Josh Siviour 208a108c27 fix(ec2): render image CreationDate as UTC (#1057)
An AMI imported on a node whose timezone is not UTC was stamped with local wall-clock time carrying a Z suffix, so on a +1000 node an 11:42Z import reported 21:42Z — ten hours in the future. The layout "2006-01-02T15:04:05.000Z" treats the trailing Z as a literal character rather than a zone directive, so Format printed whatever zone the value carried and then asserted UTC regardless.

DescribeImages now converts before formatting, which also corrects records already stored, since the stored time.Time still carries its original zone. The four sites that stamp a new image now store time.Now().UTC() as well, so the value is right on both sides of the round trip.

Terraform's most_recent sorts on this field, so before this an AMI imported on a +1000 node outranked a genuinely newer one imported on a UTC node for ten hours.

Closes mulga-il7w1.

Josh Siviour ca5ff7695e fix(ecs-agent): allocate a console for a pseudoTerminal container (#1054)
oci.WithTTY put Terminal in the OCI spec while the task was created with a cio
creator that asked for no terminal, so the shim made no console socket and runc
refused to start the container at all. The terminal flag now reaches the FIFO
set, and a terminal carries no separate stderr stream.

Josh Siviour 1ab61b0dd5 fix(ecs): enforce or refuse container runtime fields (TFC-0040) (#1053)
* fix(ecs): enforce or refuse container runtime fields (TFC-0040)

user, mountPoints, volumesFrom, readonlyRootFilesystem, privileged,
pseudoTerminal, interactive, linuxParameters, systemControls,
startTimeout and stopTimeout registered successfully but were never
stored, sent to the agent, enforced, or echoed back on describe.

Store and echo the fields the agent can enforce (user, readonly root
filesystem, privileged, pseudo terminal, interactive, systemControls,
capability add/drop, start/stop timeout), apply them through containerd
via OCI spec options and a graceful Stop, and refuse at
RegisterTaskDefinition the fields the agent cannot honor (mountPoints,
volumesFrom, linuxParameters.devices/initProcessEnabled/
sharedMemorySize/tmpfs). Refusal only triggers on a value that asks
for the restriction; empty lists and false/unset flags are accepted
and echoed as before.

* test: move the bus wire-contract test to an external package

* fix(ecs-agent): release an interactive container's stdin so its copier exits

* fix(ecs): return a caller-supplied empty collection instead of omitting it

Julian Sommer c8d42ac160 docs: publish S3 API coverage
S3 was the one served surface with no coverage page. The gateway has no
operation-name dispatch table for it, so there was nothing to compare against
the model.

Predastore now declares the operations each of its S3 routes answers, so the
generator compares that inventory the same way it compares the other nine
services. The page credits Predastore rather than Spinifex, and its intro
separates what is routed from what conforms, pointing at the ceph/s3-tests
report for the second.

Ben Duncan fea03a5b22 feat: verify JetStream replicas agree after formation, discard stores by default (#1031)
spx admin init now discards the node's pre-formation JetStream store by default for --nodes >= 2; --discard-jetstream=false restores the refusal. spx admin kv digest gains --json with stream replica, retention and limit settings and per-sequence subject, time and TTL. The new spx admin kv compare reads every node's digest and fails only on real divergence: different content at one sequence, a missing message nothing explains, or wrong replica placement. install-node.sh gates formation on it and gains --ipsec on|off, verified on every node. The multi-node guide documents both.

Ben Duncan 455c97a2e7 fix: prod review of 14 September — IPsec follower reads, stopped-instance EIP probes, audit client IP and JetStream formation divergence (#1029)
* fix: read NB_Global.ipsec through the NB remote list so followers and compute nodes answer quietly

* fix: stop probing and nudging the EIP datapath of a stopped instance's port

* fix: log the real client IP, request ID and duration_ms in the awsgw access line

* test: mark the UI proxy header test as in-package

* fix: discard pre-formation JetStream data when forming a multi-node cluster

A node that ran as its own single-node cluster carries KV streams into
formation. nats-server adopts a local stream with the same name as the
clustered one, and raft catch-up only fetches sequences beyond a
follower's last, so the conflicting prefix is never repaired and replicas
diverge permanently.

- spx admin join removes the local JetStream store once formation
  succeeds. A store holding streams now needs --force, and the
  identity-discard warning names it.
- spx admin init --nodes >= 2 refuses a store that holds streams unless
  --discard-jetstream is given, and removes it once every node has joined.
  Keeping it as the seed is unsafe: stream leadership ignores who holds
  data, and unassigned local streams are deleted as orphans.
- Neither removes a store while `spx service nats` runs, --force included.
- install-node.sh passes --discard-jetstream and waits for every
  `spx service` process to exit before formation.

* feat: add spx admin kv digest for per-replica JetStream consistency checks

Replicas of a stream can hold different content while raft reports them
current, and nothing in the cluster detects it. A direct get over NATS is
no way to inspect one replica: a client's request goes to a random member
of the direct-get queue group, routed replicas included.

kv digest copies this node's $G streams tree (without consumer state) to a
temporary directory, opens the copy in a private in-process server with no
listener, and prints first/last sequence, message count and a SHA-256 over
every stored message per stream. Running it on each node and diffing the
output shows which streams diverge; --seqs locates the first differing
sequence. The live store is only ever read.

* fix: let spx admin kv digest read replicated streams

A replicated stream's meta.inf carries num_replicas > 1, which a standalone
server refuses to recover, so the digest could not read any production store.
Rewrite the copy's config to one replica with no expiry and a recomputed
checksum, and test it against a three-node cluster and an expired bucket.

* test: use assert.ErrorIs for the removed JetStream store

* test: mark the JetStream store and digest tests as in-package

* fix: stop the process-group test misreading a reaped child as alive

The test polled until the child was gone, then checked once more. A task
being reaped shows state X for an instant, which processRunning counted as
running, so that second look failed about 1 run in 50 under -race.

* fix: wait for the recovery retry loop before removing a test's data dir

restoreInstances starts the retry loop untracked, and it rewrites the local
state file when it ends. A write landing during t.TempDir cleanup failed
TestRestoreInstances_* with RemoveAll: directory not empty.

Josh Siviour 97d8e4f119 feat: let a node put every volume's WAL on its own device (#1010)
A WAL fsync shares the device queue with predastore, the chunk cache and
every other volume on the node. Measured on the e2e stack, competing
filesystem traffic alone moves fsync p99 from 4.7ms to 22ms with no
change to viperblock, which is the tail an etcd guest reports as its
commit latency.

wal_base_dir under [nodes.<n>.viperblock] routes the WAL elsewhere. It
reaches both the short-lived VBs the service opens and, through the
nbdkit argv, the plugin backing each mounted volume. Unset keeps the WAL
under base_dir.

Ben Duncan 18853cef31 fix: close the four defects keeping the e2e nightly red (#1007)
* fix: stop the e2e analyser inventing failures and let a detach outlast its seal

go-junit-report emits <error message="No test result found"> for a === RUN with
no matching result line, and attaches the test's own captured log as the body.
The analyser counted those as failures, so the baremetal cell reported 25
failures against a junit file recording 1, with log output reading as
assertions. Separate the marker from a real error in both the parse and the
roll-up, count the unresolved cases and say so in the summary.

The gateway gave a detach 30s while the daemon budgets 180s for the ebs.unmount
seal and 180s more for the QMP unplug chain, so any detach whose seal replayed a
WAL was reported as ServerInternal while it went on to succeed.

Also switch four nightly job gates from always() to !cancelled(): always()
overrides cancellation, so a cancelled run kept starting jobs.

* fix: serialise the e2e workflows on one group and retry a dropped libvirt

e2e.yml had no concurrency block at all, so every push to dev could provision
alongside every other push and alongside the nightly. All four workflows that
build on these hypervisors now share e2e-hypervisors, queued rather than
cancelled. A per-environment group is not expressible: GitHub picks the group
before it picks a runner, and the environment is a property of the runner.

tofu apply also failed outright on a transient libvirt connect, which fails a
45-minute job in 90 seconds and reports it as a test failure. retry_run retries
only when that attempt's own output names a connection failure, so a real
failure still fails once.

Also collect the unfiltered journal from the matrix cells and the node journal
from cell-21: the unit filter drops the kernel and OOM lines that explain why
one node behaved unlike its siblings, and a passing run's journal is what makes
a failing one readable.

* fix: build the baremetal junit from the unfiltered suite log

run-baremetal-e2e.sh streams the full suite output to suite-output.log and a
grep-filtered summary to its stdout, which the workflow tees into
test-baremetal.log. That filter anchors --- PASS at column 0 and Go indents
every subtest result by four spaces, so the junit was generated from a log with
no subtest results in it: go-junit-report saw each === RUN with no outcome and
emitted <error message="No test result found">.

17 of cell-28's 39 testcases and 93 of cell-20's 120 were that. Regenerating
cell-28 from suite-output.log gives 39 tests, 0 failures, 0 errors.

* fix: converge released EIPs instead of trusting a fire-and-forget teardown

A disassociate leaves the ENI running, so the orphan sweep's owning-port test
never fires for it. The teardown then rests entirely on vpc.delete-nat, which is
core NATS and is lost whenever vpcd is restarting — and the intent KV watch is
UpdatesOnly, so the same window hides the write that would have driven a repair
pass. The dnat_and_snat row and its host /32 route to a released public address
survived until something else happened to touch them, which for a live ENI was
nothing at all.

Give the sweep the second test it was missing: AddEIP is the only writer of
dnat_and_snat, so the floating IPs intent asks for are the complete set of
addresses that may hold one, and a row for any other address is stale however
alive its port. Ports and external IPs travel together in LiveEIPs, both unioned
from the start-of-pass snapshot and the fresh re-read, so a mid-pass launch is
still spared. The host unbind now runs even when the row had already gone, which
is the state a crash between the OVN delete and the unbind leaves.

Run that sweep on the startup pass too. Startup is the pass that follows the
blind window, so skipping it deferred repair of exactly the changes that were
missed. The port-group and ENI-port sweeps stay gated there for the in-flight
create they were written for; the EIP sweep re-reads intent immediately before
deciding and abandons the whole sweep if that read fails, which is the same
protection by a stronger route.

* fix: keep a release verify off the hypervisors an e2e run is using

release.yml is the fifth workflow that provisions on the ci-single pool and had
no concurrency block at all, so a tag push could land a tofu apply on the same
libvirt host a nightly cell was mid-provision on. The group goes on the verify
job rather than the workflow: the build jobs touch no hypervisor and should not
queue behind a nightly.

* fix: stop cell-27 handing a 50-minute suite a 50-minute job

The rds suite is budgeted 50m in suite-sets.sh and cell-27 took the matrix
default of 50 minutes for the whole job, so provisioning, install, the suite and
teardown had to fit inside the suite's allowance alone. It never could: the last
measured run spent 6 minutes reaching the suite and was killed 44 minutes into
it, mid-TestAutomatedBackups. A job timeout reports "The operation was canceled"
and nothing else, which is why this cell has no verdict in any nightly rather
than a failure anyone could read.

cell-27 gets 75 minutes, and the select job now refuses to start a run whose job
budget does not clear its suite budget plus a setup allowance. The inner timeout
firing first is the property that matters: go test says where it stopped and
what failed, and the job timeout says nothing at all. cell-29 already had the
same fix applied by hand; nothing stopped the next suite from repeating it.

