The detached prefetch spawned four codeburn subprocesses (week, 30days,
month, all) that competed with the main refresh loop's Today fetch for
disk and parser time. On large session corpora that starved the Today
refresh for minutes at a time, and the status label drifted stale until
the prefetch queue finally drained. Users perceived this as the menubar
"stopping" until they clicked a provider tab, which coincided with the
queue clearing.
Drop prefetchAll. Period tabs in the popover now fetch lazily on first
click (3-10 seconds once per app lifetime per period), same as they did
in 0.8.1. Today's label stays fresh because nothing else is hammering
the parser in the background.
Loading overlay no longer flashes on every 15s poll. isLoading now only
toggles when the cache is cold, and all periods prefetch once on launch
so tab switching is instant.
Heatmap tooltip, trend bars, forecast, and all-time stats were computing
on UTC dates while the CLI reports on local dates, so the two disagreed
at day boundaries. Switched every date formatter and calendar in these
paths to .current so the menubar matches codeburn today output.
Menubar: reduce cache TTL from 300s to 30s, background refresh from
60s to 15s, always fetch fresh data on tab switch instead of serving
stale cache. TUI: default auto-refresh to 30s (--refresh 0 to disable).
Closes#107
The tab strip was visible for everyone regardless of which tools they
actually run, which produced a row of All + one provider for Claude-only
users and a row of All + zeros for users on exotic stacks. Hide the
whole row until a second provider has real spend, matching the behavior
the GNOME extension ships with.
Also expand ProviderFilter to include every provider the CLI supports
(OpenCode and Pi were missing) so their tabs appear when those tools
produce sessions. The CLI already emits pi and opencode in the payload's
providers map; the Mac app just wasn't offering a tab for them.
visibleFilters now filters on value > 0 instead of key presence, because
the CLI includes zero-cost entries for discovered-but-unused providers
and we don't want those rendering as blank tabs.
