Joseph Doherty d0af884760 feat(scripts): add the Alarms.CurrentAsync() read accessor for site scripts
MES alarm-status API §5.2 (docs/plans/2026-06-30-mes-alarm-status-api.md,
Phase 1 tasks 2-4). Site `Call` scripts had NO way to read alarm condition
state: the `Alarm` global exists only inside an on-trigger handler and
describes the one alarm that fired, and native mirrored conditions were
reachable only from the Debug View. That gap blocked the CvdReactor
SimpleAlarmStatus/AlarmStatus scripts entirely -- they cannot be written
without it. `Alarms.CurrentAsync()` closes it.

The data was already local: the script runs inside its own Instance Actor's
context, so this is a LOCAL Ask -- the same mechanism attribute reads use, no
cross-cluster hop. A dedicated GetAlarmSnapshotRequest/Response is used rather
than reusing DebugSnapshotRequest, which would materialise every attribute
value on every alarm poll; both are served from the same
BuildAlarmStatesSnapshot(), so the script view and the operator's Debug View
can never disagree.

Deliberate shape decisions:
  - NOT scope-prefixed, unlike Attributes. Alarm identity is not a
    scope-relative attribute name (computed alarms are keyed by configured
    name, native conditions by a source-supplied reference), so prefixing
    would hand a composed script a silently truncated list.
  - Read-only. Native alarms are a read-only mirror of the source (no
    ack-back), so no acknowledge/shelve operation is exposed.
  - Placeholder rows are NOT pre-filtered: a caller must be able to tell
    "binding configured and quiet" from "binding unknown". The documented
    filter is `Active && !IsConfiguredPlaceholder`.
  - ScriptAlarm lives in Commons so the runtime accessor and the compile-only
    surface project to the SAME type -- a script binding at the design-time
    gate binds identically at the site. Condition is the authority for
    active/acked/severity, so one filter expression works across computed and
    native alarms.

Mirrored on BOTH design-time surfaces. ScriptCompileSurface is covered by the
reflection parity guard (AlarmsAccessor added to its mirror pairs). The Central
UI Test-Run SandboxScriptHost is the third, hand-maintained mirror that the
parity test cannot reach (Central UI does not reference Site Runtime); without
it the design page would false-flag CS1061 on scripts the deploy gate accepts.
It throws a labelled ScriptSandboxException at run time -- there is no central
route to per-instance alarm state, and returning an empty list would read as
"nothing is in alarm", which is worse than an error.

ScriptTrustPolicy needs NO change, and the reason is structural rather than
incidental: the trust boundary is a deny-list over API roots, not an allow-list
of context members. A test pins that no ForbiddenScopes entry prefixes the
Commons script-surface namespace, so a future deny-list entry cannot silently
make ScriptAlarm untouchable.

Tests: 6 accessor cases (Ask contract, full native projection incl. AckTime,
unacked, computed-alarm derivation, placeholder visibility, scope-independence),
2 InstanceActor snapshot cases incl. equality with the Debug View row set, the
full MES script shape compiling against ScriptCompileSurface, 2 trust cases,
and a sandbox diagnose-clean case reading every projected ScriptAlarm field.

Joseph Doherty 01bcca992c feat(alarms): thread an additive AckTime through the native-alarm mirror
MES alarm-status API §6.4 (docs/plans/2026-06-30-mes-alarm-status-api.md,
Phase 1 task 1). MES needs a real AckDT for a triggered alarm, and the mirror
carried acked-vs-unacked but never WHEN. AckTime now rides the whole path:
DCL transition -> AlarmStateChanged -> gRPC AlarmStateUpdate -> site SQLite.

Stamping rule, identical on both protocols: non-null ONLY while the condition
is active AND acknowledged. That single predicate yields all three required
behaviours -- null while unacked, cleared on re-raise (a re-raise arrives
unacknowledged), and no phantom ack on a return-to-normal. The last one is
load-bearing for MxGateway, which maps INACTIVE to Acknowledged = true; without
the active check every clear would claim an ack the system never observed.

Provenance is honest, never fabricated:
  - OPC UA A&C supplies a TRUE ack instant, so we now select it:
    AcknowledgeableConditionType/AckedState/TransitionTime at SelectClause
    index 18, APPENDED so the positional reads at 0-17 keep their meaning.
    Servers that omit the field fall back to the event's own Time.
  - MxAccess Gateway supplies none, so the ack transition's own timestamp is
    used -- accurate to when the system SAW the ack. An ACTIVE_ACKED
    re-subscribe snapshot restores one from LastTransitionTimestamp rather
    than dropping it.
The decision lives in pure mappers (Opc/Mx AlarmMapper.DeriveAckTime), so it is
unit-tested with no live server or gateway.

Additive-only throughout: init-only property on AlarmStateChanged, trailing
optional positional on NativeAlarmTransition (all 14-arg call sites untouched),
proto field 24 (never reusing a number) regenerated via docker/regen-proto.sh
sitestream with the csproj diff verified empty.

Persistence rides native_alarm_state's existing metadata_json blob rather than
a new column -- deliberately. That table is RegisterReplicated in
SiteLocalDbSetup and LocalDb builds its CDC triggers from the column list at
registration time, so an additive JSON property changes no schema, no triggers
and no replication contract; metadata_json is exactly the extension point UA4
introduced for this. Rows written before the field deserialize it as null.

Tests: 4 OPC UA + 6 MxGateway mapper cases, 3 NativeAlarmActor (emit,
failover rehydrate, pre-AckTime row), 1 proto round-trip incl. the null case,
4 Commons additive/back-compat. The OPC UA SelectClause count lock-in moves
18 -> 19 with an index-18 assertion -- intended, the clause is appended, which
is precisely what that guard exists to make visible.

Joseph Doherty 0c9dffed78 fix(transport): flush created-site ids before the connection pass — create-missing import failed FK 547 on real SQL Server
Caught live 2026-08-01 importing a bundle into the empty env2 cluster: a
create-missing Site has Id == 0 until SaveChanges on a relational provider,
and ApplyDataConnectionsAsync stamps DataConnection.SiteId as a raw scalar
(no navigation, no EF fix-up), so the insert violated
FK_DataConnections_Sites_SiteId. Every importer integration test runs on
the EF in-memory provider, which assigns ids eagerly on AddAsync — the
exact masking the in-code comment predicted. Fix: one SaveChangesAsync
between the site pass and the connection pass, riding the same outer
transaction (all-or-nothing preserved; the failed live import rolled back
cleanly). Regression test runs the create-missing path on SQLite
(CreateMissingSiteRelationalTests) — red without the fix, green with it.

Joseph Doherty 316153dc98 feat(centralui): hide OffsetPager on a single page, opt-in — NotificationReport enabled (M10 residual)
DECISION: a pager whose only two controls are permanently disabled is noise, so
the conventional behaviour ships — the bar is hidden when the result set is a
single page. NotificationReport, which raised the finding, opts in.

RATIONALE for opt-in rather than default-on. OffsetPager is shared, and its
summary span ("Page N of Y · T total") doubles as the ONLY total-count readout
on ConfigurationAuditLog — auto-hiding there would silently delete the result
count for every query returning under a page, and the existing Playwright
fixture asserts "3 total" on exactly such a query. So the behaviour lives in the
shared component (reusable for the next consumer) behind HideWhenSinglePage,
default false, which keeps every current consumer byte-identical.

The guard fires only when single-page-ness is POSITIVELY established:
PageCount <= 1 AND Page <= 1 AND !HasNextPage. A null TotalCount means the host
cannot count, so the bar renders — the controls never vanish while a further
page still exists.

NotificationReport's own Playwright pagination test seeds 51 rows (2 pages) and
is unaffected. 5 new bUnit tests cover hide-on-single-page, hide-on-empty,
show-on-multi-page, show-when-TotalCount-unknown, and the default-off path.

Joseph Doherty a506b19d17 refactor(centralui): migrate TemplateEdit's four page-embedded modals to the DialogService host (M10 residual)
TemplateEdit was the last page still hand-rolling its own modal chrome after
M10 — T34c only tokenized its backdrops. All four member-authoring forms
(Attribute, Alarm, Native Alarm Source, Script) now open through
IDialogService.ShowAsync, so the single DialogHost in MainLayout owns the
backdrop, focus trap, Escape and focus restoration.

Pattern copied from the already-migrated pages (MoveDataConnectionDialog +
Templates' Move/Rename dialogs): each body is its own component beside the page
taking a DialogContext<bool>, owning its form state, rendering validation and
server errors INLINE while staying open, and closing with Close(true) only once
the save succeeded — at which point the page reloads. An inline RenderFragment
would NOT have worked: DialogHost renders the captured fragment in its own tree,
so the page's StateHasChanged could never refresh it.

Persistence deliberately stayed on the page (it owns TemplateService, the
inherited-member rules, and the repository-direct native-source path) and is
reached through an OnSaveAsync delegate returning null on success or the message
to display. Behaviour preserved verbatim, including the List-attribute encode +
Decode round-trip check, the name/trigger-type read-only-on-edit rules, the
duplicate-native-source-name guard, and NormalizeExecutionTimeout.

TemplateScriptDialog keeps all four tab panels mounted (Monaco and the JSONJoy
island must not tear down on tab switch) and hosts the Test Run panel, which
needs the live unsaved editor buffer, so it injects ScriptAnalysisService
directly and cancels an in-flight run on dispose.

Extraction moved markup that three structural source-scanning tests pinned;
all three were repointed at the new files rather than weakened:
  - TemplateNativeAlarmSourceEditorTests (+ a new test asserting the form is
    host-mounted and the body renders no chrome of its own)
  - AttributeListEditorTests (list-editor reveal now in the dialog body)
  - TestRunWarningTests (Real I/O warning travelled with the script panel)

Build 0/0; CentralUI.Tests 973/973 green.

