Interim handoff. ADR-0028 (query plans / explain) is started:
step 1 (the styled-output-line mechanism, 03d8a09) is done and
committed. handoff-20 carries the full validated build plan
for steps 2-5 with file:line anchors and three implementation
gotchas (the const/static Subgrammar wrinkle, build_show's
positional dispatch, and why steps 2+3 must land as one
commit) so a fresh session implements them without
re-exploring.
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.
handoff-19 §2 now records the two bugs as fixed (was "queued
next"): the optional trailing-flag completion fix (f239ca5)
and the --resume temp-project pointer fix (3a40ae2). §5 drops
them from "what's next" — ADR-0028 is now the natural next
pick. State/§6 updated to 10 commits and 1131 tests;
requirements.md test baseline → 1131.
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.
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.
ADR-0027 gains a "Follow-up" section recording the completed
§2 highlight + hint wiring and precise per-literal WARNING
spans; the three stale As-built bullets point at it.
requirements.md test baseline → 1125 and the S6 entry notes
the completion + Amendment 1. handoff-19 records the run and
queues the two deferred manual-testing bugs (add 1:n
relationship completion/usage hint; --resume / last_project)
as the next session's first work.
The validity-indicator debounce was two locals in the event
loop (indicator_pending + app.input_indicator) with no unit
coverage — ADR-0027's as-built notes flag it as untested async
glue. The decision logic is now an IndicatorDebounce struct:
note_event (a keystroke hides + arms; non-key events leave it
be), settle (the quiet window elapsed → show the verdict +
disarm), is_armed (drives the recv timeout), visible (mirrored
into app.input_indicator for the renderer).
No behaviour change — the tokio timer and terminal stay in the
loop. 7 unit tests cover the debounce contract: the keystroke /
settle cycle, clean verdicts, and that a background event
mid-typing does not cancel the owed recompute. 1125 passing,
clippy clean.
ambient_hint now reads the walker's schema-aware diagnostics.
input_diagnostics is non-empty only for a command that
structurally parses — so a non-empty result means "complete
and submittable, but wrong or dubious". That is checked early
(right after the Tab-cycle memo), ahead of slot hints and
completions: a command that parses but is flawed no longer
gets the misleading "Submit with Enter" prose, it gets the
diagnostic's why. pick_hint_diagnostic prefers the diagnostic
under the cursor, else the most severe.
The cursor-local invalid-ident hint is kept for genuinely
incomplete commands (no Match → no diagnostics).
5 ambient_hint tests (unknown table, type-mismatch over
submit-prose, LIKE-numeric, clean command still submittable,
cursor-following). The complex_and_or matrix cell referenced a
non-existent column `t`; fixed to a real column so it tests a
valid expression as intended. 1118 passing, clippy clean.
render_input_runs now overlays the walker's schema-aware
diagnostics: an unknown table/column ERROR is recoloured
tok_error, an expression WARNING (type mismatch, = NULL, LIKE
on a numeric column) recoloured theme.warning. New overlay_span
covers a token's whole byte range (overlay_error only hits the
run at a single byte). New walker::input_diagnostics is the
shared entry point.
The overlay is global — every flagged token is coloured
wherever it sits, not only under the cursor — which is exactly
ADR-0027's motivation. The existing cursor-local invalid-ident
overlay is kept (it covers in-progress idents diagnostics do
not); the two are additive and idempotent.
5 input_render tests (unknown table/column, type-mismatch
literal precise, LIKE-on-numeric, clean command). 1113 passing,
clippy clean.
LIKE is a text-pattern match; against a numeric column (int,
real, decimal, serial) it runs but is almost never intended.
predicate_warnings now emits a WARNING for it, spanned at the
target column. New Type::is_numeric; catalog key
diagnostic.like_numeric; ADR-0027 gains "Amendment 1" and the
adr/README index line is updated per the index-upkeep rule.
bool and the text-/blob-backed types are deliberately not
flagged — see the amendment for the rationale.
3 walker tests (int, decimal NOT LIKE, text-column clean).
1108 passing, clippy clean.
