Energy (field report: ~3x Chrome drain):
- polls skip entirely while the window is hidden/minimized, with one
catch-up refresh on return when data is stale; visible-but-unfocused
keeps polling (second-monitor case)
- all looping animations pause under html.page-hidden (the sidebar
flame flicker was a perpetual compositor drain)
- default cadence 60s; an explicit stored choice is always honored
Currency (field report: set USD, still saw EUR):
- memo-served payloads re-applied their embedded stale currency; config
mutations now purge the renderer memo and force-refresh, and a
switching payload can never overwrite the applied currency
- USD default verified end to end
Measured: hidden window = 0 new CLI spawns over 5 cadences (was: full
polling forever). App 340/340, build + package green.
Performance and coherence:
- Settings > General 'Refresh every' (Manual/30s/1m/3m/5m/10m), live via
RefreshCadenceContext; Manual polls only on demand
- usePolled memoKey LRU: provider/period switches paint the last-good
result instantly with a switching hairline while refreshing quietly
- quota TTL 5min + honest rate-limited copy on 429 backoff
- version-suffixed cache files (session-cache.v5.json, daily-cache.v12,
auto-minted on future bumps); legacy files never written or deleted,
adopted once when versions match: old and new binaries coexist
without clobbering (field-observed menubar-vs-desktop ping-pong)
- advisory hydration lock: concurrent cold starts share one scan
(wait-then-read-warm), stale/dead locks self-heal, never a
correctness gate
Telemetry v1 + onboarding (desktop only, per owner decisions):
- first-launch onboarding (3 feature screens + consent); region-split
default (EU/EEA/UK/CH off, elsewhere on, unknown off); nothing sends
before consent completion or while off; dev builds never send
- anonymous install UUID, rotated on opt-out; day-granularity events,
cost buckets only; whitelisted names; 200-event queue, 5min flush
- Settings > Privacy live toggle replaces the static claim
Zero computed-number changes. App 316/316, root 1805.
