The infrastructure/events/bus.py module had 0 tests when the issue was filed. A prior PR added the base test suite; this PR extends it to cover the remaining uncovered paths.

Changes

Added TestSingletonHelpers class with 5 tests:
- get_event_bus() singleton identity
- init_event_bus_persistence() sets path on singleton
- init_event_bus_persistence() is idempotent (second call ignored)
- init_event_bus_persistence() uses data/events.db as default path
- Module __getattr__ raises AttributeError for unknown attributes
Added 2 persistence error-handling tests:
- _persist_event() swallows sqlite3.OperationalError (lines 143-144)
- replay() returns [] on query failure (lines 200-202)

Coverage

infrastructure/events/bus.py: 92.7% → 99.3% (38 tests, all passing)

The single remaining uncovered line (101) is a defensive early-return guard inside _init_persistence_db that is structurally unreachable through the public API.

Add tests for previously uncovered code paths in infrastructure.events.bus:
- TestSingletonHelpers: get_event_bus() singleton, init_event_bus_persistence()
  (idempotency and default-path behaviour), and module __getattr__ error path
- TestEventBusPersistence: exception-swallowing in _persist_event() and replay()
  (lines 143-144 and 200-202) via patched contextmanager

Coverage: 92.7% → 99.3% (38 tests, all passing).
