ADR-0024 ranker hook scaffolding
Adds the `Ranker` plug-in point ADR-0024 §ranker-layer specified. The grammar tree declares *what's valid*; the ranker decides *what's likely useful first*. Default `identity_ranker` preserves declaration order from the grammar. API: - `pub type Ranker = fn(Vec<Candidate>) -> Vec<Candidate>;` - `pub const fn identity_ranker(c) -> Vec<Candidate>` returns its input unchanged. - `candidates_at_cursor_with(input, cursor, cache, ranker)` applies a custom ranker; the default `candidates_at_cursor` delegates with `identity_ranker`. Three new tests cover identity preservation, custom reordering, and the empty-list-collapses-to-None edge. This is a future-work hook — no production caller passes a non-identity ranker yet. Hooks for frequency-based ranking, content-aware priors, or recency plug in here without touching the grammar declarations. Tests: 809 passing, 0 failing, 1 ignored. Clippy clean. |

ADR-0024 Phase F (full) step 5: walker-driven completion
Replaces the `ParseError::Invalid::expected: Vec<String>`
round-trip with structured `Expectation`s direct from the walker
(ADR-0024 §architecture). The completion engine no longer parses
formatted strings back into types — `Expectation::Ident { source,
role }`, `Expectation::Word`, `Expectation::Literal`,
`Expectation::Flag`, `Expectation::NumberLit`, and
`Expectation::StringLit` are consumed as enum variants.
New helper:
- `walker::expected_at_input(source) -> Vec<Expectation>`
consolidates the empty-input case (returns every CommandNode
entry word), unknown-command-word case (also entry words), and
walker-engaged case (Incomplete / Mismatch expectations) in one
place. ValidationFailed and Match resolve to empty.
`completion.rs` refactor:
- `expected_at(leading)` wraps the walker helper; replaces the
legacy string-based `expected_set`.
- Keyword candidates: filter `Expectation::Word(w)` /
`Expectation::Literal(s)` to alphabetic-only literals (no
more string-parsing / `strip_backticks`).
- Type names: detect `Expectation::Ident { source:
IdentSource::Types }` directly (replaces the `TYPE_SLOT_LABEL`
magic string).
- Flag candidates: read `Expectation::Flag(body)` and format
as `--{body}` (replaces backticked-string matching).
- Composite-literal candidates: match against
`Expectation::Literal("1")` (replaces the backticked-string
`` `1` ``).
- Schema identifiers: `Expectation::Ident { source, .. }`
filtered by `source.completes_from_schema()`.
- `is_value_literal_signature` checks for `Expectation::Word`
values "null"/"true"/"false" and `Expectation::NumberLit` +
`Expectation::StringLit` variants (replaces backticked-string
matching).
- `invalid_ident_at_cursor` and `typing_name_at_cursor` adopt
the same path.
The `typing_name_at_cursor` probe (substitute placeholder and
re-parse) still goes through `parse_command` because the probe
specifically wants the *post-name* expected set — `parse_command`
+ the string `expected` field carries that today. A future
follow-up could thread the structured probe through `walker`,
but the value-add is marginal.
`COMPOSITE_CANDIDATES` opener key changes from `` `1` `` (the
backticked-string the chumsky parser produced) to bare `"1"`
(the Expectation::Literal payload).
Touched modules: `dsl/walker/mod.rs` (new export),
`src/completion.rs` (refactor).
Tests: 806 passing, 0 failing, 1 ignored — every existing
completion test passes unchanged, proving the structured path
is behaviour-preserving. Clippy clean.

ADR-0024 Phase F (full) step 4: catalog token-keyword cleanup
Drops the 47 `parse.token.keyword.*` and 6 `parse.token.punct.*`
catalog entries (and their `KEYS_AND_PLACEHOLDERS` declarations).
Nothing consumes them: the walker renders keyword wording in
`format!(\"`{word}`\")` directly, sourced from grammar-tree Word
literals; punct wording surfaces the same way via
`Expectation::Punct(ch)`.
Structural-class labels (`parse.token.identifier`,
`parse.token.number`, `parse.token.string_literal`,
`parse.token.flag`, `parse.token.end_of_input`) and the lex-error
wordings (`parse.token.error.{bad_flag,unknown_char,
unterminated_string}`) stay. These are not derivable from the
grammar tree and the walker's expected-set / validator paths still
read them.
`friendly::keys::tests::keys_validate_against_catalog` continues to
assert catalog ↔ `KEYS_AND_PLACEHOLDERS` bidirectional coverage,
so the trimmed declaration is pinned against the trimmed catalog.
Tests: 806 passing, 0 failing, 1 ignored. Clippy clean.

ADR-0024 Phase F (full) step 3: delete legacy parser modules
Removes the last consumers of `dsl::lexer`, `dsl::keyword`, and
`dsl::ident_slot`, then deletes the modules.
- `Theme::token_color(&TokenKind)` deleted along with its test;
`Theme::highlight_class_color(HighlightClass)` is the sole
highlight-colour mapper (the walker's `per_byte_class` feeds
it directly).
- `IdentSource` (`dsl::grammar`) absorbs the schema-list /
expected-label / round-trip semantics that previously lived
on `IdentSlot`. Adds `completes_from_schema`, `expected_label`,
and `from_expected_label` methods. The walker's
`Expectation::Ident { source }` and the schema-lookup request
on the database worker now share one enum.
- `SchemaCache::for_slot(IdentSlot)` → `for_source(IdentSource)`.
- `Database::list_names_for` and the `Request::ListNamesFor`
worker variant take `IdentSource`. Internal tables and column
/ relationship lookups dispatch on the same enum.
- `InvalidIdent.slot: IdentSlot` → `InvalidIdent.source: IdentSource`.
The `invalid_ident_at_cursor` rendering branch in
`input_render.rs::ambient_hint` updates accordingly.
- Completion's keyword filter (`Keyword::from_word`) becomes
"backticked items whose payload is all ASCII alphabetic" —
punct and digit literals still surface through their own
candidate sources (composite-literal, flag, schema-ident);
the alphabetic filter excludes them from the keyword bucket.
- `friendly::keys::tests::keyword_and_punct_have_complete_token_vocabulary`
is dropped. It cross-checked `Keyword::ALL` / `Punct::ALL`
against catalog entries; both enums are gone. The
`parse.token.keyword.*` / `parse.token.punct.*` catalog
entries themselves survive for one more commit (catalog
cleanup, ADR-0024 §cleanup-pass); the
`keys_validate_against_catalog` test still pins them.
- Modules deleted: `src/dsl/lexer.rs`, `src/dsl/keyword.rs`,
`src/dsl/ident_slot.rs`.
Tests: 806 passing, 0 failing, 1 ignored. The drop from 852
reflects the removed module-internal tests (~32 lexer, 7
keyword, 4 ident_slot, 1 theme token_color, 1 friendly keys
keyword/punct), and is the expected outcome.
Clippy clean with `nursery` lints + `-D warnings`.

ADR-0024 Phase F (full) step 2: usage via CommandNode.usage_ids
Migrates parse-error usage-block rendering from the legacy `dsl::usage::matched_entry` (which scanned a `Vec<Token>` for the first matched Keyword) to walker-side lookup driven by each `CommandNode`'s `usage_ids` slice. `CommandNode.usage_id: Option<&'static str>` becomes `usage_ids: &'static [&'static str]`. Multi-form families (`drop`, `add`, `show`) carry every variant — `drop` lists table/column/relationship templates; `add` lists column / relationship; `show` lists data / table. The single-shape commands carry their single catalog key. App-lifecycle CommandNodes had pointed at non-existent `parse.usage.app.*` keys (never noticed because the field was unused); they now point at the real catalog entries (`parse.usage.quit`, `parse.usage.help`, …). New helpers in `dsl::grammar`: - `usage_keys_for_input(source) -> Option<(entry_word, usage_ids)>` resolves the first identifier-shape token to a CommandNode and returns its usage_ids list. Used by `app::render_usage_block` and `input_render::ambient_hint`. - `entry_words_alphabetised() -> Vec<&'static str>` replaces `dsl::usage::entry_keywords_alphabetised`. `dsl::usage` is deleted. The "available commands:" fallback in `render_usage_block` now formats entry words as `` `<word>` `` directly (matching the `parse.token.keyword.*` catalog renders); the per-keyword catalog wrappers will collapse in the next step (ADR-0024 §cleanup-pass §F). `parse_command` and `parse_tokens` slim down: - `parse_command(input)` no longer pre-lexes — the walker scans source bytes directly. - `parse_tokens` (internal-only `pub` for "future I3/I4 work") is removed; its body folded into `parse_command`. - `unknown_command_error` reads the walker registry directly. Touched modules also drop their `crate::dsl::lexer::lex` and `crate::dsl::usage` imports: `app.rs`, `input_render.rs`, `completion.rs`. Tests: 852 passing, 0 failing, 1 ignored (down from 860 because the 8 `dsl::usage::tests::*` tests are gone with the module). |

