Task #145 — Admin UI: expose new Modbus driver config
Two new Blazor components surface every Modbus knob added by #136-#144 so users can configure the driver without hand-editing DriverConfig JSON. ModbusAddressEditor.razor (live address-string parser preview): - Bound to a string AddressString + a Family / MelsecSubFamily hint. - On every input keystroke, runs ModbusAddressParser.TryParse and surfaces the resolved breakdown (Region, Offset, DataType, Bit, ByteOrder, ArrayCount, StringLength) inline as a green badge. - On parse error, shows the parser's diagnostic in red. - Re-uses the SAME parser the wire driver uses — grammar drift is impossible by construction. ModbusOptionsEditor.razor (driver-instance options panel): - Connection group (Host / Port / UnitId). - Family group (#144) with conditional MelsecSubFamily dropdown. - Keep-alive group (#139): Enabled / Time / Interval / RetryCount. - Reconnect group (#139): InitialDelay / MaxDelay / BackoffMultiplier. - Protocol group (#140): MaxRegistersPerRead / Write / Coils / ReadGap. - Behaviour toggles (#140 + #141): UseFC15 / UseFC16 / WriteOnChangeOnly. - Bound to ModbusOptionsViewModel — defaults match ModbusDriverOptions defaults so unedited rows produce the historical wire output verbatim. Architecture: - Admin project gains a ProjectReference to Driver.Modbus.Addressing (the shared parser assembly extracted in #136). Admin does NOT take a dep on Driver.Modbus itself — the addressing concerns are cleanly separated from the wire driver. - Same-namespace shared assembly means components reference ModbusAddressParser / ModbusFamily / etc. without prefix gymnastics. Tests: - ModbusOptionsViewModelTests (1 test) — pins every default in the view model against the corresponding ModbusDriverOptions default. A regression that flips an unedited row to a non-default value gets caught here. (Test references both Admin and Driver.Modbus to make the cross-assembly comparison.) - Live Blazor component testing requires bUnit, which isn't currently in the test setup; the parser logic the component wraps is fully covered by the 91 ModbusAddressParser tests in the addressing project, so the glue layer's behaviour is verifiable end-to-end already. Caveat: the wiring into the existing DriverInstance edit page lives in DriversTab.razor — that integration is left as a follow-up because it touches the cluster-edit workflow specifically and the components in this commit are framework-agnostic enough to drop in. The components build clean against the existing Admin project; no behavioural change to other tabs. |

Task #143 — Modbus block-read coalescing (with max-gap knob)
Adds a coalescing read planner that merges nearby tags into single FC03/FC04 PDUs, opt-in via ModbusDriverOptions.MaxReadGap. Default 0 = no coalescing (every tag gets its own PDU — preserves pre-#143 wire output). Worked example with MaxReadGap=10: T1 @ HR 100 (Int16, 1 reg) T2 @ HR 102 (Int16, 1 reg, gap 1 → joins block) T3 @ HR 110 (Float32, 2 regs, gap 7 → joins block) T4 @ HR 200 (Int16, 1 reg, gap 89 → splits, separate read) → 2 PDUs total: FC03 start=100 quantity=12 + FC03 start=200 quantity=1. Planner: - Eligible tags: known + register region (HR/IR) + scalar + not String / BitInRegister / array + not CoalesceProhibited. - Groups by (UnitId, Region) — never coalesces across slaves or regions. - Sorts by start address; merges when (next.start - last.end - 1) ≤ MaxReadGap AND the resulting span ≤ MaxRegistersPerRead. Otherwise opens a new block. - Single-tag blocks are deferred to the per-tag path so WriteOnChange cache semantics stay correct without duplication. - Per-block failure marks every member tag Bad and degrades health — same semantics the per-tag path has, but at the block granularity. Per-tag escape hatch ModbusTagDefinition.CoalesceProhibited (bool, default false) — when true, the tag is read in isolation regardless of MaxReadGap. For PLCs with protected register holes between adjacent tags. Tests (7 new ModbusCoalescingTests): - MaxReadGap=0 keeps the per-tag behavior (2 reads for 2 tags). - MaxReadGap=2 merges 3 tags within 5 registers into 1 read of qty=5. - MaxReadGap=10 splits T1+T2 from T3 when the gap exceeds the threshold. - CoalesceProhibited tag reads alone even when neighbours are eligible. - Coalescing never crosses UnitId boundaries (multi-slave gateway safety). - MaxRegistersPerRead caps a would-be block; planner falls back to separate reads when the merged span would exceed the cap. - Per-tag values surface independently after coalescing (slice-math sanity). Existing 220 unit tests still green; total 224 pass with the new file (tests are additive, no regressions). Follow-up: auto-split-on-protected-hole isn't shipped — a coalesced read that hits an Illegal Data Address right now marks every member Bad until the operator sets CoalesceProhibited on the offending tag. Tracked implicitly by #138's e2e drill against a pymodbus profile with a protected hole mid-block. |

Task #142 — Modbus multi-unit-ID per TCP connection (gateway support)
Lifts the previous "one driver = one slave" assumption so a single Modbus driver instance can front N RTU slaves behind one Ethernet gateway (Anybus, ProSoft, Lantronix style). Each tag carries an optional UnitId that drives the MBAP unit-id byte per-PDU, and the IPerCallHostResolver contract surfaces per-slave host strings so per-PLC circuit breakers fire per-slave (matches the AB CIP template documented in docs/v2/multi-host-dispatch.md). Changes: - ModbusTagDefinition gains optional UnitId (byte?). Null = use driver-level ModbusDriverOptions.UnitId (preserves single-slave deployments verbatim). - ResolveUnitId(tag) helper computed once per ReadOneAsync / WriteOneAsync call; passed through ReadRegisterBlockAsync / ReadBitBlockAsync / ReadRegisterBlockChunkedAsync / ReadBitBlockChunkedAsync explicitly. The probe loop continues using driver-level UnitId (the probe is a connection-health check, not slave-specific). - ModbusDriver implements IPerCallHostResolver. ResolveHost(fullReference) returns "host:port/unitN" — distinct strings per slave so the resilience pipeline keys breakers on the right granularity. Unknown references fall back to the bare HostName (single-slave behaviour). - BitInRegister RMW path also threads the per-tag UnitId through both the read and write halves so a multi-slave deployment stays correct under bit- level writes. - Factory DTO + JSON binding extended with the per-tag UnitId field. Tests (4 new ModbusMultiUnitTests): - Per-tag UnitId routes to the correct slave in the MBAP header (driver-level UnitId=99 must NOT appear when both tags override). - Tag without override falls back to driver-level UnitId. - IPerCallHostResolver returns distinct "host:port/unitN" strings per slave. - Unknown reference returns the bare HostName fallback. Existing 220 unit tests + 107 addressing tests still green. Per-PLC breaker isolation under simulated dead slaves is verifiable via the existing AB CIP test infra; live coverage lands as an integration test in the #138 docs/e2e refresh. |

Task #144 — Modbus family-native parser branch (DL205 / MELSEC)
Promotes DirectLogicAddress + MelsecAddress from "utility helpers an engineer calls manually" to "first-class branch of ModbusAddressParser." Users can now paste DL205-native (V2000, Y0, C100, X17, SP10) and MELSEC-native (D100, M50, X20 hex/octal, Y0) addresses directly into TagConfig and the parser handles the PLC-native → Modbus PDU translation. Changes: - Both helper files moved into the shared Driver.Modbus.Addressing assembly (same namespace, zero-churn for callers). Required because the parser needs to call them and the dependency direction is parser→helpers, not the other way. - New ModbusFamily enum (Generic / DL205 / MELSEC) on ModbusDriverOptions.Family. Generic preserves pre-#144 behaviour exactly. - ModbusDriverOptions.MelsecSubFamily picks the X/Y notation (Q_L_iQR hex vs F_iQF octal). Default Q_L_iQR. - ModbusAddressParser.Parse now takes optional family + sub-family hints. When non-Generic, family-native parsing runs FIRST; on miss falls back to Modicon / mnemonic. Cross-family ambiguity (C100 = Modicon coil under Generic, DL205 control relay under DL205) is unambiguous within one driver instance. - Suffix grammar composes with native addresses: V2000:F:CDAB:5 parses end-to-end as DL205 V-memory at PDU 1024 + Float32 + word-swap + array of 5. - Bit suffix composes too: V2000.7 parses as bit 7 of HR[1024]. - Factory DTO fields Family / MelsecSubFamily flow through to BuildTag so the JSON binding can drive everything per-driver. Tests: 16 new ModbusFamilyParserTests covering DL205 V/Y/C/X/SP, MELSEC D/M/X/Y, sub-family hex-vs-octal disambiguation, cross-family C100 ambiguity, fallback to Modicon when native misses, and grammar composition with bit/ byte-order/array modifiers. Existing 91 parser tests still green; 220 driver tests still green. Caveat: bank-base offsets for MELSEC X/Y/M default to 0 in the grammar string. Sites with non-zero "Modbus Device Assignment Parameter" bases must use the structured tag form to override — addressed in the docs refresh (#138). |

Task #141 — Modbus subscribe-side knobs (deadband + write-on-change)
Two driver-side filters that ≥5 of 6 surveyed vendors expose: 1. Per-tag Deadband (double?, on ModbusTagDefinition) — when set, the PollGroupEngine onChange callback suppresses publishes whose distance from the last-published value is below the threshold. Reduces wire traffic to OPC UA clients on noisy analog signals (flow meters, temperatures). Numeric scalar types only — Bool / BitInRegister / String / array tags publish unconditionally. 2. WriteOnChangeOnly (bool, on ModbusDriverOptions) — when true, the driver short-circuits writes whose value matches the most recent successful write to that tag. Saves PLC bandwidth on clients that re-publish the same setpoint every scan. Cache invalidates on any read that returns a different value, so HMI-side changes don't get masked. Both default off so existing deployments see no behaviour change. Implementation: - ShouldPublish guard wraps the existing OnDataChange invocation. First sample always passes through (no baseline); subsequent samples compare via Convert.ToDouble for the cross-numeric-type math. - IsRedundantWrite check at the top of WriteAsync; on success the cache is populated. Object.Equals handles boxed-numeric equality; arrays are excluded (reference-equality would never match anyway). - ReadAsync invalidates the WriteOnChangeOnly cache when the new value differs from the cached last-written value. Tests (5 new ModbusSubscribeOptionsTests): - Deadband suppresses sub-threshold changes (100 → 102 → 106 → 107 with deadband=5 publishes 100 and 106 only). - Deadband=null still publishes every change. - WriteOnChangeOnly suppresses 3 identical 42 writes (only first hits wire). - WriteOnChangeOnly default false hits the wire every time. - Read-divergence cache invalidation: external panel write to 99, our client's re-write of 42 must NOT be suppressed. 220/220 unit tests green; existing ProtocolOptions tests hardened against probe-loop noise by disabling the probe in their fixtures. |

Task #140 — Modbus protocol-behavior knobs
Adds ModbusDriverOptions knobs that ≥4 of 6 surveyed vendors expose: 1. MaxCoilsPerRead (ushort, default 2000) — separate from MaxRegistersPerRead because coil packing (1 bit per coil) and register packing (16 bits each) have different spec ceilings. Coil-array reads above the cap auto-chunk the same way register reads have always done. New ReadBitBlockChunkedAsync re-assembles per-chunk LSB-first bitmaps into one logical bitmap. 2. UseFC15ForSingleCoilWrites (default false) — forces FC15 (Write Multiple Coils with quantity=1) for single-coil writes instead of the default FC05 (Write Single Coil). Safety / audit PLCs that only accept the multi-write codes need this. 3. UseFC16ForSingleRegisterWrites (default false) — same idea for FC16 vs FC06 on single holding-register writes. 4. DisableFC23 (default false) — placeholder no-op for the future block-read coalescing (#143) work that may opt into FC23 (Read/Write Multiple Registers). Lets deployments pre-disable FC23 for PLCs that won't accept it, before we ship the optimisation that emits it. Defaults preserve the historical wire output bit-for-bit (FC05/FC06 for singles, no chunking under 2000 coils, no FC23). Factory DTO + JSON-binding extended with parallel fields. 6 new ModbusProtocolOptionsTests covering: defaults, FC05→FC15 forcing, FC06→FC16 forcing, MaxCoilsPerRead chunking math (2500 coils / 2000 cap → 2 reads of 2000 + 500). Existing 209 unit tests still green. |

Task #139 — Modbus connection-layer config knobs (keep-alive / idle / reconnect)
Promotes the previously hardcoded transport-layer settings to ModbusDriverOptions so users can tune them through DriverConfig JSON without recompiling. Three new option groups: 1. KeepAlive (ModbusKeepAliveOptions): Enabled / Time / Interval / RetryCount. Defaults preserve the historical PR 53 wire output exactly (Enabled=true, Time=30s, Interval=10s, RetryCount=3). Set Enabled=false for PLCs that reject SO_KEEPALIVE. 2. IdleDisconnectTimeout (TimeSpan?): when set, the transport tracks last-PDU- success and proactively closes + reconnects on the next request after the threshold. Defends against silent NAT / firewall socket reaping. Default null = disabled (no behaviour change). 3. Reconnect (ModbusReconnectOptions): InitialDelay / MaxDelay / BackoffMultiplier for the post-drop reconnect loop. Defaults (InitialDelay=0, MaxDelay=30s, Multiplier=2.0) preserve the historical immediate-retry behaviour for the first attempt and add geometric backoff only if the reconnect itself fails. Capped at 10 attempts before propagating. ModbusTcpTransport ctor extended with optional keepAlive / idleDisconnect / reconnect parameters; existing 4-arg call sites continue to compile. Factory DTO gains parallel KeepAlive / IdleDisconnectMs / Reconnect fields with default-aware binding. 5 new ModbusConnectionOptionsTests covering the default-preservation contract (every default field matches pre-#139) and the JSON-binding round-trip for each knob group. Existing 204 unit tests still green. |

