#835: inside one driver namespace, a secret:<ns>/<X>/... reference whose first
segment names ANOTHER existing same-type driver instance (id or name,
case-insensitive; another-instance match beats an own-name match, so renaming
one's driver after a victim's unlocks nothing) is refused at save
(DriverConfigSaveGate.ValidateAsync), deploy (CredentialReferenceOtherInstance,
Heidenhain included), Test Connect (TestDriverConnect.DriverInstanceId, ConfigDb
read off the mailbox) and live browse (BrowserSessionService, fail-closed without
a ConfigDb). One rule: DriverCredentialPolicy.DescribeOtherInstanceProblems +
DriverInstanceIdentities. Shared names and the driver's own id stay valid; env:
is not instance-scoped. Running drivers are unchanged (warn-only window: the
deploy gate and the upgrade preflight / /raw banner list them).
#836: OpcUaClient UserCertificatePath is a relative path inside
Drivers:OpcUaClient:UserCertificateDirectory (default
<LocalAppData>/OtOpcUa/pki/user-certificates). Syntactic rule (CredentialFilePaths,
a DriverCredentialPolicy path field) at every #815 seam; at load time
ResolveSecretRefsAsync joins, canonicalises and requires lexical AND
link-resolved containment before the PFX password is resolved, and
LoadCertificate refuses an unresolved path. A running driver's pre-#836 absolute
path keeps loading with a rate-limited warning (LegacyCredentialReferenceTracker.ReportPath).

Live gate against the cppagent 2.7 fixture: count=16384 with bufferSize
16384 streams; 16385 is OUT_OF_RANGE ('count' must be less than 16385).
Warn only when SampleCount > bufferSize, pin both sides of the edge
against the live Agent, and correct the #804 wording that said 'at or
above'.
Parse the /probe Header bufferSize; MTConnectDriverProbe reads sampleCount
(default 1000) and answers Ok with a WARNING message (amber chip in the
Test Connect button); InitializeAsync logs the same Warning and exposes
agentBufferSize on the diagnostics bag. Live-checked against the shared
cppagent fixture (bufferSize 16384).
I1: /hosts eviction keyed off the AUTHORED DriverInstances, so a driver
deleted in /raw but not yet deployed - still running, still publishing -
vanished every tick. The stores' sweep is now EvictUnconfiguredStale(set,
olderThanUtc): an entry goes only when unconfigured AND its PublishedUtc is
older than 60 s. Tests cover unconfigured+fresh kept (positive control),
unconfigured+stale evicted, configured+stale kept, and the deploy hand-off.
M1: Test Connect falls back to the driver's documented ProbeTimeoutSeconds
default (Galaxy 30, OpcUaClient 15, ...) when the key is absent.
M2: the budget never undercuts the config's root timeoutMs (+1 s).
M5: RawBrowseModal compares the open generation captured before the await,
so a close-then-reopen mid-open closes the stale session.
M6: /alarms-historian keeps a 30 s re-poll on 'not registered' (a driver
node may still be starting) instead of stopping for good.
M7: /scripts source fetch failure shows in the dialog, not the error boundary.
M8: the export modal maps only its preview rows; the endpoint writes via
Results.Text (no second byte[] copy).
M9: /hosts config queries are ordered, so SequenceEqual change detection holds.
N1 tooltip, N2 CRLF-safe regex, N3 throttled Warning for subscriber faults,
N5 equipment-import help text now describes RFC 4180 quoting.
H3: MonacoEditor documents that themes are page-global.

DriverTestConnectButton always sent a fixed 10 s, and the Galaxy/OpcUaClient
probes run under min(caller, configured), so ProbeTimeoutSeconds - documented
on every driver as the Test Connect timeout - could shorten a probe but never
lengthen it (Galaxy's 30 s default was silently 10 s). TestConnectBudget reads
the root ProbeTimeoutSeconds from the merged config at click time, clamped to
the actor's [1, 60] s, falling back to TimeoutSeconds. DeviceModal (the only
host) needs no change. The Galaxy/OpcUaClient form hints are reworded.
The 30 s result-clear timer moves from System.Timers.Timer + an async void
Elapsed lambda to System.Threading.Timer, drained in DisposeAsync, with a
generation so a superseded fire cannot clear a newer result.

- AdminProbeService routes TestDriverConnect through
IAdminOperationsClient with a 65s outer guard (actor side already
clamps to [1,60]).
- Added generic AskAsync<T> to IAdminOperationsClient interface and
AdminOperationsClient impl, delegating straight to the Akka proxy.
- DriverTestConnectButton renders the button + inline result chip,
auto-clears after 30s, disables during in-flight.
- Wired into all 9 typed driver pages directly under the
identity section. Sources timeout from the form's
ProbeTimeoutSeconds; sources config JSON from the form's
current Options (operator can test BEFORE saving).
