Detailed Description

High-level interface to the financial spacetime manifold.

Wraps SpacetimeInterval with convenience methods for common pipeline queries: causal character, normalised velocity, and regime classification.

Member Function Documentation

beta()

std::optional< double > srfm::manifold::MarketManifold::beta ( const SpacetimeEvent &  a, const SpacetimeEvent &  b, double  c_market = constants::SPEED_OF_INFORMATION  )

staticnoexcept

Compute the normalised 3-velocity β = |Δspace| / (c · |Δtime|).

This is the financial analogue of the relativistic β = v/c used by BetaCalculator. It measures how fast the "spatial" (price/vol/momentum) coordinates change relative to the market time axis.

Returns

β in [0, BETA_MAX_SAFE), or nullopt if:

• Δt = 0 (simultaneous events — undefined velocity)
• Any coordinate is non-finite

Definition at line 27 of file market_manifold.cpp.

classify()

std::optional< IntervalType > srfm::manifold::MarketManifold::classify ( const SpacetimeEvent &  a, const SpacetimeEvent &  b  )

staticnoexcept

Compute the spacetime interval between two events and classify it.

Returns

nullopt if any coordinate is non-finite.

Definition at line 15 of file market_manifold.cpp.

is_causal()

bool srfm::manifold::MarketManifold::is_causal ( const SpacetimeEvent &  a, const SpacetimeEvent &  b  )

staticnoexcept

True if the trajectory from a to b is causal (timelike or lightlike).

Definition at line 60 of file market_manifold.cpp.

process()

std::optional< IntervalType > srfm::manifold::MarketManifold::process ( srfm::CoordinateNormalizer &  normalizer, const SpacetimeEvent &  prev_normalized, const SpacetimeEvent &  curr_raw  )

staticnoexcept

Normalize curr_raw via normalizer, then classify the interval between prev_normalized and the resulting normalized event.

This is the canonical pipeline entry point. Every SpacetimeEvent is normalized before SpacetimeInterval::compute is called, preventing raw coordinate scale differences (price ~100, volume ~1e6) from dominating the interval computation.

Arguments

• normalizer — Rolling z-score normalizer (updated in place)
• prev_normalized — Previous event, already normalized
• curr_raw — Current event with raw market coordinates

Returns

Interval type of the normalized trajectory, or nullopt if any coordinate is non-finite after normalization.
