GAP-PROC-002: Process Nesting and Sub-Process Invocation

Field	Value
Category	process-composition
Priority	High
Effort	L
Status	Missing

Description

Invoke a process from within another process as a first-class effect. Sub-processes inherit parent context.

Current State

No sub-process effect. Must use ctx.task() with agent kind as workaround.

Target State

ctx.subprocess() effect that invokes a child process. Child process inherits parent context. Results returned to parent as effect result. Child runs tracked in parent journal.

Dependencies

GAP-AGENT-001 -- sub-harness invocation for child execution

Key Files

Component	Path
Process context	`packages/sdk/src/runtime/processContext.ts`
Runtime	`packages/sdk/src/runtime/`

Recommendation

Phase 2 implementation. Add ctx.subprocess() as first-class effect. Create child run with parent context inheritance.
