fix(774): cover the WRITE side too, and name the read-side test what it actually is
Cold review of the rescue returned BLOCKED on two, both fair.

THE SUBSTANTIVE ONE: the deleted parity test checked disjointness on BOTH scripts; the
rescue covered only the read side. Review demonstrated the gap rather than asserting it —
adding `BLOCKED` to post-review-verdict.sh's SUCCESS arm produced an overlap the deleted
test caught and the rescue did not, because the rescue never executes that script. That was
a real, undisclosed loss, and it is the second time in two commits that removing something
dropped an invariant nobody enumerated. So:

  test_post_review_verdict.py::test_each_verdict_word_posts_its_established_polarity

`case` takes the FIRST matching arm, so a token in both arms is not ambiguous — it resolves
to whichever comes first, exactly as `is_pos` wins on the read side. Same consequence, and
it is the one that matters: a word a reviewer means as BLOCKED posting `success` writes a
GREEN `review-verdict/h10`, the required context branch protection honours. Mutation-proved
with the exact case review cited: `BLOCKED` in the success arm -> the test names it and
reddens.

THE NAMING ONE, and it is the mistake I keep repeating: the read-side test called itself a
disjointness test and its docstring said "no word may be in both vocabularies", while it
pins the observable classification of five hardcoded tokens. For a UNIVERSAL property an
omitted token is not a vacuous pass, it is precisely the untested member — the record's own
warning. Renamed to test_each_verdict_word_retains_its_established_polarity and the
docstring now scopes itself to the five words. Both surviving tests are polarity
regressions, not disjointness and not parity.

The inventory now enumerates all seven invariants the withdrawn file asserted and says where
each went — five retired to #788, two rescued as per-script polarity. Enumerating on removal
is `process.enumerate-workaround-behaviors-before-deleting`, which this branch has now
failed twice and should stop failing.

584 script-tests pass, pyright clean, decisions-validate OK. ruff reports one S105 in
test_post_review_verdict.py:103 — PRE-EXISTING and a known false positive on a test stub
(identical on origin/main, my additions start at line 335); it is #780's territory.
(--no-verify: pre-commit hook exceeds the tool timeout; its checks were run explicitly.)
