feat(machines): update any PC from here, one or all, over relay, direct or SSH - #3309
Every PC added here is now updated from the PC in use. This covers PCs reached through the relay (direct or relayed) and over SSH. Nobody has to go to that PC.
Badge on the roster.Machine.ovis_update is the update a PC can take from here, told unasked:
own: the PC's own Ovis offers a newer release. A connected relay PC or SSH-own-Ovis PC is asked through its connection (GET /api/updates) when it connects and then every 5 minutes.
bridge: this app's bridge on that PC is of another version.
When an update is offered but cannot run from here, updatable: false comes with a plain-words reason.
One per-PC route.POST /api/machines/:id/update (202 { job_id }) works whichever way the PC is reached.
A connected PC's own Ovis is asked to install the release it offers, by revision (no redirect followed). It is followed through its restart and reconnect until it answers on that release (server/pc-update.ts).
Anything else runs the existing bridge update.
When nothing can run, the answer is 409 update_unavailable with the same words.
DELETE ends the wait.
One click for all.POST /api/machines/update-all returns { started, queued, skipped }. Own updates run side by side. Bridge updates run one after another, sharing one bundle download, and show updating.queued until their turn.
Failures in plain words.Machine.update_error keeps why a PC's last update failed. It is cleared when the next one starts.
A relay PC no longer has to be updated on that PC. The relay device this server paired as already drives, and the test shows its install goes through.
Contract: shared/machines.ts (PcUpdateOffer, PcUpdateStarted, PcUpdateAll, MachineUpdate.queued). Docs: docs/remote-pcs.md, "Updating PCs from here". This is the server/contract half; the devices-list buttons come in a separate UI change.
Who may do this (contract change)
One guard covers every change to this PC's PCs, and this PC's own updates: every POST, PATCH and DELETE under /api/machines/ except a PC's own proxied routes (its panes, workspaces and files), plus POST /api/updates/install and POST /api/herdr/update. The rule is ownerAccess (level === "full" && role === "drive" && via not open or portal) and updateRequestAllowed (X-Herdr-Update: 1, same origin, no query). Anything else gets 403 forbidden. The connection server's bridge token still asks for its own install by revision.
May
Who
Yes
a driving sign-in on this PC, its token, its Tailscale login
Yes
a driving device paired with this install, directly or over the relay (the owner's phone, his other PCs)
No
a visitor of an open install, with nothing paired
No
a Portal visitor, whatever role Portal gives
No
any device that only watches
Before this PR, the existing /api/machines changes (setup and approve, settings, enable, remove, update-bridge, relay and Tailscale adds) took any driving caller, the open LAN and Portal included, and /api/updates/install and /api/herdr/update took any authenticated caller with the header. server/machine-owner-guard.test.ts runs every route against every kind of access, with and without the header. The app sends the header on every PC request (machineRequest), and the sidebar's update buttons send the release the card shows.
Validation
bun run check fast: passed (typecheck, build, unit 13009 pass / 0 fail).
New: server/pc-update.test.ts (offer reading, following an install through a restart, failures in its own words), and 3 relay contract tests in server/relay-pc.contract.test.ts (two real servers through a local relay, with a stand-in updater on the far PC). Extended: server/machine-own-update.test.ts (the SSH badge, the one route, refusals and update_error).
Skipped: browser regressions (no UI change); integration and browser CI run on GitHub.
…ct or SSH
Each PC on the roster carries ovis_update: the update it can take from here (its own
Ovis's offered release, read through its connection, or this app's bridge), or why
it cannot. POST /api/machines/:id/update starts it whichever way the PC is reached,
POST /api/machines/update-all starts every one, and update_error keeps why one failed.

Summary
Summary by CodeRabbit
New Features
PCs connected through a relay or SSH can show whether an Ovis update is available and why an update may not be possible.
Start an update for one PC or multiple PCs from this PC. Updates show progress and report failures; queued updates can be cancelled.
Update controls are available to owners.
Documentation
Added guidance on update eligibility, progress, cancellation, and updating individual or multiple PCs.
