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.

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).
