Two analyst-UX papercuts surfaced by the v0.53.4 onboarding smoke test.
1) /api/query remote_estimate_failed hint now branches on the BigQuery
error class instead of always claiming a column doesn't exist. The
previous hardcoded "Most often this means a column referenced …
doesn't exist" misled analysts whenever BigQuery actually rejected
on syntax — concretely, `SELECT COUNT(*) AS rows FROM …` fails with
`Syntax error: Unexpected keyword ROWS at [1:20]` (`rows` is a BQ
reserved word) and the hint pointed at non-existent columns.
New _hint_for_bq_bad_request() helper dispatches:
- "Syntax error" / "Unexpected keyword" → reserved-keyword alias hint
with `AS row_count` workaround
- "Unrecognized name" / "not found inside" → `agnes schema <id>`
- "Table not found" → `agnes catalog`
- fallback → enumerate all three
4 unit tests in TestHintForBqBadRequest pin each branch. Existing
guardrail tests (test_fallback_fails_fast_on_pure_duckdb_syntax,
test_remote_estimate_failed_surfaces_first_error_when_attempts_differ)
continue to pass — both hint substrings they assert on still appear in
the relevant branches.
2) `agnes catalog` replaces the FLAVOR column with ENTITY. FLAVOR
rendered t['sql_flavor'] which duplicated SOURCE for any catalog
dominated by one source type — analysts saw `SOURCE=bigquery
FLAVOR=bigquery` on every row. ENTITY instead surfaces the upstream
BigQuery entity_type (BASE TABLE / VIEW / MATERIALIZED_VIEW) for
remote rows; non-remote rows render `-`. The distinction matters
operationally: views don't support predicate pushdown, so `agnes
query --remote` against a view trips the cost guardrail where the
same query against a BASE TABLE pushes down cleanly. The
entity_type field has been in the v2 catalog response since 0.51.0;
this PR just stops hiding it behind a column header that conveyed
no information.
JSON output (`agnes catalog --json`) is unchanged — only the human-
readable column changed. No DB migration; no API change.
Verified: 4161 tests pass locally; 25 in test_api_query_guardrail.py
green; the 4 new TestHintForBqBadRequest cases pin each branch.