Joseph Doherty fdfd5e1b27 feat(centralui): TreeView full WAI-ARIA keyboard navigation (M10 residual R7)
TreeView<TItem> handled only Enter/Space on the chevron; the tree itself was
unreachable by keyboard. Implements the WAI-ARIA tree pattern:

- Roving tabindex on li[role=treeitem] — exactly one node is tabbable, so the
  whole tree is a single Tab stop. Target resolved per render: last-focused node
  while still visible -> SelectedKey -> first visible node. Browser focus follows
  via a per-node ElementReference + FocusAsync in OnAfterRenderAsync, guarded by
  the same JSException/JSDisconnectedException/InvalidOperationException triple
  the context-menu focus already used (a no-op under bUnit).
- ArrowDown/ArrowUp move between VISIBLE nodes; ArrowRight expands a collapsed
  branch else moves to first child; ArrowLeft collapses an expanded branch else
  moves to parent; Home/End jump to first/last; Enter/Space activate through the
  SAME path a click takes (OnContentClick / OnCheckboxToggle) so selection
  semantics never diverge between input modes.
- ARIA: aria-level, aria-posinset, aria-setsize added; aria-selected now renders
  true/false on selectable+checkbox trees and stays absent on non-selectable ones.
- Event scoping: @onkeydown:stopPropagation on the li, chevron, checkbox and
  content slot, so nested nodes do not double-handle and consumer controls inside
  NodeContent keep their own key handling. Browser scroll-on-Space/Arrow is
  suppressed by a minimal NATIVE inline onkeydown on the root ul, targeted at
  treeitems only — Blazor's preventDefault directive is all-or-nothing per
  element, so on the li it would trap Tab and cancel Enter/Space on consumer
  buttons. No CSP is configured, so the inline handler runs.

BuildVisibleNodes() mirrors RenderNode's visibility rules and must stay in step.

Tests: 31 new bUnit tests in TreeViewKeyboardNavigationTests; the 47 existing
TreeView tests are unchanged and still green. Docs: new keyboard/a11y section in
docs/components/TreeView.md.

Joseph Doherty 8aa6bf2270 fix(audit): populate ParentExecutionId on alarm-triggered script runs
M5.4 T4 threaded a `parentExecutionId` parameter through
AlarmActor.SpawnAlarmExecution → AlarmExecutionActor → ScriptRuntimeContext,
but every call site passed null — so alarm on-trigger runs were silently always
execution-tree roots, contradicting the "tag-cascade coverage is complete"
claim in CLAUDE.md and Component-AuditLog.md.

Source the id where a spawner genuinely exists: a static attribute write issued
by a site script (`Instance.SetAttribute`) or by an inbound API request
(`Route.To(...).SetAttributes(...)`, whose ParentExecutionId was already carried
to the site and then dropped). The id rides site-locally through three additive,
nullable fields — no wire, proto or central schema change:

  ScriptRuntimeContext.SetAttribute / RouteToSetAttributesRequest.ParentExecutionId
    → SetStaticAttributeCommand.SourceExecutionId
    → AttributeValueChanged.SourceExecutionId   (InstanceActor static-write path)
    → AlarmActor.SpawnAlarmExecution → AlarmExecutionActor → ScriptRuntimeContext

All four computed trigger types participate. Expression triggers evaluate off
the dispatcher, so the writer of the newest value folded into the snapshot is
captured *with* the snapshot and echoed home on ExpressionEvalResult /
ExpressionEvalFailed — a change arriving mid-flight cannot mis-attribute the
raise.

Deliberately still roots (documented, not deferred): alarms fired by Data
Connection Layer values (external device data has no spawning execution — this
includes the device echo of a script write to a *data-sourced* attribute, so
only static writes cascade), and ScriptActor value-change/conditional/
expression/timer trigger runs (a timer tick has no spawner; a WhileTrue/interval
run has no single identifiable write).

Tests: new SiteRuntime.Tests/Actors/AlarmCascadeParentExecutionTests pins all
three hops — SetAttribute stamps the run's ExecutionId, InstanceActor publishes
it on the change (and publishes null when absent), and ValueMatch/HiLo/
Expression alarms parent the on-trigger run to the writer while a DCL-originated
change leaves it a root.

Docs: CLAUDE.md and Component-AuditLog.md corrected from "complete" to the true
behaviour; Component-SiteRuntime.md gains an "Audit correlation of an on-trigger
run" section with the hop table and the by-design root cases.

Joseph Doherty 88638d774a feat(cli,management): close area-move and template-folder CLI parity gaps
Two verified-absent parity gaps between the service layer and the CLI /
ManagementActor command surface, both left as follow-ups by the 2026-05-11
design plans.

(1) area move. AreaService.MoveAreaAsync had existed since the deployment
topology page shipped but was reachable only from the Blazor UI. Adds
MoveAreaCommand(AreaId, NewParentAreaId?) to Commons, a ManagementActor
dispatch arm delegating straight to AreaService.MoveAreaAsync (not-found /
self-parent / descendant-cycle / cross-site / name-collision all surface as
the standard curated ManagementCommandException failure response; the service
writes its own "Move" audit row), and the CLI verb `site area move --id
[--parent-id]`. Omitting --parent-id moves the area to the site root, matching
the command's nullable NewParentAreaId. The command carries the SAME any-of
[Designer, Deployer] gate as CreateArea/UpdateArea/DeleteArea (arch-review C6):
re-parenting is the same structural authoring act, exposed on the same two
surfaces. Placed under the existing `site area` group rather than a new
top-level `area` group, alongside its create/update/delete siblings.

(2) template folder verbs. The five folder management commands have been
handled by ManagementActor since the folder-hierarchy plan, but the promised
CLI surface was never written. Adds `template folder
list|create|rename|move|reorder|delete` mapping 1:1 onto ListTemplateFolders /
CreateTemplateFolder / RenameTemplateFolder / MoveTemplateFolder /
ReorderTemplateFolder / DeleteTemplateFolder. --parent-id is omitted to target
the tree root; --direction takes the lowercase literals up/down, validated at
parse time by AcceptOnlyFromAmong (same case-sensitive contract as the audit
--channel/--kind/--status options).

Follow-on updates: the frozen authorization matrix gains its MoveArea entry
(reflection-driven, so a missing entry would have failed CI); CommandTreeTests
pins both new verb sets plus the omit-parent-id-means-root parse behaviour and
registry round-trips; ManagementActorTests covers the MoveArea role gate and
the delegate-to-service success/root/cycle/not-found paths; the CLI README and
Component-ManagementService.md document the new surface (the latter also gained
the previously-undocumented ReorderTemplateFolder); both plan docs' follow-up
lines are marked done.

Joseph Doherty a26d6ba317 feat(central-ui): native-alarm-source CSV import on InstanceConfigure
The Native Alarm Source Overrides card had no bulk affordance — the CSV path
shipped CLI-only (instance native-alarm-source import --file), so the UI could
only retarget one source at a time inline.

Adds a second InputFile on that card, mirroring the attribute importer's UX
(hidden input behind a button-styled label, 512 KB cap, success/error alert
with the per-line error list, toast). Parsing reuses the SHARED
NativeAlarmSourceOverrideCsvParser — the exact parser the CLI uses — and the
new pure InstanceConfigure.BuildNativeAlarmSourceCsvImport applies the same
batch rules the server enforces in
ManagementActor.HandleSetInstanceNativeAlarmSourceOverrides: the source must
resolve, must not be template-locked, and may appear at most once; any error
rejects the whole file and applies nothing.

Semantics match the CLI: merge, not full replace — sources absent from the
file keep their existing override, a blank field keeps the inherited value,
and an all-blank row clears that source's override (equivalent to the CLI's
all-null override row, without leaving a dead row behind).

Persistence reuses the inline editor's path: SaveNativeOverride's upsert body
is extracted to UpsertNativeOverrideCore (no SaveChangesAsync inside), so the
import commits the validated batch in one SaveChangesAsync — no new server
method, no duplicated parsing.

Tests: InstanceConfigureNativeAlarmCsvImportTests (9) — happy path, blank-field
inheritance, all-blank clear, merge semantics, unknown/locked/duplicate source
and parser-error rejection, plus structural pins on the InputFile wiring.
Docs: Component-CentralUI.md native-alarm-source card gains the import bullet.

Joseph Doherty 2d03f2d507 fix(site-runtime): reconcile artifact deletions on apply — central deletes no longer orphan site rows
The artifact apply (DeploymentManagerActor.HandleDeployArtifacts) was
upsert-only, so deleting an external system (or shared script, DB connection,
data connection) centrally never removed the site's SQLite row — a deleted
external system stayed callable from site scripts forever. Central always
ships the COMPLETE set of each artifact class (ArtifactDeploymentService
GetAll* snapshots; the wire's presence-tracking wrapper lists preserve
null-vs-empty), so the site now applies upsert-then-reconcile: after storing
the incoming set, SiteStorageService.DeleteRowsExceptAsync removes any stored
row absent from it, per artifact table. A null list still means 'field not
shipped' and touches nothing.

Runtime cleanup rides along: a reconciled-away shared script is unregistered
from the compiled SharedScriptLibrary (a stale delegate would stay callable
until restart), and a removed data connection is evicted from the DCL hash
cache and its live connection actor stopped via the previously-caller-less
RemoveConnectionCommand — both on the actor thread via the extended
ApplyArtifactDataConnectionsToDcl message. All four tables are
RegisterReplicated, so the deletes reach the standby as ordinary CDC row
tombstones.

Tests: storage-level reconcile per table (incl. empty-set-deletes-all and
idempotency) in ArtifactStorageTests; actor-level pins in
DeploymentManagerActorTests (orphan delete, null-set no-op, library
unregistration, DCL stop for the removed connection only). Docs:
Component-DeploymentManager + Component-SiteRuntime record the
full-set/reconcile semantics.

Joseph Doherty 63c16d6912 refactor(comm): retire ClusterClient naming after the gRPC cutover
Phase 4 of the ClusterClient -> gRPC migration deleted the Akka transports
but left the naming behind: `ClusterClientSiteAuditClient` was transport-
agnostic and worked unchanged, so it survived the deletion under a name
that now describes a transport the repo no longer has. Same for a scatter
of doc-comments still framing gRPC as "the new transport" beside an Akka
one that is gone.

Renames it to `SiteCommunicationAuditClient` (and its test file) and
rewrites the stale comments to describe the single transport that exists.
Also tightens CLAUDE.md: drops the self-describing directory listing and
the 27-component enumeration in favour of the non-obvious parts only.

Behaviour-neutral: names and prose only. Recorded as the Phase 4
follow-up in docs/plans/2026-07-22-clusterclient-to-grpc-plan.md.

Joseph Doherty b3dc17a5fe Merge feat/site-node-health: serve health on site nodes + shared active-node check (Health 0.3.0) 2026-07-24 13:35:27 -04:00
Joseph Doherty 1c9159a7ce fix(tests): qualify Health page type — Communication.Health namespace shadowed it 2026-07-24 13:35:24 -04:00
Joseph Doherty 5d4853a1f0 refactor(health): adopt the shared active-node check (Health 0.3.0)
OldestNodeActiveHealthCheck existed because the shared ActiveNodeHealthCheck
selected by cluster leadership (review 01 [High]): leadership is address-ordered
and diverges from singleton placement after a restart, and during a partition
both sides compute themselves leader so Traefik served both. Health 0.3.0 makes
the shared check age-based — it is now this host's own rule, promoted — so the
private copy is deleted and central registers the shared type.

