Two invariants the session endpoint stated but did not hold. A box runs one thing at a time. `POST /session` read `activeForBox` and refused when something was already running, but the read and the insert are two statements with nothing between them: two requests that both saw "nothing is running" each got a row, and the job poll then handed the host the same box to start twice. Demonstrated at 2 rows and 2 jobs from one box. That is the failure the state claim exists to prevent, one step earlier, and it takes the same answer — a partial unique index on the predicate the read asks about, so the database refuses the second insert. `Session.request` turns that refusal into the same 409 in the same words, so a caller cannot tell which of the two caught it. The migration resolves any existing duplicates before creating the index, keeping each box's newest unstopped run because that is the one a person is waiting on, and stopping the rest rather than deleting them. Separately, a run that reached `ended` or `failed` kept the last ticket it published. Publishing a new one is already refused, so the stale address was both the only ticket a client could read for a dead run and the one nothing was allowed to replace — and a client that polls would dial it. Terminal transitions now clear it, in `setState` as well as in the compare-and-set, so the invariant does not depend on which writer stopped the run. Seven tests, each checked against the unfixed code first. The published descriptions for the ticket field and the read endpoint now say that a stopped run has no address.
apps/api
The public HTTP API for Nestri — a Hono app deployed as a Cloudflare Worker.
What it does
Exposes the JSON API consumed by frontends and other clients. Every route is a thin wrapper that
validates input, delegates to a domain function in @nestri/core,
and returns { data: ... }. All business logic lives in the core package.
Routes:
| Prefix | Purpose |
|---|---|
/ |
Health check |
/user |
Current user profile, fingerprints, linked accounts |
/steam |
Link / sync / unlink a Steam account |
/library |
Owned games with playtime |
/games |
Game catalog |
/pairing-code |
Device pairing codes |
/machine |
Host machines |
/access-token |
Short-lived access tokens |
/doc |
Generated OpenAPI spec |

Key details
- Auth:
Authorization: Bearer <JWT>verified against@nestri/auth; or thex-nestri-admin-tokenheader (seeADMIN_SHARED_SECRET). - Errors: centralized
VisibleError→ typed JSON responses. - The API worker receives its bindings (
AUTH,HYPERDRIVE,STEAM_API_KEY,ADMIN_SHARED_SECRET) from Alchemy — seealchemy.run.tsat the repo root.
Running
Run via the root Alchemy setup (bun alchemy.run.ts --dev). Needs a Postgres database and an auth worker; see the root README for full dev setup.
