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

ui: validity indicator rendering + warning theme colour (ADR-0027 step D)
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. |

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.

Indexes: add index / drop index, persistence, display (ADR-0025)
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-0019 §6: runtime enrichment + row pinpointing
Closes the placeholder-substitution gap reported during manual
testing: FK violations were rendering `<value>` and `<column>`
literally because the App had no schema awareness. With this
change the runtime resolves the schema-dependent facts before
the App ever sees the failure.
## Architecture
- **Database** gains two public methods backed by new worker
Request variants:
- `read_relationships(table)` → (outbound, inbound) FK list
(lifts the previously-private `read_relationships_*` pair
into the public surface, behind a `RelationshipsReply`
type alias).
- `find_rows_matching(table, column, value, limit)` →
`DataResult` for row pinpoint queries.
- **friendly module** gets:
- New `FailureContext` struct: schema-resolved facts the
runtime builds (table, column, value, parent_table,
parent_column, child_table, optional diagnostic_table).
- `TranslateContext` loses its lifetime parameter and gains
`parent_table` / `parent_column` fields. All string fields
are now `Option<String>` for ownership simplicity.
- `TranslateContext::from_facts(operation, verbosity, facts)`
helper.
- Translator's FK paths now use `ctx.parent_table` /
`ctx.parent_column` for child-side wording; FK Update gets
a dedicated `fk_child_side_update` arm.
- FK dispatch is enrichment-driven first
(`parent_table` set → child-side; `child_table` set →
parent-side), with operation as the tiebreaker.
- The translator forwards `ctx.diagnostic_table` onto the
`FriendlyError` so pinpointed rows render through the
existing ADR-0017 §7 bordered renderer.
- **Event** `DslFailed` carries `(command, error, facts)`.
The runtime populates `facts` via `enrich_dsl_failure`
before posting the event.
- **Runtime** `enrich_dsl_failure(database, command, error)`
classifies and resolves:
- UNIQUE INSERT/UPDATE: parses `T.col` from engine message,
finds the user's attempted value (with schema fallback
for natural-order multi-value INSERT — including the
serial/shortid auto-skip rule from `do_insert`), pinpoints
the existing conflicting row(s) via `find_rows_matching`
and renders as a `DiagnosticTable`.
- NOT NULL INSERT/UPDATE: parses `T.col`; no value
(definitionally null) and no pinpoint (engine doesn't
identify the row).
- FK INSERT/UPDATE: outbound relationship lookup picks the
FK column the user is touching; resolves
`parent_table`/`parent_column`/`value`. UPDATE falls back
to inbound (parent-side) when no outbound match.
- FK DELETE: inbound relationship lookup picks a child_table
that references this row.
- **App** drops its old `attempted_value_for` /
`column_from_qualified_target` helpers (their work moved to
runtime where the Database is in scope).
`build_translate_context` combines the runtime-supplied
facts with the operation derived from the Command and the
App's verbosity.
## Manual-test fixes folded in
Two issues surfaced during manual testing of the initial
implementation, both fixed:
1. Natural-order multi-value INSERT
(`insert into Orders values (4, 11.99)`) skipped FK
enrichment because `user_value_for_column` only knew the
single-value short form. The schema-aware lookup
(`user_value_for_column_with_schema`) now mirrors
`do_insert`'s position-mapping rule (auto-generated
columns skipped), so positional INSERTs onto tables with
serial/shortid PKs resolve correctly. Regression test:
`enrich_fk_insert_natural_order_multi_value_resolves_via_schema`.
2. The arity error on INSERT now lists the columns it
expected — `expected 3 value(s) for (id, Name, Email), got 2`
instead of the bare count. Surfaces what the user needs
to fix without making them go check the schema.
## Tests
`tests/friendly_enrichment.rs` (+8 integration tests):
- UNIQUE INSERT with explicit columns: facts.{table, column,
value, diagnostic_table} all resolved; pinpoint shows
conflicting row.
- UNIQUE INSERT natural-order short form: schema fallback
resolves the value.
- UNIQUE UPDATE: value pulled from assignments.
- NOT NULL INSERT: table+column resolved, value None
(correct), no pinpoint.
- FK INSERT: parent_table, parent_column, value all resolved
via outbound relationship lookup.
- FK INSERT natural-order multi-value: schema-aware lookup
with auto-skip resolves correctly (regression for the
manual-test bug).
- FK DELETE: child_table resolved via inbound relationship
lookup.
- DbError::Unsupported: enrichment returns default
FailureContext (no false positives).
App-level tests updated to populate `FailureContext` directly
(simulating runtime enrichment) for the verbosity / threading
checks.
## Tally
610 tests passing (was 603: +8 enrichment integration tests
minus 1 obsolete App-side helper test that the runtime
absorbed). Clippy clean with nursery lints. Release builds.

