A prose-form routing target blocks a commit only when its own sentence names another target that resolves. That makes the sentence splitter part of the ADR-0020 contract rather than an implementation detail, and the naive "period, space, capital" rule got it wrong in both directions: - OVER-SPLIT: `e.g. "..."` is not a sentence end, but the quote looks like a start. The clause was cut in half and the corroborator stranded on the far side, so a genuinely dangling target silently demoted to SUGGESTION — a measurement taken and then discarded, the vacuous-green shape this gate exists to prevent. Seven such splits are live in the current corpus. - UNDER-SPLIT: a sentence opening with a code span or a lowercase skill name was not seen as a start, so two sentences merged and a resolving target vouched for an unresolvable one it never stood beside — a hard FAIL with no escape hatch, which is the exact failure corroboration was added to prevent. The splitter now excludes the five abbreviations that occur in routing prose and admits a backtick or lowercase letter as a sentence opener. Applied byte-identically to all three copies of the shared resolver. Verified zero-delta against the corpus: 37 ERROR / 58 SUGGESTION / 2 dangling before and after, findings byte-identical. The exposure this closes is to the descriptions #99 is about to rewrite, not to the ones already measured — which is why the deferral reason recorded on PR #103 ("can move the documented corpus counts") does not hold and the fix lands here rather than after the retrofit. Three regression tests, one per direction plus the backtick opener, each proven non-vacuous by reverting the splitter alone and watching it go red.
