docs: record value-pipeline batching (plan 2026-08-15)
- docs/v2/Galaxy.Performance.md gains a "Value-path batching (2026-08-15)" section: the batch seams (IBatchSubscribable / PollGroupEngine onBatch -> AttributeValueBatchPublished -> AttributeValueBatchUpdate -> sink WriteValues with 512-chunked single-lock batches in the node manager), the invariants (#519 status codes verbatim, per-ITEM metering, Modbus deadband honored via the driver-filtered buffer, the ValueWriteBatchException partial-failure contract), the RealmKey re-key, and the pinned dispatcher's throughput 1 -> 100. - The plan doc gains a "Follow-ups (recorded, not implemented)" section: the PollGroupEngine unconditional-collection trap (a future per-tag filter in S7/AbCip/FOCAS would silently reintroduce the deadband-bypass bug), a two-level driverId -> (rawPath -> refs) routing map, null/empty guard consistency on the internal batch messages, a possible DriverHostActorLiveValueTests merge, and the pre-existing aborted-cycle tail-loss on the three unbuffered drivers. - tasks.json: all 13 tasks completed. CLAUDE.md needed no edit: its only statement in this area ("One driver publish for a RawPath fans (in DriverHostActor) to the raw NodeId AND every referencing UNS NodeId") is still true — batching changed the message granularity, not the fan-out semantics. Verification: dotnet build ZB.MOM.WW.OtOpcUa.slnx clean (0 errors, no new warning classes, zero warnings in any production file). 9 unit projects green, 3470 passed / 5 skipped / 0 failed: Core.Abstractions 305, Core 351+1s, Commons 348, Runtime 575+3s, OpcUaServer 424+1s, Modbus 399, S7 302, AbCip 410, FOCAS 356. No DB-backed suite was run — tests/Server/ZB.MOM.WW.OtOpcUa.Server.Tests does not exist, and nothing this branch touches is covered by the SQL-backed projects. |

fix(galaxy): publish an unrepresentable value as BadTypeMismatch, not a good null
Reverses the conservative call from the previous commit at the user's direction, and they were right: "surface it on a counter first" left the wire lying. An MXAccess event can carry Good quality while its payload is a kind MxValueDecoder has no mapping for, so the old behaviour published null-under-Good — which a client cannot tell apart from a genuine null reading. A value the gateway DID send would be consumed as a value it did not, with the only evidence in a log nobody is tailing. Bad data is the honest wire representation of lost data. BadTypeMismatch is an existing StatusCodeMap constant, deliberately reused rather than written inline: StatusCodeParityTests finds status constants by reflecting over Good/Uncertain/Bad-prefixed uint fields and checking them against the pinned SDK, so an inline literal would be invisible to that guard (Gitea #497, where 16 wrong constants had accumulated across 6 drivers exactly this way). Logging is now once per DISTINCT value kind rather than once per pump. The set is bounded by the MxValue oneof enum so a broken producer still cannot flood, but a second unrepresentable kind appearing later gets its own line — warn-once-per-pump would have silently swallowed it, which is the same class of bug as the null this commit fixes. The test's fixture matters more than its assertion: the undecodable event carries Quality = 192 (OPC DA Good), so a decoder that gave up silently would publish Good and fail. Paired with a positive control — a decodable value at the same quality must still publish Good — so it cannot be satisfied by a pump that marks everything Bad. Falsified by reverting the status to Good: the test reds, and only that test. Verified: 331 Galaxy tests green, Core.Abstractions 298 (the parity guard), solution builds 0 errors. Docs corrected in the two places that recorded the old decision as deliberate. |

feat(galaxy): handle the replay-gap sentinel and sparse-array values
Closes the two follow-ups left open by the MxGateway 0.2.0 bump. Reading the
gateway's own contract first changed what each of them is, and one of my earlier
claims was simply wrong -- both corrections are recorded below.
Replay gap
----------
A sentinel MxEvent carries family = UNSPECIFIED, so it fell through EventPump's
family switch into the default drop: we silently ignored a documented MUST ("you
missed events -- discard local state and re-snapshot"). It is now intercepted and
answered by re-issuing SubscribeBulk for every tracked subscription, since
MXAccess delivers an initial value per item on subscribe -- re-subscribing IS the
re-snapshot. It does not restart the event pump (the stream carrying the sentinel
is healthy, and the handler runs on that stream's own read loop, so disposing the
pump from there would deadlock on itself), it does not block the read loop, and
re-entry is gated so a burst collapses to one pass instead of a subscribe storm
per sentinel.
Handled on the READ loop, not in the dispatch loop, because everything past that
point is subject to newest-dropped channel pressure -- and "you missed events" is
the one signal whose loss is unrecoverable. Pinned by a test that fills the
channel and still expects the sentinel.
⚠️ This cannot fire in the shipped configuration, and I did not pretend otherwise
or paper over it by enabling resume. The gateway emits the sentinel only for a
stream opened with after_worker_sequence > 0; GatewayGalaxySubscriber passes 0,
which the gateway treats as "fresh stream, not a resume -- plain attach, no
replay, no sentinel". Enabling resume is a larger and genuinely delicate change:
the sequence is only meaningful within ONE gateway session, our reconnect
recreates the session, and replaying a remembered sequence against a fresh
session sets the server's live watermark ABOVE every event it is about to send --
silencing the stream instead of recovering it. That deserves its own change with
a live gate, which I cannot run from here.
Sparse arrays -- correcting the last commit message
---------------------------------------------------
I wrote that the bump "makes handling it possible" on the decode path. That is
wrong: MxSparseArray is documented write-only, the gateway expands it before
forwarding, and "the worker never receives or produces it". So the decode path
is unreachable by contract and the write path has no use for it either -- it is a
wire compaction for a WHOLE-array write, not a partial update (unmentioned
indices are RESET, deliberately, because the gateway cannot read-modify-write
without racing the provider). It is therefore the wrong primitive for an OPC UA
IndexRange write, which expects untouched elements preserved -- and WriteRequest
carries no IndexRange in the first place.
It is decoded anyway, as contract defence: the alternative if a future gateway
ever emits one is a silent null published under Good quality. Fill semantics
mirror the gateway's own SparseArrayExpander exactly (epoch for Time, empty
string, Integer widening to long[] when any element is int64) so a value that
round-trips through a write reads back as the same CLR array.
Also: the decoder is now total by contract, since it runs inside the dispatch
loop where an escaping exception kills dispatch for the life of the pump. A
malformed payload degrades instead of throwing.
A real defect found in the same code
------------------------------------
A stream the GATEWAY completes -- a closed or evicted session -- ends the RPC
without an error, so nothing threw, the supervisor was never notified, and the
pump exited silently. GetHealth() kept reporting Healthy, which also means the
#527 comms-loss watchdog could never trip, because it requires a non-Healthy
state. The driver went permanently deaf with no signal anywhere. This one is
live, unlike the two above. Now reported as a fault; the falsification control is
the existing CleanShutdown_DoesNotInvokeOnStreamFault, since our own disposal
also ends the stream and must NOT be reported.
Value kinds we cannot represent are now counted and warned once rather than
published as an indistinguishable null. The status is deliberately NOT downgraded
to Bad: nothing can reach that branch today, and changing what an OPC UA client
sees for a live shape is not a change to make without a gate. The counter exists
so the next person has evidence instead of a guess.
Verified: 330 Galaxy tests green (12 new), plus Galaxy.Browser 21, Runtime 558,
Core 351; full solution builds 0 errors with the warning census unchanged. Every
new test was falsified first -- disabling the gap interception reds 3 of 4 (the
throwing-callback test passes vacuously when the callback never runs, by
construction), disabling sparse decode plus the representability signal reds all
7 decoder tests, and both were restored and re-verified green.
Docs: the Galaxy.Performance invariant was stated as received = dispatched +
dropped + in-flight, which this breaks -- a sentinel is received but never enters
the channel -- so it now reads + replay_gaps. Galaxy.md gains the three
operational notes; DriverLifecycle.md records that "reaches a non-Healthy state"
is an obligation a driver can silently fail to meet, which is the general shape
of the clean-end bug.

