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.

Initial planning docs: CLAUDE.md and ADRs 0000-0008
...
Captures up-front design decisions for RDBMS Playground:
stack (Rust + Ratatui + SQLite), input modes, project file
format, type vocabulary, undo snapshots and replay log,
sharing/export, and testing approach. ADR-0000 establishes
the ADR practice itself and mandates index upkeep alongside
any ADR change.
