agessaman ba23899c31 fix(correlation): tie channel messages to their own RF packet
{packet_hash} came back empty on a channel, and so did {path} and
{connection_info}. message.routing_info is only attached when the RF row is
correlated, and a channel message can never correlate: MeshCore's CHAN event
carries neither raw_hex nor a pubkey prefix, so every prefix strategy in
find_recent_rf_data is skipped and the message lands on the most-recent-packet
fallback, which #80 rightly refuses to take a route from.

The fallback is in fact almost always the right packet—the firmware emits the
RF log row and the decoded CHAN event for one reception back to back—but
"almost always" is a guess, and #80 is what guessing costs. The CHAN payload
does restate three things the RF row records independently: payload type,
path length and SNR. Requiring all three to agree, on a row no older than the
correlation window, turns the fallback into a checked hypothesis and earns a
real match kind rather than a fallback tag.

SNR carries the weight: it is one reception's measured value, quantised to
0.25 dB, so an unrelated packet agreeing on all three is improbable rather
than merely unlikely. Across the 55 channel messages in my logs the
immediately preceding RF row agreed on all three every time, always within a
second, while a window-wide search on the same fields was ambiguous for half
of them—so this verifies the ordering the firmware already gives us instead
of searching for a match.

Because these messages now correlate, they also satisfy the '*' gate by the
primary route, resolve their scope properly when flood_scopes is regional,
and contribute their path to the mesh graph, which they never did before.

Writing New Tests

Unit Test Example

import pytest
from tests.helpers import create_test_edge

@pytest.mark.unit
class TestMyFeature:
    def test_my_feature(self, mesh_graph):
        """Test description."""
        mesh_graph.add_edge('01', '7e')
        assert mesh_graph.has_edge('01', '7e')

Integration Test Example

import pytest

@pytest.mark.integration
class TestMyIntegration:
    def test_my_integration(self, mock_bot, test_db):
        """Test description."""
        # Use real database and bot components
        pass

Test Markers

Tests are marked with:

  • @pytest.mark.unit: Unit tests (isolated, with mocks)
  • @pytest.mark.integration: Integration tests (with real database)
  • @pytest.mark.slow: Slow-running tests

Dependencies

Test dependencies are in requirements.txt:

  • pytest>=7.0.0
  • pytest-asyncio>=0.21.0
  • pytest-mock>=3.10.0
  • pytest-cov>=4.0.0

Configuration

Pytest configuration is in pytest.ini:

  • Test discovery patterns
  • Async test support
  • Output options
  • Test markers

Notes

  • Unit tests use in-memory SQLite databases for speed
  • Integration tests may use real database connections
  • All tests should be deterministic and not depend on external services
  • Tests should clean up after themselves (fixtures handle this automatically)
