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.
Aggregates a fine 4-field OHLC stream into period_minutes buckets (open=first,
high=max, low=min, close=last), emitting a completed bar ONLY on bucket rollover
(ctx.now() crossing into the next bucket) — C2: a bar is actionable only once
complete, partials are never emitted and the last partial bar is dropped (no EOF
flush). Four Barrier(0) f64 inputs, a 4-field f64 record output (the first
multi-field-output node in aura-std, mirroring the Ohlcv engine fixture). The bar
carries no timestamp; the engine stamps the close-instant. Build-step 6 of
milestone 'Strategy node vocabulary I'.