docs(mesh): sweep for ClusterClient deletion — Dps|Grpc only, CentralContactPoints retired
Task 3.2 of the ClusterClient->gRPC migration. Sweeps the docs that still described the Akka ClusterClient transport as live, following its Phase 3 deletion (this branch): MeshTransport:Mode is now Dps (pair-local DPS) or Grpc (cross-mesh unary calls) only, ClusterClient fails validation loudly, CentralContactPoints is deleted (not superseded), and the split-topology validator requires exactly Grpc rather than ClusterClient. - docs/Configuration.md: rewrite the MeshTransport section — table, dark-switch/PSK-seeding prose, listener sharing (:4056 driver-role, :4055 admin-role), remove the "shipped dark, cutover pending" framing. - docs/Redundancy.md: replace the Dps/ClusterClient transport table with Dps/Grpc, fix the Phase 6 CentralCommunicationActor + validator bullets. - docs/Telemetry.md: fix stale ClusterClient cross-refs, add a note that the driver-role telemetry listener also hosts NodeCommandService. - docs/v2/config-db-schema.md: one-line "(retired: ...)" annotation on the historical AkkaPort/GrpcPort note — left as a historical record otherwise. - CLAUDE.md: rewrite "## Mesh command transport (MeshTransport)" for the post-deletion world (no ClusterClient/receptionist, per-node gRPC dial, fire-and-forget semantics unchanged) and fix two Phase 6 bullets. deferment.md has no mesh-transport mentions; left untouched. docs-only change; `dotnet build ZB.MOM.WW.OtOpcUa.slnx` stays green (0 errors) after the edit.

feat(acl): ApiKey entity + key format, and put Core on the server's graph (#520)
Stage 1b. Still no enforcement wired — this adds the credential model the identity cutover (stage 2) will read. ApiKey holds one principal per key, deliberately. The reason to separate keys from principals is so many keys share a grant set and rotating a key never touches an ACL row, and that holds with one principal per key since nothing stops two keys naming the same principal. A key belonging to several principals at once buys little and costs a join table. UserAuthorizationState.Principals stays a list, so adding it later needs no ACL-side change. ApiKeySecret is the security-critical half and is pure, so it is tested on its own: otua_<keyId>_<secret>, peppered HMAC-SHA256, FixedTimeEquals. Notes why a plain HMAC rather than an iterated KDF (the secret is 32 bytes of CSPRNG, and the call runs inline on session activation, which the SDK serializes server-wide behind its SessionManager event lock), and fails closed on an unset pepper rather than hashing under an empty key. Found and fixed a bug in my own first draft: the key id was url-safe base64, whose alphabet maps '/' to '_' — the very character TryParse splits on. Roughly one key in five would have had its id truncated at a random position, an intermittent auth failure reproducing only for SOME keys. The id is hex now, and the guard is falsified: reverting the alphabet reds both The_generated_key_id_never_contains_the_separator and, as a bonus signal, Two_generated_keys_never_collide, because truncated ids collide. ApiKeyId is NOT NULL, unlike the nullable NodeAclId precedent whose filtered unique index would admit two NULL ids. Fine for a config row, not for a credentials lookup key. OpcUaServer.csproj now references Core. Until now it did not, so IPermissionEvaluator was literally uncallable from the node manager — the place enforcement has to happen. No new transitive package surface. Schema doc updated for both, and its NodeAcl block flagged for pre-existing drift (it still documents the GenerationId column v3 dropped) without fixing it here. Core 247, OpcUaServer 364, Configuration 128 — all green. Claude-Session: https://claude.ai/code/session_015p7wGqy3YpZNCpDzTpGMKo |

