The provider reuses a customer it already has under the same email and
leaves our team id off it, so the subscription arrived with no team,
was acknowledged, and changed nothing: a paid plan never applied. The
checkout now carries the team in its metadata, which the subscription
keeps, and the webhook reads it there when the customer has none. A
paid delivery that still matches no team is logged instead of dropped
in silence.
(cherry picked from commit 1301ff0806)
A sign-in on a person's own host recorded the enrolment but never
linked the Steam account, so their first launch asked them to link it
again with nothing in the app to do it from. The QR sign-in is the same
proof on their host as on ours.
(cherry picked from commit 24ad9f6b78)
/download/windows and /download/linux redirect to a one-minute signed URL
for the current desktop app, from the same private bucket as the host
agent, so a download page can link to them once and every download still
passes through the API. Which version they hand out is a constant bumped
by a commit after a release is published, as the host installer's is.
/desktop.sh installs it on Linux for the calling user: one binary in
~/.local/bin and a launcher entry, no root.
A host holds only so many runs at once, and until now every waiting run
was handed to it regardless; the ones it could not hold failed there.
The host now says on its heartbeat how many runs it holds, and is handed
only as many waiting runs as it has free. The rest wait in line: paid
runs before free-weekend runs, then first come first served. Reading a
waiting run returns its place in line, and says when a paid run that
asked later has gone ahead, so a free player is never reordered quietly.
A waiting run nobody has asked after for a minute was abandoned, and
leaves the line rather than holding up everyone behind it. A host that
does not report its slots is handed every run, as before.
The desktop app gives a new cloud user a fleet box and then opens that
machine's Steam sign-in on its hostname; GET /box now says which hostname,
and which box is the fleet one.
The codec the clients agree on goes to the encoder over a socket that does
not exist until the game draws, and a client can connect first. The command
was dropped, the encoder started on AV1, and a client without AV1 sat on a
splash with sound and no picture. Commands now wait for the socket, and a
frame in a codec no client decodes sends the agreed set again, which also
covers a launcher handing over to a game with an encoder of its own.
xs is a box with no stream, sm 720p, md 1080p, lg 1440p and xl 4K. Each
resolution keeps its price, so md is now 1x. New boxes default to md, and
existing boxes move up one size so none of them drops a resolution.
POST /session takes an optional tier. The host starts the run at that
size, the allowance is checked against it, and the run is billed at it.
A run asked for without one runs at its box's size, as before.
The size belongs to the run rather than the box: a box is a game's
install on a machine, and the size is chosen each time it is played, so
playing bigger never means a second box and a second install.
Asking for a run on a busy box is refused, but the refusal does not say
what holds the box. A client that just lost its connection needs to know
whether the run in the way is the game it asked for, which it can rejoin,
or another one it should offer to stop. GET /session answers that.
GET /machine/:id/downloads lists every game the machine is downloading,
has ready or failed to download, with progress and each game's name.
The library already carries a download per game, but it is the most
recent one across every host, which is not what a person watching their
own machine set up wants to see.
Owner-scoped in the query: a machine that is not yours answers 404, the
same as one that does not exist.
A host cannot tell a run somebody is playing from one nobody has looked
at in an hour, so it cannot end the second without guessing.
The hub now answers the address socket with a second line,
`viewers <n>`, counting clients that are streaming. Init reads it
alongside the address and sends a new `viewers` message to the host
when the count changes. A reader that takes only the first line gets
the address exactly as before, a server that never writes the second
line is still read, and a host that does not know the message skips it,
so either end can ship first.
POST /session/:id/stop. A run no host has claimed ends at once; one that
is starting or live is marked with time_stop_requested and its host is
handed a session.stop with reason `user` on every poll until it reports
the run ended. The host already ends a run the same way whatever the
reason, so no host change is needed.
Asking twice keeps the first time asked, and asking of a finished run
changes nothing. Somebody else's run answers 404, and a host cannot
stop a run as its owner.
The host report gains gpus: each card's model, VRAM in MiB when the
driver says, and the PCI id it was named by. Kept on the machine (a jsonb
column, written only when it changes) and returned by /machine. What a
person calls the machine, and the first measured part of the capacity a
scheduler will place by.
A sync is the whole of what the account owns, but it only ever upserted,
so a revoked licence or a library from a previous Steam account stayed
listed forever. A sync that fully lands now soft-deletes the rest; an
empty list prunes nothing, and a game owned again comes back.
The report schema pinned each box's tier to our size enum, but hosts name
a box's shape by resolution (1080p). Every report naming a box was a 400,
so stop reasons never reached the run. Placement already stores the size;
the reported label is free text and is not stored.
- **Installer:** piped into `sudo`, installs to `/usr/local/bin`, and
hands onboarding `/var/lib/nestri`. Root lets the host agent jail each
box under its own uid and give guests a network. A host that ran the
agent as the sudo user has that state copied over (never moved), so it
keeps its machine identity and its downloads. Pins host agent 0.2.4.
- **Base image:** `vhost-user-nvgpu` and `nvgpu-userspace`, static
(musl), from the same `NVGPU_REF` as the guest driver and Vulkan layer,
under `/boot/host`. The host agent takes them out at unpack, as it does
the kernel, and forwards the GPU when it finds the NVIDIA driver loaded.
Merge after the host agent 0.2.4 release: the installer pins it.
A QR sign-in on Nestri's own hardware proves the Steam account, so `POST
/machine/enrolment` from a machine in `FLEET_ORGANISATION_ID` also links
it to the person. Hosts somebody brought never link (a machine vouching
for itself could attach any Steam account to anyone enrolled on it). A
Steam account already linked elsewhere stays there; the report is
recorded either way.
Tests: three new in `enrolment.test.ts` (fleet links and is idempotent,
own host does not link, taken account is left alone). 164 pass.
The guest's audio stream ran about 3.5% short of realtime: 193 packets a
second where 200 were due, with no network loss at all. The client plays
at its own 48 kHz, so its buffer drained and underran every few seconds,
idle or loaded.
The graph was running 128-frame (2.67 ms) cycles. The 256 floor for VMs
matched on `cpu.vm.name`, which PipeWire reads from DMI and nesbox does
not provide, so it never applied, and neswire's 240-frame request was
rounded down to a power of two. A busy guest missed ~20 of those cycles a
second (pw-top ERR on neswire), and each missed cycle's audio never
reached neswire while the graph clock moved on.
- PipeWire is fixed at 240 frames, power-of-two rounding off: one cycle,
one 5 ms Opus packet, twice the headroom of before.
- neswire reads the graph position each cycle and fills exactly the
frames a missed cycle skipped, as silence, so the stream stays at
48 kHz whatever the scheduler does.