ActiveNodeEvaluator, the "THE single definition of active node" this repo already
maintained, now delegates to the shared ClusterActiveNode rather than
re-implementing it. That keeps the delivery gate, the heartbeat IsActive stamp,
the inbound-API gate and the /health/active tier on one rule, and it means the
rule is shared with OtOpcUa, which had independently written a third copy.
Communication takes a ZB.MOM.WW.Health.Akka reference for it; the layering
trade-off is recorded at the PackageReference.

SitePairActiveNodeHealthCheck is deliberately KEPT. It is not a duplicate of the
rule — it is a thin adapter over the site's own IClusterNodeProvider, which
scopes to site-{SiteId} and is itself now backed by ClusterActiveNode. Registering
the shared check directly would have to re-derive the site role and would lose the
property that the tier and singleton placement come from the same provider.
Central stays unscoped: every central member competes for one active slot.

No behaviour change on any node — same rule, one implementation instead of two.

Verified: Host.Tests 439/439, Communication ActiveNode 2/2.

Joseph Doherty 248676ed16 feat(cluster): simultaneous-cold-start split-brain guard (#33)
Port OtOpcUa's bootstrap guard (lmxopcua d1dac87f) to ScadaBridge's
BuildHocon bootstrap. Both pair nodes are self-first seeds, so a true
simultaneous cold start (shared site power event) races FirstSeedNodeProcess
on both and forms two 1-node clusters that never merge.

Opt-in dark switch ScadaBridge:Cluster:BootstrapGuard:Enabled (default off,
guard-off behavior byte-identical). When on: BuildHocon emits an empty seed
list so Akka does not auto-join, and ClusterBootstrapCoordinator (IHostedService,
registered in both the Central and Site composition roots) picks the join order
from ClusterBootstrapGuard's pure decision core — the lower canonical host:port
is the founder (self-first, forms immediately); the higher node TCP-probes the
founder up to PartnerProbeSeconds and joins peer-first if reachable, else
self-first (cold-start-alone preserved). Decides before a single JoinSeedNodes,
never re-forms mid-handshake.

Review notes carried over: case-insensitive founder tie-break; fail-fast
validation of probe timings when enabled; higher-node-cold-start-alone covered
by a real-ActorSystem test. 21 unit + 5 real-cluster tests (incl. the headline
both-cold-start-together-form-one-cluster).

Joseph Doherty 47850c0f53 feat(health): serve MapZbHealth on site nodes
Site nodes served no health surface at all — gRPC on the HTTP/2-only listener and
/metrics on the HTTP/1.1 one — so nothing outside the cluster could ask a site
node whether it was ready or which half of the pair was active. The family
overview dashboard probes every instance the same way, and this is the one gap.

Three checks, registered in SiteServiceRegistration.Configure (not Program.cs, so
the composition-root tests that build this graph actually cover them) and mapped
by app.MapZbHealth() on the site's HTTP/1.1 listener (default :8084) alongside
/metrics:

  akka-cluster  [Ready]  the shared AkkaClusterHealthCheck. Also carries the
                         cluster-view data (leader/memberCount/...) the dashboard
                         reads, free with ZB.MOM.WW.Health 0.2.0.
  localdb       [Ready]  NEW SiteLocalDbHealthCheck — SELECT 1 through the
                         registered ILocalDb. Site has no EF context; central's
                         DatabaseHealthCheck<ScadaBridgeDbContext> is central-only.
                         Replication state rides along as data ENRICHMENT only:
                         replication is default-OFF, so failing on it would mark
                         every correctly-configured node unready.
  active-node   [Active] NEW SitePairActiveNodeHealthCheck, delegating to
                         IClusterNodeProvider.SelfIsPrimary. Deliberately NOT
                         central's OldestNodeActiveHealthCheck: that one calls
                         SelfIsOldest(cluster) with no role argument and would
                         compute "oldest" across the wrong member set on a mesh
                         carrying more than one site.

Anonymous, as central's are: the site pipeline runs no authentication middleware
and has no FallbackPolicy, so nothing extra was needed.

Also bumps ZB.MOM.WW.Health* 0.1.0 -> 0.2.0 (central gains data.leader for free).

Tests: SiteHealthCheckTests builds the REAL site container and activates every
registration through its factory (exact-set names, one tier tag each, resolved
types, central-only checks absent behind a positive control) plus behaviour for
both new checks. SiteHealthEndpointTests boots the real site Program over
WebApplicationFactory and proves the endpoints are MAPPED — without it, deleting
MapZbHealth would leave every registration test green while site nodes 404'd.

Joseph Doherty 86d129de6c fix(dcl): harden endpoint host-rewrite — IPv6 brackets + portless URLs
Code review of a1abbff7 found two edge cases: a discovery/advertised URL with no
explicit port emitted a malformed ':-1' (opc.tcp has no Uri default port), and an
IPv6 literal host could lose/double its brackets. Omit the port when neither URL
carries one; bracket an IPv6 host only when missing. +4 tests (12 total).

Joseph Doherty a1abbff760 fix(dcl): rewrite advertised OPC UA endpoint host to the reachable one
An OPC UA server advertises its base address from its own config, not the route
the client took — commonly a 0.0.0.0 wildcard bind or an internal container/NAT
hostname. The OPC Foundation session dials EndpointDescription.EndpointUrl
verbatim, so a 0.0.0.0 advertisement resolved to the client's own loopback and
the connect failed. RealOpcUaClient now swaps the advertised authority for the
reachable host/port (ConnectAsync + VerifyEndpointAsync), preserving scheme+path;

Joseph Doherty a5256e9b12 chore(comm): delete dead IntegrationCallRequest routing (Gitea #32)
'Pattern 4: Integration Routing' — RouteIntegrationCallAsync →
SiteEnvelope(IntegrationCallRequest) → SiteCommunicationActor integration
handler — was plumbed end to end but connected at neither end: no
producer (zero callers) and no handler (AkkaHostedService never
registered LocalHandlerType.Integration). It was an early scaffold the
architecture routed around — the brokered External→Central→Site→Central
round-trip is served by the Inbound API's routed-site-script path (the
RouteTo* verbs, driven from CommunicationServiceInstanceRouter), which is
live, tested, and shares IntegrationTimeout.

Decision (#32): delete. Removed the IntegrationCall{Request,Response}
messages, RouteIntegrationCallAsync, the SiteCommunicationActor receive
block + _integrationHandler field + LocalHandlerType.Integration, and the
four tests that covered them (2 actor, 2 message-contract, 1 dispatcher-
reject, 1 mapper-reject). KEPT IntegrationTimeout — it is the live
timeout for the RouteTo* verbs. Updated the exclusion-narrative comments
(proto/mapper/dispatcher), design §4, the components doc timeout table,
and marked the known-issue RESOLVED.

Full solution build clean (0/0); Communication 634 + Host 421 green.
Net -172/+20 across 14 files. Not in the gRPC proto (was deliberately
excluded there), so no wire-format change.

Joseph Doherty 8524a7f746 test(sms-e2e): valid Twilio SID fixture so the create path passes (Gitea #29)
TestAccountSid was 'ACtest123' (AC + 6 chars). The management create
path validates the Account SID against ^AC[0-9a-fA-F]{32}$
(ManagementActor.cs:2205, added 2026-07-10, commit 40088a21) while the
fixture predates the guard (2026-06-19) — so the create was rejected and
the config-card + secret-non-leak assertions have been red/inert since.

Use AC + 32 hex (AC00000000000000000000000000000001) so the create
succeeds and the downstream Auth-Token-non-leak assertion actually runs
again. Unit-level RepositoryCoverageTests keep their short SIDs — they
construct SmsConfiguration directly and never hit the validated path.

Joseph Doherty c4dcd9bc02 fix(transport): run bundle import inside the execution strategy (Gitea #28)
BundleImporter.ApplyAsync opened a user-initiated transaction directly,
but the central ConfigurationDb context is configured with
EnableRetryOnFailure. SqlServerRetryingExecutionStrategy rejects
user-initiated transactions, so every bundle import threw on any real
SQL Server ('...does not support user-initiated transactions.'). The
whole Transport suite ran on the in-memory provider (no retrying
strategy, BeginTransaction is a no-op) so it never surfaced.

Extract the transactional apply into ApplyMergeAsync and drive it via
_dbContext.Database.CreateExecutionStrategy().ExecuteAsync, so the
strategy owns the BeginTransaction -> apply -> Commit unit as one
retriable block. The delegate resets per-attempt state (change tracker
+ ApplyMergeAsync rebuilds its own summary/resolution accumulators) so a
retried attempt cannot double-apply; a rollback failure is captured and
surfaced on the BundleImportFailed audit row exactly as before. Post-
commit side effects (ScriptArtifactsChanged publish, session zero/
remove) moved outside the retriable delegate so they run once.

Regression test: BundleImporterRetryingStrategyTests runs the import on
SQLite with a retrying execution strategy (RetriesOnFailure == true,
arming the same guard as production). It fails with the exact production
error on the pre-fix code and passes after. Existing rollback/apply
contracts unchanged (104 integration + 154 unit tests green).

Joseph Doherty 7fd5cb2b56 feat(comm): Phase 4 — delete Akka ClusterClient site↔central transport, gRPC-only
ClusterClient→gRPC migration Phase 4 (docs/plans/2026-07-22-clusterclient-to-grpc-plan.md).
Phases 2/3 proved both directions on gRPC; this removes the Akka transport underneath.

Deleted:
- AkkaCentralTransport, AkkaSiteTransport (+ their dedicated tests)
- ISiteClientFactory + DefaultSiteClientFactory; CentralCommunicationActor legacy
  ctor + SelectTransport (Host now builds GrpcSiteTransport and injects it)
- ClusterClient creation + both ClusterClientReceptionist.RegisterService calls in
  AkkaHostedService; the RegisterCentralClient message + receive block
- CommunicationOptions.CentralContactPoints; the CentralTransport/SiteTransport
  coexistence flags; the CentralTransportMode/SiteTransportKind enums

gRPC is now the only site↔central transport (site→central CentralControlService via
GrpcCentralTransport; central→site SiteCommandService via GrpcSiteTransport), both
built unconditionally by the Host. NoOpCentralTransport is the fail-loud null-default
so TestKit command-dispatch suites still construct the site actor without a wired
transport; production always injects GrpcCentralTransport.

Config: CentralGrpcEndpoints is now unconditional — CommunicationOptionsValidator
rejects blank entries (role-agnostic), and StartupValidator requires a Site node to
list >=1 endpoint (fail-fast, mirrors GrpcPsk). Rig configs moved
CentralContactPoints -> CentralGrpcEndpoints (docker x6, docker-env2 x2, Host default,
deploy/wonder-app-vd03). Kept Akka.Cluster.Tools (ClusterSingleton still used).

