Central rows carry central's clock, site rows the site's, so the global
OccurredAtUtc sort let a 1-2 s skew float a whole site execution ahead of the
inbound row / RouteCall that started it, and pushed the trigger-cascade spawner
search onto its parentChain[0] fallback.
FlowGraphBuilder.Build now orders executions by the input index of their
earliest-given row and orders steps by timestamp only INSIDE one execution
(one clock), breaking ties by kind rank then input index. A folded outbound
node keeps its earliest-by-time row's identity, which need not be the row given
first, so its index is the minimum over the rows folded into it. The spawner
search uses position in the ordered list rather than a raw timestamp compare.
FlowDebugRunner.RunMethodAsync keeps the collector's emission order instead of
re-sorting; the value-change path keeps its OrderBy (all rows share one site
clock). Replay input arrives timestamp-sorted from the repository, so its order
is unchanged.
The DelmiaShaped test fixture is still shuffled within each execution (the
inside-one-execution timestamp rule is unchanged) but now lists the executions
in emission order, since that is what fixes their relative order.

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).