* fix: converge host EIP plumbing against intent, not against the NAT row

The released-EIP sweep landed and did not fire. Its premise was that a stranded
dnat_and_snat row is what a stranded host route can be found by, and on the path
that actually strands one there is no row left. AddEIP scrubs the predecessor
row sharing the private IP before installing the new one, so when reconcile
re-added the instance's auto-assigned address it silently deleted the released
EIP's row — and applyEIPs runs ahead of the sweep, which then walked a table
with nothing stale in it while the /32 route and its proxy-ARP stayed up.

Give the sweep the host's own inventory. ListEIPIngress reads the EIPs back from
the FORWARD accepts EnsureEIPIngress stamps with its own comment, so a binding is
found by what installed it rather than by a row some other path is free to
delete. Anything plumbed that intent no longer asks for is torn down, which also
covers a crash between the OVN delete and the unbind. A failed inventory fails
the pass: an empty list and an unreadable one are indistinguishable, and reading
the second as the first is a sweep that reports success having done nothing.

Close the window inside the pass too. The predecessor scrub now reads the row it
is about to drop and releases that address's host state, so the strand does not
exist between applyEIPs and the sweep rather than merely being repaired a step
later.

* fix: retry the release verify's libvirt calls like every other job does

The verify job drives the same libvirt provider on the same hypervisors as the
e2e cells, where a dropped connection under concurrent load is the steady state
and is retried. Here it was a hard failure that reads as a broken release. It
was skipped earlier only because the job checks out mulga and not spinifex, so
the shared helpers were not on disk — a sparse checkout of .github/scripts costs
nothing and makes apply and destroy behave like their e2e counterparts.

* fix: do not report a rebooting DB instance available on the pre-reboot agent's health

RegisterDBInstance stamped a fresh LastSeen while leaving Agent.EngineHealth at
the value the previous agent process reported. After a reboot the new agent
registers before it has probed anything, so the record read as a healthy engine
with a beat newer than the transition, and the reconciler moved the instance to
available while PostgreSQL was still starting up. A client that connects the
moment the status turns green then gets "the database system is starting up".

A register now discards the previous process's verdict and records when this
agent process started. The restart reconciler requires that registration to be
newer than the transition, which also closes the window where a beat lands
between the engine being stopped and the VM going down.

* test: record the credential kubectl sent when an EKS call comes back Unauthorized

The IRSA pod subtest's first kubectl is the gateway-CA configmap, which lands
before the pod dumps are registered, so a 401 there left no evidence at all. A
verbose read-only probe reports whether an Authorization header was sent, which
separates a token the apiserver rejected from one the exec plugin never made.

* fix: report a starting engine promptly, and budget CI jobs from the suite

The agent waited a full heartbeat interval before its first beat, so a restart
could not be observed as finished for up to 30 seconds after the engine was
already serving. Beat at startup instead, and report every 5 seconds until the
engine has answered once — the control plane is actively waiting on that beat,
and the steady-state cadence it hands back is for a database already serving.

The rds suite is the one most sensitive to what else the hypervisor is doing:
its DB VMs serialise behind a 4 GiB semaphore, so its wall clock is set by how
long it waits for the budget. The same pass ran 45m beside four nightly cells
and overran 50m beside nine, panicking with two tests still running. Raise its
budget to 60m.

That budget was then larger than the jobs meant to contain it. A job cancelled
on timeout reports only "The operation was canceled" and takes the artifacts
with it, so the inner `go test` timeout must always fire first — and it could
not for rds on e2e.yml, nor for storagefault or diskperf, which have asked for
90m and 180m inside a 60m job since they were added. Both workflows now resolve
their job budget from suite-sets.sh rather than carrying a literal: e2e.yml
from the largest requested suite, e2e-suites.yml per matrix leg, so a leg is
bounded by its own suite and not by the longest one beside it. The default push
set resolves to exactly the timeouts both workflows had before.

* fix: check a permutation cell's job budget against the suites it runs

The guard only saw cells that name a suite, so the nine that run a topology's
nightly subset were never checked against it — the same class of mistake the
guard exists to catch, in the majority of the cells. Bound each by the longest
suite in its subset: max() and not sum(), because whichever suite hangs must
panic on its own timeout first, and a sum would demand a budget the set has
never come close to using. Every cell clears it today.

* fix: report why a PostgreSQL engine would not start, and stop failing a stop that landed

Three defects, all found by the first rds pass that ever ran deep enough to
reach them.

A wait that saw an instance reach `failed` called t.Fatalf from inside the
polling condition, and testify runs that condition on its own goroutine. The
Goexit killed the tick and left the collector empty, which reads as the
condition being satisfied — so the wait returned successfully on an instance it
had just declared broken, logged "reached status available" about one that was
failed, and let the test carry on against it. Six conditions across four suites
call Fatal or require the same way. EventuallyErr now runs its condition on the
test's goroutine, which makes all six behave as written.

A DB VM stop has two drivers: the API call and the reconciler resuming one whose
caller it assumes has died. When they overlap the loser is told the VM is not in
a state to be stopped — which is the state the stop was heading for — and the
customer's StopDBInstance returned InvalidDBInstanceState for a stop that had
just completed. Both paths now treat a refused command the way they already
treat an unanswered one: it says nothing about the VM, so the fleet view
settles it.

PostgreSQL had no equivalent of the engine log tail MariaDB has carried since it
was added, so a postmaster that refuses a setting produced "engine did not
respond on /run/postgresql:5432" and nothing else — on a guest with no SSH,
whose console records only that pg_ctl could not start the server. The probe now
quotes the tail of the log the image already directs the postmaster to, and the
reboot and modify paths carry the agent's reason into the failure the way the
create path always has. The reason reaches the customer through StatusInfos.

The rds suite's budget goes to 90m and cell-27's job to 100m. Its wall clock is
what the DB-VM queue costs rather than what the tests do — single tests logged
11m, 22m and 26m waiting for budget — and the pass above still had three of
seventeen tests running at 60m.

* fix: keep a DB VM recoverable when its agent cannot start, and flush the volume before a snapshot

An rds-agent that failed to construct exited, so a transient IMDS credential
resolution took the guest down for good: rds-datadir and rds-init cascade on the
missing handoff, the engine never starts, and the control plane sees only silence
until it declares the instance failed ten minutes later. Construction is retried
like every other boot step instead.

OpenRC skips start_post when the start itself fails, which is the one case with
no diagnostic at all — the console carried nothing but "died". The log mirror
moves out of the handoff wait so a failed start uses it too.

A snapshot quiesced the engine and nothing else. The engine repairs its own files
from the WAL, but postgresql.conf sits beside them and it does not: a restore
came up on a torn tail and the postmaster stopped on a syntax error at the
unterminated include hook. The quiesce now flushes the whole data mount, and the
hook is renamed into place rather than appended, so a boot that finds a half
written one replaces it instead of appending after its open quote.

* fix: flush the config cloud-init wrote before a reset can take it

A DB instance rebooted seconds after it went available came back with no
RDS_GATEWAY_URL, so rds-agent could not reach the control plane and the engine
never started. cloud-init writes agent.env once, per-instance, and never again;
a reboot is a QMP system_reset with no guest shutdown, so the file was still
dirty page cache when the machine reset under it and the next boot read nothing.
The handoff wait now syncs, which is the point at which the agent has proved it
read that file.

* fix: stop dropping an EIP teardown published while vpcd is restarting

DisassociateAddress publishes vpc.delete-nat fire-and-forget. On run
34046316024 vpcd disconnected from NATS at 03:51:26.73 and its replacement
subscribed at 03:51:27.09; the publish landed at 03:51:26.92, in the gap, and
went nowhere. ReleaseAddress then returned the address to the pool two minutes
later with its /32 host route still delivering to the guest that had held it.

vpc.delete-nat now uses request-reply like vpc.add-nat, and retries only on
no-responders — which returns immediately, so the cost is paid solely when
nothing is listening. A teardown that still fails is logged as an error naming
the address rather than lost silently. Neither is fatal to the caller: the
reconciler's orphan sweep remains the backstop.

vpc.add-nat on the EIP path stays fire-and-forget. The shared helper blocks it
on the flows barrier for up to 45s, and associating an address should not
inherit that.

Two reconcile passes in that run had the address absent from intent and did not
sweep its host route, and the journal cannot say why: the sweep logged only when
it acted, so a route it kept was indistinguishable from one it never saw. It now
logs the bindings it found, kept and wanted.

* ci: render one run-level table for the e2e nightly

Reading a nightly meant opening nineteen jobs, and the Actions UI does not
separate a cell that failed from one cancelled out from under it — a
distinction every investigation of this suite has needed, and one the run
34046316024 analysis had to reach for the jobs API to get.

A final job, needs: every cell and if: always(), renders cell, topology,
result, duration, runner and per-cell test counts into the step summary, with
run-level totals, the three slowest cells and the failing test names.

Result, duration and runner come from the jobs API so a cell that died before
writing junit still gets a row. Counts come from a new junit-only artifact per
cell rather than the full cell artifact, so the roll-up does not pull nineteen
journals it has no use for.

Verified against run 34046316024: 14 success, 2 cancelled, 1 failure, with the
two cancellations shown as cancelled rather than folded into failure.

* fix: assert EC2's actual EIP semantics, and probe EKS auth on an authenticated path

natuplink asserted that an instance's auto-assigned public IP is still plumbed
after an EIP associated to the same instance is torn down. EC2 does the
opposite: associating an EIP releases the auto-assigned address back into the
pool, and it cannot be reused. Our datapath already does that — run 34059879666
shows 192.168.0.72's ingress removed at 07:09:44.000, 36ms before .73's was
installed — so the test was asserting behaviour neither AWS nor we have.

It now asserts the release at the point it happens, and that no public delivery
remains after the teardown. This surfaced only once the teardown itself started
working: the run's other assertions passed, including .73's removal, which was
the failure before.

Our records still disagree with our datapath — the ENI keeps the released
address, which is why termination tears the old one down twice and never the
current one. That is the remaining half of mulga-7zc9w and is not fixed here;
it needs an IPAM release on the associate path.

Separately, AuthDiagnostics read /version, which is anonymously readable, so its
200 was consistent with both branches it claimed to distinguish. It now runs
auth whoami, reads kube-system, and invokes the credential plugin directly,
reporting exit code, stderr and whether a token was produced — never the token,
since CI logs outlive it.

* test: capture per-guest state when a spread guest never answers SSH

TestMultinodeSpread's only failure dump is dumpPlacementNATDiag, which collects
OVN, OVS, ARP and route state aimed at the NAT and EIP half of the test. The
failure it actually hits is a guest that never accepted SSH — run 34040324968,
the guest on node3 at 10.100.2.5 — and for that it recorded no console, no port
binding and no tap state. There was no way to tell from the artifact whether the
guest booted at all.

Now dumps, per guest: the console, the NB logical switch port, the SB port
binding, the OVS interface backing its tap, and br-int's port list. Probed on
every node rather than the expected one, because a port bound on the wrong
chassis is exactly what a hosting-node-only dump cannot show.

Covers all three guests, not just the failing one, so a working guest is
available as the control.

* ci: sample hypervisor load either side of every cell

Eight runner names map onto three hypervisors, so cells that never share a
runner still share a host: when cell 10's SSH wait expired on run 34040324968,
cells 22, 17, 18 and 28 were concurrently live, two of them multi-node. Nothing
in the artifacts measured host load, which left co-tenancy as an explanation
that could be neither confirmed nor ruled out.

Records loadavg, MemAvailable, SwapFree, the cpu line carrying steal, and the
QEMU process count before and after each cell, into the cell artifact.