ADR-0019 implementation: friendly error layer + i18n catalog
All eight implementation steps from ADR-0019's §"Order of
operations":
Step 1 — `src/friendly/` module skeleton; `t!()` macro; YAML
catalog loader (`include_str!` + `serde_yml`); `{name}`
substitution helper that rejects format specifiers per §8.4.
Step 2 — `error.*` catalog populated for UNIQUE / FK /
NOT NULL / CHECK / type-mismatch / not_found / already_exists /
generic / invalid_value, with verbose hints per
pedagogical-voice rule (§5). Anchor phrases (§10) preserved
verbatim.
Step 3 — `FriendlyError { headline, hint, diagnostic_table }`
+ renderer composing the three blocks per §7.
Step 4 — `translate(&DbError, &TranslateContext) → FriendlyError`.
Classifies by `SqliteErrorKind` first, then by message text
for the constraint family. `change column` failures route to
the type-mismatch headline, subsuming the previous
`friendly_change_column_engine_error` helper.
Step 5 — `DbError::friendly_message()` delegates to the
translator with default context. Removed
`friendly_change_column_engine_error` (absorbed) and
`enrich_fk_message` (FK list moves to the deferred re-query
step). One test rewritten to assert on the engine-classified
payload rather than the removed enrichment text.
Step 6 — `messages (short|verbose)` app-level command parallel
to `mode`. `App::messages_verbosity` (default verbose)
threaded into `TranslateContext` via
`App::build_translate_context`. `AppEvent::DslFailed` now
carries the structured `DbError`, plus the App extracts the
user's attempted value from `Command::Insert` / `Update`
to fill the `{value}` placeholder for UNIQUE / NOT NULL.
Step 7 — Catalog validator (§8.6) checks for missing keys,
unused/undeclared placeholders, format specifiers, and
forbidden engine vocabulary. `main.rs` parses the embedded
catalog at startup so a corrupted build artefact fails
loudly there rather than at the first `t!()` call.
Step 8 — Anchor phrases (§10) held: existing tests asserting
on "no such table", "already exists", "cannot be converted",
etc. all pass without rewording.
## Tally
603 tests passing (was 561: +42 net). Clippy clean with
nursery lints. Release binary 7.7 MB.
## Deliberately deferred
- Schema-aware enrichment for FK violations (parent_table /
parent_column / child_table) and the multi-value
natural-order INSERT case for UNIQUE. Both need the
Database handle in scope at translation time, so they
bundle naturally with the row-pinpoint re-query work
(ADR-0019 §6) — that follow-on adds runtime-side
enrichment via a `Database` lookup and a structured
failure-context carried on `DslFailed`. Until then,
unfilled placeholders render as their `{name}` form for
visual consistency with the catalog.
- Migration sweep (§9). Only `error.*` is catalog-driven so
far; `help.*`, `ok.*`, `client_side.*`, `replay.*`,
`parse.*`, modal labels, etc. migrate per-PR.
- Settings persistence for `messages`. In-session state for
now; waits on the future settings ADR.

ADR-0016 + Iter 5/6 follow-up: pretty table rendering
Replaces the placeholder pipe-and-dash output with Unicode box-drawing tables for both data results and table-structure listings, per ADR-0016. * New `src/output_render.rs` module with `render_data_table` and `render_structure`. Hand-rolled to match the project's existing CSV/YAML pattern; ~300 lines. * Header-only outer-frame border style: outer ┌─┐│└─┘ box + ├─┤ header underline, no per-row separators. NULL renders as `(null)`; cell newlines/tabs/control chars become `↵`/`→`/`·` as display-only substitutions. * Type-aware column alignment: numeric types right-aligned, everything else left. `DataResult` gains a `column_types: Vec<Option<Type>>` field, populated from the existing metadata lookup at the two query sites in db.rs (no new query paths). * Structure view shows Name | Type | Constraints columns; References / Referenced-by sections retain plain-text format, leaving room for the future relationship-rendering ADR. * 18 new unit tests in output_render.rs (plus 4 insta snapshots for the canonical layouts). Existing assertions in app.rs and walking_skeleton.rs updated to match the new format. Total: 426 passing, 0 failing, 0 skipped (up from 408). Clippy clean. |

