RED. Measured on R761: 2 763 /Outlines nodes entered the bridge, 2 762 marks
came out, and `unresolved` was 0 -- so one node left no trace in the return
value at all. The lost one is `SVV - Forside`, sharing line 0 with the tree's
own root node `R761 Prosesskoden`. The cause is structural, not an edge value:
the marks are collected in a dict keyed on the destination line index, so a
second bookmark on a line is discarded by `setdefault` in silence. One node
today; a document with several bookmarks per line loses several and reports
none of them.
`outline-collision.pdf` is the fixture no existing one could stand in for --
every other outline fixture puts one bookmark on one line, which is exactly
the case where the defect cannot appear. It is laid out by hand through
`make_fixtures.py` like the other PDF fixtures, and regenerating that file
left every other fixture byte-identical.
The known-negative is in the same commit: `outline-collided.pdf` aside, the
two existing trees must report `collided == 0`, so the counter can be measured
at zero and is not green for an unstated reason.
