claude@clouddev1 5a37437055 fix(hint): correct H2 corpus errors + add parse guard (handoff-71)
Semantic verification pass over the tier-3 `hint` corpus (ADR-0053).
Four content errors corrected in src/friendly/strings/en-US.yaml:

- cmd.create_table: the example `with pk id(serial), name(text),
  email(text)` declares a 3-column COMPOUND primary key, not a PK
  plus regular columns (every `with pk` column is a key member,
  ADR-0005). Rewritten to a single-column PK + `add column` for the
  rest; what/concept aligned.
- cmd.save: `save as my-shop` does not parse — `save as` takes no
  inline name, it opens a path-entry prompt. Example -> `save as`;
  what no longer implies inline naming; added a temp-vs-named concept.
- cmd.import: target `shop-copy` does not parse — the `as <target>`
  slot is a NewName ident that rejects hyphens. -> `shop_copy`.
- err.foreign_key.child_side: dropped the bogus `on delete set
  null/cascade` remedy — that governs the parent direction; a
  child-side violation is fixed by inserting the parent first
  (matches the tier-1 hint).

Adds every_cmd_hint_example_parses_in_its_mode — a catalog-driven
guard that parses every hint.cmd.* example in its taught mode,
backstopping syntactic drift (it caught the save and import errors).
Registers the new hint.cmd.save.concept key.

docs: drop two stale "deferred" entries from CLAUDE.md — project
storage (export/import, --resume, input history, migration scaffold)
and m:n convenience (C4) are all implemented (ADR-0015/0045); record
the verification pass on requirements.md H2.

claude@clouddev1 447112b17f feat(hint): H2 Phase D — coverage gate, F1 strip, status flips (ADR-0053)
Completes H2:
- comprehensiveness coverage tests: every REGISTRY command form has a
  hint_id resolving to a hint.cmd.* block, and every runtime error class
  resolves to a hint.err.* block (enforces ADR-0053 D6)
- ADR-0051 keybinding strip advertises F1 in the editing (leads) and
  default states; +shortcut.hint label; 12 full-panel snapshots
  re-accepted (status-bar line only)
- flip ADR-0053 -> implemented, requirements H2 + A1 -> [x], README

2498 pass / 1 ignored, clippy clean.

claude@clouddev1 984bc30256 docs: record CI branch work — D1/D2 done, TT5 partial, handoff 70
requirements.md: D1 (all six cross-platform binaries) and D2 (no-runtime-
deps, per-platform) done; D3 noted (binaries shipped, package managers
pending); TT5 partial (gate + macOS test live; Windows build-only; Tier-4
unwired). CLAUDE.md: add the CI/release decision (-> docs/ci/adr) + update
the deferred list. Adds handoff 70 summarising the pipeline + follow-ups

claude@clouddev1 66c8bdaa65 feat(input): readline keymap — Esc-clear + Ctrl-A/E/W/K/U (#29)
Implement the deferred I1b readline shortcuts in the command input
field (ADR-0049, closing issue #29):

  Esc      clear a partly-typed command (only when no completion memo)
  Ctrl-A   cursor to line start (Home alias)
  Ctrl-E   cursor to line end (End alias)
  Ctrl-W   delete the previous word (readline-style, UTF-8 safe)
  Ctrl-K   kill to end of line
  Ctrl-U   kill to start of line

Esc precedence is preserved: a live Tab-completion memo still wins
(Esc undoes the completion first, ADR-0022); Esc clears only when no
memo is alive. While a sidebar panel is focused (Ctrl-O), Esc exits
navigation mode upstream and never clears the input draft. Cursor-only
keys leave history navigation intact like Home/End; buffer-mutating
keys end it like Backspace.

New helpers clear_input / delete_prev_word / kill_to_end /
kill_to_start in src/app.rs. 22 new Tier-1 tests (2458 pass / 0 fail
/ 0 skip, clippy clean). ADR-0049 amends ADR-0046's OOS list;
requirements.md I1b marked done.

claude@clouddev1 deb0948d6c feat(seed): year-as-int + conventional choice-set heuristics (#33, #34)
Two additive D7 catalogue rules, surfaced while writing the website seed
docs. No change to the type fallback, executor, or grammar.

#33 — year-like int columns. `published`/`birth_year` were just `int`, so
they fell to the unbounded int path and produced nonsense (`9419`). Add an
int-gated year rule (after the quantity rule, so `year_count` stays a
count): `year`/`*_year`/`published`/`founded` -> a bounded 1950-2025 year
(new `YearRecent`), or the dob-style birth window 1945-2007 for
`birth`/`born`/`dob` (new `YearBirth`). Plain int; not added to the D9
named-generator vocabulary.

#34 — conventional choice sets. A few enum-ish names have a near-canonical
small set that reads far better than lorem text. Add a type-gated PickFrom
lookup (reusing the existing generator): priority/prio, severity,
rating/stars. `status` is deliberately excluded (values too
domain-specific) and keeps the D12 advisory; a user IN-CHECK still wins.
`priority` leaves ENUM_TOKENS.

ADR-0048 Amendment 1; +8 tests (incl. a column-fill integration test that
also closes a pre-existing gap on that path).

claude@clouddev1 0af7f56821 docs: ADR-0048 — seed fake-data generation command (SD1/SD2, A1)
Dedicated `seed` command: realistic, name-aware fake data via the
`fake` crate + a type-gated heuristic catalogue, table-context name
disambiguation, a hand-rolled product generator, bounded dates, an
identifier-uniqueness rule, a quoted `set` override clause (value /
list / generator / range), `--seed` reproducibility, FK sampling
(empty-parent error, junction distinct combinations), CHECK
derive-or-friendly-fail, undo as one batch step, replay as a
data-write, capped auto-show, and an enum/CHECK advisory.

Design settled across an extended user fork dialogue, then hardened
by a /runda DA pass that found six blockers (undo, replay, set
quoting, CHECK handling, advisory phasing, auto-show flood) — all
folded in, genuine forks re-escalated and user-resolved.

