Three hardening fixes from adversarial review of the no-data rendering:
dataStartKey returns null at the payload's 365-entry history cap, where
the oldest retained entry is no longer the true data start; classifying
past it would label real aged-out history as no data on long custom
ranges. Documented that the install-to-first-use gap reading as no data
is literally accurate: nothing was recorded then either.
The dash granular chart now trims leading zero-only buckets by value
instead of comparing bucket timestamps against date keys, so producer
and viewer timezone skew can never drop a real first-day bucket, and an
all-zero series lands in the established empty state.
StackedBars no-data columns expose their state via aria-label, not only
a title on a non-focusable div.
Days before the first recorded day in history.daily were painted as a real
0.00/0 calls in the daily activity heatmap and the daily spend charts. That
zero is unknown, not measured, so those cells and bars now read "No data
recorded" instead of a currency zero. Genuinely idle days within recorded
history stay as real zeros.
- app: heatmap cells, the daily spend bars, and the daily-by-model columns
get a distinct no-data style plus a "No data recorded" hover for days before
the first recorded day.
- dash: the granular line chart drops buckets before the first recorded day so
no flat zero line is drawn before any history exists.
- data-start is derived in the UI layer from history.daily; payload shape is
unchanged.
Verified: app vitest 418 pass (7 new for the no-data behavior); app, dash, and
root typecheck clean; dash and app renderer vite builds succeed.
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.
Root causes (verified live): the Claude keychain branch was never
enabled (allowClaudeKeychain never passed), security -w returns
hex-encoded JSON the parser rejected, and Codex had no keychain
discovery at all.
- shared readKeychainPassword: Apple-signed /usr/bin/security, 90s
window so the user can answer the macOS dialog, hex decode,
notFound vs accessDenied classification; secrets never logged
- Claude: keychain fallback active (gated to explicit Refresh so
launch never ambushes with a dialog); connection retained across
keychain-less background polls
- Codex sources in order: the menubar's own cached OAuth (read-only,
401 = one re-read, never rotate), legacy ~/.codex/auth.json
(writable), com.openai.codex plaintext if usable; Safe Storage
never decrypted
- new accessDenied state (amber, 'locked') + ConnectAffordance on
Plans cards and Settings rows: login command, keychain-Allow note,
force Refresh
Live verification: Claude connected with its real tier and windows;
Codex correctly accessDenied until the keychain dialog is allowed.
273/273 (26 files), typecheck + build green.
- one gate (motionEnabled): off under reduced-motion, missing matchMedia,
and vitest; every path checks it first
- mount/filter-change only: count-up and bar grow-in key off the
period|provider|range key, so 30s poll refreshes snap values silently
instead of re-animating
- first-load skeleton shimmer replaces bare scanning text (kept sr-only
for screen readers); slide-in toast host for Settings/export feedback
(validation errors stay inline); CSS hover-lift + press micro-
interactions, all with a reduced-motion escape hatch
- gsap 3.15.0 + @gsap/react 2.1.2 (+74KB raw JS; G4 flame work shares it)
244/244, typecheck + build green.
- Models gains an Audit lens: raw provider token fields vs displayed
totals and cost derivation per model, est badge where pricing is
missing or recomputed cost diverges from attributed
- Settings Pricing pane: list/add/remove price overrides (USD per 1M),
inline confirm on remove, only provided rates sent; rates validated
finite and strictly positive on both sides of the bridge
- four new IPC channels with the established validation pattern
Root 1617/1617, app 235/235, build green.
- Settings/General: Daily budget row (Off / USD amount / Tokens),
positive-finite validation, warns at 80% and alerts at 100%
- app-wide one-line banner above every section: --warn at 80%+, --bad
at 100%+, dismissible for the rest of the day
- USD caps compare raw USD against per-provider daily cost (works under
any filter); token caps evaluate only on the all-providers view since
provider-filtered history zeroes token fields (comparing against a
false zero would always pass)
212/212, build green.
- TopBar picker (shown only when >1 Claude config dir exists) threads
--claude-config-source through getOverview; synthetic 'All Claude
configs' entry returns to the aggregate default
- config id validation accepts the real <kind>:<16hex> id shape while
still rejecting flag-shaped input (leading char anchored)
- both incompatibility directions handled: selecting a config resets a
non-Claude provider filter, and picking a non-Claude provider clears
the config scope, so the CLI rejection is unreachable
- choice persisted (localStorage); active config shown in the scope
line and read-only in Settings/General
Verified live against 2 real config dirs. 205/205, build green.
