In `@docs/DATABASE_CONNECTION.md`:
- Around line 19-25: Update the module path in the documentation so it matches
the repository layout: change references to app/database/core.py to
backend/app/database/core.py in the "Engine & Pooling" section (and any other
occurrences), ensuring the doc points to the actual module location used by the
codebase.

43-44: Keep dependency constraints in sync with backend/requirements.txt.
SQLAlchemyis pinned to a specific version in backend/requirements.txt, while pyproject.toml allows a range. If both are used in different environments, this can cause drift. Consider aligning them to a single source of truth.tests/test_agent_state.py (1)
6-25: Consider centralizing sys.path manipulation in a shared test hook.Per-test sys.path edits can be order-dependent. A conftest.py or pytest.ini pythonpath setting would keep test imports consistent and reduce duplication.

59-64: Rename unused async-loop variables to satisfy Ruff B007.Use
_sessionto avoid lint warnings in the async generator loops.Proposed diff
- async for session in mock_db_module.get_db(): + async for _session in mock_db_module.get_db(): # Simulate some work await asyncio.sleep(0.01) return True- async for session in mock_db_module.get_db(): + async for _session in mock_db_module.get_db(): raise ValueError("Simulated Error")Also applies to: 90-91

In `@tests/test_db_pool.py`:
- Around line 59-63: Rename the unused loop variable in the async generators to
silence Ruff B007: in the async def task() where you iterate "async for session
in mock_db_module.get_db():" (and the other occurrence later in the file),
change the loop variable name to "_session" so the variable is clearly marked as
intentionally unused; update both places that consume mock_db_module.get_db() to
use "_session" instead of "session".

In `@tests/test_supabase.py`:
- Line 1: The test import line removed CodeChunk which causes a NameError later;
restore CodeChunk to the import list from backend.app.models.database.supabase
so the file imports "CodeChunk" alongside "User, Interaction, Repository"
(update the statement that currently references User, Interaction, Repository to
include CodeChunk) to match its later usage in tests.
|
Thanks for catching that, CodeChunk is referenced later in the test. |

📝 Description
This PR significantly improves backend reliability by adding comprehensive unit test coverage for core handler, event, and agent state modules. While writing tests, a production bug was discovered and fixed in
HandlerRegistry.get_handler()related to incorrect assumptions about event value types.The changes are intentionally scoped to core backend logic and do not introduce new features or alter public APIs.
🔧 Changes Made
HandlerRegistry.get_handler():event.platformandevent.event_typewere enums with.value🐞 Bug Fix Details
Issue
HandlerRegistry.get_handler()assumedevent.platformandevent.event_typewere enum objects, butBaseEventstores these fields as strings in some cases. This caused handler resolution failures at runtime.Fix
The handler key resolution now gracefully handles both enum and string inputs.
🧪 Verification
All scoped backend tests pass locally:
