Live-run findings from a real fact-checking task (ankylosing spondylitis
genetics, 7 authoritative sources) against the new mode:
- Verbatim check rejected a legitimate quote because web_extract returns
markdown: the MedlinePlus sentence is "including _[ERAP1](https://...)_,
_[IL1A](...)_" on the wire but plain prose to a reader. The agent was
forced onto a weaker evidence fragment — the opposite of the point.
Matching now canonicalizes inline links to their label and drops
emphasis/code markers and backslash escapes on both sides, so quoting
the sentence a reader sees works. Paraphrases are still rejected.
- Escaped asterisks (HLA-B\*27) no longer have to be reproduced in the
quote, so extractor artifacts stop leaking into rendered evidence.
- New `render --replace-in <draft>`: rewrites a draft's Sources block in
place, idempotently. Previously the only path was hand-slicing the
file, which also tripped over the emitted heading being `## Sources`
while the prose said "Sources:".
- verify stats: report the provenance total that the percentage is
actually computed from (cited + [unverified], counted once), and print
the line as `info:` instead of `warn:` when nothing is wrong. The old
line printed 17 cited / 2 unverified next to 72%, which does not
reconcile — a sentence can be both.
- SKILL.md documents the emitted heading, --replace-in, and exactly what
counts as a prose sentence for --min-coverage.
7 new tests (47 total) using the real MedlinePlus/Frontiers markup;
6 sabotage runs, all red.
