Report #103316

[synthesis] Agent recovered from an error by skipping the failed step, but the remaining plan assumed the failed step's side effects existed

Every plan step must declare its outputs and successors. If a step fails, the planner must explicitly replan from the current state, not skip. Failed steps must either produce a compensating action or halt; they cannot be silently elided.

Journey Context:
Skipping feels efficient, especially when the failure looks minor. But downstream steps often depend on invisible side effects: a created directory, an initialized variable, a written config. The agent cannot see these dependencies unless the plan encodes them. The robust pattern is a dependency graph with explicit replanning on failure. This is more expensive than linear execution, but it is the difference between a graceful abort and a quiet cascade.