* ci: note that main's missing concurrency block is why the nightly runs ungrouped

Three refs carry three different groupings: main has no concurrency block at
all, dev uses e2e-nightly, this branch uses e2e-hypervisors. Scheduled runs load
the workflow from the default branch, so every cron nightly runs ungrouped and
cannot queue against anything — which is how a dispatch of 34050630627 ran
alongside the scheduled 34046316024 and cost it cells 24 and 27.

e2e-hypervisors is the right group and deliberately broader than dev's, since
e2e.yml, e2e-suites.yml and e2e-ddil.yml draw on the same runner pools. Nothing
on a feature branch can fix this; the block has to reach main.

Ben Duncan 7ddcac53bb feat: block outbound SMTP egress via platform OVN ACL (#1001)
* feat: block outbound SMTP egress via platform OVN ACL

Add a platform egress ACL that drops outbound TCP to 25/465/587 for public
destinations on every guest, matching AWS's default outbound-SMTP block. The
control is global by default with an operator-held per-VPC exemption; tenants
cannot open the ports via a security group because the block sits above the
tenant-allow priority band. Private destinations are always exempt.

Config exposes blocked_ports_wan (nil defaults to [25,465,587], [] disables)
and egress_block_exempt_vpcs. Adds unit tests for the ACL builder, the SG
manager wiring and the config resolution, plus an e2e that digs gmail.com MX
and confirms a 5s SMTP connect is blocked while other WAN egress works.

Josh Siviour 31eb3bc672 fix: fail a credential refresh instead of extending a dead key's expiry (#995)
ec2rolecreds implements aws.HandleFailRefreshCredentialsCacheStrategy, which
aws.CredentialsCache prefers over returning the refresh error. When the cached
credential is expired or within five minutes of expiring and the refresh fails,
it hands back the same access key, secret and session token with Expires pushed
a random five to fifteen minutes out, reported as a success. Every later
refresh fails the same way, so ecs-agent signs with a credential the control
plane has already rejected, indefinitely, and nothing surfaces it.

The cache picks its strategies by asserting on the provider's dynamic type, so
returning aws.CredentialsProvider from NewProvider does not disarm it. Wrap the
provider in a type whose method set omits HandleFailToRefresh, and the cache
falls through to returning the error. AdjustExpiresBy is forwarded on purpose:
it only fires under an ExpiryWindow, which no caller sets today, but dropping
it silently would change behaviour for whoever sets one.

Fixed in imdscreds rather than at the one exposed call site, so a future caller
that wraps this provider in a cache is safe by construction.
ecr-credential-provider was never affected: it calls Retrieve uncached.

Two comments claimed the hazard was ec2rolecreds capping Expires to an hour.
That cap only ever shortens a too-far-future expiry and is unrelated.

Ben Duncan 828b5df4aa fix: pause a guest on a backend I/O error instead of handing it EIO (#977)
* fix: fail DRAIN when a volume seal failed

shutdownAndUnmount logged the volume unmount error and returned nothing, so
StopAll returned nil and the DRAIN phase ACKed success with vms_stopped set.
The coordinator then advanced to STORAGE and stopped viperblock while the seal
was still in flight, tearing the VBState envelope and leaving the guest unable
to mount its root volume on the next boot. The deploy reported success.

shutdownAndUnmount now returns ErrVolumeSealFailed when the unmount did not
seal; QMP, PID-file, fw_cfg and telemetry cleanup stay best-effort. stopCleanup
and stopOne carry it without aborting the rest of the teardown, since QEMU is
already down by then, and StopAll aggregates the per-VM failures so
handleShutdownDrain ACKs with Error set and never reports vms_stopped.

volumeMounterAdapter.Unmount was the second swallow site: it logged each failed
seal and returned nil unconditionally. It now attempts every volume and returns
the aggregate, which is what the VolumeMounter contract already described.

Terminate still tolerates a failed seal — the volumes are deleted next, so an
unsealed block map loses nothing a caller can ask for.

This does not fix the seal itself. It converts silent data loss into a refused
upgrade that an operator can act on.

* test: add the storagefault e2e suite for backend-outage guest survival

Freezes predastore with SIGSTOP to hold connections open while answering
nothing, which is the fault a timeout-free path cannot distinguish from a
slow peer. On one node that is a total outage; on three it freezes every
node but the guest's own, breaking the RS(2,1) shard floor.

The suite writes and flushes a verifiable region before the fault and
churns a separate unverified region during it, so an interrupted write is
never mistaken for lost data. The root-filesystem load runs from the
user's home rather than /tmp, which is tmpfs on this image and would move
no bytes on the root device.

* test: verify the root device is under write pressure, and size the outage

The previous guard matched /^ *vda / against /proc/diskstats, where the
device name is the third field, and read $7 which is ms_reading rather
than sectors_written. It printed empty and asserted nothing, so a green
run could not distinguish a surviving guest from an idle disk. It now
samples sectors_written twice and fails unless it advances.

The outage is sized from viperblock's absorption rather than guessed:
a workload must fill DefaultMaxPendingBytes before backpressure engages
at all, so a short freeze measures the retry budget rather than the fault.

* test: add nbdkit fault injection to the storage-fault e2e suite

The predastore freeze takes the whole storage cluster away from every
guest on it, which is too broad to run beside anything else. Removing a
single volume's NBD server is the same fault at one-volume scope: one
host, one guest, nothing cluster-wide stopped.

Both signals are here because they sit on opposite sides of the defect.
SIGSTOP holds the socket open and answers nothing, so the guest blocks
and no error reaches ext4. SIGKILL closes it, and QEMU's nbd driver at
the default reconnect-delay of 0 fails requests at once, which under
werror=report aborts the journal.

Signalling is guarded: a pid is matched on comm, our plugin and the
volume argument together, and re-confirmed immediately before the
signal, because these hosts run nbdkit for other volumes and pids are
reused.

* fix: pause a guest on a backend I/O error instead of handing it EIO

Every virtio-blk device was created with werror=report,rerror=report, so a
backend outage was delivered to the guest as EIO. ext4 aborts its journal on
that and remounts read-only, and the write that failed is simply gone. Under
werror=stop QEMU pauses the VM and holds the failed request, so a backend that
comes back resumes the guest with nothing lost.

The boot drive, the cold-boot data volume and the hot-plugged data volume all
move to stop. Alongside it the NBD transport gets reconnect-delay=30, which
pauses requests rather than failing them while a storage process restarts on
the same socket; on the legacy -drive form it has to be file.reconnect-delay,
because the bare name reaches the raw format driver, which has no such option.

The QMP heartbeat now recognises run state io-error and issues cont. After ten
attempts the instance is reported impaired and the cadence drops to one attempt
per ten heartbeats, but it never stops: QEMU holds the request for as long as
the guest exists, so a backend that returns an hour later can still be resumed.

The storagefault suite gains the fault this was written for — kill the volume's
own nbdkit, hold, then put it back on the same socket — and it now verifies a
sha256 region across the outage rather than trusting the guest to be reachable.
Three harness defects went with it: the socket-liveness poll ran unprivileged
against a 0770 directory and could never succeed, the relaunched socket was
left 0755 where QEMU needs group write, and the two variants shared one guest
so a fault in the first was diagnosed in the second.

* test: cover the io-error resume policy

* test: stop two parallel tests racing on the terminate backoff variable

* fix: report a guest paused on a backend I/O error as impaired

A guest held by werror=stop kept reporting ok on both status checks. QMP stays
responsive while the guest is paused -- cont is being sent and answered -- so
the QMP failure gate that DescribeInstanceStatus keys on never trips, and the
one state a customer most needs to see looked healthy.

Instance status now reports impaired/failed while the resume budget is
non-zero, timestamped from IOErrorSince so impairedSince is when the guest
paused rather than when it was escalated. System status reports impaired too:
a backend I/O error is an infrastructure fault, not a guest one, and that
distinction is what the two checks exist to draw. The counter is cleared by
the first poll that sees the guest running, so both clear on recovery.

* test: reap the relaunched nbdkit when the fault test ends

relaunchNbdkit detaches the server with setsid so it outlives the SSH session
that started it, and viperblockd never learned it exists. Nothing reaped it, so
every run left an nbdkit holding a socket and a cache for a volume that was
later detached or deleted -- four were found running on dev-prod against two
detached and two deleted volumes.

The PID is resolved from the socket path rather than the volume id, so a
legitimate viperblockd server for the same volume is never the one killed.

* test: prove the backend is serving before a fault is called cleared

Thawing the process a fault stopped is not the same as restoring the service.
The outage test treated SIGCONT as the end of the fault and went straight to
judging the guest, so it passed while the cluster it ran on stayed unable to
serve a single object for the next 35 minutes, and the next test would have
inherited that.

thawPredastore now puts and gets an object through every gate, with a budget,
and fails the test if the backend does not come back.

* fix: do not hand back a mount entry whose export is gone

A volume whose unmount failed kept its entry in MountedVolumes while its nbdkit
was gone. Every later ebs.mount then matched that entry and returned its socket
path, so vmMgr waited for a socket nothing would ever create and the instance
could not be started again — on dev-prod a guest stopped against a frozen
backend was left permanently stopped, four start attempts failing identically
on a socket the node had already removed.

Drop the entry when there is positive evidence the export is dead: the socket
is absent, or the recorded pid is not running. Neither can be true of a live
export, so the double-writer hazard the guard exists to prevent is unaffected.

Also make the durability test's pattern helpers report failures. The read dd sat
in a pipeline, so its exit status was discarded and the harness hashed nothing
and returned the empty-string sha256 as a checksum.

* test: report the guest console when a restart never answers SSH

A restart that reaches running but never comes back is indistinguishable from
a dead root filesystem without the serial console, and the log is gone once
the fixture terminates the instance.

* fix: converge guest port datapaths concurrently, not one deadline after another

Each guest port that misses its SB binding burns the full convergence deadline,
and applyEIPs spent them in series. Three ports belonging to long-stopped
instances therefore held a newly launched guest's EIP dark for the sum of them
before its own probe started.

AddEIP stays serial since it mutates NB. Only the waits fan out, bounded, and
sb-cluster-state-reset is now serialised with a minimum interval so concurrent
probes cannot each fire a cluster-wide resync.

* fix: refuse a stale cross-node start after the owning node is gone

The volume lease already refused a cross-node mount, but it is a liveness
claim: 45s TTL, renewed every 15s. A node that dies holding un-uploaded
writes stops renewing, and 45 seconds later nothing refuses a start elsewhere
that loads a stale backend checkpoint.

A failed seal now writes a durable marker naming the node holding the only
current copy, cleared on a seal that reaches the backend and on delete. The
lease covers a live holder, the marker a dead one.

The refusal also reaches the caller instead of being flattened to
ServerInternal, which told an operator to retry something that cannot succeed
while the holder is down.

* fix: keep the daemon's message when a start is refused

Rebuilding the error from the code alone rendered the generic ErrorLookup
text, so a refusal naming the node holding the volume reached the caller as
boilerplate about attaching volumes.

* fix(ec2): terminate detaches every DeleteOnTermination=false volume

TerminateStoppedInstance skipped the detach for a non-Boot DoT=false volume
on the assumption that Stop's Unmount had already cleared its attachment.
Unmount only clears it when the seal succeeded, so a volume whose seal failed
stayed in-use pointing at an instance that terminate then deleted, leaving it
unreachable with no owner to release it.

The running-instance path already detaches every DoT=false volume; the stopped
path now matches it, and tolerates an already-gone volume the same way.