Takes up SD2 ([~]->[ ]); SD1 implementation in progress.

claude@clouddev1 4d0ae776cc docs: withdraw multi-tab output from scope (S3/V2 → satisfied)
The trailing "multiple tabs" clause of S3 and V2 is dropped from
tracked scope by user decision. The output pane is settling on the
single scrollable V4 journal model rather than switchable result
tabs, so both items are now fully satisfied (the table view and
single-element visualisation were already built). V4 noted as the
sole tracked direction for evolving the output pane. A future
return to tabbed output would be a fresh requirement.

No ADR touched: multi-tab output never had a deciding ADR.

claude@clouddev1 93266b99c9 docs: ADR-0046 UI sidebar nav-mode + responsive input/hint (#20/#21/#23)
Accepted; implementation pending, phased A→B→C. Treats the three
coupled UI issues as one decision (shared width/height budget):

- #20 hint jumpiness: hint height becomes a function of terminal
  geometry, fixed between resizes, so it no longer shoves the
  input/output panels.
- #21 left column: kept but width-optional (hidden by default ≤90),
  with a new relationships sibling panel and a Ctrl-O navigation/focus
  mode (peek-reveal, expand-on-focus overlay, scroll).
- #23 long input: single-logical-line horizontal scroll plus a 2-row
  display when tall, preserving the ADR-0027 indicator reserve.

A pre-build /runda DA pass drove key corrections: Ctrl-B→Ctrl-O (Ctrl-B
is the tmux prefix), an additive SchemaCache.relationship_details field
(retyping would break completion), full nav-mode key disposition +
modal gate, and Tier-2 snapshot coverage. Reconciles requirements
S1 (evolved), S2 (overridden — separate relationships panel), and
S4 (corrected — the stale "keyboard-toggleable" hint claim is struck;
no toggle added).

Updates docs/adr/README.md index and docs/requirements.md S1/S2/S4.

claude@clouddev1 8bd43ccadf feat: create m:n relationship convenience command (C4, ADR-0045)
`create m:n relationship from <T1> to <T2> [as <name>]` generates a
junction table with one FK column per parent PK column ({table}_{pkcol},
typed via fk_target_type), a compound PK over them, and two CASCADE 1:n
relationships -- all in one do_create_table call = one undo step.
Auto-named {T1}_{T2} (optional `as`), both modes, compound-parent PKs
supported (ADR-0043). Self-referential m:n / PK-less parent / internal
junction name / name collision all refused.

Wired across every surface: grammar (separate CREATE_M2N node), worker
executor, runtime dispatch, completion ("m:n" composite), hints,
highlighting, help + usage catalog + disambiguator, and the advanced-mode
DSL->SQL teaching echo (render_create_m2n, round-trips as valid SQL).

Generalized/fixed framework assumptions the build + two /runda passes
surfaced (all behaviour-preserving for existing commands):
- simple-mode dispatch committed simple.first() unconditionally -> tries
  candidates, so `create table` no longer shadows `create m:n`.
- the completion continuation-merge was advanced-only -> runs in simple
  mode too when an entry word has >1 DSL form (gated simple_count>1).
- do_create_table now rejects internal `__rdbms_*` names (closes a
  pre-existing hole on the DSL create-table path too, not just m:n).
- usage disambiguator now recognizes the `m:n` opener.

Tests: 14 integration (tests/it/m2n.rs), 7 typing-surface matrix, echo /
highlight / usage / internal-name units. Closes C4.
2237 pass / 0 fail / 1 ignored. Clippy clean.

claude@clouddev1 0a7612efe2 feat: comprehensive logging across parser, app, persistence, runtime (X1)
Completes the X1 full sweep started in a8ad0c6 (db.rs). Closes X1 -> [x].

- persistence/mod.rs: debug! on every yaml/CSV/history write -- the
  silent-failure-prone disk paths (write_schema, write_table_data incl.
  the empty->delete branch, append_history/_failure).
- runtime.rs: debug! on execute_command_typed dispatch (one per executed
  command, complements the db.rs executor logs).
- app.rs: debug! on submit (route + submission mode), dispatch_app_command,
  and the ADR-0044 diagram-vs-prose render-mode choice.
- dsl/parser.rs: trace! on parse begin/outcome at the parse_command_inner
  choke point -- trace, not debug, because the live overlay/completion
  re-parse per keystroke (hot path).
- logging.rs: documented level discipline (error/warn/info/debug/trace) so
  the convention survives across sessions.

Levels verified end-to-end through the real worker thread + logging::init.
~75 -> 135 tracing sites total. Tests: 2207 pass / 0 fail / 1 ignored.
Clippy clean.

claude@clouddev1 0a343036d8 feat: compound-FK bus routing + complete V1 relationship visualization (ADR-0044)
Completes requirement V1. A compound (multi-column) FK now routes a
bus connector — each paired endpoint's stub merges into a shared
vertical channel that splits to the other side — plus an explicit
"(a, b) ▶ P.(x, y)" pairing line; the bus generalises the single-column
jog (reproducing it exactly, so prior snapshots are unchanged).
Self-referential FKs render as two same-named boxes.

- output_render.rs: gutter_seg routes all endpoint pairs via a
  junction() bus; pairing line for compound FKs; compound, self-ref,
  and compound-from-data (build_diagram_table glue) tests + snapshots
- compound_fk.rs: worker test that show_relationship carries both
  paired column lists into the diagram payload
- db.rs: document do_show_one's now-app-superseded relationship prose
  branch (retained as a worker-API/text fallback; could back a future
  non-visual display option, cf. ADR-0044 OOS-7)

Second /runda pass over the implementation: confirmed ADR-compliance,
UTF-8/byte-range safety, and edge-case routing. The ADR §3 last-resort
helper line was considered and rejected (vertical fallback + ratatui
truncation cover all realistic cases). ADR-0044 marked implemented;
requirements.md V1 -> [x].