Tests: build 0/0; Communication.Tests 640, Host.Tests 421 green. Removed the
ClusterClient.Send per-site-routing tests (covered by the transport suites), swapped
the ISiteClientFactory-based ctors to a substitute ISiteCommandTransport, converted
the audit-push integration relay to an in-process bridge transport.

Docs: Component-Communication/Host/StoreAndForward, components/Communication,
topology-guide, grpc_streams (SUPERSEDED note), the frame-size known-issue (retired
amendment), and CLAUDE.md transport decisions.

Not included: the dead IntegrationCallRequest path (#32) is a separate user-owned
behavioral decision — SiteEnvelope routing is transport-agnostic so it still compiles.

Joseph Doherty 86ad4d5c8e feat(comm): T1B.3 — central-side gRPC site-command transport seam (default Akka)
Extract the central→site send path in CentralCommunicationActor behind a new
ISiteCommandTransport, selected by ScadaBridge:Communication:SiteTransport
(Akka | Grpc, default Akka — rollback = flip the flag). CommunicationService's
27 commands, SiteCallAuditActor's 2 parked relays and DebugStreamBridgeActor's
subscribe/unsubscribe are untouched; the seam sits below SiteEnvelope.

- AkkaSiteTransport: today's per-site ClusterClient path extracted verbatim
  (the _siteClients lookup + ClusterClient.Send with the reply-to sender
  preserved, and the "no client ⇒ warn + drop, caller's Ask times out" path).
- GrpcSiteTransport: dials the site SiteCommandService (T1B.1 proto client) via
  SiteCommandDtoMapper, PSK + x-scadabridge-site on the channel through
  ControlPlaneCredentials, per-command deadlines set EQUAL to today's
  CommunicationService Ask timeouts (per-command, not per-group: DeploymentState
  query and TriggerSiteFailover use QueryTimeout; the two parked relays map to
  QueryTimeout so SiteCallAudit's inner RelayTimeout 10s < 30s ordering holds;
  WaitForAttribute keeps its dynamic Timeout + IntegrationTimeout).
- SitePairChannelProvider: per-site A/B channel pair with sticky failover
  (flip only on Unavailable — NEVER on DeadlineExceeded, a write/deploy/failover
  may have run), background failback probe to the preferred node with 1s→60s
  doubling backoff, PSK invalidation on site removal. Fed by the SAME DB refresh
  loop (extended to carry GrpcNodeA/GrpcNodeBAddress) — no second poll.

Tests: actor-with-substitute-transport (routing, Ask-reply plumbing, per-site
lifecycle across refreshes), ResolveDeadline pinned to each command's current
Ask timeout, and GrpcSiteTransport/SitePairChannelProvider over dual in-process
TestServers (PSK+header+deadline attached, Unavailable failover + stickiness,
failback to preferred, no-retry-on-DeadlineExceeded). Proto csproj untouched
(no active <Protobuf> item). Full solution builds 0 warnings; Communication.Tests
607 green with Akka default.

Joseph Doherty 518c699b90 feat(comm): extract SiteCommandDispatcher; site serves commands over gRPC too (T1B.2)
Refactor SiteCommunicationActor's central→site routing table into one
SiteCommandDispatcher — the single routing truth for the 28 migrated commands
(IntegrationCallRequest, the dead 29th, stays on the actor and out of the
dispatcher). The Akka actor and the new SiteCommandGrpcService both route through
one dispatcher instance so the two transports can never drift on where a command
goes. Server-side only: nothing central flips to gRPC yet (that is T1B.3);
ClusterClient remains the live path.

Decisions worth recording:

- Targets preserved byte-for-byte. Lifecycle/OPC UA/query/route → the Deployment
  Manager singleton proxy; DeployArtifacts/EventLog/parked → their null-guarded
  handlers with the exact same "handler not available" replies; the parked
  handler stays NODE-LOCAL (per-node replicated-store owner), never the singleton
  proxy — pinned by a dispatcher test that asserts the target is the parked probe
  and NOT the dm proxy.

- Sender preservation intact. The actor's command handlers became thin
  DispatchCommand delegations that still Forward (central Ask → reply routes
  straight back); the existing SiteCommunicationActorTests pass unchanged, which
  is the regression guard for that plumbing. UnsubscribeDebugView keeps its
  fire-and-forget shape: the actor Forwards, the gRPC service Tells + returns the
  synthetic UnsubscribeDebugViewAck so a unary RPC still answers.

- Ack-before-Leave on failover. The dispatcher's PrepareFailover resolves the
  standby with a DRY-RUN (no leave) to build the ack, and hands back a deferred
  CommitLeave; the gRPC service returns the ack, then schedules the real
  Cluster.Leave — so a caller reaching the very node about to leave still gets its
  ack instead of a broken stream. The actor path keeps today's coupled
  resolve-and-leave (over ClusterClient the ack Tell only enqueues, so order is
  immaterial). Proven at both levels: a dispatcher test asserts the ack is built
  before CommitLeave runs, and a TestServer test asserts the recorded seam order
  is resolve-then-leave.

- ControlPlaneAuthInterceptor gates SiteCommandService by EXTENDING
  DefaultGatedPrefixes (descriptor-derived), not by adding a constructor — the
  one-public-ctor invariant and its test stay green.

Tests: SiteCommandDispatcherTests (28-command routing incl. parked node-locality
and both failover paths) and SiteCommandGrpcService TestServer tests (auth,
readiness→Unavailable, one command per oneof group, failover ordering). Full
solution build 0/0; Communication.Tests 574 and Host.Tests 377 green. No active
<Protobuf> item.

Joseph Doherty 59b13d317b feat(grpc): T1B.1 — site_command.proto + SiteCommandDtoMapper + round-trip goldens
Phase 1B's contract slice: the wire shape and the canonical translation for the
28 central→site commands that leave ClusterClient. No behaviour changes yet —
SiteCommunicationActor and CentralCommunicationActor are untouched; the
dispatcher refactor (T1B.2) and the central transport seam (T1B.3) consume this.

Protos/site_command.proto (package scadabridge.sitecommand.v1, service
SiteCommandService): six domain RPCs, each with a `oneof` request/reply
envelope. The grouping is what carries deadline policy — every command inside a
group shares a CommunicationOptions timeout class today, so one RPC per group
keeps the deadline choice in one place on the client and one dispatch switch on
the server, while the oneof keeps each command individually typed:
ExecuteLifecycle(6) · ExecuteOpcUa(8) · ExecuteQuery(4) · ExecuteParked(5) ·
ExecuteRoute(4) · TriggerFailover(1). IntegrationCallRequest — the 29th entry on
SiteCommunicationActor's receive table — is deliberately excluded as dead code
(2026-07-22-integration-call-routing-is-dead-code.md).

Contract decisions worth knowing:

- Nullable COLLECTIONS ride in per-collection wrapper messages
  (DeployArtifactsCommand's six artifact lists, CertTrustResult.Certs,
  RouteToCallRequest.Parameters). proto3 repeated/map collapses null into empty,
  and that distinction is live at the site — the same silent-data-loss class the
  transport round-trip guard exposed in PLAN-05 T8. Goldens cover null, empty
  and populated for each.
- Nullable strings use the empty-string-means-null convention already set by
  AuditEventDtoMapper, with ONE exception: RouteToWaitForAttributeRequest's
  TargetValueEncoded, where "wait for the empty string" is a real target, so it
  carries a StringValue wrapper. Both behaviours are asserted, not assumed.
- Nullable enums ride in one-field messages (proto3 enums have no presence and
  no stock wrapper). Enum translation is an explicit switch in both directions —
  never by ordinal — so reordering a C# enum cannot re-map the wire; every wire
  enum reserves 0 for _UNSPECIFIED and decodes to a documented safe default
  rather than faulting a command from a version-skewed peer.
- New LooseValueCodec carries the surviving `object?` members (script params and
  return values, attribute values, tag read/write values) as a type-tagged union
  so a boxed value keeps its runtime CLR type, as it does today under Akka's
  type-preserving JSON serializer. Dates ride as invariant round-trip strings,
  not Timestamp, which would silently normalise away DateTime.Kind and
  DateTimeOffset.Offset. Lists/maps recurse; anything outside the tagged set
  falls back to JSON and is documented as CLR-type-lossy.
- DebugViewSnapshot gets its own full-fidelity alarm/attribute messages rather
  than reusing sitestream's AlarmStateUpdate, which flattens values to display
  strings — right for a live stream, lossy for a snapshot the UI treats as
  authoritative. The encoder omits an AlarmStateChanged.Condition that already
  equals the record's derived default, so computed alarms round-trip exactly
  (record equality compares the nullable backing field, not the property).

Tests are reflection-driven so the coverage cannot drift: the round-trip theory
enumerates the mapper's own ToProto overloads, the envelope guards enumerate the
generated oneof descriptors, and a missing golden fails the build. 216 new tests
green (Communication 532 total, Commons 684 total, solution build 0/0).

Codegen is checked in under SiteCommandGrpc/ per the sitestream recipe; the
<Protobuf> ItemGroup stays commented out (an active one segfaults protoc in the
linux_arm64 Docker image). docker/regen-proto.sh now handles every proto in that
ItemGroup instead of just sitestream, and re-comments idempotently.

Joseph Doherty 0e162cb250 fix(grpc): central Kestrel gRPC listener was dropping the :5000 HTTP surface (T1A.2 regression)
Caught on the Phase 1A rig proof: central-a logged only "Now listening on:
http://[::]:8083" and nothing else. Central UI, the Management + Inbound API, and
the /health/* endpoints Traefik + IActiveNodeGate depend on were all gone, with no
startup error — the node booted, joined the cluster and served gRPC fine.

Cause: calling options.ListenAnyIP in ConfigureKestrel puts Kestrel into
explicit-endpoints mode, which SUPPRESSES the URLs from ASPNETCORE_URLS/--urls
entirely — it is not additive, contrary to the comment T1A.2 shipped. Central's whole
HTTP/1 surface lives on that URL (http://+:5000 on the rig, a different port in prod),
so binding only the gRPC port silently deleted it. The site branch has the same shape
but no ASPNETCORE_URLS surface to lose — it binds every port it needs explicitly.

Fix: parse the port(s) from the configured URLs and re-declare them (Http1AndHttp2)
alongside the gRPC port (Http2) in the one ConfigureKestrel call. New
Program.ParseHttpBindPorts + CentralHttpBindPortsTests (14 cases: wildcard/ipv6/
hostname hosts, multi-URL, de-dupe, scheme-default, null/blank, unparseable-skipped).

