Milestone-close gate for "The World, part II — orchestration families".
Four end-to-end scenarios derived top-down from the milestone promise,
each built from HEAD and run as a downstream consumer through the public
API + CLI only (no crates/*/src read):
- mw_3 (headline): real EURUSD-M1 walk-forward composing all four axes
(grid sweep + optimize in-sample, OOS stitch) over the M1FieldSource
seam + lineage — 5 windows, 145 200-pt stitched curve, C2 held.
- mw_2: monte_carlo over 128 seeds, reproducible McFamily (C1) + aggregate.
- mw_1: random sweep -> optimize -> 64-member lineage round-trip.
- mw_4: family-lineage CLI transcript.
Findings: 4 working (promise empirically delivered), 1 bug, 3 friction.
- bug F5: `aura runs list`/`rank` cannot read a pre-0047 runs.jsonl — the
cycle-0047 typed-Scalar params migration (86746e3) left the persisted
flat store unmigrated; load() fails at the first bare float (+ exits 0).
- friction F6: no epoch_ns_to_unix_ms inverse for real-data walk-forward.
- friction F7: DataServer/DEFAULT_DATA_PATH not re-exported by aura-ingest.
- friction F8: family store is directory-keyed, undocumented on Registry::open.