ADR-0024 Phase F (full) step 1: walker-driven highlighting
Replaces the lex()-driven `base_runs` span builder in `input_render.rs` with `walker::highlight_runs`. The new walker-side `dsl::walker::highlight` module returns per-byte `HighlightClass` assignments for every token shape in the source: - For commands the walker engages on, `WalkResult::per_byte_class` is the authoritative source (keyword / identifier / number / string / punct / flag). - Trailing junk past a partial match — and inputs the walker doesn't engage on at all (no registered entry word) — fall through to a byte-shape scanner over `lex_helpers` so unknown command words, stray punctuation, and unterminated strings still highlight sensibly. `Theme::highlight_class_color` is the walker-side analogue of `token_color(&TokenKind)`; the renderer reads `walker::highlight_runs` output and looks up colours through it. `token_color` and the `lex()` pre-pass remain in place for now — the lexer module is still consumed by usage rendering and completion until the remaining Phase F steps land. `HighlightClass`'s and `WalkResult::per_byte_class`'s `#[allow(dead_code)]` annotations come off — they're now part of the production highlight path. Tests: - 16 new tests under `dsl::walker::highlight` cover end-to-end walks, byte-shape fallbacks (unknown commands, bare flags, numbers, punctuation), UTF-8 codepoint advance, and trailing- token handling after partial walks. - Existing `input_render` tests pass unchanged. - 860 total tests passing (727 lib + 133 integration), 1 ignored. Clippy clean with `nursery` lints + `-D warnings`. |

ADR-0024 Phase F (minimal): drop chumsky from the parse path
Delete the chumsky-side command_parser and its per-command sub-parsers, error humanisation helpers, and keyword/punct/ ident/value-literal combinators. The unified-grammar walker in `crate::dsl::walker` is now the sole parse path. parse_tokens flow (post-Phase F): 1. lex(input) — still produces the Token stream that completion / highlighting / echo-line consumers depend on. 2. try_walker_route(source) — walker handles every entry keyword in REGISTRY (20 commands across 14 entry words). 3. unknown_command_error(source) — synthetic ParseError for inputs whose first identifier-shape token isn't a registered entry word. Wording mirrors the chumsky-side "expected one of `add`, `change`, …, found `<word>`" structural error the legacy top-level Choice produced. Cargo.toml: chumsky dependency dropped (no remaining uses). Cargo.lock regenerated; ~58 lines net reduction in the dependency graph. Scope intentionally deferred (separate follow-up): - dsl/lexer.rs, dsl/keyword.rs, dsl/ident_slot.rs, dsl/usage.rs::REGISTRY: still consumed by completion.rs, input_render.rs, app.rs, theme.rs, db.rs, runtime.rs, friendly/keys.rs. Removing these requires migrating each consumer to the walker's per-byte-class output / grammar REGISTRY / IdentSource enum. Substantial blast radius; worth a dedicated session. - parse.token.keyword.* catalog entries (40+): used by usage.rs and parse-error rendering for the unmigrated consumers above. Collapse follows after the consumer migration. Tests: - All existing parser tests (`dsl::parser::tests`) ported in place; they call `parse_command` which now flows through the walker. 844 passed, 0 failed, 1 ignored — same count as Phase E (no test additions, no regressions). - cargo clippy --all-targets -- -D warnings clean. - cargo build (release-like dev profile) succeeds. |

ADR-0024 Phase E: replay end-to-end
Migrate `replay <path>` to the walker. Shape is Choice(StringLit, BarePath); the StringLit branch handles the quoted form (with the existing `''` escape), and BarePath handles the unquoted form. Per ADR-0024's path-bearing UX change (already shipped for import / export in Phase A), bare `replay` paths terminate at the first whitespace byte. Paths with spaces require the quoted form. The legacy `try_parse_replay_with_bare_path` source-slice helper in dsl/parser.rs is removed; the chumsky-side replay branch in command_parser stays declared but unreachable until Phase F sweeps the chumsky path. Tests: - 7 new walker-specific tests for replay: bare relative path, bare absolute path, quoted with whitespace, quoted with escaped quote, case-insensitive keyword, missing-path error, empty-quoted-path parses to empty (runtime layer rejects). - Total: 844 passed, 0 failed, 1 ignored (was 838 / 1). - cargo clippy --all-targets -- -D warnings clean. |

ADR-0024 Phase D: data commands at chumsky parity
Migrate the four data commands at four entry words: show
(show data / show table), insert, update, delete. Walker now
owns the entire command set introduced through ADR-0014.
Scope deviation from ADR-0024: full schema-aware value typing
via DynamicSubgrammar(column_value_list) is deferred. The
walker accepts any value at any position — matching the
existing chumsky parser's behaviour, where per-column type
checks happen at bind time. The DynamicSubgrammar Node
variant and WalkContext schema fields stay declared so the
infrastructure is in place when the schema cache plumbs
through parse_command (a future refinement). All existing
tests pass on the new shape.
Walker extensions:
- StringLit terminal — wired to the consume_string_literal
helper that mirrors the legacy lexer's `''` escape handling.
MatchedItem text carries the unescaped payload; span covers
the surrounding quotes.
- Bridge: Incomplete error wording now appends `, found end
of input` (matching the chumsky-side structural error
contract that `structural_error_for_show_data_without_arg`
asserts on).
Grammar:
- src/dsl/grammar/data.rs: SHOW (Choice of show_data /
show_table), INSERT (three forms folded into a single shape
via a Choice ordered to disambiguate Form B's `values`
keyword from Forms A/C's `(`-prefixed content; the inner
paren list is a Choice(VALUE_LITERAL, Ident{Columns}) with
VALUE_LITERAL ordered first so `true`/`false`/`null` match
their Word branch rather than the broader identifier catch-
all), UPDATE (assignments + filter), DELETE (filter).
- VALUE_LITERAL = Choice(Word("null"), Word("true"),
Word("false"), NumberLit, StringLit) — matches the chumsky
`value_literal()`.
- WHERE_CLAUSE / FILTER_CLAUSE shared between update and
delete.
- AST builders walk MatchedPath items in order, using role
tags (`update_set_column`, `filter_column`,
`insert_first_item`) to discriminate column references
belonging to different shapes within the same command.
Tests:
- 13 new walker-specific tests covering all data forms:
show data / show table, insert with each of three forms,
insert with negative numbers, update with single + multiple
assignments + where, update with --all-rows, delete with
where, delete with --all-rows, update/delete without filter
errors, replay still routes via chumsky.
- Total: 838 passed, 0 failed, 1 ignored (was 825 / 1).
- cargo clippy --all-targets -- -D warnings clean.

ADR-0024 Phase C: create table with column-list value literals
Migrate `create table <Name> [with pk [<col>:<type>[, ...]]]`
to the walker. Exercises Repeated{separator: Some(Punct(','))}
for the first time — the with-pk column-spec list.
Walker behaviour changes:
- Optional now backtracks on partial-match failure (Incomplete
or Failed-Mismatch from a Seq mid-shape). Path / per-byte
state rolls back to before the partial attempt; the inner's
expected-set propagates as `skipped` so callers see "what
would have completed it". Matches chumsky's `or_not`
semantics. ValidationFailed (content errors) does NOT
backtrack — the user means to fix those.
- Bridge: ValidationFailed errors now classify as
`at_eof = true`, mirroring the chumsky-side custom-error
convention. This is what lets `create table Customers`
classify as IncompleteAtEof rather than DefiniteErrorAt
(the user can still continue typing `with pk …`).
Grammar:
- src/dsl/grammar/ddl.rs gains CREATE: shape is
Seq(Word("table"), Ident{NewName,table_name}, Optional(WITH_PK))
where WITH_PK = Seq(Word("with"), Word("pk"),
Optional(Repeated{COL_SPEC, separator: Punct(','), min:1})).
AST builder enforces `with pk needs at least one column`
with the existing parse.custom.create_table_needs_pk catalog
wording; `with pk` alone defaults to id:serial.
Tests:
- 6 new walker-specific tests for create_table: with-pk
default, named typed PK, compound PK, whitespace tolerance
around `:` and `,`, bare-create-table-errors-with-with-pk-
hint, case-insensitive keywords.
- Total: 825 passed, 0 failed, 1 ignored (was 819 / 1).
- cargo clippy --all-targets -- -D warnings clean.