PCs added through the relay or SSH can now report available Ovis updates and start individual or bulk updates remotely. The server exposes owner-gated routes, tracks offers and update jobs, and reports progress and failures.
Adds update request and result contracts, owner access checks, configurable polling timings, and owner-gated individual and bulk routes. The documentation and tests cover the route behavior and access rules.
Read and follow own-PC updates server/pc-update.ts, server/pc-update.test.ts
Adds authenticated status reads and revision-bound install requests. The helper reports progress and handles restart, cancellation, refusal, and timeout outcomes.
Discover and track PC update offers server/machines.ts, server/machine-own-update.test.ts
MachineManager polls eligible PCs for update offers and revision data. It clears or refreshes offer state as PC connections and machine lifecycles change.
Start, queue, and track PC updates server/machines.ts, server/machine-own-update.test.ts, server/pc-update-all.test.ts, server/relay-pc.contract.test.ts
MachineManager starts individual and bulk updates, queues work, limits concurrent own-Ovis updates, supports cancellation, and records failures. Tests cover relay-PC updates, revision changes, queue behavior, and failures.
devswha/ovis#2829: Adds the relay-paired PC model and tunnel path used by this PR’s relay-PC update flow.
devswha/ovis#2048: Adds an SSH-connected PC’s own-Ovis update flow, which overlaps with this PR’s remote status and install behavior.
Merge Risk: Moderate · previous review d7619
Resolve the legacy update access bypass before merging: non-owner visitors can initiate eligible SSH PC updates. Queue revision binding, cancellation, and concurrency handling also need correction so updates honor the requested release and scheduling limits.

Explanation
The title states the main change: PCs can be updated from the current PC, either one or all, over relay, direct, or SSH connections. The changeset adds per-PC and update-all routes, Machine.ovis_update offers, and relay/SSH update handling, so the title matches the primary change.

It also covers a contract change and access rules, which the template does not require. The Change section does not link an issue, and the template asks for one when a feature is added. The linked objectives reference PR #3309, but the description does not link an issue or state that a maintainer agreed to the feature. The Validation section also lists focused test files and the relay contract tests, which fits the template's request for contract-test coverage on HTTP changes.

…ay why in plain words
An update names the offer's revision and follows only the PC it was asked of: a PC
removed, moved or replaced meanwhile, or another release on offer, is refused rather
than installed. A busy answer from a check for releases is asked again once the check
ends. Offer reads are per connection and start again after a setup moves the PC, and a
PC disabled or removed in herdr drops its update.
Adversarial review (Codex, gpt-6.1-terra xhigh) on e23766a. All findings were fixed in 78e826c:
HIGH, an update could reach another PC after an SSH move. Fixed: the follower is bound to the runtime and to the SSH address it was asked at. A PC that is removed, replaced or moved meanwhile is not asked, and the update ends with plain words.
HIGH, the install was not bound to the offer the person saw. Fixed: the offer carries revision. POST /:id/update takes { revision } and refuses (409) when the PC offers another release. The follower installs only that revision, and update-all uses each PC's last-read revision. Tests: pc-update.test.ts "installs only the release the person was shown", plus the relay contract test.
MEDIUM, update_busy from a running check was followed as if it were an install. Fixed: the status is read again. A running install is followed; after a check, the install is asked for again (3 tries). Test added.
MEDIUM, an offer read from an earlier connection could hold back the current one. Fixed: the in-flight read is scoped to its connection generation.
MEDIUM, a setup that moves the PC to an address running its own Ovis started no watcher. Fixed: the watcher starts again once the move commits.
MEDIUM, disabling or removing a PC in herdr did not drop its own update. Fixed: dropUpdate now runs on profile removal, disable/enable and prune.
LOW, refusals showed protocol codes. Fixed: only the remote's message, or plain words for update_offer_changed.
Validation after the fix: bun run check fast passed (unit 13019 pass / 0 fail). The focused files (machines-refresh, herdr-profile-sync, machine-own-update, pc-update, relay-pc contract) pass 149/149.
