- ScriptLogRateLimiter.LimitPerWindow. The ScriptLogTopicSink and
VirtualTagActor summaries now print the configured limit, not
DefaultLimitPerWindow. Tests assert "limit N/window" for a non-default
N.
- CalculationDriver.Dispose cancels, then takes _evalGate (bounded 2 s)
and disposes the gate and _evalCts. The pump and timer ticks enter the
gate through TryEnterEvalGateAsync, which stops cleanly once the
driver is disposed. Test: Dispose with a 6 s runaway run in flight
returns promptly, disposes both, and a late trigger is harmless.
- ScriptedAlarmEngine captures _shutdownToken once and disposes
_shutdownCts in Dispose when every drained task has completed. A task
stuck past the grace leaves the CTS to the GC. Lifecycle tests assert
the disposal.
- DraftValidator: CalculationNoEffectiveTrigger is skipped for a
change-triggered tag whose scriptId does not resolve. That case is
already CalculationScriptMissing or CalculationScriptNotFound, and
there are no reads to count. Both existing tests now assert the
absence (red before the change).
- docs/VirtualTags.md: System.Threading is denied as a whole namespace,
with an allow-list; the type list is now accurate (Unsafe,
RuntimeHelpers, and the ForbiddenMembers on System.Type); the resource
limits section covers the run guard and the allocation budget.
docs/ScriptEditor.md: accurate deny-list and a new "Runtime safety"
section covering timeout, refusal, quarantine after 3 timeouts,
allocation budget, lifting, and rate-limit summaries that appear only
on the source's next entry after a burst then quiet.
