Multi-vendor AI usage tracking — one trustworthy number for cost, usage, and identity across tools

The hard part of this system isn't the dashboard — it's making messy, inconsistent, late-arriving data from multiple vendors converge into something you can act on without silent failures.

• Canonical event schema — every vendor (ChatGPT, Copilot, Cursor) maps into one AIUsageEvent shape; adding a new vendor is one new parser file, nothing else changes
• Deterministic deduplication — hashed dedup_key per event; same event delivered twice is recognized and skipped, never double-counted
• Late-cost backfill — billing lag treated as a patch on the existing row, not a new duplicate event
• Drift detection — baseline key-paths recorded per vendor on first ingest; any silent field rename or removal raises DRIFT_DETECTED instead of quietly writing zeros
• Proof-based identity resolution — the same human appears under different IDs across tools; identities are only linked when there's an explicit recorded proof type, never a fuzzy guess
• Snapshot regression harness — pytest snapshots ensure fixing one vendor's parser can't silently break another's output