Iteration 2: per-command write-through to project.yaml, CSVs, history.log
Every successful user command now persists through to YAML, the
affected CSVs, and history.log inside the same SQLite transaction,
with the commit-db-last ordering from ADR-0015 §6: validate ->
mutate -> stage text + fsync -> atomic rename -> append history ->
commit. A failure in any text-write step rolls back the SQLite tx,
so disk state is unchanged on failure. Persistence failures are
routed through a new AppEvent::PersistenceFatal which sets a
fatal_message on the App, emits Action::Quit, and is printed to
stderr after terminal teardown so the banner remains above the
shell prompt (ADR-0015 §8).
New persistence module owns the file formats: hand-rolled YAML
schema writer, per-type CSV encoder (RFC 4180, NULL distinct from
empty string, base64 blobs), append-only history.log with ISO-8601
timestamps and successful-only entries. Atomic per-file writes via
tmp + fsync + rename.
The db worker holds an Option<Persistence>; tests still use
Database::open(":memory:") with no persistence. Action::ExecuteDsl
gains a source field carrying the user-typed text, threaded
through to history.log.
Tests: 289 passing (256 lib + 7 new integration + 9 lifecycle + 17
walking-skeleton), 0 failing, 0 skipped. Clippy clean with nursery
lints.

INSERT/UPDATE/DELETE + value model + auto-show, with polish
DSL data operations (ADR-0014): - insert into T [(cols)] values (vals); short form insert into T (vals) omits values keyword for friendlier syntax. - update T set ... where col=val | --all-rows; delete from T where col=val | --all-rows; show data T. - Value AST (Number/Text/Bool/Null) with per-column-type validation in the executor: int/real/decimal/bool/date/ datetime/shortid each accept a documented literal shape and produce friendly format errors naming the column. - INSERT short form fills non-auto-generated columns in schema order; auto-fills serial via SQLite and shortid via the new generator (T2). - `add column [to table] T: c (type)` -- `to table` now optional. Database: - insert/update/delete via prepared statements with bound rusqlite::types::Value parameters. - InsertResult/UpdateResult/DeleteResult: writes return rows_affected plus the affected row(s) only (not the whole table), so users see exactly what changed. - INSERT shows the just-inserted row via last_insert_rowid. - UPDATE captures matching rowids up-front and fetches them post-update -- works even if the UPDATE changed the WHERE column. - DELETE reports per-relationship cascade effects by row- count diffing inbound child tables; UPDATE-side cascades are not yet detected (would need value diffing). - query_data formats cells (booleans true/false, NULLs as None). FK error enrichment: - Now lists both outbound (INSERT/UPDATE relevance) and inbound (DELETE/UPDATE on parent relevance) FKs from the metadata, so RESTRICT errors point at the children blocking the delete. - RelationshipSelector has a proper Display impl -- "no such relationship" reads cleanly. Relationship display: - target_table for AddRelationship/DropRelationship now returns the parent (1-side); structure rendering after add/drop shows that side's "Referenced by:" entry, matching the `from <Parent>` direction of the command. - [ok] summary uses display_subject so relationship commands show both endpoints (`from P.col to C.col`) rather than a single misleading table name. - Auto-name format `<Parent>_<pcol>_to_<Child>_<ccol>` (matches the from..to direction). Output rendering and scrolling: - Wrap-aware scroll: renderer reports both visible-row count and total wrapped-row count to App; scroll math caps against actual displayable rows. Long lines wrap; the bottom line is always reachable; PageUp/PageDown work correctly even after paging past the buffer top. - Multi-line messages (FK error enrichment, cascade summary) split into single-line OutputLines at creation time so wrap/scroll math agree. Runtime / events: - New AppEvent variants for Insert/Update/Delete success carrying typed result structs; DslDataSucceeded reserved for show-data queries. Docs: - ADR-0014 covers data-op grammar, value model, --all-rows safety, auto-show. - requirements.md: C5 done, T2 done, V2 partial (basic data view), V5 partial (show data added). New entries: C5a complex WHERE expressions; H1 progress note for FK enrichment; H1a (strong syntax-help in parse errors). Tests: 200 passing (183 lib + 17 integration), 0 skipped. Includes parser, type-validation, DB write/read, FK-failure enrichment, cascade-delete propagation, focused-auto-show behaviour, scroll-cap invariants. Clippy clean with nursery enabled. |

