Navigation was built from the review ring while the compare GET also demands containment, so an outside symlink (which stays in the ring) was offered by the strip, the steps, the review's Compare control and the flag landing, and 404ed on arrival. Every one is now built from the compare ring (the review ring filtered by the same conjunction, _in_booth). Two pre-existing gaps compare inherits, fixed at the source: resolve_booth caught only OSError, so a NUL in the booth segment was a 500; record_view opened its marker blocking, so a planted FIFO hung every look. Plus: the page treats %73ide=a as side=a, and the subgrid engine floor is stated. Two findings refuted (a chorded click mid-drag never fires pointerup, measured; booth_items never yields an unquotable rel). r3.toml: 57 rows.

|
|
# holds; the save test (a_save_keeps_the_active_side) sees the pair.
