- Around line 657-658: Scope timeline task aggregation to the requested query’s
operators. In experimental/vibe/simulator/analyzer/src/lib.rs:657-658, build
query_operators from view.operators() and skip tasks whose operator_id is not
contained; apply the same filtering in the chunked dispatch loop at 805-806. At
1079-1091, pass the query scope into entities_filtered and enforce containment
in both filtering branches.
In `@experimental/vibe/simulator/analyzer/src/model.rs`:
- Around line 259-263: Update the task ingestion flow around the
TaskBuilder::try_new call to use a fallible entry path and propagate its error
through the enclosing AnalyzerResult instead of unwrapping. Preserve existing
task creation and event-push behavior for valid IDs while ensuring a nil task ID
returns an error rather than panicking.
In `@experimental/vibe/simulator/Dockerfile`:
- Line 18: Add a dedicated non-root user in the Dockerfile runtime stage, grant
it only the permissions required by the simulator binaries and runtime files,
and switch to it with a USER instruction before the runtime command. Verify the
simulator binaries continue to operate without root privileges.
In `@experimental/vibe/simulator/instrumentation/src/task.rs`:
- Around line 84-93: Update the Task FSM declaration to include sending as an
allowed exit state in exit_from and add the sending self-transition to
transitions, preserving the existing sending => queueing edge.
In `@experimental/vibe/simulator/ui/src/lib.rs`:
- Line 28: Update the is_resource method so it returns true only when self
matches EntityRef::Resource(_), while preserving is_resource_group unchanged.
