P13-S27 round 9: M7's comparator had the wrong artifact and the wrong method
Independent review against 01e76d1. Two findings, both blocking, both in
M7's comparator -- the text round 8 had just rewritten.

Test 10b is not the genuinely validated reference M7 nominated. Its
write-side capability is synthetic_for_fixture(0) and only its reopen uses
the real authority, so M7 would have compared one synthetic fixture against
another with the validated half of the claim absent.

This is a collision between two of the contract's own designs, not a typo.
Round 4 made 10b synthetic-on-write deliberately so M5b's two operands
would be provably independent, and that is exactly what disqualifies it
here. One artifact cannot be both independent of the real authority and
committed under it. Round 8 reused a fixture by name without re-reading
what it had been built to be -- a failure no amount of care about wording
would have caught. M7 now builds its own reference in epiphany-testkit,
committing a base under caps derived from the real constant so pin 3a
validates it on the way in.

The field enumeration could not support its conclusion. It claimed
"everything that could carry provenance" while omitting
FixedHeader.file_uuid -- the field it required to match -- plus the
superblock's generation, manifest_offset, manifest_length and
manifest_hash, and the whole manifest outside canonical_base. Replaced with
whole-image() byte comparison, any difference enumerated and classified
either as justified nondeterminism, normalized with its cause stated, or as
a provenance signal, which is a finding since the refusal may then be
stronger than it needs to be.

That finding retires a technique rather than an instance. A hand-written
list of "every field" is a claim about a struct's contents that is wrong
the moment the struct changes, and this one was wrong the day it was
written. Comparing the whole artifact cannot be incomplete. Same lesson as
tables over numbers, applied to the experiment instead of the prose.

Three further sites caught while amending: section 7 item 6 still said
"M7's three text refusals", surviving round 8's correction of that exact
count in two other places; item 4a's M7 row still named the superseded
method; and round 8's own disposition cell stated it as current. All now
point at M7 rather than restating it.

Still NOT RATIFIED, NOT DISPATCHABLE. Findings 9, 6, 6, 5, 4, 3, 3, 2, 2.
Blocking 4, 4, 4, 4, 2, 3, 3, 2, 2. Nine rounds, none clean. Rounds 8 and 9
both found defects in the preceding round's rewrite of the same paragraph,
so M7 has been wrong in three distinct ways across three consecutive
rounds: unrunnable, wrong artifact, wrong method. The comparator is on its
third design and has never been executed.
