Soul's pass found the suite claimed more than it proved: H1-H20 killed
twenty mutations, and nineteen further permissivenesses could be restored
with every test still green. A rule no test reaches is a rule the next
pass may delete by accident.
Two of them were about the receipt's atomicity and its reach, and needed
new machinery. A store in `receipt.rs`'s tests records the replacement set
of every swap it is asked for, which lets one test say what no assertion
over the resulting image could: a commit is one compare-and-swap, and the
documents and their receipt go in it together. Splitting the receipt into
a second swap now fails. Separately, a batch citing three image documents
is pinned against all three, so truncating the strong reads to the first
of them fails.
The rest are one fixture apiece, each closing a row the per-kind rules
already held: stewardship looked up in image as well as batch; the cut
report's repo as well as its branch; a promise measured by the claim that
names that label; the invariant vocabulary taken from the in-force target
and not a superseded one; a question that is answered or withdrawn but
never superseded, and a target never answered; the derived stewardship
dated by the hand-off; derived writes passing A3-A7, so a derived identity
the batch already holds is A4's refusal and not a store error; A4 and A2
themselves; a question's two distinct options and its recommendation among
them; unique labels on a question's options and a target's invariants; a
finding's locations; and an `Answered` naming the ruling that actually
answers its subject.
`tools/eureka-cut8-mutations.psd1` grows to H1-H39. H21 and H22 pin the
opener's epoch key and count, H23 `EmptyRepos`; the rest are Soul's own
survivors, adopted as entries so the thing that found them is the thing
that guards them.
Harness: M0 green at 31 tests, H1-H39 all killed by their own test.
