Wanjohi bbe729e5c7 feat(api): the session endpoint, and a claim that only one caller can win
A run of a box had core support and no HTTP surface. This adds both halves
of it: a person asks for a run and reads it back, and the host agent the box
is placed on is handed the work and reports what happened.

The access rule is the point. An agent may only see or touch a run whose box
is placed on its own hardware, and that is a `where` clause on every one of
the three agent endpoints rather than a check next to them — host credentials
are long-lived secrets sitting on hardware in somebody's home, so what one
leaking can reach has to be decided by the query. "No such run" and "not your
run" are the same refusal, so ids cannot be discovered by reporting states
at them.

`Session.setState` updated on the id alone, which means two agents polling
the same work both succeed and both start the same box. There is one host
today, which is exactly why that would have been built wrong and stayed
wrong. The state a run is moving out of is now part of the `where` clause,
so the database picks the winner; the loser gets a conflict rather than a
silent no-op. Three cases that look alike are kept apart: re-reporting a
state you already reported changes nothing and is not an error, a transition
that does not exist is refused with the run left where it was, and another
host reporting anything is forbidden.

Asking for a run makes no decision about where it happens — a box already
names its hardware, so the run inherits it by join. Placement therefore
gets an interface at box creation, where the decision actually is, with the
single-host case as its implementation and a deliberate refusal when there
is more than one candidate and no policy to choose with.

Tests cover the wire shape from both sides, the query scoping, the claim,
and the timestamp idempotence a run's billing rests on.

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 typed fn() 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 from AsyncLocalStorage (set by the API middleware / auth worker) without passing it through call chains.
  • Soft delete: every table has time_deleted; queries filter with isNull(table.timeDeleted).
  • IDs: ULIDs via Identifier.ascending('user')usr_....
  • Tables are defined in *.sql.ts files (drizzle) with namespaces in index.ts.
  • Environment is read through Env.get(), init by worker bindings.