Expression WARNING diagnostics (type mismatch, = NULL) carried
a coarse span — the whole WHERE clause, from the `where`
keyword to end of input. They now span exactly the offending
literal operand, read from the Operand source span added in the
previous commit. predicate_warnings derives the span per
warning; pair_type_mismatch returns (message, literal-span);
the dead where_clause_span helper is removed.
5 walker tests assert the spans cover exactly the literal /
identifier (type mismatch, = NULL, BETWEEN bounds, IN item,
unknown-column ERROR). 1105 passing, clippy clean.
Each WHERE-expression Operand now records the byte span of the
terminal it was built from — the precise per-literal highlight
target for an expression WARNING (finishing ADR-0027 §2's
highlight/hint wiring). parse_operand captures MatchedItem::span;
the RowFilter::eq convenience constructor uses Operand::NO_SPAN.
PartialEq is hand-written to ignore the span — it is editor
metadata, so Command equality stays whitespace- and
position-independent, which the Expr test corpus relies on.
No behaviour change; 1100 tests still pass, clippy clean.
The multi-form usage-template fix (151ed08) and the reviewed
`add index` syntax decision (kept as-is), so the next agent
does not re-flag a settled question.
A parse error in `add index …` showed the `add column` usage:
`add` and `drop` are multi-form commands, and both the
ambient hint and the submit-time usage block picked the
first-listed form unconditionally.
New `grammar::usage_key_for_input` disambiguates by the form
word after the entry keyword — `column` / `index` / `table` /
`relationship`, or the leading digit of `add 1:n …`. The
ambient hint now shows that one form; `render_usage_block`
shows the committed form's usage and falls back to the whole
family only for a bare `add` / `drop` with no form chosen.
Sweep: input_verdict tests confirm the schema-existence check
fires across the identifier-taking commands — unknown table
on drop / show / add column, unknown column on drop column /
update — and that known references stay clean. The Step B
check is grammar-generic, so this is verification + coverage
rather than new code.
Docs: requirements.md S6 -> [x], baseline 1096; CLAUDE.md
deferred list reconciled (C5a and S6 are done — removed);
ADR-0026's as-built note updated (step 5 shipped via
ADR-0027); ADR-0027 gains an As-built notes section
recording the post-walk diagnostics realization, the
pre-rendered message, the timeout-based debounce, coarse
WARNING spans, and the deferred highlight/hint wiring.
The event loop now time-boxes `recv` while an indicator
recompute is owed: every keystroke hides the indicator and
arms an `INDICATOR_DEBOUNCE` (1s) window; once typing pauses
that long the runtime computes `App::input_validity_verdict`
and shows `[ERR]` / `[WRN]`. An idle session (nothing owed)
still blocks plainly on `recv` — no wake-ups.
`update()` stays pure — the debounce timer lives in the
runtime; `App` only holds the resulting `input_indicator`
state, which the runtime clears on a keystroke and sets when
the quiet interval elapses.
`App::input_validity_verdict` is tested directly (a
simple-mode verdict, and silence in advanced mode / the `:`
one-shot); the debounce timing itself is runtime-loop glue,
covered at the integration level.
Adds the `[ERR]` / `[WRN]` validity indicator to the input
row. `App` gains `input_indicator: Option<Severity>` (the
runtime owns its timing — step E) and a pure
`input_validity_verdict()` query that runs `input_verdict`
in simple mode only (advanced mode is raw SQL, ADR-0027 §7).
`render_input_panel` reserves the rightmost six columns of
the input row unconditionally (ADR-0027 §4) — a five-column
label plus a one-column gap — so the typed command never
shifts sideways when the indicator appears or hides. The
label renders only when `input_indicator` is set: `[ERR]` in
`theme.error`, `[WRN]` in the new amber `theme.warning`
(defined for both light and dark themes).
The indicator is not yet wired live — `input_indicator`
stays `None` until the debounce lands (step E). Covered by a
render test and the theme contrast test; the input-panel
snapshot is updated for the six-column reservation.
Type-mismatched comparisons and `= NULL` / `!= NULL` in a
WHERE expression now yield WARNING diagnostics — the command
still parses and runs (the ADR-0026 §7 permissive posture is
unchanged), but the validity indicator can flag it before
submission.