Full suite 2207 pass / 0 fail / 1 ignored; clippy nursery clean.

claude@clouddev1 4752ba29a0 feat: compound-PK foreign-key references — grammar + tests (ADR-0043)
Multi-column FK parsing on both surfaces: DSL from P.(a, b) to
C.(x, y) (parenthesized endpoint; single bare form unchanged) and
SQL FOREIGN KEY (a, b) REFERENCES P(x, y) incl. bare-reference
auto-expand. consume_fk_reference + the table-level/ALTER FK
parsers collect column lists; the from P. completion now offers
( (snapshots updated). 12 integration tests in
tests/it/compound_fk.rs cover parse (both surfaces), engine-enforced
FK, arity + partial-PK + per-pair-type-mismatch refusal,
--create-fk per-column, save->rebuild round-trip, undo (one step),
and single-column preservation. Mark T3 [x]; ADR-0043 implemented.

claude@clouddev1 274e2b17b7 docs: ADR-0043 compound-PK foreign-key references (T3); accepted
Audit found single-column FK woven through ~15-20 sites; earns an
ADR. Decision: reference the parent's full compound PK, matched
positionally to an equal-length child list, per-pair type compat.
DSL `from P.(a,b) to C.(x,y)`; SQL `FOREIGN KEY (x,y) REFERENCES
P(a,b)` with bare-FK auto-expansion. Storage follows the existing
primary_key: [...] list convention (yaml columns: [a,b], uniform
JSON in unchanged metadata TEXT cols); back-compat not required,
so no migration. Also marks T3's verified scope.

claude@clouddev1 1d898adf00 feat: V5a show relationship/index <name> detail views
Fold the singular per-item forms into Command::ShowList { kind,
name: Option<String> } (name: Some = one item). Two grammar
branches reuse the relationship/index completion sources; worker
do_show_one renders a labelled detail block or a friendly
"No ... named X." line, reusing the V5 render path. Help +
parse-usage entries, two ADR-0042 near-miss rows, 5 integration
tests. Mark V5a [x] — V5's [<name>] clause now complete.

claude@clouddev1 757711f2bf feat: H3 help <command> per-command detail + general reference
HELP node takes an optional single-word topic (BarePath);
AppCommand::Help { topic }. note_help_topic renders the help
block(s) of every command sharing that entry word (so `help
create` covers both create forms), plus `help types` and a
friendly "no help for X" pointer for unknown topics. Full help
gains a detail-hint footer. Catalogued help.detail_hint /
help.unknown_topic; parse-error matrix updated (help now takes a
topic, so the near-miss is the multi-word case). 9 integration
tests in tests/it/help_command.rs. Mark H3 [x].
2026-06-07 13:32:18 +00:00
claude@clouddev1 8dec784080 feat: V5 show tables / relationships / indexes list commands
Add the list-all show family as one Command::ShowList { kind }
variant. A read-only worker show_list formats count-headed lists
(reusing do_list_tables / read_all_relationships /
read_table_indexes, so it never drifts from the items panel);
internal __rdbms_* tables excluded. Help + parse-usage entries
added; 10 integration tests in tests/it/show_list.rs.

Mark V5 [x]. Split the singular show relationship/index <name>
detail forms (the [<name>] half) into a new tracked V5a [ ] item
rather than leaving them as an untracked footnote.

claude@clouddev1 c305dc7282 docs: mark H1a done via the ADR-0042 systematic pass
requirements.md H1a → [x]: the per-command near-miss matrix (entry words,
missing clauses, committed multi-forms, both modes) plus the gap fixes
(G1 `1:n relationship`, G2 select projection gloss, G3 mode-aware usage
showing all valid forms, G4 `with` CTE template, CROSS JOIN ON teaching
message) close the systematic pass. The advanced-SQL items the survey
flagged (INSERT…SELECT count, RETURNING scope) were verified already
present. One low-priority residual is deferred by decision (submit-time
expression first-set at non-projection positions).

ADR-0042: record the pre-existing `SELECT *` arity caveat (INSERT…SELECT
with a star projection isn't expanded for pre-flight arity; engine
catches it at execution — adjacent to ADR-0019 §OOS-2).

claude@clouddev1 be7b078878 docs: mark H1 done — friendly DB-error layer is shipped
Verification found H1 (ADR-0019) fully implemented and tested: the
friendly::translate_error chokepoint is wired on the live failure path
(runtime + app + DbError::friendly_message), covers all five error
categories (UNIQUE, FOREIGN KEY both sides, NOT NULL, CHECK,
type-mismatch) with operation×kind×verbosity wording, the messages
verbosity command, and §6 row-pinpointing via runtime-resolved facts —
backed by 44 friendly unit tests + 12 full-stack friendly_enrichment
integration tests. The "partial / FK-only" notes were stale.

Mark requirements H1 done; fix the obsolete "diagnostic_table is
always None" comment in translate.rs (pinpointing landed in 431645a).
Remaining ADR-0019 scope (§9 i18n sweep, §OOS-2 advanced-SQL
sanitization, §OOS-3 messages persistence) stays deferred.

claude@clouddev1 d0c8f9d5d2 feat: copy the output panel to the system clipboard (#11)
New app-level `copy` / `copy all` / `copy last` command (ADR-0041).
Delivery is OSC 52 *and* a best-effort native write (arboard), always
both — OSC 52 acceptance is undetectable, so a true fallback can't be
built. Payload is the panel's plain text exactly as rendered (tags,
✓/✗, box-drawing), drift-locked to render_output_line. arboard added
--no-default-features (X11-only; OSC 52 covers Wayland).

Amends ADR-0003's command registry; requirements V6.

claude@clouddev1 4cd574b909 feat: persist & restore per-project input mode (#14)
The input mode always started in simple; a learner who quit in advanced
had to re-toggle every launch. Store the mode per-project in project.yaml
(project.mode:, optional, default simple) and restore it on every open.

Mode is live UI state, not schema: the worker stamps the current mode
into project.yaml on every write, so a later command rewrites the live
value rather than clobbering it — no db round-trip needed. The mode is
persisted on unload (quit + project switch) so the mode you leave a
project in is always what reopens; the `mode` command also persists
immediately. A switch saves the outgoing mode, then restores the
incoming project's stored mode.

