| 1 | //! Whether a workspace may start compute, and holding what it may cost. |
| 2 | //! |
| 3 | //! Every service that starts something that costs g1t real money asks |
| 4 | //! here first (see `g1t_contracts::billing::ReserveArgs`): |
| 5 | //! |
| 6 | //! - **`entitlements`**: the workspace's plan, whether it may start compute |
| 7 | //! at all, its caps (agents at once, a run's time and spend, an issue's |
| 8 | //! spend), its ceiling and exposure, and whether compute is paused. |
| 9 | //! - **`reserve`**: holds the work's estimated cost against what may pay |
| 10 | //! for it (the plan's included usage, the trial, the open-source pool, |
| 11 | //! then on-demand room under the ceiling and the spend limit), so starts |
| 12 | //! at the same moment cannot overshoot together. Answers who pays first, |
| 13 | //! or refuses with a stable code and a message for the owner. |
| 14 | //! - **`settle`**: releases the hold. The charge itself goes on the ledger |
| 15 | //! the usual way; a hold never settled lapses after three hours. |
| 16 | //! |
| 17 | //! **No card, no compute.** A free workspace's forge is free, but compute |
| 18 | //! needs the plan, or a card check: it unlocks the one-time trial and g1t's |
| 19 | //! open-source pool (checks, workflows and the merge queue on public |
| 20 | //! repositories). The card check is what keeps g1t's free compute from |
| 21 | //! being mined: one trial per card, and a real person behind each. |
| 22 | //! |
| 23 | //! **Spikes.** An hour's spend above `SPIKE_FACTOR` (5) times the |
| 24 | //! workspace's usual hour over the last week, and at least |
| 25 | //! `SPIKE_FLOOR_MICROS` ($5), pauses new compute until an owner answers: |
| 26 | //! keep going (for 24 hours, or until the hour's spend doubles again) or |
| 27 | //! stop. Runs already under way finish. g1t's own workspaces are watched |
| 28 | //! but never paused. |
