Author the shipped session-breakout as a reusable Composite blueprint via GraphBuilder — the World-consumable form (param_space + bootstrap) — alongside the hand-wired FlatGraph it reproduces. Applies the spec-0051 decisions: - bar_period_minutes is a construction arg binding BOTH Resample.period_minutes and Session's period, locked equal, so a sweep cannot desync them (#96); - delay.lag is bound out (a structural constant, not a tuning knob — C34); - the two EqConst targets (named entry_bar / exit_bar) are the ONLY params, so param_space() == {entry_bar.target, exit_bar.target} — the genuine tuning knobs, which makes walk_forward non-degenerate (#97). The ger40_breakout_real example now bootstraps from the blueprint (still prints -45.0 for 2024-09). New gated test ger40_breakout_blueprint.rs proves: (a) the param_space is exactly the two targets (no lag, no period); (b) C23 — the blueprint reproduces the FlatGraph bit-identically over real GER40 2024-09; (c) determinism. First increment of the milestone; the sweep / walk_forward / compare World-family demos follow. refs #94, #96, #97