…st the queue and cancel
Update all skips a PC whose automatic bridge update already waits, and checks again
at its turn that the update is still needed. A PC still in its queue keeps showing
that it waits. A shown revision is compared only with an offer that names one, and a
relay PC is pointed at Update instead of its own screen.
dori review on 78e826c was BLOCK (2 MEDIUM, 2 LOW). All four are fixed in 8241ae9:
MEDIUM, Update all could repeat a bridge update. Fixed: updateRunning now counts an automatic bridge update already waiting (autoQueued). At its turn, a queued step checks again that the update is still offered and still not running, and does nothing otherwise. A setup that ends no longer clears updating on a PC still waiting in the queue.
MEDIUM, the queue, cancel and drop paths had no tests. Added server/pc-update-all.test.ts, 4 tests:
two bridge updates run one after another, with updating.queued until each one's turn;
an update that is already queued automatically, or already done before its turn, is not repeated;
DELETE on a queued entry, and removing a PC while it waits, never update it;
DELETE on a running own update ends the wait with no update_error.
LOW, RELAY_PC_UPDATES now points at Update (POST /api/machines/:id/update).
LOW, a shown revision is compared only when the offer names one.
Validation: bun run check fast passed (unit 13015 pass / 0 fail). The focused files (pc-update-all, machine-own-update, pc-update, relay-pc contract, herdr-profile-sync, machines-refresh) pass 153/153.
…sal as update_unavailable
A disabled PC offers no update and Update all skips it, so it is never connected
again by an update. A PC from herdr not approved to connect says so instead of a
400. A successful own update clears only the offer it installed.
The second dori review on 8241ae9 was BLOCK (1 MEDIUM, 3 LOW). All four are fixed in 776b16f:
MEDIUM, Update all could turn disabled PCs back on. Fixed: updateOffer returns null for a disabled PC, so it shows no badge, Update all skips it, and POST /:id/update refuses it (409). A test covers it.
LOW, a newer offer could be hidden after an own update. Fixed: the update clears only the offer it installed (offerRevision is still that revision).
LOW, an assertion could not fail. Fixed: it now waits for the queue step to settle before asserting.
LOW, some refusals came back as 400. Fixed: a PC from herdr that is not approved to connect now offers updatable: false with that reason. The route maps MachineActionRequired to 409 update_unavailable too.
Validation: bun run check fast passed (unit 13024 pass / 0 fail). The focused files pass 172/172; conventions passes alone, 19/19.
…me, and only the release shown
POST /api/machines/update-all and /api/machines/:id/update took any driving caller: an
open install's visitor, a Portal visitor or a relay peer could update every PC. They
now take only this PC's owner (ownerAccess), from this app's own page, as the runtime
switch does. Update all runs at most four own updates at once, and an SSH PC's own
Ovis older than this app installs only the release it showed.
The merge pass found a HIGH and two MEDIUMs on 776b16f. All are fixed in d7619bf:
HIGH: only the owner may update PCs. Before this fix, POST /api/machines/update-all and POST|DELETE /api/machines/:id/update checked only readOnly.
Both routes now take only this PC's owner (ownerAccess in server/access.ts: level === "full" && role === "drive" && via not open, portal or relay). The value is computed in dispatch.ts and passed to handleMachineRequest as a new trailing owner parameter, which defaults to false (fail closed).
Both routes also require updateRequestAllowed(request): the X-Herdr-Update: 1 header, the same origin, and no query.
Anything else gets 403 forbidden.
Tests, in server/pc-update-access.test.ts:
per access kind through decideAccess: local, token, paired driving device and Tailscale login are let in; open LAN, watching device, Portal visitor with drive, and relay peer with drive are refused;
each route refuses a non-owner, a request without the header, a query, and a DELETE from a non-owner;
a real createServer on 0.0.0.0 refuses an open-LAN visitor (403) and lets the owner on this PC in (202).
MEDIUM 1: Update all's fan-out is bounded. At most OWN_UPDATES_AT_ONCE (4) own updates run at once. The rest show updating.queued and start as one ends, checked again at their turn. Bridge updates were already serial. Test: six PCs, four start, and the fifth starts as the first ends.
