Per-cycle fieldtest of the aura-ingest ingestion boundary (issue #7), from the
public interface only. 3 examples (transpose/normalize core; close_stream ->
deterministic harness run with epoch-ns end-to-end; load_m1_window over real
AAPL.US 2006-08 bars + None paths), all green. 0 bugs, 0 friction.
Two spec_gaps named for follow-up (neither a code defect; both filed to the
tracker):
- load_m1_window returns Some(empty M1Columns) — not None — for an in-coverage
but bar-empty window. The rustdoc's "None if no data in [from_ms,to_ms]" reads
bar-level but the realized boundary is file-level (it inherits data-server's
file-skip None). A consumer matching None == "no bars" is wrong for the
in-coverage-empty case. -> tighten the load_m1_window rustdoc (one line).
- AAPL.US (the carrier/integration-test symbol) has only ~21 M1 bars/month, so
the SMA-cross never warms and the end-to-end run yields all-zero (degenerate
but valid) metrics. The boundary is correct (C2 warm-up); the milestone's
shipped demo data is too thin to show a non-degenerate trace. -> weigh against
C22's "newcomer sees a populated trace" before the Walking-skeleton close
(document expected density or name a denser demo symbol/window).
