hil: give the board verdict through BoardTask's collector by hathach · Pull Request #649 · adafruit/tinyuf2

hathach · 2026-11-12T07:20:40Z

Problem

The runner gives its board task a verdict by hand from the battery's last action, and assembles the report's lock
object from the task's fields. agentrc hathach/agentrc#543 moves that into BoardTask: a verdict collector run once
at the task's end, and report() for the lock's end. Two cases ended wrong on the way:

a cleanup that raised after the battery touched the board left no cleanup row, which the verdict read as
untouched and ended clean;
a passing restore was published as the row's cleanup before its children were proven ended.

Solution

Verdict collector. board_task(..., verdict=lambda task, exc: end_board(task, row)): end_board gives the one
verdict from the row's cleanup. A touched board whose cleanup did not finish ends failed, logged unrecheckable.
Lock report. row['lock'] is task.report(), which adds ended. An interrupt calls task.finish(e).
Done marker. Written at the end of run_task, when the verdict is not a blocker.
Restore. The cleanup is published only after the restore's children settled.
Pin. test/hil/agentrc.json pins hathach/agentrc@3304c248, lpc55: USB1 high speed on LPCXpresso55S69/55S28, build with CMake, fix UF2 copy on rev 0A #543's merge commit.

Hardware

ci.lan, before the rebase onto #639, with agentrc e1f2f9ef (#543's head before its review fixes: the -pwr ST-LINK
exclusion and an unlogged failure's evidence, neither on these paths):

stm32f407disco, lpcxpresso55s69, stm32h743nucleo: exit 0, 5/5 each, cleanup blinky copied, endedCleanly.
--fail-at cleanup: exit 4, failure logged; a restore under a hold resolved it.
SIGINT on lpcxpresso55s69 at the copy step: exit 1, cleanup passed, released, nothing logged.

pre-commit script tests: 789 passed.

Walkthrough

The HIL runner validates the task-lock helper interface and derives task verdicts from cleanup state. It updates lock reporting, interruption handling, done-marker timing, and restore-result recording. Tests and contract documentation describe helper compatibility and cleanup exception outcomes.

Changes: HIL task lifecycle

Layer / File(s)	Summary
Task-lock helper contract `.claude/skills/hil-contract/scripts/hil_test.py`, `.claude/test/test_hil.py`, `test/hil/agentrc.json`	`load_helper()` requires `board_task` to accept `verdict` and the helper to provide callable `finish()` and `report()` methods. Tests cover incompatible helpers. The configured agentrc commit changes.
Task verdict and cleanup outcomes `.claude/skills/hil-contract/scripts/hil_test.py`, `.claude/test/test_hil.py`, `.claude/skills/hil-contract/SKILL.md`	`run_board` registers `end_board` as the verdict collector and reads lock details from `task.report()`. Interrupted lock waits call `task.finish(e)`. `run_task` handles the done marker after cleanup. Cleanup failures after board use are logged as unrecheckable, and restore success is recorded only after child settling completes. Tests and contract documentation describe these outcomes.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Possibly related issues

adafruit/tinyuf2#638: The PR changes task-scoped lock reporting and cleanup verdict handling, but does not complete the migration described in the issue.
adafruit/tinyuf2#585: The PR changes when restore cleanup completion is recorded, but does not add restored-image verification.

Possibly related PRs

adafruit/tinyuf2#648: The PR uses the same board_task contract and agentrc pin; this change updates that pin and adds contract checks.

Suggested reviewers: ladyada-eagleclaw

Merge Risk: Minimal · up to bdcaa

The change moves HIL board verdict and lock reporting into the task collector, and it refuses older helpers that lack the new interface. No outstanding merge-blocking issues were identified.

Full details: Title check

Explanation

The title names the main change: the board verdict is now given through BoardTask's verdict collector, which matches the summary's core change to hil_test.py and the PR description's stated goal of moving verdict collection into BoardTask. It is short, specific, and follows the expected single-sentence form.

Full details: Description check

Explanation

The description states the problem, the solution (verdict collector, lock report via task.report(), done marker, restore ordering, agentrc pin), and hardware test results. These match the raw summary's changes to hil_test.py, the test file, the SKILL.md documentation, and test/hil/agentrc.json.

Confidence Score: 5/5

[Medium impact] The PR appears safe to merge; no actionable new issue was found.

Summary

Moves the board verdict into BoardTask’s collector and uses report() for the lock’s final state.

BoardTask gives each HIL run its verdict from the finished cleanup.
Restore cleanup appears only after its child processes settle.

Without the check, a helper without BoardTask's verdict collector, finish() or report() passed load_helper() and only failed mid-run, after the board was locked and touched. The refusal now comes from load_helper() before the lock or hardware is used.