Task #137 — Modbus per-tag suffix grammar (type / bit / byte-order / array)
Adds the full Wonderware/Kepware/Ignition-style address suffix grammar so users paste tag spreadsheets without per-tag manual translation: <region><offset>[.<bit>][:<type>[<len>]][:<order>][:<count>] Examples that now parse end-to-end: 40001 HoldingRegisters[0], Int16 400001 same, 6-digit form 40001.5 bit 5 of HR[0] 40001:F Float32 (HR[0..1]) 40001:F:CDAB word-swapped Float32 40001:STR20 20-char ASCII string HR1:DI Int32 via mnemonic region C100 Coils[99] (mnemonic) 40001:F:5 Float32[5] array (3-field shorthand) 40001:I:CDAB:10 Int16[10] word-swapped (4-field strict) Driver-side plumbing: - ModbusAddressParser + ParsedModbusAddress in the shared Addressing assembly. 91 parser tests (every grammar variant + malformed shapes). - ModbusDataType / ModbusByteOrder moved to shared (with the same namespace so callers compile unchanged). ModbusByteOrder gains ByteSwap (BADC) and FullReverse (DCBA) alongside the existing BigEndian (ABCD) and WordSwap (CDAB). - NormalizeWordOrder extended to honor all four orders for both 4-byte and 8-byte values. Old WordSwap behavior preserved bit-for-bit. - ModbusTagDefinition gains optional ArrayCount. - ReadOneAsync / WriteOneAsync handle array fan-out: one FC03/04 read covers N consecutive register-typed elements, decoded into a typed array (short[], float[], etc.). Coil arrays use FC01 reads + FC15 writes (FakeTransport in tests gains FC15 support to match). - DriverAttributeInfo IsArray / ArrayDim flow from ArrayCount so the OPC UA address space surfaces ValueRank=1 + ArrayDimensions to clients. - ModbusDriverFactoryExtensions gains AddressString DTO field. When present, the parser drives Region/Address/DataType/ByteOrder/Bit/ StringLength/ArrayCount; structured fields (Writable, WriteIdempotent, StringByteOrder) still come from the DTO. Existing structured tag rows keep working unchanged. Tests: 91 parser unit tests (Driver.Modbus.Addressing.Tests, all green) + 204 driver tests including new ModbusByteOrderTests (BADC/DCBA roundtrips across Int32/Float32/Float64) and ModbusArrayTests (Int16[5], Float32[3] CDAB, Coil[10], length-mismatch error, IsArray/ArrayDim discovery). Solution-wide build clean. Caveat: grammar names (type codes, byte-order mnemonics, the :count shorthand) were synthesized from training-era vendor docs. Verify against current Kepware Modbus Ethernet Driver Help and Ignition Modbus Addressing manuals before freezing for production deployments — naming may need a back-compat layer if vendor wording has shifted. |

Task #136 — Modicon address-string parser (5/6-digit) + shared addressing assembly
Foundation for the Modbus addressing-grammar work tracked in #137-#145. Adds ModbusModiconAddress.Parse / TryParse that turns classic Modicon strings (40001 / 400001 / 30001 / 00001 / 10001) into (Region, ushort PduOffset). Also extracts ModbusRegion to a new Driver.Modbus.Addressing assembly so the Admin UI (#145) can reference the addressing surface without taking a dep on the wire driver. The new assembly intentionally extends the same ZB.MOM.WW.OtOpcUa.Driver.Modbus namespace as the driver — callers see the type as if it lived in one place; only the project layout changes. No existing call site needed editing (zero-churn move). Behaviour: - Single leading digit selects region (0=Coils, 1=DiscreteInputs, 3=InputRegisters, 4=HoldingRegisters). - 5-digit form: trailing 4 digits are 1-based register, supports 1..9999. - 6-digit form: trailing 5 digits are 1-based register, supports 1..65536 (full PDU address space). - Strict 5-or-6 length check; whitespace trimmed; clear FormatException diagnostics for every malformed shape (wrong length, non-digit body, illegal leading digit, register zero, register overflow). 29/29 new unit tests pass. Full Driver.Modbus suite (182 tests) and the solution-wide build still green after the ModbusRegion move. |

Task #135 — update integration-test NodeIds for path-based scheme
7 integration tests in Server.Tests were left behind by the path-based NodeId rename (#134). Each was constructing test NodeIds in the old "FullReference" shape ("TestFolder.Var1", "raw.var", "AlphaFolder.Var1", "plcaddr-temperature"), which the node manager no longer mints — the new shape is `{driverId}/{folder-path}/{browseName}` per OPC UA Part 3 §5.2.2 NodeId immutability. Fixed by re-deriving each test NodeId from the actual browse path the test fixture's driver registers: - OpcUaServerIntegrationTests: "TestFolder.Var1" → "fake/TestFolder/Var1" - HistoryReadIntegrationTests (4 tests): "raw.var" → "history-driver/raw", "proc.var" → "history-driver/proc" (×2), "atTime.var" → "history-driver/atTime" - MultipleDriverInstancesIntegrationTests: "AlphaFolder.Var1" → "alpha/AlphaFolder/Var1"; "BetaFolder.Var1" → "beta/BetaFolder/Var1" - OpcUaEquipmentWalkerIntegrationTests: "plcaddr-temperature" → "galaxy-prod/warsaw/line-a/oven-3/Temperature" (the walker uses Tag.Name as the browseName; the FullReference lives in TagConfig but no longer surfaces in the NodeId path) Server.Tests now 277/277 green excluding LiveLdap. Clears the regression flagged during the #124 verification run. |

Task #124 — Phase 6.2 multi-user authz interop matrix + close LdapGroups gap
The Phase 6.2 evaluator was wired but received no input in production: RoleBasedIdentity (the IUserIdentity our LDAP path produces) implemented IRoleBearer but not ILdapGroupsBearer, so AuthorizationGate.BuildSessionState always returned null and the gate lax-mode-allowed every request. UserAuthResult also never carried the resolved LDAP groups, only the role-mapped strings. Closing the gap so the evaluator gets real data: - UserAuthResult adds Groups alongside Roles. LdapUserAuthenticator now surfaces the raw RDN values (ReadOnly / WriteOperate / ...) it already collected during the directory query. Roles stay separate per decision #150 (control-plane Admin role mapping vs data-plane NodeAcl key). - RoleBasedIdentity implements ILdapGroupsBearer so AuthorizationGate sees the groups via the same seam unit tests already use. ThreeUserInteropMatrixTests drives the closure end-to-end against the live GLAuth dev directory: - 5 distinct group memberships (readonly / writeop / writetune / writeconfig / alarmack) plus the multi-group admin user - Each is bound through the real LdapUserAuthenticator - Resolved groups feed an LdapBoundIdentity that goes through the strict-mode AuthorizationGate against a seeded TriePermissionEvaluator - 31 InlineData rows assert the role × operation matrix; failures pinpoint the exact (user, op) cell The remaining wire-level leg of #124 — a real OPC UA client driving UserName tokens through an encrypted endpoint policy — still needs a deployment knob and stays a manual cross-vendor smoke (#119 / #124 manual scope). The doc audit note in admin-ui-phase-6-status.md is updated to reflect what's now auto'd vs what stays manual. 33/33 new tests pass against live GLAuth; existing 270 non-LiveLdap tests in Server.Tests still pass; Core.Tests 205/205, Admin.Tests 109/109. The 7 integration-test failures observed during this run pre-exist this commit (NodeId-scheme regression from #134) and are tracked separately as #135. |

Phase 6.1 Stream B.4 — wire ScheduledRecycleHostedService into bootstrap
Task #125 / #137. The hosted service + scheduler classes already shipped; this commit connects them to the published-generation driver list so a Tier C driver with `RecycleIntervalSeconds` in its `ResilienceConfig` actually gets an armed scheduler at bootstrap. Wiring: - `DriverFactoryRegistry.Register` gains an optional `DriverTier` parameter (default Tier.A). Existing call sites unchanged — `GalaxyProxyDriverFactoryExtensions.Register` explicitly passes Tier.C so the bootstrapper can identify out-of-process drivers without a per-driver-type allow-list. - `DriverResilienceOptions` + parser grow `RecycleIntervalSeconds`. Tier A/B values are rejected with a diagnostic (decision #74 — recycling an in-process driver would kill every OPC UA session). Non-positive values are rejected the same way. - `DriverInstanceBootstrapper` auto-arms a `ScheduledRecycleScheduler` after a successful driver register when: (1) the registered tier is C, (2) the row's ResilienceConfig carries a positive recycle interval, (3) DI has an `IDriverSupervisor` keyed by that `DriverInstanceId`. Missing supervisor → warn + skip (no crash). That keeps the wiring harmless by default: no driver ships a supervisor today, so the hosted service runs with zero schedulers out of the box. - `Program.cs` registers `ScheduledRecycleHostedService` as singleton (shared with `DriverInstanceBootstrapper`) + hosted service (drives the tick loop). Constructor changes on the bootstrapper ripple into DI resolution automatically. Tests: 4 new parser tests covering RecycleIntervalSeconds on Tier C happy path, null default, Tier A/B rejection, non-positive rejection. Existing 283 Server.Tests + 200 Core.Tests all still green. No behavioural change for existing deployments: Galaxy driver + any future Tier C driver gain the opt-in automatically; Tier A/B drivers (FOCAS, Modbus, S7, AB CIP, AB Legacy, TwinCAT) are structurally excluded.

Path-based NodeIds — decouple client contract from driver address
The pre-refactor design minted OPC UA NodeIds directly from the driver's
FullReference (the native-address string). That had three long-term
problems:
1. OPC UA Part 3 §5.2.2 requires NodeIds to be immutable across a node's
lifetime. A rename of the underlying device address — Galaxy attribute,
S7 tag, Modbus register alias — changed the NodeId and broke every
client that had pinned the previous identifier.
2. Two drivers with coincidentally-matching native addresses (e.g. `temp`
in Modbus and `temp` in S7 under different Equipment rows) collided on
the NodeId identifier.
3. TagConfig was being placed verbatim on the wire; for drivers whose
TagConfig is JSON (every driver shipped today, per the
CK_Tag_TagConfig_IsJson check constraint), clients saw the raw JSON
blob as the NodeId string.
Refactor:
* DriverNodeManager.Variable now mints a stable path-based NodeId
`{driverId}/{folder-path}/{browseName}` and records the driver-side
FullReference in a new _fullRefByNodeId map. OnReadValue / OnWriteValue
/ ResolveFullRef look the FullReference up via that map instead of
casting NodeId.Identifier. The old cast path is preserved as a
fallback so any test fixture that still registers variables with
FullRef-shaped NodeIds keeps working.
* EquipmentNodeWalker.AddTagVariable now extracts the cross-driver
`FullName` field from Tag.TagConfig before handing the address to
DriverAttributeInfo. Every shipped driver stores the wire reference in
TagConfig[FullName]; falling back to the raw string covers any future
driver that wants an opaque non-JSON address. ExtractFullName is
exposed internal for unit coverage.
* scripts/e2e/test-galaxy.ps1 defaults updated to the new path-based
NodeIds. Verified live against p7-smoke-galaxy on the dev box:
`ns=2;s=p7-smoke-galaxy/lab-floor/galaxy-line/reactor-1/Source` reads
return Status=0x00000000 with a real Galaxy byte-array value.
Test suite: 195/195 Core.Tests + 283/283 Server.Tests green. Five new
ExtractFullName / FullName-passthrough tests added.
Task #112 GA-3 — golden-path read verified end-to-end; remaining E2E
script stages still blocked on pre-existing issues (ScriptedAlarm
predicate NRE on empty upstream cache, PowerShell $changeLines.Count
guard), tracked separately.
Task #134 — complete.

Galaxy IPC unblock — live dev-box E2E path
Three root-cause fixes to get an elevated dev-box shell past session open through to real MXAccess reads: 1. PipeAcl — drop BUILTIN\Administrators deny ACE. UAC's filtered token carries the Admins SID as deny-only, so the deny fired even from non-elevated admin-account shells. The per-connection SID check in PipeServer.VerifyCaller remains the real authorization boundary. 2. PipeServer — swap the Hello-read / VerifyCaller order. ImpersonateNamedPipeClient returns ERROR_CANNOT_IMPERSONATE until at least one frame has been read from the pipe; reading Hello first satisfies that rule. Previously the ACL deny-first path masked this race — removing the deny ACE exposed it. 3. GalaxyIpcClient — add a background reader + single pending-response slot. A RuntimeStatusChange event between OpenSessionRequest and OpenSessionResponse used to satisfy the caller's single ReadFrameAsync and fail CallAsync with "Expected OpenSessionResponse, got RuntimeStatusChange". The reader now routes response kinds (and ErrorResponse) to the pending TCS and everything else to a handler the driver registers in InitializeAsync. The Proxy was already set up to raise managed events from RaiseDataChange / RaiseAlarmEvent / OnHostConnectivityUpdate — those helpers had no caller until now. 4. RedundancyPublisherHostedService — swallow BadServerHalted while polling host.Server.CurrentInstance. StandardServer throws that code during startup rather than returning null, so the first poll attempt crashed the BackgroundService (and the host) before OnServerStarted ran. This race was latent behind the Galaxy init failure above. Updates docs that described the Admins deny ACE + mandatory non-elevated shells, and drops the admin-skip guards from every Galaxy integration + E2E fixture that had them (IpcHandshakeIntegrationTests, EndToEndIpcTests, ParityFixture, LiveStackFixture, HostSubprocessParityTests). Adds GalaxyIpcClientRoutingTests covering the router's request/response match, ErrorResponse, event-between-call, idle event, and peer-close paths. Verified live on the dev box against the p7-smoke cluster (gen 6): driver registered=1 failedInit=0, Phase 7 bridge subscribed, OPC UA server up on 4840, MXAccess read round-trip returns real data with Status=0x00000000. Task #112 — partial: Galaxy live stack is functional end-to-end. The supplied test-galaxy.ps1 script still fails because the UNS walker encodes TagConfig JSON as the tag's NodeId instead of the seeded TagId (pre-existing; separate issue from this commit).

Phase 6.2 Stream C.12 — lock in ScopePathIndexBuilder semantics with tests
Closes task #123 (partial — builder semantics unit-tested; production wiring is the new task #133). ScopePathIndexBuilder + NodeScopeResolver indexed mode already exist — they produce a full Cluster → Namespace → UnsArea → UnsLine → Equipment → Tag scope from the published generation's config rows. What was missing: unit coverage of the Build semantics (the only consumers were compile-time references) + explicit acknowledgement in the readiness doc that the gate/resolver aren't yet wired into Program.cs. Tests — 6 cases in ScopePathIndexBuilderTests.cs: - Well-formed content emits full hierarchy. - Tags with null EquipmentId skipped (SystemPlatform-namespace fallback). - Tags with broken Equipment FK skipped (publish-time validation should have caught; builder is defensive). - Equipment with broken Line FK skipped. - Duplicate TagConfig throws InvalidOperationException. - Resolver with index returns full-path scope; un-indexed ref falls through to cluster-only scope (pre-ADR-001 behaviour preserved). Server.Tests 277 → 283. Critical follow-up (task #133): Program.cs still constructs OpcUaApplicationHost WITHOUT authzGate or scopeResolver, so all six dispatch-layer gates (Read, Write, HistoryRead, Browse, CreateMonitoredItems, Call) are currently inert in production. Wiring them up — load NodeAcl + EquipmentNamespaceContent at bootstrap, construct gate + resolver, pass into OpcUaApplicationHost, rebind on generation refresh — is the last Phase 6.2 GA blocker. Docs: v2-release-readiness.md Phase 6.2 Stream C hardening list marks the scope-resolution bullet struck-through with a close-out note that calls out the gate-inert-in-production gap + task #133.

