Subject: [PATCH] observations_gate: normalise emphasis before matching a
 marker (R-419 follow-up)

My first fix was too strict. It anchored a marker to a line start or a bare '. ', which misses the
commonest real shape - a bolded sentence followed by a bolded marker: '...them.** **FILED: R-427**'.

CAUGHT BY THE GATE CONVICTING THE VERY REPORT THAT DOCUMENTS IT, on two of its own observations.
That is the both-directions check working: a gate that rejects the decoy AND the genuine article is
worse than the hole it replaced.

Code spans are stripped FIRST and that order matters - a marker inside backticks is being talked
about, never used, and removing it is what makes the R-419 decoy fail. Emphasis is stripped second so
'**FILED: R-1**' and 'FILED: R-1' are the same thing to the anchor.

Decoy suite re-run: the R-419 decoy and a backticked-only mention are still REFUSED; both genuine
marker shapes pass.
