Docker/nat/docker-compose.yml (stack /opt/otopcua-opcuaclient-nat on 10.100.0.35,
project: lmxopcua label): opc-plc 2.14.10 advertising --ph=otopcua-opc-plc-nat-private.invalid
on internal 50000, published on 50010, so every advertised URL is unreachable on host AND
port. Deployed; NatPublishedEndpointBrowseTests 3/3 against opc.tcp://10.100.0.35:50010
(and the secure case positive once, with the fixture cert temporarily trusted).
CI: integration-fixtures.sh starts a throwaway otopcua-ci-opcplc-nat (50110->50000) and
exports OPCUA_NAT_ENDPOINT; v2-e2e.yml points it at the shared stack. infra/README.md,
scripts/ci/README.md and the fixture README document it.
Scripted condition NodeIds are opaque ScriptedAlarmIds, so splitting them as a
topology path could never match an Equipment grant: a narrow equipment grant was
denied while a Cluster grant passed.
- OtOpcUaNodeManager binds each LIVE scripted condition instance to the
EquipmentId it was materialised under (only when it hangs under that folder);
dropped on remove / drop-recreate / equipment-subtree removal / rebuild; a
same-id re-materialise under another equipment re-parents and re-binds.
- DataPlaneAuthoritySnapshot carries EquipmentScopePaths (EquipmentId ->
[uns, Area, Line, Equipment]) decoded from the artifact by the same
AclScopePathResolver call that plants Equipment grants.
- DataPlaneAuthorizer.AuthorizeScriptedCondition re-reads key, grant and
generation per call (uncached) and evaluates at the owner path; unbound,
replaced or unplaceable owners deny under every grant. No id-split or
realm-root fallback.
- Native conditions (RawPath) and the ACL-off role gate are unchanged.
NodeIds and AlarmCommand.AlarmId are unchanged.
Sdk2OpaqueScriptedScopeBaselineTests deliberately flipped: it pinned the denial
and now pins owner-grant allow / sibling deny / cluster allow. Follow-up #808
(folder ids + Server-object event visibility for narrow UNS grants).
Owner decisions §14 #5/#6 as built (design §12.5):
- Scripting:Worker:Identity (default unset, Windows only, fail-closed validation): each worker
starts under a restricted token derived from the host's. Every privilege but SeChangeNotify is
removed; the restricting SIDs are NT SERVICE\OtOpcUaScriptWorker's SID + Everyone + Users +
RESTRICTED; the token and default DACLs are host + SYSTEM + identity + RESTRICTED. The worker
is created suspended, put in its Job Object before it runs, inherits only its stdio pipes, gets
an ACL'd work dir as TEMP, and runs with DOTNET_EnableDiagnostics=0. The identity is granted on
the host's window station and desktop, because USER32 init made coreclr.dll fail with
ERROR_DLL_INIT_FAILED on windev. The logon SID is not used because the host's process DACL
gives it PROCESS_VM_READ.
- The worker pipe on Windows always has an explicit protected DACL: host account + identity
only. There is no owner ACE, so an elevated host's Administrators gets no access.
- The worker treats access denied on its parent-pid poll as alive; the Job Object covers that case.
- scripts/install/Install-ScriptWorkerIsolation.ps1 + ScriptWorkerIsolation.psm1 are idempotent
and support -WhatIf, -Uninstall and -PlanOnly. They create the disabled anchor service, the
PeCacheDir ACL (protected, no Users, key and markers host-only, pe\ Modify for the identity),
read+execute on script-worker\, a ReadData deny on the install root, the outbound firewall
block on the worker exe, and optionally the host-service env.
- Tests: the dry-run harness scripts/install/tests/Test-ScriptWorkerIsolation.ps1 (46
assertions, mutation-checked); ScriptWorkerIdentityTests; WorkerIsolationTests, which cover
the pipe ACL, token access and a real restricted worker running a script, all green on windev.

v2-integration.yml runs the Sql, Historian.SqlServer, Historian.QuestDb and OpcUaClient
integration projects against throwaway SQL Server/PostgreSQL/QuestDB/opc-plc containers
started by scripts/ci/integration-fixtures.sh, with a MIN_EXECUTED=440 floor. v2-e2e.yml is
manual/weekly, probes the shared fleet and skips cleanly when unreachable. v2-ci.yml is
functionally unchanged. Unverified on a hosted runner until first run.

Run 959 (job 3552) was silent from 13:39 for 3h12m and was failed by the server
reaper with no cause. Pre-#707 runs 935/938/941/942/947/959 all ended at 189-193 min;
no run since 76bdca90 exceeds 82 min (healthy ~53). Adds timeout-minutes 120 and
blame-hang (20m, no dump) to the whole-solution test step.