refactor(drivers): delete GetMemoryFootprint / FlushOptionalCachesAsync (#525)
Both `IDriver` members had no production call site. Their only consumer was `MemoryTracking`, deleted with the driver-tier recycle machinery in #522, and `GetMemoryFootprint`'s doc-comment claimed "polled every 30s by Core" — which had not been true since v3, even before #522 removed the poller. Owner decision on #525 was (a) delete rather than (b) build the process-wide watchdog that would consume them. The driver-side implementations are in git history and were mostly reusable; what was always missing is the trigger, and a member nobody calls is how the misleading doc-comment survived this long. Removed from `IDriver`, all 12 driver implementations, and every test stub — plus the support code that existed only to feed them, which is the part a member-only deletion would have left behind as dead weight: - MTConnect's three per-entry byte-weight constants, its cached `ProbeModelDataItemCount`, and `CountDataItems` — a full device-tree walk run on every cache fill to populate a number with no remaining reader. - OpcUaClient's `_discoveredNodeCount` field and the discovery-pass write to it. - MQTT's `ApproxBytesPerAuthoredTag`. Two behavioural notes, neither a change in what the software does: - `AbCipTemplateCache` now has no production reset path. Its only caller was AB CIP's flush, which itself had no caller — so nothing changes except how visible the fact is. Recorded on the type, along with the correction that its comment's claim about a device `ReinitializeAsync` also flushing it was never true. A UDT redefined on a live controller keeps its stale shape until the driver instance is rebuilt. - MTConnect's `/probe` cache is still dropped, by `InvalidateProbeModel()` on an Agent restart. That is now `internal` rather than `private` so the tests which used the flush purely to empty the cache drive the real path instead — they now cover a case that actually occurs in production. Several unrelated doc comments cited `FlushOptionalCachesAsync` as the canonical CAS example and are repointed to it. Tests: the ones that existed only to assert on the removed members are deleted (3 OpcUaClient, 3 Galaxy, 2 MQTT, 1 MTConnect, 1 AbCip). Worth noting one was vacuous — `FlushOptionalCachesAsync_resets_footprint_counter` asserted a footprint of 0 before the flush and 0 after with no discovery in between, so it would have passed against a flush that did nothing at all. Full suite green except 7 failures verified identical on master before and after (4 AbLegacy integration with the compose profile down, 3 Host.IntegrationTests), checked by name rather than assumed. Docs corrected where they described this as live: `DriverLifecycle.md` (which carried the #525 placeholder), `drivers/AbCip.md`, `drivers/AbLegacy.md`, and `v2/driver-stability.md` — whose "polls this every 30 s" + per-driver `DriverConfig` memory budget were never built as written and are now banner-ed as design intent rather than description.

refactor(drivers): delete the inert driver-tier recycle machinery (#522)
The tier system was documented, operator-authorable, and inert. Deleted rather than activated,
because its premise is gone rather than merely unused.
"Tier C" meant a driver running out-of-process behind an IDriverSupervisor that could restart its
Host without tearing down the OPC UA session. No such process exists anywhere: Galaxy reaches
MXAccess over gRPC to the external mxaccessgw sidecar (PR 7.2 retired the in-process
Galaxy.Host/Proxy/Shared projects) and FOCAS has run in-process since its managed wire client
landed 2026-04-24. Consistently, IDriverSupervisor had ZERO implementations and there was nothing
for one to implement against.
The issue understated the inertness. It says the Tier-C-only protections never engaged, implying
the Tier A/B parts did. They did not: nothing constructs MemoryTracking, MemoryRecycle or
ScheduledRecycleScheduler outside their own unit tests, so the whole Core/Stability recycle layer
was dead — meaning option (a), "pass real tiers", was never a flag flip. It would have meant
writing the wiring that never existed AND arming it.
Deleted: MemoryTracking, MemoryRecycle, ScheduledRecycleScheduler, IDriverSupervisor, the
vestigial DriverTypeRegistry (referenced only by its own tests), and the RecycleIntervalSeconds
knob — which the AdminUI let an operator author and the parser validated while it configured
nothing.
DriverTier itself SURVIVES and is load-bearing: DriverResilienceOptions.GetTierDefaults supplies
the real per-capability timeout/retry/breaker policies via DriverFactoryRegistry.GetTier and
DriverCapabilityInvokerFactory. Only the isolation-and-recycle layer above it is gone.
Deliberately NOT deleted:
- WedgeDetector came along in the same directory and is equally dead in production, but it is
tier-agnostic and is not recycle machinery — it only shares the folder. Restored rather than
swept up in a decision that was not about it.
- IDriver.GetMemoryFootprint() and FlushOptionalCachesAsync() lose their only consumer here.
Removing them touches all 12 drivers and every test stub, so they are documented as
consumerless and filed as #525 instead of buried in this diff.
Compatibility: a deployed ResilienceConfig blob still carrying "recycleIntervalSeconds" parses
cleanly (unknown keys are ignored — guarded by a new test, because a blob that suddenly failed to
parse would fall back to tier defaults and silently discard the operator's real overrides), and
the AdminUI's preserve-unknown-keys bag keeps the key rather than rewriting stored config on an
unrelated edit.
The 01/U-6 knob-inertness guard carried an explicit carve-out admitting RecycleIntervalSeconds was
dormant and out of scope; that carve-out is now gone, so the expected set is literally what the
test's name claims.
Note: Host.IntegrationTests has 2 failures (DriverProbeRegistrationTests.is_idempotent,
PrimaryGateFailoverTests) — verified pre-existing by reproducing both on clean master

