A traced run refused before launch — by the per-script in-flight cap
(MaxConcurrentRunsPerScript) or by MinTimeBetweenRuns — emitted no ScriptTrace row at
all, so the Flow Debugger reported NO_TRIGGER_WITHIN_WINDOW ("no value-change trigger on
this attribute, or no device echo"), which is wrong in both cases and sends the operator
to check the wrong things.
Both guards now leave a Failed ScriptTrace/ScriptRun row naming the guard that refused
the run, parented to the writing execution and carrying the trigger detail. The new
ScriptRunLauncher.EmitSuppressedRun reuses EmitScriptRun with elapsedMs 0 and no
collector (a shed run has no reply to ride on — the row reaches the debugger via
PullTraceEvents / Replay), resolving the writer and identity providers from a fresh
scope because it runs on the actor thread. Best-effort, never throws, no-op untraced.