MEDIUM 2: an older SSH PC installs only the shown revision.ownOffer now keeps the offered latest_revision, and an SSH PC's ovis_update.revision carries it. POST /:id/update and Update all pass it through updateBridge and setup to the job. runOwnUpdate refuses with plain words, and installs nothing, when the PC offers another release. The test failed without the check.
The pre-existing point (own-server updates trust Git tags without a signature or sha256) is not touched here, as asked.
Validation: bun run check fast passed (unit 13023 pass / 0 fail). The focused files (pc-update-access, pc-update-all, machine-own-update, pc-update, relay-pc contract, access, herdr-profile-sync, machines-refresh) pass 236/236.
API note for the UI lane: both routes now need X-Herdr-Update: 1 beside X-Herdr-Machine: 1.

Review comments at @docs/remote-pcs.md:
- Around line 177-178: Update the response documentation in remote PCS for a
watching device sending a valid update request: specify that it receives 403
`read_only`, distinguishing this from the 403 `forbidden` response for the
visitor cases described nearby.
Review comments at @server/machine-api.ts:
- Line 352: Apply the owner and update-request authorization enforced by
updateRequestAllowed to every legacy update entry point, including setup
requests that specify update_remote, before allowing an SSH PC’s own-Ovis update
to start. Reuse the existing authorization checks and preserve the forbidden
response for unauthorized requests.
Review comments at @server/machines.ts:
- Around line 834-835: Preserve the requested revision in each entry queued
through queueOwn or queueUpdate, and validate it when the job starts; refuse to
install an offer if its revision changed after queueing.
- Around line 844-847: Update the cancellation flow around runtime.ownJob,
updateQueued, and the pending-job lookup to suppress an automatic bridge update
waiting behind another job, so it cannot start after DELETE
/api/machines/:id/update. Preserve the existing active-job abort and other
queued-update cancellation behavior.
- Line 860: Update queueUpdate and the Update all scheduling path to share the
four-PC concurrency limit for own updates, including disconnected SSH PCs.
Ensure an SSH update waits until a slot is available when four own updates are
already running, using ownRunning or the existing shared scheduling mechanism to
count active own jobs.
Review comments at @server/pc-update.ts:
- Around line 92-96: Check the requested revision against the active
installation before following it in the `installing` flow in `pc-update.ts`,
including after each busy retry refreshes status. If an install is active for a
different revision, refuse to follow it so the requested revision can be handled
instead of timing out.
Review comments at @shared/machines.ts:
- Around line 88-89: Update the documentation for POST /api/machines/:id/update
to clarify that 409 update_unavailable indicates a cached revision mismatch.
Document that if the remote offer changes after the cached offer is read, the
request returns 202 and the job reports the refusal in update_error; add this
asynchronous case to the remote-PC documentation.

…d update keeps its release
update-bridge and a setup with update_remote now take only this PC's owner. Update
all counts an SSH PC's own update against the same four at once, keeps the release
each PC was queued with and refuses another one at its turn, and an install of
another release already running there is not followed. A Cancel also stops an
automatic bridge update still waiting. The docs say when 409 comes and when the
202 job tells the refusal.
…fers only what may run
One PC whose update throws at its start (no setup slot free, a PC not approved) is
told under skipped and the others go on. An SSH PC's own update is offered only where
this app may connect and manage it, as a bridge update is, and a setup slot refusal
answers 409. The relay message and the changelog say it in plain words.
…s, and queued updates keep their own entry
PATCH /api/machines/:id with enabled true (which reconnects it and may update it)
and approving a setup's changes now take only this PC's owner from this app's own
page, as update-bridge and a setup with update_remote now do too; the app sends the
update header on every PC request. update-bridge binds the release the card shows.
A PC cancelled and queued again runs on its new entry, not the stale one.
Two commits answer the dori review on 2752b01 (BLOCK: 1 MEDIUM, 3 LOW) and the merge pass's two HIGHs and two MEDIUMs. Each fix has a failing-first test.
