fix: read semantic sources safely (#284)
* fix: read semantic sources safely

* test: retarget reindex per-scope error case to a broken manifest

Reading a broken standalone source was made non-fatal in de1f1a8d (it is
surfaced for repair instead of throwing), so the reindex per-scope error
test no longer captured an error. Point it at a corrupt manifest shard,
which is the remaining fatal read failure the per-scope catch must
isolate, and assert the captured error names the offending file.

* fix(sl): decouple semantic-layer file names from warehouse naming rules

The in-file `name:` field is now the sole source identity; the filename is
a derived label that never participates in identity. This removes the
"Unsafe semantic-layer source name" failure class entirely: any warehouse
identifier (Snowflake's uppercase SIGNED_UP, EVENT$LOG, dotted names) can
be read, overlaid, edited, and deleted.

- New `source-files.ts`: one total filename derivation (safe lowercase
  names verbatim; otherwise slug + sha256-hash suffix, immune to
  case-insensitive-filesystem collisions) and one by-name file resolver.
- Reads resolve by name everywhere; the path-from-name fast path and
  `assertSafeSourceName` are gone.
- Writes resolve-then-write: rewrites land on the file that declares the
  name (human renames survive); new sources get a derived filename; a
  derived path occupied by a different source fails instead of clobbering.
- `readSourceFile` returns null for missing files instead of forcing every
  caller to launder IO errors; `deleteSource` distinguishes manifest-backed
  sources from not-found instead of silently succeeding.
- `sl_write_source` accepts verbatim warehouse identifiers (snake_case is
  now a recommendation for new sources) and rejects sourceName/source.name
  mismatches; `sl_edit_source` rejects name-changing edits.
- Ingest projection commits, gate-repair allowlists, and touched-source
  derivation use resolved paths / in-file names instead of interpolating
  `<connId>/<name>.yaml`.
- Collapsed the five parallel path derivations and duplicated path-token
  helpers onto the shared module; dropped dead service methods.

* fix(sl): resolve sources by declared name end-to-end and gate warehouse SQL with the parser-backed validator

- Key broken/renamed semantic-layer files by their recoverable in-file
  name (slSourceNameForFile) so mid-edit sources stay reachable under
  their real identity in reads, listings, and search
- Derive finalization touched sources from composed-source diffs and
  recover deleted files' declared names from the pre-change commit
  instead of parsing hash-derived filenames
- Resolve revert/rollback paths against history (listFilesAtCommit) so
  human-renamed files are restored where they lived at preHead
- Validate ingest sql_execution through the daemon's sqlglot
  validateReadOnly in the connection's dialect, sharing one
  driver-to-dialect map (sql-analysis/dialect.ts) across MCP and ingest
- Harden the local read-only SQL backstop: accept leading comments,
  reject smuggled second statements, and strip trailing
  semicolons/comments before row-limit wrapping

feat(setup): apply per-role LLM model presets, remove --llm-model (#268)
* feat(setup): write per-role llm model presets

* feat(setup): remove llm model setup flag

* chore(setup): update llm preset guidance

* docs(setup): document llm model presets

* chore(release): sync uv.lock to 0.9.0

* fix(cli): make sl query --execute work on secret-backed connections

sl query --execute used a parallel SQL executor (createDefaultLocalQueryExecutor)
that passed connection.url verbatim into pg, so file:/env: secret references
failed with "SASL: SCRAM-SERVER-FIRST-MESSAGE: client password must be a string".

Collapse onto the connector-based executor already used by MCP and ingest
(createKtxCliIngestQueryExecutor), which resolves secret references and supports
every driver. Delete the now-dead local/postgres/sqlite query executors, their
tests, and the orphaned hasLocalQueryExecutor driver flag.

* docs(agents): require one implementation per capability

Add a design-reasoning default and a matching self-check question telling agents
to route callers through a single shared implementation of a capability rather
than forking a parallel one, and to fix the shared layer rather than patch one
branch. Encodes the lesson from a divergent SQL-execution-path bug, stated
generally.

CLAUDE.md is a symlink to AGENTS.md, so both agent-instruction files are covered.

feat(mysql): implement columnStats using INFORMATION_SCHEMA.STATISTICS (#233)
* feat(mysql): implement columnStats using INFORMATION_SCHEMA.STATISTICS

Enable column cardinality statistics for the MySQL connector by querying
INFORMATION_SCHEMA.STATISTICS, which provides index-based cardinality
estimates without requiring additional permissions.

- Add generateColumnStatisticsQuery() to KtxMysqlDialect
- Add getColumnStatistics() and columnStats() to KtxMysqlScanConnector
- Flip columnStats capability from false to true
- Add MysqlStatsRow and KtxMysqlColumnStatisticsResult interfaces
- Add tests for dialect query generation and connector stats retrieval
- Update dialect conformance fixture for mysql

* fix(mysql): filter to leading index columns to avoid inflated cardinality

Add AND SEQ_IN_INDEX = 1 to INFORMATION_SCHEMA.STATISTICS query to
ensure only leading index columns are returned. For composite indexes,
non-leading columns report the cardinality of the index prefix rather
than the column's own distinct count, which inflates distinctCount.

Add regression test asserting SEQ_IN_INDEX = 1 is present in the query.

* fix: add trailing newline to dialect.test.ts

* chore(workspace): enforce dialect import boundary

* refactor(cli): resolve relationship dialect at scan boundary

* refactor(cli): use dialect display parsing for entity details

* refactor(cli): test warehouse connections through driver registry

* fix(cli): close driver registry type export gaps

* Improve setup daemon diagnostics

* refactor(setup): centralize rail-prefixed diagnostics + query-history fallback

Extract errorMessage, writePrefixedLines, and flushPrefixedBufferedCommandOutput
into clack.ts so the setup wizard, managed daemons, and embedding/agent steps
share one rail-formatted writer. setup-databases.ts also adds a
"disable query history and retry" option when the schema-context build fails
and query history is the likely culprit, surfaced via a new
failed-query-history-unavailable status.

* fix(cli): carry catalog through the picker so BigQuery/Snowflake/SQL Server scope filters match

The setup picker's KtxTableListEntry was a 2-level { schema, name }, so
qualifiedTableId always wrote db.name into enabled_tables. When BigQuery,
Snowflake, or SQL Server later ran fast ingest, their introspect step filtered
the scope set with scopedTableNames(scope, { catalog: projectId|database, db })
— catalog was non-null on the introspect side but null in the scope refs, so
every entry was rejected, the live-database adapter staged zero table files,
and detect() failed with 'Adapter "live-database" did not recognize fetched
source output'.

Align the picker boundary with the canonical 3-level KtxTableRef:

- Add catalog: string | null to KtxTableListEntry.
- BigQuery/Snowflake/SQL Server listTables populate catalog from the
  resolved projectId / database; Postgres/MySQL/ClickHouse/SQLite set null.
- qualifiedTableId emits catalog.schema.name when catalog is non-null
  (resolveEnabledTables already accepts the 3-part shape) and
  schemasFromEnabledTables now goes through parseDottedTableEntry so it
  recovers the schema correctly from both 2-part and 3-part entries.
- Export parseDottedTableEntry from enabled-tables.ts (@internal) for picker
  reuse.

Update listTables expectations in all seven connector tests and the setup /
picker test fixtures. Add a picker regression test that covers the
catalog-bearing round-trip (save + refine).