DeleteVolume also keeps its provider error on the way out. The terminate reaper
retries the delete every two minutes and logged a bare ServerInternal, which
made a blob node being down indistinguishable from a transient fault.

* fix(ec2): DetachVolume --force releases a volume whose instance is gone

The ordinary detach routes to ec2.cmd.{instanceID} for the guest unplug, so a
volume left attached by a part-way teardown could never be detached: the
instance no longer runs anywhere and nothing answers. That also made it
undeletable, since DeleteVolume refuses an attached volume.

ForceDetachVolume already existed for this deadlock but was reachable only from
account teardown. Force now falls back to it when the instance has no responder,
which is the one case where clearing the attachment cannot strand a live guest.

* fix(viperblock): unsealed writes steer placement instead of pinning a volume

The dirty marker refused any mount from a node other than the one holding
unsealed writes. Instance start already forwards to the node that last ran the
instance and falls back after a 30s window, so that refusal turned a working
fallback into a volume that could run nowhere once its owner was gone. It
traded a rare data-loss risk for a permanent availability failure.

The marker is now a record and a warning, not a gate. A takeover logs the
previous holder and why it could not seal, then adopts the marker so the old
node is no longer treated as the better source. Live exclusion is unchanged and
still enforced by the lease.

It is also written on open rather than on seal failure. A node killed mid-write
never reaches its seal, so the old trigger left no trace in exactly the case the
marker exists to describe.

Adds 'spx admin volumes unsealed' to see which volumes would cost something if
started elsewhere.

* fix(viperblock): fence a volume whose lease moved instead of logging it

The lease was checked once, at mount, and never again. A node that lost it
kept its export up and kept writing into a volume another node owned, so
both copies advanced and the backend settled it by arrival order.

Losing a renewal now decides: another holder means tear the export down,
no holder means the entry merely aged out, so reclaim it and leave the
guest running. Fencing never seals — this node's copy is the stale one —
and leaves the dirty marker for the winner to take over.

This is not an epoch fence. It narrows the window from the 45s TTL to one
renewal interval at no write-path cost; the backend still cannot refuse a
stale writer.

* fix(network): advertise EIPs so a recycled address is reachable

The gateway switch port only asked ovn-northd to publish the router's NAT
addresses in centralised and routed modes, so on a distributed cluster nothing
ever announced an elastic IP. OVN still answers ARP for it, which is why a
first-time allocation works and hid this — but no gratuitous ARP is sent when
the address moves to a new ENI, so every host on the segment keeps resolving it
to the previous holder's MAC until its cache ages out. Reusing an address from
the pool then lands on a dead MAC and the instance is unreachable from outside.

Distributed mode needs the option as much as the others: northd scopes each
entry with is_chassis_resident(<vif port>), so the announcement leaves from the
chassis running the instance rather than the gateway, which is what distributed
NAT wants.

Converge on the already-attached path too. AttachIGW returns early once the
gateway port exists and nothing else rewrites it, so without that an existing
VPC would stay silent for its whole life.

Confirmed on dev-prod: setting the option moved three EIPs from unadvertised to
carrying their correct external_mac, each scoped to its own ENI's port.

* fix(viperblock): make the volume fence and its dirty marker ownership-safe

Four corrections to the lease-loss fence, all found in review.

Drop the reacquire path. Losing a lease and finding no successor was treated as
a lapsed entry worth reclaiming, but leases.acquire returns the cached entry —
already flagged lost, with a dead renewal goroutine — so the "reclaimed" lease
renewed nothing and the node went on writing a volume it could not prove it
owned. The two errors are not symmetric: a false fence costs one guest a
restart, a false reclaim leaves two nodes writing one volume. Fence in both
cases, and report which happened through the outcome attribute.

Surrender a lease this node cannot confirm. Renewal only noticed a loss when
the server rejected an update, so a node partitioned from NATS kept its export
up while the TTL expired and another node took the volume. Track the last
confirmed renewal and give the volume up once that ages past the point where
the server may admit another owner. Bound the renewal call too, so a hung
JetStream request cannot hold the goroutine past that point.

Do not act on a kill that did not take. Both the fence and ebs.unmount removed
the mount entry, released the lease and announced the result before knowing
nbdkit had exited — the fence then reported a writer stopped that was still
running, and the unmount sealed into a directory a live process was writing.
Wait for the exit, and on failure leave the volume mounted and say so. An
already-exited process now counts as success, which is what the caller asked.

Give the dirty marker a generation. It recorded an owner and nothing to order
two nodes' claims, so a node returning after a takeover could clear or overwrite
the winner's marker and point placement back at the stale copy. Stamp the lease
generation, refuse a write from an older one, and only clear a marker this node
still owns. A marker that cannot be written now fails the open rather than
leaving writes nothing records.

* test(viperblock): cover the stall surrender and the unmount kill guard

The two ownership cases the fence work left untested.

A holder partitioned from NATS while the winner keeps it never gets an update
rejected, so revision checking cannot see it — it has to give the volume up on
its own clock. Pins that validity sits below the server TTL with room for a
check in between, that a lapsed holder reports the loss as a stall rather than
as a takeover, and that releasing a surrendered lease leaves the entry for
whoever holds it now.

The unmount side of the kill guard: sealing under a live nbdkit writes a state
torn between two writers, so a kill that did not take has to fail the unmount
and leave the entry mounted for a retry.

* fix(e2e): keep the guest private key for as long as the key pair

EnsureKeyPair computed the PEM path from the caller's directory but wrote
the file inside the ensureOnce closure, which runs only on the first call.
Callers passed a per-test artifact dir, and ArtifactDir removes that dir
when the test passes — so the first test's success deleted the only copy
of the private key while the key pair stayed registered, and every later
call returned a path nothing had ever been written to.

Guests after the first were then launched against a public key whose
private half no longer existed, so the harness could never authenticate
and gave up after the full five-minute budget. The guests were healthy
and reachable on tcp/22 throughout, which is why this read as a storage
or network fault for so long.

The directory parameter was the defect, so it is gone: the PEM now lives
in a directory the fixture owns and removes with the key pair, and no
caller can supply one that is shorter-lived.

Also reorder the killed-nbdkit teardown. The reaper registered its own
cleanup after the detach registered one, so LIFO killed the block server
before the platform detached the disk and DetachVolume then failed with
"Node ... is in use". The detach cleanup now reaps once it is done.

* fix: stop leaking an nbdkit export when recovery cannot adopt it

Restart recovery adopts a guest's boot volume, then routinely fails the
-efi volume with "claim lease: context deadline exceeded" -- JetStream is
still catching up at daemon start and the KV claim runs on the client's
5s default. Recovery gave up on the first error and never retried, so the
export stayed live with no registry entry. At terminate the unmount found
nothing to seal, returned NotFound and killed nothing, and the process
outlived its guest holding the volume and socket open. EFI is always the
second volume adopted, which is why it was always the one that leaked.

Two changes, because either alone leaves a hole:

- rebuildMountedVolume retries the build (4 attempts, 3s apart) so a
  JetStream that is merely slow no longer orphans an export for the life
  of the process.
- unmountVolume reaps a corroborated export for the volume it was asked
  to unmount when the registry has no entry for it, so an export orphaned
  by any means is still cleaned up. The reap goes through
  reapOrphanedNbdkit, which declines anything a live process references:
  at unmount the guest's blockdev may not be torn down yet, and killing
  the server underneath it strands QEMU.

* test: hold the backend-serving probe and assert predastore readiness

The backend-outage test declared the backend restored on one successful
round trip through each gate. A gate can answer the request that arrives
just after a thaw and then lose its blob peers under the load that
follows, which is a backend that never recovered reported as one that did
-- and that is what happened: the probe reported all three gates serving
minutes before the guest was still taking BLOCK_IO_ERROR on every resume.

The round trip has to hold across three rounds now, and the count restarts
rather than decays when one fails, so a gate that serves and then stops is
the failure the hold is looking for rather than noise it averages out.

It also checks /readyz on each host and reports any failed check by name.
The round trip only proves this workstation can write through a gate; it
says nothing about which blob peers that gate can reach, and a gate one
node short of the write floor serves a small object and fails a guest. A
host that serves no admin listener is logged and skipped, since the port
is optional configuration.

* fix: scope predastore's admin port to the cluster plane in the host policy

predastore's admin listener binds the host's cluster bind_addr and serves
/healthz and /readyz unauthenticated. Readiness now names which blob peers
a gate cannot reach, which is exactly the kind of topology detail 4432 is
peer-scoped for, so 8660 joins it in the peer-scoped rule rather than the
public one.

* fix: keep resuming a paused guest at heartbeat rate after a long outage

Past ten attempts the cont dropped to one per ten heartbeats, so a guest
whose backend had come back could sit paused for another five minutes
before anything retried it. Measured on dev-prod: the backend was proved
serving through all three gates while the guest was still waiting on
attempt 60, five minutes after attempt 50.

The slowdown was there to avoid paying a failed I/O every thirty seconds
on a backend still down. That is nearly free, and five minutes of downtime
after recovery is not, so only the log line is throttled now.

* test: fail the run when a key pair name resolves to more than one pair

A create that lands twice leaves two key pairs with one name and different
material. RunInstances resolves the name to one of them while the harness
holds the private key of the other, and the only symptom is every guest in
the run refusing the key at the SSH gate — five minutes of waiting per
guest, four guests, and nothing anywhere naming the cause. Observed on
dev-prod: two pairs created a millisecond apart, both named
e2e-key-30de10ba.

One DescribeKeyPairs after the create says so outright instead.

* test: tolerate an already-released volume in the detach teardown

Teardown runs DetachVolumeWait after a terminate that releases the volume
itself, so the detach can arrive at a volume already on its way to
available. That is the outcome it wanted, and treating the IncorrectState
refusal as fatal failed a backend-outage run whose assertions had all
passed — the guest came back, every acknowledged write verified, and the
test still went red on the way out.

VolumeInUse is still fatal: that one means the volume is attached
somewhere it should not be.

* test: carry the merged suites onto the reworked key-pair and account-scoped seams

The diskperf suite arrived on dev calling EnsureKeyPair with the artifact dir
this branch removed, and DeleteVolume's metadata lookup is account-scoped now,
so the provider-failure test has to seed and delete under the same account.

* refactor: make the fence outcome a type in one const block

Four separate exported string constants with a paragraph of comment each,
passed to RecordVolumeFence as a bare string. Group them, give them a
FenceOutcome type, and take that type at both call sites so an arbitrary
value can no longer reach the metric attribute.

* refactor: move viperblockd's wire contract into a leaf vbwire package

The daemon imported viperblockd for exactly two symbols -- the fenced
volume subject and its event -- which put the storage service back on the
daemon's dependency graph to name something it only listens for.

vbwire holds the contract instead: the subject and event, the dirty
bucket name and record shape, and the read-only listing an operator tool
needs. It imports nothing from spinifex, so both the daemon and the admin
CLI drop their edge to viperblockd entirely. cmd/service.go keeps its
one, which is genuine: it constructs the service.

* docs: drop a specific host name from the start-refusal comment

Named a real dev-prod host in a comment and in test fixtures. Say what
the name is instead.

* ci: give storagefault a dedicated nightly cell

The suite is eligible for both topologies and runs on the PR gate, but no
nightly cell ran it: the permutation cells run a deliberately narrow
subset and none of the dedicated suite cells named it.

Cell 29, single-node, following eks/ecs/rds. It cannot join a permutation
cell -- it SIGSTOPs a cluster-wide service, so every suite sharing that
environment would report the outage as its own failure.