ADR-0024 Phase B: DDL commands without value literals
Migrate the five DDL commands at four entry words: drop (drop
table / drop column / drop relationship), add (add column /
add 1:n relationship), rename (rename column), change (change
column). The walker route now owns these end-to-end; chumsky
declarations remain unreachable for these inputs but stay
until Phase F.
Walker extensions:
- New node kinds: NumberLit (with optional content validator)
and Literal(&str) (verbatim byte sequence with word-boundary
lookahead — used for the `1` in `add 1:n …` so it surfaces
as `\`1\`` in the expected-set, matching the existing
parse_error_pedagogy contract).
- Flag (--name) terminal — Phase A stubbed; now wired to the
walker driver with consume_flag() in lex_helpers.
- Repeated combinator with optional separator and `min` floor.
Used by referential clauses (0..2 `on <delete|update>` runs)
and change-column flags (0..N --force-conversion /
--dont-convert; AST builder enforces mutual exclusion).
- Optional now propagates its inner's expectations as a
`skipped` field on the Matched result. Seq accumulates these
across children so the next failure's expected-set surfaces
the full union — closes the keyword-completion regression
(`add column ` must offer `to`, `table`, plus the table-name
identifier slot).
- Expectation::Ident gained a `source: IdentSource` field; the
parser-side bridge maps Tables/Columns/Relationships/Types
to the IdentSlot::expected_label strings ("table name",
"column name", …) so the existing completion engine's
schema-cache lookup still resolves.
- Walker error wording now includes "after `<consumed>`,
expected …" framing — matches the chumsky-side test
contract for structural errors mid-shape.
- AST-builder validation errors now propagate as
WalkOutcome::ValidationFailed (not the generic "AST builder
failed" fallback), so `change column … --force-conversion
--dont-convert` and repeated `on delete` clauses surface
their friendly catalog wording verbatim.
Grammar additions:
- src/dsl/grammar/shared.rs: type-name validator (TYPE_VALIDATOR
uses Type::from_str via parse.custom.unknown_type catalog),
qualified_column sub-grammar, referential action keyword
(`cascade`/`restrict`/`set null`/`no action`), repeated
on-clauses.
- src/dsl/grammar/ddl.rs: drop/add/rename/change CommandNodes
with inline shapes (per-use-site `role` annotations let the
AST builder discriminate parent vs child columns, etc.).
The four entry words each have one CommandNode whose `shape`
is a Choice across sub-forms.
Tests:
- 14 new walker-specific tests covering all DDL forms (bare
drop table, drop column with optional connectives, drop
relationship by name and by endpoints, add column with type
validator, rename column, change column with each flag form
+ mutual-exclusion check, add 1:n relationship minimal /
full, repeated-clause-twice rejection).
- Total: 819 passed, 0 failed, 1 ignored (was 805 / 1).
- cargo clippy --all-targets -- -D warnings clean.

ADR-0024 Phase A: walker framework + app-lifecycle commands
Stand up the unified-grammar tree walker alongside the existing
chumsky parser and migrate the eleven app-lifecycle commands
(quit, help, rebuild, save / save as, new, load, export, import,
mode, messages) end-to-end. The router in parse_tokens consults
the walker first; non-migrated commands still fall through to
chumsky.
Scope:
- src/dsl/grammar/{mod,app}.rs: Node enum (13 kinds), Word /
IdentSource / HintMode / HighlightClass / ValidationError /
CommandNode types, REGISTRY of the eleven app commands.
- src/dsl/walker/{mod,driver,context,outcome,lex_helpers}.rs:
scannerless byte-level walker, per-node-kind dispatch with
Choice/Seq/Optional backtracking, WalkContext (Phase B-D
schema fields stubbed), WalkOutcome with Match/Incomplete/
Mismatch/ValidationFailed.
- src/dsl/parser.rs: try_walker_route() runs first in
parse_tokens; bridge converts WalkOutcome to ParseError
preserving catalog wording (mode.unknown / messages.unknown
surface verbatim via friendly::translate). Legacy
try_parse_app_path_command deleted; chumsky's bare-keyword
app branches remain unreachable until Phase F sweep.
Walker design choices worth noting:
- mode <value> / messages <value> use Choice(Word, Word, Ident)
so known keywords appear in the expected-set; the trailing
Ident catch-all funnels unknown values into the friendly
validator that always errors with the catalog wording.
- save / save as is one CommandNode (Optional(Word("as"))) -
closes the round-5 "save Tab can't offer as" limitation
structurally.
- Path-bearing UX shipped per ADR-0024: BarePath terminates at
whitespace; paths with spaces use the (not-yet-wired) quoted
form. Existing tests pass on the new shape.
Tests:
- 28 new walker-specific tests in dsl::walker::tests covering
every app-lifecycle command, friendly-error wording for
mode/messages unknown values, trailing-garbage detection,
whitespace tolerance, and routing fall-through.
- Total: 805 passed, 0 failed, 1 ignored (was 777 / 1).
- cargo clippy --all-targets -- -D warnings clean.

add handoff-8: round 5/6 summary + ADR-0024 execution handoff
Round 5 + 6 testing + i18n sweep + thiserror migration +
ADR-0023 (direction) + ADR-0024 (accepted execution plan).
Frames the next session's primary task: execute ADR-0024
Phases A-F non-interactively. Spells out escalation criteria
("ADR doesn't cover this" not "I'm unsure which choice is
better"), per-phase commit checkpoints as the user
touchpoint, and the autonomous-by-default disposition the
user has explicitly requested.
Smoke test refreshed (empty hint wording, value-literal slot
hint, q removed, catalog-driven CLI error). Sharp-edges
section covers the design's traps (scannerless walker,
schema-aware parse, WalkContext writes, DynamicSubgrammar
expansion, Optional continuations closing the round-5 'save
Tab can't offer as' gap, IdentSource::Types replacing the
TYPE_SLOT_LABEL magic string, path-bearing UX change
requiring quoting for paths-with-spaces, hand-curated help
text staying out of grammar-derivation scope).

add ADR-0024: unified grammar tree execution plan (accepted)
Concrete specification for the direction in ADR-0023, landed during the round-6 design pass. Resolves all four rounds of open design questions: walker as single source of truth, scannerless terminal vocabulary (~8 building blocks), typed value slots with content validators, WalkContext for schema- aware narrowing from day one, WalkOutcome multi-purpose return, HintMode per-node, ranker as separate layer, static + dynamic sub-grammars, aliases as Word annotations, IdentSource taxonomy, six-phase per-command migration with chumsky and walker side-by-side during the transition. Key shifts from ADR-0023's sketch: - Lexer dissolves entirely. Walker operates on bytes directly. dsl/lexer.rs, dsl/keyword.rs go away in Phase F. - Schema-aware parse from day one (not phased). Typed value slots reject mis-shaped input at parse time with localised wording. Completion narrows per column type. - Sub-grammars: static (fn() -> Node) for composition; dynamic (fn(&WalkContext) -> Node) for schema-dependent expansion. No global named registry. - Path-bearing commands: BarePath becomes a routine non-whitespace terminal. Paths with spaces require quoting via StringLit (UX simplification, aligns with standard CLI convention). - 13-node taxonomy: Word, Punct, Ident, NumberLit, StringLit, BlobLit, Flag, BarePath, Choice, Seq, Optional, Repeated, DynamicSubgrammar. Migration plan: Phase A (walker scaffolding + app-lifecycle commands), Phase B (DDL without value literals), Phase C (create table), Phase D (data commands with full schema awareness -- the design's central claim landing), Phase E (replay), Phase F (delete chumsky + lexer + legacy parser modules, simplify catalog). Estimated ~4 sessions total. Also: rename ADR-0023 from 0023-proposed-unified-grammar-tree.md to 0023-unified-grammar-tree.md (git mv preserves history) and update its status to reflect the direction-accepted-but- superseded-for-execution-detail relationship with ADR-0024. Index updated. |

hint: replace misleading "null true false" suggestions at value slots
At value-literal slots (`insert into T values (`, `update T set
col=`, `where col=`, comma positions) the expected-token set
contains null/true/false/number/string-literal. The completion
engine was surfacing the three keyword candidates as Tab options
— actively misleading because the user is usually about to enter
a number, quoted text, or date, and seeing "null true false"
implies those are *the* options. User report (round-6 testing):
"especially not when I'm trying to insert a datetime value and
don't know the correct format for the literal".
Fix: detect the value-literal slot by its expected-set
fingerprint. Suppress Tab candidates at empty prefix. Surface a
prose hint listing all literal forms with format examples
('YYYY-MM-DD' for dates, 'YYYY-MM-DDTHH:MM:SS' for datetimes).
Once the user starts typing a prefix (n / tr / fa), normal
keyword completion still applies.
Schema-aware narrowing (show ONLY the datetime format at a
datetime column) waits on ADR-0023.
Tests: 769 -> 777 passing (+8). Clippy clean.

add ADR-0023 (proposed): unified declarative grammar tree
Captures the architectural critique surfaced during round-5 manual testing — that adding a keyword or command currently requires edits in 7-10 files across parser, completion, usage registry, catalog, and tests — and the proposed direction: a single declarative trie registry that drives parse, completion, highlight, and usage rendering from one source. Status: Proposed. Not yet accepted. Filename carries the `-proposed-` segment so status is visible at directory-listing time; rename to `0023-unified-grammar-tree.md` on acceptance. Estimated cost: ~4 sessions, per-command migration. Why not now: feature backlog and bearable scatter cost. Right moment to execute when backlog quiets or scatter cost becomes visibly painful. |

remove q quit alias
`q` was introduced in round-5 as a peer Keyword variant alongside `quit`. Per ADR-0023's "alias miss" critique, that was the wrong shape — it surfaced `q` as a standalone command in completion (only one of its kind), and required parallel parser + usage + catalog + test entries. Drops the Keyword variant entirely; if this ever needs to come back, it should arrive as an alias annotation per ADR-0023, not as a peer keyword. Tests still 769 passing. |

round-5 follow-up r2: migrate all thiserror Display attributes to catalog
Completes the i18n sweep started in the previous commit. All
remaining hand-rolled user-facing English strings inside
thiserror #[error(...)] attributes have been moved into the
catalog. Drops the thiserror dependency entirely.
Twelve error types migrated:
- dsl::action::UnknownAction → parse.custom.unknown_action
- dsl::parser::ParseError → parse.error_wrapper + parse.empty
- dsl::value::ValueError → value.{type_mismatch,format}
- persistence::csv_io::CsvError → persistence.csv.*
- persistence::mod::PersistenceError → persistence.{io,encode}
- persistence::yaml::YamlError → persistence.yaml.*
- persistence::migrations::MigrateError → persistence.migrate.*
- project::lock::LockError → project.lock.*
- project::naming::NamingError → project.naming.*
- project::naming::UserNameError → project.user_name.*
- project::mod::ProjectError → project.{path_not_found,...}
- project::mod::SafeDeleteError → project.safe_delete.*
- archive::ArchiveError → archive.*
- cli::ArgsError → cli.*
- db::DbError → db.error.*
Pattern per type: drop thiserror::Error derive, write manual
Display calling crate::t!(), keep #[from] semantics via
explicit From impls, override Error::source() where applicable
so #[source]-style chaining is preserved.
Why this matters (user rationale): "fine to have fallbacks for
errors that are purely technical, but lift the output to a
place where it can be localized later and where an adjustment
with friendly text is easily possible if any of them become
part of the happy path." All surface strings now live in
en-US.yaml and can be reworded or localized without touching
Rust source.
Tests: 769 passing, 0 failed, 1 ignored. Clippy clean with
-D warnings. Cargo.toml: drop thiserror = "2.0.18".