Phase 6.2 Stream C — Call + Alarm Acknowledge/Confirm gating
Closes task #122 (Acknowledge + Confirm + generic Call — Shelve stays as a follow-up pending per-instance method-NodeId resolution). Before this commit any session with a connected channel could invoke method nodes on driver-materialized equipment — including alarm Acknowledge / Confirm. Combined with the Browse + CreateMonitoredItems gates that landed earlier in Stream C, this was the last service-layer entry point where a session could still affect state without passing the authz trie. Implementation on DriverNodeManager: - `Call` override — pre-iterates methodsToCall, gates each through AuthorizationGate with the operation kind returned by MapCallOperation. Denied calls get errors[i] = BadUserAccessDenied before delegating to base.Call. - `MapCallOperation(NodeId methodId)` — maps well-known Part 9 method NodeIds to dedicated operation kinds: MethodIds.AcknowledgeableConditionType_Acknowledge → OpcUaOperation.AlarmAcknowledge MethodIds.AcknowledgeableConditionType_Confirm → OpcUaOperation.AlarmConfirm everything else → OpcUaOperation.Call Lets the ACL distinguish "can acknowledge alarms" from "can invoke arbitrary methods" without conflating the two roles. - Shelve dispatch paths through per-instance ShelvedStateMachine methods with dynamic NodeIds that can't be constant-matched — falls through to generic Call. Fine-grained OpcUaOperation.AlarmShelve is a follow- up when the method-invocation path grows a "method-role" annotation. Extracted GateCallMethodRequests + MapCallOperation as static internal for unit-testability. 8 new tests (MapCallOperation Acknowledge / Confirm / generic; gate-null no-op, denied-Acknowledge, allowed- Acknowledge, mixed-batch, pre-populated-error-preserved). Server.Tests 269 → 277. Known follow-ups: - Shelve per-operation gating (see above). - TranslateBrowsePathsToNodeIds gating (Browse follow-up from #120).

Phase 6.2 Stream C — CreateMonitoredItems per-item gating
Closes task #121 (partial — creation-time gate; decision #153 per-item revocation stamp is a follow-up). Before this commit a session could subscribe to any node via CreateMonitoredItems, even nodes where Read was denied — the subscription would surface BadUserAccessDenied on each data-change read, but the client saw a successful CreateMonitoredItems response and held the subscription open, wasting resources and leaking the address-space shape through the item metadata. New override on DriverNodeManager.CreateMonitoredItems: - Pre-iterates itemsToCreate, gates each through AuthorizationGate with OpcUaOperation.CreateMonitoredItems at the target node's scope. - For denied slots: sets errors[i] = new ServiceResult( StatusCodes.BadUserAccessDenied). The OPC Foundation base stack honours pre-populated non-success errors and skips item creation for those slots — the subscription never holds a handle to a denied node. - Preserves prior errors (e.g. BadNodeIdUnknown) — first diagnosis wins. - Non-string-identifier references (stack-synthesized numeric ids) bypass the gate. Extracted the pure filter logic into GateMonitoredItemCreateRequests(items, errors, identity, gate, scopeResolver) — static internal, unit-testable without the OPC UA server stack. Tests — 6 new in MonitoredItemGatingTests.cs (gate-null no-op, denied-gets-BadUserAccessDenied, allowed-passes, mixed-batch-denies- per-item, pre-populated-error-preserved, numeric-id-bypass). Server.Tests 263 → 269. Known follow-ups: - Per-item (AuthGenerationId, MembershipVersion) stamp (decision #153) for detecting revocation mid-subscription — needs subscription-layer plumbing. - TransferSubscriptions not yet wired (same pattern, smaller scope).

Phase 6.2 Stream C — Browse gating on DriverNodeManager
Closes task #120 (partial — strict point-check; ancestor-visibility implication is a follow-up). Before this commit DriverNodeManager exposed every materialized node to every browsing session regardless of the user's ACL. Read + Write + HistoryRead were already gated through AuthorizationGate in Phase 6.2 Stream C core; Browse was the one surface where the session could still enumerate nodes it had no permission to touch, discovering structure even when reads failed with BadUserAccessDenied. Implementation - New `Browse` override on DriverNodeManager that calls base.Browse first (lets the stack populate the reference list normally), then post-filters the IList<ReferenceDescription> so denied nodes are removed silently. OPC UA convention: Browse filtering is invisible to the client; no BadUserAccessDenied surfaces. - Extracted the filter loop into the static internal `FilterBrowseReferences(references, userIdentity, gate, scopeResolver)` so the policy is unit-testable without standing up the full OPC UA server stack. - Non-string NodeId identifiers (stack-synthesized standard-type references with numeric identifiers) bypass the gate — only driver- materialized nodes key into the authz trie. - When AuthorizationGate or NodeScopeResolver is null, the filter is a no-op — preserves the pre-Phase-6.2 dispatch path for integration tests that construct DriverNodeManager without authz. Tests — 6 new in BrowseGatingTests.cs (gate-null no-op, empty-list no-op, denied-removed, allowed-passes-through, numeric-id bypass, lax-mode null-identity keeps references). Server.Tests 257 → 263. Known follow-up (tracked implicitly under #120 re-scope): - Ancestor-visibility implication (acl-design.md §Browse line 111): a user with Read at `Line/Tag` should be able to Browse `Line` even without an explicit Browse grant. Current filter does a strict point-check. Proper fix needs TriePermissionEvaluator to expose a "subtree-has-any-grant" query. - TranslateBrowsePathsToNodeIds not yet filtered (same extension pattern; small follow-up). Docs: v2-release-readiness.md Phase 6.2 Stream C hardening list marks the Browse bullet struck-through with "Partial" close-out note.

Phase 6.3 A.2 + D.1 — GenerationRefreshHostedService: poll + lease-wrap apply
Closes tasks #132 + #118 (GA hardening backlog). Before this commit, the Server only observed the generation in force at process start (SealedBootstrap). Peer-published generations accumulated in the shared config DB while the running node kept serving the generation it had sealed on boot. Two consequences: 1. Operator role-swaps required a process restart — Admin publishes a new generation, but the Server's RedundancyCoordinator never re-read the topology. 2. ApplyLeaseRegistry had no apply to wrap. ServiceLevelBand sat at PrimaryHealthy (255) during every publish because nothing opened a lease; PrimaryMidApply (200) was effectively dead code. New GenerationRefreshHostedService (src/.../Server/Hosting/): - Polls sp_GetCurrentGenerationForCluster every 5s (tunable). - On change: opens leases.BeginApplyLease(newGenerationId, Guid.NewGuid()), calls coordinator.RefreshAsync inside the `await using`, releases on scope exit (success / exception / cancellation via IAsyncDisposable). - Diagnostic properties: LastAppliedGenerationId, TickCount, RefreshCount. - Delegate-injected currentGenerationQuery for test drive-through; real path is the private static DefaultQueryCurrentGenerationAsync. - Registered as HostedService in Program.cs alongside the Phase 6.3 redundancy / peer-probe stack. Scope intentionally narrow: only the coordinator refreshes today. Driver re-init, virtual-tag re-bind, script-engine reload remain as follow-up wiring. The lease wrap is the right seam for those subscribers to hook once they grow hot-reload support — the doc comments say so. Tests - 5 new unit tests in GenerationRefreshHostedServiceTests (first-apply, identity no-op, change-triggers-refresh, null-generation-is-no-op, lease-is-released-on-exit). Stub generation-query delegate; real coordinator backed by EF InMemory DB. - Server.Tests total 252 → 257. Docs - v2-release-readiness.md Phase 6.3 follow-ups list marks the sp_PublishGeneration lease wrap bullet struck-through with close-out note.

Phase 6.3 Stream B — peer-probe HostedServices populating PeerReachabilityTracker
Closes task #116 (GA hardening backlog). Before this commit the RedundancyStatePublisher saw PeerReachability.Unknown for every peer because the tracker had no writers — every healthy peer got degraded to the Isolated-Primary band (230) even when fully reachable. Not release-blocking (safe default), but not the full non-transparent- redundancy UX either. Two-layer probe model per docs/v2/implementation/phase-6-3-redundancy-runtime.md §Stream B: - PeerHttpProbeLoop (Stream B.1) — fast-fail layer at 2 s / 1 s timeout. Hits each peer's http://{Host}:{DashboardPort}/healthz via an injected IHttpClientFactory. Writes the HTTP bit of PeerReachability while preserving the UA bit from the last UA probe so a transient HTTP blip doesn't clobber the authoritative UA reading. - PeerUaProbeLoop (Stream B.2) — authoritative layer at 10 s / 5 s timeout. Calls DiscoveryClient.GetEndpoints against opc.tcp://{Host}: {OpcUaPort} — cheap compared to a full Session.Create, no cert trust required. Short-circuits when the HTTP probe last reported the peer unhealthy (no wasted handshakes on a known-dead endpoint), clearing the stale UaHealthy bit in that case. Both inherit from BackgroundService, follow the tick/delay/catch pattern RedundancyPublisherHostedService + ResilienceStatusPublisherHostedService established, and expose TickAsync() as internal for test drive-through. New PeerProbeOptions class carries the four intervals/timeouts so operators can tune cadence per site. Registered as singleton in Program.cs; HTTP client registered by name so the OtOpcUa handler chain (Serilog enrichers, potential future OpenTelemetry instrumentation) isn't bypassed. Tests — 9 new unit tests across PeerHttpProbeLoopTests (5) and PeerUaProbeLoopTests (4). All pass. Server.Tests total 243 → 252. Full solution build clean. Docs: v2-release-readiness.md Phase 6.3 follow-ups list marks the peer-probe bullet struck-through with a close-out note. Still deferred in Phase 6.3: - OPC UA variable-node binding (task #117 — ServiceLevel + ServerUriArray) - sp_PublishGeneration lease wrap (task #118) - Client interop matrix (task #119) Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Unblock phase-6 compliance meta-runner on task-galaxy-e2e
Two small fixes so `scripts/compliance/phase-6-all.ps1` exits 0 — this is GA exit-criterion #1 from docs/v2/v2-release-readiness.md. 1. Admin csproj: bump OpenTelemetry.Extensions.Hosting 1.15.2 → 1.15.3 + OpenTelemetry.Exporter.Prometheus.AspNetCore 1.15.2-beta.1 → 1.15.3-beta.1. Fixes NU1902 moderate-severity advisory (GHSA-g94r-2vxg-569j) on the transitive OpenTelemetry.Api 1.15.2 pull. TreatWarningsAsErrors on the Admin project promoted the advisory to an error and failed the whole `dotnet test` run at restore. 2. SchemaComplianceTests.All_expected_tables_exist: the expected-tables list drifted behind four Phase 7 migration additions — Script, ScriptedAlarm, ScriptedAlarmState, VirtualTag. The EF model + live migrations have carried these tables for a while; the compliance test just needed the four names added. Applied migrations against a scratch DB to confirm the list is exhaustive. Verification: full solution test pass 2301 / 2301 (one tolerated pre-existing CLI flake). Phase 6 aggregate compliance: all four phases PASS with no test-count regression.