test+docs: retire the stale EquipmentTagsDarkBatch4 skips, guard the deploy-time
tag gate, and fix three silently-broken OpcUaClient integration tests
Continues working through deferment.md's remaining items.
SKIPPED TESTS (13 -> 0 for this reason). The skip said "dark until Batch 4";
Batch 4 shipped as v3.0 and RETIRED the equipment-tag path rather than lighting
it, so every one of them was waiting on something that had already happened and
gone the other way. Resolved individually rather than in bulk:
- REVIVED onto the raw/UNS shape (6): four DriverHostActor primary-gate cases,
the cluster-scoping rebuild, and the real-SDK dual-namespace materialisation
E2E. The behaviour never went dark, only the v2 seeding did.
- FOLDED into a live parity test (3): DeploymentArtifactRawUnsParityTests
already compared RawTagPlan record-equal and RawTagPlan carries array /
historize / alarm intent, so widening its corpus by two tags covers what
three empty placeholder suites had been promising. Those suites are deleted.
- DELETED (4): subjects genuinely retired -- equipment-namespace EquipmentTags,
and both dot-joint {{equip}}.X token suites (that resolver was deleted in
Batch 3; the slash-joint form is covered by DeploymentArtifactEquipRefParityTests).
Falsified, not assumed: removing the seeded UnsTagReference turns two revived
primary-gate tests red; re-homing the SITE-A node to MAIN turns the scoping test
red. Widening a parity corpus also needed direct value assertions -- parity alone
cannot distinguish "both seams right" from "both seams blind".
Runtime.Tests skips 13->3, OpcUaServer.Tests 4->1; all remaining are deliberate
EquipmentDeviceBindingRetired tombstones.
G-7 (deploy-time TagConfig gate). MQTT shipped an Inspect() nobody ever called;
now wired. Replaced the hand-maintained list with a reflection guard, because the
existing test enumerates driver types by hand and so guards renames but can never
notice a gap. NOTE: the first version of that guard was hollow -- it discovered
candidates via GetReferencedAssemblies(), which is circular, since the compiler
elides a reference nothing in the IL uses. Removing MQTT from the map also removed
its Contracts assembly from the manifest, and the guard passed green with the bug
reintroduced. Rewritten to scan the output directory; re-falsified and it now
fails naming MqttTagDefinitionFactory. Residual recorded at the code: Sql,
MTConnect, Calculation and OpcUaClient have no Contracts-side Inspect at all, so
the deploy gate stays weaker than the AdminUI's authoring gate for them.
OPCUACLIENT INTEGRATION TESTS (3 of 4 failing, on master too). Not fixture rot:
the simulator was healthy and Client.CLI read the very same node Good. v3 made the
driver resolve every reference through its authored RawTags table, so a bare
"ns=3;s=StepUp" fails LOCALLY at the resolver with BadNodeIdInvalid and never
reaches the wire -- the tests were exercising the unresolved-reference guard.
Fixed by seeding OpcPlcProfile.RawTags in the deploy artifact's TagConfig shape
and addressing by RawPath. 4/4 pass.
DOCS. Applied the Phase7* -> AddressSpace* rename across the four live docs
(historical bannered files deliberately untouched), resolving the three that are
not renames to their real members. Found en route that the earlier banner pass
missed three files: VirtualTags.md, OpcUaServer.md and ScriptedAlarms.md all
still presented the test-scaffolding GenericDriverNodeManager as the production
dispatch path. All three now carry the correction.

docs+ui(security): state plainly that node ACLs are not enforced (§8.1, #520)
deferment.md §8.1 asked for a decision: wire IPermissionEvaluator into the node manager, or say plainly that ACLs are not enforced. Decision: the latter. The evaluator stays in the tree; #520 tracks the wire-up. Verifying the claim turned up four things worse than the audit recorded: - docs/security.md, not ReadWriteOperations.md, was the highest-risk doc. It claimed an anonymous session is "default-denie[d] any node a session has no ACL grant for". The opposite holds: anonymous can Browse/Read/Subscribe/ HistoryRead the entire address space, and is refused writes and alarm acks only because it carries no roles. - Three of five documented data-plane role strings do nothing. OpcUaDataPlaneRoles declares exactly WriteOperate and AlarmAck; ReadOnly, WriteTune and WriteConfigure are compared against nowhere in src/. The doc called all five "exact, case-insensitive, and code-true". - ReadWriteOperations.md was fiction beyond the ACL claims. OnReadValue has zero occurrences in src/ — the documented read path did not exist. Reads never reach a driver: the node manager is push-model and the SDK serves a Read from the cached pushed value. WriteAuthzPolicy, _sourceByFullRef, _writeIdempotentByFullRef and IRoleBearer are likewise zero-hit, and CapabilityInvoker is not referenced by the OpcUaServer project at all. This file is rewritten rather than bannered. - v2-release-readiness.md claimed a whole enforcement layer shipped — FilterBrowseReferences, GateCallMethodRequests, MapCallOperation, AuthorizationBootstrap, Node:Authorization:* keys. None exist. Whatever landed on the v2 branch did not survive into the shipped tree. The UI change is the operative one: ClusterAcls.razor and AclEdit.razor now warn that a grant is saved and shipped in every deployment artifact but never evaluated, so an operator cannot author a deny rule believing it works. deferment.md gains a §9 execution log tracking §8 remediation. |

docs: source-verified deferment register + correct 17 drifted docs
Adds deferment.md — a source-verified inventory of new-driver status, all 17
open issues, in-code deferrals, open live gates and plan bookkeeping. Every
claim was checked against src/ and git, not against documentation.
Headline finding: three subsystems are authored, persisted and shipped but
never executed —
* Node ACLs: IPermissionEvaluator/TriePermissionEvaluator have zero
production consumers and OtOpcUaNodeManager never references them, yet
ClusterAcls.razor authors NodeAcl rows and ConfigComposer.cs:51 ships them
in every artifact. An authored deny rule has no effect.
* IRediscoverable / IHostConnectivityProbe raise into the void (#518/#507);
nothing ever writes a DriverHostStatus row.
* DriverTypeRegistry is vestigial, so no factory passes a tier and every
driver runs Tier A with the Tier-C protections dormant.
Also records the Calculation driver as picker-visible but unauthorable
(DriverConfigModal has no case) — the "registered but unauthorable" class
recurring after the Sql picker defect — and notes that no parity test guards
DriverConfigModal/DeviceModal, which is why it survived review.
Documentation corrections (source-verified):
* ReadWriteOperations.md claimed "a denied read never hits the driver" via
four types that do not exist in src/. Bannered + struck through; a security
review reading that page would have concluded a per-node ACL gate exists.
* CLAUDE.md: the Change Detection sentence was false (DriverHost consumes
nothing); the mesh Phase 4 and Phase 5 live gates and the auto-down 1-vs-1
gate had all PASSED; the ScriptedAlarmState table was already dropped.
* driver-expansion tracking: Modbus RTU and SQL poll are merged, not
pending — its command table would have made someone rebuild two shipped
drivers in a fresh worktree.
* drivers/README.md: dead DriverTypeRegistry paragraph, retired
SystemPlatform namespace kind, missing Sql + Calculation rows, missing
Modbus RTU-over-TCP transport.
* TwinCAT.md/Galaxy.md promised an address-space rebuild that never happens.
* Historian.md gained the #491 unproven-value-capture pointer.
* IncrementalSync.md and AddressSpace.md bannered as wholesale v2-era (the
rewrite is recorded as still owed, not done here); four v2 status docs
bannered as historical; three wrong-name-for-a-live-type fixes.
Left deliberately untouched: the secrets NoOpSecretReplicator line, which
makes a security claim and needs the real behaviour identified rather than a
rename.