MEDIUM: Update all now puts a PC whose start throws (no setup slot free, a herdr PC that is not approved) in skipped with its words, and goes on to the rest. An SSH PC's own update is offered only where this app may connect and manage it, as a bridge update is. A setup-slot refusal on an update answers 409. Tests cover the job cap and an unapproved PC.
LOW: the relay PC message is now in plain words, and the changelog says this is the server half.
LOW, a UI follow-up: the bridge-update action shown to a non-owner. The app now sends the update header; hiding the button for non-owners comes with the UI change.
HIGH 1: PATCH /api/machines/:id with { enabled: true } reconnects a PC, and with automatic bridge updates on that may update it. It is now owner-only, from this app's own page.
HIGH 2: POST /api/machines/setup/:id with { action: "approve" } is now owner-only in the same way. Answering or cancelling a setup, and renaming or turning off a PC, stay a driving device's.
update-bridge and a setup with update_remote now also need the update header. machineRequest in src/lib/api.ts sends X-Herdr-Update: 1 on every PC request, so the app keeps working. Tests: each route refuses a non-owner and a request without the header, and lets the owner through. A real server on 0.0.0.0 refuses an open-LAN visitor's enabled: true and approve.
MEDIUM 1: update-bridge binds the release the card shows: the body's { revision }, or else the offer the PC's last connect read. Test added.
MEDIUM 2: queue entries are now keyed by a token per entry. A PC cancelled and queued again runs on its new entry, and the stale one neither asks nor tells. Test added.
Older tests and the SSH/Windows QA scripts that call these routes send the header too.
Validation: bun run check fast passed (unit 13034 pass / 0 fail). The focused files, including herdr-profiles contract, machine-update and the client tests that use machineRequest, pass 362/362.
…his app, a setup slot kept free
Changing what runs on these PCs is the owner's from any device he signed in or paired
himself, relay-paired phones and his other PCs included; open-LAN visitors with
nothing paired, Portal visitors and watching devices are refused. An SSH PC's own
update to a release newer than this app is offered as not possible here, SSH own
updates through setup leave one of the four setup slots free, and turning automatic
PC updates on takes the same owner rule.
…ts own updates
Every POST, PATCH and DELETE under /api/machines/ but a PC's own proxied routes now
takes one rule, as do POST /api/updates/install and /api/herdr/update: the owner from
any device he signed in or paired himself (relay included), from this app's own page;
never an open-LAN visitor, a Portal visitor or a watching device. One table test runs
every such route against every kind of access. The sidebar's update-bridge buttons
send the release the card shows.
This round follows the merge pass's final approach, in 2edf3c2 on top of bd505a0:
One guard. Every POST, PATCH and DELETE under /api/machines/ (setup, setup answer, approve and cancel, settings, rename, enable and disable, remove, update, update-all, update-bridge, relay, relay/code, tailnet) uses the owner rule plus updateRequestAllowed. A PC's own proxied routes are left as they were. POST /api/updates/install and POST /api/herdr/update take the same rule, except the bridge token's own install by revision.
One table test, server/machine-owner-guard.test.ts: nine kinds of access against 14 routes, each with and without the header. It failed on every row before the guard. A real server on loopback refuses an open-LAN visitor on /api/updates/install and /api/herdr/update, and lets the owner on this PC through.
The older SSH-PC button. The sidebar's two update-bridge buttons send { revision }, taken from ovis_update.revision.
Earlier commit bd505a0. This holds the owner rule, so a driving device paired over the relay is allowed. It also refuses an SSH own update to a release newer than this app; that PC would come back with a newer bundle this app refuses, cut off from here. And own updates through setup leave one of the four setup slots free.
Tests. Older tests and QA scripts that post to these routes as the owner now send the header.
Validation: bun run check fast passed on old-desktop (unit 13050 pass / 0 fail). Each machine-route test file passes alone. Four conversation-API tests time out at 10 s on this loaded host (load 147); they time out the same way on origin/main, so this change did not cause them.