Why no test caught it originally: unit/E2E tests use TestServer, which never binds
real Kestrel. Only a live node exposes the missing listener — which is exactly what
the rig proof is for.

Joseph Doherty 33b15f10a4 feat(grpc): site-side ICentralTransport seam + gRPC transport (T1A.3)
Introduce ICentralTransport as the site->central choke point inside
SiteCommunicationActor. The seven site->central sends (notification submit/
status, audit + cached-telemetry ingest, reconcile, health, heartbeat) now
delegate to an injected transport instead of owning ClusterClient.Send inline.

- AkkaCentralTransport: verbatim extraction of today's ClusterClient.Send path,
  including the exact sender-forwarding that routes central's reply straight
  back to the waiting Ask. Default when no transport is injected -> behaviour
  unchanged, existing SiteCommunicationActorTests pass as-is.
- GrpcCentralTransport + CentralChannelProvider: dial CentralControlService with
  sticky failover + background failback (1s-doubling-cap-60s), PSK +
  x-scadabridge-site via ControlPlaneCredentials, per-call deadlines mirroring
  today's Ask timeouts. Cross-node retry ONLY on provably-unsent
  connect failures; never on DeadlineExceeded. Heartbeat stays fire-and-forget.
- StaticSitePskProvider: site's single own-key provider (fail-closed).
- CommunicationOptions: CentralTransport flag (default Akka) + CentralGrpcEndpoints
  (validator: required when transport=Grpc). Host selects the impl; the
  ClusterClient is created only on the Akka path.

Tests: actor-with-fake-transport (7 delegations + fault routing + heartbeat
no-fault), AkkaCentralTransport sender-forwarding, GrpcCentralTransport over
in-process TestServer (failover flip, sticky, failback, PSK+header, deadline,
no-retry-on-deadline), validator. Communication.Tests 371 green, Host.Tests 391
green; the three above-seam suites pass unmodified.

Joseph Doherty 780bb9c369 feat(grpc): host CentralControlService on the central node (T1A.2)
Central now ALSO listens for the seven site→central control messages over
gRPC, alongside the existing ClusterClient path. Nothing flips to gRPC yet —
sites keep CentralTransport=Akka (T1A.3's job); central simply starts also
accepting.

- CentralControlGrpcService (Communication.Grpc): decodes each RPC onto the
  SAME in-process message the ClusterClient path carries, Asks the existing
  CentralCommunicationActor (zero handler-logic changes), encodes the reply via
  the T1A.1 mapper. Readiness-gated like SiteStreamGrpcServer.SetReady —
  Unavailable until AkkaHostedService hands the actor over. Heartbeat stays
  fire-and-forget (Tell, always-OK, never gated on readiness). Ingest reuses the
  shared SiteStreamGrpcServer.AuditIngestAskTimeout constant. Fault→status
  mapping is retry-aware: Unavailable (never dispatched, safe to cross-node
  retry) vs DeadlineExceeded/Internal (it ran, do not re-send elsewhere).

- CentralControlAuthInterceptor (Host): a SEPARATE interceptor class, not a
  variant constructor on ControlPlaneAuthInterceptor. Central's model is per-site
  (verify the Bearer token against the key for the site in the required
  x-scadabridge-site header, via ISitePskProvider) where a site verifies its one
  own-key — a genuinely different model. Fail-closed on every branch: missing or
  blank header, unresolvable key, and mismatched token all → PermissionDenied,
  never pass-through. One public constructor only (the explicit-prefix ctor is
  internal), pinned by a reflection test — a second public ctor makes
  Grpc.AspNetCore's GetFactory() throw per-call and silently disables the gate.

- Explicit Kestrel h2c listener on new option ScadaBridge:Node:CentralGrpcPort
  (default 8083, symmetric with sites), mirroring the Site branch. Additive to
  central's :5000 HTTP/1 surface, which is untouched — gRPC does NOT go through
  Traefik (HTTP/1 only). Registered by type on AddGrpc; service mapped with
  MapGrpcService. Port range-validated by NodeOptionsValidator.

- Rig: publish the central gRPC port 9013:8083 / 9014:8083 on both central nodes
  so a later task can exercise it.

Tests: CentralControlEndToEndTests (Host.Tests, TestServer + real interceptor +
real service over a stub actor) proves auth positives/negatives are
distinguishable and covers unary + the ingest bridge shapes; the interceptor is
registered BY TYPE, never in DI. CentralControlAuthInterceptorTests pins the
per-site gate + one-public-ctor invariant. CentralControlGrpcServiceTests
(Communication.Tests, TestKit) covers the readiness gate, fire-and-forget
heartbeat, and the DeadlineExceeded-vs-Unavailable status mapping. No active
<Protobuf> item. Communication.Tests (356) + Host.Tests (384) green.
2026-07-22 18:53:59 -04:00
Joseph Doherty d7455577a8 feat(grpc): central_control.proto + DTO mapper for the 7 site→central control RPCs (T1A.1)
Phase 1A of the ClusterClient→gRPC migration needs a wire contract for the
seven messages SiteCommunicationActor forwards to /user/central-communication.
This lands the contract and its mapper only — hosting (T1A.2) and the site-side
transport seam (T1A.3) follow.

`Protos/central_control.proto` (package scadabridge.centralcontrol.v1, service
CentralControlService) declares SubmitNotification, QueryNotificationStatus,
IngestAuditEvents, IngestCachedTelemetry, ReconcileSite, ReportSiteHealth and
Heartbeat. Note the direction is the inverse of SiteStreamService: here the site
dials and central serves.

Decisions worth recording:

- The two ingest RPCs IMPORT sitestream.proto and reuse AuditEventBatch /
  CachedTelemetryBatch / IngestAck rather than redeclaring them. The site
  telemetry actor already builds those messages, so a second copy would fork one
  wire contract into two kept in lockstep by hand. ForwardState / IngestedAtUtc
  stay off-wire exactly as they are today.
- Heartbeat replies google.protobuf.Empty — it is fire-and-forget and must never
  surface a fault onto the heartbeat timer path.
- The three NULLABLE SiteHealthReport collections travel inside single-field
  wrapper messages (ConnectionEndpointMapDto / TagQualityMapDto /
  NodeStatusListDto). proto3 cannot express presence on repeated/map fields, but
  null and empty genuinely differ here — SiteHealthCollector emits
  `ClusterNodes: _clusterNodes?.ToList()` and the central health surface reads
  null as "not reported", not as "reported empty". Same reasoning drives the
  BoolValue/Int64Value/DoubleValue wrappers on LocalDbReplicationConnected,
  LocalDbOplogBacklog and the two age gauges, whose docs are explicit that null
  is not zero/false.
- ConnectionHealthEnum reserves 0 for UNSPECIFIED instead of mapping Connected
  onto it, and the decoder resolves anything unknown to ConnectionHealth.Error.
  An unrecognised connection state must not render as "healthy".
- Guid? execution ids travel as "D" strings with empty meaning null; a malformed
  non-empty value throws rather than being laundered into "no correlation".
- DateTimeOffset normalizes to a UTC instant (a protobuf Timestamp has no
  offset). Lossless in practice — every producer stamps UTC — and documented +
  asserted rather than left implicit.

SiteCallDtoMapper gains a ToDto(SiteCall) overload. Its doc comment previously
asserted such a method "would be dead code"; that held only while ClusterClient
was the sole path from IngestCachedTelemetryCommand (which carries SiteCall, not
SiteCallOperational) to central. Comment corrected alongside.

Golden tests round-trip every message through a real protobuf encode/decode —
DTO → proto → bytes → proto → DTO — with a fully-populated case and a
null/empty/minimal case for every optional member. Verified to have teeth by
mutation: dropping a scalar, collapsing an empty nullable collection to absent,
and nulling a gauge each fail a test.

Codegen stays CHECKED IN under CentralControlGrpc/ (protoc segfaults in the
linux_arm64 Docker image); no active <Protobuf> item is committed.
docker/regen-proto.sh is generalized to `regen-proto.sh [sitestream|
centralcontrol|all]` — it now injects the ItemGroup rather than unwrapping a
comment, so it no longer depends on there being exactly one Protobuf line, and
it restores the csproj verbatim on every exit path.
2026-07-22 18:28:27 -04:00
Joseph Doherty 228ff8b428 fix(grpc): one public constructor on ControlPlaneAuthInterceptor — two made the gate inert
Caught by the Phase 0 live gate, not by the suite.

Grpc.AspNetCore registers the interceptor BY TYPE, and
InterceptorRegistration.GetFactory() throws "Multiple constructors accepting all
given argument types have been found" when more than one public constructor is
applicable. The interceptor had two: the DI one and a prefix-set overload added
for later phases.

The failure mode is nasty. The throw happens inside the interceptor pipeline on
every call, so nothing fails at startup — the site node boots, joins, reports
healthy. Every gated call then dies with Unknown / "Exception was thrown by
handler", which reads as a handler bug rather than an auth bug. And it fails
OPEN in the sense that matters least and closed in the sense that matters most:
no call is ever authorized, but no call is ever correctly REFUSED either, so the
rig showed identical errors for a correct key, a wrong key and no key at all.
Live evidence, site-a: three PullAuditEvents calls, three identical
InvalidOperationExceptions in the node log.

Fix: the prefix-set constructor is internal (Host.Tests already has
InternalsVisibleTo). Later phases extend DefaultGatedPrefixes rather than adding
a second public registration shape.

Why the tests missed it, and what changed: ControlPlaneAuthEndToEndTests
registered the interceptor with AddSingleton alongside AddGrpc, so DI handed
back the instance and Grpc.AspNetCore's activation path — the thing that throws
— never ran. The harness now registers exactly as Program.cs does, by type and
not in DI. Plus a direct reflection assertion that the type has exactly one
public constructor, since that is the real invariant and it is cheap to pin.
2026-07-22 17:56:51 -04:00
Joseph Doherty 2ee84af1c0 feat(grpc): PSK-authenticate the site gRPC control plane; drop the vestigial management receptionist registration
Phase 0 of the ClusterClient→gRPC migration
(docs/plans/2026-07-22-clusterclient-to-grpc-plan.md). Standalone hardening: it
closes a gap that exists today and is a precondition for moving command/control
onto gRPC in later phases.

T0.1 — delete the ManagementActor ClusterClientReceptionist registration.
It was built for an out-of-cluster CLI that was never written: the shipped CLI
speaks HTTP Basic to /management, which asks the actor in-process through
ManagementActorHolder. Nothing in the repo ever sent to /user/management. The
actor still runs there; only the cross-boundary advertisement is gone. Six
documents claimed the CLI used ClusterClient — including the CLI's own README
"Architecture Notes" — and are corrected here rather than left to rot.