round-5 follow-up: completion + i18n sweep
Four user-reported gaps from the round-4 testing pass:
1. Empty-prompt hint reworded from "(no active hint)" to
"Type a command — press Tab for options, `help` for a
list" (6 snapshots updated to reflect 80-col truncation).
2. App-lifecycle commands (quit/q, help, rebuild, save/save as,
new, load, export, import, mode, messages) now flow through
the DSL parser:
- 15 new keywords + catalog token entries
- new Command::App(AppCommand) AST with 11 variants
- parse-first dispatch in submit() (app commands work in
both simple and advanced modes)
- pre-chumsky source-slice for `export <path>` /
`import <zip> [as <target>]` mirrors the replay precedent
- UsageEntry registry entries so parse errors surface
relevant usage templates
- `mode <bad>` / `messages <bad>` use try_map for the
friendly "unknown mode/messages" wording
3. DSL completion gaps:
- `1:n` surfaces as a composite candidate at `add `
- --all-rows / --create-fk / --force-conversion /
--dont-convert surface as new CandidateKind::Flag
candidates (coloured with tok_flag in hint panel)
- filter_clause .labelled() wrap removed so chumsky's
expected-set surfaces the constituent options
4. Hardcoded user-facing strings migrated to catalog:
- 4 parser custom errors (incl. the known "tables need at
least one column" wart)
- UnknownType Display now via parse.custom.unknown_type
- UI panel titles + mode labels (Output / Hint / SIMPLE /
ADVANCED / Advanced:)
- app.rs cascade rendering (action labels + summary)
- runtime --resume CLI stderr
- db.rs change-column diagnostic tables (7 headers + 3
wrapper summaries + force-conversion hint)
Tests: 765 → 769 passing, 0 failed, 1 ignored (same doctest
as before). Clippy clean with -D warnings.
Deferred:
- ~25 thiserror #[error] attributes still hand-rolled
(DbError, ArgsError, ArchiveError, PersistenceError,
LockError). Tracked separately.
- DSL/SQL relationship in advanced mode — clarified
implicitly via parse-first dispatch; broader ADR
amendment to follow.
- Post-complete-parse completion gap (e.g. `save ` Tab
can't offer `as` because `save` parses bare; same shape
as `--create-fk` after a complete `add relationship`).

ADR-0022 follow-up r4: column-type completion
Round-4 user finding: typing `(de` at a column-type slot
showed the parser's "unknown type 'de'" error and Tab did
nothing — completion was blind to the type vocabulary
entirely.
Root cause: type names are NOT in the Keyword enum (ADR-0020
§2 — they remain identifiers, validated by Type::from_str),
so the keyword-iter path in candidates_at_cursor missed
them. The schema-identifier path also missed them (they're
not in the schema cache).
Fix: when the parser's expected-set contains the `"type"`
label (from `ident_inner().labelled("type")` inside
`type_keyword`), produce candidates from `Type::all()`
filtered by the partial prefix. Centralised as
`TYPE_SLOT_LABEL` constant so the parser and the completion
engine agree on the magic string.
Candidates appear in `Type::all()` declaration order
(text/int/real/decimal/bool/date/datetime/blob/serial/
shortid) — matching ADR-0005's pedagogical grouping. Coloured
as Keyword (purple) since type names are closed-set
grammar, not user content.
Verified end-to-end:
- `(de` → ["decimal"] (single match → Tab inserts with space)
- `(da` → ["date", "datetime"] (multi → cycles)
- `(sh` → ["shortid"]
- `(` → all 10 types in declaration order
- `(var` → [] (no Tab candidates; parser custom error fires on submit)
Tests: 760 passing, 0 failing, 1 ignored (755 baseline +5
new type-slot cases). Clippy clean.

ADR-0022 follow-up r3: identifier colour, NewName hint, "Next:" wording, "type" label
Three fixes from a third round of real testing. 1. **tok_identifier vivid (round-3 #1).** The cool grey-blue from r2 was still too close to theme.fg to register as distinct. Bumped to cyan-teal (#56B6C2 dark / #0F6B76 light) — identifiers are the user's most "special" content and now read that way against keywords (purple), numbers (orange), strings (green), and flags (amber). 2. **"Type a name" hint at NewName slots (round-3 #2).** New `completion::typing_name_at_cursor(input, cursor)` returns `Some(TypingName)` when the cursor sits at — or inside — an `IdentSlot::NewName` position. It probes by substituting a single-letter placeholder identifier and re-parsing to discover what the parser would expect AFTER the name; the hint then reads "Type a name, then `(`" instead of the technical "next: `(`" that surfaces once the partial identifier has been consumed by the live parser. When the probe yields nothing useful (custom errors with empty expected, or a complete-on-substitute case), falls back to "Type a name". New catalog keys hint.ambient_typing_name and hint.ambient_typing_name_then. Wired into ambient_hint between the candidate-list and invalid-ident checks. 3. **"Next:" instead of "expected:" wording.** "Expected" read as a leaked diagnostic; "Next:" is shorter, conversational, and consistent with the action-oriented voice of "Submit with Enter" and "Type a name". Hint sentences now also start capitalised (Submit/Next/Type/No-such), per the user's Capital-T-on- "type a name" preference. 4. **type_keyword labelled "type".** Without a label, the `select_ref!` over an Identifier token produced `RichPattern::SomethingElse`, which rendered as the meaningless "something else" in the hint after `(`. Labelled now: error reads "Next: type" — terse but honest. The label is applied BEFORE try_map (not after, not via as_context) so the existing custom-error wording for unknown types ("unknown type 'varchar' (expected one of: …)") still surfaces unchanged. Tests: 755 passing, 0 failing, 1 ignored (no net change — +5 typing_name cases, -0 net since one test was reworded for capitalisation rather than added). Clippy clean. Smoke probe verifies: "add column to table T: " → "Type a name, then `(`"; "add column to table T: Name (" → "Next: type"; "show data Custp" → "No such table: `Custp`"; valid input → "Submit with Enter". Note for next testing round: parser-side custom errors (e.g. the "tables need at least one column" message that fires for `create table Customers `) still read in lowercase — they're hand-written in parser.rs source rather than via the catalog. If the lowercase "tables need…" intrusion bothers you, easy follow-up. |

ADR-0022 stage 8 follow-up r2: completion UX fixes from real testing
Two concrete behaviour changes from the user's second testing
round:
1. **Single vs multi commit paths.** Previously every Tab,
even single-candidate, created a memo so Esc/Backspace could
undo. The downside: with one candidate, repeated Tab "cycled"
through the same item invisibly — looked stuck. Now:
- Single candidate → insert with trailing space, no memo.
The user can keep typing or hit Tab again to fresh-complete
at the new cursor. (Trade-off: Esc/Backspace no longer
whole-span undo for unique completions; the user accepted
this for the chained-Tab fluency.)
- Multi candidate → insert WITHOUT trailing space, create
memo for cycling. The natural commit gesture is space —
pressing it clears the memo and inserts the space normally,
producing "<chosen> " ready for the next position.
The "stuck on unique" symptom goes away, and the missing
trailing space on multi-Tab signals "you're picking; press
space when you're done" without needing modal affordances.
2. **Keyword candidates in grammar order.** Dropped the
alphabetical sort in `describe_expected` in favour of
chumsky's native source-order traversal of `or_not`/`choice`
chains — empirically this matches the canonical command
shape. Result: `add column ` now offers `to` before
`table` (as `add column [to] [table] <Table>:…` reads),
not `table` before `to` which previously suggested the
nonsensical `add column table to ...`. Identifiers still
alphabetised within their group; entry-keyword fallback
for the no-prefix case stays alphabetical (no source order
when 10 separate command branches).
Tests: 750 passing, 0 failing, 1 ignored (747 baseline →
+3 net: replaced single-candidate Esc/Backspace tests with
new multi-candidate variants; added the unique-Tab-chains-
naturally case that drove the round-2 fix; kept the
keywords-in-grammar-order test updated to assert
`to`/`table`/identifiers ordering).

