  "message": "Remove `{bb,next}_locs` params to `Tracker::ambiguity()`\n\n`CollectTrackerAndEmitter` can compute this data from\n`Tracker::matched_one()`. The collected data coalesces non-terminal\n`MatcherLoc`s with others, so `partition()` is used to separate them.\nThe data is retrieved from a `HashSet`, but because the results are\nsorted, everything is deterministic.\n\nThis removes some pressure on `TtParser` to use breadth-first traversal.\n\n`tests/ui/macros` pass.\n",
