Issue for this PR

Closes #579

How did you verify your code works?

  • All 24 new driver security tests pass (DuckDB retry, MongoDB blocking, PG/Redshift validation, registry hints)
  • 832/832 simulation suite tests pass
  • 28/28 feature discovery e2e tests pass
  • 125/125 telemetry tests pass

Changes

Code fixes:

  • Remove duplicate altimate_change end markers in prompt.ts (lines 812, 962)
  • Fix classifySkillTrigger() to return "unknown" for unexpected triggers (was dead code)
  • Remove unused "schema_not_indexed" from feature_suggestion telemetry type

Undefined display bugs (7 files):

  • sql-translate.ts: null guards on source_dialect/target_dialect
  • dbt-manifest.ts: null guards on model.name, source.source_name, source.name + propagate result.error to metadata
  • dbt-lineage.ts: null guards on model_name, confidence
  • altimate-core-column-lineage.ts / altimate-core-track-lineage.ts: null guards on edge.source/edge.target

Test credential cleanup:

  • Replace password: "secret""test-fake-password" in 3 test fixtures

New driver security tests (24 tests):

  • DuckDB: wrapDuckDBError wrapping, lock retry with READ_ONLY fallback, in-memory no-retry
  • MongoDB: $out/$merge write stage blocking, $function/$accumulator JS execution blocking, safe pipeline passthrough
  • PostgreSQL: password type validation, statement_timeout with valid/NaN/negative values
  • Redshift: password type validation
  • Registry: ClickHouse/Cassandra/CockroachDB/TimescaleDB friendly hints, unknown type error

Documentation:

  • DuckDB: concurrent access auto-retry note in warehouses.md
  • MongoDB: blocked operators warning in warehouses.md
  • New "Unsupported Databases" section with workaround table

🤖 Generated with Claude Code

Poem

"I'm a rabbit in a data patch, I hop through docs and tests,
I mend the gaps where errors hatch and guard the system's nests.
Locks retried, nulls now tamed, telemetry trimmed just right—
A tiny hop, a joyful twitch, we ship into the night! 🐇✨"

Inconsistent null guards: title uses unguarded values.

The formatDbtLineage function now correctly guards result.model_name and result.confidence with ?? "unknown", but the title at line 25 still interpolates these values directly. If either is undefined, the title will display "undefined".

🧹 Nitpick comments (2)
packages/opencode/src/altimate/tools/dbt-manifest.ts (1)

24-24: Type cast (result as any).error indicates a missing type definition.

The DbtManifestResult interface (in types.ts:197-206) doesn't include an error field, necessitating this cast. Consider updating the interface to include error?: string for type safety.

Additionally, other consumers of Dispatcher.call("dbt.manifest", ...) (e.g., impact-analysis.ts:32-43, project-scan.ts:498-505) don't check for this error field and may silently proceed with partial/invalid data.

🔧 Update the interface to include the error field

In packages/opencode/src/altimate/native/types.ts:

 export interface DbtManifestResult {
   models: DbtModelInfo[]
   sources: DbtSourceInfo[]
   tests: DbtTestInfo[]
   source_count: number
   model_count: number
   test_count: number
   snapshot_count: number
   seed_count: number
+  error?: string
 }

Then in this file, replace the cast:

-          ...((result as any).error && { error: (result as any).error }),
+          ...(result.error && { error: result.error }),

In `@packages/opencode/src/altimate/tools/dbt-manifest.ts` at line 24, Add an
optional error field to the DbtManifestResult interface (e.g., error?: string)
so we don't need to cast (result as any).error; then remove the cast in
dbt-manifest.ts and return the error property directly. Also update callers of
Dispatcher.call("dbt.manifest", ...) such as any usage in impact-analysis and
project-scan to check for result.error before proceeding (handle/throw or bail
out if present) so they don't operate on partial/invalid data.
packages/drivers/test/driver-security.test.ts (1)

14-16: Consider adding mock cleanup for test isolation.

The DuckDB, PostgreSQL, and Redshift test sections use mock.module() inline within each test but don't call mock.restore() in an afterEach hook. While the MongoDB section properly implements cleanup (lines 253-256), the other sections don't follow this pattern.

This could lead to test pollution if Bun's module cache doesn't fully reset between tests or if tests run in parallel in the future.

♻️ Suggested pattern (apply to DuckDB, PostgreSQL, Redshift sections)
 describe("DuckDB driver", () => {
+  afterEach(() => {
+    mock.restore()
+  })
+
   // Test wrapDuckDBError logic inline (it's a closure, so we test via connect behavior)
   describe("wrapDuckDBError", () => {

Similarly for PostgreSQL (after line 370) and Redshift (after line 560).
