docs/specs and docs/plans were retired (prior commit); the source/test
comments that cited them ("spec 0050 §4.1", "spec §Testing N", "per spec",
"the spec's ...") now point at nothing. Strip every such pointer while
preserving the technical substance, the design-ledger contract refs
(C1/C11/C20/C34/C12.1/...), and the Gitea issue refs (#41).
Comment/doc edits only across 20 files — no logic change; full workspace
suite green, clippy clean.
The shipped Composite blueprint (ger40_breakout_blueprint) is now driven by the
World orchestration families on real GER40, with NO re-authoring — the #94
friction is gone:
- examples/ger40_breakout_sweep.rs — sweep the {entry_bar, exit_bar} grid built
directly from param_space() (best entry=3,exit=4 -> 214.0 over 2024).
- examples/ger40_breakout_walkforward.rs — non-degenerate walk_forward: a real
non-empty space optimized per window, chosen_params populated everywhere (#97).
- examples/ger40_breakout_compare.rs — one blueprint across two structural axes:
instrument (GER40 vs FRA40) and bar period (15m vs 30m — different strategies,
C34), no re-authoring.
- tests/ger40_breakout_world.rs — gated: sweep returns the ranked 9-point grid
over the two named params; walk_forward yields non-empty windows each with a
non-empty chosen_params (executable #97 proof).
No blueprint reshape needed — the factory returns a fresh (Composite, Taps) per
call, so the World families re-instantiate per grid point / window (the SMA-cross
pattern); baked recorders do not block multi-bootstrap.

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.

Run the Phase-1 session-breakout node vocabulary over REAL GER40 M1 bars
from the data-server archive — the first real-data exercise of the shipped
strategy nodes (Resample/Delay/Gt/Session/EqConst/And/Latch + SimBroker).
It is a pure composition of shipped aura-std nodes (no project-specific
signal code), so it lives in the engine repo's examples/ carveout (C9), not
a separate consumer crate. The breakout FlatGraph is reused VERBATIM from
aura-engine/tests/ger40_breakout.rs; only the sources change — four real
M1FieldSource (open/high/low/close, in the fixed C4 merge order) replace the
synthetic VecSources, with pip_size = 1.0 (GER40 is an index).
- examples/ger40_breakout_real.rs — runnable demo over a Sept-2024 window:
prints the RunReport metrics plus a per-session entry/exit trace.
- examples/shared/breakout_real.rs — the single 13-node wiring (the proven
11 + two trace taps), shared by the example and the test via #[path] so it
is never duplicated.
- tests/ger40_breakout_real.rs — gated determinism test (mirrors
real_bars.rs): skips where the archive is absent; where present, asserts
finite metrics, binary Latch exposure (held in {0.0, 1.0}), and
bit-identical C1 reruns of both the report and the recorded series.
chrono / chrono-tz added as aura-ingest dev-dependencies (the Session
timezone and the UTC window bounds), test-only — never on the normal path.
