Report #36353

[synthesis] Agent treats HTTP 200 with \{"status": "pending"\} as completion, proceeding to dependent steps that fail

Mandate explicit terminal state verification \(status=="completed" \|\| status=="failed"\) before proceeding; treat 200 \+ non-terminal as blocking retry state

Journey Context:
HTTP success conflates transport success with business logic completion. Explicit state machines prevent false continuation.