Foreign-key relationships, rebuild-table, polish round
DSL:
- add 1:n relationship [as <name>] from <P>.<col> to <C>.<col>
[on delete <action>] [on update <action>] [--create-fk]
- drop relationship <name> | from <P>.<col> to <C>.<col>
- show table <name> for re-displaying a structure on demand
Database (ADR-0013):
- Rebuild-table primitive following SQLite's
ALTER-via-rebuild recipe (foreign_keys=OFF outside tx,
copy-by-name, foreign_key_check before commit). Reusable for
B2 (column drops/renames/type changes).
- ReferentialAction enum (no action / restrict / set null /
cascade); SET DEFAULT awaits column DEFAULTs.
- __rdbms_playground_relationships metadata table -- names,
auto-generated as <Parent>_<pcol>_to_<Child>_<ccol>.
- Type::fk_target_type() validation at declaration; friendly
errors for type mismatch, non-PK target, missing column,
duplicate name.
- describe_table populates symmetric outbound + inbound
relationship lists. drop_table refuses while inbound
references exist; outbound metadata cleaned up alongside drop.
App / UI:
- In-line cursor editing in the input field: Left, Right,
Home, End, Delete, Backspace honoring UTF-8 boundaries.
- PageUp / PageDown scrolls the output buffer; viewport row
count fed back from the renderer via App::note_output_viewport
so scroll is capped against the actual visible area
(regression-tested) and snaps to the bottom on new output.
- Failure messages quote the command portion ("verb target"
failed: ...) for visual clarity; RelationshipSelector has a
proper Display impl so "no such relationship" reads cleanly.
- Structure rendering shows References / Referenced by sections.
Docs:
- ADR-0013 covers naming, metadata table, symmetric view, and
the rebuild-table strategy.
- requirements.md updates: C3 (FK done), B2 (primitive in),
T3 (compound-PK FK still pending). New entries: I1a (cursor
editing -- landed), I1b (Ctrl-A/E and readline shortcuts --
pending), V4 partial scroll, V5 (show family), C3a (modify
relationship -- deferred).
Tests: 154 passing (140 lib + 14 integration), 0 skipped.
Clippy clean with nursery enabled.

DSL parser, async DB worker, types, history, metadata, polish
Track 1 implementation plus polish round. Parser (chumsky): - Grammar-based DSL producing a typed Command AST. - create table X with pk [name:type[,name:type...]] supports arbitrary names, any user type, compound PKs natively. Bare form errors with a friendly hint pointing at `with pk`. - add column to table X: Name (type); drop table X. - Required clauses use keyword grammar; -- reserved for opt-in flags (ADR-0009). Custom Rich reasons preferred when surfacing chumsky errors so unknown-type messages list valid alternatives. Database (ADR-0010, ADR-0012): - rusqlite + STRICT tables + foreign_keys=ON. - Dedicated worker thread; mpsc Request inbox, oneshot replies. - Typed DbError with friendly_message() hook for H1. - Internal __rdbms_playground_columns metadata table preserves user-facing types across schema reads, atomically maintained alongside DDL via Connection transactions. list_tables hides it via the new __rdbms_ internal-table convention. Types (ADR-0005, ADR-0011): - All ten user-facing types: text, int, real, decimal, bool, date, datetime, blob, serial, shortid. - Type::fk_target_type() for FK-side column-type rule (Serial->Int, ShortId->Text, others identity) -- foundation for the FK iteration. App / Runtime / UI: - update() stays pure-sync; runtime dispatches DSL via spawned tasks, results post back as AppEvent::Dsl*. - Items panel renders live tables list; output panel shows the user-facing structure of the current table after each DDL. - In-memory command history (Up/Down, draft preservation, consecutive-duplicate dedup) -- I2 partial. - Mouse capture removed; terminal native text selection restored (toggle approach revisited when scroll/click features land). Docs: - ADRs 0009 (DSL syntax conventions), 0010 (DB worker), 0011 (FK type compat), 0012 (internal metadata table). - requirements.md progress notes; new V4 entry for the scrollable session-log + inline rich rendering + Markdown export direction. Tests: 103 passing (91 lib + 12 integration), 0 skipped. Clippy clean with nursery enabled. |

TUI walking skeleton (Phase 4)
First implementation milestone: Cargo project, dependencies,
and a minimal but functional TUI shell built on Ratatui +
Crossterm + Tokio in the Elm-style update/view pattern
(Candidate A from Phase 2/3 selection).
Includes:
- Three-region layout: items list (left), output + input + hint
(right), bottom status bar with mode-aware shortcuts.
- Two themes (light, dark) plus COLORFGBG auto-detect, per
NFR-7. CLI: --theme {light,dark}, --log-file <path>.
- Input modes per ADR-0003: simple (default), advanced, with
the `:` one-shot escape including immediate prompt reaction
("Advanced:" label, advanced border) and auto-inserted space
after a leading `:` in simple mode.
- App-level commands: `quit`/`q`, `mode simple`/`mode advanced`
(canonical list per ADR-0003 — remaining commands land in
later iterations).
- File logging via tracing, defaulting to ~/.rdbms-playground/
playground.log so the TUI is not corrupted by stdio.
Testing per ADR-0008:
- Tier 1: 29 unit tests covering input handling, mode switch,
one-shot escape, auto-space, output buffering, CLI parsing.
- Tier 2: 4 insta snapshots (default simple/advanced/light,
one-shot active) of TestBackend frames.
- Tier 3: 7 integration tests driving synthetic events through
App::update + render path.
All green: 36 tests, 0 failures, 0 skips. Clippy clean with
nursery lints enabled.
