Implements the ByteTinker-Bold distribution-agreement billing math and surfaces it on a standalone admin-only route. No UI (the API figure is the deliverable). Server-side only. Contract math (lib/billing.js, config-driven; defaults ARE the agreement): - ASD (per device/day) = min(1.0, online_seconds / (hours*3600)) # 28800 default - BillableScreens (per month) = round-half-up( Sum ASD / days_in_month ) - Flat tier (not marginal): 1-499 $1.50 / 500-999 $1.25 / 1000+ $1.00; cost = screens*rate. Single global rate card for now (per-tenant is a future concern; noted in code). Data foundation: - New durable rollup device_usage_daily(device_id, day 'YYYY-MM-DD', online_seconds), index on day. status_log (3d) / telemetry (24h) can't back a billing month. - Accumulated INCREMENTALLY off the heartbeat tick from the live connection map (same source as devices_connected) - never reconstructed from logs. Each tick credits every connected device's today-row (min(86400, +elapsed)), chunked + transactional (non-blocking); per-tick credit capped (accrualCapSeconds) as a stall/restart guard. - Retention ~400d, pruned via chunked-prune (pruneUsageDaily in runMaintenance). API: GET /api/billing/usage?month=YYYY-MM (default current), requirePlatformAdmin, mounted SEPARATELY from /api/status (billing is revenue data + a heavier aggregate; must not touch the hot status path). Reads the rollup only. MTD figure averages over COMPLETED days only (today shown in `daily` but excluded until it completes); is_final + billable_screens_final appear once the month completes. Tests (12): ASD math; billable round-half-up; flat tier/cost boundaries; accumulator (accrues by interval, caps at 86400/day, disconnected doesn't accrue); report MTD-excludes- today + final-month is_final; retention prune; endpoint authz (admin 200 / non-admin 403 / anon 401) + billing absent from /api/status. Suite 301/301. First-full-month caveat + formula in docs/billing.md. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> |
