Measure and ship performance gains

/goal Use the installed shape-goal and goal-engine skills to discover, approve, and complete this repository's next Measured Optimization / Benchmark objective. During shaping, load shape-goal's required-input specification for Measured Optimization / Benchmark; exhaustively inspect repository instructions, Git state and history, requirements, architecture, plans, tests and CI, runtime behavior, prior goal state, the project harness, and any connected authoritative sources before asking the user. Resolve every material input from evidence where possible; ask only unresolved owner decisions, one at a time with a recommended answer, and do not make production changes until the user approves a Goal Contract. Then hand off within this same goal to goal-engine to freeze the benchmark protocol, compare champion and challengers under identical conditions, and retain only meaningful improvements; apply relevant assurance overlays, repository-native verification, regression protection, independent review where warranted, durable progress state, and reusable closeout. Do not declare success when shaping is complete. Finish only when every approved acceptance and overlay gate passes with surfaced evidence and protected behavior has not regressed. Stop only for a contract-defined blocker, approval boundary, budget, material goal drift, or two consecutive no-progress cycles
