test: adversarial telemetry safety tests + defensive helper fixes
14 adversarial tests that mock Telemetry.track to ALWAYS THROW, then verify every driver operation still succeeds: - warehouse.list with throwing census telemetry - warehouse.test with throwing connect telemetry - warehouse.add with throwing telemetry - warehouse.discover with throwing telemetry - 10 sequential operations with throwing telemetry - Telemetry.getContext() throwing - Helper functions with null/undefined/bizarre input Defensive fixes to helper functions: - detectAuthMethod: handles null, undefined, non-object input - detectQueryType: handles null, undefined, non-string input - Both return safe defaults instead of crashing These tests guarantee the previous incident (bad telemetry breaking drivers) cannot happen again.

feat: add warehouse telemetry — connect, query, introspection, discovery, census
2-
3-
Add 5 telemetry event types for data moat insights:
4-
5-
warehouse_connect — every connection attempt:
6-
- warehouse_type, auth_method (password/key_pair/token/file/connection_string)
7-
- success/failure, duration_ms
8-
- error_category (auth_failed/network_error/driver_missing/config_error/timeout)
9-
10-
warehouse_query — every SQL execution:
11-
- warehouse_type, query_type (SELECT/INSERT/UPDATE/DELETE/DDL/SHOW)
12-
- success/failure, duration_ms, row_count, truncated
13-
- error_category (syntax_error/permission_denied/timeout/connection_lost)
14-
15-
warehouse_introspection — schema discovery operations:
16-
- operation (index_warehouse), result_count
17-
18-
warehouse_discovery — auto-discovery runs:
19-
- source (docker/dbt_profiles/env), connections_found, warehouse_types
20-
21-
warehouse_census — one-time per session:
22-
- total_connections, warehouse_types[], connection_sources[]
23-
- has_ssh_tunnel, has_keychain
24-
25-
Safety: every Telemetry.track() wrapped in try/catch — telemetry
26-
failures never break user operations.
27-
28-
Data moat value:
29-
- Popular connectors (warehouse_type frequency)
30-
- Auth method adoption (password vs key-pair vs token)
31-
- Failure patterns (error_category distribution)
32-
- Query patterns (SELECT vs DDL vs DML ratios)
33-
- Schema usage (introspection frequency per warehouse)
34-
- Connection sources (config vs env vs dbt)
35-
36-
41 new tests covering auth detection, error categorization, census
37-
deduplication, query type detection, and safety guarantees.

test: adversarial telemetry safety tests + defensive helper fixes
2+
3+
14 adversarial tests that mock Telemetry.track to ALWAYS THROW,
4+
then verify every driver operation still succeeds:
5+
- warehouse.list with throwing census telemetry
6+
- warehouse.test with throwing connect telemetry
7+
- warehouse.add with throwing telemetry
8+
- warehouse.discover with throwing telemetry
9+
- 10 sequential operations with throwing telemetry
10+
- Telemetry.getContext() throwing
11+
- Helper functions with null/undefined/bizarre input
12+
13+
Defensive fixes to helper functions:
14+
- detectAuthMethod: handles null, undefined, non-object input
15+
- detectQueryType: handles null, undefined, non-string input
16+
- Both return safe defaults instead of crashing
17+
18+
These tests guarantee the previous incident (bad telemetry breaking
19+
drivers) cannot happen again.