* ci: run storagefault nightly on three nodes, not one

The previous commit put its dedicated cell on a single-node runner. That was
the wrong topology and the wrong justification: single-node is RS(1,0), where
the shard floor cannot be broken and a cross-node takeover after a failed seal
does not exist, so the two assertions worth having a dedicated cell for were
the two it could not make. Cell 29 is now real-multi on ci-multi.

It also corrects the claim that the PR gate already covers the multi-node case.
The suite is eligible for both topologies, but e2e.yml's default suite list
never names it, so it has never run there. A full pass is ~63 minutes on
dev-prod bare metal, almost all of it deliberate waiting -- one test holds
predastore SIGSTOPped for seven minutes -- which is too long to add to a gate
that currently finishes well inside its budget. Nightly is where it belongs.

Consequences: a per-cell timeout_minutes, defaulting to the previous 50, since
90 minutes of suite cannot run in a 50-minute job; the permutation steps gated
on matrix.suite == '' so the dedicated cells do not also run them; and a Run
Multi Suite E2E step that builds NODES_CSV from the tofu inventory and asserts
the suite against E2E_SUITES_MULTI before running it.

* fix: stop a startup KV race leaving vpcd serving keyless guests

vpcd opens five KV buckets while NATS is still coming up, each attempt
carrying a ~5s JetStream API deadline, and applied three different policies to
the same failure: spinifex-vpc-enis was fatal, while instance-state,
security-groups, subnets and vpcs each degraded silently for the lifetime of
the process. A five-second blip during a cold start therefore decided how a
node served metadata until someone restarted it.

On dev-prod all three nodes hit this after a deploy. Two were saved by
accident: their ENI bucket also timed out, so they exited 1 and systemd
restarted them cleanly. The third's ENI bucket opened in time, so it never
crashed and ran for hours with no instance record loader. With the local state
file unreadable as well, every instance-backed IMDS leaf 404'd, cloud-init's
crawl died on ami-id and fell back to DataSourceNone, and every guest launched
on that node booted with no authorized_keys.

kvstore.OpenWithRetry retries for a bounded window before any policy applies,
logs the cause per attempt and the wait on a late success, wraps the last error
with the bucket name, and returns at once on a cancelled context. All five
opens use it. Failing to open the instance record space is now fatal, matching
the ENI bucket: the dependency whose loss stops guests logging in should not be
treated more leniently than the one whose loss stops ENI resolution.

Also fixes the reason the fallback was load bearing at all. The local state
file was written 0600 and vpcd reads it as a different user in the shared
spinifex group, so the local-first path had never once worked and its
mtime+size cache had never fired. It is 0640 now, set with an explicit Chmod so
an inherited umask cannot undo it.

Closes mulga-gtpzz, mulga-dhqxr. Still open: mulga-mm2oc, IMDS serving an
unresolvable instance as "no key pair" with nothing logged.

* fix: scope the ime-* firewall accept to IMDS and VPC DNS only

The per-tap OVS demux delivers any guest packet addressed to
169.254.169.254 or .253 onto an ime-* host port regardless of L4 port,
and iifname "ime-*" accept then admitted all of it. Every wildcard-bound
host service — sshd, the AWS gateway, northstar, the console — answered
guest packets on those addresses; only asymmetric reply routing kept the
handshake from completing, and a guest could still drive northstar to
recurse unthrottled. Scope the accept to IMDS (.254:80) and VPC DNS
(.253:53), letting everything else fall through to policy drop.

* docs: document the instance-to-host plane and how to protect it without the ISO

The metadata/VPC-DNS link-local plane (169.254.169.254/.253) is served by
host services and is invisible to a NIC-level or cloud firewall, since the
traffic is intra-host on the OVS bridge. Explain that the ISO ships the
scoping rule armed, that the binary installer ships the firewall off, and
that a non-ISO install must enable it with setup.sh --firewall=on or
firewall_enabled=true. Include verification from an instance and the host.

* fix: withhold the IMDS meta-data listing when the instance does not resolve

Every omission from the meta-data root is a positive claim about the instance —
public-keys/ absent means "launched without a key pair", and cloud-init believes
it, writes no authorized_keys and boots the guest keyless. So resolving the
instance was best-effort for a listing whose whole meaning depends on it: a
backend error or a miss shortened the listing instead of failing it, and nothing
anywhere recorded that the answer was a guess.

Withhold the listing with a 500 instead. cloud-init retries a 5xx and cannot
retry a 200 that is merely wrong, so this converts a permanent silent failure
into a transient loud one. servePublicKeys already had this policy for the leaf;
the root is what contradicted it.

A profile lookup that fails still serves the listing minus iam/, and now logs.
The key pair is the field a guest cannot recover from losing, while a missing
role surfaces through the credentials leaf, which reports the miss itself.

Also stops the storagefault cross-node test failing on its own access path. It
tolerates the pattern changing across a takeover, but readPattern needs sudo,
and a volume opened from the backend checkpoint may predate cloud-init writing
its sudoers drop-in — indistinguishable from an unreadable device at the dd call
site. It now checks sudo first, and reads cloud-init's recorded datasource to
tell a rolled-back root filesystem from IMDS never having answered, failing
loudly on the latter rather than accepting it as storage loss.

Ben Duncan b6d01370dd fix: render northstar's recursion allowlist so a node is not an open resolver (#993)
* fix: render northstar's recursion allowlist so a node is not an open resolver

northstar.toml is written with allow_recursion = false and an allow_recursion_from
list built from cluster membership, so a freshly formed node serves recursion to
the cluster and refuses it to the internet.

The list is the node's own bind and advertise addresses plus every peer's host,
with any port stripped. Both local addresses matter: a node's resolv.conf points
at its own advertised address, so the query arrives from that public IP over lo
rather than from 127.0.0.1, and an allowlist of loopback alone would stop every
node resolving internal names.

Guests are covered without appearing in the list. vpcd's per-tap DNS shim relays
guest queries to a node's :5300 from a node address, so trusting the nodes trusts
every guest behind them and no guest CIDR is needed.

The template comment carries the caveats for allow_recursion = true, since the
cost of setting it is remote from the setting: an open resolver is found by
scanners within hours and gets the node's whole address range blocklisted, which
is an outage for every tenant on it.

The list is rendered at formation, so a node added later is not in its peers'
files. Regenerating it live from membership, as the daemon already does for
peers.nft, is follow-on work tracked on mulga-t3mub.

* chore: pin northstar to the recursion ACL and atomic zone reload

The recursion allowlist this branch renders is enforced by northstar's
RecursionPolicy, which lands in dev at a0e741e. CI resolves northstar from
go.mod rather than the workspace, so the build failed on NewRecursionPolicy
being undefined until this pin moved. The AWS SDK bumps come with it.

Josh Siviour c767f2b6ee feat: judge DescribeInstances completeness by responder identity, and resolve IMDS locally (#985)
* feat: stamp the owning node's AZ on the instance record

RunInstance never persists a node's AZ onto the stored instance, so
today only the launching node's own ProjectInstance call can produce
a correct AZ for a describe. Add VM.AZ, carry it on InstanceStatus
since it is placement observed by the running node, and stamp it in
WriteRunningSet alongside Status.LastNode from the node's own
config.AZ.

* docs: trim the AZ field comment to the project's three-line limit

* fix: identify Gather responders by node, not by frame count

utils.Gather previously counted reply frames toward completeness, so
two subscriptions replying from one host (a daemon mid-restart) could
satisfy a fan-out while a genuinely configured node stayed silent.

Every daemon reply now carries an X-Node-ID header set by the shared
response helpers via nats.Msg.RespondMsg, so Gather can attribute each
frame to the node that sent it. Gather gains a CollectionMode
(CollectServeData preserves today's early-exit behavior;
CollectUntilDeadline collects to the full deadline for absence-proof
callers) and returns node-identified Frames plus Responders/
SuccessResponders/ErrorResponders sets. Identity mode retains only the
first payload seen per node; a disagreeing later frame from the same
node flags a conflict but never overwrites the retained data.

Node identity uses one namespace across the reply header,
config.ClusterConfig.Nodes keys, daemon.Heartbeat.Node, and
vm.VM.LastNode, all traced back to Daemon.node - confirmed to already
agree, with a new test asserting it at runtime.

This is a mechanical caller-side follow-on: every existing
utils.Gather caller now reads frame.Data instead of frame directly.

* feat: thread configured node set to DescribeInstances

GatewayConfig gains NodeIDs, the keys of config.ClusterConfig.Nodes,
distinct from the existing ExpectedNodes count. awsgw builds it from
cluster config and wires it into GatewayConfig. The DescribeInstances
action passes gw.NodeIDs through instead of relying on
gw.DiscoverActiveNodes(ctx) at that call site, so completeness can be
judged against the nodes that are actually configured rather than the
nodes that happened to answer a discovery probe.

* fix: judge DescribeInstances completeness by node identity

DescribeInstancesChecked now judges completeness on decoded frames
against the configured node set (ValidResponders) rather than on
Gather's frame/byte counts, which cannot know the describe schema. A
node that answers with a nil Reservations list is a valid responder,
not an invalid one - the existing merge guard on Reservations != nil
governs how frames combine, not whether the node counted as having
answered.

The explicit-instance-ID 404 path now collects with
CollectUntilDeadline so a node that hasn't replied yet cannot be
mistaken for a node that has nothing to report; general listing stays
on CollectServeData. Any ambiguity - an unidentified frame, a node
appearing in both the success and error sets, a node replying twice
with disagreeing frames, a Gather cap hit, or an empty/unset node set
- suppresses the NotFound rather than risking a false one.

* fix: let a describe by instance id stop once every id is found

CollectUntilDeadline made every DescribeInstances with explicit ids wait the
full 3s fan-out deadline, measured at 4650ms against 1655ms before, on a
healthy cluster where all three nodes answer in about a millisecond.

Gather gains a Settled predicate, consulted only under CollectUntilDeadline,
that ends collection once the replies already answer the question. Absence
still pays the whole deadline, and an instance the caller cannot see is
filtered out of every frame so it takes the absence path too, which keeps the
two NotFound answers indistinguishable in time.

* refactor: resolve IMDS instance metadata local-first, drop the fan-out

IMDS only ever serves a guest on its own node, so a DescribeInstances
fan-out to the whole cluster is unnecessary latency and load. Resolve
from the node's own on-disk VM state first, falling back to a direct
record-space read for an instance that has moved off this node.
Neither path issues a NATS request.

* perf: cache the local instance state parse for IMDS lookups

IMDS request rate is guest-driven and unbounded, so re-reading and
re-parsing the whole on-disk VM state on every request does not
scale with VM count on a node. Cache the parsed state and only
re-read when the file's mtime or size changes; a stat or parse
failure clears the cache and falls back to the record space rather
than serving a stale hit.

* fix: share ManagedBy visibility rule between DescribeInstances and IMDS

Extracts IsInstanceVisibleToCaller so account ownership and the
platform-managed hide rule live in one place instead of two
independently maintained copies.

* refactor: decouple IMDS instance lookup from the daemon package

handlers/imds no longer imports daemon: NewIMDSServiceImpl now takes a
localStateReader and a recordLoader interface instead of a dataDir
string, and vpcd (the composition root for both planes) constructs
both adapters, including the stat-guarded local-state cache that used
to live inline in handlers/imds. Either adapter may be nil, degrading
that source to a miss rather than failing IMDS to start.

* test: move the local state reader test to an external package

* chore: exempt export_test.go from the external test package check

The check's own remedy text tells you to move unexported hooks into an
export_test.go, then flags that file for being in-package — which it is by
definition, since exporting internals is its whole purpose.