T0.2 — record, do not port, the dead integration-routing path.
IntegrationCallRequest is unwired at BOTH ends: RouteIntegrationCallAsync has
zero callers anywhere, and RegisterLocalHandler(Integration, …) appears only in
a test, so production always answers "Integration handler not available". It is
excluded from the gRPC contract (28 of 29 commands migrate) rather than
enshrined on an additive-only wire format, and deleting it during a
transport migration would mix a behavioural change into a change whose whole
value is that behaviour is identical. See
docs/known-issues/2026-07-22-integration-call-routing-is-dead-code.md.

T0.3 — preshared-key authentication on SiteStreamService.
The service shipped with no auth at all: plaintext h2c, no interceptor, so
anything that could reach a site node's :8083 could open a live data stream or
read audit rows back via PullAuditEvents/PullSiteCalls. ControlPlaneAuthInterceptor
now gates /sitestream.SiteStreamService/ — modeled on LocalDbSyncAuthInterceptor
(constant-time compare, fail-closed, PermissionDenied) but gating a SET of
service prefixes so phases 1A/1B add services rather than interceptors. LocalDb
sync keeps its own separate key: it authenticates the pair partner, not central,
and collapsing the two would make a site's central-facing key also admit writes
into its database.

Keys are per site (SB-GRPC-PSK-<siteId>), never fleet-wide, so a compromised
site yields only its own. Central attaches them through ControlPlaneCredentials,
which binds CallCredentials to the channel — covering unary and streaming
uniformly, and letting the key resolve asynchronously, which a client
interceptor could not do without blocking. All three central→site channel
creation sites go through it (SiteStreamGrpcClient and both audit pull invokers);
the pull invokers' channel caches are re-keyed by (site, endpoint) because
credentials are per-site and bound to the channel.

Two decisions beyond the plan:

  * StartupValidator now requires GrpcPsk on Site nodes. The plan specified only
    the runtime gate, but fail-closed with no boot check produces a node that
    joins, answers heartbeats and reports healthy while refusing every stream,
    audit pull and telemetry ingest — silent and total. Same reasoning as the
    existing inbound API-key pepper rule.

  * Added Communication:SitePsks as a central-side key map. The plan assumed
    central would read the store, seeded via a dev KEK; the docker rig
    deliberately boots with no master key, so store-only resolution would leave
    it unable to dial its own sites. The store stays primary — it is the only
    source that can serve a site added at runtime — with the map covering
    key-less hosts and one-off pins. Neither source falling back to
    "unauthenticated" is the invariant.

T0.4 — dev keys on both rigs and tests.
34 tests. The seven that matter most exercise a real in-process gRPC stack over
TestServer: the unit tests on either side of the wire would both stay green if
the halves disagreed, and gRPC refuses call credentials on a plaintext channel
by default — the UnsafeUseInsecureChannelCallCredentials opt-in is only provable
by making a real call. They confirm correct key passes on unary AND streaming,
wrong key and no-credentials both get PermissionDenied, and an unresolvable key
fails the call with nothing reaching the service.

OPERATIONAL: a site node upgraded to this build without a key will not boot.
That includes the gitignored deploy/wonder-app-vd03/ overlay.

Joseph Doherty c8e2f4da02 feat(cluster): site-pair manual failover relayed from the central UI (Task 10)
Central and each site are SEPARATE Akka clusters, so central cannot act on a
site's membership -- it asks. New TriggerSiteFailover/SiteFailoverAck contract
travels the existing ClusterClient command/control channel (mirroring the
RetryParkedOperation relay); the site's own SiteCommunicationActor performs the
graceful Leave and acks the outcome.

- ClusterFailoverCoordinator moved out of Host into Communication/ClusterState,
  beside ActiveNodeEvaluator. Both paths now share ONE oldest-Up implementation;
  SiteCommunicationActor cannot reference Host, and the two definitions must not
  drift or the node asked to leave stops being the singleton host.
- Site scope is the SITE-SPECIFIC role (site-{SiteId}), not the base Site role --
  site singletons are placed on the former, so the base role would move the wrong
  node. Pinned by a unit test asserting the role string and by a real-cluster test.
- Site-side guards: refuses a command addressed to another site (a misroute must
  never fail over a site the operator did not select), refuses when there is no
  peer, and reports a fault as an ack rather than throwing into supervision --
  a restart there would drop central's Ask into a bare timeout and lose the reason.
- Ack is sent before the Leave takes effect so it still reaches central.
- UI: the same control now serves both scopes via a SiteId parameter. The site
  confirmation deliberately does NOT claim the admin's page will disconnect --
  it won't, and crying wolf there devalues the central warning that is real. A
  site refusal and an unreachable site surface distinctly.
- Rolling upgrade: a site on an older binary has no handler, so the message
  dead-letters and the Ask times out, reported as "site did not respond". That
  is the honest outcome; documented on the contract.

Fallout fixed: HealthPageTests now renders the page inside
CascadingAuthenticationState with the real policy set and IAuthorizationService,
because the cards embed an AuthorizeView. That mirrors production, where the
layout supplies the cascading value.

Joseph Doherty caf14a3e03 feat(ui): admin manual-failover control on the health page
CentralFailoverControl lives in Components/Health/ (matching AuditKpiTiles /
SiteCallKpiTiles) rather than inline in Health.razor, so it is testable without
standing up the whole dashboard's DI graph.

- Admin-gated via AuthorizeView + RequireAdmin. The Health page itself is
  intentionally all-roles, so the gate belongs on the control, not the page.
- Disabled with an explanatory title when the pair has no online standby;
  the authoritative guard remains server-side against live cluster membership.
- Confirmation dialog (IDialogService, the page idiom) warns that singletons
  hand over, in-flight work on the active node is interrupted, and THIS PAGE
  will disconnect and reconnect against the new active node -- Traefik routes
  the UI to the node being restarted, so a working failover otherwise reads as
  a crash the admin caused.
- A refused failover (service returns null) surfaces the refusal; the UI never
  reports a failover that did not happen.

7 bUnit tests. Two harness requirements that bit first: AuthorizeView needs a
cascading AuthenticationState (the app supplies it from the layout), and
BunitContext pre-registers a placeholder IAuthorizationService that throws on
policy evaluation -- both handled the same way NavMenuTests documents.

Runbook paragraphs added to Component-ClusterInfrastructure.md (new Manual
Failover section) and docker/README.md.

Joseph Doherty f679d5c749 feat(cluster): manual central failover service — graceful Leave of the oldest Up member
Admin-triggered failover of the central pair. IManualFailoverService is declared in
CentralUI (plain strings, so that project stays Akka-free); AkkaManualFailoverService
implements it in the Host and is registered only in the Central branch.

- Leave, never Down: singletons hand over instead of being killed.
- Target = oldest Up member with the Central role, mirroring ActiveNodeEvaluator, so
  the node acted on is exactly the one hosting the singletons (never the leader,
  whose address-ordered definition diverges from singleton placement after a restart).
- Peer guard: returns null when fewer than 2 Up Central members — failing over a lone
  node is an outage, not a failover.
- Audited BEFORE the Leave is issued via ICentralAuditWriter: the acting node can be
  the one that goes away, and an audit written after could be lost to the shutdown it
  describes. Best-effort — audit failure never blocks the failover.

New audit taxonomy: AuditChannel.Cluster + AuditKind.ManualFailover (operator-initiated
topology actions are not script trust-boundary crossings, but are exactly what an audit
log exists to attribute). Lock-in tests updated 5->6 channels, 16->17 kinds.

alog.md §4 updated per the lock-in tests' contract. Both tables were already stale --
the Channel row omitted SecuredWrite and the Kind table claimed 10 while the code had
16 -- so they are completed here, not merely appended to.

ManualFailoverTests: 3 real-cluster tests (oldest leaves + survivor takes over, peer
guard refuses with a positive still-running assert, dry-run probe does not perturb).
2026-07-22 06:55:15 -04:00
Joseph Doherty 4a6341d871 feat(cluster): self-first seed ordering closes the boot-alone outage gap
Every node now lists ITSELF as seed-nodes[0] and its partner second. Akka runs
FirstSeedNodeProcess -- the only bootstrap path that can form a NEW cluster when
no peer answers InitJoin -- exclusively for seed-nodes[0]; every other node runs
JoinSeedNodeProcess and retries InitJoin forever. That is why a lone cold-starting
central-b never came Up (the "registered outage gap"), and self-first ordering
closes it using Akka's own protocol.

- 6 node appsettings swapped (the *-node-b configs; the -a nodes were already
  self-first). All 14 shipped node configs now satisfy the invariant.
- StartupValidator enforces it at boot, comparing host AND port -- the invariant
  fails silently when broken, so it is enforced loudly. NOTE: the gitignored
  deploy/wonder-app-vd03/ overlay must be reordered before its next deploy or
  that node will refuse to boot.
- SelfFirstSeedBootstrapTests: real in-process clusters at production
  failure-detection timings, incl. a falsifiability control proving the OLD
  peer-first ordering never forms.

Rejected alternative (implemented, measured, discarded): an external self-form
timer calling Cluster.Join(SelfAddress) after a window. It sits outside Akka's
join handshake and so cannot tell "no seed answered" from "a seed answered and
the join is in flight". On a routine standby restart the peer is alive but the
join stalls behind removal of the node's own stale incarnation; a Join(self)
during TryingToJoin abandons the in-flight join and forms a second cluster at
the same address -- still split after 90s. Docs that claimed self-first ordering
was unsafe for simultaneous cold start are corrected: while mutually reachable
the InitJoin handshake converges them to one cluster (measured).

Joseph Doherty cf3bd52f93 feat(cluster): auto-down downing strategy — either-node crash now fails over (owner decision 2026-07-21: availability over partition-safety)
Two-node keep-oldest could NEVER survive a crash of the oldest/active node:
Akka.NET 1.5.62 KeepOldest.OldestDecision only lets down-if-alone rescue a
side with >= 2 members, so the 1-vs-1 survivor takes DownReachable and downs
ITSELF — proven live on the rig ('SBR took decision ... including myself')
before this change. static-quorum(1) is worse (IsTooManyMembers -> DownAll);
keep-majority just re-keys the fatal crash to the lowest address.

SplitBrainResolverStrategy gains 'auto-down' (new default): BuildHocon emits
Akka's AutoDowning provider with auto-down-unreachable-after = StableAfter.
The leader among the REACHABLE members downs the unreachable peer, so the
survivor takes over singletons and /health/active in ~25s regardless of which
node died. Accepted trade (explicit owner decision): a real network partition
runs dual-active until an operator restarts one side. keep-oldest remains
supported; DownIfAlone validation is now scoped to it.

