Replay workflow DAG from recorded agent results

Reconstructing workflow execution DAGs from recorded results for visualization, audit, and re-execution without re-running agents; handles data-dependent fan-out and sub-workflows.

• · [object Object]

• · [object Object]

• · Script parser (JS/TS AST)
• · Topo order computation
• · Sub-workflow loader (via scriptPath references)

• · Script is valid JS (export const meta, phase(), agent() calls, parallel() calls)
• · records array contains real results from prior execution (or null if missing)
• · Data-dependent agent calls (fan-out from parallel results) are reconstructed from labels
• · Sub-workflows loaded recursively if scriptPath references present

• · Script syntax error → returns null (fail closed)
• · Unbounded agent loop → capped at ~5000 calls (prevents hang)
• · Recorded result missing for an agent → undefined agent result, node still recorded
• · Phase declared but spawned zero agents → placeholder phase kept (not dropped)
• · Sub-workflow reference broken (missing scriptPath) → child node recorded with subworkflow=undefined

• · Script is actually executable (not just inferred from AST)
• · Data-dependent fan-out reconstructed from recorded labels (not guessed)
• · Sub-workflows tagged with their name (subworkflow field)
• · Phase order preserved from script source
• · Unbounded loop protection prevents hang (call cap enforced)