- will-navigate/window-open denied; openExternal restricted to http(s);
production CSP drops 'unsafe-inline' scripts (dev-only Vite plugin
re-adds it for the Fast Refresh preamble)
- single-instance lock; before-quit reaps in-flight CLI children; 16MB
output cap rejects with CliError 'too-large'
- read-only CLI spawns coalesce: concurrent identical calls share one
child, a 5s result cache absorbs same-cadence pollers (six sections
polled getOverview independently); actions bypass and flush the cache
on completion so post-action refetches are fresh
- every renderer-supplied argv string validated (period/provider/range/
currency allowlists, no flag-shaped tokens, absolute export path) with
new CliError kind 'bad-args'; envelope + action stderr routed through
sanitizeError
- quota force-refresh: manual refresh (refreshToken) passes force which
invalidates QuotaService's cache; steady polls do not
- POSIX credential mode check gated off on win32
App suite 190/190, build green (production index.html verified strict).
- formatUsd applies the payload currency {code,symbol,rate} once at
display; formatConverted (symbol only) for CLI-preconverted plan
values so nothing converts twice
- provider picker built from providerDetails: label shown, internal id
sent as --provider (fixes filters for providers whose display name
differs, e.g. Grok Build); falls back to map keys on older CLIs
- getYield threads the active provider through preload/main/sections
App suite 170/170, root 1615/1615.
- 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.
contiguousDailyWindow rebuilt a calendar window from the client clock and looked
up days by date key; on real CLI data every lookup missed and zero-filled, so the
Spend chart went empty and the Overview chart went flat. Use the real last-N
backfilled entries of history.daily directly (Spend last-15, Overview
last-max(30, periodDaily)) and remove the dead helper.
typecheck clean; 147/147 tests pass.
Port the menu bar's OAuth quota fetch to the Electron main:
- app/electron/quota/{claude,codex,index,security}.ts reads the local Claude/
Codex credentials, hits the usage APIs, normalizes to QuotaProvider (5h/weekly
windows, auto-detected tier, resets-at) with 429 backoff + single-flight
- getQuota IPC bridge (main + preload + renderer types); needs a full relaunch
Security: tokens are never returned or logged (redact Bearer/sk-ant/sk-/JWT,
strip NUL, truncate 240); credential reads refuse symlinks (O_NOFOLLOW/lstat) and
insecure modes; Anthropic refresh is never POSTed (single-use, shared with CLI).
typecheck clean; 147/147 tests pass; Electron build passes.
- extract contiguousDailyWindow + formatChartDate to lib/period (shared)
- Spend "Daily spend by model": fixed contiguous 15-day window (zero-filled)
with an .ov-xax date axis, matching the Overview chart
- remove the horizontal gridlines from both charts (they read like data lines)
typecheck clean; 129/129 tests pass.
- share a shortenProjectPath helper (Sankey + Sessions) so rows show
"projects/eywa" instead of the dash-mangled full path
- fixed-column table layout so values align and stop shifting row-to-row
- TUI-style inline row expansion: click a row to unfold its 8-stat detail in
place (one at a time, chevron + aria-expanded); replaces the navigate-away view
typecheck clean; 128/128 tests pass.
- add a shell.openExternal bridge (main ipc handler + preload + renderer type)
so links open in the default browser (requires a full relaunch)
- wire the sidebar social icons to real URLs and add LinkedIn
- AboutModal: flame + wordmark, version, tagline, the five social links, and a
"Check for updates" link to the GitHub releases page
typecheck clean; 128/128 tests pass.
Fable was bucketing into grey "Other" despite being a large chunk of spend.
- add `fable` SeriesKey across modelSeries.ts (label, css-var, class, matcher)
- validated CVD-safe --s-fable token (aqua #1baf7a light / #199e70 dark) in all theme blocks
- StackedBars now uses a fixed CVD-safe series order [opus, fable, haiku, gpt, sonnet, other]
for both legend and stack, so aqua never sits adjacent to the magenta (Sonnet)
typecheck clean; 128/128 tests pass.
- Plans tab: add/remove budget presets via `plan set`/`plan reset`, lists
configured plans, links to the full Plans screen
- Export tab: format + provider + native folder picker (electron dialog)
→ runs `codeburn export`, reports the result
- Devices: real Remove (`devices rm`) + Refresh; visibility is read-only
from `share status`; pairing shows an honest "pair from terminal" note
instead of a dead Approve button; combine row is read-only status
- Apply the persisted theme at app startup (not only when General mounts)
- Settings gets onNavigate for the "Open Plans" link
Only one-shot, non-interactive CLI commands are wired as buttons; the
interactive share daemon and pairing flow stay honestly read-only.
Settings was a dead shell (rail didn't switch, all buttons disabled).
