Redesign integration test architecture to eliminate async/sync deadlock:
- Run SimulationServer in dedicated background thread with own event loop
- Rewrite TempCo tests as fully synchronous (no @pytest.mark.asyncio)
- Add ServerThread fixture in tests/integration/conftest.py
- Fix Unicode encoding errors (replace deg, mu, +/- with ASCII)
- Optimize temperature points for faster settling (23C, 25C, 27C)
All 3 TempCo integration tests now passing in ~5 minutes total.

Move synchronous test execution to thread pool executor to avoid
blocking the async event loop. This prevents deadlocks when sync
client code tries to communicate with async server in same loop.
Note: Integration tests still experiencing timeouts - needs further
investigation. Unit tests and TCP server communication are working.
- Fix import sorting in test_instruments.py (ruff I001)
- Install pandas-stubs for mypy type checking
- Add garbage collection cleanup to repository test fixtures
- Prevent Windows file locking errors in tempfile cleanup
All CI checks now passing: lint, type check, and all 244 tests.
- Use X | None syntax instead of Optional[X] (UP045)
- Sort imports in dashboard app (I001)
- Remove unnecessary UTF-8 encoding argument (UP012)
- Add 'from err' to exception re-raises (B904)
- Remove unused imports in integration tests (F401)
- Fix useless expression in test (B018)
- Cast **1.5 result to float in LDO model (mypy no-any-return)
- Use functools.partial instead of lambda in server (mypy misc)
InstrumentServer is a general-purpose SCPI-over-TCP server that can
host any device implementing the SCPIDevice protocol (process method).
Moving it from simulation/ to instruments/transport/ reflects this:
- simulation package now depends on instruments package
- InstrumentServer can host both virtual and real instrument adapters
- Added SCPIDevice Protocol for type-safe device registration
Test connection handling, multiple clients, instrument access across
all three virtual instruments, physics engine integration, and error
handling. Update pytest-asyncio config for v1.x compatibility.
Comprehensive test coverage for MultimeterSim including MEAS:VOLT:DC,
MEAS:CURR:DC, CONF, and READ commands. Tests both standalone operation
and physics engine integration including temperature-dependent measurements.
Comprehensive test coverage for PowerSupplySim including VOLT, CURR,
OUTP, and MEAS commands. Tests both standalone operation and physics
engine integration.
Comprehensive test suite for SCPI command parsing:
- SCPICommand dataclass tests (creation, keyword property)
- Parser tests for queries, commands, arguments
- IEEE 488.2 common command tests (*IDN?, *RST, etc.)
- Edge cases (whitespace, empty strings)
- Instrument-specific command tests
Also fixed bug where is_query was determined from command string
ending rather than header ending (handles queries with arguments).
