The update Download button opened the GitHub release page; it now
downloads the right artifact for the running platform directly: arm64
or x64 dmg on macOS (preload newly exposes process.arch), the Setup exe
on Windows. Linux keeps the release page since it ships three formats
and the user picks. Unknown platforms and preloads without arch fall
back to the page. URL mapping is unit-tested per platform.

Checks the GitHub releases for newer desktop-v tags once per launch
and every 24h (15s timeout, no identifying headers, offline = silent
retry). A dismissible banner and a Settings About row surface the
newer version and link the release page; dismissal persists per
version so each release nags at most once. No auto-install: unsigned
builds cannot, by platform constraint; the checker only notifies.
App 364/364 (+24), typechecks + build green.
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.
- prefetch fires exactly once per provider per session; memo sized to
detected providers so base keys never evict (was: 12 full-history
parses every 30s forever from LRU thrash re-triggering the effect)
- day-aggregator buckets whole turns by user-message timestamp,
matching the report/headline path: trend bars and provider breakdown
now reconcile exactly (midnight-straddling turns were split);
DAILY_CACHE_VERSION 13 with an IANA tz guard that rehydrates when
the cache crosses timezones
- overview's redundant second all-provider scan collapsed (~11% faster
warm); numbers parity-guarded
- lock takeover cleans stale hydrating.lock; SIGINT/SIGTERM release it
- scanner skips EPERM/EACCES provider dirs (progress shows skipped)
instead of aborting; onboarding hints Full Disk Access
- rateLimited quota copy render tests; export -f json emits valid
empty JSON when no data
Root 2023 (+4), app 327 (+3), typechecks clean.
P0: an interrupted cold hydration left partial caches that the
emptiness check read as warm — the daily backfill froze (missing older
days) while session parsing healed gradually (drifting totals),
poisoning every surface sharing the cache. Both caches now carry an
explicit complete marker: partial resumes cold under the hydration
lock; unmarked caches self-heal with one re-hydration. Regression test
seeds the exact frozen artifact and asserts bit-for-bit convergence
with a never-interrupted run.
- splash indexing reveals only on genuinely cold scans (explicit cold
flag in the progress protocol), never on warm incremental re-parses
- uncached filter switches clear to skeleton instead of showing the
previous filter's numbers; cached switches paint same-commit;
background prefetch warms every detected provider after idle
- build stamp (git sha + date) in splash and About ends build ambiguity
- payload parity test: identical payloads on identical cache, and
payload totals equal the CLI report path
- Sessions empty state keeps the provider filter row; zero savings
line hidden; TCC usage-description strings + Full Disk Access docs
- warm profile documented: optimize scan ~1.47s dominant (safe
refactor deferred), parse ~1s, aggregation ~30ms
Root 1848, app 320, typechecks clean.
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.
- 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.
Review of T0 (Electron scaffold) approved with one Important finding + cheap
Minors. All fixes scoped to app/.
- usePolled: replace per-call cancel closure with a generation/epoch counter so
an orphaned in-flight fetch (from refresh() or an interval tick, discarded
cancel handle) can't resolve after a newer fetch and clobber fresh data. New
TDD race test (slow deps-A resolves after fast deps-B; keeps B).
- cli: nvm resolution now scans version dirs descending and takes the first
whose bin actually contains codeburn (was lexicographic max, unverified),
matching CodeburnCLI.swift. Export nodeManagerDirs + hermetic nvm test.
- index.html: tighten CSP connect-src ws: -> ws://localhost:5173.
- preload: import type { Envelope } from main instead of redeclaring it.
- main.test: table-driven channel->argv assertion over all 9 codeburn:* channels
plus a keys check and a non-spawning cliStatus case.
Ports the wireframe window shell into React with exact markup/classes:
- Shared components: Window, Sidebar (traffic lights, gradient mark, six
nav items with ⌘ keycaps + active `on` rail, status line), TopBar
(title, scope, period SegTabs Today/7D/30D/Month/6M/Custom, ProviderPop),
Panel, Stat, SegTabs, ProviderPop, Hint.
- usePolled(fetcher, deps): generic 30s poll + loading/error state,
errors normalized to CliError.
- App.tsx: local section state switches the content outlet; the Overview
placeholder round-trips getOverview('30days','all') and renders the raw
current.cost, with an honest first-run "locate CLI" state when the
codeburn binary isn't found (never a crash).
- Sidebar.test.tsx: six nav items, click routes onNavigate, active `on`.