Now the rail navigates and four tabs are wired to the real CLI:
- action bridge: spawnCliAction + runAction (text output, not JSON) with
getAliases/getProxyPaths reads and setCurrency/resetCurrency/addAlias/
removeAlias actions
- General: theme switcher (System/Light/Dark, persisted) + live currency
(reads status, changes via `currency`) + default-period preference
- Providers: real detected-tools list with spend
- Model aliases: full add/remove against real config
- Privacy: honest local-only info
Devices content preserved as-is; Plans/Export are placeholders for Part 2.
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.
Adds getSessions / getCompareModels / getCompare IPC channels (argv for
the new CLI JSON emitters), mirrors SessionRow + compare-stats types into
the renderer, and — in Vite dev — resolves the repo's own dist/cli.js so
newly-added commands work without setting CODEBURN_BIN.
- Period seg now uses the 5 real CLI periods (Today/7D/30D/Month/6M);
6M maps to 'all' (matches the menubar).
- Provider control is a real dropdown listing only DETECTED providers
(accumulated from current.providers so it never shrinks) + All.
- New RangeCalendar: month grid with click-and-drag range selection
(+ two-click fallback, future-date disabling) behind a calendar button;
commits a custom {from,to} threaded to Overview/Spend/Models/Optimize
via new --from/--to CLI args (Plans/Settings stay period-only).
- typecheck clean, 87 vitest pass.
macOS uses titleBarStyle hiddenInset so the traffic lights float over
the sidebar (Linear/Hermes-style), with the sidebar top inset to clear
them and the top chrome marked -webkit-app-region: drag (interactive
controls stay no-drag). Windows/Linux keep their native frame + controls.
Exposes process.platform through the bridge and tags <html data-platform>
so CSS adapts per OS. typecheck + 82 tests green.
Install an app menu without the CmdOrCtrl+R reload accelerator so ⌘R reaches the renderer for
in-place refresh (keeps Edit/Window roles + dev DevTools). Model labels are now family-level
("Opus"/"Sonnet"/"Haiku"/"GPT / Codex") and the Sankey shows the real model id instead of the
wireframe's sample version names. Optimize retains last-good yield across 30s revalidation (no
flicker to "—"). Removed hints for unimplemented ⌘K/⌘E/esc; fixed stale TopBar comment.
Implemented by Codex gpt-5.5 (high); committed by Fable (git blocked in Codex sandbox).
Settings rail (Devices active) with This device (getIdentity), Discovered nearby
(new getDevicesScan bridge → `codeburn devices scan --format json`), and Paired
(getDevices perDevice). Pairing/approve/pull/visibility/combine are M1 visual
affordances (mutations = M2); share status is process-local so not shown as
authoritative. Settings uses a title-only bar (no period/provider).
Implemented by Codex gpt-5.5 (high); committed by Fable (git blocked in Codex sandbox).
Addresses T3 review: full test coverage for all lenses + empty/error states, segment
color mapping, Sankey ribbon properties, and lib/period.ts across all windows; Sankey
ribbon widths now truly proportional (removed the 28px cap) and labels are pretty/basename
+ truncated so real ids don't clip; legend reflects present models; honest "top N" project count.
Implemented by Codex gpt-5.5 (high); committed by Fable (git blocked in Codex sandbox).
Period-sliced StackedBars (history.daily[].topModels within the selected window via
a new shared lib/period.ts), the By-project list, and a Sankey rendered dynamically
from getSpendFlow (per-model hue ribbons). Lens tabs; series palette shared with the
legend. Adds a neutral .s-other class for the rollup segment.
Implemented by Codex gpt-5.5 (high); committed by Fable (git blocked in Codex sandbox).
- main.ts: 1200x820 BrowserWindow (contextIsolation:true,
nodeIntegration:false, sandbox:true), loads the Vite dev URL or the
built index.html, registers one ipcMain.handle per CodeburnBridge
channel, and starts a 30s tick that emits `codeburn:refresh`.
createBridgeHandlers() is a pure, injectable channel→argv map so the
spawn→IPC wiring is unit-testable without a GUI (main.test.ts).
- preload.ts: exposes window.codeburn (CodeburnBridge, exactly) and
window.codeburnEvents.onRefresh via contextBridge. Handlers return an
{ok,value|error} envelope so the structured CliError kind survives the
world boundary.
- types.ts: mirrors MenubarPayload/DailyHistoryEntry/DailyModelBreakdown
and the other CLI payload types verbatim, plus the exact CodeburnBridge
interface and Period union.
- ipc.ts: typed 1:1 wrapper + normalizeCliError.