* fix: bound how many describes may hold a full fan-out deadline

A describe naming an instance the caller cannot see is filtered out of every
frame, so it never settles early and holds a gateway goroutine and inbox
subscription for the whole 3s deadline. Issuing those is free for the caller,
so nothing stopped a burst of them pinning unbounded gateway state.

Absence proofs now draw on a fixed budget. Past it, callers get a retryable
RequestLimitExceeded rather than being queued, since queueing would let the
backlog grow. The decision is taken before any reply is read, so a nonexistent
id and another account's id throttle identically and the throttle cannot become
the timing oracle the deadline exists to close.

* perf: settle describe-by-id on responder coverage, not the full deadline

Every describe-by-id was paying the whole 3s fan-out deadline whenever the
requested instance was not in a running-instance frame — which includes a
stopped instance, a terminated one, an id belonging to another account, and
an id that does not exist.

Gather gains ResponderGrace: once every ExpectedResponders node has
answered, collection closes after a short grace window instead of running to
the deadline. Core NATS gives a request only to the subscribers present when
it was published, so an overlapping subscription replies alongside the first
and one that arrives later never receives the request at all. Waiting past
full coverage cannot find a reply that full coverage missed. The window is
armed once and never extended, so a node replying repeatedly cannot hold the
fan-out open. The full deadline is now paid only when a node stays silent,
which is the case it was always meant to cover.

The stopped and terminated bucket queries now run alongside the fan-out
rather than after it, so their latency overlaps it instead of adding to it.
They feed a shared instanceSettler that ends collection as soon as every
requested id has been seen, skipping even the grace window.

The timing oracle is unchanged. An instance the caller cannot see is
filtered out of every source before the reply is sent, so it takes the same
path as an id that does not exist: both answer NotFound after full responder
coverage, and remain indistinguishable in time.

* fix: stop parallel tests racing the terminate backoff seam

terminateRetrySleep is a package global, and every test that needed it
neutered swapped it and restored the old value from t.Cleanup. Those tests
run in parallel, so two cleanups could write the seam at once — a real data
race the detector caught once enough parallel tests shared the binary.

Installed once in TestMain instead. Nothing in this package wants the real
backoff, so there is no value in restoring it per test.

Josh Siviour 3680e5b5bc feat: render predastore admin_port and gate deploys on /readyz (#936)
* feat: render predastore admin_port and consult /readyz in health probe

Spinifex now allocates predastore's admin listener port (8660, after the
existing gate/blob/meta bases) and renders admin_port into both the
single-node and multi-node predastore.toml templates. The daemon's health
probe consults /readyz over that port on the two weak paths (single-host
gate fallback and hosts running no meta node), falling back to the prior
behavior when no admin port is configured or the listener refuses.

* build: pin predastore to the release carrying Host.AdminPort

The admin port field this branch reads is new in predastore, so CI could not
compile against the pinned version: go.work hid the gap locally by resolving
predastore to the checkout instead of the module.

appliance connect, a new reconcile pass re-creates any registry index whose
pg table is missing and re-enqueues ingest from its persisted SourceSpecs,
so a torn-down appliance heals without operator action and keeps its KB id.

Josh Siviour f9c84919ef feat: co-served GPU model bundles (vLLM + TEI) with family-aware reaper (#845)
* feat: co-served GPU model bundles (catalog, lifecycle, embed/rerank routing)

Serve the generative LLM, embedder and reranker as one co-resident GPU
bundle: EMBEDDING/RERANK catalog modalities + co-serve group, bundle-aware
admission (one GPU claim sized to summed member VRAM), single-flight one-VM
launch with a member->port EndpointRecord, DynamicEndpointResolver member
routing. Ochrevector embed/rerank/token-introspection resolve through the
resolver (static single-endpoint map retired); rerank degrades to plain KNN on
absent/failure. Public InvokeModel-embeddings and top-level Rerank deferred.

* feat: co-serve vLLM+TEI bundle image with per-engine readiness

Replace the single-model vllm-serve unit with a generic bedrock-serve@
systemd template driven by per-member BEDROCK_* env files, dispatching to
vLLM or text-embeddings-router by engine and binding each member to its own
port and weights device. TEI serves directly on its serve port; readiness
probes each member on the route its engine answers (vLLM /v1/models, TEI
/health) with the engine family carried end-to-end from the catalog.

* fix: serve nomic embedder correctly in the co-serve bundle

Bound embeddings requests to the TEI client batch limit so a large
document's chunks are split across requests instead of 422ing. Serve
nomic with explicit mean pooling, since the flat weights layout omits
1_Pooling/config.json and TEI would otherwise default to CLS. Add
bge-base-en-v1.5 as a standalone alternative embedder.

* fix: make the bedrock reaper family-aware and pin-safe

A pinned endpoint is now exempt from terminate-and-relaunch on scrape
failure, mirroring how it is already exempt from idle reclaim, so a
transient unreachability can no longer tear down operator- or
commitment-managed serving.

A bundle with no generative vLLM member exposes no vLLM load metrics, so
it is liveness-probed on /health and kept warm rather than scraped for
idleness on a route it does not serve and reaped in a loop.

* test: lock in co-serve group-member convergence to one VM

* fix: pin self-host HF repo/revision in catalog and stop nested config flattening

Carry HFRepo/HFRevision per self-host catalog entry; weights pull defaults
--hf-repo and --revision from them so a bare pull cannot silently grab a
regressed upstream main (the nomic v5 config.json duplicate-field break).
Restrict fixed config filenames to the repo root so a nested config.json
(sentence-transformers 1_Pooling/) is dropped instead of flattening onto the
model config, and refuse any two source paths that collide at one dest key.

* fix: let endpoint delete clear an account-scoped pinned record and report honestly

A bare 'endpoint delete' resolved the Global key, which never held a pinned,
account-scoped record, then printed 'torn down' over the idempotent no-op while
the record survived. Add --account to the delete command so an operator can
target the account 'endpoint list' shows, and return DeleteEndpointOutput.Removed
so the CLI names a real teardown versus a lookup that found nothing and points
at --account. A gone VM already tolerates NotFound, so a scoped delete clears a
record whose instance was terminated out of band.

Josh Siviour ea4e7e3fb0 fix: log every duration as integer milliseconds under a _ms key (#827)
slog renders a bare time.Duration as an int64 nanosecond count and names
the unit nowhere, so every duration field in the fleet read like
"elapsed":135000000000. The repo idiom of .Round(time.Second) changed
the value without changing the shape and truncated every sub-second
measurement to zero.

otelsetup.Millis converts a duration for logging under a snake_case key
ending in _ms, and TestSlogDurationConvention type-checks ./spinifex/...
and ./cmd/... to fail the build when a raw Duration reaches an slog call
or a Millis value is logged under a key without the suffix. It found 55
sites across 34 files, well past the sites a grep for time.Since shows,
because most durations come from a config field or a package constant.

A handler-level ReplaceAttr would fix every site at once but can only
emit d.String(), which Elasticsearch maps as a keyword and nothing can
aggregate over.

Ben Duncan 225bf65a8e feat: EBS export tunables, teardown reapers, fan-out and OVN fixes (#800)
Merges `feat/ebs-export-tunables` (83 commits) into dev. The branch could not be rebase-merged because it carries five merges from dev, so it lands as a squash.

## What is in it

- **EBS export tunables** and the nbdkit/viperblock export path they configure.
- **Teardown reapers and backoff** for S3 buckets, load balancers, gateways, spot requests, certificates, endpoints, elastic IPs and network interfaces, so a dependent that keeps failing is backed off rather than retried hot.
- **Retry and tolerance paths**: ECS IAM service init, ECR signing keys deleted between the list and the read, an unreadable signing key at awsgw startup, and an ECS instance-profile policy attach converging on a stale read.
- **Key pair validation reads the material by name** instead of listing the account, closing the `InvalidKeyPair.NotFound` race that a single-replica LIST could produce.
- **Concurrency and fan-out**: concurrent metadata document fetches, bounded metadata reads for describes, and the node-discovery timeout removed from every fan-out call.
- **OVN correctness against the configured NB cluster**: the flows barrier, nexthop MAC binding, and stopping a compute node from running the package's standalone database.
- **nats-js-watchdog can re-arm itself.** The escalation check ran above the probe loop while the only line that cleared the counter sat below it, so a latched watchdog could never observe a recovery. It now probes first and decides second, and says so once per latch rather than once per tick.
- **CI**: 19 commits of nightly and build-pipeline work.

## Verification

`make preflight` green locally. Build and Test, Integration Tests, Race Detection, and Lint and Security all green on `c2da0385`.

## Known red, not introduced here

Two nightly cells fail on this branch and are pre-existing:

- **cell-10** — a partial OVN IPsec enable leaves `NB_Global ipsec=true` asserted cluster-wide while two of three chassis failed their local reconcile, black-holing cross-chassis guest traffic for roughly 5.5 minutes while every health signal stays green.
- **cell-19** — a total layer-3 egress blackhole below a correctly and promptly programmed NAT/EIP datapath, aggravated by a natuplink probe whose retry budget outlives the test's own wait, so it can never emit its FAIL verdict.

Both are filed separately and should be weighed before a release is cut.

Ben Duncan 42d87d7a5a feat: EBS export tunables, plus blob-read fault isolation for ebsmetadata (#799)
* feat(ebs): make nbdkit thread count and per-volume read cache configurable

Both numbers that set a volume's export concurrency and memory were
hard-coded: nbdkit ran on its own default of 16 threads per connection
because no -t was ever passed, and the read cache was a 128 MiB literal in
the mount path. Neither could be changed without a recompile, and neither
was visible in the logs or the process argv.

Add default_threads and cache_size_mb to [nodes.<node>.ebs]. Defaults are
unchanged, so a config that does not set them behaves exactly as before.

CacheSizeMB is a pointer so an explicit 0 (cache disabled) stays
distinguishable from an unset key, matching how ViperblockConfig treats its
own toggles. -efi volumes stay uncached regardless.

Validation is a range check only. Both are operator tunables applied per
nbdkit process, and there is one of those per volume, so the host cost is
the value times the volume count -- left for the operator to weigh rather
than second-guessed here.

* feat(security): arm the firewall by install path and sync the clock at firstboot

The host firewall armed itself from a code default, so a curl-to-bash install
onto an existing Debian or Ubuntu machine applied a default-deny INPUT policy
seconds after bootstrap. Anything the operator was already running that is not
on the allow list stopped accepting connections, with nothing logged and no
config key to set beforehand — no template writes firewall_enabled, so every
install fell through to the default.

Arming is now the install path's decision. setup.sh takes --firewall=on|off and
records it in /etc/spinifex/firewall/mode, defaulting on under ISO_BUILD and off
everywhere else: the ISO is an appliance on hardware we define, a package install
is a guest on a machine that was already doing something.

firewall_enabled becomes a three-state *bool so "unset" and "explicitly false"
stay distinguishable. Flipping the default to false instead would have torn down
a working policy on every existing node, because false is an instruction to
disable rather than an absence. Resolution is config, then mode file, then on, so
a node installed before any of this keeps what it has.

The ISO had the opposite problem. setup.sh is the only place that enables
spinifex-firewall.service and it returns before that line under ISO_BUILD, with
no systemd in the chroot to talk to. Nothing else enabled it, so after a reboot
the ruleset — runtime state — was gone, and ReconcileFirewall short-circuited on
an unchanged peer file and never put it back. An ISO node was firewalled until
its first reboot and open permanently after. firstboot now enables the unit, and
the reconcile checks the table is loaded rather than treating an unchanged peer
set as proof the policy is applied.

