Three self-contained blocks of the 386-line method become `_rollout_classify_repeaters` (fills the repeater list and status counts in place), `_rollout_path_traffic_share` (returns the multi-byte, single-byte and total path observations and the percentage) and `_rollout_daily_trend`. Their statements are AST-identical to the originals and run in the same order inside the same connection and try; inputs and outputs were derived from the AST, and nothing else crosses the boundaries.
The nine methods behind the multi-byte rollout page (hop-chunk collection and caching, path encoding badges, single-byte relay metrics, legacy degree and the rollout payload) move verbatim from app.py into modules/web_viewer/multibyte_rollout.py; BotDataViewer inherits the mixin, so callers and tests are unchanged. The mixin declares the viewer attributes it reads for mypy. app.py's imports are untouched. app.py drops to about 7,540 lines.
