One carrier. Two linked responses.

Where the arguments meet

Cross-Domain Spectral Ratio Structure: Refined Recurrence, Robustness and Diagnostic Limits →
Ordered spectral-ratio profiles recur across several hydrogen and image readouts, with more moderate Kerr comparisons. The full controls distinguish reproducible structure from exclusive privilege of the original library.

From Source Structure to Spectral Profiles: Generation Mechanisms and Observable Readouts in the Canonical Spectral-Curvature Framework →
Hydrogen radial shells, Gaussian exchange and Kerr resonance boundary conditions generate spectral profiles by distinct mechanisms. Exact counterexamples and calibrated responses show what pooled ratios lose and what observations recover.

Adaptive Spectral Carriers: Time Ordering, Reciprocal Memory, and Linked Coherent–Dissipative Response →
Reciprocal memory changes the carrier along the trajectory. Instantaneous alignment survives along realized histories, while time ordering and full feedback change the response.

Sustained Adaptive Spectral States: Global Attraction, Nonlinear Gain, and Linked Coherent–Dissipative Response →
A declared rate port sustains nonzero states, with global attraction under a strict curvature condition. Nonlinear gain and freely responding memory distinguish the adaptive system from a matched fixed carrier.

Sharp Uniqueness and Bistability in Driven Adaptive Spectral Carriers →
A sharp curvature threshold gives uniqueness even at equality. Below it, the three-node realization exhibits bistability, with a complete stationary count in the stated transverse-convexity regime.

Slow Passage and Prepared Hysteresis in Adaptive Spectral Carriers →
A slow sweep delays switching past the static fold by a preparation-dependent amount. The prepared cycle has a nonzero geometric loop limit, while physical maintenance work grows as the sweep slows.

Transport and Projective Reduction in a Source–Readout Derivation of Einstein Gravity →
Reconstruct the affine connection from smooth transport, remove the projective ambiguity with a volume-restored observable, and follow the complete off-shell spin-two bootstrap to Einstein–matter dynamics within the admitted realization.