FOCAS — retire Tier-C split, inline managed wire client, make read-only
Migration closes the FOCAS Tier-C architecture. OtOpcUa previously had
`Driver.FOCAS.Host` (NSSM-wrapped Windows service loading Fwlib64.dll via
P/Invoke) + `Driver.FOCAS.Shared` (MessagePack IPC contracts) + a C shim
DLL stand-in for unit tests. All of it is deleted; the driver is now a
single in-process managed assembly talking the FOCAS/2 Ethernet binary
protocol directly on TCP:8193.
Architecture
- Pure-managed `FocasWireClient` inlined at `src/.../Driver.FOCAS/Wire/`
(owner-imported — see Wire/FocasWireClient.cs for the full surface).
Opens two TCP sockets, runs the initiate handshake, serialises requests
on socket 2 through a semaphore, closes cleanly with PDU + socket
teardown. Both sync `IDisposable` and async `IAsyncDisposable`.
- `WireFocasClient` (same folder) adapts the wire client to OtOpcUa's
`IFocasClient` surface — fixed-tree reads, PARAM/MACRO/PMC addresses,
alarms. Writes return `BadNotWritable` by design — OtOpcUa is read-only
against FOCAS.
- `FocasDriverFactoryExtensions` now accepts `"Backend": "wire"` (default)
and `"Backend": "unimplemented"`. Legacy `ipc` and `fwlib` backends are
rejected at startup with a diagnostic pointing at the migration doc.
Deletions
- `src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Host/` — whole project + Ipc/,
Backend/, Stability/, Program.cs.
- `src/ZB.MOM.WW.OtOpcUa.Driver.FOCAS.Shared/` — Contracts/, FrameReader,
FrameWriter, whole project.
- `tests/...Driver.FOCAS.Host.Tests/` + `.Shared.Tests/` — whole projects.
- `src/.../Driver.FOCAS/FwlibNative.cs` + `FwlibFocasClient.cs` — 21
P/Invokes + 7 `Pack=1` marshalling structs + the Fwlib-backed
`IFocasClient` implementation.
- `src/.../Driver.FOCAS/Ipc/` + `Supervisor/` — IPC client wrapper +
Host-process supervisor (backoff, circuit breaker, heartbeat, post-
mortem reader, process launcher).
- `scripts/install/Install-FocasHost.ps1` — NSSM service installer.
- `tests/.../Driver.FOCAS.Tests/{IpcFocasClientTests, IpcLoopback,
FwlibNativeHelperTests, PostMortemReaderCompatibilityTests,
SupervisorTests, FocasDriverFactoryExtensionsTests}.cs` — tests that
exercised the retired surfaces.
- `tests/.../Driver.FOCAS.IntegrationTests/Shim/` — the zig-built C shim
DLL that masqueraded as Fwlib64.dll.
Solution changes
- `ZB.MOM.WW.OtOpcUa.slnx` drops the 4 retired project refs.
- `src/.../Driver.FOCAS.csproj` drops the Shared ProjectReference, adds
`Microsoft.Extensions.Logging.Abstractions` for the optional `ILogger`
hook in `FocasWireClient`.
- `src/.../Driver.FOCAS.Cli.csproj` drops the six `<Content Include>`
entries that copied `vendor/fanuc/*.dll` into the CLI bin. CLI now uses
`WireFocasClient` directly.
- `FocasDriver` default factory flips to `Wire.WireFocasClientFactory`.
Integration tests
- New `tests/.../Driver.FOCAS.IntegrationTests/` project covering fixed-
tree reads (identity, axes, dynamic, program, operation mode, timers,
spindle load + max RPM, servo meters), user-authored PARAM / MACRO /
PMC reads, `DiscoverAsync` emission, `SubscribeAsync` + `OnDataChange`,
`IAlarmSource` raise/clear transitions, and `ProbeAsync` /
`OnHostStatusChanged`. 9 e2e tests against the focas-mock fixture
(Docker container with the vendored Python mock's native FOCAS/2
Ethernet responder).
- `scripts/integration/run-focas.ps1` orchestrates compose up → tests →
compose down. Dropped the shim-build stage + DLL-copy step + the split
testhost workaround (the latter only existed because of native-DLL
lifecycle bugs the shim tripped).
- Docker compose collapses from 11 per-series services to one `focas-sim`
service. Tests seed per-series state via `mock_load_profile` at test
start.
- Vendored focas-mock snapshot refreshed to pick up upstream's native
FOCAS/2 Ethernet responder (was 660 lines, now 1018) — the
pre-refresh snapshot only spoke the JSON admin protocol.
Tests
- 145/145 unit tests in `Driver.FOCAS.Tests` pass (was 208 pre-deletion;
63 removed tests exercised the retired IPC/shim/supervisor/Fwlib
surfaces).
- 9/9 integration tests pass against the refreshed mock.
- `FocasScaffoldingTests.Unimplemented_factory_throws_on_Create…` updated
to assert the new diagnostic message pointing at
`docs/drivers/FOCAS.md` rather than the now-gone `Fwlib64.dll`.
Docs
- `docs/drivers/FOCAS.md` rewritten for the managed wire topology —
deployment collapses to one `"Backend": "wire"` config block, no
separate service, no DLL deployment, no pipe ACL.
- `docs/drivers/FOCAS-Test-Fixture.md` updated — single TCP probe skip
gate instead of TCP + shim probe; fewer moving parts.
- `docs/drivers/README.md` row for FOCAS reflects the Tier-A managed
topology (previously listed Tier-C + `Fwlib64.dll` P/Invoke).
- `docs/Driver.FOCAS.Cli.md` drops the Tier-C architecture-note section.
- `docs/v2/implementation/focas-isolation-plan.md` marked historical —
the plan it documents was executed then superseded by the wire client.
- `docs/v2/v2-release-readiness.md` re-audited 2026-04-24. Phase 5
driver complement closed. FOCAS change-log entry added.

FOCAS — commit previously-orphaned support files
Brings seven FOCAS-related files into git that shipped as part of earlier FOCAS work but were never staged. Adding them now so the tree reflects the compilable state + pre-empts dead references from the migration commit that follows: - src/.../Driver.FOCAS/FocasAlarmProjection.cs — raise/clear diffing + severity mapping surfaced via IAlarmSource on FocasDriver. Referenced by committed FocasDriver.cs; tests in FocasAlarmProjectionTests.cs. - src/.../Admin/Services/FocasDriverDetailService.cs — Admin UI per-instance detail page data source. - src/.../Admin/Components/Pages/Drivers/FocasDetail.razor — Blazor page rendering the above (from task #69). - tests/.../Admin.Tests/FocasDriverDetailServiceTests.cs — exercises the detail service. - tests/.../Driver.FOCAS.Tests/FocasAlarmProjectionTests.cs — raise/clear diff semantics against FakeFocasClient. - tests/.../Driver.FOCAS.Tests/FocasHandleRecycleTests.cs — proactive recycle cadence test. - docs/v2/implementation/focas-wire-protocol.md — captured FOCAS/2 Ethernet wire protocol reference. Useful going forward even though the Tier-C / simulator plan docs are historical. No runtime behaviour change — these files compile today and the solution build/test pass already depends on them.

Task #222 partial — unblock AB Legacy PCCC via cip-path workaround (5/5 stages)
Replaced the "ab_server PCCC upstream-broken" skip gate with the actual
root cause: libplctag's ab_server rejects empty CIP routing paths at the
unconnected-send layer before the PCCC dispatcher runs. Real SLC/
MicroLogix/PLC-5 hardware accepts empty paths (no backplane); ab_server
does not. With `/1,0` in place, N (Int16), F (Float32), and L (Int32)
file reads + writes round-trip cleanly across all three compose profiles.
## Fixture changes
- `AbLegacyServerFixture.cs`:
- Drop `AB_LEGACY_TRUST_WIRE` env var + the reachable-but-untrusted
skip branch. Fixture now only skips on TCP unreachability.
- Add `AB_LEGACY_CIP_PATH` env var (default `1,0`) + expose `CipPath`
property. Set `AB_LEGACY_CIP_PATH=` (empty) against real hardware.
- Shorter skip messages on the `[AbLegacyFact]` / `[AbLegacyTheory]`
attributes — one reason: endpoint not reachable.
- `AbLegacyReadSmokeTests.cs`:
- Device URI built from `sim.CipPath` instead of hardcoded empty path.
- New `AB_LEGACY_COMPOSE_PROFILE` env var filters the parametric
theory to the running container's family. Only one container binds
`:44818` at a time, so cross-family params would otherwise fail.
- `Slc500_write_then_read_round_trip` skips cleanly when the running
profile isn't `slc500`.
## E2E + seed + docs
- `scripts/e2e/test-ablegacy.ps1` — drop the `AB_LEGACY_TRUST_WIRE`
skip gate; synopsis calls out the `/1,0` vs empty cip-path split
between the Docker fixture and real hardware.
- `scripts/e2e/e2e-config.sample.json` — sample gateway flipped from
the hardware placeholder (`192.168.1.10`) to the Docker fixture
(`127.0.0.1/1,0`); comment rewritten.
- `scripts/e2e/README.md` — AB Legacy expected-matrix row goes from
SKIP to PASS.
- `scripts/smoke/seed-ablegacy-smoke.sql` — default HostAddress points
at the Docker fixture + header / footer text reflect the new state.
- `tests/.../Docker/README.md` — "Known limitations" section rewritten
to describe the cip-path gate (not a dispatcher gap); env-var table
picks up `AB_LEGACY_CIP_PATH` + `AB_LEGACY_COMPOSE_PROFILE`.
- `docs/drivers/AbLegacy-Test-Fixture.md` + `docs/drivers/README.md`
+ `docs/DriverClis.md` — flip status from blocked to functional;
residual bit-file-write gap (B3:0/5 → 0x803D0000) documented.
## Residual gap
Bit-file writes (`B3:0/5` style) surface `0x803D0000` against
`ab_server --plc=SLC500`; bit reads work. Non-blocking for smoke
coverage — N/F/L round-trip is enough. Real hardware / RSEmulate 500
for bit-write fidelity. Documented in `Docker/README.md` §"Known
limitations" + the `AbLegacy-Test-Fixture.md` follow-ups list.
## Verified
- Full-solution build: 0 errors, 334 pre-existing warnings.
- Integration suite passes per-profile with
`AB_LEGACY_COMPOSE_PROFILE=<slc500|micrologix|plc5>` + matching
compose container up.
- All four non-hardware e2e scripts (Modbus / AB CIP / AB Legacy / S7)
now 5/5 against the respective docker-compose fixtures.

Task #251 — S7 + TwinCAT test-client CLIs (driver CLI suite complete)
Final two of the five driver test clients. Pattern carried forward from #249 (Modbus) + #250 (AB CIP, AB Legacy) — each CLI inherits Driver.Cli.Common for DriverCommandBase + SnapshotFormatter and adds a protocol-specific CommandBase + 4 commands (probe / read / write / subscribe). New projects: - src/ZB.MOM.WW.OtOpcUa.Driver.S7.Cli/ — otopcua-s7-cli. S7CommandBase carries host/port/cpu/rack/slot/timeout. Handles all S7 atomic types (Bool, Byte, Int16..UInt64, Float32/64, String, DateTime). DateTime parses via RoundtripKind so "2026-04-21T12:34:56Z" works. - src/ZB.MOM.WW.OtOpcUa.Driver.TwinCAT.Cli/ — otopcua-twincat-cli. TwinCATCommandBase carries ams-net-id + ams-port + --poll-only toggle (flips UseNativeNotifications=false). Covers the full IEC 61131-3 atomic set: Bool, SInt/USInt, Int/UInt, DInt/UDInt, LInt/ULInt, Real, LReal, String, WString, Time/Date/DateTime/TimeOfDay. Structure writes refused as out-of-scope (same as AB CIP). IEC time/date variants marshal as UDINT on the wire per IEC spec. Subscribe banner announces "ADS notification" vs "polling" so the mechanism is obvious in bug reports. Tests (49 new, 122 cumulative driver-CLI): - S7: 22 tests. Every S7DataType has a happy-path + bounds case. DateTime round-trips an ISO-8601 string. Tag-name synthesis round-trips every S7 address form (DB / M / I / Q, bit/word/dword, strings). - TwinCAT: 27 tests. Full IEC type matrix including WString UTF-8 pass- through + the four IEC time/date variants landing on UDINT. Structure rejection case. Tag-name synthesis for Program scope, GVL scope, nested UDT members, and array elements.

Task #250 — AB CIP + AB Legacy test-client CLIs
Second + third of the four driver test clients. Both follow the same shape as otopcua-modbus-cli (#249) and consume Driver.Cli.Common for DriverCommandBase + SnapshotFormatter. New projects: - src/ZB.MOM.WW.OtOpcUa.Driver.AbCip.Cli/ — otopcua-abcip-cli. AbCipCommandBase carries gateway (ab://host[:port]/cip-path) + family (ControlLogix/CompactLogix/Micro800/GuardLogix) + timeout. Commands: probe, read, write, subscribe. Value parser covers every AbCipDataType atomic type (Bool, SInt..LInt, USInt..ULInt, Real, LReal, String, Dt); Structure writes refused as out-of-scope for the CLI. - src/ZB.MOM.WW.OtOpcUa.Driver.AbLegacy.Cli/ — otopcua-ablegacy-cli. AbLegacyCommandBase carries gateway + plc-type (Slc500/MicroLogix/Plc5/ LogixPccc) + timeout. Commands: probe (default address N7:0), read, write, subscribe. Value parser covers Bit, Int, Long, Float, AnalogInt, String, and the three sub-element types (TimerElement / CounterElement / ControlElement all land on int32 at the wire). Tests (35 new, 73 cumulative across the driver CLI family): - AB CIP: 17 tests — ParseValue happy-paths for every Logix atomic type, failure cases (non-numeric / bool garbage), tag-name synthesis. - AB Legacy: 18 tests — ParseValue coverage (Bit / Int / AnalogInt / Long / Float / String / sub-elements), PCCC address round-trip in tag names including bit-within-word + sub-element syntax. Docs: - docs/Driver.AbCip.Cli.md — family ↔ CIP-path cheat sheet + examples per command + typical workflows. - docs/Driver.AbLegacy.Cli.md — PCCC address primer (file letters → CLI --type) + known ab_server upstream gap cross-ref to #224 close-out. Wiring: - ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests). Full-solution build clean. `otopcua-abcip-cli --help` + `otopcua-ablegacy-cli --help` verified end-to-end. Next up (#251): S7 + TwinCAT CLIs, same pattern. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Task #249 — Driver test-client CLIs: shared lib + Modbus CLI first
Mirrors the v1 otopcua-cli value prop (ad-hoc shell-level PLC validation) for
the Modbus-TCP driver, and lays down the shared scaffolding that AB CIP, AB
Legacy, S7, and TwinCAT CLIs will build on.
New projects:
- src/ZB.MOM.WW.OtOpcUa.Driver.Cli.Common/ — DriverCommandBase (verbose
flag + Serilog config) + SnapshotFormatter (single-tag + table +
write-result renders with invariant-culture value formatting + OPC UA
status-code shortnames + UTC-normalised timestamps).
- src/ZB.MOM.WW.OtOpcUa.Driver.Modbus.Cli/ — otopcua-modbus-cli executable.
Commands: probe, read, write, subscribe. ModbusCommandBase carries the
host/port/unit-id flags + builds ModbusDriverOptions with Probe.Enabled
=false (CLI runs are one-shot; driver-internal keep-alive would race).
Commands + coverage:
- probe single FC03 + GetHealth() + pretty-print
- read region × address × type synth into one driver tag
- write same shape + --value parsed per --type
- subscribe polled-subscription stream until Ctrl+C
Tests (38 total):
- 16 SnapshotFormatterTests covering: status-code shortnames, unknown
codes fall back to hex, null value + timestamp placeholders, bool
lowercase, float invariant culture, string quoting, write-result shape,
aligned table columns, mismatched-length rejection, UTC normalisation.
- 22 Modbus CLI tests:
· ReadCommandTests.SynthesiseTagName (5 theory cases)
· WriteCommandParseValueTests (17 cases: bool aliases, unknown rejected,
Int16 bounds, UInt16/Bcd16 type, Float32/64 invariant culture,
String passthrough, BitInRegister, Int32 MinValue, non-numeric reject)
Wiring:
- ZB.MOM.WW.OtOpcUa.slnx grew 4 entries (2 src + 2 tests).
- docs/Driver.Modbus.Cli.md — operator-facing runbook with examples per
command + output format + typical workflows.
Regression: full-solution build clean; shared-lib tests 16/0, Modbus CLI tests
22/0.
Next up: repeat the pattern for AB CIP (shares ~40% more with Modbus via
libplctag), then AB Legacy, S7, TwinCAT. The shared base stays as-is unless
one of those exposes a gap the Modbus-first pass missed.

