Placeholder-free 6-task plan for spec 0011 (refs #7). T1 scaffolds the aura-ingest crate + workspace member + unix_ms_to_epoch_ns (proves the data-server git dep resolves); T2 M1Columns + transpose_m1; T3 close_stream; T4 load_m1_window (data-server adapter, compile-gated against the real API); T5 the gated real-bars integration test (cycle-0007 sample harness over real AAPL.US close bars, finite + deterministic, skips where data absent); T6 full-workspace gates. Mirrors report.rs build_two_sink_harness with the shipped aura_std::Recorder. External data-server signatures verified against its source in the spec commit.
