ACL design defines NodePermissions bitmask flags covering Browse / Read / Subscribe / HistoryRead / WriteOperate / WriteTune / WriteConfigure / AlarmRead / AlarmAcknowledge / AlarmConfirm / AlarmShelve / MethodCall plus common bundles (ReadOnly / Operator / Engineer / Admin); 6-level scope hierarchy (Cluster / Namespace / UnsArea / UnsLine / Equipment / Tag) with default-deny + additive grants and Browse-implication on ancestors; per-LDAP-group grants in a new generation-versioned NodeAcl table edited via the same draft → diff → publish → rollback boundary as every other content table; per-session permission-trie evaluator with O(depth × group-count) cost cached for the lifetime of the session and rebuilt on generation-apply or LDAP group cache expiry; cluster-create workflow seeds a default ACL set matching the v1 LmxOpcUa LDAP-role-to-permission map for v1 → v2 consumer migration parity; Admin UI ACL tab with two views (by LDAP group, by scope), bulk-grant flow, and permission simulator that lets operators preview "as user X" effective permissions across the cluster's UNS tree before publishing; explicit Deny deferred to v2.1 since verbose grants suffice at v2.0 fleet sizes; only denied OPC UA operations are audit-logged (not allowed ones — would dwarf the audit log). Schema doc gains the NodeAcl table with cross-cluster invariant enforcement and same-generation FK validation; admin-ui.md gains the ACLs tab; phase-1 doc gains Task E.9 wiring this through Stream E plus a NodeAcl entry in Task B.1's DbContext list.
Dev-environment doc inventories every external resource the v2 build needs across two tiers per decision #99 — inner-loop (in-process simulators on developer machines: SQL Server local or container, GLAuth at C:\publish\glauth\, local dev Galaxy) and integration (one dedicated Windows host with Docker Desktop on WSL2 backend so TwinCAT XAR VM can run in Hyper-V alongside containerized oitc/modbus-server, plus WSL2-hosted Snap7 and ab_server, plus OPC Foundation reference server, plus FOCAS TestStub and FaultShim) — with concrete container images, ports, default dev credentials (clearly marked dev-only since production uses Integrated Security / gMSA per decision #46), bootstrap order for both tiers, network topology diagram, test data seed locations, and operational risks (TwinCAT trial expiry automation, Docker pricing, integration host SPOF mitigation, per-developer GLAuth config sync, Aveva license scoping that keeps Galaxy tests on developer machines and off the shared host).
Removes consumer cutover (ScadaBridge / Ignition / System Platform IO) from OtOpcUa v2 scope per decision #136 — owned by a separate integration / operations team, tracked in 3-year-plan handoff §"Rollout Posture" and corrections §C5; OtOpcUa team's scope ends at Phase 5. Updates implementation/overview.md phase index to drop the "6+" row and add an explicit "OUT of v2 scope" callout; updates phase-1 and phase-2 docs to reframe cutover as integration-team-owned rather than future-phase numbered.
Decisions #129–137 added: ACL model (#129), NodeAcl generation-versioned (#130), v1-compatibility seed (#131), denied-only audit logging (#132), two-tier dev environment (#133), Docker WSL2 backend for TwinCAT VM coexistence (#134), TwinCAT VM centrally managed / Galaxy on dev machines only (#135), cutover out of v2 scope (#136), dev credentials documented openly (#137).