feat(config): add ClusterNode.MaintenanceMode — the hatch the live gate proved missing
Phase 1 gate step 4 failed: setting Enabled = 0 to take a node out of service returns 422 ClusterEnabledNodeCountMismatch, because DraftValidator.ValidateClusterTopology requires the enabled-node count to equal ServerCluster.NodeCount. On a Warm/Hot pair — every cluster on the rig, and every cluster in the target topology — Enabled can therefore never be the maintenance hatch. The plan called step 4 "the check that makes step 3 acceptable to ship", so Task 3's behaviour change was not shippable as it stood: a node down for maintenance would block every deployment to its cluster. The two rules were each reasonable and contradictory together — the validator reads Enabled as "part of the declared topology", Phase 1 additionally read it as "expect an ack". Split the meanings rather than weaken either rule: Enabled part of the declared topology (validator, untouched) MaintenanceMode expected to participate now (coordinator + reconciler) Rejected alternatives: counting configured rather than enabled nodes (drops the guard against booting a pair into InvalidTopology); downgrading the rule to a warning (weakens a deploy gate for everyone); shipping with no hatch. Sabotage: dropping !n.MaintenanceMode from the coordinator query turns the new test red. It also asserts both nodes remain Enabled, so the fix cannot quietly regress to disabling the row after all. Configuration.Tests 95/95, ControlPlane.Tests 101/101, solution builds clean. Claude-Session: https://claude.ai/code/session_01GASWkNEi68FSCtvr6rLoEW |

docs(cluster): self-first seed ordering replaces the self-form fallback
docs/Redundancy.md's bootstrap section is rewritten around the mechanism that is
actually in force: which of Akka's two bootstrap processes runs is decided by
whether seed-nodes[0] is this node's own address, so the ORDER of Cluster:SeedNodes
is the fix, not a timer. Adds the per-process table, the shipped self-first
example, why the validator is conditional (site nodes are not seeds) and why it
matches PublicHostname rather than the 0.0.0.0 bind address.
The retirement is documented rather than erased: a new subsection explains that a
watchdog outside the join handshake cannot tell "no seed answered" from "a seed
answered and the join is in flight", and the

feat(focas): real FANUC 30i/31i-B PDU-v3 support (live-validated on a 31i-B)
First real FOCAS hardware contact (Makino Pro 5 / 31i-B @ 10.201.31.5). A full
v3 data-PDU capture corrected the initial diagnosis: the v3 block envelope is
identical to v1, so only specific payload structs / request math / one client
robustness gap were wrong — not "framing rewrites".
Fixes (all re-validated live through the fixed driver):
- version gate: accept inbound PDU {1,3}, keep emitting v1 (FocasWireProtocol).
- cnc_rdtimer: 8-byte {minute,msec} payload is little-endian (ParseTimer) — the
only decode with an in-range msec field.
- pmc_rdpmcrng: request range widened to the data-type byte width
(end = start + width - 1) so a Word/Long isn't truncated to 0 values
(was spurious BadOutOfRange); decode extracted to ParsePmcRange.
- cnc_rdsvmeter: per-axis LOADELM is 8 bytes (not 12) and names come from the
0x0089 block — ParseServoMeters fixes the misaligned 655360 garbage. Also the
"hang" was NetworkStream.ReadAsync not aborting a stalled socket: ReadExactlyAsync
now disposes the stream on cancellation so a stalled peer can't wedge a poll loop.
- cnc_rddynamic2: contract guard rejecting axis < 1 (driver poll already 1-based).
- FocasDriverProbe: run a real wire session (initiate + cnc_statinfo) instead of
degrading to Ok=true "TCP reachability only" when FWLIB is absent — a bare TCP
listener no longer reports HEALTHY.
cnc_rdparam (0x000e) is unsupported on this control — EW_FUNC across 14
request-framing variants x 4 known-present params; needs a reference FWLIB trace
or is restricted. Deferred (deployed config uses macros, not parameters).
Tests: FOCAS suite 234 green (+16), full solution builds 0 errors. Raw v3
captures checked in under tests/.../Fixtures/v3/. Capture tools under scripts/focas/.

docs: sync against recent code changes
Five doc-content updates after this session's code-review resolution sweep. No code touched; pure documentation drift correction. 1. docs/reqs/HighLevelReqs.md (HLR-007 — Service Hosting): Refreshed the deployment description from "three cooperating processes (Server, Admin, Galaxy.Host)" to "two cooperating Windows services (Server, Admin)". The legacy x86 TopShelf Galaxy.Host process was retired in PR 7.2 (2026-04-30); Galaxy access now flows through the in-process Tier-A GalaxyDriver talking gRPC to the sibling mxaccessgw gateway. Also called out decision #30 (AddWindowsService replacing TopShelf) inline. 2. docs/VirtualTags.md: - Line 9: "compiled via Microsoft.CodeAnalysis.CSharp.Scripting" replaced with the current pipeline (Microsoft.CodeAnalysis.CSharp regular compiler — Core.Scripting-008 / -016 retired the CSharpScript/ScriptRunner path). - Line 39: orphan-thread leak description rewritten. The CSharp.Scripting-era "underlying ScriptRunner keeps running on its thread-pool thread until the Roslyn runtime returns" is no longer accurate — the new pipeline binds the script as a regular C# Func<> delegate, so the leak is now "synchronous CPU-bound work on a pool thread" (same operator-visible effect, different mechanism). 3. docs/v2/plan.md decision #29 ("Galaxy Host is a separate Windows service"): Annotated both the decision body and the decision-log table row with "Reversed PR 7.2, 2026-04-30" + a one-line summary of the replacement architecture. The original reasoning is preserved as audit trail per the decision-log convention. 4. docs/v2/implementation/phase-7-scripting-and-alarming.md A.1: Added an Implementation note describing the Core.Scripting-008 / -016 supersession of the original CSharpScript pipeline. The historical record stays; the note points future readers at docs/VirtualTags.md "Compile cache" for the current contract. 5. docs/plans/alarms-over-gateway.md "Files" section under client regeneration: Updated the .NET regeneration instructions to point at the new ZB.MOM.WW.MxGateway.Contracts.csproj path. The old clients/dotnet/MxGateway.Client.csproj no longer exists in the sibling repo (restructure after this plan was written) and the vendored-binaries situation in src/Drivers/ZB.MOM.WW.OtOpcUa.Driver.Galaxy/libs/ is called out so a reader following the plan won't chase a deleted path. Verification: grep against docs/ for the pre-fix wordings ("three cooperating processes", "Galaxy.Host (TopShelf)", "ScriptRunner", the wrong BadDeviceFailure hex code 0x80550000) returns no hits.

