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.
packages/core
@nestri/core — the domain layer for Nestri. All business logic, database access, and
serialization lives here. The API and auth workers are thin pass-through translation layers on top.
What it contains
| Area | Files | Purpose |
|---|---|---|
| db | db/index.ts, db/types.ts, db/test.ts |
Drizzle + Postgres (Database.use/transaction), ULID column helpers |
| users | user/* |
Users, linked accounts, fingerprints, library |
| teams | team/* |
Teams + membership with roles (team_member) |
| games | game/* |
Game catalog, depot content, per-host downloads |
| steam | steam/index.ts |
Steam API integration & SSH identity resolution |
| auth | auth/subjects.ts |
JWT subjects shared with the auth worker |
| infra | env.ts, context.ts, actor.ts, fn.ts, id.ts, error.ts, examples.ts |
Environment, Actor model, zod-typed fn() wrappers, IDs, error types, examples |
| migrations | migrations/ |
Drizzle-kit SQL migrations for Postgres schema |
Conventions
- Domain namespaces (
user/,team/, ...) expose typedfn()functions that validate input with a Zod schema and serialize DB rows inside the function boundary — the API routes never see raw table rows. - Actor model:
Actor.userID,Actor.type, ... pull the current authenticated identity fromAsyncLocalStorage(set by the API middleware / auth worker) without passing it through call chains. - Soft delete: every table has
time_deleted; queries filter withisNull(table.timeDeleted). - IDs: ULIDs via
Identifier.ascending('user')→usr_.... - Tables are defined in
*.sql.tsfiles (drizzle) with namespaces inindex.ts. - Environment is read through
Env.get(), init by worker bindings.
