Nine commits, in the order they are easiest to read.
## The shared operator secret is gone
`x-nestri-admin-token` had no caller left — the device pairing it
existed for is
on hold, and nothing in any tree sent it. What remained was a key that
bypassed
authentication entirely and was required to boot.
Every route behind it had a better answer. The two Steam sync routes
took a
`userId` **in the body**, so one secret could write into anybody's
library; they
now authenticate as the host holding that person's Steam sign-in, and
the claim
is checked against the enrolment record. Download-state narrows to hosts
alone.
Creating a game by hand is deleted (syncing already upserts the
catalogue), as is
reading the waitlist — every address on it belongs to someone who has
not agreed
to anything, and answering it over HTTP made that list something a
leaked key
could drain.
Nothing in the API now accepts a credential standing for more than one
caller.
## An organisation owns hardware
Two kinds of machine were modelled as one. A host somebody brings is
theirs,
reached through a team, and should die with their account. A host bought
to serve
other people's workloads is none of those things, and had to be
registered under
an employee's personal team — where their account going away took it
with them.
Ownership is now an either/or, enforced by a check constraint rather
than a
convention: both null is a host nothing can bill, and both set is two
answers to
"whose is this?". Membership of an organisation is derived from a
verified email
domain rather than stored, so signing in with a personal address still
gets an
ordinary personal account.
Not a billing subject. A team pays for what it uses either way.
## Burn, and the three windows
The unit is one second of a reference session, so an allowance is
measured in
time and a bar prints the stored number rather than converting into it.
Counters are stored beside the time they began, and a total whose stamp
has
rolled outside its window reads as zero — so a window clears without
anything
running. No schedule to misfire, no race between a reset and a write.
Two rules on the allowances are enforced rather than remembered: an
allowance
must exceed its own window, or one uninterrupted session hits a wall;
and each
longer one must sit under what the shorter already permits, or it never
binds and
is decoration.
Burn is recorded as segments at one rate, because a run's rate does not
survive
its own lifetime. On our own hardware a bigger tier costs more; on a
caller's own
card it does not, since there is no share of a card of ours being spent.
The gate is at the one moment it may speak — before a run starts, never
again. A
limit refuses the next run and never interrupts one going.
## Payment
Checkout, portal, and a webhook. No price, no currency and no card
detail is
stored: a subscription's existence and its state are the whole of what
crosses
back. Free is a real subscription too, created outright since nothing a
month
needs no payment, so an upgrade changes a subscription rather than
inventing a
customer.
The webhook is the only route no session protects. A signature over the
raw body
stands in for one, checked before the body is parsed, and with no secret
configured it refuses everything.
## Breaking
- `x-nestri-admin-token` is no longer accepted; `ADMIN_SHARED_SECRET` is
no longer read
- `POST /games`, `GET /waitlist` and the `/pairing-code` routes are gone
- `POST /games/sync` and `POST /library/sync` now need host credentials
and take `userId` in the body
- `POST /steam/link` no longer accepts `userId`; `POST
/games/download-state` no longer accepts `hostId`
- `POST /session` responds `{ data, billing }` rather than `{ data }`
## Checks
342 tests pass. Typecheck unchanged from before the branch — the two
pre-existing
errors in `utils/hook.ts` and `utils/validator.ts` are untouched.
Billing is inert until configured: unset `POLAR_*` means every team is
free, no
checkout starts, and the webhook refuses every delivery.