ADR-0022 stage 8 follow-up: fixes from real-app testing
Three fixes from the user's testing run, plus an investigation note on a fourth. #4 Sticky hint during cycling. The previous code recomputed candidates_at_cursor at the post-Tab cursor position, which made the panel whiplash through "what comes next at the new cursor" between cycles. ambient_hint now short-circuits to the memo's stored candidate list while the memo is alive — so Tab Tab Tab keeps showing the same list with the selection moving, then snaps to the post-Tab ambient state once any non-Tab key clears the memo. #2 Candidate ordering and kind-coloured rendering. New `Candidate { text, kind: Keyword|Identifier }` carries the classification through completion, last-completion memo, and ambient-hint payload. candidates_at_cursor now sorts keywords first (alphabetical), identifiers second (alphabetical), and the hint-panel renderer colours keywords in `tok_keyword` and identifiers in `tok_identifier`. Keyword-vs-identifier name collisions resolve in favour of the keyword (rare; the user can still address their table via different syntax). #3 tok_identifier no longer matches theme.fg. Identifiers in the input pane now render in a distinct cool grey-blue (dark) / dark steel-blue (light), so they stand out from prose-like default text without competing with keyword purple. Same colour drives the identifier candidates in the hint panel for visual consistency input ↔ hint. Limitation worth knowing: "keywords first, alphabetical" is not the same as grammatical order. For "add column " the hint shows `table to` not `to table` — chumsky's expected-set doesn't preserve combinator-source order, and encoding it in the registry adds maintenance overhead the fix doesn't cleanly justify. Marked for future revisit if it bites. #1 (Tab does nothing on "add column ") — not reproduced through App::update. The internal logic works correctly: "add column " + Tab inserts "Customers ", second Tab cycles to "Orders ", third to "Thing ". The most likely explanation is a stale binary or a terminal-level event intercept (tmux focus, kitty-keyboard protocol differences, etc.) — needs user verification with a fresh build. Tests: 747 passing, 0 failing, 1 ignored (744 baseline → +3: 2 new completion-ordering cases including the keyword-wins-on-name-collision edge, plus 1 hint-mid-cycle sticky test). Clippy clean. |

ADR-0022 stage 8e: invalid-identifier detection + hint variant
Per the user's #5: "if our candidate selection works correctly, then entering a character that removes all matches is the same as entering an invalid token." Closes the loop between schema cache (8c/8d) and live error feedback (4). New `completion::invalid_ident_at_cursor(input, cursor, cache)` returns `Some(InvalidIdent { range, found, slot })` when: - the cursor is on a partial identifier-shaped token; - the parser's expected-set at the start of that token contains a known-set IdentSlot (TableName / Column / RelationshipName); - no schema entry across those slots prefix-matches the typed text. `render_input_runs` extended to take a `&SchemaCache` and overlay the invalid-identifier range with `tok_error` — same visual treatment as the parse-error overlay (4), unified red signal regardless of which detector fires. `ambient_hint` extended to surface `hint.ambient_invalid_ident` when invalid_ident_at_cursor returns Some — wording "no such {kind}: `{found}`" mirrors ADR-0019's engine-error voice for consistency. Catalog + KEYS_AND_PLACEHOLDERS declaration added; validator passes. Render priority: candidates win over invalid-ident (if any schema match exists for the partial prefix, the state is "in-progress completion" not "invalid"). Falls through to the existing parse-error/incomplete/Valid framings otherwise. NewName slots are filtered out at the source — typing into a "user invents this name" position is never invalid (per `IdentSlot::completes_from_schema`). Tests: 744 passing, 0 failing, 1 ignored (738 baseline → +6: 5 invalid_ident_at_cursor cases covering unknown-prefix-fires, prefix-match-doesn't-fire, NewName-immune, no-cursor-token, keyword-slot-immune; plus 1 ambient_hint integration test). Clippy clean. This closes ADR-0022. Stages 1-8e together deliver the ambient-typing-assistance feature: token highlighting, error overlay, hint panel ambient, hint panel multi- candidate display with scroll markers, Tab/Shift-Tab cycling with one-keystroke Esc/Backspace undo, schema-aware identifier completion, and invalid-identifier live feedback. Total stage-8 footprint: 5 commits, ~1600 lines. |

ADR-0022 stage 8d: schema cache refresh wiring
New `AppEvent::SchemaCacheRefreshed(SchemaCache)` event + App handler that stores it on `app.schema_cache`. Runtime helper `refresh_schema_cache(database, event_tx)` fetches table / column / relationship names via the `list_names_for` worker request (added in stage 7) and posts the assembled cache. Wired into every site that already posts `TablesRefreshed`: - `seed_initial_tables` (initial project load). - Project-switch path in `handle_project_switch`. - `RebuildSucceeded` path. - Post-DDL path (`spawn_command`). - Post-replay path. Result: schema-aware identifier completion (added in 8c) becomes live — Tab on `show data ` offers the actual table names from the current project, `drop column from T: ` (or similar) offers existing columns, etc. The cache stays fresh across DDL and rebuild without per-keystroke worker round-trips (one refresh per schema-mutating action is amortised across many subsequent keystrokes). Best-effort: a failed `list_names_for` for any individual slot kind leaves that field empty in the cache rather than suppressing the whole refresh — partial completion beats no completion. Tests: 738 passing, 0 failing, 1 ignored (unchanged total — this stage is wiring, not new test surface; the synthetic-cache tests from stage 8c remain the regression net for the completion logic itself). Clippy clean. |

ADR-0022 stage 8c: IdentSlot propagation + SchemaCache API
`IdentSlot` gains `expected_label()` and the round-trip
`from_expected_label()`. The four slot kinds map to the
user-facing labels "identifier" (NewName), "table name",
"column name", "relationship name".
`ident_ctx(slot)` now actually applies `slot.expected_label()`
as the chumsky label (was documentation-only after stage 6).
Parser errors and the hint panel's "expected: …" prose now
read with the slot-specific name: "expected table name"
instead of the generic "expected identifier". One parser
test updated accordingly; the four catalog `parse.token.*`
keys are unaffected (the slot labels are a parallel surface).
New `completion::SchemaCache { tables, columns,
relationships }` struct + `for_slot(slot) -> &[String]`
accessor. Empty by default; runtime wiring lands in a
follow-on substage. NewName slots return `&[]`
unconditionally.
`candidates_at_cursor` extended to accept `&SchemaCache`:
when the parser's expected-set includes a slot label,
schema candidates from the cache are added alongside the
keyword candidates. Both sources are then prefix-filtered,
combined, sorted, deduplicated. App::schema_cache field
threaded into both the App-side completion paths and the
ambient_hint computation in ui.
Tests: 738 passing, 0 failing, 1 ignored (730 baseline →
+8: 2 IdentSlot label round-trip tests, 6 completion-with-cache
cases covering table/column/relationship slots, prefix
filtering, empty cache, and NewName-no-candidates).
Clippy clean.
User-visible: identifier completion infrastructure is in
place but the cache is always empty — runtime wiring (the
next substage) will populate it on project load and after
successful DDL, at which point Tab on identifier slots
starts offering schema names.

ADR-0022 stage 8b: hint panel candidate list with scroll markers
Refactor `ambient_hint` to return a richer enum:
- `Prose(String)` — the existing single-line hint (Valid /
incomplete-with-no-keywords / definite-error states);
- `Candidates { items, selected }` — multi-candidate (or
single-candidate) keyword completion at the cursor.
When `candidates_at_cursor` returns Some, the new
`Candidates` variant wins over the prose framing — the
candidate list is more actionable than "expected: `data` or
`table`". `selected` tracks the live `LastCompletion` memo's
selection_idx for the renderer to highlight.
`render_candidate_line` (new helper in ui.rs):
- All items fit → render space-separated; selected item
rendered bold + theme.fg, others theme.muted.
- Overflow → window centred on the selected item (or
item 0 with no selection); `< ` / ` >` markers at the
edges (per the user's #2). Window expands right-first
then left-first to use available width.
- Returns `Line<'static>` (items cloned into spans) so the
caller doesn't fight lifetimes between the
AmbientHint::Candidates payload and the rendered Line.
Updated callers in ui.rs and input_render tests for the new
signature. Added `ambient_hint_with_memo_carries_selected_index`
test asserting the renderer-side `selected` plumbing.
Tests: 730 passing, 0 failing, 1 ignored (728 baseline →
+2 net: -3 reworked + 5 new candidate-related cases).
Clippy clean.
Stage 8c will plumb identifier completion (schema cache +
candidate fetch from worker on demand or pre-cache) and add
the invalid-identifier hint variant.