Computed post-walk from the built command's `Expr` against
the table's column types: a Compare / Between / In with a
column operand and a non-null literal whose type the column
cannot hold, or a Compare with `=` / `!=` against NULL. New
catalog keys `diagnostic.type_mismatch` / `diagnostic.eq_null`.
This is ADR-0026's deferred step 5, folded into ADR-0027's
diagnostics-severity model as the user requested.
`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`.
Adds `Severity` (Error / Warning, ordered so Error > Warning)
and `Diagnostic { severity, span, message }` in
`walker::outcome`, plus a `diagnostics` field on `WalkResult`
— the schema-aware findings layered on a structurally-valid
parse (ADR-0027 §2).
`input_verdict(source, schema)` is the validity-indicator
entry point: `None` when the input would run clean (and for
empty input), `Some(Error)` for a parse failure or unknown
command, `Some(Warning)` for the ADR-0026 expression flags.
The verdict is the highest severity across the parse outcome
and the diagnostics set.
`diagnostics` is empty at this step — the schema-existence
(ERROR) and expression (WARNING) passes that fill it land
next. Covered by `input_verdict` unit tests.
Adds tests/typing_surface/where_expression.rs — 9 matrix
cells for the complex WHERE / show-data limit typing surface:
operator candidates after an operand, AND / OR after a
predicate, NOT, BETWEEN / IN bounds, and `show data`
where / limit.
Writing the cells surfaced a grammar bug. `predicate_tail`'s
`[NOT] negatable` branch started with `Optional(not)`, and an
Optional-first `Seq` always "commits" — so on an incomplete
input the walker's `Choice` returned that branch's
`Incomplete` early and discarded every sibling branch's
expected set, dropping `is` and the comparison operators from
completion after a column. Fixed by splitting it into
explicit `NOT negatable` and bare `negatable` branches — no
`predicate_tail` branch starts with an `Optional` now. The
matched terminal sequence is unchanged, so `build_expr` is
untouched.
Docs: ADR-0026 gains an "As-built notes" section recording
the option-1 builder realization, its two deviations from the
§3 sketch, and the deferral of §7 diagnostic flagging to
ADR-0027. requirements.md C5a -> [x] (steps 1-4) with the
test baseline refreshed to 1079; CLAUDE.md's deferred list
reconciled (C5a implemented; the QA1/QA2 note now points at
ADR-0028).
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.
The stratified WHERE-expression grammar — or / and / not /
bool_primary / predicate tiers as named `static` Node
fragments, recursing through `Subgrammar`. Covers the six
comparison operators (`<>` and `!=` both NotEq), AND / OR /
NOT, parentheses, LIKE / IN / BETWEEN with optional infix NOT,
and IS [NOT] NULL. `predicate_tail` factors the shared operand
prefix and the infix NOT so the Choice branches discriminate
on a cleanly-failing first token.
New recursive Expr / Predicate / Operand / CompareOp AST in
dsl::command. `build_expr` folds the flat matched-terminal
slice into an Expr — a deterministic recursive descent
mirroring the grammar tiers, with single-child tiers
collapsing. Per ADR-0026 §3 option 1: the walker stays a pure
structural matcher; Expr is assembled only in this
submit-time fold.
Fragment + builder are unit-tested standalone (walk against
&OR_EXPR, then build_expr); not yet wired into any command.
New `Node::Subgrammar(&'static Node)` variant lets a named
static grammar fragment recurse through a reference — `Seq` /
`Choice` embed children by value and cannot close a cycle, but
a `&'static Node` can point back at an enclosing fragment. This
is the mechanism the stratified WHERE-expression grammar
(ADR-0026 §2) recurses through.
The walker counts active Subgrammar frames in
`WalkContext::subgrammar_depth` and refuses past
`MAX_SUBGRAMMAR_DEPTH` (64), surfacing a friendly
`parse.custom.expression_too_deep` error instead of a stack
overflow. Depth is saved/restored per frame so a
speculatively-walked-then-rolled-back Choice branch leaves no
residue.
No grammar references the node yet; covered by walker unit
tests with a small recursive `( x )` test grammar.
