Tag the judgement dispatch R7 and record which half of FR-CULL-13 is met

apply_judgement and apply_label carry TRACES: R7, the burst
representative callback FR-CULL-13 with a note that choosing it writes
the grouping and no verdict. The register's status for FR-CULL-13 says
the write-path test is met and the evidence chips are outstanding.

+*Status (2026-09-26).* The write-path half is met; the evidence half is not. `cargo test -p
+traceability` enumerates every write of a rating, flag, colour label or trash membership in the
+shipped code — the catalog setters, any SQL that assigns those columns, the sidecar's judgement
+amendment and the fields that carry one — and holds each to a hand-written list
+(`tools/traceability/src/verdicts.rs`). Each listed write is a key, click or tap (a Slint `on_*`
+callback, checked structurally), a function writing for its caller, whose callers are then checked
+in turn, or a verdict carried from elsewhere: a sidecar or `.xmp` pull, the sync merge of two
+devices' sidecars, the catalog mirrored out to a file, and duplicates consolidation, which moves
+the copies' own verdicts onto the survivor and invents none. A new writer, including one in an
+evidence producer, fails the test until it is listed with a reason; `traces verdicts` prints the
+list. Choosing a burst's representative writes the grouping, not a verdict, and takes a press.
+Outstanding: evidence chips (clipping, focus, burst membership, face counts) on the grid cell and in
+FR-CULL-4's mode, shown as absent rather than zero, and a filter per signal. Eye state alone is
+shown today, on People's face cells and as a library filter.
