test(int): Add Stable Integration Tests Over the Radio

[Mikefly123]

Summary

Adds a second CI integration pass that communicates with the flight software over LoRa RF instead of the direct USB UART, validating that the radio link is functional end-to-end. Introduces the rf_unsafe pytest marker to gate tests that would sever the RF link, and makes numerous improvements to radio test reliability.

A bit of a journey to get here, but very cool now that we can implicitly validate that the radio works along with all of the other functions of the satellite. It does increase the time it takes for integration tests to run from around 10 minutes to 25-30 minutes though, so setting up a second CI runner that can allow for parallel runs would be really beneficial!

Changes

• RF Integration CI Pass
• Added integration-radio CI job that runs the full test suite via the v5d LoRa passthrough TTY (LORA_PASSTHROUGH_TTY)
  integration-uart job now runs before integration-radio; added integration fan-in job to satisfy branch protection check
• CI bootstraps the sequence number over UART before starting the LoRa GDS to ensure command sequencing is correct
• CI restores clean hardware state after RF tests via Korad power-cycle and UART GDS restart
• Merged main's YAMCS round-trip CI test into the integration-uart job
• rf_unsafe Marker
• Added rf_unsafe pytest marker (defined in pytest.ini) to exclude tests that sever the RF link from the radio integration pass
• Marked tests as rf_unsafe: burnwire, antenna deployer, RTC alarm tests, reset manager, raw-bytes smoke test,test_00_setup_only transmit teardown
• test-integration-radio Makefile target filters with not flaky and not rf_unsafe
• test-integration (UART) filter reverted to not flaky only

Radio Test Reliability Improvements

• Stabilization wait: 15-second wait after first TRANSMIT ENABLED + clear_histories() to drain boot-time event backlog before tests begin
• Fibonacci backoff with jitter: Retry delays follow the Fibonacci sequence (1, 1, 2, 3, 5, 8, 13 s) with ±50% random jitter to reduce half-duplex timing collisions
• Radio recovery: Automatically re-sends TRANSMIT ENABLED after 3 consecutive command failures to recover from dropped radio state
• RTC tests moved last: pytest_collection_modifyitems hook in conftest.py moves rtc_test.py to end of collection when --with-radio is active
• TMP112 retry loop: Outer retry loop wraps the full GetTemperature command + Temperature event assertion with 5 s event timeout
• Fail-fast: --exitfirst added to test-integration-radio so the run aborts on the first failure
• Command retries: --with-radio flag bumps retries to 5 per command via proves_send_and_assert_command

Test File Cleanup

• Removed numeric prefixes: 0_radio_test.py and 1_lora_passthrough_test.py deleted; canonical names are radio_test.py and lora_passthrough_test.py
• Removed RADIO_DEBUG_PLAN.md
• Removed requires_hw_watchdog marker from watchdog_test.py
• Removed pytestmark skip from drv2605_test.py

Telemetry & Observability

• Added telemetry sampler fixture and CI artifact upload for integration test runs

@copilot after our recent changes, the last IMU Manager test is consistently flaking now. Interestingly, it is now the only test file that has three tests in sequence with each other, previously (befo...

Done in commit 47efa31.

Added RADIO_RECOVER_THRESHOLD = 3 and _radio_recover_fn to common.py. proves_send_and_assert_command now calls the recovery function every RADIO_RECOVER_THRESHOLD consecutive failures — i.e., after attempts 0, 1, 2 all fail, it re-sends TRANSMIT ENABLED (fire-and-forget) before attempting retry 3. The Fibonacci backoff sleep that follows gives the radio time to settle before the next command attempt.

In conftest.py, start_radio now registers lambda: _enable_radio(fprime_test_api) as the recovery callback via set_radio_recover_fn. The lambda is bound to each test's function-scoped API so the right connection is used if recovery fires mid-test.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• astral.sh
  • Triggering command: /usr/bin/curl curl -LsSf REDACTED (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

@copilot Just two more things to clean up! Address the lint failure by adding the required docstrings to appease Interrogate. Also look into why there is still a pending "integration" check when no actions are scheduled to run for it

Fixed in commits b9de4fd (lint) and 260e986 (CI):

• Lint: ruff format reformatted a long if condition in common.py — the issue was style, not missing docstrings (interrogate actually passed).
• Pending integration check: The old main branch had a job named integration; after the merge it was split into integration-uart / integration-radio, but the branch protection rule still requires a check named integration. Added a lightweight integration fan-in job that depends on both jobs and passes when they both succeed (or are skipped/cancelled), satisfying the branch protection gate.

Great Documentation, especially of issues and stuff, and seems to be passing well!

LGTM!