ADR-0022 stage 8a: non-modal keyword completion + Esc/Backspace undo
Per the user's framing decision: there is no "completion
mode." Tab is just an action that consumes whatever is
expected at the cursor, and the existing always-on hint
panel (stage 5) tells the user what's available.
New `completion` module: `candidates_at_cursor(input,
cursor)` returns a `Completion { replaced_range,
partial_prefix, candidates }` based on the parser's
expected-token set at the cursor position. Filters to bare
keyword candidates only (no punctuation, no descriptive
labels), narrowed by the typed prefix (case-insensitive).
`LastCompletion` memo struct on `App::last_completion`
carries the cycle state: inserted_range, original_text,
candidates, selection_idx. Wrap-around forward/backward
indices.
App key handling (added before the existing matcher):
- Tab → cycle forward if memo present; else insert first
candidate; create / advance memo.
- Shift-Tab → cycle backward if memo present; else
insert last candidate (alphabetically) so the user can
jump to the end without cycling through everything.
- Esc / Backspace while memo alive → restore
original_text in inserted_range, place cursor at the
pre-Tab position, clear memo.
- Any other key → clear memo, then process normally.
The user's symmetry preference was load-bearing here:
"insert with one keystroke, remove with one keystroke."
Both Esc and Backspace honour that — multiple Tab cycles
collapse into one undo. Documented inline.
A single-candidate completion still creates a memo so
Esc/Backspace can undo it. Multiple Tabs in a row cycle
through the candidate list with wrap-around at both ends
(per the user's #2).
Tests: 728 passing, 0 failing, 1 ignored (705 baseline →
+23: 13 completion module + 10 app integration tests
covering Tab, Shift-Tab, cycling, wrap-around, Esc-undo,
Backspace-undo, multi-Tab-then-Esc, memo invalidation by
typing or cursor movement). Clippy clean.
Stage 8b will add multi-candidate hint-panel rendering
with scroll markers (`<` `>`) per the user's #2. Stage 8c
will plumb in identifier completion + invalid-identifier
detection.

ADR-0022 stage 7/8: schema query plumbing
Add `Request::ListNamesFor { slot, reply }` and the public
`Database::list_names_for(slot)` method. The completion
engine in stage 8 calls this on Tab when the cursor sits
on an identifier-typed slot.
Worker dispatch:
- TableName → user tables (filters __rdbms_*).
- Column → distinct column names across all user tables
(v1 simplification per the stage 6 IdentSlot note: no
table-context binding; the schema-completion engine in
stage 8 may refine).
- RelationshipName → relationship names from the
__rdbms_playground_relationships metadata table.
- NewName → short-circuited at the public method (no
worker round-trip).
Names are returned alphabetised + deduplicated. Filters
respect ADR-0002 — internal __rdbms_* tables never reach
the completion menu (covered by a regression test).
Tests: 705 passing, 0 failing, 1 ignored (700 baseline →
+5 list_names_for cases). Clippy clean.
Stage 8 wires this into the App as a Tab-triggered
completion mode. Note for the next session: stage 8 is by
far the largest of the eight stages — it touches App state
(completion mode), event routing (Tab/arrow/Enter/Esc/letter
behaviour while in completion mode), hint-panel render
variant, candidate filtering, integration tests. Several
fine-grained UX decisions (cursor position after accept,
panel height when candidate list overflows, what closes
the mode) want explicit user input rather than agent
guesswork. See "Stage 8 open questions" in the next
handoff for the list.

ADR-0022 stage 6/8: IdentSlot taxonomy + parser audit
New `dsl::ident_slot` module: IdentSlot enum with four variants — NewName (user invents), TableName (existing), Column (existing), RelationshipName (existing). Plus `completes_from_schema()` accessor for the completion engine in stage 8. Deliberate v1 simplification vs. ADR-0022 §8: no TableRef binding for Column. The completion engine in stage 8 will either union all columns or determine the table from the consumed prefix heuristically. The TableRef wrinkle returns if/when stage 8 needs it. Parser audit: renamed bare `ident()` → `ident_inner()` (now private-by-convention) and introduced `ident_ctx(slot)` wrapper. Every command parser combinator was audited and each `ident()` call site replaced with the appropriate `ident_ctx(IdentSlot::…)`: - create_table table-name → NewName - drop_table → TableName - add_column → TableName + NewName - drop_column → TableName + Column - rename_column → TableName + Column + NewName - change_column → TableName + Column - show_data / show_table → TableName - insert column-list → Column; insert table → TableName - update set-LHS → Column; update target → TableName - delete target → TableName - where-clause LHS → Column - relationship `as <name>` → NewName - drop relationship by name → RelationshipName - qualified_column → TableName + Column - with_pk_clause spec name → NewName The slot tag is currently documentation-only — the wrapper ignores it and returns ident_inner() unchanged. The audit's value is ensuring every call site has explicit intent recorded co-located with the parser combinator. The completion engine in stage 8 will start consuming the slots either by re-parsing with awareness or by an explicit parser-side propagation refactor. Tests: 700 passing, 0 failing, 1 ignored (698 baseline → +2 IdentSlot enum tests). Clippy clean. Stage 7 plumbs schema queries through the worker thread (ListNamesFor) so stage 8's completion engine has data. |

ADR-0022 stage 5/8: hint panel ambient typing assistance
ParseError::Invalid gains an `expected: Vec<String>` field —
the human-rendered names of the patterns chumsky was looking
for at the failure point (`\`create\``, `identifier`, etc.).
Empty for custom errors, which have no expected-set framing.
Populated by a new `describe_expected()` helper in parser.rs
that humanise() also delegates to (eliminates duplication).
`input_render::ambient_hint(input) -> Option<String>` returns
the hint-panel content per ADR-0022 §6:
- empty input → None (caller falls back to panel.hint_empty);
- Valid → t!("hint.ambient_complete") ("submit with Enter");
- IncompleteAtEof → t!("hint.ambient_expected", expected = …)
listing the parser's expected next tokens, oxford-joined;
- DefiniteErrorAt → t!("hint.ambient_error_with_usage", …)
composing the parse-error message with the matching
parse.usage.* template if a known entry keyword was
consumed, else the bare message.
Catalog gains the three hint.ambient_* keys + validator
declarations.
ui::render_hint_panel resolution order:
1. explicit app.hint (modal contexts) wins;
2. simple-mode + non-empty input → ambient_hint;
3. fallback to panel.hint_empty.
Advanced mode (persistent + one-shot `:`) bypasses ambient
hinting per ADR-0022 §12.
Snapshot: highlighted_input_all_token_classes rebaselined
because the hint panel now displays an ambient hint instead
of the empty placeholder when input is non-empty.
Tests: 698 passing, 0 failing, 1 ignored (693 baseline →
+5 ambient_hint cases). Clippy clean.
Stage 6 introduces the IdentSlot taxonomy + parser audit so
identifier-typed slots can yield schema-aware completion
candidates in stage 8.

ADR-0022 stage 4/8: render-time parse + error overlay
Add `classify_input(&str) -> InputState` that returns one of
{Empty, Valid, IncompleteAtEof, DefiniteErrorAt(byte)}.
The renderer uses this to overlay tok_error on the failing
token of mid-typed input that can never be valid.
ParseError::Invalid gains an `at_eof: bool` field populated
by `into_parse_error`:
- structural failures: at_eof = found.is_none()
(chumsky's own "ran out of input" discriminator);
- custom errors from try_map: at_eof = true,
conservatively.
The conservative custom-error classification is a deliberate
under-highlighting bias. It means three classes of error
currently DO NOT get a live red overlay (only on submit):
- "tables need at least one column" (correct: this is
genuinely an incomplete state — adding `with pk ...` fixes it);
- "unknown type 'varchar'" (sub-optimal: should overlay);
- "--force-conversion and --dont-convert are mutually
exclusive" (sub-optimal: should overlay).
The trade-off is documented inline on the at_eof field. A
future refinement could carry an explicit definite/incomplete
tag through Custom errors (would change RichReason::Custom's
payload from String to a typed value).
render_input_runs now applies the overlay on the failing
token's run before injecting the cursor. Tokens after the
error keep their lex-class colour — fixes one thing at a
time per ADR-0022 §4. Lex errors continue to render in
tok_error from stage 2.
Pattern-matches on ParseError::Invalid throughout the
codebase use `..` and are unaffected; only the two
constructions in parser.rs needed updating.
Tests: 693 passing, 0 failing, 1 ignored (683 baseline →
+10: 7 classify + overlay tests, +1 adapted full-command
test, +2 valid-vs-incomplete coverage). Clippy clean.
Stage 5 lights up the hint panel as the verbose-feedback
surface — needs the InputState classifier from this stage.

ADR-0022 stage 3/8: simple-mode echo lines highlighted
Lift `dsl::ECHO_PREFIX = "running: "` as a public const,
with a unit test asserting `t!("dsl.running", input = "")`
matches it. The catalog template is now contracted to equal
`format!("{ECHO_PREFIX}{input}")` — a translator changing
the prefix breaks the test.
Add `input_render::lex_to_runs(input, theme)` — a
cursor-less variant of `render_input_runs` for use cases
(echo lines, future hint panel) that need token-class
colouring without an inverted cursor.
ui::render_output_line: when the line is an Echo submitted
in Simple mode, peel the prefix and re-tokenise the rest
through lex_to_runs, rendering each token at its class
colour. Advanced-mode echoes and any echo whose body
unexpectedly lacks the prefix fall through to the plain
rendering.
Tests: 683 passing, 0 failing, 1 ignored (682 baseline →
+1 echo_prefix_matches_catalog_template). Clippy clean
(uses let-chain to keep the if condition flat).
Stage 4 adds render-time parse + error overlay so the
failing token in mid-typed input lights up in the error
colour.