fix(scripting): block ThreadPool/Timer/AssemblyLoadContext in sandbox
Core.Scripting-012 (High, Security) resolution.
The Core.Scripting-008 rewrite broadened the BCL references list from a
narrow allow-list to the full System.* + netstandard +
Microsoft.Win32.Registry set, delegating the security gate entirely to
ForbiddenTypeAnalyzer. Three categories of dangerous BCL types were
reachable from script source without a deny-list entry:
- System.Threading.ThreadPool — QueueUserWorkItem re-introduces the
background-fanout threat Core.Scripting-003 closed against
System.Threading.Tasks.
- System.Threading.Timer — schedules unbounded callback work that
outlives the per-evaluation timeout.
- System.Runtime.Loader.AssemblyLoadContext — loads arbitrary DLLs.
Defense-in-depth gap; invocation needs reflection (already denied)
but the load itself was reachable.
Fix:
- Added 'System.Runtime.Loader' to ForbiddenNamespacePrefixes
(preferred over type-granular per the recommendation so future BCL
additions to that namespace are denied by default).
- Added 'System.Threading.ThreadPool' and 'System.Threading.Timer'
to ForbiddenFullTypeNames — both live in System.Threading shared
with allowed primitives so they must be type-granular.
Regression tests added to ScriptSandboxTests:
Rejects_ThreadPool_QueueUserWorkItem_at_compile
Rejects_Timer_new_at_compile
Rejects_AssemblyLoadContext_at_compile
Docs:
docs/v2/implementation/phase-7-scripting-and-alarming.md decision #6
and the Sandbox-escape compliance-check row both updated to enumerate
the new entries per the Core.Scripting-009 doc-sync convention.
Two lower-impact suggestions from the finding's recommendation
(System.Console, CultureInfo.DefaultThreadCurrentCulture) were
intentionally not addressed and are recorded as accepted minor risks
in the resolution.
Verification: Core.Scripting.Tests 107/107 (was 104 + 3 new rejection
tests).

fix(scripted-alarms): reuse per-alarm evaluation scratch on the hot path
Core.ScriptedAlarms-009 resolution: replace the per-call Dictionary +
AlarmPredicateContext allocation with a per-alarm reusable AlarmScratch
held in _scratchByAlarmId, refilled in place under _evalGate on each
evaluation. The hot path no longer allocates per upstream tag change.
Why this matters:
On a busy line where many tags feeding many alarms change frequently,
the old BuildReadCache allocated a fresh dictionary + context on every
predicate evaluation — a steady stream of short-lived allocations the
GC eventually has to reclaim. With the reuse, the dictionary and
context are allocated once per alarm (on first evaluation) and refilled
in place across every subsequent re-eval.
Implementation:
- New private AlarmScratch class holds the reusable
Dictionary<string, DataValueSnapshot> read cache (pre-sized to the
alarm's Inputs.Count) and the AlarmPredicateContext that wraps it by
reference. The context observes refilled values without being
re-created.
- ConcurrentDictionary<string, AlarmScratch> _scratchByAlarmId on the
engine, cleared in LoadAsync alongside _alarms so a config-publish
drops the prior generation's scratch (Inputs / Logger may change).
- EvaluatePredicateToStateAsync looks up scratch via GetOrAdd, calls
the new RefillReadCache(Dictionary, IReadOnlySet) helper to clear +
repopulate the dictionary in place, then runs the predicate against
the reused context.
- BuildReadCache removed.
Safety:
Reuse is serialised under _evalGate which guarantees no two threads
ever observe the same scratch in a half-refilled state. The
AlarmPredicateContext is bound to the scratch dictionary by reference,
so the predicate's ctx.GetTag(path) sees the freshly-refilled values
rather than a stale snapshot.
Verification:
- All 66 ScriptedAlarms tests pass (was 63 — three new regression tests
locking the reuse contract).
- All 56 VirtualTags tests still pass (unchanged).
- All 104 Core.Scripting tests still pass (unchanged).
New tests in ScriptedAlarmEngineTests:
- Reevaluation_reuses_the_same_read_cache_dictionary — asserts
ReferenceEquals(scratch_before, scratch_after) across two
evaluations of the same alarm.
- Reevaluation_reuses_the_same_predicate_context — same, for the
context.
- LoadAsync_drops_the_prior_generations_scratch — asserts a config
publish wipes the prior scratch (so a stale Logger / Inputs can't
leak into the new generation).
Internal test hooks TryGetScratchReadCacheForTest /
TryGetScratchContextForTest added via the existing
InternalsVisibleTo for the tests project. Kept internal — not part of
the public engine surface.
Docs:
- docs/v2/Galaxy.Performance.md "Scripted-alarm engine" section
rewritten as "hot-path allocation reuse" documenting the new
contract + reuse safety reasoning + the three regression tests.
- code-reviews/Core.ScriptedAlarms/findings.md -009 flipped
Won't Fix → Resolved.
- code-reviews/README.md regenerated.

fix(core-scripted-alarms): resolve Low code-review findings (Core.ScriptedAlarms-003,006,008,010,011; -009 documented)
- Core.ScriptedAlarms-003: emit OnEvent OUTSIDE _evalGate by collecting
pending emissions during the gate-held section and flushing them after
release; eliminates re-entrancy deadlock the docs already promised.
- Core.ScriptedAlarms-006: track every fire-and-forget Reevaluate /
ShelvingCheck task in _inFlight; Dispose drains the set so the engine
no longer races store writes against teardown.
- Core.ScriptedAlarms-008: store comments as ImmutableList<AlarmComment>
so AppendComment is O(log n) instead of O(n).
- Core.ScriptedAlarms-010: document the deliberate input-quality
asymmetry (Uncertain drives the predicate, renders {?} in the message)
in docs/ScriptedAlarms.md and on MessageTemplate.Resolve remarks.
- Core.ScriptedAlarms-011: propagate the no-op reason through
TransitionResult.NoOp(state, reason) and log it from
ScriptedAlarmEngine.ApplyAsync.
- Core.ScriptedAlarms-009 (Won't Fix per recommendation): documented the
per-evaluation dictionary allocation in docs/v2/Galaxy.Performance.md
with a mitigation path if a future soak surfaces pressure.