Each client states what it decodes when it connects, and the hub passed
each statement to the encoder as it arrived. The newest client decided, so
a client that only decodes H.264 lost its picture as soon as one that
decodes AV1 or H.265 joined.
The hub now keeps every client's statement and gives the encoder their
intersection, recomputed when a client joins, when one leaves, and when the
controller returns to automatic. A room settles on the best codec all of
its clients share, and moves up again once the client holding it back has
left. Manual mode still leaves the encoder alone; the change is applied
when the mode goes back to automatic.

POST /steam/link took a Steam id from the request body and linked it. A
Steam id is public, so anyone could claim any account, its library, and
the one free weekend that is keyed on it.
Linking is now POST /steam/link/start, which returns a Steam sign-in URL
tied to a one-time, ten-minute request, and GET /steam/link/callback,
where the browser comes back. The callback accepts the id only if Steam
confirms the assertion, the assertion was issued for exactly this
callback, and the id is read from Steam's claimed identity URL in the
one shape Steam issues it. The request is spent on use.
An install token can now name an organisation instead of a team, and the
host it registers belongs to that organisation's fleet. Only members of
the organisation may mint one, since fleet hardware is rented to other
people. A token for both is refused, by the route and by a check
constraint, as it already is for a machine.
A team with no plan may run on the fleet from Friday 00:00 to Monday
00:00, Helsinki time, for two hours of live play per weekend. One trial
per team, per email address and per Steam account; the claim outlives
the account, so closing it and signing up again is not a second trial.
Once five teams pay, the trial closes for everyone.
A trial run is marked on the session. Its time is counted from the run's
own live interval and kept out of the plan's allowance. Unlike an
allowance, the trial ends a run: the host's work poll now carries a
session.stop job for any trial run past its hours or its window, which
an agent that does not know the kind already skips.
A fleet machine belongs to an organisation, which is not something that
pays, so fleet runs were neither checked nor metered. The payer is now
the box owner's personal team, and the meter that starts and stops with
a run asks the same function the start check does, so the team checked
and the team billed cannot differ.
Fleet machines refused everyone, because nothing could yet say who had
paid for them. A run on one can only exist once it passed the start
check, so a starting or live run of your own box on that machine is now
what grants access, and it ends with the run. Holding a box is not
enough: a box costs nothing to hold.
POST /box places a box once, at creation. On your own host it keeps the
existing rule (exactly one host, or refuse). On the fleet it picks an
online machine owned by the fleet organisation, the one holding the
fewest boxes. Each person holds at most one fleet box. Which organisation
is the fleet is deploy configuration, so no deployment rents hardware it
was not told to.
No machine online is a 429, since the same request succeeds once one is
back.
send_many_datagrams queues a frame's fragments under one lock hold and
one driver wake instead of one per fragment. It also rejects the whole
frame on TooLarge, so a path that shrinks mid-frame no longer leaves half
a frame on the wire for the client to time out. Eviction behaviour is
unchanged. A refused PyroWave frame now keeps its sequence number, since
nothing went out under it. pyro_bench mirrors both ends.

The host can now ask a box for a shell on a pseudo-terminal, the way a container
runtime attaches to a container. `HostToGuest::Attach` starts the process, and
the guest then dials the host on a vsock port of its own (7001) and carries the
terminal's bytes over a small framed stream: data both ways, a resize, a hangup,
and the exit status last. A screenful of output on the JSON-lines control channel
would hold every other message in the box behind it, which is why it is not
there. A failure to start is the exception, and is said on the control channel
because nothing has connected to the data port yet.
A shell is not a launch: it never ends the box, and the box ending ends it. It
is started through the same reaper as everything else, so it cannot become the
zombie that exists to be prevented. With a terminal on the other end the PTY is
ordinary; without one it is put in raw mode so a command run for its output gets
its bytes back unrewritten. Closing the stream hangs the shell up, process group
and all.
The frame codec is a pure bytes-in, frames-out module in nesprotocol with a
payload cap and no skipping of unknown tags, since a length read from a guest is
read across a trust boundary. No version bump: adding a message does not need
one, and a guest that predates it simply never dials.
The runtime stage gains strace, lsof and less, so a root shell in a box is not
one that cannot trace a process.
