Rig-only posture, set in the tracked docker/central-node-{a,b}/appsettings.Central.json
so it survives deploy.sh / container recreates (it used to be a throwaway compose
override on central-a alone). Both nodes so Traefik on :9000 is login-free
regardless of which node is active. POST /auth/login still answers 302, so the
Playwright fixture login is unaffected; LoginTests will fail on this rig by design.

Notify.Send mints NotificationId as Guid "N" (no dashes) and the outbox parses it back into
the audit row's CorrelationId, so the Flow Debugger's Notify node linked and relayed a "D"
string the Notifications table never matches (found live: the report opened empty). The
link and RetryNotificationRequest now use "N", and the Notification report normalises any
Guid-shaped ?correlationId= to "N" so Audit Log and Flow Debugger callers both land.

An ephemeral inbound method (created and deleted through the CLI, with a never-taken
Route.To branch so prediction resolves a route target) is run live in a real browser through
the fixture's /auth/login; the reload test drives the OnAfterRenderAsync localStorage restore
and then proves the page is still interactive. Both fail on the pre-fix image at the
'Predicted' wait (the circuit deadlock) and pass on the fixed one.

The page wires FlowStepDetail's OnRetry/OnDiscard to IFlowDebugService.RetryOutboundAsync /
DiscardOutboundAsync behind the same site-scope re-check and confirm wording the Site Calls /
Notification report pages use, toasts the relay outcome, and on success re-polls Replay (same
5 s / 2 min loop) until the acted node leaves Parked. Also drops a duplicated ?correlationId=
test block that a concurrent index-only commit left in QueryStringDrillInTests.

FlowDebugService.PredictMethodAsync resolved route targets with a sync-over-async
GetAwaiter().GetResult() inside the predictor's synchronous resolver — on the circuit's
single-threaded renderer sync context that blocked the dispatcher forever the moment a
method whose script routes to a site script was chosen (every later click and JS-interop
reply queued behind it; the page looked inert with a healthy websocket and no error).
Misdiagnosed on 2026-09-06 as a login-disabled localStorage stall. Now a resolve-and-rewalk
loop: each pass records the targets it could not answer, they are awaited between passes,
and the walk converges once a pass asks for nothing new (bounded by MaxPredictionPasses).
Regression test drives the service under a single-thread pump sync context (fails in 10 s
on the old code, passes now) plus a nested Scripts.Call resolve-across-passes test.

Rig run 2026-09-06 (image built from this branch, containers recreated from
main's compose file): full drill A-H YES (active-central kill takeover 27 s,
rejoin as standby in 3 s), then with FLOW_ONLY=1:
H live+replay -> YES
live: YES root=8e628d0a-428b-48df-b937-f4c2ac631fc3 events=8 api=Delivered db=Delivered notify=Submitted
replay: YES root=8e628d0a-428b-48df-b937-f4c2ac631fc3 events=10 api=Delivered db=Delivered notify=Delivered
I outbound live+replay -> YES
Two rig facts the drill established: (1) with the DB reachable the site's
immediate-completion path resolves a CachedWrite INSIDE the run, so the DbCall
node is already Delivered inline (Submit/Attempted/Resolve share a tick — the
check now ranks statuses instead of taking list order); (2) cached-call
telemetry reaches central on its own ~20-30 s cadence, later than the 5 s audit
push, so replay needs the bounded retry. New FLOW_ONLY=1 switch runs H + I
without the notifier build or the docker kill.

After a successful Live run whose graph has Pending outbound steps the page
re-reads the tree through the existing Replay command every 5 s for up to
2 min (page constants), merging by replacing the graph and keeping the
selection by event id; never in Replay mode; cancelled by a new run, a mode
switch or Dispose. Status strip gains a Pending count, a 'Refresh outcomes'
button (both modes) and an 'outcomes still arriving' note while polling. The
run's own timing and the Completed chip are left alone — pending outbound
work is not a failed run. Plan 2026-09-06 D5.

A folded outbound step shows a Lifecycle tab (time · kind · status · node ·
error, oldest first; a Parked step adds the 'retry or discard from Site Calls /
Notification report' hint), replaces the never-populated Writes tab for those
steps, labels the Input tab Request / SQL + parameters / Subject + body by kind,
and 'Where this ran' names the System / Connection / List plus 'Delivered by'
(the terminal row's node). Pending/Parked outcome badges.

