Configuration

The bundle ships with a conservative deployment profile:

- id: workflow-worker-thread
  disabled: true

- insert:
    - id: workflow-isolate
      name: dsh-workflow-isolate
      config:
        provider: spawn
        memoryLimitBytes: 67108864
        maxInterruptTicks: 250000
        maxAgentRequestBytes: 1048576
        maxWallTimeMs: 600000
        maxConcurrentAgents: 0
        maxTotalAgents: 1000
        maxItemsPerCall: 4096
        disposeGraceMs: 3000

maxConcurrentAgents: 0 asks the engine to derive a bounded value from available CPU parallelism. A profile's own cordis.patch.yml is applied after bundle layers and can replace this row's config. Cordis row configs replace rather than deep-merge, so restate every value you need when overriding it.

Resource limits are deployment policy, not script options. Lower them for exposed or multi-user deployments, and remember that child-agent cost is primarily controlled by maxConcurrentAgents and maxTotalAgents, not QuickJS memory.

Millisecond timer settings are capped at Node.js's maximum single-delay value (2,147,483,647) so oversized values cannot be clamped to an immediate timeout.

All engine defaults are listed below. The bundle patch relies on static defaults for values it does not restate.

Key	Default	Purpose
`provider`	`spawn`	Host-side subagent provider
`memoryLimitBytes`	64 MiB	QuickJS guest heap ceiling
`maxStackBytes`	1 MiB	QuickJS interpreter stack ceiling
`maxInterruptTicks`	250,000	QuickJS interrupt-fuel budget per run
`maxScriptBytes`	256 KiB	UTF-8 workflow body ceiling
`maxResultBytes`	1 MiB	UTF-8 serialized final-result ceiling
`maxAgentRequestBytes`	1 MiB	UTF-8 JSON ceiling for one prompt and its agent options
`maxWallTimeMs`	600,000	Host-observed run deadline, including child waits
`workerMemoryLimitMb`	128 MiB	V8 old-generation ceiling for the worker bridge
`maxConcurrentAgents`	`0`	Auto-resolves to `min(16, max(1, availableParallelism() - 2))`
`maxTotalAgents`	1,000	Accepted `agent()` calls per run
`maxItemsPerCall`	4,096	Items per `parallel()` or `pipeline()` call
`disposeGraceMs`	3,000	Cleanup grace before forced worker termination