New --mode simple|advanced CLI flag (precedence --mode > stored >
simple; combines with --resume). A teacher can ship a project that
opens in advanced mode and export it to students (the mode travels in
the zip).

claude@clouddev1 6d8c9eea36 feat: curated SQL function list — Tab completion (#15) + typing-time typo hint (#16)
Add src/dsl/sql_functions.rs (KNOWN_SQL_FUNCTIONS) as the shared source
of truth at sql_expr_ident slots:

- #15: offer the functions as Tab candidates under a new
  CandidateKind::Function + ninth Theme colour tok_function (blue,
  distinct from keyword/identifier/type).
- #16: restore the column-typo flag the #6 fix had dropped wholesale —
  invalid_ident_at_cursor now bails only when the partial prefix-matches
  a known function, else falls through to the schema-column check.

A column named like a function (e.g. `count`) is deduped (column wins).
`cast` is excluded — CAST(x AS type) is not a plain-call shape.
The no-validation-allowlist posture stands: the list drives completion +
the typo hint only, never parse-time acceptance.

Docs: ADR-0022 Amendment 6, ADR-0031 status note, README index,
requirements I3/I4 + refreshed test baseline.

claude@clouddev1 8311de44a8 feat: replace the [ok] summary line with a ✓/✗ echo marker
An audit of the command surface found the `[ok] <verb> <subject>`
summary line duplicated the echo line above it everywhere; its only
unique signal was success-vs-error. Retire it: a command's echo line
now resolves from `running: <input>` to `<input> ✓` / `<input> ✗`
on completion, and the symmetric `"<verb> <subject>" failed:` prefix
is dropped (only the reason remains). Content lines (row counts,
structure, plan tree, teaching echo) are unchanged.

Echo lines carry an EchoStatus; executed commands push Pending and
resolve the oldest-pending echo on their result event (FIFO worker —
correct under interleaving). Parse-time and pre-flight rejections are
not executed and keep their running: + caret rendering. App-command
[ok] lines (rebuild/export/replay) are payload-bearing and untouched.

claude@clouddev1 f62cccec55 feat: support explain over advanced-mode SQL queries
explain now wraps the advanced SQL commands — select, with (CTE),
insert, update, delete — in addition to the DSL show data/update/
delete it already covered, rendering through the same plan tree
(ADR-0039, closing the ADR-0030 OOS-2 gap).

Implemented as a second Advanced `explain` CommandNode under the
shared entry word, reusing the established shared-word dispatch
(SQL-first, DSL-fallback) rather than new grammar machinery.
build_explain_sql slices the inner SQL off the source and reuses the
existing SQL builders; do_explain_plan runs EXPLAIN QUERY PLAN over
the carried text verbatim (never executes, so safe for destructive
verbs). Advanced explain update/delete now route through SQL with an
identical plan; DSL-explain tests pinned to simple mode. Help and
usage text now list the advanced explain forms.

claude@clouddev1 5ea69dbc08 fix: widen undo dialog and polish its summary line
The undo/redo confirmation dialog capped at 60 columns and wrapped
even a short insert on wide terminals, showed a lowercase "snapshot
taken", a raw ISO-8601 timestamp, and lowercase yes/no labels.

Grow the dialog to fit its longest line (bounded 34–100), capitalise
Snapshot/Yes/No, and render the snapshot timestamp in local time,
human-formatted (24 May 2026, 11:00) via a new chrono dependency
(clock feature only; English month names). Yes/No capitalisation also
applies to the rebuild-confirm dialog.

Both Node::Ident and Word carried a highlight_override field, and
both were dead — the walker driver discarded the Ident's and
walk_word hardcoded Keyword. So column types (int, serial, …)
rendered identically to table/column names.

Wire both overrides through, and add a dedicated HighlightClass::Type
with its own theme colour (tok_type), distinct from keyword-purple
and identifier-teal. The three type Ident slots opt in, so canonical
types and the advanced-mode single-word SQL aliases (float, varchar,
…) render as types; the two-word `double precision` alias opts in via
a new Word::type_keyword constructor. ADR-0022 Amendment 4.

claude@clouddev1 10e5197c19 feat: bring simple-mode insert arity diagnostics to parity with advanced
A wrong-count simple-mode insert now shows the friendly per-column arity
message at typing time (instead of a bare "expected `,`/`)`") and is
blocked from dispatch at submit — unifying simple and advanced mode onto
the one ADR-0027 model (structural parse + ERROR diagnostic), where they
had diverged.

Grammar: a simple-mode-only arity gate (dsl_insert_value_list) routes a
wrong-count DSL insert tuple to the type-blind fallback so it matches
structurally and the per-tuple arity diagnostic fires. The gate is gated
to simple mode, so advanced behaviour is unchanged. count_tuple_values
and the target-column selection (insert_target_columns) are now shared
by both grammars.

Diagnostic: dml_insert_arity_diagnostics is mode-aware — advanced Form B
expects all columns; simple Form B/C expects the user-fillable columns
(serial/shortid auto-fill). It counts the DSL Form A role and scans the
keyword-less Form C tuple. New catalog keys name the fillable/auto split
and the all-auto-table case.

Submit: a wrong-count DSL insert now parses Ok + carries the ERROR
diagnostic, so a unified Ok-arm pre-flight (dsl_insert_count_mismatch_notes)
blocks dispatch and teaches; the previous Err-arm note retires.
advanced_alternative_note's gate now reads the validity verdict so it
still fires for the parse-Ok-with-error shape.

claude@clouddev1 fa5d0dc6da fix: insert VALUES between-values hint points at comma not close-paren
The ambient-hint fallback in ambient_hint_core_in_mode parsed
schemalessly, so the type-blind grammar closed an `insert … values
(…)` tuple after the first value and the "Next:" hint pointed at `)`.
With a schema available the walk knows the remaining columns and the
correct next token is `,`. Parse the fallback with the schema cache so
the expected-token prose matches the rest of the (already
schema-aware) hint ladder.

