| 1 | //! What g1t earns on each thing it sells, measured against what |
| 2 | //! Cloudflare actually charged for it. |
| 3 | //! |
| 4 | //! Once a day, after `costs` has read Cloudflare's bill, the reconciler |
| 5 | //! puts three figures side by side for every day and each of g1t's |
| 6 | //! products (a "bucket": sandboxes, deployments, git, repository storage, |
| 7 | //! …): |
| 8 | //! |
| 9 | //! 1. **What Cloudflare charged**: the day's cost lines `cost_map` gives |
| 10 | //! the bucket. |
| 11 | //! 2. **What g1t's meters recorded**: the cost on the ledger's entries for |
| 12 | //! it (the price book's cost at the time) and, where a mapping names |
| 13 | //! one, g1t's own count of the same units (git operations). |
| 14 | //! 3. **What customers were charged**: the entries' value at price, before |
| 15 | //! the plan's included usage, a trial or a pool paid part of it; and of |
| 16 | //! that, what workspaces paid. Month-end meters (git, storage, scans, |
| 17 | //! embeddings, the actions cache) come from daily snapshots of what they |
| 18 | //! had come to (`pending_days`). The plan's price is the `platform` |
| 19 | //! bucket's: the plan pays for running g1t. |
| 20 | //! |
| 21 | //! From those: margin per product (value against cost) and for all of g1t |
| 22 | //! (money in against every cost); drift (counts or costs that disagree past |
| 23 | //! a mapping's threshold, and leaks: cost with no revenue, or a Cloudflare |
| 24 | //! meter no one mapped); each workspace's cost, Cloudflare's figure shared |
| 25 | //! out by each workspace's own meters; and price proposals when a unit's |
| 26 | //! real cost has moved (`pricing`). Alerts go to staff by email and as a |
| 27 | //! banner in sudo. See docs/BILLING_OPERATIONS.md. |