Add Phase 2 detailed implementation plan (docs/v2/implementation/phase-2-galaxy-out-of-process.md) covering the largest refactor phase — moving Galaxy from the legacy in-process OtOpcUa.Host project into the Tier C out-of-process topology specified in driver-stability.md. Five work streams: A. Driver.Galaxy.Shared (.NET Standard 2.0 IPC contracts using MessagePack with hello-message version negotiation), B. Driver.Galaxy.Host (.NET 4.8 x86 separate Windows service that owns MxAccessBridge / GalaxyRepository / alarm tracking / GalaxyRuntimeProbeManager / Wonderware Historian SDK / STA thread + Win32 message pump with health probe / MxAccessHandle SafeHandle for COM lifetime / subscription registry with cross-host quality scoping / named-pipe IPC server with mandatory ACL + caller SID verification + per-process shared secret / memory watchdog with Galaxy-specific 1.5x baseline + 200MB floor + 1.5GB ceiling / recycle policy with 15s grace + WM_QUIT escalation to hard-exit / post-mortem MMF writer / Driver.Galaxy.FaultShim test-only assembly), C. Driver.Galaxy.Proxy (.NET 10 in-process driver implementing every capability interface, heartbeat sender on dedicated channel with 2s/3-miss tolerance, supervisor with respawn-with-backoff and crash-loop circuit breaker with escalating cooldown 1h/4h/24h, address space build via IAddressSpaceBuilder producing byte-equivalent v1 output), D. Retire legacy OtOpcUa.Host (delete from solution, two-service Windows installer, migrate appsettings.json Galaxy sections to central DB DriverConfig blob), E. Parity validation (v1 IntegrationTests pass count = baseline failures = 0, scripted Client.CLI walkthrough output diff vs v1 only differs in timestamps/latency, four named regression tests for the 2026-04-13 stability findings). Compliance script verifies all eight Tier C cross-cutting protections have named passing tests. Decision #128 captures the survey-removal; cross-references added to plan.md Reference Documents and overview.md phase index.

The aahClientManaged SDK is now isolated in ZB.MOM.WW.LmxOpcUa.Historian.Aveva and loaded via HistorianPluginLoader from a Historian/ subfolder only when enabled, removing the SDK from Host's compile-time and deploy-time surface.

Move subscribe/unsubscribe I/O outside lock(Lock) in SyncAddressSpace to avoid
blocking all OPC UA operations during rebuilds. Replace blocking ReadAsync calls
for alarm priority/description in dispatch loop with cached subscription values.
Extract IHistorianConnectionFactory so EnsureConnected can be tested without the
SDK runtime — adds 5 connection lifecycle tests (failure, timeout, reconnect,
state resilience, dispose-after-failure). All stability review findings and test
coverage gaps are now fully resolved.

Add ServerCapabilities/OperationLimits node, enable diagnostics, add OnModifyMonitoredItemsComplete
override for DA compliance. Wire shelving, enable/disable, confirm, and addcomment handlers on
alarm conditions with LocalTime/Quality event fields for Part 9 compliance. Add Aes128/Aes256
security profiles, X.509 certificate authentication, and AUDIT-prefixed auth logging. Fix flaky
probe monitor test. Update docs for all changes.

Replace direct SQL queries against Historian Runtime database with the Wonderware
Historian managed SDK (ArchestrA.HistorianAccess). Add HistoryServerCapabilities node,
AggregateFunctions folder, continuation points, ReadAtTime interpolation, ReturnBounds,
ReadModified rejection, HistoricalDataConfiguration per node, historical event access,
and client-side StandardDeviation aggregate support. Remove screenshot tests.

Prerequisites, build commands, and test instructions are now split by target
framework since the server requires AVEVA/COM/Windows while the clients are
cross-platform.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Major changes across the client stack:
- Settings persistence (connection, subscriptions, alarm source)
- Deferred OPC UA SDK init for instant startup
- Array/status code formatting, write value popup, alarm acknowledgment
- Severity-colored alarm rows, condition dedup on server side
- DateTimeRangePicker control with preset buttons and UTC text input
- Historian queries use wwTimezone=UTC and OPCQuality column
- Recursive subscribe from tree, multi-select remove
- Connection panel with expander, folder chooser for cert path
- Dynamic tab headers showing subscription/alarm counts
- Client.UI.md documentation with headless-rendered screenshots

The standalone CLI tool is superseded by src/ZB.MOM.WW.LmxOpcUa.Client.CLI
which uses the shared IOpcUaClientService abstraction. Renames CliTool.md to
Client.CLI.md and updates README, CLAUDE.md, Security, and Redundancy docs.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
CliTool.md now documents the new Client.CLI project (shared service
abstraction, all 8 commands, verbose logging) instead of the standalone
tools/opcuacli-dotnet tool.

Right-click on browse tree nodes to Subscribe (multi-select) or View History
(Variable nodes only), with automatic tab switching. Add missing UI controls
for failover URLs, session timeout, auto-accept certificates, and certificate
store path. Fix tree expansion by adding two-way IsExpanded binding on
TreeViewItem.

