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.

ProjectsWorker mirrors DO Projects to cloud_projects table in a two-pass
sweep: upsert projects, then walk each project's resource membership
(list_project_resources) and update cloud_resources.cloud_project_id +
tenant_id. DO URN kinds get normalized via normalize_kind/1 (domain →
dns_zone, space → spaces_bucket) so attribution matches local naming.
DomainsWorker syncs DNS zones (DO Domains). Same upsert chokepoint, same
three-strike stale handling. Zones are global to the account; attribution
happens via ProjectsWorker if a domain is in a DO project, else stays
NULL pending operator classification.
Oban.Plugins.Cron added with 15-minute schedules for ProjectsWorker,
DropletsWorker, DomainsWorker — workers run automatically once a token
is configured. Phase 0/1 cadence; phase 2 moves droplets to cloud_sync_fast
(1-min) for real-time status visibility.
DigitalOcean.Client gains list_domains / list_volumes / list_floating_ips.
Volumes and floating IPs not yet wired to workers; trivial follow-on.
Live smoke test: 5 droplets + 7 DNS zones discovered, all attributed to
their existing DO projects via membership lookup (skyai-internal becomes
the fallback only for genuinely orphan resources).

Models:
- cloud_projects: arcadia-cloud's mirror of DO Projects, indexed by
(provider, provider_id); tenant_id + purpose classify each project.
- cloud_resources: single unified resource table; kind-specific bits in
attrs JSONB; first_seen_at / last_seen_at / stale_strike_count drive
three-strike deletion.
- cloud_resource_events: append-only audit (discovered, updated, deleted,
drift_detected, tagged, restored).
ArcadiaCloud.Cloud context owns the single upsert chokepoint that:
- inserts new with `discovered` event
- updates existing only when meaningful fields change
- restores tombstoned rows seen again
- bumps last_seen_at and resets strike count
mark_stale/3 implements the three-strike rule.
ArcadiaCloud.DigitalOcean.Client is a Req wrapper with auto-pagination.
Per-purpose token resolution via .Tokens (phase 1: env DO_API_TOKEN;
phase 2: vault). Per project_arcadia_cloud memory the long-term shape
is one PAT per queue purpose for rate-limit isolation.
ArcadiaCloud.Sync.Bootstrap ensures the skyai-internal DO Project exists
on first sync, idempotent thereafter. ArcadiaCloud.Sync.DropletsWorker
runs full droplet sync on the cloud_sync_full Oban queue.
InventoryController wired to real data: platform_admin sees all,
tenants see only their scope.
Live smoke test against real DO: 5 droplets synced; skyai-internal
project auto-created; events written; endpoint returns scoped results.

API-only Phoenix 1.8 project for cloud-ops, inventory, billing, and
provisioning sagas. Validates arcadia JWTs via shared Guardian secret
(verify-only; arcadia-app remains the issuer).
Deps beyond default Phoenix: guardian, cors_plug, oban, req.
Postgres on local port 5433 per arcadia stack convention.
Endpoint runs on :4005.
Endpoints:
- GET /api/health — public, returns service identifier
- GET /api/v1/inventory — auth-gated, returns empty list (phase 0 stub)
Oban configured with the queues phase 1+ will need:
provisioning / cloud_sync_fast|full|slow / cloud_billing / metering.
