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.

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.

Flow Debugger (design 2026-09-05 §5.1/§5.2): the context is the single funnel for
SetAttribute / WriteBatchAndWait / WaitInternal, so it emits the write/wait rows (collector
first, then the best-effort IAuditWriter whose redactor applies the payload cap), stamps
Trace on SetStaticAttributeCommand and ScriptCallRequest, and hands the flag + sink to the
inline CallShared child context. Untraced contexts emit nothing (pinned).
