Subject: [PATCH] fix(quality): type the 7 net-new 'as any' casts from #6292
 (Lint red on the release tip)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

#6292 rewrote/added zero-width-marker tests with 7 new 'as any' result casts,
pushing the file past its frozen suppression (84) — and when violations
exceed the suppressed count ESLint reports ALL of them, so the ci.yml Lint
job went red with 90 errors. The 7 new sites get typed shapes (delta /
arguments / choices / output accessors — same pattern as fecf888fd); the
pre-existing debt stays frozen at the exact new count (83). 50/50 tests
green, file lint-clean under the suppressions baseline.
