Round 5. Two of the eight findings are the em-dash mid-rune slice, which
the orientation matrix had already caught and fixed in 285789c before
this round returned — the harness doing the reviewers' job, which is the
point of it.
Of the rest:
**A marker phrase can open a sentence and still be prose** (kimi).
"That's the chain above. In short supply of alternatives, we went with
B." opens a sentence with "In short" and announces nothing. The marker
must now be followed by the delimiter a model puts after a real
announcement — the colon in "Short version:", the comma in "In short,".
No delimiter means no match, which keeps the terminal: fails closed.
Adding that made the sentence-opening anchor look redundant — a
break-check that removed it survived, because every mid-sentence case in
the table was by then rejected for want of a delimiter. It is not
redundant: "…, and in short, we went with B" is a clause continuation
with a comma. The missing thing was a case for what the anchor alone
does, not the anchor.
**backRefHeadChars was named for the wrong family** (opus; sonnet raised
the same constant from the other side). It is applied only to the
deictic offset test, never to backRefRe. Renamed abovePointerHeadChars.
It stays defined as `= weakFinalMaxChars` rather than inlined, because an
earlier round asked for exactly that linkage and the reason still holds.
**The clause-boundary comment narrated my review history** (opus) — the
same class of finding I took two rounds ago and then reintroduced one
comment over. Rewritten as behaviour, pointing at the matrix.
**analysis1611 was a function returning a constant string** (sonnet) —
now a var.
Accepted, not fixed: a comparative "above," plus a sentence-opening
marker can still reach isSummaryCloser. That needs the comparative false
positive, a real marker, a terminal under 300 bytes, and a same-turn
prior at least 3x longer, all at once; the dwarf ratio is the backstop
and no lexical test separates the comparative from the deictic.
Break-check: seventeen mutations, each killed by a named test.
