# SaaS extensions and payments layer
|
|
|
|
Deliver INTENT pillar 4 (payments/metering) and routing engine v0 for
|
|
self-hosted vs SaaS backend selection.
|
|
|
|
**Predecessor:** SAND-WP-0005 (extension SDK — finished)
|
|
**Follow-on:** SAND-WP-0007 (snapshots), real E2B/Modal adapters
|
|
|
|
## Payments and credits
|
|
|
|
```task
|
|
id: SAND-WP-0006-T01
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "6a7df600-4a41-4942-8969-9e06a3b2406e"
|
|
```
|
|
|
|
`CreditsStore`, `estimate_cost` / `settle_usage`, pre-create balance check,
|
|
post-destroy debit, `SandboxStatus.meter` field. Docs: `docs/payments.md`.
|
|
CLI: `sandboxer credits show|add`.
|
|
|
|
## Routing engine
|
|
|
|
```task
|
|
id: SAND-WP-0006-T02
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "f1a81915-57b8-4a72-9ca9-bca402084b4a"
|
|
```
|
|
|
|
`RouteSpec` on profiles, `resolve_extension` with strategies
|
|
(`prefer-self-hosted`, `lowest-cost`, `lowest-latency`, `explicit`).
|
|
Docs: `docs/routing.md`.
|
|
|
|
## ext.saas-stub
|
|
|
|
```task
|
|
id: SAND-WP-0006-T03
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "91bce931-5cae-4bbf-8dce-095a603ec0da"
|
|
```
|
|
|
|
Metered SaaS stub extension — `estimate_cost`, `meter_actual`, no external API.
|
|
Profiles: `profile.saas-stub`, `profile.burst-sandbox`.
|
|
|
|
## Manager integration
|
|
|
|
```task
|
|
id: SAND-WP-0006-T04
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "7e1e9b80-0b3e-4eee-b7ac-2b611f8a0f3d"
|
|
```
|
|
|
|
`SandboxManager` uses routing resolver; destroy loads `status.extension_id`;
|
|
meter settlement on destroy; meter events to State Hub.
|
|
|
|
## Tests
|
|
|
|
```task
|
|
id: SAND-WP-0006-T05
|
|
status: done
|
|
priority: high
|
|
state_hub_task_id: "7075d8fc-44d1-48fe-b061-a05385de31a8"
|
|
```
|
|
|
|
`test_routing.py`, `test_payments.py`, `test_saas_stub.py`.
|
|
|
|

|
|
priority: low
|

state_hub_task_id: "c514c6b3-2be8-41e4-8e84-88f20ad80f7e"
