Every repaint re-rasterized every row and re-ran every layout; every
screen open re-scanned the whole history. Now work is done once per
change instead of once per frame:
Render pipeline — a content-keyed ANSI cache in render_to_ansi (every
Text/str row app-wide), memoized corner glow, and panel-wrap memos for
the base frame and stacked dialogs, all dropped on a platform switch or
emoji recalibration. Idle-frame compose falls 5-100x per screen
(contacts 5.6->0.1 ms, record card 8.5->0.07 ms, trace 7.6->0.6 ms).
Repository — an observed_at index turns every since-window query into a
range walk (recent_observations 7.5->1 ms); heard_nodes and first_seen
aggregate in one streaming pass by ISO-string comparison instead of
hydrating dataclasses and sorting; node_names groups in SQL (NOT
INDEXED past a slow planner choice).
Per packet — livefeed no longer repaints on events that drew nothing,
the channel list's stats TTL rises above the tick so the repository is
not queried per frame, watch-store alerts batch through the throttled
flush instead of a full-state disk write per new node, and the header's
360-bucket histogram/flags tuples are memoized per minute and packet.
Per open — the resolvers, topology canonical()/display_name(), and
Yen's route search memoize over their frozen inputs; timemachine, chat,
and livefeed drop duplicate queries; the config editor, device actions,
info, advert, and tx-optimize reuse the devstate session cache instead
of re-asking the radio.
Per frame, per screen — dashboard folds five window scans into one
digest; walk caches everything derived from its frozen graph (the
onward-count quadratic included); packet viewer, record dialog, trophy
rows, trace stats/log, and the node-detail route fan memoize on their
frozen inputs, invalidated by revision counters where the input can
move.