Also corrects wrong-arity closed tuples where the schemaless parse
accepted the input and the hint said "submit with Enter" for a command
the schema-aware parse rejects — the hint now surfaces the accurate
error. Three typing-surface snapshots updated to match.

Docs: ADR-0022 Amendment 3 (+ README index) records the schema-aware
fallback; requirements.md H1a cites the hint-accuracy improvement.

claude@clouddev1 c12ed1da9a fix: INSERT Form B value-count UX (ADR-0033 Amendment 5)
Three layered fixes for advanced/simple-mode positional INSERT
value-count mismatches (e.g. `insert into T values (...)` with the
wrong number of values for T's column count), plus ADR-0033
Amendment 5 recording the gate refinement.

Walker diagnostic (dml_insert_arity_diagnostics): the function's own
doc-comment recorded the no-column-list (Form B) case as deferred.
This commit closes that gap. Form B mismatches now emit a new
diagnostic.insert_arity_mismatch_form_b ERROR per offending tuple,
keyed off the target table's column count from the schema cache. The
[ERR] validity indicator (ADR-0027) lights up at typing time for the
reported scenario, no longer needing a submit.

Cross-mode pointer gate (advanced_alternative_note): refactored from
a hand-rolled Form B count check to a single input_verdict_in_mode(
input, schema, Mode::Advanced) call. The pointer fires only when the
verdict is None — the ADR-0027 sense of "valid". Any future static
check added to the verdict pipeline participates automatically; no
per-feature maintenance.

Teaching notes for the value-count cases users can hit before the
indicator turns red:
  - simple-mode submit: insert.form_b_extra_values_note covers under-,
    in-window, and over-supply against the Form B contract; suppressed
    when the cross-mode pointer fires (to avoid parallel advice).
  - advanced-mode dispatch pre-flight:
    insert.form_b_positional_count_mismatch_note catches a submitted
    mismatch with a teaching message before the engine produces its
    raw NOT-NULL / type error.

The advanced_mode.also_valid_sql pointer wording was reworked to
"trying to write SQL? switch with `mode advanced`, or prefix `:` to
run once". One insta snapshot regenerated.

ADR-0033 Amendment 5 records the gate change: Amendment 3's "would
parse in advanced mode" now reads as "valid in advanced mode" in the
explicit verdict-is-None sense, with the precise definition spelled
out so future readers can't drift back to the syntactic-only reading.
ADR-0000 index entry updated; docs/requirements.md H1a citation added
listing the three new pedagogical strings.

Tests added (8): four walker arity tests (under-supply, over-supply,
match, unknown-table); two app-level teaching-note tests for the
sibling cases (under-supply, over-supply beyond total); one pointer-
gate unit test pinning the bug-case suppression; one gate-precedence
test ensuring only one advice line per error. Existing
simple_mode_submit_of_sql_construct_appends_advanced_pointer updated
to use a known schema (the new validity gate requires it).

Full suite: 2031 passed, 0 failed, 0 unexpected skips. Clippy clean.

claude@clouddev1 5cb105b74b docs(adr): /runda DA cleanup — reflect Phases 1-3 done, pin Bucket C
Surfaces from a Devil's-Advocate audit of the DSL → SQL teaching echo
(ADR-0038) after Phases 1-3 landed: three doc-drift bugs introduced
by the earlier handoff-47 / ADR-promotion commits — requirements.md
M4 and both ADR-0038 README index entry + Status block still said
"Phase 2 / Phase 3 remain," but `275c726` and `e6ad1ae` shipped them.
Updated to reflect actual state: Buckets A + B complete plus the
category-3 prose; only the §4 styled-runs polish remains. ADR-0037's
README entry also touched to note all four shipping commits of its
consumer.

Plus a missing test slice the DA flagged: explicit no-echo coverage
for the Bucket C cases that flow through command_to_sql's catch-all
(show table, explain, replay, every Command::App variant). The
contract — ADR-0030 §10 / ADR-0038 §7 Bucket C — forbids echoes for
these; a future renderer arm added at the wrong place could silently
leak one. The new bucket_c_no_echo_commands_all_return_none pins
that.

Tests: 2015 passed / 0 failed / 1 ignored (pre-existing); clippy
clean. Nothing to escalate.

claude@clouddev1 2bcc55f939 docs: reconcile requirements/CLAUDE.md with shipped reality (high-confidence)
Flip stale Phase-1 checkboxes whose capability is clearly delivered:
M1/M2/M3 (modes), Q1/Q2 (SQL subset — shipped via the unified walker, not
sqlparser-rs), TT1/TT2/TT3 (test tiers 1–3) → [x]; TT4 (PTY e2e, critical
flows only) → [~].

Fix stale CLAUDE.md claims: the stack no longer uses chumsky (DSL) or a
reserved sqlparser-rs (SQL) — both retired (ADR-0024 §migration Phase F);
the DSL and advanced-mode SQL are both parsed by the unified grammar
walker (ADRs 0024 / 0030–0036). Corrects the stack note, drops the
now-done "SQL handling in advanced mode" deferred bullet, and updates the
parser.rs layout comment.

Lower-confidence items (C1 rename, A1, I1a, I3, I4, T3, V2, export/import,
resume) left for a dedicated per-item reconciliation pass (handoff-45 §5).

claude@clouddev1 42306d33e3 fix: X4 — advanced-mode SQL INSERT auto-fills omitted non-PK serial (MAX+1)
A Form-A advanced-mode INSERT that omitted a non-PK serial column left it
silently NULL (the column is INTEGER UNIQUE, not NOT NULL, so SQLite
permits it), while simple-mode do_insert auto-fills it with MAX+1. That
violated ADR-0018 §1's "auto-generated on every path" contract and was the
unprincipled serial-vs-shortid asymmetry the ADR set out to remove
(advanced mode already auto-fills shortid).