feat(server): route OPC UA Part 9 shelve methods to ScriptedAlarmEngine (#24)
OneShotShelve / TimedShelve / Unshelve now reach the ScriptedAlarmEngine. Scripted-alarm condition nodes get a ShelvedStateMachine subtree created before alarm.Create so the stack wires each shelve method's dispatch handler; AlarmConditionState.OnShelve / OnTimedUnshelve route to the engine and mirror the result onto the OPC UA node via SetShelvingState. The three per-instance shelve method NodeIds are indexed so the Call gate resolves them to OpcUaOperation.AlarmShelve instead of falling through to generic Call. Engine dispatch is split into the node-free InvokeEngineShelve so the routing decision is unit-testable. Adds 9 unit tests; updates phase-7-status.md Gap 1 (only AddComment remains unwired) and the #24 entry in looseends.md. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

scripts+docs: Refresh-Services.ps1 for alarm-rig deploy refresh (PR D.1)
Seventeenth PR of the alarms-over-gateway epic (docs/plans/alarms-over-gateway.md). Lands the script that the plan calls for in Track D — the actual smoke-run validation on the dev rig (publish, restart, fire alarms, capture artifacts) remains operator work; this PR ships the automation that the operator drives. scripts/install/Refresh-Services.ps1 — single-shot refresh script. Designed to run elevated on the deploy host (DESKTOP-6JL3KKO today; production uses a separate runbook). The script: - Stops services in reverse-dependency order (OtOpcUa → OtOpcUaWonderwareHistorian → MxAccessGw) and force-kills any residual processes (avoids the publish-time MSB3027 file-lock the original install script hit). - Snapshots existing C:\publish trees to C:\publish\.backup-YYYY-MM-DD-HHMMSS\ for rollback (skip with -SkipBackup). - Builds + copies mxaccessgw worker (x86 net48) + server (net10.0) binaries from the sibling repo. - Publishes OtOpcUa Server + Wonderware historian sidecar from this repo. - Ensures OTOPCUA_HISTORIAN_ALARM_WRITE_ENABLED=true is set on the historian service env block (PR C.2 toggle). - Starts services in forward-dependency order with the inter-service waits the original install used. - Smoke-verifies (service status, listening ports 5120 / 4840 / 4841, recent log tails). Supports -WhatIf for dry-run inspection without touching the running services. docs/v2/dev-environment.md — new "Service Refresh — Refresh-Services.ps1" section between Credential Management and Test Data Seed.

Audit (three parallel agent passes) found 43 markdown files carrying stale references to the deleted Galaxy.Host/Proxy/Shared projects after the v2-mxgw merge. This commit lands the prioritized fixes. Track 1 — high-traffic in-place rewrites (3 files, ~454 lines deleted) - README.md (202 → 91 lines): drops .NET 4.8 / x86 / TopShelf install text; leads with the multi-driver .NET 10 server identity and points at scripts/install/Install-Services.ps1 and the parity rig. - docs/v2/driver-specs.md §1 Galaxy (~289 → ~66 lines): replaces the Tier-C out-of-process spec with a Tier-A in-process description matching the current GalaxyDriver code, with the four-section GalaxyDriverOptions JSON shape pulled verbatim from Config/GalaxyDriverOptions.cs. - docs/drivers/Galaxy.md (211 → 92 lines): full rewrite around the current Browse/Runtime/Health/Config sub-folders. Track 2 — historical banners (5 files) - lmx_mxgw.md, lmx_mxgw_impl.md, lmx_backend.md, docs/v2/Galaxy.ParityMatrix.md, docs/v2/implementation/phase-2-galaxy-out-of-process.md each get a "✅ Completed 2026-04-30 — historical record" banner block. lmx_mxgw.md also fixes two dead links (`docs/Galaxy.Driver.md` and `docs/v2/Galaxy.Driver.md`) → `docs/drivers/Galaxy.md`. Track 3 — v1 archive sweep (10 git mv + 1 new index + 2 in-place scrubs) - Moved 10 v1 docs under docs/v1/ preserving subpath structure: AlarmTracking, Configuration, DataTypeMapping, HistoricalDataAccess, Subscriptions (top-level); drivers/Galaxy-Repository, drivers/Galaxy-Test-Fixture; reqs/GalaxyRepositoryReqs, reqs/MxAccessClientReqs, reqs/ServiceHostReqs. - New docs/v1/README.md is the shared archive banner + per-file table. - docs/README.md repointed to the v1 paths and updated to reflect the v2 two-process deploy shape (Server + Admin + optional OtOpcUaWonderwareHistorian). - docs/v2/Galaxy.ParityRig.md got a historical banner + four inline scrubs marking the OtOpcUaGalaxyHost service / Driver.Galaxy.Host EXE / Driver.Galaxy.ParityTests project as deleted-in-PR-7.2. The repo's live-reading surface (README + CLAUDE.md + docs/v2/) now describes only the post-PR-7.2 architecture. v1 docs are preserved as a labelled archive under docs/v1/.