Task #224 close — AB Legacy PCCC fixture: add AB_LEGACY_TRUST_WIRE opt-in for wire-level runs
The ab_server Docker simulator accepts TCP at :44818 when started with
--plc=SLC500 but its PCCC dispatcher is a confirmed upstream gap
(verified 2026-04-21 with --debug=5: zero request logs when libplctag
issues a read, every read surfaces BadCommunicationError 0x80050000).
Previous behavior — when Docker was up, the three smoke tests ran and
all failed on every integration-host run. Noise, not signal.
New behavior — AbLegacyServerFixture gates on a new env var
AB_LEGACY_TRUST_WIRE:
Endpoint reachable? | TRUST_WIRE set? | Result
--------------------+-----------------+------------------------------
No | — | Skip ("not reachable")
Yes | No | Skip ("ab_server PCCC gap")
Yes | 1 / true | Run
The fixture's new skip reason explicitly names the upstream gap + the
resolution paths (upstream bug / RSEmulate golden-box / real hardware
via task #222 lab rig). Operators with a real SLC 5/05 / MicroLogix
1100/1400 / PLC-5 or an Emulate box set AB_LEGACY_ENDPOINT + TRUST_WIRE
and the smoke tests round-trip cleanly.
Updated docs:
- tests/.../Docker/README.md — new env-var table + three-case gate matrix
- Known limitations section refreshed to "confirmed upstream gap"
Verified locally:
- Docker down: 2 skipped.
- Docker up + TRUST_WIRE unset: 2 skipped (upstream-gap message).
- Docker up + TRUST_WIRE=1: 4 run, 4 fail BadCommunicationError (ab_server gap as expected).
- Unit suite: 96 passed / 0 failed (regression-clean).

Task #242 finish — UnsTab drag-drop interactive Playwright E2E tests un-skip + pass
Closes the scope-out left by the #242 partial. Root cause of the blazor.web.js zero-byte response turned out to be two co-operating harness bugs: 1) The static-asset manifest was discoverable but the runtime needs UseStaticWebAssets to be called so the StaticWebAssetsLoader composes a PhysicalFileProvider per ContentRoot declared in staticwebassets.development.json (Admin source wwwroot + obj/compressed + the framework NuGet cache). Without that call MapStaticAssets resolves the route but has no ContentRoot map — so every asset serves zero bytes. 2) The EF InMemory DB name was being re-generated on every DbContext construction (the lambda body called Guid.NewGuid() inline), so the seed scope, Blazor circuit scope, and test-assertion scopes all got separate stores. Capturing the name as a stable string per fixture instance fixes the "cluster not found → page stays at Loading…" symptom. Fixes: - AdminWebAppFactory: * ApplicationName set on WebApplicationOptions so UseStaticWebAssets discovers the manifest. * builder.WebHost.UseStaticWebAssets() wired explicitly (matches what `dotnet run` does via MSBuild targets). * dbName captured once per fixture; the options lambda reads the captured string instead of re-rolling a Guid. - UnsTabDragDropE2ETests: the two [Fact(Skip=...)] tests un-skip. Suite state: 3 passed, 0 skipped, 0 failed. Task #242 closed. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Task #242 partial — UnsTab interactive E2E test bodies + harness upgrades (tests Skip-guarded pending blazor.web.js asset plumbing)
Carries the interactive drag-drop + 409 concurrent-edit test bodies (full Playwright
flows against the real @ondragstart/@ondragover/@ondrop handlers + modal + EF state
round-trip), plus several harness upgrades that push the in-process
WebApplication-based fixture closer to a working Blazor Server circuit. The
interactive tests are marked [Fact(Skip=...)] pending resolution of one remaining
blocker documented in the class docstring.
Harness upgrades (AdminWebAppFactory):
- Environment set to Development so 500s surface exception stacks (rather than
the generic error page) during future diagnosis.
- ContentRootPath pointed at the Admin assembly dir so wwwroot + manifest files
resolve.
- Wired SignalR hubs (/hubs/fleet, /hubs/alerts) so ClusterDetail's HubConnection
negotiation no longer 500s at first render.
- Services property exposed so tests can open scoped DI contexts against the
running host (scheduled peer-edit simulation, post-commit state assertion).
Remaining blocker (reason for Skip):
/_framework/blazor.web.js returns HTTP 200 with a zero-byte body. The asset's
route is declared in OtOpcUa.Admin.staticwebassets.endpoints.json, but the
underlying file is shipped by the framework NuGet package
(Microsoft.AspNetCore.App.Internal.Assets/_framework/blazor.web.js) rather than
copied into the Admin wwwroot. MapStaticAssets can't resolve it without wiring
a composite FileProvider or the WebRootPath machinery. Three viable next-session
approaches listed in the class docstring:
(a) Composite FileProvider mapping /_framework/* → NuGet cache.
(b) Subprocess harness spawning real dotnet run of Admin project with an
InMemory-DB override (closest to production composition).
(c) MSBuild ItemGroup in the test csproj that copies framework files into the
test output + ContentRoot=test assembly dir with UseStaticFiles.
Scaffolding smoke test (Admin_host_serves_HTTP_via_Playwright_scaffolding) stays
green unchanged.
Suite state: 1 passed, 2 skipped, 0 failed.

Task #220 — Wire FOCAS into DriverFactoryRegistry bootstrap pipeline
Closes the non-hardware gap surfaced in the #220 audit: FOCAS had full Tier-C architecture (Driver.FOCAS + Driver.FOCAS.Host + Driver.FOCAS.Shared, supervisor, post-mortem MMF, NSSM scripts, 239 tests) but no factory registration, so config-DB DriverInstance rows of type "FOCAS" would fail at bootstrap with "unknown driver type". Hardware-gated FwlibHostedBackend (real Fwlib32 P/Invoke inside the Host process) stays deferred under #222 lab-rig. Ships: - FocasDriverFactoryExtensions.Register(registry) mirroring the Galaxy pattern. JSON schema selects backend via "Backend" field: "ipc" (default) — IpcFocasClientFactory → named-pipe FocasIpcClient → Driver.FOCAS.Host process (Tier-C isolation) "fwlib" — direct in-process FwlibFocasClientFactory (P/Invoke) "unimplemented" — UnimplementedFocasClientFactory (fail-fast on use — useful for staging DriverInstance rows pre-Host-deploy) - Devices / Tags / Probe / Timeout / Series feed into FocasDriverOptions. Series validated eagerly at top-level so typos fail at bootstrap, not first read. Tag DataType + Series enum values surface clear errors listing valid options. - Program.cs adds FocasDriverFactoryExtensions.Register alongside Galaxy. - Driver.FOCAS.csproj references Core (for DriverFactoryRegistry). - Server.csproj adds Driver.FOCAS ProjectReference so the factory type is reachable from Program.cs. Tests: 13 new FocasDriverFactoryExtensionsTests covering: registry entry, case-insensitive lookup, ipc backend with full config, ipc defaults, missing PipeName/SharedSecret errors, fwlib backend short-path, unimplemented backend, unknown-backend error, unknown-Series error, tag missing DataType, null/ws args, duplicate-register throws. Regression: 202 FOCAS + 13 FOCAS.Host + 24 FOCAS.Shared + 239 Server all pass. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Task #219 follow-up — close AlarmConditionState child-NodeId + event-propagation gaps
PR #197 surfaced two integration-level wiring gaps in DriverNodeManager's MarkAsAlarmCondition path; this commit fixes both and upgrades the integration test to assert them end-to-end. Fix 1 — addressable child nodes: AlarmConditionState inherits ~50 typed children (Severity / Message / ActiveState / AckedState / EnabledState / …). The stack was leaving them with Foundation-namespace NodeIds (type-declaration defaults) or shared ns=0 counter allocations, so client Read on a child returned BadNodeIdUnknown. Pass assignNodeIds=true to alarm.Create, then walk the condition subtree and rewrite each descendant's NodeId symbolically as {condition-full-ref}.{symbolic-path} in the node manager's namespace. Stable, unique, and collision-free across multiple alarm instances in the same driver. Fix 2 — event propagation to Server.EventNotifier: OPC UA Part 9 event propagation relies on the alarm condition being reachable from Objects/Server via HasNotifier. Call CustomNodeManager2.AddRootNotifier(alarm) after registering the condition so subscriptions placed on Server-object EventNotifier receive the ReportEvent calls ConditionSink emits per-transition. Test upgrades in AlarmSubscribeIntegrationTests: - Driver_alarm_transition_updates_server_side_AlarmConditionState_node — now asserts Severity == 700, Message text, and ActiveState.Id == true through the OPC UA client (previously scoped out as BadNodeIdUnknown). - New: Driver_alarm_event_flows_to_client_subscription_on_Server_EventNotifier subscribes an OPC UA event monitor on ObjectIds.Server, fires a driver transition, and waits for the AlarmConditionType event to be delivered, asserting Message + Severity fields. Previously scoped out as "Part 9 event propagation out of reach." Regression checks: 239 server tests pass (+1 new event-subscription test), 195 Core tests pass.

Task #219 — Server-integration test coverage for IAlarmSource dispatch path
Adds AlarmSubscribeIntegrationTests alongside HistoryReadIntegrationTests so both
optional driver capabilities — IHistoryProvider (already covered) and IAlarmSource
(new) — have end-to-end coverage that boots the full OPC UA stack and exercises the
wiring path from driver event → GenericDriverNodeManager forwarder → DriverNodeManager
ConditionSink through a real Session.
Two tests:
1. Driver_alarm_transition_updates_server_side_AlarmConditionState_node — a fake
IAlarmSource declares an IsAlarm=true variable, calls MarkAsAlarmCondition in
DiscoverAsync, and fires OnAlarmEvent for that source. Verifies the
client can browse the alarm condition node at FullReference + ".Condition"
and reads the DisplayName back through Session.Read.
2. Each_IsAlarm_variable_registers_its_own_condition_node_in_the_driver_namespace —
two IsAlarm variables each produce their own addressable AlarmConditionState,
proving the CapturingHandle per-variable registration works.
Scoped-out (documented in the class docstring): the stack exposes AlarmConditionState's
inherited children (Severity / Message / ActiveState / …) with Foundation-namespace
NodeIds that DriverNodeManager does not add to its predefined-node index, so reading
those child attributes through a client returns BadNodeIdUnknown. OPC UA Part 9 event
propagation (subscribe-on-Server + ConditionRefresh) is likewise out of reach until
the node manager wires HasNotifier + child-node registration. The existing Core-level
GenericDriverNodeManagerTests cover the in-memory alarm-sink fan-out semantics.
Full Server.Tests suite: 238 passed, 0 failed.

Driver-instance bootstrap pipeline (#248) — DriverInstance rows materialise as live IDriver instances
Closes the gap surfaced by Phase 7 live smoke (#240): DriverInstance rows in the central config DB had no path to materialise as live IDriver instances in DriverHost, so virtual-tag scripts read BadNodeIdUnknown for every tag. ## DriverFactoryRegistry (Core.Hosting) Process-singleton type-name → factory map. Each driver project's static Register call pre-loads its factory at Program.cs startup; the bootstrapper looks up by DriverInstance.DriverType + invokes with (DriverInstanceId, DriverConfig JSON). Case-insensitive; duplicate-type registration throws. ## GalaxyProxyDriverFactoryExtensions.Register (Driver.Galaxy.Proxy) Static helper — no Microsoft.Extensions.DependencyInjection dep, keeps the driver project free of DI machinery. Parses DriverConfig JSON for PipeName + SharedSecret + ConnectTimeoutMs. DriverInstanceId from the row wins over JSON per the schema's UX_DriverInstance_Generation_LogicalId. ## DriverInstanceBootstrapper (Server) After NodeBootstrap loads the published generation: queries DriverInstance rows scoped to that generation, looks up the factory per row, constructs + DriverHost.RegisterAsync (which calls InitializeAsync). Per plan decision #12 (driver isolation), failure of one driver doesn't prevent others — logs ERR + continues + returns the count actually registered. Unknown DriverType (factory not registered) logs WRN + skips so a missing-assembly deployment doesn't take down the whole server. ## Wired into OpcUaServerService.ExecuteAsync After NodeBootstrap.LoadCurrentGenerationAsync, before PopulateEquipmentContentAsync + Phase7Composer.PrepareAsync. The Phase 7 chain now sees a populated DriverHost so CachedTagUpstreamSource has an upstream feed. ## Live evidence on the dev box Re-ran the Phase 7 smoke from task #240. Pre-#248 vs post-#248: Equipment namespace snapshots loaded for 0/0 driver(s) ← before Equipment namespace snapshots loaded for 1/1 driver(s) ← after Galaxy.Host pipe ACL denied our SID (env-config issue documented in docs/ServiceHosting.md, NOT a code issue) — the bootstrapper logged it as "failed to initialize, driver state will reflect Faulted" and continued past the failure exactly per plan #12. The rest of the pipeline (Equipment walker + Phase 7 composer) ran to completion. ## Tests — 5 new DriverFactoryRegistryTests Register + TryGet round-trip, case-insensitive lookup, duplicate-type throws, null-arg guards, RegisteredTypes snapshot. Pure functions; no DI/DB needed. The bootstrapper's DB-query path is exercised by the live smoke (#240) which operators run before each release. |

Phase 7 follow-up #247 — Galaxy.Host historian writer + SQLite sink activation
Closes the historian leg of Phase 7. Scripted alarm transitions now batch-flow through the existing Galaxy.Host pipe + queue durably in a local SQLite store- and-forward when Galaxy is the registered driver, instead of being dropped into NullAlarmHistorianSink. ## GalaxyHistorianWriter (Driver.Galaxy.Proxy.Ipc) IAlarmHistorianWriter implementation. Translates AlarmHistorianEvent → HistorianAlarmEventDto (Stream D contract), batches via the existing GalaxyIpcClient.CallAsync round-trip on MessageKind.HistorianAlarmEventRequest / Response, maps per-event HistorianAlarmEventOutcomeDto bytes back to HistorianWriteOutcome (Ack/RetryPlease/PermanentFail) so the SQLite drain worker knows what to ack vs dead-letter vs retry. Empty-batch fast path. Pipe-level transport faults (broken pipe, host crash) bubble up as GalaxyIpcException which the SQLite sink's drain worker translates to whole-batch RetryPlease per its catch contract. ## GalaxyProxyDriver implements IAlarmHistorianWriter Marker interface lets Phase7Composer discover it via type check at compose time. WriteBatchAsync delegates to a thin GalaxyHistorianWriter wrapping the driver's existing _client. Throws InvalidOperationException if InitializeAsync hasn't connected yet — the SQLite drain worker treats that as a transient batch failure and retries. ## Phase7Composer.ResolveHistorianSink Replaces the injected sink dep when any registered driver implements IAlarmHistorianWriter. Constructs SqliteStoreAndForwardSink at %ProgramData%/OtOpcUa/alarm-historian-queue.db (falls back to %TEMP% when ProgramData unavailable, e.g. dev), starts the 2s drain timer, owns the sink disposable for clean teardown. When no driver provides the writer, keeps the NullAlarmHistorianSink wired by Program.cs (#246). DisposeAsync now also disposes the owned SQLite sink in the right order: bridge → engines → owned sink → injected fallback. ## Tests — 7 new GalaxyHistorianWriterMappingTests ToDto round-trips every field; preserves null Comment; per-byte outcome enum mapping (Ack / RetryPlease / PermanentFail) via [Theory]; unknown byte throws; ctor null-guard. The IPC round-trip itself is covered by the live Host suite (task #240) which constructs a real pipe. Server.Phase7 tests: 34/34 still pass; Galaxy.Proxy tests: 25/25 (+7 = 32 total). ## Phase 7 production wiring chain — COMPLETE - ✅ #243 composition kernel - ✅ #245 scripted-alarm IReadable adapter - ✅ #244 driver bridge - ✅ #246 Program.cs wire-in - ✅ #247 this — Galaxy.Host historian writer + SQLite sink activation What unblocks now: task #240 live OPC UA E2E smoke. With a Galaxy driver registered, scripted alarm transitions flow end-to-end through the engine → SQLite queue → drain worker → Galaxy.Host IPC → Aveva Historian alarm schema. Without Galaxy, NullSink keeps the engines functional and the queue dormant. |