Fix (decision: advanced mode matches simple mode): the advanced-mode
auto-fill reconstruction — renamed plan_shortid_autofill →
plan_autogen_autofill — now also fills an omitted non-PK serial with
MAX(col)+1 … MAX+n per row (single- and multi-row), reading MAX once under
the worker's single-writer serialisation. PK serial stays on the rowid
alias; Form B (no column list) still supplies every column. Honours
ADR-0018 §1/§5; no ADR amendment needed (the contract already said "every
path"). requirements.md X4 marked resolved.

claude@clouddev1 22e5bf5d6a feat: ADR-0035 4i(a,b) — CREATE TABLE help/usage + describe table constraints; Phase 4 complete
(b) describe shows table-level constraints: TableDescription gains
unique_constraints + check_constraints (populated by do_describe_table
from read_schema), rendered in a new "Table constraints:" section —
composite UNIQUE and table-level CHECK (named + unnamed). The per-column
Constraints column already covered single-column NOT NULL/UNIQUE/PK/CHECK.

(a) CREATE TABLE help/usage skeleton refreshed for the column DEFAULT/
CHECK/REFERENCES, table-level composite UNIQUE, table CHECK, and
table-level FOREIGN KEY forms (4a.2/4a.3/4b) — engine-neutral,
vocab-audit clean.

claude@clouddev1 f7e77a86f8 feat: ADR-0035 4h — ALTER TABLE … RENAME TO
The one genuinely new low-level op in Phase 4: a native engine RENAME TO
plus one-transaction reconciliation (commit-db-last) of everything the
engine does not track —

- every metadata row naming the table: __rdbms_playground_columns, both
  ends of __rdbms_playground_relationships (FK parent, child, and
  self-referential), and __rdbms_playground_table_checks;
- the CSV file, via the existing persistence rewrite+delete path
  (rewritten_tables=[new], deleted_tables=[old]) — no new method;
- CHECK text that qualifies a column with the old table name
  (T.age → U.age, column- and table-level): the engine rewrites the live
  CHECK but the stored text would drift and break a fresh rebuild (a
  planning-/runda finding); rewrite_check_table_qualifier keeps them in
  step. Bounded — a CHECK references only its own table.

Grammar: a fifth AlterTableAction (RenameTable { new }), added by
splitting the `rename` verb into one branch with an inner Choice on a
distinct second keyword (column vs to); the new-name slot mirrors the
CREATE TABLE name slot (NewName + reject_internal_table validator).

Refusals are engine-neutral and case-insensitive (the engine matches
names that way): same-name, case-only, existing-target, __rdbms_*, and
non-existent source. Auto-named indexes and relationships keep their
stale names (only table-name columns update — §6 scope). One undo step;
advanced-mode only; closes the rename half of C1.

Tests: 8 Tier-3 e2e + rewrite-helper unit tests + parse-dispatch tests.
Full suite 1903 passing / 0 failing / 1 ignored; clippy clean.

claude@clouddev1 6ff97f6e20 feat: ADR-0035 4g — ALTER TABLE add/drop constraint + add FK
ALTER TABLE <T> ADD [CONSTRAINT <name>] (CHECK | UNIQUE | FOREIGN KEY)
and DROP CONSTRAINT <name>. ADD = table-CHECK + composite UNIQUE + FK
(ADD PRIMARY KEY and a named UNIQUE refused — composite UNIQUE is
anonymous in our model). Each ADD reuses a low-level path with a dry-run
guard (table-CHECK/UNIQUE rebuild; FK -> add_relationship, bare
REFERENCES -> parent single PK). DROP CONSTRAINT resolves the name to a
named table-CHECK then a child-side FK, else refuses. One undo step each.

Named table-CHECKs round-trip: a nullable `name` column on
__rdbms_playground_table_checks (rebuild-only arrival; a named add on a
pre-4g project is refused with a "rebuild first" hint) plus a project.yaml
check_constraints {expr, name} extension (bare-string form still reads).
The internal-__rdbms_* guard was folded into do_add_constraint /
do_add_relationship, completing that guard class.

Grammar: the action Choice keeps one branch per verb (add/drop/rename/
alter) with an inner Choice fanning out on the distinct second keyword,
since the walker's Choice does not backtrack between same-led branches.

Tests: 7 Tier-1 parse + 2 yaml round-trip + 1 internal-guard + 9 Tier-3
e2e. Help/usage refreshed; ADR-0035 §13 4g + README + requirements.md in
lockstep.

claude@clouddev1 5b76315d1e feat: ADR-0035 4f — ALTER TABLE … ALTER COLUMN TYPE
Fourth AlterTableAction (AlterColumnType), runtime-decomposed to the
existing change_column_type executor with ForceConversion — which IS the
§7 advanced policy: lossy converts with a note (no force flag),
incompatible + the ADR-0017 static refusals (↔blob, same-type,
date↔datetime, non-int→serial) still refuse, while int→serial is allowed
(auto-fills nulls + UNIQUE, ADR-0018 §8). No new mode/note/persistence;
undo is the advanced safety net.

Grammar adds a fourth action branch leading on `alter`, discriminated in
the builder by the `type` keyword (unique — ADD COLUMN's type is an
ident); the type slot reuses SQL_TYPE. The internal-__rdbms_* guard was
folded into do_change_column_type (user-confirmed), closing the simple
`change column` exposure.

Tests: 7 Tier-3 e2e via run_replay + 4 Tier-1 parse (incl. a column-named-
`type` discriminator probe) + the simple-surface guard. Help/usage
refreshed; ADR-0035 §13 4f + README + requirements.md in lockstep.

claude@clouddev1 bbc2e34b33 feat: ADR-0035 4e — ALTER TABLE add/drop/rename column
Advanced-only `alter` entry word; ALTER TABLE <T> ADD COLUMN <col> <type>
[constraints] | DROP COLUMN <col> | RENAME COLUMN <old> TO <new> ->
SqlAlterTable, runtime-decomposed to the existing column executors
(do_add_column / do_drop_column / do_rename_column) — one undo step each,
no new worker layer. The COLUMN keyword is required (reserves bare
RENAME TO for 4h, ADD CONSTRAINT for 4g).