Four lanes (LaneCount 4; External sublabel = distinct targets, three then +n);
ApiCall/DbCall/Notify nodes carry a status pill (Ok/Pending/Parked/Failed —
pending pulses, reduced-motion aware) plus a sync/cached/notify mode; folded
lifecycles show '+4.1 s' submit→terminal wall time. Async edges are dashed
and routed through the inter-lane strip with a gutter tag; spawn edges use a
bolt marker. Predicted async edges (Task 6's PredictedEdge.Async) render the
same way. de-DE height pinned at 319.2 = (4×110+16)×0.7.

Review of Task 3: the sink invoke sat before WriteAsync/ForwardAsync inside the
best-effort try, so a throwing sink would have silently dropped the durable
row. GuardTraceSink wraps the delegate in every helper ctor (and Collect
guards EmitTrace); pinned by a throwing-sink test. ScriptRunLauncher no longer
allocates a collector for a traced run with no reply target (Nobody) — the
list would never be read. FlowTraceCollector.Complete pinned at unit level;
Snapshot documented as a non-closing peek.
Claude-Session: https://claude.ai/code/session_01NcMG6xXdsJbmD2wYAgkK29
InboundDatabaseHelper gains trailing optional auditWriter / nodeIdentity /
executionId / parentExecutionId / methodName / traceSink parameters; every
QuerySingle/Query/Execute writes one DbOutbound/DbWrite row (Delivered/Failed,
Target = connection name, Actor = 'api:{method}', DurationMs, SQL + parameters
as RequestSummary, Extra in the site's {op, rowsAffected|rowsReturned}
vocabulary, SourceNode) via ICentralAuditWriter — best-effort, never into the
script; the same instance goes to the RouteHelper trace sink first. Closes the
audit-scope gap Component-AuditLog.md already claimed (plan D7). Redaction and
the 8 KB cap apply at write time in the shared redactor, as for site rows.
Claude-Session: https://claude.ai/code/session_01NcMG6xXdsJbmD2wYAgkK29
FlowShapePredictor emits ExternalSystem.Call/CachedCall → ApiCall ('{s}.{m}'),
Database.Execute/Query/QuerySingle/CachedWrite → DbCall ('{conn} · {member}'),
Notify.Send(list) and Notify.To(list).Send() → Notify ('Notify {list}'), all on
FlowLane.External; Async-suffixed spellings map identically. PredictedEdge gains
an additive Async flag; an async edge (cached call, notify) does not advance the
chain, mirroring FlowGraphBuilder.IsAsync (D4/D8). Database.Connection() raw
handles no longer predict a node (command count is not statically knowable).
Claude-Session: https://claude.ai/code/session_01NcMG6xXdsJbmD2wYAgkK29
ScriptRuntimeContext caches a trace sink (null on an untraced run, so the
production path is byte-identical) and threads it into the ExternalSystem /
Database / Notify helpers and AuditingDbConnection→AuditingDbCommand (onAudit).
All eight outbound emit sites hand the SAME AuditEvent instance to the sink
first, then to the writer/forwarder. FlowTraceCollector gains Completed +
Complete(): ScriptRunLauncher closes the collector where it builds the reply
snapshot, so un-awaited calls finishing after the run returned never mutate a
list the reply was built from. Cap (500) unchanged. Plan 2026-09-06 D5.

