checks / unit (pull_request) Successful in 6m55s
Review approved and then attacked part 5b, the control that stands between B1's
defect and a green suite. It got through in three edits:
A1 delete `END LEG` 5b CATCHES it 2 FAIL
A2 ...and reorder the legs 5b BLIND 1 FAIL
A3 ...and reword the closing summary 0 FAIL, "all checks passed"
with a splitter that closed
ZERO legs
⚠️ TWO OF THOSE THREE ARE ORDINARY REFACTORS - reordering report legs, rewording
a summary line - and neither reads as touching a safety check. 5b caught the
unclosed splitter only because the clean leg happened to be printed LAST, and
the backstop that saved A2 was a hardcoded transcription of the tool's own
sentence, so rewording that sentence blinded it too.
FIXED BY ASSERTING THE STRUCTURE RATHER THAN ADDING A FIXTURE: a leg may not
open while one is open, and every leg that opens must be explicitly closed.
Driven - deleting `END LEG` now fails on the FIRST edit, whatever the order or
the wording:
AssertionError: leg 'SAME-STEP' opened while 'STAGED' was still open - the
tool stopped closing its legs, and a splitter that never closes swallows the
closing summary into the last leg.
All three attacks include that edit, so one assertion kills the class. Clean
tree unchanged: 28/28, all checks passed.
⭐ AND THE RULE IN MUTATION.md IS EXTENDED, because review's finding is the
general case of it. It said "a per-thing check that has never seen the things
DISAGREE is a total". Part 5b DOES make them disagree, every run, and was still
blind. So:
...AND ONE THAT HAS ONLY SEEN THEM DISAGREE IN ONE ARRANGEMENT IS A TOTAL
OVER THAT ARRANGEMENT. When a fixture cannot enumerate the arrangements,
assert the invariant they share.
Also recorded, NOT fixed, with the reason: the reference carries `entity_id
unique_id device` and grades all three, but never the discovery TOPIC. Review
measured `homeassistant/... -> ha/...` exiting 0 with no findings while every
announced entity dies. `discovery_payloads()` already returns the topic and
`announced_rows` discards it, so a fourth column closes it - but the prefix is
HA's fixed contract rather than a name this project chooses, so it is not what a
tidy-up rename reaches. Lower LIKELIHOOD than the N1 gap it resembles, not lower
consequence, and it stops being a note the day the topic becomes configurable.
Two stale figures corrected: the tool claimed five migration mutations where
there are nine, and pointed at a DOCS.md heading that does not exist (the real
one is "Before you commission inverter B", verified present at DOCS.md:1577).
