| 1 | //! What g1t pays for itself, and two caps on it. |
| 2 | //! |
| 3 | //! Every charge that settles (an agent run, sandbox time, a build) is |
| 4 | //! split by what paid for it, at cost: a customer's real money, or g1t's. |
| 5 | //! g1t's part goes to `g1t_spend` by day, bucket and billing account: |
| 6 | //! |
| 7 | //! - `comped`: work on a comped account (g1t's own, Flagon's), all of it. |
| 8 | //! - `trial`, `oss`: the trial credit and the open-source pool. |
| 9 | //! - `given`: a free workspace's overrun past its last bit of trial. |
| 10 | //! - `unpaid`: charged, but with no real money behind it: Stripe's test |
| 11 | //! key, or `FREE_WHILE_BUILDING`. |
| 12 | //! |
| 13 | //! The plan's included usage and on-demand charges with live payments are |
| 14 | //! revenue, not g1t's. A workspace's own model provider costs g1t nothing. |
| 15 | //! |
| 16 | //! Two caps read it: |
| 17 | //! |
| 18 | //! 1. **A comped account's monthly budget**: `COMPED_MONTHLY_CEILING_MICROS` |
| 19 | //! ($150), or the account's own limit in its terms (sudo, Accounts → |
| 20 | //! Terms → Limit). Staff are emailed at 50, 75, 90 and 100%, once each a |
| 21 | //! month; at 100% new work on it is refused until staff raise it or the |
| 22 | //! month turns. Work already running finishes. |
| 23 | //! 2. **The daily breaker**: when g1t's part across every workspace today |
| 24 | //! (UTC) reaches `PLATFORM_DAILY_SPEND_CAP_MICROS` ($75), new compute |
| 25 | //! that g1t would pay for (sandboxes for workflows, checks, the merge |
| 26 | //! queue and agents alike) is paused for the rest of the day: everyone's |
| 27 | //! except workspaces paying with real money on the plan or an enterprise |
| 28 | //! contract, and comped accounts, which have their own monthly budget. Staff are emailed at once and sudo |
| 29 | //! shows a red bar; staff can lift it for the day. |
| 30 | //! |
| 31 | //! Zero for either variable turns that cap off. |