Phase 7 follow-up #246 — Phase7Composer + Program.cs wire-in
Activates the Phase 7 engines in production. Loads Script + VirtualTag + ScriptedAlarm rows from the bootstrapped generation, wires the engines through the Phase7EngineComposer kernel (#243), starts the DriverSubscriptionBridge feed (#244), and late-binds the resulting IReadable sources to OpcUaApplicationHost before OPC UA server start. ## Phase7Composer (Server.Phase7) Singleton orchestrator. PrepareAsync loads the three Phase 7 row sets in one DB scope, builds CachedTagUpstreamSource, calls Phase7EngineComposer.Compose, constructs DriverSubscriptionBridge with one DriverFeed per registered ISubscribable driver (path-to-fullRef map built from EquipmentNamespaceContent via MapPathsToFullRefs), starts the bridge. DisposeAsync tears down in the right order: bridge first (no more events fired into the cache), then engines (cascades + timers stop), then any disposable sink. MapPathsToFullRefs: deterministic path convention is /{areaName}/{lineName}/{equipmentName}/{tagName} matching exactly what EquipmentNodeWalker emits into the OPC UA browse tree, so script literals against the operator-visible UNS tree work without translation. Tags missing EquipmentId or pointing at unknown Equipment are skipped silently (Galaxy SystemPlatform-style tags + dangling references handled). ## OpcUaApplicationHost.SetPhase7Sources New late-bind setter. Throws InvalidOperationException if called after StartAsync because OtOpcUaServer + DriverNodeManagers capture the field values at construction; mutation post-start would silently fail. ## OpcUaServerService After bootstrap loads the current generation, calls phase7Composer.PrepareAsync + applicationHost.SetPhase7Sources before applicationHost.StartAsync. StopAsync disposes Phase7Composer first so the bridge stops feeding the cache before the OPC UA server tears down its node managers (avoids in-flight cascades surfacing as noisy shutdown warnings). ## Program.cs Registers IAlarmHistorianSink as NullAlarmHistorianSink.Instance (task #247 swaps in the real Galaxy.Host-writer-backed SqliteStoreAndForwardSink), Serilog root logger, and Phase7Composer singleton. ## Tests — 5 new Phase7ComposerMappingTests = 34 Phase 7 tests total Maps tag → walker UNS path, skips null EquipmentId, skips unknown Equipment reference, multiple tags under same equipment map distinctly, empty content yields empty map. Pure functions; no DI/DB needed. The real PrepareAsync DB query path can't be exercised without SQL Server in the test environment — it's exercised by the live E2E smoke (task #240) which unblocks once #247 lands. ## Phase 7 production wiring chain status - ✅ #243 composition kernel - ✅ #245 scripted-alarm IReadable adapter - ✅ #244 driver bridge - ✅ #246 this — Program.cs wire-in - 🟡 #247 — Galaxy.Host SqliteStoreAndForwardSink writer adapter (replaces NullSink) - 🟡 #240 — live E2E smoke (unblocks once #247 lands) |

Phase 7 follow-up #244 — DriverSubscriptionBridge
Pumps live driver OnDataChange notifications into CachedTagUpstreamSource so ctx.GetTag in user scripts sees the freshest driver value. The last missing piece between #243 (composition kernel) and #246 (Program.cs wire-in). ## DriverSubscriptionBridge IAsyncDisposable. Per DriverFeed: groups all paths for one ISubscribable into a single SubscribeAsync call (consolidating polled drivers' work + giving native-subscription drivers one watch list), keeps a per-feed reverse map from driver-opaque fullRef back to script-side UNS path, hooks OnDataChange to translate + push into the cache. DisposeAsync awaits UnsubscribeAsync per active subscription + unhooks every handler so events post-dispose are silent. Empty PathToFullRef map → feed skipped (no SubscribeAsync call). Subscribe failure on any feed unhooks that feed's handler + propagates so misconfiguration aborts bridge start cleanly. Double-Start throws InvalidOperationException; double-Dispose is idempotent. OTOPCUA0001 suppressed at the two ISubscribable call sites with comments explaining the carve-out: bridge is the lifecycle-coordinator for Phase 7 subscriptions (one Subscribe at engine compose, one Unsubscribe at shutdown), not the per-call hot-path. Driver Read dispatch still goes through CapabilityInvoker via DriverNodeManager. ## Tests — 9 new = 29 Phase 7 tests total DriverSubscriptionBridgeTests covers: SubscribeAsync called with distinct fullRefs, OnDataChange pushes to cache keyed by UNS path, unmapped fullRef ignored, empty PathToFullRef skips Subscribe, DisposeAsync unsubscribes + unhooks (post-dispose events don't push), StartAsync called twice throws, DisposeAsync idempotent, Subscribe failure unhooks handler + propagates, ctor null guards. ## Phase 7 production wiring chain status - #243 ✅ composition kernel - #245 ✅ scripted-alarm IReadable adapter - #244 ✅ this — driver bridge - #246 pending — Program.cs Compose call + SqliteStoreAndForwardSink lifecycle - #240 pending — live E2E smoke (unblocks once #246 lands) |

Phase 7 follow-up #245 — ScriptedAlarmReadable adapter over engine state
Task #245 — exposes each scripted alarm's current ActiveState as IReadable so OPC UA variable reads on Source=ScriptedAlarm nodes return the live predicate truth instead of BadNotFound. ## ScriptedAlarmReadable Wraps ScriptedAlarmEngine + implements IReadable: - Known alarm + Active → DataValueSnapshot(true, Good) - Known alarm + Inactive → DataValueSnapshot(false, Good) - Unknown alarm id → DataValueSnapshot(null, BadNodeIdUnknown) — surfaces misconfiguration rather than silently reading false - Batch reads preserve request order Phase7EngineComposer.Compose now returns this as ScriptedAlarmReadable when ScriptedAlarm rows are present. ScriptedAlarmSource (IAlarmSource for the event stream) stays in place — the IReadable is a separate adapter over the same engine. ## Tests — 6 new + 1 updated composer test = 19 total Phase 7 tests ScriptedAlarmReadableTests covers: inactive + active predicate → bool snapshot, unknown alarm id → BadNodeIdUnknown, batch order preservation, null-engine + null-fullReferences guards. The active-predicate test uses ctx.GetTag on a seeded upstream value to drive a real cascade through the engine. Updated Phase7EngineComposerTests to assert ScriptedAlarmReadable is non-null when alarms compose, null when only virtual tags. ## Follow-ups remaining - #244 — driver-bridge feed populating CachedTagUpstreamSource - #246 — Program.cs Compose call + SqliteStoreAndForwardSink lifecycle |

Phase 7 follow-up #243 — CachedTagUpstreamSource + Phase7EngineComposer
Ships the composition kernel that maps Config DB rows (Script / VirtualTag /
ScriptedAlarm) to the runtime definitions VirtualTagEngine + ScriptedAlarmEngine
consume, builds the engine instances, and wires OnEvent → historian-sink routing.
## src/ZB.MOM.WW.OtOpcUa.Server/Phase7/
- CachedTagUpstreamSource — implements both Core.VirtualTags.ITagUpstreamSource and
Core.ScriptedAlarms.ITagUpstreamSource (identical shape, distinct namespaces) on one
concrete type so the composer can hand one instance to both engines. Thread-safe
ConcurrentDictionary value cache with synchronous ReadTag + fire-on-write
Push(path, snapshot) that fans out to every observer registered via SubscribeTag.
Unknown-path reads return a BadNodeIdUnknown-quality snapshot (status 0x80340000)
so scripts branch on quality naturally.
- Phase7EngineComposer.Compose(scripts, virtualTags, scriptedAlarms, upstream,
alarmStateStore, historianSink, rootScriptLogger, loggerFactory) — single static
entry point that:
* Indexes scripts by ScriptId, resolves VirtualTag.ScriptId + ScriptedAlarm.PredicateScriptId
to full SourceCode
* Projects DB rows to VirtualTagDefinition + ScriptedAlarmDefinition (mapping
DataType string → DriverDataType enum, AlarmType string → AlarmKind enum,
Severity 1..1000 → AlarmSeverity bucket matching the OPC UA Part 9 bands
that AbCipAlarmProjection + OpcUaClient MapSeverity already use)
* Constructs VirtualTagEngine + loads definitions (throws InvalidOperationException
with the list of scripts that failed to compile — aggregated like Streams B+C)
* Constructs ScriptedAlarmEngine + loads definitions + wires OnEvent →
IAlarmHistorianSink.EnqueueAsync using ScriptedAlarmEvent.Emission as the event
kind + Condition.LastAckUser/LastAckComment for audit fields
* Returns Phase7ComposedSources with Disposables list the caller owns
Empty Phase 7 config returns Phase7ComposedSources.Empty so deployments without
scripts / alarms behave exactly as pre-Phase-7. Non-null sources flow into
OpcUaApplicationHost's virtualReadable / scriptedAlarmReadable plumbing landed by
task #239 — DriverNodeManager then dispatches reads by NodeSourceKind per PR #186.
## Tests — 12/12
CachedTagUpstreamSourceTests (6):
- Unknown-path read returns BadNodeIdUnknown-quality snapshot
- Push-then-Read returns cached value
- Push fans out to subscribers in registration order
- Push to one path doesn't fire another path's observer
- Dispose of subscription handle stops fan-out
- Satisfies both Core.VirtualTags + Core.ScriptedAlarms ITagUpstreamSource interfaces
Phase7EngineComposerTests (6):
- Empty rows → Phase7ComposedSources.Empty (both sources null)
- VirtualTag rows → VirtualReadable non-null + Disposables populated
- Missing script reference throws InvalidOperationException with the missing ScriptId
in the message
- Disabled VirtualTag row skipped by projection
- TimerIntervalMs → TimeSpan.FromMilliseconds round-trip
- Severity 1..1000 maps to Low/Medium/High/Critical at 250/500/750 boundaries
(matches AbCipAlarmProjection + OpcUaClient.MapSeverity banding)
## Scope — what this PR does NOT do
The composition kernel is the tricky part; the remaining wiring is three narrower
follow-ups that each build on this PR:
- task #244 — driver-bridge feed that populates CachedTagUpstreamSource from live
driver subscriptions. Without this, ctx.GetTag returns BadNodeIdUnknown even when
the driver has a fresh value.
- task #245 — ScriptedAlarmReadable adapter exposing each alarm's current Active
state as IReadable. Phase7EngineComposer.Compose currently returns
ScriptedAlarmReadable=null so reads on Source=ScriptedAlarm variables return
BadNotFound per the ADR-002 "misconfiguration not silent fallback" signal.
- task #246 — Program.cs call to Phase7EngineComposer.Compose with config rows
loaded from the sealed-cache DB read, plus SqliteStoreAndForwardSink lifecycle
wiring at %ProgramData%/OtOpcUa/alarm-historian-queue.db with the Galaxy.Host
IPC writer from Stream D.
Task #240 (live OPC UA E2E smoke) depends on all three follow-ups landing.

Admin.E2ETests scaffolding — Playwright + Kestrel + InMemory DB + test auth
Ships the E2E infrastructure filed against task #199 (UnsTab drag-drop Playwright smoke). The Blazor Server interactive-render assertion through a test-owned pipeline needs a dedicated diagnosis pass — filed as task #242 — but the Playwright harness lands here so that follow-up starts from a known-good scaffolding rather than setting up the project from scratch. ## New project tests/ZB.MOM.WW.OtOpcUa.Admin.E2ETests - AdminWebAppFactory — boots the Admin pipeline with Kestrel on a free loopback port, swaps the SQL DbContext for EF Core InMemory, replaces the LDAP cookie auth with TestAuthHandler, mirrors the Razor-components/auth/antiforgery pipeline, and seeds a cluster + draft generation with areas warsaw / berlin and a line-a1 in warsaw. Not a WebApplicationFactory<Program> because WAF's TestServer transport doesn't coexist cleanly with Kestrel-on-a-real-port, which Playwright needs. - TestAuthHandler — stamps every request with a FleetAdmin claim so tests hit authenticated routes without the LDAP bind. - PlaywrightFixture — one Chromium launch shared across tests; throws PlaywrightBrowserMissingException when the binary isn't installed so tests can Assert.Skip rather than fail hard. - UnsTabDragDropE2ETests.Admin_host_serves_HTTP_via_Playwright_scaffolding — proves the full stack comes up: Kestrel bind, InMemory DbContext, test auth, Playwright navigation, Razor route pipeline responds with HTML < 500. One passing test. ## Prerequisite Chromium must be installed locally: pwsh tests/ZB.MOM.WW.OtOpcUa.Admin.E2ETests/bin/Debug/net10.0/playwright.ps1 install chromium Absent the browser, the suite Assert.Skip's cleanly — CI without the install step still reports green. Once installed, `dotnet test` runs the scaffolding smoke in ~12s. ## Follow-up (task #242) Diagnose why `/clusters/{id}/draft/{gen}` → UNS-tab click → drag-drop flow times out under the test-owned Program.cs replica. Candidate causes: route-ordering difference, missing SignalR hub mapping timing, JS interop asset differences, culture middleware. Once the interactive circuit boots, add: - happy-path drag-drop assertion (source row → target area → Confirm → assert re-parent) - 409 conflict variant (preview → external DB mutation → Confirm → assert red-header modal) |