`create table … with pk` parsed column types as `name:type`,
while `add column` uses `name(type)`. Unify on the parens
form so column-type syntax is consistent across the DSL:
create table T with pk id(serial), name(text)
Only `COL_SPEC` changes (`:` → `( … )`); `build_create_table`
reads columns by role, so it is unaffected. The `:` that
separates table from column in `add column` / `drop column`
is unchanged. Sweeps the test suite, the typing-surface
matrix (two `after_colon` cells renamed to `after_paren`,
4 snapshots regenerated), the friendly catalog's usage
templates, ADR-0009's example, and requirements.md.
1039 passing / 0 failing / 1 ignored; clippy clean.
The QA1/QA2 design: an `explain` prefix command over
`show data` / `update` / `delete` that runs
EXPLAIN QUERY PLAN (without executing the statement) and
renders the result as an annotated tree. Plan steps keep
the engine's own wording; an annotation taxonomy marks
full scans, index use, and the automatic-index "you
should add an index here" case. Introduces a general
styled-output-line mechanism — an OutputLine may carry
per-span styling — realising the per-span theming
ADR-0016 deferred; the plan renderer is its first
consumer. The explained SQL is shown above the tree as
standard, copy-pasteable SQL.

A debounced `[ERR]` / `[WRN]` marker at the right edge of
the input row, summarising — before submit — whether the
current command would run. Backed by a small

The C5a design: a stratified, recursive WHERE-expression
grammar (AND/OR/NOT, comparisons, LIKE, IS NULL, IN,
BETWEEN) for update / delete / show-data filters; show
data gains optional `where` and `limit`. Adds the
`Subgrammar` reference-following grammar node and a

`push_history` skipped its `history_cursor` / `history_draft`
reset on the consecutive-duplicate early-return path. Recalling
a command with Up and re-submitting it unchanged left the cursor
stranded at that entry, so the next Up stepped backwards from
there instead of restarting at the newest entry.
Move the reset ahead of the early-return guards. Adds a Tier-1
regression test driving the recall/resubmit keystroke sequence.
Implement ADR-0025 — indexes as a DSL DDL feature.
- Grammar: `add index [as <name>] on <T> (<cols>)`, `drop index
<name>` / `drop index on <T> (<cols>)`, plus a `--cascade`
flag on `drop column`.
- db.rs: index operations over the engine's native index
catalog (no metadata table). The rebuild-table primitive now
captures and recreates indexes, so `change column` and the
relationship operations no longer silently drop them.
- `drop column` refuses an indexed column unless `--cascade`,
which drops the covering indexes and reports each.
- Persistence: additive `indexes:` list in `project.yaml`
(version unchanged); round-trips through rebuild/export/import.
- Display: an `Indexes:` section in the structure view and a
nested tables/indexes items panel (S2).
Reconciles requirements.md (C3 index portion, S2 satisfied)
and CLAUDE.md. 1038 tests passing (+31), clippy clean.
ADR-0024 audited as fully implemented. Amend the ADR with a "Phase F
minimal" implementation note (parser.rs retained as the router +
ParseError home) and update the README index line to match.
Reconcile docs/requirements.md against handoffs 10-14: refresh the
test baseline (449 -> 1006), mark U4 (replay) satisfied, correct the
A1 / H1a / H3 progress notes.
Amend handoff-14: §3 flagged items both resolved (ranker kept,
CommandNode.hint_mode removed); §4 rewritten as a concrete next-work
pointer at the reconciled requirements.md.
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.
Every CommandNode declared a help_id that nothing read; the in-app
`help` body was a single hand-kept catalog block that drifted from
the command set (handoff-12 §2.1).
note_help now iterates the command REGISTRY and translates each
CommandNode's help_id (`help.<id>`), framed by help.intro /
help.dsl_section / help.types_reference. A newly-registered command
appears in `help` automatically — no edit to note_help or a hand-kept
list. Added 20 per-command help entries plus the 3 framing entries;
removed help.in_app_body.
Per-command entries use block scalars: a libyml 0.0.5 scanner bug
panics on long internal space runs in double-quoted scalars, and the
entries are space-aligned.
run_replay parsed each line with the schemaless parse_command, so
Phase D typed-slot rejections (wrong-count value lists, wrong-type
column values) fired only at bind time during replay — inconsistent
with the interactive path (handoff-12 §2.1).
run_replay now re-snapshots the schema per line (the schema mutates
as replayed create-table / add-column commands run) and parses with
parse_command_with_schema. Extracted build_schema_cache, shared with
the interactive refresh_schema_cache.
