Six sites re-asserted the predicate waitUntilRuntimeSettles already checks,
with no suspension point in between, so they could never fail; their intent
messages are folded into comments where one was not already stated.
Two commit-failure cases asserted the fake's bookkeeping (updateCalls stays
empty) which the fake guarantees by throwing before recording; the outcome
and committed-snapshot assertions already prove the real behavior.
Also drop a no-op loop that mutated a discarded struct copy, a duplicated
isWellFormed line, two WorkspaceRoute cases subsumed by the constructor and
the publish-count case, a duplicated presentation-message assertion, and the
round-trip halves of two payload-shape cases already covered case-by-case.
