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.
Wire contract targets api.codeburn.app/v1/telemetry (Worker follows).
Root cause of the field-reported 45s timeout + perpetual slowness: on
a cold cache all six sections spawned different CLI subcommands at
once, each running its own full-history parse (~11-31s, ~3GB RSS),
contending past the 45s kill so the rebuilt cache never persisted and
every poll restarted from zero.
- the first overview fetch runs as a warmup: 10-minute timeout,
re-arms until it succeeds, reverts to 45s after; section polls gate
on that first resolution (usePolled gains enabled), so cold
hydration happens exactly once
- warmup streams the CLI's progress protocol; the splash shows 'First
run: indexing your usage history' with a per-provider ingest list
(logo, live counts, check on done), static under reduced motion,
generic fallback without events; warm launches unchanged
- overview spawns pass --no-timeline (desktop never renders it)
Measured on real data: cold 31s once (was: killed at 45s forever),
warm 2.6s. 295/295 app, 1797 root.
The motion batch gave five sections shimmer skeletons on first load but
missed Compare and Models' Audit lens (both still showed bare loading
text in an empty panel). Same SectionSkeleton treatment now.
250/250.
- Provider filter: Models-this-period sources current.topModels (history
days carry empty topModels per provider); StackedBars falls back to a
cost-proportional single segment like the Swift menubar
- Chart windows align to the CLI (week -7, 30days -30, all = 6 months)
and zero-fill a contiguous calendar window; history.daily is sparse and
both sides key local YYYY-MM-DD, so lookups are safe (verified on real
CLI output)
- Custom range threads into Overview panels (chart, models table) and
suppresses MTD/projected and vs-last-week comparisons; Compare states
that custom dates fall back to the period
- usePolled clears errors per attempt and sections show a StaleBanner
instead of silently rendering last-good data after a failed refresh
- Cache-hit denominator matches the CLI; hero savings relabeled 'Saved by
applied fixes' + new 'Saved via local models' line; formatCompact
everywhere; Optimize 'Fixes' count matches the rendered list
App suite 163/163 (was 147), root 1613/1613.
- new Dropdown component (our .pop menu style, keyboard-accessible) replacing
every native <select> (currency, period, plan preset, export, Compare pickers)
- expand currencies to 30 common ISO codes (engine handles any valid currency)
- fix the Settings pane so rail + content anchor top-left and fill the area
typecheck clean; 128/128 tests pass.
Search (project/model/id), sort (cost/recent/turns/tokens), group-by-
provider toggle, and a summary bar (count · cost · tokens) over the
filtered set. Dependency-free "show more" paging keeps large lists fast;
provider headers are sticky and the list flows in the page scroll.
Richer detail: 8 real stat cards (cost/calls/turns/saved/input/output/
cache read+hit%/cache write), full date range + duration, Esc-to-back,
selection tracked by id so background refreshes keep the detail live.
Centralizes formatCompact/date/duration helpers in lib/format ("184K"
not "0.2M"); Compare now uses the shared helper. Search-aware empty state.
Sessions: provider-grouped list of every session in range (project,
models, turns, cost, tokens) with a lightweight real detail — no
fabricated titles, no unbacked context-window widget.
Compare: two-model picker (defaults to top two by cost) across
Performance, Efficiency, Category head-to-head, Working style, and a
derived Context panel, all mapped straight from `compare --format json`.
Nav reordered to match the design: Overview, Sessions, Spend, Optimize,
Models, Compare, Plans, Settings (⌘1-7).
