* fix(app,dash): render pre-history days as no data, not a currency zero
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.
* no-data: cap guard, timezone-free dash trim, StackedBars aria
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.
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.
- 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.
- Sessions: All + per-provider logo buttons (detected, cost > 0) that
drive the same app-level provider state as the top-bar dropdown, so
the two controls can never disagree; aria-pressed group semantics
- Spend By project: rows expand inline (single-open, aria-expanded,
chevron rotation) to the project's sessions: date, top model, calls,
currency-aware cost; date-only strings parsed at local noon so days
never roll across time zones
194/194, typecheck + build green.
- 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.
- 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.
By-project and the Activity/Tools/MCP/Subagents breakdown panels cap at 300px
with a slim internal scrollbar, so they stay a consistent compact size instead
of growing unbounded with the data.
typecheck clean; 126/126 tests pass.
Drop the Projects/Activity/Tools/MCP/Subagents lens tabs. Everything shows on
one scrolling page: chart + By-project, Cost-flow Sankey, then the breakdown
sections in a responsive grid. Empty sections are hidden. All reflects the
selected date range.
typecheck clean; 128/128 tests pass.
The StackedBars chart lived in a fixed 96px band, so when the grid
stretched its card to match the taller "By project" panel the bars
floated at the top over a large empty gap. Make the panel/body flex so
the chart fills the card height (min 120px) with bars bottom-anchored;
round stacked-segment corners only at the top/bottom of each column.
- 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.
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.

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.