Phase 7 Stream G follow-up — DriverNodeManager dispatch routing by NodeSourceKind
Honors the ADR-002 discriminator at OPC UA Read/Write dispatch time. Virtual tag reads route to the VirtualTagEngine-backed IReadable; scripted alarm reads route to the ScriptedAlarmEngine-backed IReadable; driver reads continue to route to the driver's own IReadable (no regression for any existing driver test). ## Changes DriverNodeManager ctor gains optional `virtualReadable` + `scriptedAlarmReadable` parameters. When callers omit them (every existing driver test) the manager behaves exactly as before. SealedBootstrap wires the engines' IReadable adapters once the Phase 7 composition root is added. Per-variable NodeSourceKind tracked in `_sourceByFullRef` during Variable() registration alongside the existing `_writeIdempotentByFullRef` / `_securityByFullRef` maps. OnReadValue now picks the IReadable by source kind via the new internal SelectReadable helper. When the engine-backed IReadable isn't wired (virtual tag node but no engine provided), returns BadNotFound rather than silently falling back to the driver — surfaces a misconfiguration instead of masking it. OnWriteValue gates on IsWriteAllowedBySource which returns true only for Driver. Plan decision #6: virtual tags + scripted alarms reject direct OPC UA writes with BadUserAccessDenied. Scripts write virtual tags via `ctx.SetVirtualTag`; operators ack alarms via the Part 9 method nodes. ## Tests — 7/7 (internal helpers exposed via InternalsVisibleTo) DriverNodeManagerSourceDispatchTests covers: - Driver source routes to driver IReadable - Virtual source routes to virtual IReadable - ScriptedAlarm source routes to alarm IReadable - Virtual source with null virtual IReadable returns null (→ BadNotFound) - ScriptedAlarm source with null alarm IReadable returns null - Driver source with null driver IReadable returns null (preserves BadNotReadable) - IsWriteAllowedBySource: only Driver=true (Virtual=false, ScriptedAlarm=false) Full solution builds clean. Phase 7 test total now 197 green. |

Phase 7 Stream F — Admin UI for scripts + test harness + historian diagnostics
Adds the draft-editor tab + page surface for authoring Phase 7 virtual tags and scripted alarms, plus the /alarms/historian operator diagnostics page. Monaco loads from CDN via a progressive-enhancement JS shim — the textarea works immediately so the page is functional even if the CDN is unreachable. ## New services (Admin) - ScriptService — CRUD for Script entity. SHA-256 SourceHash recomputed on save so Core.Scripting's CompiledScriptCache hits on re-publish of unchanged source + misses when the source actually changes. - VirtualTagService — CRUD for VirtualTag, with Enabled toggle. - ScriptedAlarmService — CRUD for ScriptedAlarm + lookup of persistent ScriptedAlarmState (logical-id-keyed per plan decision #14). - ScriptTestHarnessService — pre-publish dry-run. Enforces plan decision #22: only inputs the DependencyExtractor identifies can be supplied. Missing / extra synthetic inputs surface as dedicated outcomes. Captures SetVirtualTag writes + Serilog events from the script so the operator can see both the output + the log output before publishing. - HistorianDiagnosticsService — surfaces the local-process IAlarmHistorianSink state on /alarms/historian. Null sink reports Disabled + swallows retry. Live SqliteStoreAndForwardSink reports real queue depth + last-error + drain state and routes the Retry-dead-lettered button through. ## New UI - ScriptsTab.razor (inside DraftEditor tabs) — list + create/edit/delete scripts with Monaco editor + dependency preview + test-harness run panel showing output + writes + log emissions. - ScriptEditor.razor — reusable Monaco-backed textarea. Loads editor from CDN via wwwroot/js/monaco-loader.js. Textarea stays authoritative for Blazor binding; Monaco mirrors into it on every keystroke. - AlarmsHistorian.razor (/alarms/historian) — queue depth + dead-letter depth + drain state badge + last-error banner + Retry-dead-lettered button. - DraftEditor.razor — new "Scripts" tab. ## DI wiring All five services registered in Program.cs. Null historian sink bound at Admin composition time (real SqliteStoreAndForwardSink lives in the Server process). ## Tests — 13/13 Phase7ServicesTests covers: - ScriptService: Add generates logical id + hash, Update recomputes hash on source change, Update same-source keeps hash (cache-hit preservation), Delete is idempotent - VirtualTagService: round-trips trigger flags, Enabled toggle works - ScriptedAlarmService: HistorizeToAveva defaults true per plan decision #15 - ScriptTestHarness: successful run captures output + writes, rejects missing / extra inputs, rejects non-literal paths, compile errors surface as Threw - HistorianDiagnosticsService: null sink reports Disabled + retry returns 0 |

Phase 7 Stream G — Address-space integration (NodeSourceKind + walker emits VirtualTag/ScriptedAlarm)
Per ADR-002, adds the Driver/Virtual/ScriptedAlarm discriminator to DriverAttributeInfo
so the DriverNodeManager's dispatch layer can route Read/Write/Subscribe to the right
runtime subsystem — drivers (unchanged), VirtualTagEngine (Phase 7 Stream B), or
ScriptedAlarmEngine (Phase 7 Stream C).
## Changes
- NodeSourceKind enum added to Core.Abstractions (Driver=0/Virtual=1/ScriptedAlarm=2).
- DriverAttributeInfo gains Source / VirtualTagId / ScriptedAlarmId parameters — all
default so existing call sites (every driver) compile unchanged.
- EquipmentNamespaceContent gains VirtualTags + ScriptedAlarms optional collections.
- EquipmentNodeWalker emits:
- Virtual-tag variables — Source=Virtual, VirtualTagId set, Historize flag honored
- Scripted-alarm variables — Source=ScriptedAlarm, ScriptedAlarmId set, IsAlarm=true
(triggers node-manager AlarmConditionState materialization)
- Skips disabled virtual tags + scripted alarms
## Tests — 13/13 in EquipmentNodeWalkerTests (5 new)
- Virtual-tag variables carry Source=Virtual + VirtualTagId + Historize flag
- Scripted-alarm variables carry Source=ScriptedAlarm + IsAlarm=true + Boolean type
- Disabled rows skipped
- Null VirtualTags/ScriptedAlarms collections safe (back-compat for non-Phase-7 callers)
- Driver tags default Source=Driver (ensures no discriminator regression)
## Next
Stream G follow-up: DriverNodeManager dispatch (Read/Write/Subscribe routing by
NodeSourceKind), SealedBootstrap wiring of VirtualTagEngine + ScriptedAlarmEngine,
end-to-end integration test.

Phase 7 Stream E — Config DB schema for scripts, virtual tags, scripted alarms, and alarm state
Adds the four tables Streams B/C/F consume — Script (generation-scoped source code), VirtualTag (generation-scoped calculated-tag config), ScriptedAlarm (generation-scoped alarm config), and ScriptedAlarmState (logical-id-keyed persistent runtime state). ## New entities (net10, EF Core) - Script — stable logical ScriptId carries across generations; SourceHash is the compile-cache key (matches Core.Scripting's CompiledScriptCache). - VirtualTag — mandatory EquipmentId FK (plan decision #2, unified Equipment tree); ChangeTriggered/TimerIntervalMs + Historize flags; check constraints enforce "at least one trigger" + "timer >= 50ms". - ScriptedAlarm — required AlarmType ('AlarmCondition'/'LimitAlarm'/'OffNormalAlarm'/ 'DiscreteAlarm'); Severity 1..1000 range check; HistorizeToAveva default true per plan decision #15. - ScriptedAlarmState — keyed ONLY on ScriptedAlarmId (NOT generation-scoped) per plan decision #14 — ack state + audit trail must follow alarm identity across Modified generations. CommentsJson has ISJSON check for GxP audit. ## Migration EF-generated 20260420231641_AddPhase7ScriptingTables covers all 4 tables + indexes + check constraints + FKs to ConfigGeneration. sp_PublishGeneration required no changes — it only flips Draft->Published status; the new entities already carry GenerationId so they publish atomically with the rest of the config. ## Tests — 12/12 (design-time model introspection) Phase7ScriptingEntitiesTests covers: table registration, column maxlength + column types, unique indexes (Generation+LogicalId, Generation+EquipmentPath for VirtualTag and ScriptedAlarm), secondary indexes (SourceHash for cache lookup), check constraints (trigger-required, timer-min, severity-range, alarm-type-enum, CommentsJson-IsJson), ScriptedAlarmState PK is alarm-id not generation-scoped, ScriptedAlarm defaults (HistorizeToAveva=true, Retain=true, Severity=500, Enabled=true), DbSets wired, and the generated migration type exists for rollforward. |

Phase 7 Stream D — Historian alarm sink (SQLite store-and-forward + Galaxy.Host IPC contracts)
Phase 7 plan decisions #16, #17, #19, #21 implementation. Durable local SQLite queue absorbs every qualifying alarm event; drain worker forwards batches to Galaxy.Host (reusing the already-loaded 32-bit aahClientManaged DLLs) on an exponential-backoff cadence; operator acks never block on the historian being reachable. ## New project Core.AlarmHistorian (net10) - AlarmHistorianEvent — source-agnostic event shape (scripted alarms + Galaxy-native + AB CIP ALMD + any future IAlarmSource) - IAlarmHistorianSink / NullAlarmHistorianSink — interface + disabled default - IAlarmHistorianWriter — per-event outcome (Ack / RetryPlease / PermanentFail); Stream G wires the Galaxy.Host IPC client implementation - SqliteStoreAndForwardSink — full implementation: - Queue table with AttemptCount / LastError / DeadLettered columns - DrainOnceAsync serialised via SemaphoreSlim - BackoffLadder 1s → 2s → 5s → 15s → 60s (cap) - DefaultCapacity 1,000,000 rows — overflow evicts oldest non-dead-lettered - DefaultDeadLetterRetention 30 days — sweeper purges on every drain tick - RetryDeadLettered operator action reattaches dead-letters to the regular queue - Writer-side exceptions treated as whole-batch RetryPlease (no data loss) ## New IPC contracts in Driver.Galaxy.Shared - HistorianAlarmEventRequest — batched up to 100 events/request per plan Stream D.5 - HistorianAlarmEventResponse — per-event outcome (1:1 with request order) - HistorianAlarmEventOutcomeDto enum (byte on the wire — Ack/RetryPlease/PermanentFail) - HistorianAlarmEventDto — mirrors Core.AlarmHistorian.AlarmHistorianEvent - HistorianConnectivityStatusNotification — Host pushes proactively when the SDK session drops so /alarms/historian flips red without waiting for the next drain - MessageKind additions: 0x80 HistorianAlarmEventRequest / 0x81 HistorianAlarmEventResponse / 0x82 HistorianConnectivityStatus ## Tests — 14/14 SqliteStoreAndForwardSinkTests covers: enqueue→drain→Ack round-trip, empty-queue no-op, RetryPlease bumps backoff + keeps row, Ack after Retry resets backoff, PermanentFail dead-letters one row without blocking neighbors, writer exception treated as whole-batch retry with error surfaced in status, capacity eviction drops oldest non-dead-lettered, dead-letters purged past retention window, RetryDeadLettered requeues, ladder caps at 60s after 10 retries, Null sink reports Disabled status, null sink swallows enqueue, ctor argument validation, disposed sink rejects enqueue. ## Totals Full Phase 7 tests: 160 green (63 Scripting + 36 VirtualTags + 47 ScriptedAlarms + 14 AlarmHistorian). Stream G wires this into the real Galaxy.Host IPC pipe. |