Review of Task 2 (2026-09-06 outbound-calls plan): (1) an outbound step that
precedes the first chain step of its execution — the default Replay shape when
a run's ScriptTrace rows are absent — was orphaned or given a solid spawner
edge; leading async steps now hang off the spawner on Async edges and the
first non-async step gets the normal link. (2) IsAsync keyed on the first row
being CachedSubmit; it now mirrors the projector's sync rule (first row not
ApiCall/DbWrite) so a group missing its submit row still branches. (3) Same-
tick rows tie-broke by GUID; new LifecycleRank (submit < attempt < resolve,
non-terminal < terminal) makes first/latest attribution order-independent.
(4) DbSubtitle used GetInt32 (FormatException on out-of-range/fractional) —
now TryGetInt32, never throws. Also: External-lane edges never count as
central↔site crossings; DurationMs clamped; FlowStep doc updated.
Claude-Session: https://claude.ai/code/session_01NcMG6xXdsJbmD2wYAgkK29
GetTraceEventsAsync widens its channel filter to ScriptTrace ∪ ApiOutbound ∪
DbOutbound ∪ Notification ∪ (ApiInbound & InboundRequest) (plan D6); SecuredWrite,
Cluster and InboundAuthFailure rows in the same tree stay excluded. The site
SqliteAuditWriter.ReadByExecutionIdsAsync already had no channel predicate — pinned
by a test. Interface doc updated to match.
Claude-Session: https://claude.ai/code/session_01NcMG6xXdsJbmD2wYAgkK29
Fold rule: outbound rows sharing (kind, CorrelationId) become one FlowStep with
a Lifecycle list — first row's identity/time/input, latest row's outcome/
subtitle/output/error, DurationMs = sync row's own or submit→terminal wall time
(null while pending). Chain skips async steps (Notify, or first row
CachedSubmit) and links them with Async edges from the preceding chain step.
Spawner edges from a non-RouteCall are Spawn: true. The Response links from the
last non-async step of the inbound execution (the RouteCall), not the globally
last cascaded step (D9). FlowGraphView places a Response at max column + 1 so
the D9 origin does not pull it left (pulled forward from Task 7 to keep the
layout test green).

Gap verified 2026-09-06: the projector and predictor already know the three outbound
channels, but the live FlowTraceCollector is fed only by EmitTrace (writes/waits) and
the replay query filters to ScriptTrace + the inbound row, so a run leaves every
predicted outbound node as a ghost. Central method-script Database.* calls are not
audited at all.
Plan (11 tasks): three step kinds ApiCall/DbCall/Notify on a fourth External lane;
one node per operation with the cached/notify lifecycle folded in (Pending/Parked
outcomes, Lifecycle tab); sync calls in the chain, async ones on dashed branch edges;
site rows ride the existing collector, replay filter widens, central DB helper gets
DbOutbound rows; the page refreshes pending outcomes via the existing Replay command;
spawn edges styled and Response linked from the route call (the "two parallel paths"
question). Mockup: docs/plans/…-mockup.html, published as a Claude artifact.

The swimlane's node text was clipped by character count (20/24), so dotted attribute
paths showed only their shared head ("DelmiaReceiver.Reci…" five times in a row) and
the subtitle spilled past the box. It was also unstyled: the SVG <text> elements are
emitted as raw markup (Razor reserves the <text> tag), so they never carried the CSS
isolation scope attribute and every .fg-* rule silently missed.
- Node body is now HTML inside an SVG foreignObject: the browser measures the text,
the title wraps to two lines and ellipsizes by width, the subtitle by width on one
line, nothing can overflow the box, and the div's title attribute carries the full
unstripped text as a tooltip. Node height 78 -> 84.
- A lane whose real titles share a dotted head (CommonDottedPrefix) shows it once in
the lane gutter ("DelmiaReceiver.*") and each node shows only the tail that tells
it apart; the write subtitle strips the same head per item. Predicted-only nodes
are never stripped.
- WrapHints inserts zero-width spaces at camel-case and ./_/ boundaries so a wrapped
title breaks at "DelmiaRecipe|Download" rather than mid-word.
- Gutter widened 130 -> 160 with the sublabel clip raised to 22 so "site-a · DelmiaSim01"
fits; the remaining SvgText gutter labels are styled through ::deep.
Verified live on the rig (replay of the Task 22 run): all three lanes readable, no
overflow, gutter shows the factored prefix. CentralUI suite 1199 pass.

Rig recreated from the branch-built image through the main checkout's compose file
(deploy.sh refuses a worktree, register row 68). Fresh key delmia-flowdbg-0906 scoped to
DelmiaRecipeDownload. Full drill: A/B/E/F YES, C/G NO, takeover 29 s, rejoin 3 s, then
H live+replay -> YES
live: 11 events (InboundRequest, RouteCall, ScriptRun, 7x AttributeWrite, AttributeWait)
replay: 17 events on the first attempt — the six extra rows are the simulator's two
cascaded ValueChange runs (2x ScriptRun + 4x AttributeWrite): inline TraceEvents
carry the routed run's own steps, replay walks the whole execution tree.
Recorded as row H in Delmia-Recipe-Download-API.md §8; ledger marks Task 22 completed