Live drill on the rebuilt rig: active-crash TAKEOVER in 28s (victim still
down; all 7 singletons Younger->Oldest), standby-crash removal 27s with 0
routing blips; victims rejoin as standby in 2s. New real-cluster tests pin
both directions (SbrFailoverTests.AutoDown_*); TwoNodeClusterFixture gains a
strategy knob. All 16 appsettings flipped (src, docker, docker-env2, and the
gitignored wonder-app-vd03 overlay on disk — owner must sync to the host).
Docs: decision record docs/plans/2026-07-21-auto-down-availability-decision.md,
Component-ClusterInfrastructure downing section rewritten, drill + README
reworked (active mode now asserts takeover), deferred-work SBR row resolved.

Joseph Doherty 62cddcfa56 fix(audit): let an unresolvable cached row leave the drain queue
A cached-telemetry audit row whose OperationTracking snapshot could not be
resolved was skipped and left Pending. Nothing ever removed it, so the next
drain re-read it, failed identically, and logged again — forever.

The severity was worse than the original write-up said. The queue is read
oldest-first with a fixed BatchSize (default 256), so once a batch's worth of
permanently-unresolvable rows collected at the head, every drain re-read
exactly those rows and NEVER REACHED the newer rows behind them. That is a
permanent stall of the cached-telemetry path, not the "log flood, no data loss"
the issue was first filed as. Measured on the rig at ~2,800 warnings/minute,
surviving both a process restart and a container restart.

Fix: after a grace period (CachedTrackingGraceSeconds, default 300 s) the
operational half is abandoned and the row marked Forwarded. A row with no
CorrelationId is abandoned immediately — it can never resolve.

Marking Forwarded does not drop audit data. That state means "no longer owed by
the drain, still eligible for reconciliation", which is exactly this situation:
ReadPendingSinceAsync covers Forwarded as well as Pending and central dedups on
EventId, so the reconciliation pull still delivers the audit half. What is lost
is the operational (SiteCalls) half, which is unrecoverable anyway once the
tracking row is gone.

Three deliberate boundaries:
- Inside the grace window the row is still retried — a missing snapshot is
  normally a brief write race, and abandoning on the first failed lookup would
  discard the operational half of every cached call that lost that race.
- A tracking-store THROW never abandons, however old the row: a throw is a
  store fault (locked, corrupt, mid-restore), not a verdict about the row.
- Logging is per drain pass, not per row. Deferred rows dropped to Debug —
  being inside the grace window is normal operation, not a warning.

CachedDrain_OrphanRow_NoTrackingSnapshot_IsSkipped_DoesNotCrash was RETARGETED
rather than deleted: it pinned the defect ("skipped and stays Pending"), so its
orphan assertion is inverted and the half that still holds is kept verbatim.
Three tests added, including the starvation regression. Both "must NOT abandon"
tests carry a positive control on the read count, so they cannot pass by virtue
of a drain that never ran.

Verified non-vacuous: with abandonment disabled the two abandonment tests go
red and the two guards stay green. Build 0 warnings; AuditLog 358, Host 330,
SiteRuntime 512, StoreAndForward 130, Communication 312, Commons 684,
Integration 94 — all pass.

Joseph Doherty 166f07fa68 chore(localdb): adopt LocalDb 0.1.1 and drop the directory shim
LocalDb 0.1.1 creates the parent directory of LocalDb:Path itself, so the
SiteLocalDbDirectory shim this repo carried through Phase 2 is deleted along
with its call site. The gap was found here but was never ScadaBridge's alone —
every LocalDb consumer had it — so the fix moved to the library.

SiteLocalDbDirectoryTests is RETAINED and retargeted rather than deleted with
the shim. It was already written against the site registration path, not the
mechanism, so it needed only its Ensure() call removed: what a site node
requires is that resolving ILocalDb not fail on a fresh machine, regardless of
who provides that. Verified it still earns its place — pinned back to LocalDb
0.1.0 it fails inside SqliteLocalDb..ctor -> SqliteConnection.Open(), so it
genuinely depends on the library behaviour and not on a coincidence.

Also corrects the coverage-split note in StoreAndForwardStorageTests, which
asserted that directory creation is "NOT LocalDb's" — true when written, wrong
as of 0.1.1.

Build 0 warnings; Host 330, StoreAndForward 130, LocalDb integration 20 pass.

Joseph Doherty 15013156bf test(localdb): two-node convergence for config tables + sf_messages
Four scenarios over the real site pair, driven through the REAL
SiteStorageService rather than hand-written SQL. The sibling suites had to
hand-write SQL because they were specifications written BEFORE the cutover;
this suite runs after it, so it can drive the shipped writers — which is what
makes the cascade scenario meaningful.

- DeployedConfigRow_ConvergesToB_ColumnForColumn: the existing suite asserts
  config_json only, so a capture that dropped or defaulted any other column
  would still pass. deployed_at matters most — SiteReconciliationActor's
  guarded write compares it.
- RemovingAnInstance_ConvergesAllThreeCascadeTables: the plan's flagged
  highest-risk case. RemoveDeployedConfigAsync deletes from three tables in one
  transaction, the schema has no foreign keys, and CDC ships three independent
  per-table streams. A dropped delete leaves a permanently stale override or
  alarm row on the standby, invisible until the instance name is redeployed.
  Carries a never-removed control instance, without which "the cascade
  converged" is indistinguishable from "node B lost these tables entirely".
- ANativeAlarmBurst_Converges_AndTheOplogDrains: convergence alone would pass
  if entries replicated but were never acked, and an oplog that only grows
  trips the caps into a snapshot resync.
- RowsWrittenOnBWhileItsListenerIsDown_SurviveTheRejoin: the union-survives
  property is per-table, and an unregistered table is silently local-only
  rather than an error, so it is re-proved on the tables the N1 scenario does
  not touch.

Non-vacuity verified as the plan requires: with the eight Phase 2
RegisterReplicated calls commented out in SiteLocalDbSetup, all four go red
(4 failed / 0 passed); restored, 20/20 pass across the three LocalDb suites.

Joseph Doherty 605e56829e chore(config): retire ReplicationEnabled, make legacy db paths migration-only
LocalDb Phase 2 deleted the bespoke replicators, so three config keys changed
meaning or died outright:

- ScadaBridge:StoreAndForward:ReplicationEnabled is fully dead. Deleted the
  property, its 10 config entries, and the 5 test references.
- SqliteDbPath / SiteDbPath are now migration-only: they name the legacy files
  SiteLocalDbLegacyMigrator drains at boot, not live databases. Both mandatory
  rules are relaxed accordingly (StartupValidator's Site-only Require, and the
  S&F validator's non-empty rule) — an absent value now means "nothing to
  migrate", so an already-migrated node can drop the key. DatabaseOptions-
  Validator still rejects a present-but-blank value.
- SiteRuntime:ConfigFetchRetryCount's only reader was SiteReplicationActor.
  Deleted with its validator rule.

The two path keys stay present in every config, now with a comment explaining
why: removing them would strand un-migrated data on a node that has not yet
started once.

Both relaxations are pinned by the inverse of the test they replace
(Site_MissingSiteDbPath_IsAccepted..., EmptySqliteDbPath_IsAccepted...), each
verified to fail with the old rule restored.

Note: deploy/wonder-app-vd03/appsettings.Site.json is under a gitignored
deploy/ tree, so its edit is local-only and must be repeated on the box.

Joseph Doherty 037798b367 feat(localdb)!: replicate site config + sf_messages via CDC, delete the bespoke replicators
Tasks 14, 15 and 16, landed as ONE commit.

PLAN DEFECT: these three tasks cannot compile separately. SiteReplicationActor
takes a ReplicationService and calls ReplaceAllAsync (Task 14 deletes both);
DeploymentManagerActor Tells message types declared in ReplicationMessages.cs
(Task 15 deletes it); AkkaHostedService constructs the actor (Task 16). Any
ordering leaves a broken intermediate. Combining them also strengthens the
invariant Task 14 already stated for itself — the two mechanisms never both
run, and never neither.

Registered 8 tables in SiteLocalDbSetup.OnReady: sf_messages plus the 7 site
config tables. notification_lists and smtp_configurations are deliberately NOT
registered — permanently empty by design, so registering them would open a
standing replication channel whose only historical payload was plaintext SMTP
passwords. Migrate stays the LAST call in OnReady, after all registrations, so
migrated rows enter the oplog through live capture triggers.

Deleted: SiteReplicationActor, ReplicationMessages.cs, ReplicationService,
StoreAndForwardStorage.ReplaceAllAsync, and 6 test files. ReplaceAllAsync is
not merely unused but unsafe to keep: a mass DELETE on a now-replicated table
would be captured and shipped to the peer.

Kept ActiveNodeEvaluator (delivery gate + heartbeat still need it) with its doc
corrected, and activeNodeCheck in AkkaHostedService (SiteCommunicationActor).

The positional-argument hazard the plan flagged was real: removing
DeploymentManagerActor's optional IActorRef? replicationActor shifted 6
trailing optionals, and 4 test call sites bound the wrong arguments with no
compile error at some positions. Converted them to named arguments where
possible — Props.Create builds an expression tree, which rejects out-of-position
named args, so the rest are padded positionally with a comment saying why.

The Task 7 'not yet registered' test was INVERTED rather than deleted, and is
exact in both directions: too few means a table silently stops replicating, too
many means the SMTP tables leak. Added a separate security-named test for those
two, and a composite-PK test (LWW keys on the full PK, so a truncated key set
would collapse distinct rows). The convergence suites now get their
registrations from the real OnReady — their temporary harness registration is
deleted, so they prove the cutover rather than agreeing with themselves.

Verified: build 0 warnings; SiteRuntime 512, StoreAndForward 130, Host 330,
AuditLog 355, ExternalSystemGateway 142, HealthMonitoring 97, LocalDb

Joseph Doherty 79ce51612e test(site): pin the active-node notification-config purge; scope the guarded write
Task 12 + Task 13. No production behaviour change in either.

Task 12: DeploymentManagerActor.HandleDeployArtifacts already purges
notification_lists and smtp_configurations on every artifact apply, but nothing
pinned the actor's CALL to it — ArtifactStorageTests covers the storage method
only. Task 15 deletes SiteReplicationActor's copy, making this the sole
remaining call site, and Task 16 edits this actor's wiring; dropping the call
would leave plaintext SMTP passwords on disk with every suite still green.
Verified red-first by commenting the call out: the pin fails with that message.