PR 7.3 tail — doc + memory housekeeping for retired Galaxy.Host
Closes the v2-mxgw migration's housekeeping debt now that PR 7.2 has retired the legacy projects + service. Repo docs: - CLAUDE.md: rewrote the Galaxy section + reference-impl + MXAccess documentation pointers; replaced .NET 4.8 x86 / COM apartment constraints with .NET 10 AnyCPU + a pointer to the gateway. Dropped the "Service hosting (Galaxy.Host)" library-preferences row. - docs/ServiceHosting.md: rewrote (was 156 lines of Galaxy.Host pipe IPC details). Now reflects the v2 process shape: OtOpcUa.Server + OtOpcUa.Admin + optional OtOpcUaWonderwareHistorian, with Galaxy access via the in-process driver → mxaccessgw. - docs/v2/dev-environment.md: scrubbed four Galaxy.Host references (TwinCAT/Galaxy.Host shared-host note; .NET 4.8 SDK row; install step #2; risks table). The .NET 4.8 SDK is now correctly framed as "optional, only needed when building the mxaccessgw worker". - mxaccess_documentation.md: deleted from the repo root (obsolete; the gateway repo is the canonical MxAccess API doc). Memory housekeeping (under ~/.claude/projects/.../memory/): - Retired: project_galaxy_host_service.md, project_galaxy_host_installed.md, reference_impl.md (the LmxProxy Host MXAccess reference is no longer the design pattern this repo uses). - Revised: project_overview.md (now describes the .NET 10 + mxaccessgw shape), project_aveva_platform_installed.md (AVEVA still required on the dev box but consumed by the gateway worker, not by anything here), project_galaxy_via_mxgateway.md (post-7.2 state — flagged as the only Galaxy backend), project_server_history_alarm_subsystems.md (per-driver fallbacks retired in PR 7.2). - MEMORY.md index updated to match.

docs: drop soak + 2-week-pilot as PR 7.2 preconditions
The parity matrix gate is the precondition for retiring the legacy Galaxy projects. The 24h × 50k soak run and 2-week production pilot were sketched in early planning as additional safety nets but aren't operationally applicable for this deployment — there's no separate production fleet to pilot against, and the soak harness's value is as ongoing diagnostic infrastructure (still shipped in PR 6.4) rather than a one-shot release gate. PR 7.2's only remaining precondition is the matrix being fully green or carrying documented accepted-deltas — verified 2026-04-30 on the dev rig: 14 passed / 1 skipped / 0 failed. Affected: - docs/v2/Galaxy.ParityMatrix.md "Outstanding deltas" — flips to "PR 7.2 is unblocked" - docs/v2/Galaxy.ParityRig.md "After the rig is green" — drops the three-step soak+pilot flow, keeps only the matrix-doc bookkeeping follow-up - lmx_mxgw_impl.md PR 7.2 "Depends on" — replaces "fully soaked" with the matrix-green precondition + the verification date Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

parity: matrix fully green on dev rig (2026-04-30)
End-to-end run on the live ZB galaxy with mxaccessgw on http://localhost:5120: 14 passed / 1 skipped / 0 failed in 18m53s. PR 7.2's matrix-gate condition met. Three resolution patches in this commit; the matrix doc records the new state. 1. Discoverer: defensive `[]` array-suffix strip ---------------------------------------------------- The gw's GalaxyRepository.cs:173-175 appends `[]` to array-typed full_tag_reference values, but MxAccess COM IInstance.AddItem doesn't accept `[]`-suffixed addresses. GalaxyDiscoverer.StripArraySuffix removes the suffix client-side so SubscribeBulk / Read / Write paths see the canonical form. Tracked in mxaccessgw/requirements-array-suffix-fix.md; this workaround is removed when the gw fix lands. 2. WriteByClassification: pin status class, not exact code --------------------------------------------------------- Legacy MxAccessGalaxyBackend.WriteValuesAsync flat-maps every failure to BadInternalError (0x80020000); mxgw's GatewayGalaxyDataWriter.TranslateReply uses MxStatusProxy.RawDetectedBy to distinguish gw-layer faults (BadCommunicationError, 0x80050000) from MxAccess HRESULT faults. Both yield Bad-status — the parity invariant is the status class (Good/Uncertain/Bad), not the exact code. Both write tests now use AssertStatusClassMatches; legacy mapping retires alongside GalaxyProxyDriver in PR 7.2. 3. BrowseAndReadParity Read scenario: drop CLR-type assertion ------------------------------------------------------------ Legacy returns the raw VARIANT (e.g. byte[]) for an attribute that hasn't received its first value cycle from MxAccess yet, while mxgw returns the typed value (Single, Int32, etc.). Once a real value is written or scanned, both converge. Pinning CLR-type equality across the uninitialized window adds noise without a real parity invariant — the StatusCode-class assertion already covers the "did the read succeed" question. The test still pins StatusCode-class parity per scenario. 4. Galaxy.ParityMatrix.md — first-rig results captured ----------------------------------------------------- Per-row status flipped from "n/a unverified" to actual green / yellow / deferred outcomes from this run. Four new accepted-deltas added (read-value CLR type, write-status code mapping, single-platform ScanState scope, gw `[]` suffix workaround), bringing the total to nine. Outstanding deltas section flipped to "none as of 2026-04-30." Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> |

docs: parity rig — concrete mxaccessgw setup recipe
Replaces the placeholder "configure an API key per gateway.md" with the actual commands that worked end-to-end on this dev box: - Build both halves (Worker x86 net48, Server net10) - apikey init-db + apikey create-key with the seven scopes the parity test exercises (session:*, invoke:*, events:read, metadata:read) - Three env-var overrides at server startup — capturing real lessons learned standing the rig up: * Kestrel__Endpoints__Http__Url = http://localhost:5120 * Kestrel__Endpoints__Http__Protocols = Http2 (gRPC needs h2c on plain HTTP — without this flag the client gets HTTP_1_1_REQUIRED) * MxGateway__Worker__ExecutablePath = absolute path to the built worker (appsettings.json's relative path drops \net48 and the server can't resolve it) - Note that workers spawn lazily on first OpenSession, not at server startup — so port-listening is necessary but not sufficient evidence the gateway is healthy.

docs: provisioning recipes for parity rig via graccess-cli
Calls out the single-platform constraint on this dev box and the graccess-cli at C:\Users\dohertj2\Desktop\graccess as the way to configure the rest of the parity-rig Galaxy shape: - ScanState probe parity (multi-platform) is deferred to a customer rig — not feasible on this dev box. PR 7.2 gate accepts "n/a, deferred" on those rows because PR 4.7's unit tests already pin the state-decoder + member-tracking logic. - Per-row provisioning recipes for the five ⚙-scriptable rows: FreeAccess/Operate UDA, Configure/Tune UDA, value-change source (recommend external write-loop over template surgery), $Alarm* extension, History extension. All against a reserved OtOpcUaParityTest sandbox UDO so plant-relevant objects stay untouched. - Trailing deploy + Galaxy.Host restart so MxAccess picks up the change before re-running the matrix.