- ADD COLUMN takes NOT NULL / UNIQUE / DEFAULT / CHECK (no PK / inline
  REFERENCES). do_add_column extended to consume the SQL raw-text
  default_sql / check_sql (sql_expr is validate-only, the 4a.2
  mechanism), reaching parity with CREATE TABLE's column constraints.
- Drop/rename column refuse a column any CHECK references — table-level
  AND column-level (incl. a column's own self-check on rename) — the
  4a.3 deferral, detected up-front by tokenizing the raw CHECK text
  (skipping string literals). In the shared executors, so it guards both
  the simple and SQL surfaces and fixes a latent rename-drift bug that
  desynced the stored CHECK text and broke rebuild.
- SQL DROP COLUMN refuses an index-covered column (no --cascade SQL
  spelling — matches SQLite + the simple default).
- The column executors and do_add_index gained an internal-__rdbms_*
  guard (refuse as "no such table"), closing a pre-existing exposure on
  both surfaces. (do_change_column_type / do_add_constraint /
  do_add_relationship are a tracked follow-up.)
- `alter` is advanced-only; AlterTableAction::AddColumn is boxed
  (clippy::large_enum_variant).

Advanced-mode SQL CREATE [UNIQUE] INDEX [IF NOT EXISTS] [<name>] ON
<T> (cols) -> SqlCreateIndex and DROP INDEX [IF EXISTS] <name> ->
SqlDropIndex, both reusing the ADR-0025 executors (do_add_index /
do_drop_index), like 4c reused do_drop_table.

- CREATE UNIQUE INDEX admitted in advanced mode (ADR-0025 Amendment 1):
  ADR-0025 deferred UNIQUE indexes for the simple-mode DSL, but advanced
  mode trusts the user like SQL does. Adds an additive IndexSchema.unique
  flag (project.yaml, serde-default, version stays 1); rebuild re-emits
  CREATE UNIQUE INDEX; the redundant-set guard keys on (columns, unique).
  Simple-mode `add unique index` stays deferred.
- IF [NOT] EXISTS on both forms reuses the 4c no-op-with-note skip
  (journalled, not snapshotted) via CreateIndexOutcome / DropIndexOutcome.
- Unnamed CREATE INDEX auto-named (ADR-0025 convention); the [UNIQUE]
  prefix is a concrete-keyword Choice and the optional name an on-led-first
  selector (the drop-index selector precedent) — trap-safe.
- create/drop each gain a second advanced node; the existing all-candidates
  dispatch handles it (locked by parse tests).
- Unique indexes marked [unique] in the structure view and items panel.
- do_add_index refuses internal __rdbms_* tables as "no such table",
  closing a latent exposure on both the simple `add index` and the new
  SQL CREATE INDEX surfaces (ADR-0025 Amendment 1).

claude@clouddev1 e52e90c45b feat: ADR-0035 4c — DROP TABLE [IF EXISTS]
Add advanced-mode SQL `DROP TABLE [IF EXISTS] <name>` -> SqlDropTable,
executing through the existing do_drop_table (cascade / inbound-
relationship refusal / metadata cleanup) — full parity with the simple
`drop table`. The only new behaviour is `IF EXISTS` as a
no-op-with-note: a new DropOutcome::Skipped mirroring
CreateOutcome::Skipped (journalled, no snapshot), rendered via a new
ddl.drop_skipped_absent note + DslDropSkipped event.

- Grammar: SQL_DROP_TABLE node (entry `drop`, shape `table [if exists]
  <name> [;]`), registered Advanced. SQL-first dispatch: `drop table T`
  -> SqlDropTable in advanced; `drop column`/`relationship`/`index`/
  `constraint` fall back to the simple `drop` node (and still execute).
- Worker: Request::SqlDropTable + db.sql_drop_table; the if-exists-and-
  absent arm journals + replies Skipped without a snapshot, else
  snapshot_then(do_drop_table) -> Dropped.
- Completion: advanced `drop ` now surfaces the SQL `table` (the
  shared-entry-word behaviour from `create`); test split into simple
  (full DSL list) + advanced (SQL surface).

Known shared-entry-word completion unevenness (advanced `drop ` offers
only `table`; partial `drop rel` returns an empty list) deferred to 4i
(merge candidate sets for shared entry words) along with a flagged user
request to visually distinguish simple- vs advanced-mode completions in
the hint UI — tracked in ADR §13 4i (d)/(e), the 4c plan, and the
completion test. The DSL drops still parse + execute via fallback.

claude@clouddev1 76d60591bf feat: ADR-0035 4b — foreign keys in CREATE TABLE
Add foreign keys to advanced-mode SQL CREATE TABLE — the SQL spelling of
an ADR-0013 named relationship, created in the same transaction as the
table (one undo step).

- Grammar: inline `<col> … REFERENCES <parent>[(<col>)] [ON DELETE/UPDATE
  …]` (a new column constraint) and table-level `[CONSTRAINT <name>]
  FOREIGN KEY (<col>) REFERENCES …` (two new element branches — both
  start on a concrete keyword, never a leading Optional, which would
  abort the element Choice). Referential clauses reuse
  shared::REFERENTIAL_CLAUSES.
- Builder: greedy FK-clause consumption (parens consumed internally so
  they don't perturb the 4a.3 element-boundary depth tracker); inline FK
  auto-named, table FK takes an optional CONSTRAINT name.
- Worker: do_create_table resolves + validates each FK before building
  the DDL (self-ref validates against the in-statement columns/PK; bare
  REFERENCES resolves to the parent's single-column PK, composite ->
  error; PK-target + Type::fk_target_type compatibility), emits the
  FOREIGN KEY clause identically to schema_to_ddl, and writes the
  relationship metadata in the create transaction.
- Reuse: name/uniqueness/metadata-insert/type-compat factored into shared
  helpers; do_add_relationship refactored to use them.
- FKs round-trip via the existing relationship plumbing (no new
  persistence structures); describe surfaces the relationship.

Self-references and bare `REFERENCES <parent>` supported (user-confirmed).
Self-ref pre-submit indicator wrinkle deferred to 4i (tracked in ADR §13,
a code comment, and the plan).

