Crate qta 

Streaming technical analysis indicators for quantitative trading.

Currently published: ZigZag swing detector (no-repaint, O(1) state).

PROVENANCE — load-bearing decisions captured elsewhere:

• Published on crates.io: see root CLAUDE.md for release workflow.
• Consumed via path dependency by flowsurface (fork-tools sibling).
• ZigZag algorithm and no-repaint guarantee: crates/qta/src/zigzag/mod.rs and the proptest suite in crates/qta/tests/invariants.rs.
• Range-bar-native threshold formula (τ = N × δ) and fixed-point FixedPoint i64×1e8 pricing convention: crates/qta/CLAUDE.md.