ADR-0022 stage 2/8: input panel — token-class highlighting
New `input_render` module with `render_input_runs(input, cursor_byte, theme) -> Vec<StyledRun>`. Lexes the input, assigns each token its `theme.token_color`, preserves whitespace gaps as `theme.fg` runs, and injects the cursor by splitting the run that contains it into before/under/after sub-spans (under marked Modifier::REVERSED). End-of-input cursor is an empty-range sentinel rendered as an inverted space. ui::render_input_panel switches over EffectiveMode: simple mode goes through render_input_runs + a small runs_to_spans helper that borrows from the input string; advanced modes (persistent + one-shot `:`) keep the previous plain before/under/after rendering since the DSL lexer doesn't speak SQL (ADR-0022 §12). Multi-byte UTF-8 in string literals is handled by walking to the next char boundary when splitting the cursor run, mirroring the previous renderer. Tests: 682 passing, 0 failing, 1 ignored (672 baseline → +10: 9 input_render unit tests covering each token class, cursor placements, multi-byte, full-command shape; +1 new "all token classes" UI snapshot). Clippy clean. Caveat (noted inline in the new snapshot test): the TestBackend/render_to_string path records text symbols only, not ratatui style. The new snapshot is therefore a text-layout regression net; the unit tests in input_render::tests are the authoritative regression net for colour mappings. Stage 3 wires the same colouring into simple-mode echo lines in the output panel. |

ADR-0022 stage 1/8: theme token-class colour fields
Add seven `tok_*` Color fields to Theme — keyword, identifier, number, string, punct, flag, error — populated in both dark and light themes. WCAG-AA contrast against each theme's bg. Identifier and punct sit close to fg/muted so dominant content reads quietly; literals + flags get warm accent tones; keyword takes a cool accent (purple) distinct from the mode-banner blue. tok_error reuses the existing error palette so lex-error tokens read consistently with [error] lines elsewhere. New helper Theme::token_color(&TokenKind) -> Color maps each token kind to its display colour. Tests: 672 passing, 0 failing, 1 ignored (668 baseline → +4 theme tests). Clippy clean. Pure addition; no existing render path uses these yet. Stage 2 wires them into the input panel. |

ADR-0022: ambient typing assistance (unifies I3 + I4)
Replaces the originally-planned separate ADRs for syntax highlighting (I4) and tab completion (I3) with a single unified design. The framing: colour, hint panel, and Tab are three answers to the same question — what does the user need to know mid-typing? — and planning them separately produces three loose pieces that drift apart. Three mid-typing states (valid-so-far / definite-error / incomplete-but-plausible) drive four layered channels: token-class colour and parse-error overlay (silent, always on), hint panel ambient and Tab-triggered completion mode (verbose, in the existing hint panel — no floating popups). Schema-aware from day one via an IdentSlot taxonomy in the parser (NewName / TableName / ColumnIn(TableRef::Earlier(N)) / RelationshipName); every existing ident() call gets audited and tagged. Completion candidates come from chumsky's expected-token-set for keyword slots and from a new worker request (ListNamesFor) for identifier slots. Implementation lands in 8 green-after-each commits: theme colours; input panel highlighting; echo line highlighting; render-time parse + error overlay; hint panel ambient; identifier-slot taxonomy + parser audit; schema query plumbing; completion mode + key bindings. Estimated 1500-2500 lines across the eight stages. Out of scope (deliberately): inline ghost text (could return as a "most-likely" affordance later — fish-shell style), fuzzy matching, punctuation completion, user-customisable keybindings, SQL highlighting in advanced mode (waits on Q4). |

ADR-0021 implementation: per-command usage templates in parse errors
New `dsl::usage` module: registry pairing each command's
entry-keyword with a `parse.usage.*` catalog key.
`matched_entry()` resolves the entry keyword from the
consumed token prefix; multi-entry families (add, drop,
show) return all matching keys.
Catalog: new `parse.usage.<command>` keys (one per command),
`parse.token.{keyword,punct,...}` vocabulary (one per
Keyword/Punct variant + token-class labels + LexError
kinds), and `parse.available_commands` for the no-prefix
fallback. Catalog grows ~60 entries.
Validator: extended KEYS_AND_PLACEHOLDERS; new completeness
test asserts every Keyword and Punct variant has its
`parse.token.*` entry.
`app::dispatch_dsl` rewritten to compose three blocks per
ADR-0021 §2: caret + structural/custom error + usage block
(or available-commands fallback per §5). Caret math fixed
to use original-input byte position rather than
trimmed-input position (the lexer no longer trims before
lexing). Three pre-existing app tests adjusted to look
across all error lines instead of `output.back()` (the
usage block is now the last line).
`dsl::usage::matched_entry` uses `<=` rather than `<` for
position comparison so custom errors raised by `try_map`
(whose span starts at the first consumed token) still
resolve to the entry keyword.
Tests: 668 passing, 0 failing, 1 ignored (650 baseline →
+18: 8 usage + 1 token-vocab completeness + 9 new
integration tests in tests/parse_error_pedagogy.rs
covering create/add/drop/show/frobulate/update/insert
cases). Clippy clean.

ADR-0020 implementation: lexer + parser refactor over &[Token]
New `dsl::keyword` module: macro-driven Keyword and Punct enums (single source of truth — enum, lex-side mapping, catalog-key derivation generated from one declaration). New `dsl::lexer` module: tokenizer producing a span-tagged Vec<Token>. Always succeeds; lex-shape errors (unterminated string, unrecognised character, malformed flag) embed as TokenKind::Error tokens so I4 can highlight invalid input uniformly. Parser refactored from `Parser<'a, &'a str, ...>` to `Parser<'a, &'a [Token], ...>`. All 50+ existing parser unit tests ported and passing; aggregation across `choice` now works as designed (e.g. `add` → "expected `1` or `column`", `drop` → "expected `column`, `relationship`, or `table`", `frobulate Customers` lists all ten command-entry keywords). Custom `try_map` content errors (unknown type, mutually-exclusive flags, "with pk needs at least one column", "specified twice") preserved. `replay` bare-path UX kept via the source-slice special case from ADR-0020 §6 (~10 lines, documented inline). Tests: 650 passing, 0 failing, 1 ignored (610 baseline + 40 new lexer/keyword tests). Clippy clean. |

ADR-0020 + ADR-0021: tokenization layer and parse-error pedagogy (H1a)
ADR-0020 amends ADR-0001 with a two-phase parse: a lexer
producing a span-tagged token stream, then chumsky over
&[Token]. Single source of truth for keywords and punct via
a define_keywords!/define_punct! macro pattern. Parser
contract committed for I3 (queryable expected-token-set)
and I4 (lexer always succeeds, Error tokens for invalid
input). Includes an honest history note: the no-lexer shape
in dsl/parser.rs arose incrementally without ADR-level
deliberation against the known H1a/I3/I4 requirements; this
ADR corrects that.
ADR-0021 builds on ADR-0020 to close the H1a gap: a
per-command UsageEntry registry keyed off entry-keyword,
with parse errors rendered as caret + structural error +
matching usage template(s). Multi-entry families (add,
drop, show) render together. New catalog sections under
parse.usage.* (per-command grammar) and parse.token.*
(single-token vocabulary). Zero-prefix case ("frobulate
Customers") falls back to an "available commands:" framing.
Anchor-phrase compliance preserved.

Handoff doc for end of 2026-05-09 (#6)
Documents this session's work and the recommended next move:
## Session totals
- 11 commits since handoff-5
- 534 → 610 tests passing (+76)
- Release binary 7.2 → 7.8 MB
## What landed
- All four non-CI items from handoff-5's Independent Work
list: B2 (int→bool tests), B1 (help update), A2 (engine-
vocabulary audit), A3 (replay command)
- ADR-0019 fully implemented end-to-end:
- Friendly-error layer + i18n catalog (~170 entries
across 16 categories)
- §6 runtime row-pinpoint enrichment with
schema-resolved facts
- §9 migration sweep — every user-visible literal in
src/ now flows through the catalog (caught a ui.rs
gap during the post-sweep manual sanity check, folded
it in as sweep 3/3)
## Recommended next move
Parser-as-source-of-truth ADR + H1a implementation. The
friendly-error layer made engine errors much better;
parse-error wording is now the visibly-weakest user
surface. User explicitly surfaced the gap during manual
testing this session ("typing `create` should illustrate
the expectation"). Bounded scope, high pedagogical value,
unblocks I3/I4 in passing.
A1 (CI workflow) noted as the easy alternative for a
quick win first.
## Sharp edges captured
- New i18n workflow: catalog + keys.rs + t!() at every
use site, validator catches drift
- TranslateContext is owned (no lifetime); App combines
runtime FailureContext with verbosity
- Anchor phrases load-bearing per ADR-0019 §10
- `running: ` prefix coupled to caret-padding math
- main.rs initialises catalog before args parsing
- Several alignment-coupled strings deliberately left out
of the catalog (echo prefix tags, mode labels)

