Documents existing GEPA implementation and outlines completion work needed: Existing Implementation (Complete): - Core GEPA algorithm with LLM-driven reflection and mutation (534 lines) - Pareto frontier management with per-example dominance tracking (275 lines) - Basic unit tests for GEPACandidate and ParetoFrontier - Budget control, statistics tracking, and lineage tracking Missing Components (To Be Completed): - End-to-end example demonstrating FeedbackEvaluator usage - Integration test with real OpenAI API - CHANGELOG documentation - Enhanced rustdoc with comprehensive usage patterns User Stories: - P1: Basic GEPA optimization with evolutionary search - P2: Track evolution progress and Pareto frontier statistics - P3: Budget-constrained optimization - P3: Dual-model setup for cost efficiency Reference: GEPA paper (Agrawal et al., 2025, arxiv:2507.19457) Pattern: Following BootstrapFewShot completion pattern (#1-bootstrap-fewshot) Co-Authored-By: Claude <noreply@anthropic.com>

…che (RFC 0002 IR-1) - ir::sig::SignatureDef/FieldDef/ConstraintDef/RenderSpec: a signature as an owned, serde-derivable runtime value; SignatureBuilder validates at finish() with the same rejections as #[derive(Signature)] (empty side, duplicate aliased names, bad format value, invalid jinja, check-without-label, malformed constraint expression, non-string map keys). - SignatureDef::of::<S>() bridges the derive statics (FieldSchema -> FieldDef, flattened fields keep leaf names); types_of::<S>() exposes the class/enum TypeTable from the same entry; matches::<S>() is the structural-equality check include_program! will use; augmented_with() is the value-lane Augmented<S, A>. - The remaining two leaked TypeId caches collapse into the single StaticSigCache: SignatureSchema::of now delegates to it (leak #1), and the per-derive OnceLock schema() fast path is no longer emitted (leak #4). Loaded programs own their arenas; nothing dynamic touches the cache. - Golden tests: derive-built == builder-built for representative signatures (plain, aliases+constraints+format+docs, class/enum tables, flatten, generic Augmented), serde round-trips, builder rejections, pointer-stable cache.
