Detailed Description

Applies a 1+1D Lorentz boost to tick coordinates.

Maintains no persistent inter-tick state beyond what SpacetimeManifold needs. Stateless in the physics sense — transform() is a pure mathematical operation given (t, x, β).

LorentzTransform lt;
auto ev = lt.transform(bar_idx, norm_close, beta_calc.beta());
// ev.t_prime, ev.x_prime feed into SpacetimeManifold

◆ inverse()

TransformedEvent srfm::stream::LorentzTransform::inverse	(	double	t_prime,
		double	x_prime,
		double	beta
	)		const

inlinenoexcept

Inverse Lorentz boost: recover (t, x) from (t', x') given β.

Uses the inverse transformation: t = γ · (t' + β·x') x = γ · (x' + β·t')

Note: noexcept.

◆ lorentz_gamma()

static double srfm::stream::LorentzTransform::lorentz_gamma ( double beta )

inlinestaticnoexcept

Compute γ = 1/√(1−β²) for a given β.

Convenience function; returns 1.0 for invalid inputs.

Note: noexcept.

◆ transform()

TransformedEvent srfm::stream::LorentzTransform::transform	(	double	t,
		double	x,
		double	beta
	)		const

inlinenoexcept

Compute the Lorentz-boosted coordinates for a single tick event.

Parameters

t	Raw time coordinate (bar index, cast to double).
x	Normalised space coordinate (z-score close price).
beta	Market velocity β ∈ (−BETA_MAX_SAFE, +BETA_MAX_SAFE). If \|β\| ≥ 1 or non-finite, treated as 0 (identity boost).

Returns: TransformedEvent with boosted (t', x'), γ, and β recorded.

Note: noexcept — pure arithmetic, no allocation.