Two policy changes: 443 is held for the nginx TLS edge so that rollout needs no
per-node firewall change, and the SSH port is read from sshd_config and its
Include drop-ins instead of being hardcoded to 22 — a host on Port 2222 was
allowed exactly one port that was not the one it uses, and ct state established
kept the operator's session alive until they disconnected. 53 stays open on every
node, now with a comment saying so: northstar serves public authoritative DNS.

Clock: firstboot steps and waits for sync before spx admin init mints
credentials, since a certificate issued against a wrong RTC carries a NotBefore
that outlives the correction. Bounded to 60s and non-fatal so an air-gapped
install still completes, and once is enough because rtcsync writes the corrected
time back. A chrony drop-in replaces Debian's makestep 1 3, which stops stepping
after three updates and then slews at roughly 7 seconds a day — a node that
burned those before the network came up never visibly converged.

* fix(security): let a node join a cluster whose firewall is already armed

Expanding a single-node ISO install into a cluster could not succeed. Two
independent blockers, both from the same root: the peer set is derived from
converged cluster state, but the ports needed to reach convergence are gated
on that same set.

The formation port is peer-scoped, and a node dialling in to join is not a
peer yet, so the handshake was dropped rather than refused and the joiner
retried in silence until it timed out. It cannot simply move to the public
rule: outside formation the same port carries the daemon cluster manager,
whose /health and /local/* routes report node topology, service inventory and
running instances unauthenticated. So it is opened for the formation window
only, by spx admin init, and closed again on every exit path.

The reconcile then deadlocked. Holding out for the full chassis list is right
on a node with no policy loaded, but on one armed for a smaller cluster the
ports a joining node needs in order to register its chassis are exactly the
ones the stale set blocks, so the list can never complete. Widen the peer set
on the tunnel set already loaded, and report the partial state so the caller
retries sooner than the steady-state interval. A converged cluster whose
Southbound DB is briefly unreadable is still left untouched.

* docs(install): explain the firewall around cluster formation

An ISO-installed server is a cluster of one, and its firewall admits internal
cluster traffic only from members it recognises. Forming a cluster out of such
servers therefore needs the firewall off first: step 3 of the multi-node guide
has each server dial node 1's OVN database on the raft ports, and those are
peer-scoped like everything else on the cluster plane. Neither guide said so,
and the failure is a silent drop that looks like a network fault.

Both guides now walk the off / form / on sequence, and the multi-node guide
gains a reference section covering which ports are public, how arming differs
between the ISO and the binary installer, and how to verify membership landed.

Re-enable the boot-time unit whenever the daemon arms the policy. Disabling
the firewall to form a cluster also disables that unit, so re-arming used to
look complete while leaving the node bare after its next reboot.

* fix: make the ISO-to-cluster conversion path work end to end

Forming a cluster from four ISO-imaged servers surfaced a run of bugs that
share a starting state CI never exercises: the ISO delivers an initialized,
armed, running node, while the conversion path was written against the binary
installer's unconfigured one.

- install-node.sh never disarmed the host firewall, so nodes 2 and 3 could not
  dial the first node on the OVN raft ports and formation could not proceed. It
  now owns the whole lifecycle: disarm, form, re-arm, then verify the loaded
  policy against the expected peer set.
- spx admin init left the admin access key and secret empty on the preserve
  path. The pair cannot be read back, and the IAM store is rebuilt by formation,
  so the empty strings reached every joiner's bootstrap.json and crash-looped
  awsgw. It is reissued instead, and IAM seeding now skips an empty admin block
  rather than taking the gateway down on every restart.
- node-reset.sh left /etc/default/ovn-central behind. Raft membership lives in
  that file, not in the databases the reset deletes, so ovn-central recreated
  the database as a cluster member dialling a peer that had itself been wiped.
- node-reset.sh also destroyed the installed firewall policy, which nothing
  regenerates. set-peers then failed on every attempt and the node stayed open
  permanently and silently. The arming mode is read before the wipe and the
  stage regenerated after it.
- spinifex-firewall-apply rejected every verb when the policy file was missing,
  including disable. Turning the firewall off is the recovery path, so that left
  a node that could be neither armed nor disarmed.
- viperblock exited 0 on a fatal startup error, so Restart=on-failure never
  fired. During formation its JetStream bucket has no leader yet, so the EBS
  provider died for good and every volume request failed with no responders.
  predastore and qemunbd had the same bug.
- spx admin images import created image directories at 0700, so the first sudo
  import locked group members out of a tree deliberately made group-writable.

Three of these hid behind checks that cannot succeed: ovn-sbctl show against a
clustered database, and the OVN northbound and southbound waits in setup-ovn.sh.
All three failed to stderr and let the run continue, so a check that could never
pass was indistinguishable from one that was merely slow.

The USB install guide claimed the ISO leaves Spinifex unconfigured and told the
operator to run spx admin init. firstboot has always done that itself, so the
guide now describes what the ISO actually produces and how to start using it.

* fix: let spread placement launch across every node

A spread placement group reserved four distinct nodes correctly and then failed
the launch with ServerInternal, having started only two or three of them. The
scheduler was never at fault; two faults downstream stopped the instances
following the reservation.

vpcd subscribes to vpc.add-nat with QueueSubscribe, which delivers one message
at a time, and the handler holds its reply across the OVN flows barrier. The
45s caller deadline was sized against a single 30s barrier, which is right for
one instance and wrong for the N a spread launch issues at once — the third
request waits behind two full barriers and times out. That one subscription now
overlaps its handlers under a bounded semaphore. Each barrier still syncs after
its own write, so the guarantee is unchanged while N barriers collapse into
roughly one.

With the requests overlapping, every barrier still ran to its alarm.
install-node.sh computed OVN_REMOTE after building the database nodes and gave
it only to compute nodes, so the database nodes were configured without
--ovn-remote. setup-ovn.sh writes ovn-northd's NB/SB connections from that list
and skips it on the localhost default, and it already documents what follows: a
northd dialling only its local member stops advancing nb_cfg once raft
leadership moves, wedging ovn-nbctl --wait=hv. The list is knowable before any
node is touched, so it is computed first and passed to the database nodes too.

Nothing reported an OVN fault while this was happening. Every chassis was
registered, ovn-controller and IPsec were up, and the raft cluster was healthy.
The only signal was the barrier logging that it had overrun and was continuing
without confirmation — which reads like slowness and was a permanent wedge.

* perf: run guest NICs on vhost-net with multiqueue

Guest-to-guest VPC throughput measured 1.68 Gbit/s single-stream against
21.8 Gbit/s host-to-host on the same underlay, and did not improve with
more streams. QEMU's -netdev tap defaults vhost to off, so the whole
datapath ran in the main loop thread in userspace: that thread sat at
59-65% CPU while all four vCPU threads idled at ~4%.

Every tap netdev now carries vhost=on, and VPC ENIs additionally run
multiqueue at min(vCPUs, 8) queue pairs. Multiqueue needs all three of
the tap, the netdev and the device to agree, so TapNetDev and NetDevice
derive the netdev options and the 2N+2 MSI-X vector count from one queue
figure rather than leaving callers to keep them in step.

The QMP hot-plug path takes the same options as cold boot, with a test
comparing it against the rendered cold-boot strings so the two cannot
drift. MMIO machines stay single-queue: they have no MSI-X.

* ci: check out the sibling repos the go workspace needs in the ISO cells

* ci: skip cell-21 workload cleanup when the workload never ran

* ci: size the cell-21 node at 8 GiB and keep its serial log

* ci: keep the cell-21 node diagnostics alongside the serial log

* fix: let the daemon open /dev/vhost-net and delete multi_queue taps

Enabling vhost=on broke instance launch two ways. DevicePolicy=closed gates
the cgroup device list before capabilities are consulted, so QEMU's open of
/dev/vhost-net returned EPERM despite CAP_DAC_OVERRIDE; add the device to the
allow list and bump the unit version. Separately, `ip tuntap del` re-opens the
device with TUNSETIFF and fails with EINVAL on a multi_queue tap, leaking it on
every teardown; route deletion through `ip link del`, which is flag-agnostic.

* perf: default guest NICs to a single queue

Multiqueue measured a net loss. Spreading one flow across queue pairs reorders
packets and TCP reads that as loss: a 4-vCPU guest fell from 1.76 to 1.50
Gbit/s, with cwnd collapsing on spurious retransmits. The host overlay funnels
a node pair onto one softirq core, so the extra queues have no headroom to win
back what the reordering costs. Keep the plumbing and its tests behind
MultiqueueNICs so re-enabling is one line once that funnel is fixed.

vhost-net stays on unconditionally; it moves the datapath off the QEMU main
loop, measured at 60% of a core under load against 3% with it.

* fix: raise the UDP receive buffer for predastore's QUIC transport

Predastore carries blob, meta and raft over QUIC and quic-go asks for a 7MiB
receive buffer. Left at the kernel default of 208KiB it silently dropped
datagrams under load: the four-node cluster had shed 80k-125k each, which
failed shard writes, put raft into repeated elections, and ultimately handed
guests an I/O error that cost two of them their root filesystems.

Adds a sysctl stage writing /etc/sysctl.d/99-spinifex-net.conf, so the setting
lands in the ISO image and on every node push rather than living in a runbook.

* ci: give the cell-21 workload an identity the node accepts

* feat: tie the guest MTU and NIC multiqueue to ipsec_enabled

ESP costs 34 bytes on top of geneve's 58, so a cluster running the overlay in
plaintext can advertise 1442 instead of 1408 — worth roughly 10% of guest
throughput. Derive it from network.ipsec_enabled rather than hardcoding the
conservative figure.

Multiqueue moves with the same flag, because its sign depends on it. Behind
IPsec it costs ~12%: ESP has no L4 ports, so RSS funnels a node pair onto one
core and extra queues only reorder packets, which TCP reads as loss. Without
IPsec the sending host's single vhost thread saturates first and queues are
worth +54%. IPsec on with multiqueue on is the worst of the four combinations,
so it stops being a standalone knob and becomes vm.Deps.MultiqueueNICs.

The reconciler only ever created a subnet's DHCPOptions row and never revisited
it, so the create-time MTU stuck for the life of the subnet and this change
would have applied to new subnets only. Worse in the other direction: turning
IPsec back on would have left subnets advertising 1442 over ESP, which drops
large segments with no ICMP to recover from. applySubnets now diffs and updates
in place.

reconcile.Config takes IPSecDisabled rather than IPSecEnabled so the zero value
is the conservative MTU — a caller that forgets it is merely slower.

* docs: add an install-time performance tuning guide

Measured on the four-node cluster rather than inferred: the UDP receive buffer
sysctl, what IPsec actually costs and why, the multiqueue sign flip, the overlay
MTU budget, and the jumbo-frame check that must precede enabling it.

A starter doc — several sections end in an open question rather than a
recommendation.

* ci: keep the cell-21 node alive for the workload step

* ci: collect the cell-21 qemu log and widen its timeout

* feat: derive the guest MTU from the fabric, and deepen the virtio NIC config

The overlay overhead is passed on to the guest rather than hidden from it.
Hiding it means running the fabric far enough above 1500 that a standard guest
MTU fits in the headroom, which is what the large public clouds do — but they
own the switches. On a fabric we do not control, the honest figure is the one
the path can carry, and a jumbo underlay should reach the guest: 9000 gives
8942, or 8908 with IPsec. network.underlay_mtu is the lever; SubnetMTU spends
it. Configured rather than probed, because a node's own NIC MTU says nothing
about the switch between it and its peers.

host_mtu sets VIRTIO_NET_F_MTU so a guest that never takes a DHCP lease —
statically addressed, or IPv6-only — still learns the ceiling.

rx/tx_queue_size raise the virtio ring from QEMU's default 256. That default is
a packet-rate ceiling rather than a memory saving: a vCPU preempted for a
fraction of a millisecond fills all 256 slots and the overflow is dropped.

ethtool is the only way to read NIC offload, ring and channel state, so a node
without it cannot be diagnosed for throughput at all.