Both central nodes gain a root AuditLog:PerChannelRetentionDays:ScriptTrace=30 (validator

runs flow-debug run-method with the drill parameters and asserts completed=true plus the
kind set {InboundRequest, RouteCall, ScriptRun, AttributeWrite, AttributeWait} from each
event's detailsJson, then flow-debug replay on the root ExecutionId with the same check,
retried up to 40 s for the 5 s site telemetry push; prints 'H live+replay -> YES'.
VERIFICATION PENDING: the image scadabridge:latest was built from this branch
(docker/build.sh, exit 0) but the containers have not been recreated and step H has not
run yet — the next step is a recreate through the MAIN checkout's compose file (deploy.sh

Dependency-free inline SVG: three fixed 110px lanes (Central / Site / Tags, sublabelled
from the steps' site/instance), columns from a topological pass over the graph edges with
same-lane collision bumping so independent siblings never overlap, 150x78 nodes on a
130+col*170 grid, orthogonal connectors with arrow markers (accent for boundary crossings,
dashed for external actors, light for predicted edges). Renders a real FlowGraph, a
PredictedFlow (dashed nodes, input-dependent finer-dashed), or both — predicted nodes
matched to real steps by kind in order, the leftovers appended greyed as ghosts. Selected
node = accent 2px on --active-bg; failed/timed-out/not-traced outcomes styled; each node a
role=button tabindex=0 <g> with click + Enter/Space selection; svg role=img with a summary

IFlowDebugService/FlowDebugService (scoped, registered beside IDataConnectionMoveService).
Run/replay go to the per-node ManagementActor through ManagementActorHolder with the Blazor
principal projected to AuthenticatedUser, exactly as DataConnectionMoveService does; the
FlowDebugRunResult payload is deserialised (camelCase) and fed to FlowGraphBuilder, while
ManagementError/Unauthorized/holder-null/transport faults collapse into FlowDebugOutcome
with the server's error code verbatim (STANDBY_NODE reaches the page untouched). Prediction
is DB-only: PredictMethodAsync hands FlowShapePredictor a memoised resolver that maps a
route target → Instance.UniqueName → template parent chain (nearest definition wins, cycle
guarded) → TemplateScript.Code; PredictValueChangeAsync roots at the write and appends each
script whose value-change trigger names the attribute (same attributeName/attribute keys
the site's TriggerRouting parser reads).

Pure Roslyn syntax walk (SourceCodeKind.Script, no semantic model, DB-free) that turns a
method or site script into PredictedNode/PredictedEdge chains in source order: Route.To(x)
.Call/SetAttributes/WaitForAttribute, Scripts.Call, Attributes.WriteBatchAndWaitAsync/
WaitAsync/WaitForAsync/SetAsync, Attributes[x] = v, ExternalSystem/Database/Notify. String
literals resolve; anything else is InputDependent with the expression text as title. An
if-return guard becomes a note on the node that follows it (condition visited first, so a
guard whose condition IS the traced call — Delmia's WriteBatchAndWaitAsync — attributes
correctly). Routed/nested script bodies come from a caller-supplied resolver, recursion
capped by maxDepth; parse errors and any walker fault degrade to request+response with a
'parse error' note. Predicted kinds are exactly the traced kinds so the page can overlay by
kind + title. Deviation from the plan's node count: no separate central 'method script'
node — the real graph records none, so the InboundRequest node stands for it.

Flow Debugger (design 2026-09-05 §7.1): FlowDebugRunMethodCommand / FlowDebugRunValueChangeCommand /
FlowDebugReplayCommand on the per-node ManagementActor (Deployer role; the two run commands
are long-running), all delegating to FlowDebugRunner. RunMethod refuses on a standby with
STANDBY_NODE (ManagementCommandException now carries an optional Code that replaces
COMMAND_FAILED), validates parameters through the real ParameterValidator/SchemaRefResolver
(made public), synthesizes the inbound row (actor = operator, Extra.source = flow-debugger)
and runs the method through InboundScriptExecutor with a trace-sink RouteHelper so the reply
carries the RouteCall row + the site's inline events. RunValueChange does a traced routed
write via IInstanceRouter, then polls IPullTraceEventsClient (interface moved to Commons so
ManagementService can consume it) until a ScriptRun parented to the root settles, else
NO_TRIGGER_WITHIN_WINDOW. Replay reads IAuditLogRepository.GetTraceEventsAsync.
