Three new schemas: - cloud_balance_snapshots — hourly MTD balance/usage poll for live-accrual. - cloud_invoices — header per provider invoice, with ingest status flags. - cloud_cost_lines — per-line-item COGS, FK to cloud_resources where matched. Three new Oban workers (queue: cloud_billing): - BalanceWorker (hourly) records a snapshot. - BillingHistoryWorker (daily) discovers invoices via /v2/customers/my/ billing_history, upserts headers, enqueues an InvoiceIngestWorker for each not-yet-ingested invoice. - InvoiceIngestWorker (per-invoice) fetches /invoices/:uuid/csv, parses with NimbleCSV (header-keyed so column order shifts don't break us), replaces the invoice's line set, then matches lines to cloud_resources by (kind, name) — case-insensitive, name extracted from "name (size)" description format. DigitalOcean.Client gains get_balance / list_billing_history / get_invoice_summary / fetch_invoice_csv. The CSV endpoint returns text/csv so we bypass Req's body decoder. Cron additions: BalanceWorker hourly at :07, BillingHistoryWorker daily at 02:23. API: - GET /api/v1/billing/balance — latest snapshot, platform_admin only. - GET /api/v1/billing/cost-lines?period=YYYY-MM-DD&kind&limit — per-line COGS, platform_admin only. Live smoke against real DO billing API surfaced and fixed three CSV-format gotchas: column headers use underscores not spaces (group_description, project_name), USD column has $ prefix, dates use "YYYY-MM-DD HH:MM:SS +0000" format (space separator + RFC822 offset). Verified: 137 historical invoices discovered going back to 2014; April 2026 invoice (33 lines, $86.92 total) ingested with 6/33 lines matched to current cloud_resources. Unmatched lines are correctly historic droplets, Spaces buckets (not yet synced), and GST. NimbleCSV ~> 1.2 added as a dep. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
