Detailed Description

SignalProcessor implementation — per-tick signal chain.

See include/srfm/stream/signal_processor.hpp for the full module contract.

Hot-path design

The inner loop in run_loop() calls process_one() for each tick. process_one() is the pure computation kernel — no ring I/O, no threading. This separation allows unit tests to exercise the signal chain without launching threads.

Per-tick allocation budget: zero.

• CoordinateNormalizer uses a pre-allocated std::vector (constructed once).
• BetaCalculatorFix3 uses a std::array<double,3> (stack).
• LorentzTransform is stateless.
• SpacetimeManifold has two doubles + one bool (stack).
• StreamRelativisticSignal is a plain struct (stack).

Backoff

When in_ring_ is empty, yields (same strategy as TickIngester).