DA/runda round added cross-cutting probes (FK survives the add-column
rebuild + a later rebuild_from_text; referential actions survive rebuild;
drop-child clears the relationship; drop-parent refused; bare self-ref
resolves to own PK) — all green, no fixes needed.

claude@clouddev1 60111f69d5 feat: ADR-0035 4a.3 — table-level / multi-column CHECK
Add table-level CHECK (e.g. `CREATE TABLE t (a int, b int, CHECK (a < b))`)
to advanced-mode SQL CREATE TABLE. Since SQLite exposes no PRAGMA for CHECK
constraints, a table-level CHECK cannot be read back from the engine and
becomes the source of truth in a new internal metadata table
`__rdbms_playground_table_checks (table_name, seq, check_expr)`.

- Grammar: new TABLE_CHECK element in ELEMENT_CHOICES.
- Builder: distinguishes a table-level CHECK from a column-level one by
  element position (no column-def open in the element), using depth-aware
  boundary tracking so a length-arg comma (`numeric(10,2)`) or a
  table-PRIMARY KEY's inner comma is not mistaken for an element separator.
- Worker: do_create_table emits the CHECK clauses and writes the metadata
  rows in its transaction; schema_to_ddl emits them identically on rebuild;
  read_schema / read_schema_snapshot read them from the metadata table;
  do_drop_table clears them.
- Persistence: TableSchema.check_constraints round-trips through project.yaml
  (#[serde(default)], optional on read), mirroring unique_constraints.
- Composite UNIQUE deliberately stays PRAGMA-detected (engine-reportable,
  unlike CHECK) — user-confirmed.

DA/runda round added cross-cutting tests and a forward-looking doc fix:
- table CHECK survives a rebuild triggered by `add column`, and a later
  rebuild_from_text (the ADR-0013 rebuild primitive uses a raw DROP, so the
  metadata rows keyed on the final name are preserved);
- dropping a column a table CHECK references fails cleanly (rollback, table
  intact); detection is 4e, friendly wording is H1;
- dropping a table clears its CHECK metadata (no orphan rows on re-create);
- amended ADR §6 so 4h's RENAME also updates the new metadata table.

claude@clouddev1 c0f5626787 feat: ADR-0035 4a.2 — per-column CHECK/DEFAULT + composite UNIQUE
Advanced-mode SQL CREATE TABLE gains the constraints that need no new
internal table (the 4a.2 slice):

- Grammar (sql_create_table.rs): column-level DEFAULT/CHECK and
  table-level UNIQUE(cols). DEFAULT is a literal or a *parenthesised*
  expression (standard SQL) — a bare sql_expr greedily eats a following
  NOT (NOT IN/LIKE/BETWEEN), breaking `DEFAULT 0 NOT NULL`; the parens
  bound it. CHECK is paren-bounded already.
- Builder (ddl.rs): captures CHECK/DEFAULT raw SQL text by byte span
  (sql_expr builds no AST) via capture_parenthesised_span /
  capture_expr_span; routes single-column table UNIQUE into the
  column's flag and composite UNIQUE into unique_constraints.
- Command/worker: ColumnSpec gains check_sql/default_sql (raw, preferred
  over the typed Expr/Value); Command::SqlCreateTable + Request +
  do_create_table gain unique_constraints; do_create_table emits raw
  CHECK/DEFAULT and composite UNIQUE clauses.
- Round-trip (part D): ReadSchema/TableSchema gain unique_constraints;
  read_schema detects composite UNIQUE via PRAGMA index_list origin 'u'
  (single-column still folds to the column flag); schema_to_ddl emits
  them; YAML RawTable/write_table round-trips (optional-on-read).
  CHECK round-trips via __rdbms_playground_columns.check_expr, DEFAULT
  via PRAGMA table_info — no new metadata table.

Table-level/multi-column CHECK remains 4a.3 (rejected "not yet
supported"); FK is 4b.

Tests: +7 builder (raw-text capture incl. the DEFAULT 0 NOT NULL
boundary the fix was found by; single/composite UNIQUE routing) and +4
Tier-3 (CHECK enforced, DEFAULT applied, composite UNIQUE enforced, and
all three survive a rebuild — the part-D round-trip). 1752 pass / 0 fail
/ 1 ignored; clippy clean. Plan + requirements.md updated.

claude@clouddev1 631074ff9c feat: ADR-0035 4a — SQL CREATE TABLE command, worker, and exit gate
Command + builder + worker for advanced-mode SQL CREATE TABLE
(sub-phase 4a), executed structurally through do_create_table:

- Command::SqlCreateTable + build_sql_create_table (ddl.rs): aliases via
  from_sql_name (incl. double precision), column- and table-level
  PRIMARY KEY, redundant-flag de-dup off a sole PK, IF NOT EXISTS.
  Advanced REGISTRY entry on the shared `create` word (SQL-first, DSL
  fallback); no-PK tables allowed (user-confirmed).
- Worker (db.rs): Request::SqlCreateTable + CreateOutcome + snapshot_then
  (one undo step); IF NOT EXISTS no-op (no snapshot, but journalled, like
  read-only commands). do_create_table inline-PK rule aligned with the
  rebuild generator schema_to_ddl — no round-trip DDL drift; serial
  autoincrement is independent of inline-PK (verified by round-trip
  tests).
- Runtime/App: dispatch + CommandOutcome::SchemaSkipped +
  AppEvent::DslCreateSkipped (structure + "already exists — skipped"
  note). Friendly catalog keys added (engine-neutral).

DEFAULT/CHECK/table-level UNIQUE are absent from the 4a grammar (parse
error with usage skeleton; friendly message + support land in the 4a.2
constraint slice) — user-confirmed.

Tests: type resolver, grammar shape, builder (incl. the PK
detection bug they caught), and tests/sql_create_table.rs (worker
round-trip, serial autoincrement first/non-first across rebuild, IF NOT
EXISTS no-op + journalling, no-PK table, one undo step) + a replay-as-
write test. 1739 pass / 0 fail / 1 ignored; clippy clean.

Exit gate: ADR-0035 Proposed -> Accepted (validated end-to-end by 4a);
README + requirements.md Q1 updated.