Task 13: StoreDeployedConfigIfNewerAsync STAYS. Re-verified both callers —
SiteReplicationActor:375 (dies at Task 15) and SiteReconciliationActor:166
(survives). Reconciliation is a per-node startup self-heal against central
whose fetch races real deploys, so the deployed_at guard still does real work
there. Doc comment rewritten to say so, and to warn against porting the guard
onto the replication path where it would fight the HLC rather than help it.
Also corrected a stale 'guarded standby write' section header in the tests.

Re-ran the Task 13 step 2 scope check: ConfigFetchRetryCount's only production
reader remains SiteReplicationActor:157, so its option + validator rule stay
until Task 17, after Task 15 deletes the actor.

Verified: build 0 warnings; SiteRuntime 533, Host 329, StoreAndForward 153,

Joseph Doherty c56bf4ae65 test(localdb): port resync + config replication intents as CDC convergence specs
Task 11. Companion to Task 10, covering the intents held by
SiteReplicationActorTests and SfBufferResyncPredicateTests.

N1 Critical is re-expressed, not ported literally (D2). SfBufferResyncPredicate
existed because ReplaceAllAsync was a destructive DELETE-then-INSERT, so a
wrong-direction resync wiped a live buffer and the code needed an oldest-Up
predicate to decide authority. LocalDb's snapshot resync merges per row under
LWW and never deletes, so this asserts the property the guard protected — no
node loses rows to a peer's snapshot — with no directional-authority assertion,
because there is no active/standby asymmetry left to enforce. The setup is the
wipe scenario made concrete: each node writes rows the other never sees while
partitioned, plus a contended row, then they resync.

DEVIATION on the zero-fetch assertion. The plan asked for a fetcher test double
recording zero invocations; this harness has no actor system, no central and no
IDeploymentConfigFetcher in the graph, so the double would record zero calls
whether or not the fetch path still existed. An assertion that cannot fail is
worse than none, so the test proves the positive half — config reaches B over
replication alone — and the file records that the negative half is proved by
Task 15 deleting the code and the build still passing. It also records the D1
scope note: SiteReconciliationActor survives and legitimately fetches at
startup, so 'the standby never fetches, ever' would be false.

Non-vacuity verified by unregistering deployed_configurations: all 4 fail.

Joseph Doherty 2bbe66311d test(localdb): port store-and-forward replication intents as CDC convergence specs
Task 10. Specifications first, deletion second: the bespoke ReplicationService
(explicit Add/Remove/Park/Requeue over Akka) dies at Task 14, so its behaviour
is restated here as outcomes the CDC replacement must still deliver. Written
in terms of ROWS, not operations — under CDC there is no Add or Park message to
observe, only a row that must end up right on both nodes.

Not ported: ReplicationOperations_AreDispatchedInIssueOrder. It asserts the
mechanism (inline fire-and-forget dispatch), and CDC capture is asynchronous
and batched by construction. Its portable content is the ordering OUTCOME —
add-then-remove must never converge to present — which is a test here, with
that reasoning recorded in the file so it does not read as an accidental drop.

DEVIATION: extracted the Phase 1 fixture into LocalDbSitePairHarness rather
than duplicating ~150 lines. Phase 1's tests now derive from it and still pass
unchanged. The harness registers the Phase 2 tables itself, since production
OnReady does not until Task 14; that method is marked for deletion at the
cutover, and the 8-table list is written literally so a cutover registering the
wrong set fails these tests instead of agreeing with itself.

Non-vacuity verified by unregistering sf_messages: 6 of 7 failed. The 7th —
the ordering test — PASSED, because an absent row is also what a pair that
replicates nothing looks like. Fixed with a control row that must converge in
the same window, so the absence is evidence rather than silence.

Also corrected two comments from Task 9 that claimed Task 14 makes
notification_lists/smtp_configurations replicated. It explicitly does not
register them, for the same reason the migrator skips them.

Joseph Doherty 5ddc7eed6d feat(localdb): migrate legacy scadabridge.db config tables into the consolidated DB
Task 9. Seven of the nine site configuration tables are copied out of the
legacy scadabridge.db in a single transaction, with one rename at the end: a
partial config migration would leave a site node running against half its old
configuration, which is worse than failing startup outright.

notification_lists and smtp_configurations are deliberately NOT migrated.
Both are purged on every deploy and permanently empty by design since the
site write paths were removed (2026-07-10), but a pre-fix legacy file can
still hold rows — and smtp_configurations.password is plaintext. Task 14
makes these tables replicated, so migrating them would push plaintext SMTP
passwords across a channel whose only historical payload was exactly that.
The tables are still created; only their historical contents stay behind.

Generalizes Task 8's MigrateTable into MigrateFile(many tables, one
transaction, one rename), keeping the legacy/current column intersection.

Five tests, including a column-parity test asserting each declared column
list equals the live SiteStorageSchema's. That mismatch is otherwise
invisible: a typo'd column is silently dropped by the intersection, and a
missing one silently leaves data behind. Non-vacuity verified twice — once by
removing the Migrate call (3 fail), once by wrongly adding notification_lists
and smtp_configurations to the table map (the skip test fails).

Verified: solution build 0 warnings; Host 329, SiteRuntime 532,
StoreAndForward 153 — all pass.

Joseph Doherty bdc0dffea2 feat(localdb): migrate legacy store-and-forward.db into the consolidated DB
Task 8. Adds ResolveStoreAndForwardPath + MigrateStoreAndForward, wired as a
third call in Migrate alongside the two Phase 1 files.

Unlike the Phase 1 paths, the store-and-forward default sits INSIDE the data
volume, so a real deployment has a real file here holding undelivered
messages. This migration genuinely moves data; losing it would discard exactly
the buffered calls store-and-forward exists to protect.

No id synthesis: sf_messages.id is already a caller-assigned TEXT primary key,
so INSERT OR IGNORE is idempotent across a crash-then-rerun.

The copy intersects the legacy column set with the current one rather than
naming all 16 columns outright. A file from an older build predates
execution_id / parent_execution_id / last_attempt_at_ms, and naming a missing
column throws 'no such column' — which the existing reader treats as an
unrecognised shape and silently discards every row. A required-column (PK)
guard keeps that tolerance from degrading into copying NULL-keyed rows.

Four tests: copy+rename, crash-before-rename idempotence, the __localdb_oplog
assertion that catches migrate-before-register, and the older-column-set case.
All four verified to fail without the Migrate call.

Joseph Doherty f8aa02e2a9 feat(localdb): create config + sf_messages tables in the consolidated DB
Task 7. SiteLocalDbSetup.OnReady now applies SiteStorageSchema and
StoreAndForwardSchema alongside the Phase 1 schemas, so the nine site
configuration tables and the store-and-forward buffer live in the
consolidated LocalDb file.

Deliberately NOT registered for replication. The bespoke SiteReplicationActor
and the StoreAndForward ReplicationService still own these tables until the
Task 14 cutover deletes both and registers them in one commit; registering
early would run two replicators over the same rows and let either one's
defects hide behind the other's writes.

Pinned by two tests through the real composition root: one asserting all
twelve tables exist, one asserting ReplicatedTables is EXACTLY the Phase 1
pair. Non-vacuity verified by removing the DDL and observing the failure.

Joseph Doherty f2efeb37b7 refactor(sf,site): both stores take ILocalDb instead of a connection string
Tasks 5 and 6 of the Phase 2 plan, committed together because their test
fallout is entangled — several fixtures construct both stores.

StoreAndForwardStorage and SiteStorageService now take ILocalDb. Connections
come from ILocalDb.CreateConnection(), which hands out an already-open,
pragma-configured connection carrying the zb_hlc_next() UDF the capture triggers
call; a raw connection would lack the UDF and every write to a replicated table
would fail closed. Deleted with the connection strings: S&F's
EnsureDatabaseDirectoryExists and its per-open busy_timeout pragma, and the site
service's BusyTimeoutFloorSeconds normalization — LocalDb owns all of it now.

DI: AddSiteRuntime's string overload is gone (nothing left to supply), so the
Host calls the no-arg form. ScadaBridge:Database:SiteDbPath and
StoreAndForwardOptions.SqliteDbPath survive only as the migrator's source
locations in Tasks 8/9.

Two things the plan did not anticipate, both worth reading:

1. FOUND A REAL LATENT DEFECT, from Phase 1, now fixed. The plan assumed
   directory creation simply moved to LocalDb along with file ownership. It did
   not: the LocalDb library never creates the parent directory, and
   SqliteLocalDb opens the file eagerly in its constructor — so a missing
   directory is a hard boot failure ("SQLite Error 14: unable to open database
   file"), not a degraded start. The default site config points at the RELATIVE
   path ./data/site-localdb.db, so any site node without a pre-existing data/
   directory fails to boot. The docker rig escapes only because its volume mount
   happens to create /app/data — a coincidence that would have hidden this until
   a bare-metal or fresh deployment. This has been latent since Phase 1 made
   LocalDb:Path required; deleting S&F's EnsureDatabaseDirectoryExists here
   would have widened it. Re-established the guarantee at the layer that now
   owns the path (SiteLocalDbDirectory.Ensure, called before AddZbLocalDb) and
   pinned it with SiteLocalDbDirectoryTests. Non-vacuity is not assumed: two
   tests written against the wrong assumption failed with exactly this
   SQLite Error 14 before the fix existed.

2. Test fallout was ~7x the plan's estimate. The plan named "fixtures" in one
   project; the constructor change actually reaches 40 files across 7 test
   projects, and most used Mode=Memory;Cache=Shared — which LocalDb has no
   equivalent for, so every one had to move to a real temp file. Rather than
   copy the Phase 1 TestLocalDb fixture into 7 projects, added a shared
   tests/ZB.MOM.WW.ScadaBridge.TestSupport library (not a test project) so the
   WAL-sidecar cleanup and the "real, not stubbed" rationale live in one place.

Retargeted rather than deleted, in both directions: the S&F WAL test now asserts
against the LocalDb-backed store (WAL genuinely is LocalDb's job), while the
directory-creation test moved to Host.Tests (that guarantee is NOT LocalDb's).
SiteStorageServiceTests.Initialize_EnablesWalJournalMode got the same treatment.
DeploymentManagerMediumFindingsTests induced a persistence failure via an
unopenable path, which no longer reaches the assertion since the fixture now
throws first; it induces the same failure shape via an uninitialized store.

Verified: full solution build 0 warnings; SiteRuntime 532, Host 318,
AuditLog 355, ExternalSystemGateway 142, HealthMonitoring 97,
StoreAndForward 153 — 1597 passed, 0 failed.