…e past this app, no real SSH in the guard test
POST /api/updates/check installs where OVIS_AUTO_UPDATE=1, so it takes the owner guard
too. update-bridge refuses an SSH PC's own Ovis on a release newer than this app, as
its card does. The guard's table test stubs SSH, so the owner's setup row reaches no
real PC.
Last small push, 8908adf, as the merge pass asked. Each change was tested failing first:
HIGH: POST /api/updates/check now goes through the owner guard. Where OVIS_AUTO_UPDATE=1, a check installs. It joins the guard's real-server rows: an open-LAN visitor gets 403, the owner on this PC is let through.
MEDIUM: update-bridge now refuses an SSH PC's own Ovis on a release newer than this app, as the card does (NEWER_THAN_APP). Test added. The sidebar's update buttons send ovis_update.revision for a disconnected PC too; with no revision, the server uses the release the card shows (remoteRevision).
The guard's table test now stubs SshConnection.prototype.start, so the owner's setup row reaches no real PC.
Validation: bun run check fast passed (unit 13051 pass / 0 fail).
…a release it cannot tell
A PC's updater on the beta channel offers versions such as 0.6.0-beta.2, which were read
as no version and passed the newer-than-this-app check. Betas are now read and compared
(a beta comes before its release), and an offered update whose version cannot be told is
refused from here, on its card, in Update all and in update-bridge.
An adversarial review of #3313 (Codex CLI, gpt-6.1-terra, xhigh, service_tier fast) found a HIGH that also applies here. It ran through the team proxy because the owner's Codex login had hit its usage limit.
HIGH: a beta release passed the "newer than this app" check. A PC whose updater is on the beta channel offers versions such as 0.6.0-beta.2. releaseVersion read those as no version, and newerThanThisApp(null) let them through. An SSH PC could then be updated past this app, which would refuse to connect to it afterwards.
Betas are read, in releaseVersion in both machines.ts and pc-update.ts.
Versions are compared in order, and a beta comes before its release: 0.6.0-beta.2 is newer than 0.5.1 and older than 0.6.0.
An update on offer whose version cannot be told is refused from here, with plain words.
The same check (pastThisApp) applies on the card, in Update all and in update-bridge.
docs/remote-pcs.md says so.
Test: pc-update-all.test.ts "reads a beta release as its updater offers it, and refuses one newer than this app, or one it cannot tell". It failed before the fix.
Validation: bun run check fast passed (unit 13052 pass / 0 fail).
Merged on GitHub's required checks, all green on this head (Fast checks, Integration and browser, Native Windows install).
omo review receipt: CLEAR at this exact head. Unresolved review threads: 0 (GraphQL). CodeRabbit: skipped; no CodeRabbit review ran on this head.
Update any PC from here, one or all, over relay, direct or SSH. Every mutating /api/machines/* route, /api/updates/install, /api/updates/check and /api/herdr/update sit behind ONE owner guard (full access, driving, not an open-LAN window, same-origin update header), with a table test over every access kind and route; update-all runs four at a time; a PC installs only the release it showed; a release newer than this app (a beta included) or one whose version can't be read is refused. The merge pass's strict reviews over five rounds reproduced and saw fixed every non-owner path to an update (routes, PATCH re-enable, setup re-enable, job approve, auto-update setting, release check). Codex was unavailable for the last delta (usage limits on both routes), Fable stand-in: the beta guard was read in full by the merge pass and is fail-closed. MEDIUM, recorded: the older SSH-PC button can still send no displayed revision for a disconnected PC. LOW: a watch device's proxy read can bring a pending automatic bridge update forward.
…m here (#3313)
## What
**API only for now:** the server routes and the `ovis_update` contract
ship here; the PC card's install action (showing `steps`, start and
cancel) comes in a later release, and the changelog says so.
Builds on #3309 (update any PC from here), now merged; based on main.
This PR adds the case that self-update refuses: a PC reached over SSH
whose own Ovis cannot update itself, or that has no Ovis yet. It is put
right from the PC in use, so nobody has to go to that PC.
