Summary

Preserve failed approaches and other reusable evidence as distinct, target-neutral reflection lessons without deciding how downstream evolution stages will consume them.

Reasoning

Reflection is shared input for memory, skill, orchestration, and no-action decisions. Embedding a downstream target, filesystem destination, or final skill frontmatter choice during reflection would couple the evidence model to one later consumer.

Failed approaches also need to remain distinguishable from successful strategies so later stages can retain counterexamples, verification gaps, and tool behavior without flattening them into generic observations.

Changes

• Add a distinct evidence-grounded lesson kind for failed approaches.
• Instruct leaf and synthesis reflection to preserve successful strategies, failures, verification gaps, tool behavior, and counterexamples separately.
• Keep reflection output free of downstream target, destination, and final skill-format decisions.
• Version the updated Reflector prompt and update focused coverage.

User impact

Evolution reflection retains failed approaches more precisely and produces reusable lessons that later stages can evaluate independently for memory, skill, orchestration, or no action.
