete error wording now appends `, found end
  of input` (matching the chumsky-side structural error
  contract that `structural_error_for_show_data_without_arg`
  asserts on).

Grammar:
- src/dsl/grammar/data.rs: SHOW (Choice of show_data /
  show_table), INSERT (three forms folded into a single shape
  via a Choice ordered to disambiguate Form B's `values`
  keyword from Forms A/C's `(`-prefixed content; the inner
  paren list is a Choice(VALUE_LITERAL, Ident{Columns}) with
  VALUE_LITERAL ordered first so `true`/`false`/`null` match
  their Word branch rather than the broader identifier catch-
  all), UPDATE (assignments + filter), DELETE (filter).
- VALUE_LITERAL = Choice(Word("null"), Word("true"),
  Word("false"), NumberLit, StringLit) — matches the chumsky
  `value_literal()`.
- WHERE_CLAUSE / FILTER_CLAUSE shared between update and
  delete.
- AST builders walk MatchedPath items in order, using role
  tags (`update_set_column`, `filter_column`,
  `insert_first_item`) to discriminate column references
  belonging to different shapes within the same command.

Tests:
- 13 new walker-specific tests covering all data forms:
  show data / show table, insert with each of three forms,
  insert with negative numbers, update with single + multiple
  assignments + where, update with --all-rows, delete with
  where, delete with --all-rows, update/delete without filter
  errors, replay still routes via chumsky.
- Total: 838 passed, 0 failed, 1 ignored (was 825 / 1).
- cargo clippy --all-targets -- -D warnings clean.