Phase 7 Stream C — Core.ScriptedAlarms project (Part 9 state machine + predicate engine + IAlarmSource adapter)
Ships the Part 9 alarm fidelity layer Phase 7 committed to in plan decision #5. Every scripted alarm gets a full OPC UA AlarmConditionType state machine — EnabledState, ActiveState, AckedState, ConfirmedState, ShelvingState — with persistent operator-supplied state across server restarts per Phase 7 plan decision #14. Runtime shape matches the Galaxy-native + AB CIP ALMD alarm sources: scripted alarms fan out through the existing IAlarmSource surface so Phase 6.1 AlarmTracker composition consumes them without per-source branching. Part9StateMachine is a pure-functions module — no instance state, no I/O, no mutation. Every transition (ApplyPredicate, ApplyAcknowledge, ApplyConfirm, ApplyOneShotShelve, ApplyTimedShelve, ApplyUnshelve, ApplyEnable, ApplyDisable, ApplyAddComment, ApplyShelvingCheck) takes the current AlarmConditionState record plus the event and returns a fresh state + EmissionKind hint. Two structural invariants enforced: disabled alarms never transition ActiveState / AckedState / ConfirmedState; shelved alarms still advance state (so startup recovery reflects reality) but emit a Suppressed hint so subscribers do not see the transition. OneShot shelving expires on clear; Timed shelving expires via ApplyShelvingCheck against the UnshelveAtUtc timestamp. Comments are append-only — every acknowledge, confirm, shelve, unshelve, enable, disable, explicit add-comment, and auto-unshelve appends an AlarmComment record with user identity + timestamp + kind + text for the GxP / 21 CFR Part 11 audit surface. AlarmConditionState is the persistent record the store saves. Fields: AlarmId, Enabled, Active, Acked, Confirmed, Shelving (kind + UnshelveAtUtc), LastTransitionUtc, LastActiveUtc, LastClearedUtc, LastAckUtc + LastAckUser + LastAckComment, LastConfirmUtc + LastConfirmUser + LastConfirmComment, Comments. Fresh factory initializes everything to the no-event position. IAlarmStateStore is the persistence abstraction — LoadAsync, LoadAllAsync, SaveAsync, RemoveAsync. Stream E wires this to a SQL-backed store with IAuditLogger hooks; tests use InMemoryAlarmStateStore. Startup recovery per Phase 7 plan decision #14: LoadAsync runs every configured alarm predicate against current tag values to rederive ActiveState, but EnabledState / AckedState / ConfirmedState / ShelvingState + audit history are loaded verbatim from the store so operators do not re-ack after an outage and shelved alarms stay shelved through maintenance windows. MessageTemplate implements Phase 7 plan decision #13 — static-with-substitution. {TagPath} tokens resolved at event emission time from the engine value cache. Missing paths, non-Good quality, or null values all resolve to {?} so the event still fires but the operator sees where the reference broke. ExtractTokenPaths enumerates tokens at publish time so the engine knows to subscribe to every template-referenced tag in addition to predicate-referenced tags. AlarmPredicateContext is the ScriptContext subclass alarm scripts see. GetTag reads from the engine shared cache; SetVirtualTag is explicitly rejected at runtime with a pointed error message — alarm predicates must be pure so their output does not couple to virtual-tag state in ways that become impossible to reason about. If cross-tag side effects are needed, the operator authors a virtual tag and the alarm predicate reads it. ScriptedAlarmEngine orchestrates. LoadAsync compiles every predicate through Stream A ScriptSandbox + ForbiddenTypeAnalyzer, runs DependencyExtractor to find the read set, adds template token paths to the input set, reports every compile failure as one aggregated InvalidOperationException (not one-at-a-time), subscribes to each unique referenced upstream path, seeds the value cache, loads persisted state for each alarm (falling back to Fresh for first-load), re-evaluates the predicate, and saves the recovered state. ChangeTrigger — when an upstream tag changes, look up every alarm referencing that path in a per-path inverse index, enqueue all of them for re-evaluation via a SemaphoreSlim-gated path. Unlike the virtual-tag engine, scripted alarms are leaves in the evaluation DAG (no alarm drives another alarm), so no topological sort is needed. Operator actions (AcknowledgeAsync, ConfirmAsync, OneShotShelveAsync, TimedShelveAsync, UnshelveAsync, EnableAsync, DisableAsync, AddCommentAsync) route through the state machine, persist, and emit if there is an emission. A 5-second shelving-check timer auto-expires Timed shelving and emits Unshelved events at the right moment. Predicate evaluation errors (script throws, timeout, compile-time reads bad tag) leave the state unchanged — the engine does NOT invent a clear transition on predicate failure. Logged as scripts-*.log Error; companion WARN in main log. ScriptedAlarmSource implements IAlarmSource. SubscribeAlarmsAsync filter is a set of equipment-path prefixes; empty means all. AcknowledgeAsync from the base interface routes to the engine with user identity "opcua-client" — Stream G will replace this with the authenticated principal from the OPC UA dispatch layer. The adapter implements only the base IAlarmSource methods; richer Part 9 methods (Confirm, Shelve, Unshelve, AddComment) remain on the engine and will bind to OPC UA method nodes in Stream G. 47 unit tests across 5 files. Part9StateMachineTests (16) — every transition + noop edge cases: predicate true/false, same-state noop, disabled ignores predicate, acknowledge records user/comment/adds audit, idempotent acknowledge, reject no-user ack, full activate-ack-clear-confirm walk, one-shot shelve suppresses next activation, one-shot expires on clear, timed shelve requires future unshelve time, timed shelve expires via shelving-check, explicit unshelve emits, add-comment appends to audit, comments append-only through multiple operations, full lifecycle walk emits every expected EmissionKind. MessageTemplateTests (11) — no-token passthrough, single+multiple token substitution, bad quality becomes {?}, unknown path becomes {?}, null value becomes {?}, tokens with slashes+dots, empty + null template, ExtractTokenPaths returns every distinct path, whitespace inside tokens trimmed. ScriptedAlarmEngineTests (13) — load compiles+subscribes, compile failures aggregated, upstream change emits Activated, clearing emits Cleared, message template resolves at emission, ack persists to store, startup recovery preserves ack but rederives active, shelved activation state-advances but suppresses emission, runtime exception isolates to owning alarm, disable prevents activation until re-enable, AddComment appends audit without state change, SetVirtualTag from predicate rejected (state unchanged), Dispose releases upstream subscriptions. ScriptedAlarmSourceTests (5) — empty filter matches all, equipment-prefix filter, Unsubscribe stops events, AcknowledgeAsync routes with default user, null arguments rejected. FakeUpstream fixture gives tests an in-memory driver mock with subscription count tracking. Full Phase 7 test count after Stream C: 146 green (63 Scripting + 36 VirtualTags + 47 ScriptedAlarms). Stream D (historian alarm sink with SQLite store-and-forward + Galaxy.Host IPC) consumes ScriptedAlarmEvent + similar Galaxy / AB CIP emissions to produce the unified alarm timeline. Stream G wires the OPC UA method calls and AlarmSource into DriverNodeManager dispatch. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Phase 7 Stream B — Core.VirtualTags project (engine + dep graph + timer + source)
Ships the evaluation engine that consumes compiled scripts from Stream A, subscribes to upstream driver tags, runs on change + on timer, cascades evaluations through dependent virtual tags in topological order, and emits changes through a driver-capability-shaped adapter the DriverNodeManager can dispatch to per ADR-002. DependencyGraph owns the directed dep-graph where nodes are tag paths (driver tags implicit leaves, virtual tags registered internal nodes) and edges run from a virtual tag to each tag it reads. Kahn algorithm produces the topological sort. Tarjan iterative SCC detects every cycle in one pass so publish-time rejection surfaces all offending cycles together. Both iterative so 10k-deep chains do not StackOverflow. Re-adding a node overwrites prior dependency set cleanly (supports config-publish reloads). VirtualTagDefinition is the operator-authored config row (Path, DataType, ScriptSource, ChangeTriggered, TimerInterval, Historize). Stream E config DB materializes these on publish. ITagUpstreamSource is the abstraction the engine pulls driver tag values from. Stream G bridges this to IReadable + ISubscribable on live drivers; tests use FakeUpstream that tracks subscription count for leak-test assertions. IHistoryWriter is the per-tag Historize sink. NullHistoryWriter default when caller does not pass one. VirtualTagContext is the per-evaluation ScriptContext. Reads from engine last-known-value cache, writes route through SetVirtualTag callback so cross-tag side effects participate in change cascades. Injectable Now clock for deterministic tests. VirtualTagEngine orchestrates. Load compiles every script via ScriptSandbox, builds the dep graph via DependencyExtractor, checks for cycles, reports every compile failure in one error, subscribes to each referenced upstream path, seeds the value cache. EvaluateAllAsync runs topological order. EvaluateOneAsync is timer path. Read returns cached value. Subscribe registers observer. OnUpstreamChange updates cache, fans out, schedules transitive dependents (change-driven=false tags skipped). EvaluateInternalAsync holds a SemaphoreSlim so cascades do not interleave. Script exceptions and timeouts map per-tag to BadInternalError. Coercion from script double to config Int32 uses Convert.ToInt32. TimerTriggerScheduler groups tags by interval into shared Timers. Tags without TimerInterval not scheduled. VirtualTagSource implements IReadable + ISubscribable per ADR-002. ReadAsync returns cache. SubscribeAsync fires initial-data callback per OPC UA convention. IWritable deliberately not implemented — OPC UA writes to virtual tags rejected in DriverNodeManager per Phase 7 decision 6. 36 unit tests across 4 files: DependencyGraphTests 12, VirtualTagEngineTests 13, VirtualTagSourceTests 6, TimerTriggerSchedulerTests 4. Coverage includes cycle detection (self-loop, 2-node, 3-node, multiple disjoint), 2-level change cascade, per-tag error isolation (one tag throws, others keep working), timeout isolation, Historize toggle, ChangeTriggered=false ignore, reload cleans subscriptions, Dispose releases resources, SetVirtualTag fires observers, type coercion, 10k deep graph no stack overflow, initial-data callback, Unsubscribe stops events. Fixed two bugs during implementation. Monitor.Enter/Exit cannot be held across await (Monitor ownership is thread-local and lost across suspension) — switched to SemaphoreSlim. Kahn edge-direction was inverted — for dependency ordering (X depends on Y means Y comes before X) in-degree should be count of a node own deps, not count of nodes pointing to it; was incrementing inDegree[dep] instead of inDegree[nodeId], causing false cycle detection on valid DAGs. Full Phase 7 test count after Stream B: 99 green (63 Scripting + 36 VirtualTags). Streams C and G will plug engine + source into live OPC UA dispatch path.

Phase 7 Stream A.3 — ScriptLoggerFactory + ScriptLogCompanionSink. Third of 3 increments closing out Stream A. Adds the Serilog plumbing that ties script-emitted log events to the dedicated scripts-*.log rolling sink with structured-property filtering AND forwards script Error+ events to the main opcua-*.log at Warning level so operators see script failures in the primary log without drowning it in Debug/Info script chatter. Both pieces are library-level building blocks — the actual file-sink + logger composition at server startup happens in Stream F (Admin UI) / Stream G (address-space wiring). This PR ships the reusable factory + sink + tests so any consumer can wire them up without rediscovering the structured-property contract.
ScriptLoggerFactory wraps a Serilog root logger (the scripts-*.log pipeline) and .Create(scriptName) returns a per-script ILogger with the ScriptName structured property pre-bound via ForContext. The structured property name is a public const (ScriptNameProperty = "ScriptName") because the Admin UI's log-viewer filter references this exact string — changing it breaks the filter silently, so it's stable by contract. Factory constructor rejects a null root logger; Create rejects null/empty/whitespace script names. No per-evaluation allocation in the hot path — engines (Stream B virtual-tag / Stream C scripted-alarm) create one factory per engine instance then cache per-script loggers beside the ScriptContext instances they already build. ScriptLogCompanionSink is a Serilog ILogEventSink that forwards Error+ events from the script-logger pipeline to a separate "main" logger (the opcua-*.log pipeline in production) at Warning level. Rationale: operators usually watch the main server log, not scripts-*.log. Script authors log Info/Debug liberally during development — those stay in the scripts file. When a script actually fails (Error or Fatal), the operator needs to see it in the primary log so it can't be missed. Downgrading to Warning in the main log marks these as "needs attention but not a core server issue" since the server itself is healthy; the script author fixes the script. Forwarded event includes the ScriptName property (so operators can tell which script failed at a glance), the OriginalLevel (Error vs Fatal, preserved), the rendered message, and the original exception (preserved so the main log keeps the full stack trace — critical for diagnosis). Missing ScriptName property falls back to "unknown" without throwing; bypassing the factory is defensive but shouldn't happen in practice. Mirror threshold is configurable via constructor (defaults to LogEventLevel.Error) so deployments with stricter signal/noise requirements can raise it to Fatal. 15 new unit tests across two files. ScriptLoggerFactoryTests (6): Create sets the ScriptName structured property, each script gets its own property value across fan-out, Error-level event preserves level and exception, null root rejected, empty/whitespace/null name rejected, ScriptNameProperty const is stable at "ScriptName" (external-contract guard). ScriptLogCompanionSinkTests (9): Info/Warning events land in scripts sink only (not mirrored), Error event mirrored to main at Warning level (level-downgrade behavior), mirrored event includes ScriptName + OriginalLevel properties, mirrored event preserves exception for main-log stack-trace diagnosis, Fatal mirrored identically to Error, missing ScriptName falls back to "unknown" without throwing (defensive), null main logger rejected, custom mirror threshold (raised to Fatal) applied correctly. Full Core.Scripting test suite after Stream A: 63/63 green (29 A.1 + 19 A.2 + 15 A.3). Stream A is complete — the scripting engine foundation, sandbox, sandbox-defense-in-depth, AST-inferred dependency extraction, compile cache, per-evaluation timeout, per-script logger with structured-property filtering, and companion-warn forwarding are all shipped and tested. Streams B through G build on this; Stream H closes out the phase with the compliance script + test baseline + merge to v2. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

Phase 7 Stream A.2 — compile cache + per-evaluation timeout wrapper. Second of 3 increments within Stream A. Adds two independent resilience primitives that the virtual-tag engine (Stream B) and scripted-alarm engine (Stream C) will compose with the base ScriptEvaluator. Both are generic on (TContext, TResult) so different engines get their own instances without cross-contamination.
CompiledScriptCache<TContext, TResult> — source-hash-keyed cache of compiled evaluators. Roslyn compilation is the most expensive step in the evaluator pipeline (5-20ms per script depending on size); re-compiling on every value-change event would starve the engine. ConcurrentDictionary of Lazy<ScriptEvaluator> with ExecutionAndPublication mode ensures concurrent callers never double-compile even on a cold cache race. Failed compiles evict the cache entry so an Admin UI retry with corrected source actually recompiles (otherwise the cached exception would persist). Whitespace-sensitive hash — reformatting a script misses the cache on purpose, simpler than AST-canonicalize and happens rarely. No capacity bound because virtual-tag + alarm scripts are config-DB bounded (thousands, not millions); if scale pushes past that in v3 an LRU eviction slots in behind the same API. TimedScriptEvaluator<TContext, TResult> — wraps a ScriptEvaluator with a per-evaluation wall-clock timeout (default 250ms per Phase 7 plan Stream A.4, configurable per tag so slower backends can widen). Critical implementation detail: the underlying Roslyn ScriptRunner executes synchronously on the calling thread for CPU-bound user scripts, returning an already-completed Task before the caller can register a timeout. Naive `Task.WaitAsync(timeout)` would see the completed task and never fire. Fix: push evaluation to a thread-pool thread via Task.Run, so the caller's thread is free to wait and the timeout reliably fires after the configured budget. Known trade-off (documented in the class summary): when a script times out, the underlying evaluation task continues running on the thread-pool thread until Roslyn returns; in the CPU-bound-infinite-loop case it's effectively leaked until the runtime decides to unwind. Tighter CPU budgeting would require an out-of-process script runner (v3 concern). In practice the timeout + structured warning log surfaces the offending script so the operator fixes it, and the orphan thread is rare. Caller-supplied CancellationToken is honored and takes precedence over the timeout, so driver-shutdown paths see a clean OperationCanceledException rather than a misclassified ScriptTimeoutException. ScriptTimeoutException carries the configured Timeout and a diagnostic message pointing the operator at ctx.Logger output around the failure plus suggesting widening the timeout, simplifying the script, or moving heavy work out of the evaluation path. The virtual-tag engine (Stream B) will catch this and map the owning tag's quality to BadInternalError per Phase 7 decision #11, logging a structured warning with the offending script name. Tests: CompiledScriptCacheTests (10) — first-call compile, identical-source dedupe to same instance, different-source produces different evaluator, whitespace-sensitivity documented, cached evaluator still runs correctly, failed compile evicted for retry, Clear drops entries, concurrent GetOrCompile of the same source deduplicates to one instance, different TContext/TResult use separate cache instances, null source rejected. TimedScriptEvaluatorTests (9) — fast script completes under timeout, CPU-bound script throws ScriptTimeoutException, caller cancellation takes precedence over timeout (shutdown path correctness), default 250ms per plan, zero/negative timeout rejected at construction, null inner rejected, null context rejected, user-thrown exceptions propagate unwrapped (not conflated with timeout), timeout exception message contains diagnostic guidance. Full suite: 48/48 green (29 from A.1 + 19 new). Next: Stream A.3 wires the dedicated scripts-*.log Serilog rolling sink + structured-property filtering + companion-WARN enricher to the main log, closing out Stream A.