- **Started by hand** (`bun run server`, not its updater): the PC's
`ovis_update` becomes `how: "install"`, and its `steps` say in plain
words what will happen. Ovis then does this:
1. Stops that very server, after checking that its pid still runs an
Ovis server.
2. Runs the official installer of this app's release
(`https://raw.githubusercontent.com/devswha/ovis/<tag>/install.sh`, the
script `https://ovis.sh/install.sh` serves), pinned with `OVIS_REF` and
`OVIS_RUNTIME=herdr`, so Ovis is installed as a herdr plugin under its
updater.
3. Starts herdr headless if it is not running, which starts the plugin.
4. Waits for the new server to register (known by its new token), then
connects the PC.
If an Ovis is already installed there (a plugin or its user service),
Ovis starts it that way and updates it instead, because the installer
would keep the release it has.
- **Supervisor too old to install by revision:** Ovis restarts it
through its own launcher (the plugin's stop and start actions, or the
user service), then asks for the update. Without a launcher, nothing is
stopped.
- **No Ovis yet:** `POST /api/machines/install` with an SSH address
installs Ovis and adds the PC. It is refused when Ovis or this app's
bridge already runs there.
- SSH uses keys only (BatchMode) throughout, including the final
connect. Every failure carries an `error_code` and plain words (no ssh
access, unknown host key, unreachable, unsupported OS, missing
curl/git/tar, under 1 GB free, home not writable, the installer's own
last words, not started, ...). A named herdr session is refused. The
desktop app's own server is never replaced.
- One job at a time per PC: a setup or install for the same address is
refused while an install runs. Cancelling also cancels the connect it
handed over to.
Contract: `shared/machines.ts` (`PcUpdateOffer.how: "install"` and
`steps`, `PcInstallRequest`, `PcInstallJob`, `PcInstallFailure`).
Routes: `POST /api/machines/install`, `GET/DELETE
/api/machines/install/:id`. Docs: docs/remote-pcs.md, "Installing Ovis
on a PC over SSH".
Known limit: like a run by hand, the installer installs what is missing
for that account (herdr, Bun, which may add itself to a shell startup
file) and runs `tailscale serve` when Tailscale runs there. The steps
shown before the install say so. A release before 0.4.13 cannot be
updated this way.
## Validation
- `bun run check fast`: passed on the final commit (unit 13048 pass / 0
fail).
- Unit: `server/pc-install.test.ts`, 23 tests on a script-answering SSH
stand-in: every refusal, the pinned command line, replace, restart, an
existing install, pid reuse, a changed pid not signalled, cancel
propagation. `server/machine-own-update.test.ts` now covers the install
offer and its 202, and the refusals without one.
- Focused: pc-install, pc-update-all, machine-own-update, pc-update,
relay-pc contract: 108 pass, 0 fail (with herdr-profile-sync,
machines-refresh and conventions: 196/196 before the last rebase).
- Real end-to-end QA in a throwaway Ubuntu 24.04 container with sshd
(keys only, no password) through this app's own API, on the final
commit:
- a key that is not let in gets `ssh_refused` in plain words;
- `POST /api/machines/install` ran the real official installer at
v0.5.1, Ovis came up as a herdr plugin, and the PC was connected (herdr
0.9.5, terminal attach) in 28 s;
- a second install there was refused with plain words.
- Codex (gpt-6.1-terra xhigh) adversarial review: findings and their
resolution are in a comment.
## Behaviour changes beyond the install
- **One setup at a time per PC over SSH**, keyed on the address `ssh -G`
resolves (`user@hostname:port`), for any herdr session and any PC saved
at that address. A second setup there is refused until the first ends,
and Update all reports it as skipped with that reason. An alias, or the
default port given, is the same PC.
- **Cancel** stops an automatic bridge update that is already running,
not only one still waiting its turn.
- **`updateBridge`** (and the legacy update-bridge route) is refused
while the PC's own Ovis updates itself.
- **A just-started updater** that has not checked for releases yet (and
whose check did not fail) is waited for, through the existing check
wait, instead of being read as offering nothing.
