 Native graph grants and transaction commit remain enforced by Camino outside
 the guest. Initialization and synchronous loops are subject to the same deadline.
 
+The default root/Package Invocation wall deadline is 10 seconds. The separate
+root CPU allowance remains at most 4 CPU seconds; extra wall time accommodates
+queueing and graph-port waits. Ordinary graph database transactions and idle
+transactions allow 30 seconds, and ordinary client HTTP requests allow 45 seconds
+so server failures can be returned. Nested calls inherit the remaining root
+budget; explicit smaller limits still apply. Restore/activation jobs retain their
+separate budgets. These defaults are starting limits, not latency targets.

 Direct network access, native filesystem imports, ambient clock and entropy,
 parent environment credentials, and unlisted modules are denied. Explicit dates,
 `Intl.Segmenter`, deterministic hashes and normal JavaScript computation remain