Added a replay integration test asserting a typed-slot violation is
caught at parse time (through the replay.error_parse wrapper).
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.
Node::DynamicSubgrammar factories build a Node from the WalkContext and
must Box::leak it (the Node enum's combinator children are &'static).
Leaking per walk grew unbounded under per-keystroke completion
(handoff-12 §2.1).
resolve_dynamic now memoizes on the schema state a factory reads
(table columns, current column, user-listed columns) keyed by factory
fn-pointer. Each distinct value-list shape leaks exactly once — total
leak bounded by distinct (schema × form) combinations, not keystroke
count. TableColumn gains Hash for the cache key.
The handoff's original arena sketch needed a lifetime-generic Node
(major refactor); memoization gets the same bound without it.
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.
Handoff-12 §2.2: Form B `insert into T values (…)` silently skips
auto-generated columns from the value list, so a user who wants to
set a serial/shortid column explicitly could only discover Form A by
reading help. Now the hint at the first Form B value slot appends a
note naming the skipped column(s) and pointing at the explicit-column
form.
hint_resolution_at_input derives the skipped columns from the
post-walk WalkContext (Form B = no user_listed_columns + table has
serial/shortid columns) and reports them on HintResolution; the note
fires only at the first slot so it doesn't repeat at every comma.
ambient_hint composes it onto the per-column prose.
8 tests covering completion-candidate order: connective keywords in
reading order (`to`/`from`/`in` before `table`), and command-part
keywords before schema identifiers. The ordering already held via
declaration-order preservation + keywords-first sectioning in
candidates_at_cursor; nothing pinned it until now, so a future
grammar or sort change could silently break the hint panel's
left-to-right reading.
The 5 structural-class entries (identifier/number/string_literal/flag/
end_of_input) and 3 lex-error entries (bad_flag/unknown_char/
unterminated_string) were unreachable: ADR-0024 Phase F made the
walker render keyword wording verbatim and the lex errors never
surface through today's walker. Handoff-12 §2.1 kept them as a
conservative call; removed now per user request. Re-adding is cheap
if a future need arises.
55 tests covering create table, drop column, drop relationship
(endpoints + by-name), add relationship, rename/change column, and
all app-lifecycle commands. The drop-column and relationship tests
drove the §2.2 writes_table fix in the previous commit.
Documents one UX wrinkle as a flagged finding: partial entry words
(`qu`) classify as DefiniteErrorAt — same as unknown commands —
because the walker only engages on a complete entry word.
859 baseline -> 989 passing; 1 ignored (pre-existing doc-test).
Handoff-12 §2.2: the DDL TABLE_NAME_EXISTING slot and the
relationship-endpoint table idents didn't set writes_table, so
column-name slots downstream (drop/rename/change column; relationship
qualified columns) couldn't narrow to the active table — candidates
leaked from every table. Set writes_table: true on TABLE_NAME_EXISTING
and on DR_PARENT/DR_CHILD/AR_PARENT/AR_CHILD table idents. The
deliberately-documenting completion test now asserts per-table
narrowing.
34 new tests covering:
- Form C bare-value-list (happy path + Form-A-recovery + type-unaware grammar limitation per handoff §2.2)
- update with WHERE (column-narrowing invariant per handoff §1 bug E1; typed-slot prose for assignments and where filters)
- update --all-rows (filter-clause requirement per ADR-0014)
- delete with WHERE (column-narrowing; typed-slot prose for where filters)
- delete --all-rows
859 baseline -> 931 passing. No bugs surfaced — the data-mutation
command family was already well-shaped post-Phase-D.
12 tests across schema_serial_pk / text_pk / multi_table / every_type.
Pins (a) Form B skips auto-gen columns from the slot list (regression
for handoff-12 §B fix); (b) wrong-count value lists are now flagged
at typing time, not only at submit (the previous commit's fix); and
(c) per-type slot prose advances correctly through every Type variant.