* ci: give the cell-21 workload its own guest key

* fix: set the guest MTU on the tap, not just in the guest

The tap was created and brought up without an MTU, so it stayed at the
kernel default of 1500 while DHCP and host_mtu told the guest something
else. Harmless at 1442; it silently blackholed every large frame on a
jumbo underlay, with no ICMP back because the drop is at the first hop.

TapSpec.MTU comes from the same guest overlay MTU the DHCP option and
host_mtu already use, and is applied in the bring-up call so a size the
fabric cannot carry fails the launch instead of degrading quietly.

* fix: stop setting tx_queue_size, which QEMU caps at 256 for tap

QEMU only honours a tx_queue_size above 256 for vhost-user and
vhost-vdpa backends. On a tap it rejects the value outright rather than
clamping it, so every launch died with "must be a power of 2 between
256 and 256" and the instance went straight to terminated.

rx_queue_size is unaffected and stays at 1024. A test pins the absence
of tx_queue_size across machine types and queue counts.

* docs: lead the tuning guide with the overlay segmentation finding

The guide's headline was a 5.4x that came almost entirely from turning
IPsec off, and it treated MTU and the fabric as the main levers. The
host reaches 92.6 Gbit/s at MTU 1500 on the same NIC, so the fabric is
not the constraint and the encrypted default is not the thing to tune
away from.

Adds the host-versus-guest comparison up front, documents
network.underlay_mtu, and makes the missing segmentation offload the
first open question.

* ci: stop deselected matrix cells failing in teardown

* docs: quantify what disabling overlay IPsec is worth

The guide described the trade without the numbers an operator needs to
make it. Adds the measured 4.9x, notes that the MTU and multiqueue
changes follow ipsec_enabled rather than being separate knobs, and
records two transition hazards: a stale wide MTU on running guests, and
RunInstances failing while the OVN flows barrier catches up with the new
SAs.

* ci: collect and retain the e2e benchmark and cluster logs

Cells 21 and 22 both copied two paths that only ever exist on the nodes, so
the benchmark JSON was never uploaded and cell-22 collected nothing at all.
Both now gather what they actually produce, and keep it for 90 days.

* fix: quieten spx by installing an explicit CLI logger default

spx never set a process logger, so it inherited whatever a linked package
left behind — until now a JSON handler at Info on stdout, interleaving
library log records with command output and breaking piped use.

Execute() claims the default before any command runs: text on stderr,
LevelError, so commands report failures through their own stderr writes and
libraries stay quiet. --verbose/-v raises to info and SPX_LOG_LEVEL sets an
arbitrary level, the flag winning over the environment. Service subcommands
still call initTelemetry, which replaces the handler outright.

No root --debug flag: viperblock, qemunbd, nats and awsgw each define their
own --debug with a service-specific meaning, and a root persistent flag would
shadow inconsistently depending on the command.

The guard test samples the handler at package-init time rather than inside
the test, because tests in this package start services that install their own
logger legitimately.

* feat: private /admin/CreateAccount for self-service tenant signup

Add POST /admin/<Method> to the AWS gateway: SigV4-signed, JSON in and
JSON out, callable only by an IAM user in the super-admin account holding
spinifex:<Method>. CreateAccount is the one method, so a signup form can
provision a tenant without an operator shell. No new service, port, unit
or certificate — it mounts inside the gateway's existing authenticated
group and inherits its auth, throttling and tracing.

Provisioning is resumable rather than transactional, which fits stores
that have no transaction. Two CAS creates carry the correctness: the
client token admits one in-flight attempt and makes a lost response
replayable for 24 hours, and the name reservation makes duplicate account
names impossible. Every step after the account exists is create-if-absent,
so a retry with the same token finishes the job instead of failing.

The CLI and the endpoint share one provisioning helper, which closes a
gap on both at once: CreateAccount never checked names, so running
`spx admin account create` twice produced two accounts that differed only
by ID.

The response waits for the account's default VPC over a new
ec2.EnsureDefaultVpc request/reply, rather than trusting the existing
fire-and-forget iam.account.created publish — credentials for an account
that cannot launch anything are worse than a slower call.

[signup] max_accounts bounds how many accounts may exist; absent means
uncapped, which is what every cluster does today.

* fix: stop the awsgw template hardcoding one deployment's console URL

console_url shipped as https://console.spx3.com, so every fresh install —
including an on-premise cluster that will never run signup — was
configured to point new accounts at our console. It is the only
deployment-specific domain in any template. It now ships empty, and the
gateway warns when it provisions an account without one, since a blank
sign-in link is otherwise visible only to the customer who receives it.

Extract the remote client from the command body while here. The signing,
request shape and error decoding are the part a Cloudflare Worker
mirrors, and as a function they are testable against a TLS test server
rather than only by hand against a live cluster.

* refactor: drop console_url from signup and default max_accounts to 128

The gateway never read console_url — it passed the value straight through to
the response, and the idempotency record froze it for 24 hours so a corrected
typo still replayed stale. The client that made the request already knows
where it wants to send the new tenant.

max_accounts is now a pointer in the parsed config so an absent [signup]
section takes the 128 default while an explicit 0 still means uncapped.

* feat: run the predastore fault-injection harness as cell-24

Cell-23 asks how fast predastore is when every node is healthy; cell-24 asks
whether it survives one that is not. It runs after cell-23 rather than beside
it: both want a quiet single runner, and a benchmark sharing a machine with a
fault injection run measures the wrong thing.

The port offset keeps the two clear of each other even so, and the job clears
stale nodes on entry and exit, since a run killed before its cleanup trap
leaves one holding ports that fail the next run somewhere unrelated.

* ci: keep the throughput benchmark's output with its results

The run log only existed in the job log, so the artifact it uploaded could not
be read without going back to the run that produced it.

* ci: keep the fault-injection run log with its results

events.txt carries the timeline and the FAIL line, but not the build output or
anything Warp wrote before the harness took over, so a failed cell could only
be read from the job log it was printed into.

* fix: serve the cluster region to the console instead of hardcoding it

The console hardcoded ap-southeast-2 as its SigV4 region in seven files, so on
any other cluster the credential scope was wrong and the gateway rejected every
signed request.

The SPA is embedded in the binary, so a build-time value would pin one binary to
one region. The UI server now serves GET /api/config with the region, no-store
so a proxy fronting several clusters cannot serve one the other's region, and
the SPA loads it once before render.

The region comes from the serving node's config because awsgw pins signature
verification to that same field. Reading the cluster-wide [aws] region instead
would let a cluster whose two keys disagree pass review and still fail to
authenticate.

Also relabels the login card as Spinifex credentials, since the fields are not
AWS ones, and hides the CA install banner unless the console is reached
directly: behind a proxy with a publicly trusted certificate there is nothing
for the cluster CA to fix.

* fix: say once when the host firewall will not be maintained

Both quiet outcomes of the reconcile — no cluster config, and the policy
switched off — return nil without logging, so a node that never arms is
indistinguishable in the journal from one that armed on its first pass.

* test: arm the host firewall before asserting on its peer set

Only the ISO install arms the policy; every other path writes off to the
mode file, so the daemon disables the firewall and never writes a peer
set. The test read that file as its baseline, which it could never have.

It now switches the mode on for its own duration and puts it back, waits
for the peer set the way install-node.sh does, and on failure reports the
mode, the node count and what the daemon said rather than just the
missing file.

* test: move the console region test to the external cmd package

It was in package cmd, which test-package-check rejects, so preflight
failed on the branch. The hook follows the pattern already in
export_test.go.

* test: make the reboot EIP diagnostic capable of naming the drop

The two ofproto/trace probes injected packets with no TTL, so OVN's router
killed them at lr_in_ip_input and both traces ended early for a reason that
had nothing to do with the failure under investigation. A keyword filter then
stripped the table-match lines, hiding where each trace stopped.

Traces now carry a TTL and are kept whole, the real datapath megaflows for the
guest reply are dumped alongside them, and any drop matching the guest source
is resolved from its OpenFlow cookie back to the Southbound logical flow that
installed it.

* fix: exempt an EIP instance from the subnet drop gate with allow, not reroute

A subnet with no route of its own carries a priority-1100 drop policy, and an
instance with an external IP is lifted above it by a priority-1200 policy. That
policy rerouted to the pool gateway, which in distributed NAT is outside every
logical router port subnet, because the gateway LRP is the link-local /30. The
static default route survives that by naming an output port; a routing policy
has no such field, so ovn-northd discarded all three of them and the drop gate
below swallowed everything the instances sent.

The effect was that every external IP answered inbound traffic and none of it
came back: the SYN reached the guest, the guest replied, and the reply died in
the router's policy stage. Guest-initiated egress was lost the same way.

The policy only ever needed to lift the gate. The router's default route already
points at the gateway, so allow leaves the routing decision intact and gives
northd nothing to reject.

* test: match the log the firewall quorum gate actually emits

The assertion waited for "chassis encap addresses; not writing a partial peer
set", which no code has ever logged. The reconcile reports a short chassis list
as "OVN reports N of M chassis encap addresses" and the maintain loop carries
that into its retry warning, so the wait could only ever time out.

Arming the node in the previous commit got the test as far as this assertion for
the first time, which is why it surfaced now. The failure also prints the
journal tail and the same inputs the earlier wait reports.

* fix: stop one unreadable volume document failing every volume listing

A single volume document whose shards no longer reconstruct made
DescribeVolumes, DescribeVolumeStatus and DescribeVolumesModifications
fail for every account, because the listing returned the first fetch
error rather than skipping the document.

ListVolumes now skips a document it cannot read or decode and logs the
skip, mirroring ListAMIs. Callers whose answer would be wrong rather
than merely partial take ListVolumesStrict: the orphan scan and the
snapshot in-use check both gate destructive work on a complete list.

The tolerance covers fetch failures as well as decode failures. An
object whose shards no longer join is as unusable as one whose bytes
will not parse, and it was the fetch path that took the cluster down.

Josh Siviour f647b635b2 feat: pull Ochre model weights from a hub into predastore (#798)
* feat: pull Ochre model weights from a hub into predastore

Add `spx admin ochre weights pull`: fetch a self-host model's weights from
Hugging Face directly into predastore, producing a prefix `weights stage`
consumes. Streams safetensors-only artefacts (plus config/tokenizer and the
shard index), refusing pickle/.bin. Pins an immutable commit SHA, writes an
ochre-pull.json manifest that stage records as SourceRevision, and aborts clean
(removing any written object) on a gated or mid-stream failure. Token resolves
from --hf-token, HF_TOKEN, or a stored platform credential; never logged.

Also add `spx admin ochre credentials set` to store an encrypted provider
credential from stdin, and SourceRevision on the weights KV record + list.

* fix: stream hub downloads without a whole-request timeout

http.Client.Timeout bounds the entire request including the body read,
so a multi-GB safetensors shard was guillotined mid-download at 30s. Bound
dial and response-header latency via the transport instead, leaving the
body free to stream for as long as the server keeps sending.