Implements Client.Shared (IOpcUaClientService with connection lifecycle, failover,
browse, read/write, subscriptions, alarms, history, redundancy), Client.CLI (8 CliFx
commands mirroring tools/opcuacli-dotnet), and Client.UI (Avalonia desktop app with
tree browser, read/write, subscriptions, alarms, and history tabs). All three target
.NET 10 and are covered by 249 unit tests.

Map LDAP groups to custom OPC UA role NodeIds on RoleBasedIdentity.GrantedRoleIds
during authentication, replacing the username-to-role side cache. Split ReadWrite
into WriteOperate/WriteTune/WriteConfigure so write access is gated per Galaxy
security classification. AnonymousCanWrite now behaves consistently regardless
of LDAP state.

Previously alarms were only reported to the immediate parent node and the Server node.
Now ReportEventUpNotifierChain walks the full parent chain so clients subscribed at
TestArea see alarms from TestMachine_001, and EventNotifier is set on all ancestors
of alarm-containing nodes.

- Remove ConfigUserAuthenticationProvider and Users property — LDAP is the only auth mechanism
- Fix historian quality mapping to use existing QualityMapper (OPC DA quality bytes, not custom mapping)
- Add AppRoles constants, unify HasWritePermission/HasAlarmAckPermission into shared HasRole helper
- Hoist write permission check out of per-item loop, eliminate redundant _ldapRolesEnabled field
- Update docs (Configuration.md, Security.md, OpcUaServer.md, HistoricalDataAccess.md)

Replace static user list with GLAuth LDAP authentication. Group
membership (ReadOnly, ReadWrite, AlarmAck) maps to granular OPC UA
permissions for write and alarm-ack operations. Anonymous can still
browse and read but not write.

Enhance /api/health with component-level health, ServiceLevel, and
redundancy state for load balancer probes. Add /health HTML page for
operators to monitor node health in clustered System Platform deployments.

Shows mode, role, ServiceLevel, ApplicationUri, and redundant server
set when redundancy is enabled. Primary renders with a green border,
secondary with yellow. Also included in the JSON API response.

All commands gain --failover-urls (-F) to specify alternate endpoints.
Short-lived commands try each URL in order on initial connect. The
subscribe command monitors KeepAlive and automatically reconnects to
the next available server, re-creating the subscription on failover.
Verified with live service start/stop: primary down triggers failover
to secondary, primary restart allows failback.

Separates ApplicationUri from namespace identity so each instance in a
redundant pair has a unique server URI while sharing the same Galaxy
namespace. Exposes RedundancySupport, ServerUriArray, and dynamic
ServiceLevel through the standard OPC UA server object. ServiceLevel
is computed from role (Primary/Secondary) and runtime health (MXAccess
and DB connectivity). Adds CLI redundancy command, second deployed
service instance, and 31 new tests including paired-server integration.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Covers non-transparent warm/hot redundancy with configurable roles,
dynamic ServiceLevel, CLI support, second service instance deployment,
and verification guardrails across unit, integration, and manual tests.

Adds Security section to appsettings.json with configurable OPC UA
transport profiles (None, Basic256Sha256-Sign, Basic256Sha256-SignAndEncrypt),
certificate policy settings, and a configurable BindAddress for the
OPC UA endpoint. Defaults preserve backward compatibility.

Implements configurable user authentication (anonymous + username/password)
with pluggable credential provider (IUserAuthenticationProvider). Anonymous
writes can be disabled via AnonymousCanWrite setting while reads remain
open. Adds -U/-P flags to all CLI commands for authenticated sessions.

Set a new EventId (GUID) on AlarmConditionState each time an alarm event
is reported so the framework can match it when clients call Acknowledge.
Without this, the framework rejected all ack attempts with BadEventIdUnknown.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Adds alarm_ack.md documenting the two-way acknowledge flow (OPC UA client
writes AckMsg, Galaxy confirms via Acked data change). Includes external
code review fixes for subscriptions and node manager, and removes stale
plan files now superseded by component documentation.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
Removes Security Classification, Alarm Tracking, Historical Data Access,
Incremental Sync, Configuration, Data Type Mapping, and Startup Sequence
sections that are now covered by their respective docs/ files.
