- add byAgentModel endpoint and expandable per-agent model sub-rows in the spend tab
- validate date range inputs with isNaN + badRequest to return HTTP 400 on bad input
- move CostByProject from a local api/costs.ts definition into packages/shared types
- gate providerData query on mainTab === providers, consistent with weekData/windowData/quotaData
- fix byProject range filter from finishedAt to startedAt, consistent with byProvider runs query
- fix WHAM used_percent threshold from <= 1 to < 1 to avoid misclassifying 1% usage as 100%
- replace inline opacity style with tailwind bg-primary/85 class in ProviderQuotaCard
- reset expandedAgents set when company or date range changes
- sort agent model sub-rows by cost descending in ui memo
- add company existence check on quota-windows route to guard against
sentinel and forged company IDs (was a no-op assertCompanyAccess)
- fix useDateRange minuteTick memo frozen at mount; realign interval to
next calendar minute boundary via setTimeout + intervalRef pattern
- fix midnight timer in Costs.tsx to use stable [] dep and
self-scheduling todayTimerRef to avoid StrictMode double-invoke
- return null for rolling window rows with no DB data instead of
rendering $0.00 / 0 tok false zeros
- fix secondsToWindowLabel to handle windows >168h with actual day count
instead of silently falling back to 7d
- fix byProvider.get(p) non-null assertion to use ?? [] fallback
merge Usage page into Costs as two tabs ('Spend' and 'Providers'),
extract shared date-range logic to useDateRange() hook, delete /usage
route and sidebar entry, fix quota-windows bugs from prior review
reads local claude and codex auth files server-side, calls provider
quota apis (anthropic oauth usage, chatgpt wham/usage), and surfaces
live usedPercent per window in ProviderQuotaCard with threshold fill colors
adds a new /usage page that lets board operators see how much each ai
provider is consuming across any date window, with per-model breakdowns,
rolling 5h/24h/7d burn windows, weekly budget bars, and a deficit notch
when projected spend is on track to exceed the monthly budget.
- new GET /companies/:id/costs/by-provider endpoint aggregates cost events
by provider + model with pro-rated billing type splits from heartbeat runs
- new GET /companies/:id/costs/window-spend endpoint returns rolling window
spend (5h, 24h, 7d) per provider with no schema changes
- QuotaBar: reusable boxed-border progress bar with green/yellow/red
threshold fill colors and optional deficit notch
- ProviderQuotaCard: per-provider card showing budget allocation bars,
rolling windows, subscription usage, and model breakdown with token/cost
share overlays
- Usage page: date preset toggles (mtd, 7d, 30d, ytd, all, custom),
provider tabs, 30s polling plus ws invalidation on cost_event
- custom date range blocks queries until both dates are selected and
treats boundaries as local-time (not utc midnight) so full days are
included regardless of timezone
- query key to timestamp is floored to the nearest minute to prevent
cache churn on every 30s refetch tick