ADR-0019 §9 sweep (3/3): ui.rs prose strings (caught in manual sanity)
Surprise gap from the post-sweep sanity check — `ui.rs` had a substantial set of TUI-rendered strings that the previous two sweep passes didn't cover. Caught by grepping for capitalised literals in `ui.rs` after running the binary smoke check. ## Migrated - **modal.*** — load picker title / empty state / path prompt; rebuild confirm title / "Continue?" prompt. (modal.path_entry's title comes from `save.*` since it's the save / save-as dialog.) - **save.*** — `save` no-op hint, modal titles for Save / Save as, modal prompt body. - **status.*** — status bar `Project:` label and the `(no project)` placeholder. - **panel.*** — `Tables` panel title, `(none yet)` placeholder for empty tables, `(no active hint)` placeholder for the hint panel. - **shortcut.*** — the bottom-bar keyboard hint labels (submit, confirm, cancel, yes, no, load, select, browse_path, back_to_list, switch, advanced_once, cancel_one_shot, quit). Each is a translatable label paired with a key name (Enter / Esc / Ctrl-C / etc.) at the call site. Keystroke names are deliberately left as literals — translating them would mean retraining users away from what their keyboard says. The `push_shortcut` closure's parameter type changed from `&'static str` to `&str` so it accepts the catalog-returned String. ## Deliberately left - **Echo prefix tags**: `[simple] `, `[advanced] `, `[system] `, `[error] `. Their column widths are hardcoded into the wrap-width calculation in `render_output_panel`; translating them would silently break alignment. Worth a follow-up pass if a future locale needs different prefixes (would need `mode.label()` and the echo-tag widths to live behind a single locale-aware function). - **Mode labels**: `SIMPLE` / `ADVANCED` / `Advanced:` rendered in the input panel border. Same alignment reasoning as the echo tags — also they're keywords (the user types `mode simple` to switch), so translating the display label without translating the command word would be confusing. Left as is. - **Visual decoration**: `[Y]`, `[N]`, `[TEMP] `, `>` cursor markers, `█` cursor block, `↑↓` arrow glyph, `›` selection marker. Universal symbols / labels rather than translatable prose. ## Catalog totals The catalog now has ~170 entries across 16 categories. `tests/engine_vocabulary_audit` passes — no engine vocabulary leaks anywhere user-reachable. ## Tally 610 tests passing (no change — pure refactor with identical-output catalog substitutions). Clippy clean with nursery lints. Release builds at 7.8 MB. ADR-0019 §9 is now genuinely complete. |

ADR-0019 §9 sweep (2/2): help blocks + modals + system notes
Final pass of the i18n migration sweep. Every user-visible
string in `src/` now flows through the catalog via `t!()`.
## Categories migrated in this commit
- **help.cli_banner** — the entire `cli::HELP_TEXT` const,
formerly a 40-line `&'static str`, is now a YAML block in
the catalog. The const is replaced by a thin
`cli::help_text() -> String` wrapper that performs the
catalog lookup. `main.rs` calls `help_text()` for both
`--help` output and the args-parse error path. The two
integration tests that referenced `HELP_TEXT` directly are
updated.
- **help.in_app_body** — the in-app `help` command's body is
one YAML block; `note_help` becomes 5 lines that iterate
the lines and emit each as its own output row (preserving
the renderer's "one logical line = one display row"
invariant for accurate scroll math).
- **modal.*** — load picker, rebuild confirm, and save-as
path-entry strings: rebuild_cancelled, load_cancelled,
generic_cancelled, load_picker_nothing,
path_entry_empty_name, path_entry_empty_path.
- **dsl.failed** — the `"<verb> <subject>" failed: <rendered>`
wrapper around the friendly-error layer's translated
message.
- **dsl.running** — the `running: <input>` echo line shown
above each command's response. (Note: the en-US prefix
"running: " is hardcoded in the parse-error caret-padding
calculation. Translators changing the prefix must keep the
width consistent — documented inline.)
- **advanced_mode.not_implemented** — the placeholder echo
shown when SQL hits the unimplemented advanced-mode path
(Q1 territory).
- **fatal.persistence** — the FATAL banner for
PersistenceFatal events (ADR-0015 §8).
- **project.{load_path_missing,saveas_target_exists,**
**import_zip_missing}** — runtime-side project-switch
validation errors that surface via ProjectSwitchFailed.
## Catalog start-up ordering
`main.rs` now calls `friendly::catalog()` at the very top
(before args parsing) so `help_text()` works in both the
success path and the args-error path. A corrupted build
artefact still fails loudly with a useful panic; the
practical risk is essentially zero since the catalog is
`include_str!`'d at compile time and validated by the unit
test before shipping.
## Remaining literals
The only `note_*` calls in `src/` that still pass plain
strings are inside `#[cfg(test)]` modules — synthetic test
fixtures, not user-visible. The codebase passes the "every
user-visible string flows through the catalog" bar.
## Tally
610 tests passing (no change in count — pure refactor).
Clippy clean with nursery lints.
## What this closes
ADR-0019 §9 (migration sweep) — done.
ADR-0019 itself is now fully implemented:
- §1-§5: catalog + translator + voice + verbosity ✓ (`eac7e5b`)
- §6: row pinpointing + schema enrichment ✓ (`431645a`)
- §9: migration sweep ✓ (this + `aff528a`)
- §10: anchor phrases preserved throughout ✓
- The five "Out of scope" items remain explicitly bounded
to future ADRs (advanced-mode SQL, settings persistence,
pluralisation, runtime locale, value formatting,
constraint management).

ADR-0019 §9 sweep (1/2): replay/client_side/ok/mode/messages/project/parse
First half of the catalog migration sweep. Six categories of
user-visible literals moved from inline `format!` calls to the
i18n catalog via `t!()`:
- **replay.*** — `[ok] replay … N command(s) run`,
`replay … failed at line N: …`, the `> command` echo, and
the inner `could not open` / `parse error` / `nested replay`
wordings the runtime constructs inside `ReplayFailed.error`.
- **client_side.*** — the four [client-side] pedagogical notes
from ADR-0017 §6 / ADR-0018 §9 (transformed,
transformed_lossy, auto_fill_transition,
auto_fill_add_serial, auto_fill_add_shortid). The
`format_auto_fill_add_note` helper in db.rs now routes via
the catalog too.
- **ok.*** — the `[ok] {verb} {subject}` summary header
(consolidated through a new `App::note_ok_summary` helper)
plus the per-operation row-count footers
(`{count} row(s) inserted/updated/deleted`).
- **mode.*** — `mode: simple/advanced` set/show banners +
`usage: mode …` + `unknown mode '{value}' …` errors.
- **messages.*** — `messages: short/verbose` set/show + the
`unknown messages mode` error.
- **project.*** — `[ok] rebuild — {summary}`, `[ok] now
editing: {display_name}`, `[ok] export — wrote {path}`, plus
matching failure variants and the `usage: export/import`
+ `import: empty target after as` argument-parsing errors.
- **parse.*** — the `parse error: {detail}` wrapper around
chumsky's structural output, the `{padding}^` caret pointer,
and the `empty input` fallback for `ParseError::Empty`.
Catalog total: 99 lines of YAML across the new categories,
44 new entries declared in `keys.rs::KEYS_AND_PLACEHOLDERS`.
The validator (`keys_validate_against_catalog`) walks the
expanded list and confirms placeholder coverage / no format
specifiers / no engine vocabulary across every entry.
Anchor phrases (ADR-0019 §10) preserved verbatim; existing
substring assertions in the test suite hold.
## Tally
610 tests passing (no change in count — pure refactor).
Clippy clean with nursery lints. Release builds.
## Still ahead in the sweep
- Sweep 7: HELP_TEXT (CLI banner) + in-app `note_help` —
large multi-line blocks.
- Sweep 8: modal labels (load picker, rebuild confirm,
save-as path entry) + any remaining strays. Final pass.
Both shipping in a follow-up commit so this checkpoint
stays reviewable.

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-0019: pluralisation is a translator concern, not deferred work
Per follow-up review: §8.5's framing read as "we'll do this properly later". Reword to make it explicit that real plural-form rules per locale (Fluent / ICU) are NOT a goal of this project. Translators handle pluralisation in their wording (`(s)` shorthand or rephrased templates) — sufficient for a teaching tool's output surface, and we're not planning to revisit it. Matching Out-of-Scope entry tightened the same way. |

ADR-0019: friendly error layer (H1) and i18n message catalog
Settles the design we discussed across this session's
follow-up to the engine-vocabulary audit:
- A central `friendly` module owns translation; the existing
ad-hoc helpers (`friendly_change_column_engine_error`,
`enrich_fk_message`) absorb into it.
- Initial catalog covers UNIQUE / FK / NOT NULL / CHECK /
type-mismatch errors with operation-tailored,
pedagogically-voiced wording in verbose and short variants.
- New `messages (short|verbose)` app-level command lets
advanced learners shrink the output. In-session state for
now; persisted later when settings persistence lands.
- Row pinpointing via post-failure re-query, rendered through
ADR-0017 §7's bordered diagnostic-table renderer.
`FriendlyError` is a structured payload (headline + hint +
optional table); `output_render` composes it.
- i18n foundation: hierarchical YAML catalog, embedded via
`include_str!`, fixed locale (en-US) for now, no external
files. `{name}` plain substitution; format specifiers
explicitly rejected so a translator cannot reformat values.
Value formats stay invariant across all locales (ISO 8601
dates, `.` decimals, `true`/`false`, `NULL`) — explicitly
not a translatable concern.
- Migration sweep is required follow-on but separable: a
`t!()` macro marks call sites and lets per-category PRs
land incrementally. Anchor-phrase list (§10) limits test
churn for the most common substring assertions.
Out of scope and explicitly deferred: advanced-mode SQL
error sanitisation (waits on Q1), settings persistence for
the messages command, plural-form rules per locale, runtime
locale selection, locale-aware value formatting (rejected,
not deferred), constraint-management surface (C3 territory).
